ICCT LCA study finds only battery and hydrogen fuel-cell EVs have potential to be very low-GHG passenger vehicle pathways

Green Car Congress

This study incorporates the near-term global warming potential of methane leakage emissions of natural gas and natural gas-derived hydrogen pathways. Natural gas does not offer climate benefits compared to gasoline and diesel, and many biofuel pathways do not, either.

FEV testing finds Transient Plasma ignition system increases fuel efficiency and decreases emissions

Green Car Congress

Data was collected with the stock ignition system with a representative ignition strategy, followed by comparison to a drop-in replacement with the TPS nanosecond pulsed power ignition system (coil and plug). The Toyota 2.5L engine was tested at FEV North America and results indicate improvements over the stock ignition system.

Synbio company Intrexon and Dominion partner to commercialize bioconversion of natural gas to isobutanol in Marcellus and Utica Basins

Green Car Congress

Intrexon’s proprietary methanotroph bioconversion platform uses optimized microbial cell lines to convert natural gas into higher carbon compounds such as isobutanol and farnesene under ambient temperatures and pressures. Methanotrophic bacteria oxidize methane as their sole carbon source to support cellular metabolism and growth.

Wärtsilä in coalition to promote LNG as a marine fuel

Green Car Congress

Wärtsilä and other leading marine industry players have formed a coalition, known as SEA/LNG, to accelerate the widespread adoption of liquefied natural gas (LNG) as a marine fuel. LNG offers significant environmental advantages for shipping compared to heavy fuel oil (HFO), which remains the predominant fuel used today.

Harvard team finds large-scale US wind power would cause warming that would take roughly a century to offset

Green Car Congress

All large-scale energy systems have environmental impacts, and the ability to compare the impacts of renewable energy sources is an important step in planning a future without coal or gas power. Their analysis focused on the comparison of climate impacts and benefits. degrees Celsius. —David Keith.

Heat Pumps—The Well-Tempered Future of A/Cs

Cars That Think

And anything, like electrically powered heat pumps, that can shift heating away from natural gas furnaces to cleaner sources of energy would also have a big climate impact, because 63 percent of American homes get their heat from natural gas. What are the pros and cons of a heat pump? In the U.S.,
