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%

Cohort of new stakeholders joins Open Hydrogen Initiative

Green Car Congress

In February 2022, GTI Energy, S&P Global Commodity Insights and the National Energy Technology Laboratory (NETL) launched the Open Hydrogen Initiative (OHI), a collaboration to further transparency into the environmental impact of hydrogen production and help unlock its full potential as an important driver of energy transitions.

Global Carbon Project: Global carbon emissions growth slows, but hits record high

Green Car Congress

Driven by rising natural gas and oil consumption, levels of CO 2 are expected to hit 37 billion metric tons this year, according to new estimates from the Global Carbon Project (GCP), an initiative led by Stanford University scientist Rob Jackson. and China account for more than half of all carbon dioxide emissions globally.

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

Green Car Congress

The ICCT has conducted a comprehensive global and temporal life-cycle assessment of GHG emissions from a variety of alternative passenger car powertrains and fuels. This study incorporates the near-term global warming potential of methane leakage emissions of natural gas and natural gas-derived hydrogen pathways.

Carnegie study finds climate impact of particulates varies greatly depending on where the pollution originated

Green Car Congress

However, while greenhouse gases cause warming by trapping heat in the atmosphere, some aerosols can have a cooling effect on the climate because the aerosol particles cause more of the sun’s light to be reflected away from the planet. Estimates indicate that aerosols have offset about a third of greenhouse gas-driven warming since the 1950s.

3 Oil Majors That Bet Big On Renewables

Green Car Congress

Despite the much-vaunted megatrend involving the global electrification drive and shift to renewable energy , the most ambitious pledges by Big Oil to pursue net-zero agendas remain weak at best. Indeed, much of Big Oil's reduction in greenhouse gas (GHG) emissions leans on the so-called natural gas bridge. 2 Total SA.

Instead, he and others are trying to invent new climate-control technology that doesn’t further exacerbate the dangers facing the planet’s climate. Winners of the 2021 Global Cooling Prize—both heat pumps—reduce cooling’s climate impact by as much as 80 percent. If, like 60 percent of the U.S. Still, in the U.S.,
