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. For our default assumptions (3.5% Even if true though, the use of blue hydrogen appears difficult to justify on climate grounds.

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.

Electra raises $85M to advance Low-Temperature Iron process; electrochemical refining at 60?C

Green Car Congress

By comparison, 69% of steel today is made at approximately 1,600 degrees Celsius (2,912 degrees Fahrenheit) using coal, emitting about two tons of carbon dioxide for every ton of steel produced. gigatons of direct and indirect carbon dioxide emissions annually, or 10% of the global total.

Nucor investing in start-up company Electra developing zero-carbon iron technology

Green Car Congress

This material will be used in the steelmaking process to offset other high-quality metallics that come with higher greenhouse gas emissions. Electra uses renewable energy to refine low-grade iron ores into high-purity iron through electrochemical and hydrometallurgical processes. Electra’s process results in zero carbon dioxide emissions.

Rice study finds using natural gas for electricity and heating, not transportation, more effective in reducing GHGs

Green Car Congress

Rice University researchers have determined a more effective way to use natural gas to reduce climate-warming emissions would be in the replacement of existing coal-fired power plants and fuel-oil furnaces rather than burning it in cars and buses.
