Initial research priorities will be building energy efficiency, clean coal including carbon capture and storage, and clean vehicles. 21 st Century Coal. The two Presidents pledged to promote cooperation on cleaner uses of coal, including large-scale carbon capture and storage (CCS) demonstration projects.
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).
Cutting the amount of short-lived, climate-warming emissions such as soot and methane won’t limit global warming as much as previous studies have suggested, according to a new study from the Joint Global Change Research Institute in College Park, Md., degree reduction found in earlier studies. —Smith and Mizrahi.
In addition, President Obama issued a Presidential Memorandum creating an Interagency Task Force on Carbon Capture and Storage to develop a comprehensive and coordinated federal strategy to speed the development and deployment of advanced lower-emission coal technologies.
A new international study led by McGill University (Canada) Professor Jill Baumgartner suggests that black carbon may also increase the risk of cardiovascular disease. In fact, black carbon’s effect was twice that of particulate matter, the pollutant measured most often in health studies or evaluating cleaner cookstoves.
Highly turbocharged alcohol-fueled direct-injection spark-ignition (DISI) engines operated at a high compression ratio could be as or more efficient than diesel engines while also providing advantages of lower vehicle cost, lower emissions and higher power, according to a recent modeling study by Leslie Bromberg and Daniel Cohn at MIT.
A battery produced in a jurisdiction using coal-fired electricity, for example, will have significantly higher emissions than one produced using cleaner power. Differences in battery materials and production techniques, including the location and energy mix of production, also affect the emissions profiles of different EVs.
Now, a study from University of Michigan researchers shows that when, where and how those fleet vehicles are charged can greatly impact their potential to reduce greenhouse gas emissions. The study is published in the ACS journal Environmental Science & Technology. —Maxwell Woody.
Sulfur is ubiquitous in the biosphere and often occurs in relatively high concentrations in fossil fuels, with coal and crude oil deposits commonly containing 1–2% sulfur by weight. The data came from more than 140 countries and went back as far as the 1800s, when publications even at that time tallied how much coal and copper were produced.
The Ugly Coal sucks, there's really no two ways about it. But not all use of coal is alike. The Good About half our electricity comes from coal, and that will change, at best, slowly as we move to renewables. That includes the worst, most coal dependent areas. We can make electricity many ways, some better than others.
According to an independent study by the International Institute for Applied Systems Analysis (IIASA) and the Council on Energy, Environment, and Water (CEEW), more than 674 million Indian citizens are likely to breathe air with high concentrations of PM 2.5 The study found that this share will increase to 1.4–1.7% concentrations.
A new report from the National Research Council examines and, when possible, estimates, “hidden” costs of energy production and use—such as the damage air pollution imposes on human health—that are not reflected in market prices of coal, oil, other energy sources, or the electricity and gasoline produced from them. cents per kWh.
