Isotherm Energy is developing a system architecture for addressing these challenges that provides energy storage and potable water production. The architecture enables tailoring of system parameters to meet specific application requirements using current and emerging technologies.
Isotherm's hydrogen-based system accepts inputs from a variety of energy (solar, wind, etc), non-potable water (saltwater, wastewater, etc.), biomass and other sources. The selected inputs are used to produce hydrogen to be stored for later use. Oxygen and other beneficial byproducts are also produced depending on the water and/or hydrogen feedstocks used. Power is generated when needed from the stored hydrogen via fuel cells, turbines, internal combustion engines or other combustion processes. The resulting outputs are electrical or kinetic energy and potable water.
Roundtrip efficiency of the system is optimized by incorporating heat recovery in the form of waste heat harvesting, combined heat and power (CHP), bottoming cycles and other combined cycles depending on the application. The production of potable water from non-potable sources also increases the effective performance of the system relative to separate energy storage and water processing systems. The architecture is scalable to a wide range of applications including:
- Microgrids and onsite water processing
- Desalination and energy storage
- Transportation systems
