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).

New process produces high-octane synthetic fuel from low-octane Fischer-Tropsch gasoline

Green Car Congress

A team in Russia has developed a novel and simple strategy to produce high-octane synthetic fuel based on low-octane gasoline Fischer-Tropsch product via new two-stage processes in Fischer-Tropsch synthesis involving isomerization of alkenes and a methoxylation process. A paper on their work is published in the journal Fuel.

SGH2 building largest green hydrogen production facility in California; gasification of waste into H2

Green Car Congress

SGH2’s gasification process uses a plasma-enhanced thermal catalytic conversion process optimized with oxygen-enriched gas. Producers of so-called blue, gray and brown hydrogen use either fossil fuels (natural gas or coal) or low-temperature gasification (.

The Case for Nuclear Cargo Ships

Cars That Think

“At the same time, it’s becoming apparent that alternative-fuel solutions we’re looking at have big drawbacks, and that producing these fuels will take a lot of green power that will be needed to replace coal and gas on shore. Russia currently operates seven nuclear-powered icebreakers. We needed to get the conversation started.”

Global CO2 emissions up 3% in 2011; per capita CO2 emissions in China reach EU levels

Green Car Congress

Some of the findings of the report include: Global consumption of coal (responsible for about 40% total CO 2 emissions) grew in 2011 by 5%, whereas global consumption of natural gas and oil products increased by only 2% and 1%, respectively. Coal consumption in China increased by 9.7%

Noting that coal accounts for roughly 25% of the world energy supply and 40% of the carbon emissions. Chu said that it was highly unlikely that the US, Russia, China and India, which account for two-thirds of the coal reserves, “ will turn their back on coal anytime soon.”.for At geological storage densities of CO 2 (0.6

Separate MIT, IEA reports both outline major expansion in role of natural gas; caution on climate benefits

Green Car Congress

In the US, a combination of demand reduction and displacement of coal-fired power by gas-fired generation is the lowest cost way to reduce CO 2 emissions by up to 50%. At least for the near term, that would entail facilitating energy demand reduction and displacement of some coal generation with natural gas.
