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. Holmes-Gentle et al.

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.

Photocatalytic optical fibers convert water into hydrogen

Green Car Congress

Researchers at the University of Southampton have transformed optical fibers into photocatalytic microreactors that convert water into hydrogen fuel using solar energy. Alongside hydrogen generation from water, the multi-disciplinary research team is investigating photochemical conversion of carbon dioxide into synthetic fuel.

Monash study on solar-driven electrolysis for green hydrogen production cautions on life-cycle emissions and EROI

Green Car Congress

Researchers at Monash University in Australia have conducted a lifecycle analysis and net energy analysis (LCA/NEA) of a hypothetical large-scale solar-electrolysis plant for the production of green hydrogen. of hydrogen is currently produced via water electrolysis and only a fraction of this production is powered by renewable energy.

Heliogen and Bloom Energy demonstrate production of low-cost green hydrogen; concentrated solar and high-temp electrolysis

Green Car Congress

Heliogen and Bloom Energy have successfully demonstrated the production of green hydrogen by integrating the companies’ technologies: Heliogen’s concentrated solar energy system and the Bloom Electrolyzer. Because it operates at high temperatures, the Bloom Electrolyzer requires less energy to break up water molecules and produce hydrogen.

Audi Hungaria starts operation of Europe’s biggest solar roof installation

Green Car Congress

Audi Hungaria is thus the second of five Audi sites (after Audi Brussels) to achieve a neutral carbon balance, according to the company. We have a clear aim: that all Audi sites will have carbon-neutral operation by 2025. The remaining heat is generated through natural gas, with carbon neutrality assured thanks to bio-gas certificates.
