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. —MITEI Director Ernest J.

MITEI study finds hydrogen-generated electricity is a cost-competitive candidate for backing up wind and solar

Green Car Congress

A team at MITEI (MIT Energy Initiative) has found that hydrogen-generated electricity can be a cost-competitive option for backing up wind and solar. Currently, plants burning fossil fuels, primarily natural gas, fill in the gaps as peaker plants—a tendency that is likely to grow pari passu with VREs.

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.

Cars That Think

The same is true in reverse, when solar panels lose some of the energy in photons as heat instead of it all being converted into electrons. A thermophotovoltaic (TPV) cell developed by engineers at MIT has eclipsed the 40-percent-efficiency mark. But the tide looks to be turning. Felice Frankel One Large Rat, Hold the Droppings.

MIT researchers boost efficiency of carbon capture and conversion systems

Green Car Congress

Researchers at MIT have developed a method that could significantly boost the performance of carbon capture and conversion systems that use catalytic surfaces to enhance the rates of carbon-sequestering electrochemical reactions. This output can help to subsidize the process, offsetting the costs of reducing greenhouse gas emissions.

Innovative hybrid rotor compressor design can extend productive life of stripper wells; improved transport and efficiency, lowered operating costs

Green Car Congress

OsComp Systems, a startup formed by MIT alumni, has developed , with support from the US Department of Energy (DOE), a hybrid rotary compressor design that decreases the energy required to compress and transport natural gas, lowers operating costs, improves efficiencies and reduces the environmental footprint of well site operations.

DOE awards $7M to eight oxy-combustion coal technology projects; carbon capture, utilization and storage

Green Car Congress

The oxy-combustion process replaces the air used for combustion with a mixture of oxygen and recycled plant emissions (flue gas) and/or water for temperature control. The new selections announced today are part of a two-phase effort to evaluate and develop advanced oxy-combustion projects that yield cost-competitive options for CCUS.
