​The R&D strategy of DONG Energy within power plant technology has great emphasis on using renewable and CO2-neutral bioresources as fuel in existing and new plants. This creates the need for also utilising new types of such bio resources available in large amounts and being less expensive. DONG Energy is a large and professional company with many competences within the whole chain of work covered by this project. By undertaking a leading role in this project, DONG Energy intends to contribute to the planned demonstration and further commercialisation of the Low Temperature Circulating Fluidized Bed technology. DONG Energy has followed the Low Temperature Gasification process from the beginning (through Elsam Engineering) and contributed to the development of the process.

​Since 1995, DFBT, at first as a consultancy, participated in various R&D projects led by mainly Risø and DTU. The basis for this was 15 years of professional experiences gained primarily from Peder Stoholms work at mainly Risø National Laboratory. Then DFBT developed the ideas for the LT-CFB technology and since ie, over a decade now, DFBT headed the multi partner R&D work which brought the LT-CFB technology to its now very promising and still developing status, where large-scale demonstration and similarly ramped up financial resources are needed to quickly realise the technology's great potential on a now severely needing world marked.


​Strong emphasis is laid on research and development. Innovative concepts and technological expertise coupled with over 90 years of experience in the refractory industry ensure the continuous development of products and services. Calderys is a 100% owned subsidiary of IMERYS, the world leader in the supply of raw materials to the refractory industry. This provides reliable access to high-quality raw materials which is an essential prerequisite for R&D activities as well as the production. The refractory is identified to be a key component within the gasifier, and refractory competences are limited within DONG Energy. Hence it is very important having Calderys as part of the consortium to develop a robust solution.


Main activities are the corresponding mathematical modelling as well as experimental testing and optimisation. Due to being part of the Danish Technical University, the Biomass Gasification Group has great access to students at up to PhD level, whom to a large extend are involved in and contributes to the ongoing work.


​CHEC has achieved international recognition through a combination of experiments and modelling. Laboratory experiments provide detailed and accurate data for the systems studied. The data are subsequently interpreted eg, by application of mathematical modelling based on chemical kinetics, chemical reaction engineering, thermodynamics, and fluid dynamics. The models are often validated by pilot-scale and/or full-scale tests. CHEC has several years of experience with high-temperature global equilibrium simulations on solid fuel conversion systems as well as with developing (sub)models for homogeneous nucleation of vapour phase inorganic species, formation of residual ash by mineral coalescence and fragmentation, transport of ash species (diffusion, thermophoresis and inertial impaction) as well as initialisation, build-up, sintering and shedding of ash deposits.

​Previously the research group investigated the availability of P and K in ash from gasification of animal manure in an LT-CFB plant. This work was made in collaboration with DFBT. The department has comprehensive experience in experimental work in soil-plant systems. For a number of years, the “Farming System Unit” has been working with life cycle assessment (LCA) methodologies in relation to agricultural production, including also the production and use of bioenergy.
