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. 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 and IEA reports take different views of the future of natural gas in transportation

Green Car Congress

MIT and the IEA both have newly released reports exploring the potential for and impact of a major expansion in global usage of natural gas, given the current re-evaluation of global supplies. MIT: leaning toward conversion for light-duty vehicles. Earlier post.) I.e., on an energy basis at the point of use, the CO 2.

U Chicago, MIT study suggests ongoing use of fossil fuels absent new carbon taxes

Green Car Congress

A paper by a team from the University of Chicago and MIT suggests that technology-driven cost reductions in fossil fuels will lead to the continued use of fossil fuels—oil, gas, and coal—unless governments pass new taxes on carbon emissions. for oil, 24% for coal, and 20% for natural gas.

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/RAND Study Concludes Three Types of Alternative Jet Fuel May Be Available in Commercial Quantities Over the Next Decade

Green Car Congress

The five different fuel groups were those derived: from conventional petroleum; from unconventional petroleum; synthetically from natural gas, coal, or combinations of coal and biomass via the FT process; renewable oils; and alcohols. Click to enlarge.
