This study uses detailed process models for heat generated from sedimentary basin geothermal, concentrated solar, and a heat pump to generate geospatial results across the US, and explores the key parameters that make each energy source preferred. The authors use sorbent-based direct air capture (DAC) as a case study heat application and examine both the levelized cost of heat (LCOH), and the levelized cost of carbon removal (LCOR).
