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. The 1,000 wind turbines that the spheres could anchor could, on average, replace a conventional on-shore coal or nuclear plant. MIT has filed for a patent on the system. Earlier post.).

MIT Report Finds Natural Gas Has Significant Potential to Displace Coal, Reducing Greenhouse Gas Emissions; Role in Transportation More Limited

Green Car Congress

Natural gas will play a leading role in reducing greenhouse-gas emissions over the next several decades, largely by replacing older, inefficient coal plants with highly efficient combined-cycle gas generation, according to a major new interim report out from MIT. The first two reports dealt with nuclear power (2003) and coal (2007).

MIT researchers build model simulating atmospheric transport of PAHs; how chemicals get to the Arctic

Green Car Congress

MIT researchers have built a model to simulate long-range atmospheric transport of polycyclic aromatic hydrocarbons (PAHs). Friedman’s work will provide a foundation for ongoing work in Selin’s research group at MIT, in collaboration with the University of Rhode Island and the Harvard School of Public Health.

MIT researchers conclude fundamental changes in the US energy-innovation system are needed to meet challenges of climate change and energy supply

Green Car Congress

A three-year study by a team of researchers based at MIT has concluded that fundamental changes are needed in the US energy-innovation system. The study was carried out at the MIT Industrial Performance Center and involved faculty and students from nine MIT departments. Business as usual is unsustainable over the long run.

MIT and U. Texas report urges combining and scaling up carbon capture and storage with enhanced oil recovery

Green Car Congress

A report from MIT and The University of Texas at Austin urges the US to accelerate efforts to pursue carbon capture and storage (CCS) in combination with enhanced oil recovery (EOR), a practice that could increase domestic oil production while significantly curbing emissions of carbon dioxide. Schematic of a CO 2. EOR System.

MIT researchers propose massive bloom of methanogenic microbes may have triggered end-Permian extinction

Green Car Congress

However, such arguments have been difficult to justify quantitatively, the MIT team notes; quantitative estimates of direct volcanic outgassing are much too small to account for the changes in the carbon cycle. Other proposals suggest secondary effects of the volcanism—such as raging coal fires—as the mechanism.
