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.

Researchers from MIT and Sun Catalytix develop an artificial leaf for solar water splitting to produce hydrogen and oxygen

Green Car Congress

Researchers led by MIT professor Daniel Nocera have produced an “artificial leaf”—a solar water-splitting cell producing hydrogen and oxygen that operates in near-neutral pH conditions, both with and without connecting wires. The cells were operated in a two-electrode cell configuration. (B) Reece et al. Click to enlarge.

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. Their analysis is published in the Journal of Economic Perspectives.

ARPA-E selects 33 projects for $66M in awards; advanced biocatalysts for gas-to-liquids and lightweight metals

Green Car Congress

While chemically converting natural gas to liquid fuels (GTL) is a proven technology that increases volumetric energy density, the current conversion approach through Fischer-Tropsch (FT-GTL) is challenged by both high capital costs and low conversion efficiencies. Enzyme Engineering for Direct Methane Conversion.

GMZ-led project tracking to deliver vehicular thermoelectric generators for Bradley Fighting Vehicle, Honda Accord

Green Car Congress

GMZ Energy, a provider of advanced nano-structured thermoelectric generation technology, was co-founded by MITs Professor Gang Chen and collaborator Zhifeng Ren of the University of Houston. Thermoelectric materials convert temperature differences into electric voltage; a TEG in a vehicle is designed to convert waste heat to power.

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. Nailing down the costs of hydrogen-fired electricity generation, however, was challenging. —Drake Hernandez. Much of this information was publicly available.
