Highly efficient and flexible integration of biomass and renewable hydrogen

Bio-FlexGen will increase the efficiency and flexibility of renewable heat and power, which thereby may become an important part of a future energy system with intermittent solar and wind power. In this way Bio-FlexGen contributes to a fossil-free energy system.

Climate change is the most significant challenge for humanity today. For this reason, fossil fuels must be replaced
utilising renewables, improved energy efficiency and more flexible energy systems. An optimal combination of
several renewable sources is needed to satisfy society’s energy needs. Bioenergy, in combination with hydrogen,
can take a key role as a secure and plannable source for power and heat complementing intermittent renewable
sources such as wind and solar power.

Bio-FlexGen will increase the efficiency and flexibility in renewable heat and power, and thereby contribute to the decarbonisation of the energy system. In Bio-FlexGen will be developed a unique combination of gasification and turbine technique that uses hydrogen to produce power when the demand increases fast, and biomass to keep down production costs. Because of the high efficiency, three times more power can be generated compared with conventional combined heat and power at a given heat production. Full load can be reached rapidly by starting on hydrogen. Fluctuating demand and price can be met by production of green hydrogen e.g. during periods of low electricity price

Bio-FlexGen summons the necessary expertise and experience in terms of four universities, two research institutes, one non-governmental organisation and four industry companies, distributed over five countries in EU.
