After court blocks renewables push, US promotes carbon capture & hydrogen

Photosynthesis: nature requires carbon dioxide

The Environmental Protection Agency will set limits on power plants’ emissions, forcing them to ‘clean up’ (as they erroneously describe it) or shut down. But carbon capture is energy-intensive and expensive, so the idea doesn’t really work – hence the very low or often non-existent level of adoption even in climate-obsessed countries, and burning hydrogen has its own scientifically proven pollution issues, contrary to popular belief.

The Biden administration unveiled a sweeping plan to slash greenhouse gas emissions from the nation’s power industry on Thursday, one of the biggest steps so far in its effort to decarbonise the American economy to fight climate change, says Climate Home News.

The proposal would limit the amount of carbon dioxide that power plants, which are the source of more than a quarter of U.S. emissions, can send into the atmosphere, putting the industry on a years-long course to install billions of dollars of new equipment or shut down.

Environmental groups and scientists have long argued that such steps are crucial to curb global warming, but fossil-fuel-producing states argue that they represent government overreach and threaten to destabilise the electric grid.

The Environmental Protection Agency projects the plan would cut carbon emissions from coal plants and new gas plants by 617 million tonnes between 2028 and 2042.

That’s around 44m tonnes a year, about the same as the nation of Denmark pumps out.

CCS or hydrogen

The proposal sets standards that would push companies to install carbon capture equipment that can siphon the carbon dioxide from a power plant’s smokestack before it reaches the atmosphere, or use super-low-emissions hydrogen as a fuel.

“EPA’s proposal relies on proven, readily available technologies to limit carbon pollution and seizes the momentum already underway in the power sector to move toward a cleaner future,” Administrator Michael Regan said in a statement.
