Even if you have 100 percent capture from the capture equipment, it is still worse, from a social cost perspective, than replacing a coal or gas plant with a wind farm because carbon capture never reduces air pollution and always has a capture equipment cost. Only when wind replaced coal itself did social costs decrease.
Energy company RWE and steel producer ArcelorMittal have signed a memorandum of understanding to work together to develop, build and operate offshore wind farms and hydrogen facilities that will supply the renewable energy and green hydrogen required to produce low-emissions steel in Germany.
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).
Researchers at MIT are proposing using a variation on pumped hydroelectric systems for storage of electricity produced by offshore wind farms.

Electric vehicles charged in coal-heavy regions can create more human health and environmental damages from life cycle air emissions than gasoline vehicles, according to a new consequential life cycle analysis by researchers from Carnegie Mellon University.
My favorite part of this next CicLaVia is t he Bike Parade coming from my friends at Greenpeace and Sierra Club which they’re calling ROLL AGAINST COAL. In case you didn’t know, the City of Los Angeles still gets 40% of its electricity from coal-fired power plants, the dirtiest polluters and greenhouse gassers on the planet.
While more effort is needed to reach that goal, one energy organization has predicted that renewables will overtake coal generation as the world’s largest electricity source in early 2025. There are still some big hurdles to overcome, including the difficult global macroeconomic environment.” “For In the U.S.,
The least expensive way for the Western US to reduce greenhouse gas emissions enough to help prevent the worst consequences of global warming is to replace coal with renewable and other sources of energy that may include nuclear power, according to a new study by University of California, Berkeley, researchers. —Daniel Kammen.
In a paper published in the journal Atmospheric Environment , they report on the findings from a suite of scenarios designed to quantify the effect of both the magnitude of EV market penetration and the source of electricity generation used to power them. coal, oil, natural gas, and biomass). Winter while PM 2.5 2019.04.003.
They also note that large-scale production of synthetic fuels or hydrogen from coal or gas offers the potential for GHG emissions reduction—but only if CO 2 can be captured and stored. Producing synthetic gas (SNG) from wind electricity (e.g., High quality diesel fuel can be produced from natural gas (GTL) and coal (CTL).
As the percentage of electricity supply from wind and solar increases, grid operators will need to employ strategies and technologies, including energy storage, to balance supply with demand given the intermittency of the renewable supply. Coal- and natural gas-fired power plants are responsible for at least a third of those emissions.
A large part of this potential comes from six relatively standardized categories: solar and wind energy; efficient appliances; efficient passenger cars; afforestation and stopping deforestation. There are an estimated 6,683 operating coal-fired power plants in the world, with a combined capacity of 1,964 GW.
Whatever the future energy mix, it''s becoming apparent that coal and gas are both hugely consumptive and not entirely great for the environment--even if they provide large swathes of the world with their energy.
If the US military increases its use of alternative jet and naval fuels that can be produced from coal or various renewable resources, including seed oils, waste oils and algae, there will be no direct benefit to the nation’s armed forces, according to a new RAND Corporation study. —Alternative Fuels for Military Applications.
