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.

NREL scientists advance solar thermochemical hydrogen (STCH) production

Green Car Congress

The NREL scientists analyzed solar thermochemical hydrogen (STCH) production, which can be potentially more energy-efficient than producing hydrogen via the commonly used electrolysis method. Electrolysis needs electricity to split water into hydrogen and oxygen. A conceptual solar thermochemical hydrogen production platform.

Toyota and DIFFER partner on direct solar production of hydrogen from humid air, rather than water

Green Car Congress

The Dutch Institute for Fundamental Energy Research ( DIFFER ) is partnering with Toyota Motor Europe (TME) to develop a device that absorbs water vapor, and splits it into hydrogen and oxygen directly using solar energy. In this project, DIFFER and TME are exploring an innovative way to produce hydrogen directly out of humid air.

Study finds direct seawater splitting has substantial drawbacks to conventional water splitting, offers almost no advantage

Green Car Congress

A study by a team of researchers from Technische Universität Berlin (TUB) and Fritz-Haber-Institut der Max-Planck-Gesellschaft has found that direct seawater splitting for hydrogen production has substantial drawbacks compared to conventional water splitting and offers almost no advantage. Additionally, H 2 O is needed for water splitting.

Roskill: concerns over water consumption exposes lithium brine producers to ESG risk

Green Car Congress

One environmental concern of the downstream sector is that of water consumption at lithium brine facilities, which operate in some of the driest areas on the planet. Brine operations use solar, chemical, and/or physical means to produce refined lithium products for use in the battery sector. Source: Roskill.

Synhelion raises CHF 22M (US$23.6M) to support scaling of solar fuel production

Green Car Congress

The proceeds of the investment round will accelerate the company’s growth and support the scaling and commercialization of Synhelion’s solar fuels technology. Synhelion is developing two pathways to solar fuels: Redox splitting. The thermochemical splitting of CO 2 and water in a two-step redox reaction yields carbon-neutral fuels.
