Energy Combine

A rapid introduction of biomass-based energy combines presents major challenges for technology development throughout the production chain, from feedstock to final products and for appropriate integration of the plants in the energy system.

Important industrial and societal problems for the development of Energy Combines and being discussed in collaboration projects are:

  • Large-scale build-up must occur rapidly despite substantial knowledge gaps throughout the whole production chain from biomass feedstock to final products, i.e. implementation is not dependent on breakthrough for one single bottleneck technology.
  • Optimal combinations of technologies, process routes and product mixes must be identified in order to attract investor capital. 
  • Energy combines must fit into the overall energy system and the consequences of existing and possible future policy instruments need to be understood.


Research packages

The research within Energy Combines is focused to three areas; Thermochemical conversion of biomass, Chemical and biochemical conversion of biomass, and Process integration.

Thermochemical conversion of biomass comprises biomass gasification and large scale electricity biomass based electricity generation. The overall aim of the research in this area is three-fold:

  • To develop knowledge and methods which make it possible to produce a gas from biomass gasification that meets the requirement of downstream processes,
  • To search for optimal ways to burn difficult fuels and fuel mixtures, with low emissions and without alkali-related fireside corrosion and,
  • To find new processes for increasing the use of biomass in thermal power generation.

The research tasks within Chemical and biochemical conversion of biomass aim to develop the lingo-cellulosic-based process industry. One objective is to partly transform today’s chemical pulp mills into energy combines for the production of fuels and products. Another objective is to develop novel process solutions for different types of process industry, which can meet requirements for a drastically changed product mix.

The vision for Process integration is to considerably improve the knowledge of system aspects (energy efficiency, integration with process plants, yield increase, greenhouse gas mitigation, etc. technically and economically) of energy combines, especially different concepts for biorefineries in process industries and/or large district heating systems. Industries of interest are the pulp and paper, oil refinery, chemical/petrochemical and food industries.
