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

Green Car Congress

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. (B) MS signal and SFE values for a wireless configuration. Reece et al. Click to enlarge.

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. These structures would serve both as anchors to moor the floating turbines and as a means of storing the energy they produce. Earlier post.).

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.

ExxonMobil, MIT and Synthetic Genomics team publishes results of LCA on algal biofuels; potential for large reductions in GHG

Green Car Congress

Algae have the potential to produce large volumes of fuel per unit area of production on marginal lands using saline water unsuitable for food crops. Thus, algal biofuels could expand transportation energy supplies, without significantly displacing land and water resources that would otherwise have been used for food production.

MIT researchers develop oxygen permeable membrane that converts CO2 to CO

Green Car Congress

MIT researchers have developed a new system that could potentially be used for converting power plant emissions of carbon dioxide into carbon monoxide, and thence into useful fuels for cars, trucks, and planes, as well as into chemical feedstocks for a wide variety of products. Ghoniem’s lab is exploring some of these options.

MIT researchers devise simple catalytic system for fixation and conversion of CO2

Green Car Congress

Researchers at MIT have devised a simple, soluble metal oxide system to capture and transform CO 2 into useful organic compounds. Molybdate is relatively abundant and stable in air and water. In theory, the system could allow researchers to create a cartridge that would temporarily store carbon dioxide emitted by vehicles.

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.
