Comparative genome study finds ancestral fungus may have influenced end of coal formation; potential resource for biofuel production

Green Car Congress

Coal deposits—the fossilized remains of plants—were formed during a 60-million year period from around 360 to 300 million years ago. Instead of accumulating as peat, which eventually was transformed into coal, the great bulk of plant biomass decayed and was released into the atmosphere as carbon dioxide.

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

Green Car Congress

We present here a first-principles study of the sector coupling between a thermochemical carbon dioxide (CO 2 ) splitting cycle and existing blast furnace – basic oxygen furnace (BF-BOF) steel making for cost-effective decarbonisation. If implemented in the UK alone, the system could deliver cost savings of £1.28 2023.135963.

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)

Harvard team finds large-scale US wind power would cause warming that would take roughly a century to offset

Green Car Congress

All large-scale energy systems have environmental impacts, and the ability to compare the impacts of renewable energy sources is an important step in planning a future without coal or gas power. Wind beats coal by any environmental measure, but that doesn’t mean that its impacts are negligible. Source: Miller and Keith (2018a).

Chalmers team develops method to reduce levels of mercury in sulfuric acid

Green Car Congress

In the latter case, mercury, which is naturally present in the ore, can end up in the finished products. According to a report from the United Nations Environment Programme (UNEP), emissions of mercury to the atmosphere increased by an estimated 20% from 2010 to 2015. Recycled streams in the smelters can also contain mercury.

MIT Report Finds Natural Gas Has Significant Potential to Displace Coal, Reducing Greenhouse Gas Emissions; Role in Transportation More Limited

Green Car Congress

Natural gas will play a leading role in reducing greenhouse-gas emissions over the next several decades, largely by replacing older, inefficient coal plants with highly efficient combined-cycle gas generation, according to a major new interim report out from MIT. The first two reports dealt with nuclear power (2003) and coal (2007).

Hyperbaric Centrifuge Technology Successfully Dewaters Coal Fines

Green Car Congress

A dewatering technology developed at Virginia Tech has succeeded in reducing the moisture content of ultrafine coal to less than 20%, transforming it to a salable product. During recent prototype tests at Arch Coal Company’s Cardinal plant in Logan County, W.Va., Roe-Hoan Yoon. as part of a license agreement with Virginia Tech.
