Study findings suggest that switching from coal to natural gas would do little for global climate

Green Car Congress

The study will appear next month in the peer-reviewed journal Climatic Change Letters. The study will appear next month in the peer-reviewed journal Climatic Change Letters. Relying more on natural gas would reduce emissions of carbon dioxide, but it would do little to help solve the climate problem. —Tom Wigley.

Novel adaptation for existing blast furnaces could reduce steelmaking emissions by 88%; closed-loop carbon recycling

Green Car Congress

Researchers from the University of Birmingham have designed a novel adaptation for existing blast furnaces that could reduce CO 2 emissions from the steelmaking industry by nearly 90%. The perovskite can be regenerated to its original form in a chemical reaction that takes place in a low oxygen environment.

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

Green Car Congress

The release of this enormous investment comes in the midst of the company’s transformation, in what is also for all concerned an extremely challenging environment. As part of its tkH2Steel transformation project, coal-based blast furnaces will be replaced by hydrogen-powered direct reduction plants. Capacity will be 2.5

Stanford study finds current carbon capture technology inefficient & increases air pollution

Green Car Congress

Jacobson, professor of civil and environmental engineering at Stanford University, suggests that carbon capture technologies are inefficient and increase air pollution. Upstream emissions are emissions, including from leaks and combustion, from mining and transporting a fuel such as coal or natural gas.). A study by Mark Z.

HEI study links fossil fuel combustion with more than 1 million deaths globally

Green Car Congress

Coal combustion alone was responsible for half of those deaths, with natural gas and oil combustion accounting for the other half. in outdoor air comes from anthropogenic fuel combustion, suggesting that integrating air quality, energy, and climate policies is likely to bring substantial health benefits.

Tsinghua University provincial-level lifecycle study finds fuel-cycle criteria pollutants of EVs in China could be up to 5x those of natural gas vehicles due to China’s coal-dominant power mix

Green Car Congress

In regions where the share of coal-based electricity is relatively low, EVs can achieve substantial GHG reduction, the team reports in a paper in the ACS journal Environmental Science & Technology. According to the 12 th Five-Year Plan of the China Coal Industry (2011?2015)

Study concludes abundant shale gas is neither climate hero nor villain; need for targeted GHG reduction policy

Green Car Congress

While natural gas can reduce greenhouse emissions when it is substituted for higher-emission energy sources, abundant shale gas is not likely to substantially alter total emissions without policies targeted at greenhouse gas reduction, according to a new study by two researchers at Duke University. —Newell and Raimi.
