Bioenergy: Strategic energy for a fossil-free future
Bioenergy is energy generated from organic matter (biomass), such as wood residues, manure, sewage sludge, and organic waste. Where solar and wind power sources are variable, bioenergy offers a stable and controllable basis. In the current energy transition, the role of bioenergy is shifting: from large-scale electricity generation to targeted use in heavy industry, transport, and the production of renewable gas.
Conversion Techniques and Products
Depending on the biomass used and the chosen technique, different energy carriers are created:
-
Combustion: Direct conversion to bio-heat for industrial processes and district heating networks. In combination with CO2 capture (BECCS), this can even lead to 'negative emissions'.
-
Anaerobic digestion: Microorganisms convert wet residual streams (such as manure and sewage sludge) into biogas . This is increasingly being upgraded to green gas , which can be fed directly into the existing natural gas grid.
-
Gasification and Pyrolysis: By converting biomass at high temperatures, synthesis gas or bio-oil is produced . These serve as the basis for advanced biofuels (HVO, SAF) for aviation and maritime transport.
The new role of Bioenergy
Bioenergy is prioritized where no alternatives exist. We use it for high-temperature heat in industry and as a fuel for long-distance heavy transport. This way, bioenergy contributes significantly to saving fossil fuels and stabilizing our energy grid.
