Commend Ohio State University for New Carbon Capture Research

Carbon Capture Researcher

Target: Governor of Ohio, John R. Kasich

Goal: Commend Ohio State University researchers for work on new carbon dioxide capturing technology.

Researchers at Ohio State University have recently completed over 200 hours of successful continuous operation of their new patented Coal-Direct Chemical Looping (CDCL) technology. This is a process in which electricity and high-purity carbon dioxide are produced in a single-step procedure, enabling the immediate capture of this CO2 before it escapes into the atmosphere. Commend the OSU researchers for their work on this renewable technology, helping to keep our natural environment clean.

The 200 plus hours of operation represent the longest consolidated operation of any chemical looping system in the world. Project testing was led by OSU Professor Liang-Shih Fan. Operations were conducted at the university’s 25KW thermal CDCL combustion facility under the support of the Department of Energy’s (DOE) Carbon Capture Program. This series of measures encourages the development of new state-of-the-art environmental control technologies to enable cleaner use of the nation’s vast untapped coal reserves. The goal of the program is to develop CO2 compression and capturing systems that will reduce the cost and energy penalty of CO2 capture by more than half when installed at new plants. This means the capture must cost less than $40 per metric ton. OSU’s successful testing of its CDCL facility represents a step closer to full-scale chemical looping.

Chemical looping offers several benefits over traditional combustion methods. A metal oxide, such as iron oxide, provides the oxygen required for burning of the fuel. The oxide is placed into a chamber with a reducing atmosphere, which causes it to release its oxygen so it can react with the fuel. The reduced metal is then cycled back into another chamber where it regains its oxygen molecules by contact with outside air and returns to oxide form. CO2 separation occurs at the same time as coal conversion, so this system offers a low-cost opportunity for carbon capture. The CDCL process can produce electricity, synthesis gas, or hydrogen as well as high-purity CO2.

The development of this new technology by OSU researchers is highly beneficial to the nation. It allows the United States to make use of its coal reserves in a clean and efficient manner while preventing the release of carbon dioxide into our atmosphere. The electricity and gas it generates represent the advancement of green energy systems as the world works to integrate sustainable technology into every aspect of our lives. Sign this petition to ask Ohio Governor John R. Kasich to commend these researches for their valuable work.

PETITION LETTER:

Dear Governor Kasich,

Researchers at Ohio State University recently completed the longest successful operation of any coal-direct chemical looping (CDCL) technology in the world. This is innovative technology which makes carbon capture much easier while outputting useful energy.

Here is how it works: A metal oxide, such as iron oxide, provides the oxygen required for burning the fuel. The oxide is placed into a chamber with a reducing atmosphere, which causes it to release its oxygen so it can react with the fuel. The reduced metal is then cycled back into another chamber where it regains its oxygen molecules by contact with outside air and returns to oxide form. CO2 separation occurs at the same time as coal conversion, so this is how the system offers a low-cost opportunity for carbon capture. The CDCL process can produce electricity, synthesis gas (useful for a variety of fuels including synthetic natural gas), or hydrogen as well as high-purity CO2.

Development of chemical looping is important because it recycles valuable materials while localizing the CO2 release to make for easy capture. It allows for generation of clean, sustainable energy while ensuring that no emissions are released into the atmosphere. It also is beneficial to the Department of Energy’s recent Carbon Capture Program, which intends to reduce the cost of carbon capture by more than half. I urge you to commend the OSU researches for the work on chemical looping technology to ensure our environment remains clean and safe.

Sincerely,

[Your Name Here]
