A Physics‐Based, Lumped‐Parameter Model for Attributing Natural and Anthropogenic CO2 Emissions From Producing Geothermal Systems

open access: yesWater Resources Research, Volume 62, Issue 9, September 2026.
Abstract Although geothermal energy is a low‐carbon resource, some powerplants can coproduce and release CO2 ${\text{CO}}_{2}$, which is then subject to emissions monitoring and sometimes financial penalty. Accurate attribution of these emissions is difficult because exploitation of the reservoir alters hydrological flows that in turn modify surface ...
