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.).

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. The cells were operated in a two-electrode cell configuration. (B) Reece et al. Click to enlarge.

MIT team synthesizes all carbon nanofiber electrodes for high-energy rechargeable Li-air batteries

Green Car Congress

A team at MIT, led by Carl V. The carbon nanofiber electrodes are substantially more porous than other carbon electrodes, and can therefore more efficiently store the solid oxidized lithium (Li 2 O 2 ) that fills the pores as the battery discharges.

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

Green Car Congress

At the 2011 Algae Biomass Summit in Minneapolis, Dr. Michael Matturro, Corporate Programs Laboratory Director for ExxonMobil, provided a brief overview of the scope of the work. In the accumulation cases, oil accumulated and stored in the algal cells is extracted from biomass that is harvested from the growth ponds. Craig Venter.

National University of Singapore researchers devise membrane-based supercapacitors; possible new route to high-performance supercapacitive energy storage

Green Car Congress

When sandwiched between and charged by two metal plates, the membrane can store charge at 0.2 With existing technologies based on liquid electrolytes, it costs about US$7 to store each farad. With the advanced energy storage membrane, the cost to store each farad falls to US$0.62. —Xie et al. —Xian Ning Xie.
