New EPA Rule Is First Ever To Limit Carbon Emissions From New Power Plants

In a move that advances one of the key goals President Obama outlined in his Climate Action Plan last June, the Environmental Protection Agency published a new rule this week with the first-ever federal limits on carbon emissions from newly constructed power plants.

The EPA took four months to publish the rule in the Federal Register after EPA Administrator Gina McCarthy announced it in a speech last September. The rule sets sets separate standards for coal-fired and natural-gas-fired electricity generating plants.

Once in place, the rule will limit all future coal plants to 1,100 pounds of carbon dioxide emissions for each megawatt hour of electricity they generate. Today's coal-fired power plants pump an average of about 1,700 pounds of carbon dioxide into the air per megawatt hour.

Natural gas plants will be limited to 1,000 pounds of carbon dioxide emissions per megawatt hour for larger units (plants that generate 100 megawatts of energy) and 1,100 pounds of CO2 per megawatt hour for smaller plants.

Most coal plants won't meet the new standard without implementing cutting-edge technologies that capture and store their carbon emissions, which has stoked industry fears that these new regulations will effectively mean no new coal plants will ever be built in the United States.

U.S. Senator John Barrasso (R-Wyoming), who represents one of the nation's biggest coal-producing states, sharply criticized the EPA's action yesterday on Twitter:

 

The electricity industry is the largest source of greenhouse gas emissions in the U.S., and coal accounts for about 80 percent of its CO2 emissions each year.

But the coal industry also is one of the most important to the economies of states like Montana and Wyoming, which are expected to expand production this year after two years of declines.

In her speech last September (which you can watch in the video below), McCarthy answered critics by pointing to the car industry. "Those standards did not cripple the auto industry," she said. "They made it stronger and more competitive."

 

Currently no power plants in the U.S. use the technologies McCarthy refers to in the speech, known as carbon capture and storage (or carbon dioxide capture and sequestration), though a massive project to build a plant equipped with them is underway in Kemper County, Miss.

Projects to build plants with the technology also are in progress in Canada's Saskatchewan province, where an older coal plant is being retrofitted. The Texas Clean Energy Project is planned near Odessa, Texas, while Hydrogen Energy California will both use hydrogen to generate electricity and store carbon to enable oil recovery in Kern County, Calif.

The Massachusetts Institute of Technology's Carbon Capture and Sequestration Technologies project has compiled a database of all the CCS projects currently planned or already being built around the world, which you can see by clicking the icons in this Google map:

Just because the rule has been published in the Federal Register doesn't mean that it's yet in effect, however. The public has 60 days to comment on the rule – at the EPA website set up to receive input on the new carbon pollution standards, or at the public hearing scheduled for Jan. 28 in Washington, D.C.

Upgraded HWRF and GFDL Hurricane Models Excelled During Hurricane Arthur

By Dr. Jeff Masters
July 11, 2014

There have been major upgrades this year to the two operational National Weather Service (NWS) regional hurricane prediction systems, the GFDL and HWRF models. Both models did well for track and intensity forecasts for Hurricane Arthur, and the average intensity errors wer comparable to the other two top NWS intensity prediction models (LGEM and DSHIPS.)

Warmest Days of the Year for the U.S.

NOAA recently produced an interesting map showing when the hottest day of the year is likely to occur in the contiguous U.S. Complimenting this map is one produced by Brian Brettschneider of Borealis Scientific, LLC, which illustrates the date of summer’s midpoint (peak of summer average temperatures) which was reproduced in my blog posted last August. Brian has also produced maps of such for the Fall, Winter and Spring seasons. There is also some other great material from Brian herein.

What the 5th IPCC Assessment Doesn't Include

By Angela Fritz
September 27, 2013

Melting permafrost has the potential to release an additional 1.5 trillion tons of carbon into the atmosphere, and could increase our global average temperature by 1.5°F in addition to our day-to-day human emissions. However, this effect is not included in the IPCC report issued Friday morning, which means the estimates of how Earth's climate will change are likely on the conservative side.
