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 boost efficiency of carbon capture and conversion systems

Green Car Congress

Researchers at MIT have developed a method that could significantly boost the performance of carbon capture and conversion systems that use catalytic surfaces to enhance the rates of carbon-sequestering electrochemical reactions. The movement through water is sluggish, which slows the rate of conversion of the carbon dioxide.

MIT researchers use genetically modified virus to template nanotubes that improve solar-cell efficiency by nearly one-third

Green Car Congress

Researchers at MIT led by Drs. Using the nanocomposites as photoanodes in dye-sensitized solar cells, they achieved a power conversion efficiency in the solar cells of 10.6%, up from 8%—an increase of almost one-third. This new method used to enhance solar cell performance is quite different, Belcher says.

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 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.

MIT team outlines path to low-cost solar-to-fuels devices; the artificial leaf

Green Car Congress

A team of researchers at MIT has described a framework for efficiently coupling the power output of a series-connected string of single-band-gap solar cells to an electrochemical process that produces storable fuels.

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.).
