Project Title Chemical Energy Carriers (CEC) for the Utilization of Geothermal Energy
Project Type / Topic 1 Laboratory Call for Submission of Applications for Research, Development and Analysis of Geothermal Technologies
Project Type / Topic 2 Working Fluids for Binary Power Plants

Project Description The Geothermal Technologies Program (GTP) is seeking to develop new and innovative technologies to advance the utilization of geothermal energy. The proposed process meets GTP’s goals because it could potentially double the power output of EGS power generation plants. The CEC process is a novel EGS heat storage and transport approach that will make heat available for power generation at higher temperatures. Because it is a closed-loop process, it also avoids SO2 and CO2 emissions and conserves water. The proposed process provides the power industry with a tool to reduce their emissions while cultivating the domestic EGS clean energy that is underutilized because of the lack of economical technology.

Principal Investigator(s) Bassam Jody


Targets / Milestones The work plan will be organized into the following six tasks:


- Task 1: Identify reversible reactions that could be used for recovering EGS heat from sources in the temperature range of 150–500°C, evaluate availability and limitations of materials including catalysts for implementation, and evaluate compatibility of these reactions with different EGS reservoirs (temperature, pressure, rock chemistry, etc.).
- Task 2: Conduct thermodynamic and process engineering simulation/analysis of the leading candidates to identify bottlenecks and evaluate design modifications and R&D needs for the application of CEC systems to EGS reservoirs available in the United States.
- Task 3: Determine thermodynamic targets for improvements in catalyst performance or development of new catalysts and associated process design modifications (e.g., in-situ separation of one or more of the products or by-products).
- Task 4: Conduct laboratory tests of CEC/available catalyst systems to confirm thermodynamic analysis and to test new catalysts and assess potential for success under simulated EGS conditions.
- Task 5: Develop, design, and analyze (chemistry, engineering, economics) CEC systems to match EGS temperatures, pressures, chemistry, and mineralogy with endothermic/exothermic cycle reaction conditions.
- Task 6: Develop a plan for field testing the leading candidate(s).
