New protocol for creating single atom iridium catalysts boosts water-splitting performance

Green Car Congress

A new way of anchoring individual iridium atoms to the surface of a catalyst significantly increased its efficiency in splitting water molecules, scientists from the Department of Energy’s SLAC National Accelerator Laboratory and Stanford University reported in an open-access paper in Proceedings of the National Academy of Sciences (PNAS). …we

Xcel Energy, INL to use nuclear energy for clean hydrogen production; HTSE

Green Car Congress

Minneapolis-based Xcel Energy will work with Idaho National Laboratory to demonstrate a system that uses a nuclear plant’s steam and electricity to split water. The new project is the first to pair a commercial electricity generator with high-temperature steam electrolysis (HTSE) technology. Earlier post.) Prairie Island.

Geologists discover new path to rare earth mineral formation; implications for green energy and tech industries

Green Car Congress

Vegetation appears red, grassland is light brown, rocks are black, and water surfaces are green. There are more than 250 known REE-bearing minerals, but only three are economically viable and exploited commercially. Two circular open-pit mines are visible, as well as a number of tailings ponds and tailings piles. Image: NASA.

Heat Pumps Take on Cold Climates

Cars That Think

The challenge will conclude later this year, and prototypes will likely be ready for commercialization in 2025. Katie Davis, Trane Technologies The colder the temperature outside, the harder heat pumps must work to extract and move enough heat to maintain the home’s temperature. Heat pumps work by moving and compressing fluids.
