In 1963, a typical car—which ran on leaded gasoline without pollution control devices— emitted 520 pounds of hydrocarbons, 1,700 pounds of carbon monoxide, and 90 pounds of nitrogen oxide every 10,000 miles traveled. More than 20,000 Americans died prematurely in 2015 from tailpipe emissions, according to a 2019 study.

This is partly because hydrogen production is energy inefficient and––when derived from fossil fuels––still a significant source of carbon emissions. All this is not to say there is no place for hydrogen in a clean energy future. Inefficient end uses for hydrogen can further exacerbate this problem.

The majority 6–3 decision sharply curtails the EPA’s authority to set standards based on a broad range of flexible options to cut carbon emissions from the power sector—options such as replacing polluting fossil fuels with cheap and widely available wind and solar power coupled with battery storage. carbon emissions today.

Last month, the Environmental Protection Agency (EPA) proposed new power plant carbon pollution standards that, if strengthened, would go a long way to help meet the Biden administration’s goal of slashing carbon emissions in half from 2005 levels by the end of this decade. EN: First, why are these new standards such a big deal?
