EU project HyFlexFuel converted sewage sludge and other biomasses into kerosene by hydrothermal liquefaction (HTL); SAF

Green Car Congress

The decarbonization of the transportation sector will require large volumes of renewable fuels. So far, renewable diesel and jet fuels are mainly derived from plant oils, but the EU Renewable Energy Directive limits the use of biofuel from food and feed crops since they do not meet sustainability requirements when produced at large scale.

Empa researchers investigating new process for production of synthetic methane

Green Car Congress

Such fuels, produced synthetically with renewable energy, can be transported via conventional routes and made available through the existing infrastructure. Methanization works by producing methane (CH 4 ) and water (H 2 O) by catalytic conversion from carbon dioxide (CO 2 ) and hydrogen (H 2 ).

“Energiewende” in a tank; Audi e-fuels targeting carbon-neutral driving with synthetic fuels from renewables, H2O and CO2; Swiss policy test case

Green Car Congress

Audi’s basic goal is to combine renewable energy (e.g. solar and wind), water and CO 2 to produce liquid or gaseous fuels with a very low carbon intensity. to the realization of the renewable energy + water + CO 2 formula. The Audi e-gas plant can convert 6MW of input power. Earlier post.)

EPFL team develops low-cost water splitting cell with solar-to-hydrogen efficiency of 12.3%

Green Car Congress

Michael Grätzel at EPFL (Ecole Polytechnique Fédérale de Lausanne) in Switzerland has developed a highly efficient and low-cost water-splitting cell combining an advanced perovskite tandem solar cell and a bi-functional Earth-abundant catalyst. Splitting water requires an applied voltage of at least 1.23 Credit: EPFL.
