Bio-electro-fuels - technology for higher resource efficiency
Use of electrical energy in biofuel production can give large benefits through improved production potential, resource efficiency and sustainability. This is achieved by reducing biogenic carbon losses or the use of natural gas.
The supply of electrical energy to biofuel production processes can potentially provide major benefits by being an effective way to increase production potential, resource efficiency and sustainability. Partial electrification of these processes can thus make a significant contribution to the transformation of the transport sector. The resulting fuel products can be called bio-electro fuels, as they have energy contributions from both biomass and renewable electricity, while the carbon atoms in the fuels produced come exclusively from the bio-raw material. It is important to distinguish this from pure electric fuels that only take energy from electricity and where carbon dioxide is used as a carbon source.
Different technical solutions are relevant for different production routes, but heating and electrolysis of carbon dioxide or water are important alternatives. The project provides an overall picture of technical possibilities as well as advantages and disadvantages of the technology. This is done through studies of a number of value chains and quantification of effects on sustainability, costs and yields. Technical results are synthesized and aggregated in a scenario work to study the technology's production potential and interaction with the electrical system. The consortium contains commercial representatives from the entire value chain.
