The use of regeneratively produced fuels (reFuels) is a promising path towards CO2-neutral mobility, alongside other measures such as the expansion of electric mobility. These fuels can be produced from carbon-containing residues from agriculture and forestry, from industrial and municipal waste, as well as from CO2 in combination with hydrogen obtained by electrolysis of water. These fuels together form the reFuels class. In order to assess the potential of reFuels, a holistic evaluation is necessary, including the determination of efficiency potentials for their manufacture and application. Under the patronage of the state of Baden-Württemberg the technology partnership reFuels was initiated, in which companies of the energy and mineral oil industry, the automotive industry and the supplier industry together with the Karlsruhe Institute of Technology (KIT) are investigating efficiency potentials for the production and application of reFuels. Pilot facilities already in operation will be used to produce fuel components in a sufficient scale. The systemic and socioeconomic aspects for the production and application of reFuels will be considered and put in an dialogue with civil society actors to consider the open communication into society.. ... mehrWithin the reFuels project started in 2019 for 2 years duration the consortium of industrial companies and KIT including companies as energy providers, fuels synthesis to suppliers, system developers to engine and car manufacturers. The Project shall achieve the following goals: 1. Provision of selected regenerative fuels ("reFuels") and holistic evaluation of the processes for their production including the determination of efficiency potentials for production and application 2. Evaluation of reFuels key properties, demonstration in the application and evaluation of the application properties 3. Involvement of civil society actors and communication in society.
