EPFL solar hydrogen system co-generates heat and oxygen

Green Car Congress

EPFL researchers have built a pilot-scale solar reactor that produces usable heat and oxygen, in addition to generating hydrogen with unprecedented efficiency for its size. This is the first system-level demonstration of solar hydrogen generation. Resources Holmes-Gentle, I., Tembhurne, S.,

Synhelion starts construction of DAWN demo plant to produce solar fuels

Green Car Congress

ETH Zurich spin-off Synhelion has started the construction of DAWN—its own industrial plant to produce synthetic fuels using solar heat. The production process—using only solar heat—was first demonstrated in 2019 in a mini-refinery on the roof of ETH Zurich. Earlier post.)

All-in-one solar-powered tower makes carbon-neutral kerosene in the field at pilot-scale

Green Car Congress

We are the first to demonstrate the entire thermochemical process chain from water and CO 2 to kerosene in a fully-integrated solar tower system. Previous attempts to produce aviation fuels through the use of solar energy have mostly been performed in the laboratory. B) Photograph of the solar tower fuel plant during operation.

Wärtsilä gas engines to burn 100% hydrogen

Green Car Congress

The technology group Wärtsilä is developing the combustion process in its gas engines to enable them to burn 100% hydrogen fuel. Wärtsilä has researched hydrogen as a fuel for 20 years, and has tested its engines with blends of up to 60% hydrogen and 40% natural gas. Hydrogen as part of the renewable electricity system of the future.
