A new study by Michael Wang and Jeongwoo Han at Argonne National Laboratory and Xiaomin Xie at Shanghai Jiao Tong University assesses the effects of carbon capture and storage (CCS) technology and cellulosic biomass and coal co-feeding in Fischer-Tropsch (FT) plants on energy use and greenhouse gas (GHG) emissions of FT diesel (FTD).
One of the common arguments you hear from people in America who are not fans of the idea of electric vehicles is that they are mostly charged from electricity produced from coal power plants. Heavy Coal Using States Accounted for Only 10% of EV Sales in 2020. The argument that EVs are powered mostly from coal simply isn’t true.
An analysis of near-term spending plans on renewables by the biggest oil and gas companies shows that real investments in renewable energy will continue to pale in comparison to capex plans for greenfield fossil fuel projects. Indeed, much of Big Oil's reduction in greenhouse gas (GHG) emissions leans on the so-called natural gas bridge.
Furthermore, coproduction systems that utilize a co-feed of biomass and coal (CBTL) and incorporate CO 2 capture and storage (CCS) in the design offer attractive opportunities for decarbonizing both liquid fuels and power generation simultaneously.

The US electric power sector burned through a record amount of natural gas in recent weeks, a sign of the shifting power generation mix and also a signal that natural gas supplies could get tighter than many analysts had previously expected. Natural gas consumption patterns are much more seasonal than for oil.
This is not unexpected ”, said Gunnar Myhre, senior research fellow at CICERO and one of the scientists behind the article. While emissions from oil and gas have decreased, emissions from coal have remained stable; the share of coal as a fuel has increased.
In gasification, slag is made from mineral impurities that remain after a carbon feedstock such as coal has been gasified. Hydrogen gas, which is useful in chemical manufacturing and industrial applications including fuel cells, can be economically made from water using the same method. 2014.01.104.
They used a lot more coal than they originally admitted to, several hundred million tons more. Like many other people, we were writing articles around 2000 about the decline in China’s energy consumption in the late 1990s. Like the United States, China has become among the world’s largest importers of oil, gas and coal.
FT synthesis uses syngas (primarily H 2 and CO) generated from coal, natural gas, or biomass. For biomass, synthesis gas production occurs via oxygen/steam gasification or partial oxidation reactions. The resulting synthesis gas is then cleaned and adjusted to synthesis requirements. Unruh et al. Unruh et al. Unruh et al.
Used as an alternative diesel fuel, dimethyl ether, which is produced by the conversion of syngas derived from coal, biomass, or natural gas, offers lower NO x emissions and near-zero smoke evolution compared to conventional petroleum diesel fuel in addition to being a non-petroleum-sourced fuel. by the water-gas shift (WGS) reaction.
Natural gas or coal is used as the energy source of the ammonia industry. Scientific Reports 3, Article number: 1145 doi: 10.1038/srep01145. tons of CO 2 is released per ton of ammonia produced. Globally 245 million tons of CO 2 were released by the ammonia industry in 2010 equivalent to about 50% of the UK CO 2 emissions (495.8
Primary energy sources in model include fossil fuels (crude oil, natural gas, and coal); non-renewable non-fossil sources (nuclear); and renewable sources (hydroelectric, wind, solar, and biomass).
