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.

NETL framework for assessing economic viability of recovering REEs from unconventional sources

Green Car Congress

China has been the dominant global supplier of REEs since 1988, providing up to 95% of the global REE market annually. Unconventional REE sources such as domestic coal and coal waste could yield the materials needed for the strong magnets necessary to turn wind into electricity and operate electric vehicles.

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. The open access paper by Cornell’s Robert Howarth and Stanford’s Mark Jacobson is published in the journal Energy Science and Engineering.

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

Green Car Congress

By comparison, approximately 70% of the steel produced globally is made with blast furnace technology, an extractive process fed by iron ore, coal, and limestone that emits about two tons of carbon dioxide for every ton of steel produced. Existing electric arc furnaces account for 70% of steel production in the US.

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. Source: The ICCT.

Keliber says studies show its lithium hydroxide will have smaller carbon footprint than most of the competition

Green Car Congress

Consulting company Wood Mackenzie analyzed seven existing or planned global lithium chemicals production chains, ending in Rotterdam in Holland. In the comparison, Keliber shows the lowest emission intensity of 4.38 The CO 2 emissions are more than 16 tonnes/produced tonne, due to the dominance of coal as the energy source.?.
