carbon reduction

Across the country, states are inking agreements with neighbors or striking out on their own to pursue billions in federal funding to set up “hydrogen hubs,” clustered centers for production, storage and use of the gas that many see as a crucial piece of the puzzle for decarbonizing the U.S. economy. How broad a role it should play, however, is a matter of debate.

For the better part of the past century, the American electric power system evolved around large, mostly fossil fuel power plants delivering electricity to residences, businesses and industry through a network of transmission and distribution wires that collectively came to be called the electric grid. But as the threat of climate change driven by carbon pollution becomes more dire and as technological advances make wind, solar and battery storage ever cheaper options for powering homes and business, states, corporations and voters are increasingly pushing to aggressively decarbonize the grid.

Duke Energy's proposed carbon reduction plan calls for steep cuts in carbon dioxide, a major greenhouse gas, but does not decrease other types of emissions that drive climate change, according to filings with the state Utilities Commission. House Bill 951, now law, directed the state Utilities Commission to "take all reasonable steps" to reduce carbon dioxide emissions from Duke Energy: 70% from 2005 levels by the year 2030 and to achieve carbon neutrality by the year 2050.
