A new assessment of the viability of coal-to-liquids (CTL) technology by researchers from the MIT Joint Program on the Science and Policy of Global Change (JPSPGC) found that without climate policy, CTL has the potential to account for around a third of global liquid fuels by 2050.

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).

is showcasing a GaN-based, dc-to-dc boost converter running at more than 99% efficiency. Energy loss that occurs during power conversion is equivalent to the daily output of 318 coal plants, and costs the US economy $40 billion per year. Perreault, MIT). At APEC, startup Transphorm Inc.

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.

ARPA-E Selects 37 Projects for $106M in Funding in Second Round; Electrofuels, Better Batteries and Carbon Capture

Green Car Congress

Today’s technologies for making biofuels all rely on photosynthesis—either indirectly by converting plants to fuels or directly by harnessing photosynthetic organisms such as algae. This process is less than 1% efficient at converting sunlight to stored chemical energy. Electrofuels: Biofuels from Electricity. Engineering E.

The Complex Calculus of Clean Energy and Zero Emissions

Cars That Think

So when I went to MIT to do my Ph.D., The second reason is that the grid we have is built out to places where there were coal mines and hydropower dams, not where there’s the best wind and sun. Solar panels convert solar radiation to power linearly, in proportion to the amount of sunlight.
