Summary/Abstract
The comment reviews subsidies provided for solar energy to identify the growth of the solar energy as a whole. Specifically, the comment examines investment tax credits, federal grant money and loan guarantee programs under the Energy Policy Act. The comment notes a clear correlation between subsidies and growth in technology, specifically highlighting the impact of investment tax credits.
Applying these lessons to direct air capture, the comment notes the challenges to the industry, and examines subsidies prior to and post the passage of the Inflation Reduction Act. The comment then parallels the solar industry and its subsidies to the direct air capture industry, observing potential roadblocks and causes for optimism.
