Study finds methane emissions from coal mines ~50% higher than previously thought

Green Car Congress

The amount of methane released into the atmosphere as a result of coal mining is likely approximately 50% higher than previously estimated, according to research presented at the recent annual meeting of the American Geophysical Union. The authors point out that less coal production doesn’t translate to less methane.

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. All sorts of scenarios have been developed under the assumption that carbon capture actually reduces substantial amounts of carbon.

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

Green Car Congress

This reduction is achieved through a closed-loop carbon recycling system, which could replace 90% of the coke typically used in current blast furnace-basic oxygen furnace systems and produces oxygen as a byproduct. A double perovskite, Ba 2 Ca 0.66 This reacts with the iron ore in the furnace to produce CO 2.

ArcelorMittal inaugurates €200M Steelanol carbon capture and utilization project at Ghent plant

Green Car Congress

At an event held at its steel plant in Ghent, Belgium, ArcelorMittal inaugurated its flagship carbon capture and utilization (CCU) project. It will reduce annual carbon emissions from the Ghent plant by 125,000 tonnes. This project will reduce annual carbon emissions in Ghent by 112,500 tonnes. Earlier post.)

Rhodium Group estimates US GHG fell 2.1% in 2019, driven by coal decline

Green Car Congress

This decline was due almost entirely to a drop in coal consumption. Coal-fired power generation fell by a record 18% year-on-year to its lowest level since 1975. An increase in natural gas generation offset some of the climate gains from this coal decline, but overall power sector emissions still decreased by almost 10%.

Global Carbon Budget 2022: Global fossil CO2 emissions expected to grow 1.0% in 2022

Green Car Congress

The Global Carbon Project (GCP) published its annual analysis of trends in the global carbon cycle in the journal Earth System Science Data , including an updated full-year projection for 2022. Growth in oil use, particularly aviation, and coal use are behind most of the increase in 2022. The decline in 2020 of -5.2%
