New Fraunhofer membrane technology enables co-transport of hydrogen and natural gas

Green Car Congress

Researchers at the Fraunhofer-Gesellschaft have developed a membrane technology for the energy-efficient and economic separation of hydrogen from natural gas. This technology makes it possible for the two substances to be routed through the national natural gas grid together and then isolated from one another at their final destination.

ICCT life-cycle analysis finds no climate benefit in using LNG as marine fuel

Green Car Congress

The results of a new analysis by the International Council on Clean Transportation (ICCT) show that, when combined with a trend toward higher methane leakage and combustion slip, there is no climate benefit from using liquefied natural gas (LNG) as a marine fuel—regardless of the engine technology.

Study: annual climate impact of wild pigs could be greater than 1.1M cars

Green Car Congress

The researchers used predictive population models coupled with advanced mapping techniques to estimate the climate damage wild pigs are causing across five continents. Since soil contains nearly three times as much carbon than in the atmosphere, even a small fraction of carbon emitted from soil has the potential to accelerate climate change.

Green NCAP LCA study shows detrimental climate and energy impact of increasing vehicle weight, including EVs

Green Car Congress

The results of the Life Cycle Assessment (LCA) of greenhouse gas emissions and primary energy demand of the cars tested by Green NCAP in 2022 show that the current and continuous trend towards larger and heavier cars, significantly increases the negative impact on climate and energy demand. MWh of extra energy used.

SoCalGas to test technology that separates hydrogen from natural gas when the two are blended in pipelines

Green Car Congress

With clean hydrogen gaining recognition worldwide as a carbon-free fuel capable of making a significant contribution to addressing climate change, Southern California Gas Co. SoCalGas) will field test a new technology that can simultaneously separate and compress hydrogen from a blend of hydrogen and natural gas.

Study finds total greenhouse gas footprint of blue hydrogen “quite high” due to fugitive methane

Green Car Congress

“Blue” hydrogen—produced through steam methane reforming (SMR) of natural gas or coal gasification, but with CO 2 capture and storage—is being described as having low or zero carbon emissions. Even if true though, the use of blue hydrogen appears difficult to justify on climate grounds. For our default assumptions (3.5%
