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%.

Hydrogen embrittlement in ferritic steels creates complications for clean energy storage, transportation

Green Car Congress

As the global energy market shifts from coal, petroleum fuel, and natural gas to more environmentally friendly primary energy sources, hydrogen is becoming a crucial pillar in the clean energy movement. The researchers highlighted several combinations of techniques and methods, including atom probe tomography (APT).

Study suggests China urban passenger transport emissions could peak in 2030

Green Car Congress

A team of researchers in China suggest that, in the context of promoting the use of clean fuel vehicles and increasing vehicle fuel efficiency, CO 2 emissions of China’s urban passenger transport sector could reach a peak of 225 MtCO 2 in 2030. A paper on their study appears in the journal Energy Policy.

EPA GHG Inventory shows US GHG down 1.7% y-o-y in 2019, down 13% from 2005

Green Car Congress

This decrease was driven largely by a decrease in emissions from fossil fuel combustion resulting from a decrease in total energy use in 2019 compared to 2018 and a continued shift from coal to natural gas and renewables in the electric power sector. Transportation. CO 2 emissions decreased 2.2% from 2018 to 2019. Source: EPA.

EPA: US GHG fell 0.5% y-o-y in 2017; power sector down by 4.2%, transportation up 1.21%

Green Car Congress

This decrease was largely driven by a decrease in emissions from fossil fuel combustion, which was a result of multiple factors including a continued shift from coal to natural gas and increased use of renewables in the electric power sector, and milder weather that contributed to less overall electricity use.

Study from Thuringia shows 50% of harmful soot comes from local sources, 50% from long-distance transport

Green Car Congress

During transport, ageing processes not only change the chemical composition of the particles, but also influence their physical properties (e.g. Long-distance transport also affects the chemical composition of aerosol particles through the origin of the air masses. forest fires).
