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.

Researchers develop highly efficient organometal halide perovskite photoelectrodes for water splitting

Green Car Congress

Photoelectrochemical (PEC) water splitting based on solar energy is one promising approach for the production of green hydrogen. However, its widespread application is limited by a lack of efficient photoanodes for catalyzing the rate-limiting oxygen evolution reaction (OER), an important reaction in PEC water splitting.

Sparc Hydrogen to test photocatalytic water splitting (PWS) reactor at CSIRO

Green Car Congress

The Sparc Green Hydrogen process combines concentrated solar (CS) with photocatalytic water splitting. The company’s key development allows for reduced photocatalyst use and integration with existing concentrated solar systems. The facility is home to Australia’s largest solar thermal research hub.

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

Green Car Congress

Researchers in Europe led by a team from ETH Zurich have designed a fuel production system that uses water, CO 2 , and sunlight to produce aviation fuel. 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. Zoller et al.
