Technology Description:

Arizona State University (ASU) is developing an innovative electrochemical technology for capturing the CO2 released by coal-fired power plants. ASU’s technology aims to cut both the energy requirements and cost of CO2 capture technology in half compared to today’s best methods. Presently, the only proven commercially viable technology for capturing CO2 from coal plants uses a significant amount of energy, consuming roughly 40% of total power plant output. If installed today, this technology would increase the cost of electricity production by 85%. ASU is advancing a fundamentally new paradigm for CO2 capture using novel electrochemical reactants to separate and capture CO2. This process could be easily scaled and integrated in conventional fossil fuel power generation facilities.

Potential Impact:

If successful, ASU’s electrochemical technology would reduce the cost of capturing CO2 by 50% compared to existing processes and establish a new manufacturing industry for large-scale applications.


Enabling continued use of domestic coal for electricity generation will preserve the stability of the electric grid.


Carbon capture technology could prevent more than 800 million tons of CO2 from being emitted into the atmosphere each year.


Improving the cost-effectiveness of carbon capture methods will minimize added costs to homeowners and businesses using electricity generated by coal-fired power plants for the foreseeable future.
