Flexible Carbon Capture Workshop

Crystal City Marriott - Reagan National Airport

Arlington, VA

July 30-31, 2019

ARPA-E sought information regarding the role of flexible carbon capture in terms of plant- and grid-level performance, economics and emissions. This workshop focused on the impact of a growing share of renewable generation on conventional power plants equipped with carbon capture and storage (CCS) systems. Future natural gas combined cycle (NGCC) plants, for example, will ramp their output, turn down to a low level, operate at a reduced capacity factor, and experience increasing fluctuations in locational marginal price signals.

Leading experts in carbon dioxide capture technologies and controls, plant- and grid-level modeling and techno-economic analysis, as well as materials scientists, chemists, and chemical, mechanical, and systems engineers, convened to explore how the design and operation of CCS systems could be modified to lower the cost of capturing COgiven such constraints. Participants lent their expertise to help ARPA-E explore innovative technologies to determine relevant and compelling metrics that will define a successful research program.

The workshop featured presentations related to changes in the grid, power plant flexibility, prior work on flexible CCS, and modeling and optimization tools. It included breakout sessions to brainstorm potential solutions and what types of research tasks (e.g. what level of modeling and simulation) are warranted at this time. The workshop also considered related topics, such as integration of energy storage, applicability to capture from industrial sources, and potential synergies with direct air capture systems.

ARPA-E Program Director Dr. Scott Litzelman recently developed a helpful webinar on flexible CCS, a recording of which can be found below.

The meeting's output will help direct the actions of ARPA-E towards the most promising and appropriate high risk, high return R&D funding opportunities and management strategies. This event was closed to the media.
