How Clean Coal May Make A Tidy Profit

How Clean Coal May Make A Tidy Profit

The current extension and expansion of a tax credit for carbon capture have many taking a second look at carbon seize applied sciences for many industries, together with power plants.

Because the program is designed as a carrot (tax credit) rather than a stick (carbon tax), essentially the most polluting crops have the most incentive to retrofit.

On condition that dynamic, will fossil fuel interests and environmental groups alike see this as a win-win?

In response to the Global CCS Institute, there are 17 giant Carbon Seize and Sequestration (CCS) items operating worldwide right now, with another 20 in varied levels of development. Of these, eleven are within the U.S., and just one, Petra Nova, is related to an influence plant. The opposite 10 U.S. facilities are related to chemical production and natural gasoline processing. Just one of many U.S. facilities sequesters CO2 for the long-time period and the other 10 use or promote the CO2 for enhanced oil restoration (EOR).

All of the energy plant with CCS projects on this planet utilize publish-combustion seize (the CO2 is removed after the fuel is burned), while some future crops are considering pre-combustion or oxy-fuel combustion seize strategies, every their very own relative advantages and disadvantages.

Passed as a part of the Federal budget, the tax credits are intended for power crops and industrial facilities that seize and sequester CO2 (or sell it for enhanced oil restoration, EOR) that would otherwise be emitted. Each will obtain up to $50 or $35/MT for 12 years.

These credits have received little fanfare, however they've potential to radically change the economics of some energy vegetation, and would possibly put some back within the black.

Using publically available datasets, we find that there are 27 existing coal and pure fuel combined cycle (NGCC) power vegetation in the U.S. within 10 miles of current CO2 pipelines. While retrofit applications (or new builds) could be present in different areas, close proximity to existing infrastructure provides some price advantages.

The ability crops are separated by region and type, with about 6,seven-hundred MW of coal vegetation between Oklahoma and Wyoming, and about 11,500 MW of NGCC vegetation in the New Mexico/Oklahoma/Texas/Louisiana region. If all of these power vegetation were to retrofit their existing amenities and capture ninety% of the CO2 they emit, they may preserve about 1 gigaton of CO2 out of the atmosphere over the 12-year credit lifetime, though other types of emissions could nonetheless be a problem.

The map under shows present CO2 pipelines in red, present Coal Contracting Services power plants (with 10 miles of the pipelines) in orange, and existing NGCC power crops in blue. The scale of the bubble signifies the nameplate capacity of the facility plant.
