thyssenkrupp greenlights construction of €2B hydrogen-powered direct reduction plant for low-CO2 steel

Green Car Congress

As part of its tkH2Steel transformation project, coal-based blast furnaces will be replaced by hydrogen-powered direct reduction plants. Thus, the Duisburg steelworks is continuing to boil steel as in the past—but with hydrogen and green power instead of coal. —Martina Merz, CEO of thyssenkrupp AG. With its capacity of 2.5

CICERO-led study finds global warming effect of leaked hydrogen almost 12x stronger than CO2

Green Car Congress

A study led by Norwegian climate center CICERO has found that the global warming effect of leaked hydrogen is almost 12 times stronger than that of CO 2. Unlike exhaust from burning coal and gas that contains CO 2 , burning hydrogen emits only water vapor and oxygen. The climate effects of hydrogen have been an under-researched topic.

Researchers Say Mix of Policies and Current or Near-Term Technologies Could Phase Out US CO2 Emissions from Coal-Fired Power Plants by 2030

Green Car Congress

CO 2 emissions from US coal-fired power plant could be phased out entirely by 2030 using existing technologies or ones that could be commercially competitive with coal within about a decade, according to a paper published online 30 April in the ACS journal Environmental Science & Technology.

billion tonnes, their highest ever level, as the world economy rebounded strongly from the COVID-19 crisis and relied heavily on coal to power that growth, according to new IEA analysis. Coal accounted for over 40% of the overall growth in global CO 2 emissions in 2021, reaching an all-time high of 15.3 billion tonnes.

Tsinghua/Argonne Study Finds That Mass Use of EVs in China Could Result in Higher CO2 and Criteria Pollutant Emissions Than Conventional and Hybrid Gasoline Vehicles Due to Coal-Fired Generation of Electricity

Green Car Congress

The researchers found that while EVs do offer a very promising solution to energy issues due to their replacement of petroleum fuels, for now “ the high pollution levels of coal-fired power plants will trade off EVs’ potential energy benefits in China ”. The power of EVs is electricity from the grid.

Roskill: CO2 emissions from lithium production set to triple by 2025

Green Car Congress

The high emissions intensity of refining concentrate to lithium carbonate or hydroxide, in part driven by China’s power grid mix and reliance of coal. The low emissions output from mining equipment and on-site vehicles, despite their comparatively high energy intensity.

EIA: CO2 emissions from US power sector have declined 28% since 2005

Green Car Congress

The power sector has become less carbon-intensive as natural gas-fired generation displaced coal-fired and petroleum-fired generation and as the noncarbon sources of electricity generation—especially renewables such as wind and solar—have grown.
