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.

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.

MIT team engineers yeast to be more tolerant to toxic byproducts, boosting biofuels production; “tolerance module”

Green Car Congress

To try to expand biofuels’ potential impact, a team of MIT engineers has now found a way to expand the use of a wider range of nonfood feedstocks to produce such fuels. The MIT researchers developed a way to circumvent that toxicity, making it feasible to use those sources, which are much more plentiful, to produce biofuels.

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.).

MIT researchers advancing development of supercritical water upgrading of heavy crude; lower cost, energy use and CO2

Green Car Congress

Findings by MIT researchers could help advance the commercialization of supercritical water technology for the desulfurization and upgrading of high-sulfur crude oil into high-value, cleaner fuels such as gasoline without using hydrogen—a major change in refining technology that would reduce costs, energy use, and CO 2 emissions.

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.
