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. 202300951

Stanford researchers make ammonia from air and water microdroplets

Green Car Congress

Stanford researchers, with a colleague from King Fahd University of Petroleum and Minerals, have developed a simple and environmentally sound way to make ammonia with tiny droplets of water and nitrogen from the air. The conversion rate reaches 32.9 ± 1.38 Water microdroplets are the hydrogen source for N 2 in contact with Fe 3 O 4.

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.

IISA study proposes using airships for efficient cargo or hydrogen transportation

Green Car Congress

Reintroducing airships into the world’s transportation mix could contribute to lowering the transport sector’s carbon emissions and can play a role in establishing a sustainable hydrogen based economy, according to a new IIASA-led study. The open-access paper is published in the journal Energy Conversion and Management: X.

Researchers use multifunctional co-solvent pair to uncover molecular principles of biomass breakdown for conversion to transportation fuels

Green Car Congress

Plant cell walls resist chemical or biological degradation, making the breakdown of lignocellulosic biomass into renewable chemical precursors for conversion into chemicals and transportation fuels challenging and costly. Co-solvents THF and water cause lignin to dissociate from itself and cellulose, expanding into a random coil.

SOLAR-JET project demonstrates solar-driven thermochemical conversion of CO2 and water to jet fuel

Green Car Congress

The EU-funded SOLAR-JET project has demonstrated the production of aviation kerosene from concentrated sunlight, CO 2 captured from air, and water. The process has also the potential to produce any other type of fuel for transport applications, such as diesel, gasoline or pure hydrogen in a more sustainable way.
