Researchers split water by altering photosynthetic machinery in plants; semi-artificial photosynthesis

Green Car Congress

A new study, led by academics at St John’s College, University of Cambridge, has used semi-artificial photosynthesis to explore new ways to produce and store solar energy. They used natural sunlight to convert water into hydrogen and oxygen using a mixture of biological components and manmade technologies. Katarzyna P.

DOE announces finalists of Geothermal Lithium Extraction Prize

Green Car Congress

The United States depends on other countries for nearly all its lithium supply and mining the mineral strains water resources and can harm the environment. Using brines already produced by geothermal energy presents a solution because it is an environmentally friendly process that yields lithium.

Study finds GWP of electrolyzed hydrogen to meet ORD’s fuel needs would be 2.5x that of fossil fuels with 2020 grid mix

Green Car Congress

Phil Ansell, an aerospace engineer at the University of Illinois Urbana-Champaign, modeled the life cycle carbon dioxide equivalent emissions of liquid hydrogen production required to meet the fuel needs of Chicago’s O’Hare International Airport (ORD) with today’s electric grid mix. Ansell presented his findings at AIAA Aviation 2023 in June.

Audi Environmental Foundation, TUB developing microplastics filter for tire wear particles

Green Car Congress

The Audi Environmental Foundation is developing filters for urban runoff in conjunction with the Technical University of Berlin (TUB). The filters prevent tire wear particles and other environmentally harmful substances from being washed into sewers and bodies of water along with rainwater.

Detailed snapshots of photosynthesis at room temperature using SLAC’s X-ray laser show water-splitting reaction

Green Car Congress

One of its molecular mysteries of photosynthesis involves how the photosystem II protein complex harvests energy from sunlight and uses it to split water into hydrogen and oxygen. Zeroing in on water-splitting. Previously, the resting state of photosystem II had been seen in detail using samples that were frozen.
