MIT researchers develop optimized sulfidation separation process for rare earth and other key metals

Green Car Congress

New processing methods developed by MIT researchers could help ease looming shortages of the essential metals that power everything from phones to automotive batteries by making it easier to separate these rare metals from mining ores and recycled materials. —Antoine Allanore.

Scientists figured out a way to clean dust off of solar panels without using water

Electrek

Dust on solar panels reduces their output significantly, so they need to be kept clean. Scientists at the Massachusetts Institute of Technology (MIT) say they have a solution. The post Scientists figured out a way to clean dust off of solar panels without using water appeared first on Electrek.

A New Energy-Efficient Hydrogel Pulls Water From Air

Cars That Think

Using a new kind of hydrogel material, researchers at the University of Texas at Austin have pulled water out of thin air at temperatures low enough to be achieved with sunlight. Atmospheric water harvesting draws water from humidity in the air. The material is a hydrogel, a polymer network that naturally retains a lot of water.

Researchers from MIT and Sun Catalytix develop an artificial leaf for solar water splitting to produce hydrogen and oxygen

Green Car Congress

The traces are for solar cells of 7.7% Researchers led by MIT professor Daniel Nocera have produced an “artificial leaf”—a solar water-splitting cell producing hydrogen and oxygen that operates in near-neutral pH conditions, both with and without connecting wires. solar-to-fuels systems.

MIT Researchers Identify New Low-Cost Water-Splitting Catalyst

Green Car Congress

Daniel Nocera and his associates have found another formulation, based on inexpensive and widely available materials, that can efficiently catalyze the splitting of water molecules using electricity. Earlier post.). Earlier post.). Materials for the new catalyst are even more abundant and inexpensive than those required for the first.

MIT researchers propose subsea version of pumped hydro for renewable energy storage

Green Car Congress

Researchers at MIT are proposing using a variation on pumped hydroelectric systems for storage of electricity produced by offshore wind farms. Geologic pumped hydroelectric storage works by pumping water to a reservoir behind a dam when electricity demand is low. Earlier post.).
