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. solar generation exceeding electrolyzer capacity). Process flow diagram and construction phase boundary. Palmer et al.

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.,

Researchers use quantum computing method to optimize molecular photoswitches for solar energy harvesting

Green Car Congress

Molecular photoswitches that can both convert and store energy could be used to make solar energy harvesting more efficient. The procedure was based on a dataset of more than 400,000 molecules, which the researchers screened to find the optimum molecular structure for solar energy storage materials. 202309543

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.
