Ask a Scientist: Two Dozen States Can Meet 100 Percent of Electricity Demand with Renewables by 2035

Union of Concerned Scientists

The shift from fossil fuels in the 100-percent RES scenario reduces the amount of toxic power plant air pollution much more than what we called a “no-new-policy,” or business-as-usual, scenario. Emissions of sulfur dioxide and nitrogen oxides from power plants in alliance states drop 88 percent and 77 percent respectively by 2040.

Ask a Scientist: The US Has to Do More to Meet Its Carbon Emissions Reduction Goals

Union of Concerned Scientists

IRA clean energy investments also will protect public health by cutting key toxic air pollutants, such as nitrogen oxides and sulfur dioxide, by more than 50 percent by 2050, and drastically reduce fine particulate matter, which will save hundreds of billions of dollars in 2035 alone from avoided premature deaths.

Good News—and Bad—about Fossil Fuel Power Plants in 2023 

Union of Concerned Scientists

In 2021 alone, the plants slated for retirement emitted more than 28,000 tonnes of nitrogen oxides (NO x ), 32,000 tonnes of sulfur dioxide (SO 2 ), and 51 million tonnes of carbon dioxide (CO 2 ), according to EIA data. GW of gas capacity set to retire, but also slightly outpacing the planned additions of wind power.

Unraveling LA’s Hydrogen Combustion Experiment

Legal Planet

Critically, and as we’ll discuss in greater depth shortly, hydrogen combustion (as opposed to its use in fuel cells) also leads to greater emissions of nitrogen oxides (NOx), a toxic group of pollutants regulated under the Clean Air Act. Inefficient end uses for hydrogen can further exacerbate this problem.

Bay Journal: As Federal Support Emerges, PA Wants To Be A Carbon Capture Hub

PA Environment Daily

Fossil fuel, they argue, will still be needed in the near term as a backstop for the intermittency of solar and wind power and to keep consumer power bills affordable. Read more here ] The plant would mix the captured CO2 with ammonia to produce urea, which is used in diesel exhaust systems to reduce nitrogen oxide emissions.
