Technology Description:

Susteon will evaluate a CO2 capture technology using solid sorbents based on thermal swing adsorption that enables power generators to operate the power plant in a "load following" mode in response to grid conditions in a high VRE penetration environment. The proposed capture technology, based on novel structured adsorbents incorporating advanced nanomaterials, is currently being demonstrated with flue gas derived from natural gas combustion. Susteon plans to simulate the integration of this technology with an existing natural gas power plant in southern California, a region with a large amount of renewable electricity on the grid. This integrated model has the potential to maximize the power plant’s net present value operation in a high VRE penetration environment.

Potential Impact:

Improvements in the design and processes of CCS-equipped plants in high VRE environments could dramatically reduce the cost of a net-zero carbon system. Benefits include:


Flexible CCS systems can enable the continued use of low-cost domestic fuel for electricity generation and increase the reliability of a deeply decarbonized electricity system.


Flexible CCS systems can achieve high CO2 capture rates from flue gas. Enabling deep turndown of natural-gas fired plants at times of high VRE output will reduce fuel consumption and CO2 emissions.


Flexible CCS systems can reduce the cost of a net-zero carbon electricity system by providing dispatchable power to a high-VRE grid.
