The use of catalytic technology is essential for several of our critical sustainability issues. Therefore, competence and research within this field, is vital if we shall succeed in the transition to sustainable systems for transport, chemical and material production, and energy conversion.<br /><br /></div> <div> </div> <div><img src="/SiteCollectionImages/Institutioner/KB/Generell/Nyheter/anslag%20kompetenscenter%20Katalys%20och%20kärnenergi/Magnus%20Skoglundh%20200x200.jpg" alt="portrait Magnus Skoglundh " class="chalmersPosition-FloatRight" style="margin:5px" />“The main property of a catalyst is that it lowers the energy barrier required for the reaction to take place. Instead of 300 degrees, it can for example proceed at room temperature, Magnus Skoglundh explains.”<br /><br /></div> <div> </div> <div>In the upcoming period, the center will focus on greenhouse gases to a greater extent than emissions, which they are already strong in. Further, the research on synthesis and production of fossil-free energy carriers will increase. Electrocatalysis is a large part of the center’s work and development of fuel cells, which is an important component for the future fossil-free society. They will also introduce a completely new part - energy efficient and greener chemical industry. The center has many exciting research projects underway. Right now, they are for example working on reducing nitrous oxide emissions, where they are internationally leading.</div> <div> </div> <div><br /></div> <div> </div> <div>One of the center's most important purposes is to train skilled engineers, licentiates, doctors and senior researchers, who can implement what they have learned in the industry. The collaboration with the business community has been ongoing from the start. Today, there are eight member companies in the competence center. At Chalmers, researchers in chemistry and physics have been included and now it will be further broadened with researchers in energy system analysis​.<br /></div> <div> </div> <h2 class="chalmersElement-H2">Premiere for nuclear technology support </h2> <div> </div> <div>Among the Swedish Energy Agency's designated competence centers, there is also research and competence in nuclear technology.

The monomeric ink is extruded from a print head onto a heated bed triggering the frontal polymerization (FP) reaction. Heat released from the polymerization activates adjacent monomer to further the curing process, thereby forming a self-sustaining propagating reaction wave that polymerizes the printed filament. The stiff polymerized segment of the filament can structurally support the printed part during its fabrication to produce three-dimensional (3D) free form printed structures with excellent fidelity. Fabricated parts exhibit a degree of cure of 99.2% and do not require further post-processing.  The addition of nanoparticles and other reinforcement phases allows access to a range of rheological profiles between low-viscosity liquid and free-standing elastomeric gel – all of which frontally polymerize upon thermal activation. This presentation will summarize the characterization of ink rheology for printing, influence of printing parameters, addition of reinforcing fillers, and the resulting mechanical properties of the printed structures.</span></li></ul></div>Wed, 22 Dec 2021 00:00:00 +0100 from the Swedish Energy Agency to Chalmers centers<p><b>​When the Swedish Energy Agency distributes SEK 600 million to eleven different competence centers for sustainable energy systems, Chalmers is behind more than half of the centers that are granted funding.

This is the focus of Patrik Johansson's research project, which has been granted funding within the Swedish Research Council's Distinguished Professor Programme. The grant of 47.5 million SEK extends over a ten-year period.“The long time span opens up for greater risk-taking and provides the opportunity to work long-term. These are highly important factors for conducting research,” says Patrik Johansson.</b></p><div><strong>Patrik Johansson</strong> is professor at the Department of Physics and one of Sweden's most prominent battery researchers. His focus is on exploring new concepts and solutions for batteries – and that is also what he will do within the context of the Swedish Research Council’s Distinguished Professor Programme.</div> <div><br /></div> <div>The extensive grant means that he, as research leader, can build on already existing projects within his research group, but also explore new possibilities within the framework of what the project's title signals: the next generation of batteries.</div> <div><br /></div> <div>“As a battery researcher it can be easy to just look at the products that exist already today, and thus productize your thinking, especially due to the great interest in society for the ongoing electrification of everything and anything. Your focus turns to short term solutions, in order to help different actors solve whatever problems they are having here and now. That is of course something that has to be done – but as a researcher you also have a responsibility to resist this way of acting and focus on finding concepts that are favourable in a longer time perspective – more of revolution than evolution, says Patrik Johansson.</div> <div><br /></div> <div>“The grant gives me the opportunity to try a lot of fundamentally different things, which you may not always be able to say later on that you have &quot;succeeded with&quot;, but which you in turn learned all the more from and which have been really challenging. And that is successful in itself; discovering the concept space is probably just as important. A special driving force for me personally is to try to get the research group to get far with small and simple ideas – quite challenging today when a lot of research is made large and complicated. The grant is also important to me as a research leader to build our operation, to lead it forward strategically, and to plan for what competencies are needed for a broader and at the same time deeper scope. However, my research <em>itself </em>has not in any way improved by me getting a distinguished professor grant, says Patrik Johansson with a laugh.</div> <div><br /></div> <div style="font-size:20px">Batteries that meet the energy needs of the future</div> <div><br /></div> <div>The battery that is in vogue today is without a doubt the lithium-ion battery, which is found in everything from mobile phones to electric cars and electric ferries. But to meet the mobile and also stationary needs of the future for energy storage in the best way – readily available energy with high quality – large electrochemical energy storage solutions, i.e. batteries, will be needed. Here Patrik Johansson sees that we need to think afresh; perhaps create new types of batteries based on more common metals, such as sodium, calcium or aluminium? Or organic batteries?</div> <div><br /></div> <div>“Today, electrification is being built up in a lot of different sectors and everything is based on lithium-ion batteries. We already see this year that the price of lithium-ion batteries, which has fallen sharply for a long time, is now levelling out. In the long run, it's probably about sustainability. If you can then launch one or more complementary battery technologies that are cheaper, safer, or simply just different – there may be advantages for a battery to for example work at 80 rather than 25 degrees Celsius – there is much to be gained. Today battery researchers in general are not looking in that direction, which my research group will now do. Concept creation is always based on fundamental material physics, but also requires great methodological knowledge and application understanding, says Patrik Johansson.</div> <div><span style="background-color:initial"><br /></span></div> <div style="font-size:20px"><span style="background-color:initial">Conceptually different batteries</span></div> <div><br /></div> <div>Battery research is a field that is developing rapidly. What was in vogue five years ago has already passed in many ways, in terms of exploration of materials, methods and concepts. Likewise, society's needs are changing at a rapid pace – ten years ago there was hardly any talk of electric cars or electric aircraft, today the issue of electrification is dominant in the development of society. So where are we in 2030, to which is the year the Distinguished Professor Programme extends?</div> <div><span style="background-color:initial"><br /></span></div> <div><span style="background-color:initial">“It is of course very difficult to predict, but what we want for 2030 is something that is conceptually different and not just a refinement of existing technology. Whether that change then may be at the battery, material or functionality level – so be it. What I wish us to have achieved in ten years' time is that we have found two or three new concepts that hold up to a critical examination and at least have the potential to complete the step from research to technology.

The aim of the research program is to create the conditions for a sustainable society by researching next generation of ecofriendly materials and manufacturing processes. This will also facilitate better technology for energy systems of the future, and to combat pollution and toxic emissions.<br /><br />In parallel with this funding, the Wallenberg Wood Science Center, which was established in 2009 with the aim of developing new innovative materials from the Swedish forest, will receive an increased grant of SEK 380 million.<br /><br />“It is incredibly exciting that KAW has chosen to invest in sustainable materials science in this forward-looking way. Chalmers has long conducted outstanding research in this area, and we will be able to contribute to the new initiative with a broad knowledge base. We will be able to take advantage of the new opportunities and strengthen our national collaborations and contribute to strengthening Sweden as an advanced materials development nation together with our strategic partners in the field,” says Anders Palmqvist, vice president for research and professor of materials chemistry, at Chalmers.<br /><div><br /></div> <div><h2 class="chalmersElement-H2">Wallenberg Initiative Material Science for Sustainability</h2> <div>Every year a vast quantity of raw materials is extracted across the world. These are mainly metals, minerals, fossil fuels and biomass. Today most of the extracted materials are non-renewable, placing a heavy burden on the environment, societies, and climate. Global production of materials accounts for a large proportion of the total emissions of greenhouse gases, and the production of metals requires a lot of energy.</div> <div> </div> <div>To meet these challenges, the Wallenberg Initiative Material Science for Sustainability research program focuses on four areas: conversion, storage and distribution of clean energy; circular materials replacing rare, energy-demanding, and hazardous materials; mitigation, cleaning and protection of atmosphere, soil, and water and discovery of materials for novel sustainable technologies.</div> <div> </div> <div>“To meet climate and environmental targets industry needs to transition towards sustainability at a swifter rate. For this reason, the research program will be conducted in collaboration with Swedish industry in the form of industrial PhDs and postdocs, and also via research arenas allowing an exchange of knowledge and problems between academia and private enterprises. Industry acquires knowledge generated by research in materials science, and researchers gain insights into the technological and application challenges faced by companies,” says Sara Mazur, director strategic research at Knut and Alice Wallenberg Foundation, and chair of the program.</div> <div> </div> <div>“We aspire to establish Sweden as a leading nation in this research field.

The properties of the latest solar cell car were recently tested in the Solar Challenge Morocco competition.</b></p><div>​Chalmers Solar Team competed in 2019 for the first time in what is called the world's largest solar cell car competition, The Bridgestone World Solar Challenge. The basic idea of the competition is to push the technological boundaries of what can be done with solar power. The World Solar Challenge, which takes place every two years, had to be canceled this year due to the pandemic. Instead, an alternative race called Solar Challenge Morocco was arranged. Each team had to drive 250 km on public roads divided into five days. The goal was to get to the finish line as quickly as possible only with the help of energy from solar cells mounted on the car. Except for a smaller battery that was used in the start.</div> <div><br /></div> <div> </div> <div><img src="/SiteCollectionImages/Institutioner/IMS/IMS/Solbil_06.jpg" alt="Solar cell car" class="chalmersPosition-FloatLeft" style="margin:5px 15px;width:335px;height:444px" />Six teams competed against each other in the same class as Chalmers, which this year lined up with a new car. All the teams managed to reach the finish line, which was an achievement in itself as many teams in previous competitions had to give up. In addition to being able to get around with only solar energy, the car must also withstand sometimes quite tough conditions in the form of heat, wind and often hilly and bad roads. Chalmers placed sixth in the competition, but the conditions for the different teams have also been very different. Many of the teams have been in place for many years and the economic conditions have not been equal.</div> <div><br /></div> <div> </div> <div>“We have built the solar cell car at Chalmers almost entirely ourselves with relatively small funds in just over a year. That we have designed, constructed and managed so much on our own is a big difference compared to the other teams. So, we are very satisfied with our efforts, says Alexander Andersson who is currently studying his master's.”</div> <div> </div> <div>Getting through Morocco's barren desert landscape was an adventure. For example, some of the cold desert nights were spent on blankets outdoors. One of the days the solar cell car stopped, and it took a few hours of troubleshooting before the problem could be fixed. It turned out that there was a loose electrical connection, probably due to the somewhat bumpy road. The entire team was also involved in the strategy while driving as energy data could be monitored continuously from the accompanying cars. For example, drivers could be instructed to adjust the speed for certain distances to avoid clouds and maximize solar energy. The top speed for Chalmers car was around 100 kilometers per hour and for the best team about 140 kilometers per hour. Each driver team consisted of three people who took turns driving, plus two reserve drivers.</div> <div>Even though it was a competition, and there was a battle to win, the atmosphere between the teams was all and all familiar and helpful.</div> <div><br /></div> <div><img src="/SiteCollectionImages/Institutioner/IMS/IMS/Solbil_03.jpg" alt="Solar cell car" style="margin:5px" /><br /><br /><br /></div> <div> </div> <div>&quot;Yes, in case of problems, we helped each other, and we shared some ideas between each other. For example, many wanted to know more about the material in our specially built body. But some things were kept more secret, such as electrical systems for example, says Alexander Andersson.&quot;</div> <div> </div> <h2 class="chalmersElement-H2">Unique car body in natural fiber</h2> <div><img src="/SiteCollectionImages/Institutioner/IMS/IMS/Solbil_07.jpg" alt="Solar cell car" style="margin:5px" /><br /><br />Chalmers solar cell car is built on a steel frame with a body made of flax fiber, and weighs about 200 kg. The choice of flax fiber also attracted a lot of attention as all the competitors' cars were built in carbon fiber. A material that admittedly has good properties but also has a higher environmental impact. Chalmers solar team's goal was to build as environmentally friendly as possible and the choice then fell on flax, which is a type of natural fiber. The lighter the car the better, but the difference in weight was not estimated to be so decisive that carbon fiber was needed. Aerodynamics and the electrical system were considered to be more important for performance, which was something that the team hope to be able to improve for the next competition. The capacity of the solar cells is 800 watts.</div> <div> </div> <h2 class="chalmersElement-H2">Many different skills required</h2> <div>Chalmers Solar Team consists of people with a background from many different educational programs at Chalmers because there are many pieces that will fit. It is a comprehensive project that is not just about building the solar cell car. A large part is about managing contacts with sponsors and managing logistics and media.</div> <div><br /></div> <div> </div> <div>&quot;It has really been a very fun and educational project to be involved in. What we have learned in the courses at Chalmers has really come in handy. You also get to know people in a completely different way compared to regular project work, and everything you do is real, says Caroline Reinisch, who is studying her second year at Chalmers.&quot;</div> <div> <img src="/SiteCollectionImages/Institutioner/IMS/IMS/Solbil_02.png" alt="Solar cell car" style="margin:5px" /><br /><br /></div> <div>The team will probably continue to work with the same concept before the next competition, depending on what the rules look like. It is hoped to be able to work more with simulations and expand the team and the structure around the team. Anyone who is interested and wants to know more can contact Chalmers Solar Team via their Facebook page.</div> <div><h2 class="chalmersElement-H2">Support</h2></div> <div>Chalmers Solar Team is a student association that was started with the help of Göran Gustafsson, senior lecturer at the Department of Industrial and Materials Science at Chalmers. The Department of Industrial and Materials Science has also provided financial and administrative support.<br /><br />&quot;Chalmers has been our greatest strength and what made the project possible.

Through these collaborations I have learned about some of the challenges the industry is having in improving their production.”</p> <div> </div> <p class="chalmersElement-P"><em>Text:</em> Susanne Nilsson Lindh<br /><em>Photo:</em> Johan Bodell</p> <p class="chalmersElement-P"><br /></p> <p class="chalmersElement-P"><strong>Read more about:</strong> <a href="">Highly CIted Researchers</a></p> <div> </div> <p class="chalmersElement-P"><span><strong>Read more about</strong><a href="/en/Staff/Pages/Jens-B-Nielsen.aspx"><strong> Jens Nielsen</strong></a><strong> and his research:</strong></span></p> <p class="chalmersElement-P"></p> <ul><li><p class="chalmersElement-P"><span><a href="/en/departments/bio/news/Pages/Designing-healthy-diets-–-with-computer-analysis.aspx">Designing healthy diets – with computer analysis</a></span></p></li> <p class="chalmersElement-P"> </p> <li><p class="chalmersElement-P"><span><a href="/en/departments/bio/news/Pages/Designing-healthy-diets-–-with-computer-analysis.aspx"></a><span></span><a href="/en/departments/bio/news/Pages/The-next-generation-of-human-metabolic-modelling.aspx">The next generation of human metabolic modelling​</a><br /></span></p></li> <p class="chalmersElement-P"> </p> <li><p class="chalmersElement-P"></p> <div><p><a href="/en/departments/bio/news/Pages/Yeast-can-be-engineered-to-create-protein-pharmaceuticals.aspx">Yeast can be engineered to create protein pharmaceuticals</a></p></div> <p></p></li> <p class="chalmersElement-P"> </p> <li><p></p> <p class="chalmersElement-P"><a href="/en/departments/bio/news/Pages/Improved-cellfactories.aspx">Exhale – improved cellfactories in sight​​</a></p> <p></p></li></ul> <p></p> <p class="chalmersElement-P"><br /></p>Thu, 18 Nov 2021 13:00:00 +0100 pioneer honoured by scientific journal<p><b>​The prestigious scientific journal Energy &amp; Fuels is dedicating a special issue to Anders Lyngfelt, professor of energy technology at Chalmers, in their series Pioneers in Energy Research. Anders has been chosen for his leading research on chemical looping combustion, a technology that is both very energy efficient and makes carbon capture simple and cheap.– I am glad to see an increasing interest in capturing carbon and a growing insight that it is one of the tools we must start using on a large scale. We need to do EVERYTHING, turn every stone, both to quickly reduce emissions and to capture carbon dioxide from the atmosphere with negative emissions, says Anders Lyngfelt.</b></p>​<span style="background-color:initial">Energy &amp; Fuels has been published since 1978 and as the name suggests, the content spans broad research areas related to energy and fuels. Anders is one of Chalmers and Sweden's most cited researchers and has been published in Energy &amp; Fuels about 40 times. He is the fourth researcher in the magazine's series on Pioneers in Energy Research, the previous three work in solar energy, crude oil and bioenergy and fuels. </span><div><br /></div> <div>– It feels great! In addition to me getting this acknowledgement, I enjoy the fact that our research area gets attention. Energy &amp; Fuels is definitely a significant and serious magazine, with a good impact factor.</div> <div>That Anders - and his research colleagues - are getting this honor is because they have led the development of the technology chemical looping combustion for a long time. It is an efficient combustion technology that makes it possible to easily and cheaply collect the carbon dioxide created during combustion, for further storage. </div> <div><br /></div> <div>Capturing and storing carbon dioxide is becoming an increasingly interesting method of reducing global warming. But the flue gases from conventional combustion - to produce district heating and electricity, for example - contain only about 15 percent carbon dioxide and separating it is expensive and also costs a lot of the energy that would go to producing district heating and electricity.</div> <div><br /></div> <div>– That is why carbon dioxide capture is only available at two power plants in the world today. But with chemical looping combustion, there is no need for the complicated gas separation. Ideally, in addition to water vapor, it is pure carbon dioxide that comes out of the chimney, ready for storage.</div> <div><br /></div> <div>Although Anders and chemical looping combustion are now being featured in Energy &amp; Fuels, the technology is not used anywhere in the industry today. This is largely due to the fact that today there is already existing technology for combustion and that there is not strong enough pressure on the industry to collect carbon dioxide. But now that interest in carbon capture and storage is increasing, so is interest in chemical looping combustion. And the technology can make a big contribution, Anders believes.</div> <div><br /></div> <div>– The so called carbon dioxide budget, the amount of carbon dioxide that can be released into the atmosphere without us exceeding the target of 1.5 degrees temperature increase, I likely to be finished in 2028 at the rate we are keeping today.</div> <div><span style="background-color:initial"><br /></span></div> <div><span style="background-color:initial">–</span><span style="background-color:initial"> </span>No matter how optimistic your calculations are, no one believes that we will stop emitting carbon dioxide in seven years - so all emissions after 2028 must be removed from the atmosphere with so-called negative emissions. Here, chemical looping combustion can be very useful.</div> <div><br /></div> <div>One area of use that may be relevant is BECCS, Bio-Energy with Carbon Capture and Storage. Carbon dioxide is then collected at, for example, bio-fired power plants to achieve a net reduction of carbon dioxide in the atmosphere. Anders is one of the organizers behind next year's conference on negative emissions, the second in a series of conferences that will increase knowledge about the various possibilities that exist for achieving negative emissions.</div> <div><br /></div> <div>Anders now hopes that Sweden - from which the development of the technology has been led for many years - will be the first country where the technology is used on an industrial scale.</div> <div><span style="background-color:initial"><br /></span></div> <div><span style="background-color:initial">–</span><span style="background-color:initial"> </span>My main focus right now is to get someone to dare take the step and use this technology.

The project, conducted by a consortium of 20 industrial and research partners from 11 countries, aims to demonstrate a new path to create value from industrial CO2 emissions – while improving the sustainability of the chemical industry in Europe.<br /><br />The scope is to establish and demonstrate an innovative platform for carbon capture and utilization, CCU, that turns industrial CO2 into chemical building-blocks using a new biotechnological approach. These are then converted further catalytically into a wide range of products, including other value-added chemicals such as components for paints and plastic, synthetic fuels, as well as recyclable or biodegradable materials normally produced from fossil hydrocarbons. <br /><br />&quot;The project develops a biotechnological process in which industrial CO2 emissions, such as from cement production, is used to produce chemicals. Not only does it contribute to decreasing the emission of CO2. In doing so, it converts the CO2 into chemicals which would otherwise most likely be produced using fossil resources,&quot; explains Senior Researcher Matty Janssen at Chalmers University of Technology in Gothenburg.<br /><br /></div> <div>Chalmers’ role in the project is to guide the process developers to make design choices for a more environmentally benign design.

But after analysing the growth rates of wind and solar power in 60 countries, researchers at Chalmers, Lund University and Central European University in Vienna, Austria conclude that virtually no country is moving sufficiently fast to avoid global warming of 1.5°C or even 2°C. </b></p>&quot;This is the first time that the maximum growth rate in individual countries has been accurately measured, and it shows the enormous scale of the challenge of replacing traditional energy sources with renewables, as well as the need to explore diverse technologies and scenarios&quot;, says Jessica Jewell, Associate Professor in Energy Transitions at Chalmers University of Technology.​<div><br /></div> <div>​The Intergovernmental Panel on Climate Change (IPCC) has identified energy scenarios compatible with keeping global warming under 1.5°C or 2°C. Most of these scenarios envision very rapid growth of renewable electricity: on average   about 1.4 per cent of total global electricity supply per year for both wind and solar power, and over 3 per cent in more ambitious solar power scenarios. But the researchers’ new findings show that achieving such rapid growth has so far only been possible for a few countries.  <div><br /></div> <div><span style="background-color:initial">Measuring and predicting the growth of new technologies like renewable energy is difficult, as they do not grow linearly. Instead, the growth usually follows a so-called S-curve. This means that when production of wind or solar power begins in a country it first accelerates exponentially, then stabilizes to linear growth for a while, and in the end slows down as the market becomes saturated.</span></div> <div><span style="background-color:initial"><br /></span></div> <div><img src="/SiteCollectionImages/Institutioner/SEE/Nyheter/Jessica-Jewell-200.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px" />&quot;Scholars typically assess technological growth by measuring how fast a given technology reaches market saturation. But for wind and solar power this method does not work, because we don’t know when and at what levels they will saturate. We came up with a new method: to use mathematical models to measure the slope of the S-curve, i.e. the maximum growth rate achieved at its steepest point. It is an entirely novel way to look at the growth of new technologies&quot;, says Jessica Jewell. </div> <h3 class="chalmersElement-H3">Analysis of 60 countries</h3> <div>The researchers use these mathematical models to estimate the maximum growth rates achieved in the 60 largest countries which together produce ca 95% of the world’s electricity. They show that the average rate of onshore wind power growth achieved at the steepest point of the S-curves is 0.8% (with half of the countries falling within the 0.6-1.1% range) of the total electricity supply per year. For solar power, these estimates are somewhat lower: 0.6% on average (range 0.4-0.9%). </div> <div><br /></div> <div><span style="background-color:initial">Higher rates, comparable to those required in climate scenarios, are indeed sometimes achieved, but typically in smaller countries. For example, wind power in Ireland expanded at some 2.6% per year while solar power in Chile has grown at 1.8% per year. However, fast growth is much rarer in larger countries. Among larger countries, only Germany has so far been able to sustain growth of wind power comparable with median climate scenarios (above 1.5% per year). </span><br /></div> <div><br /></div> <div><img src="/SiteCollectionImages/Institutioner/SEE/Nyheter/Aleh-Cherp-200.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px" />&quot;In other words, to stay on track for climate targets, the whole world should build wind power as fast as Germany has recently&quot; says Aleh Cherp, a professor in Environmental Sciences and Policy at Central European University and Lund University. </div> <div><br /></div> <div>(As a side-note, Sweden has been growing wind power (including offshore) at about 1.6% per year in the last decade but this is at the upper end of the growth we observed in other countries.)</div> <h3 class="chalmersElement-H3"><span>​Why late adopter grow equally slow</span></h3> <p class="chalmersElement-P"><span>To investigate future prospects of ren</span><span>ewables, the researchers have also compared th</span><span>eir growth in the pioneering countries (mostly in the European Union and other high-income industrialised nations) and in the rest of the world, where solar and wind power were introduced later. </span><span>The</span><span> latter group</span><span> includes most developing and emerging economies that would be responsible for the bulk of global energy use and thus need to deploy most of wind and solar power in the 21st century. It is hypothetically p</span><span>ossible that these countries could skip the trial-and-error stage which slowed down the early adopters, and thus leapfrog to higher growth rates. Unfortunately, the researchers discover that this is not the case. ​</span></p> <p class="chalmersElement-P"><span><br /></span></p> <div>&quot;There are usually reasons why they are late to enter the race. It can be because of vested interests, weaker institutions, and an investment environment that doesn’t support new technologies as well as from unsuitable geography. Those reasons have prevented renewable energy from taking off in the first place and make it especially difficult to replicate or exceed the growth rates achieved in leaders. Thus, we cannot automatically assume that the countries which introduce wind and solar power later would learn from prior experience and grow these technologies faster&quot;, says Cherp.</div> <h3 class="chalmersElement-H3">Challenges for policy makers</h3> <div>The study highlights several policy challenges. One is for high-income countries to avoid the slowdown of solar and wind expansion, recently observed in several places. Another is for major Asian economies such as India and China to increase the growth rates so that renewables start growing faster than electricity demand and eventually push out fossil fuels. This can be achieved by widening the cost gap between renewables and the fossils, which include subsidies, phasing out or taxing competing technologies and supporting grid integration. </div> <div>&quot;Finally, we should recognize that there may be natural limits to how fast wind and solar can be expanded and thus we should systematically investigate the feasibility of other climate solutions&quot;, says Cherp.</div> <div><br /></div> <div><em>Text: Christian Löwhagen</em></div> <div><em>Image credits: Main photo: Pixabay. Jessica Jewell: Udo Schlög.
