Employing Variable Current/Voltage Control Schemes to Develop Carnot-Analogous Mixing Engines for Salinity Gradient Energy Extraction

Daniel A. Moreno
Proc. ASME. POWER2023, ASME Power Applied R&D 2023, V001T05A009, August 6–8, 2023
Publisher: American Society of Mechanical Engineers
Paper No: POWER2023-108772
https://doi.org/10.1115/POWER2023-108772
... Abstract A capacitive mixing engine is developed which follows four stages of operation analogous to those of a Carnot cycle. This work establishes and evaluates control schemes for cell voltage and current as functions of time to maintain cycling stages where a constant number of ions property...

Using Temperature Variations to Demonstrate Analogous Carnot Heat Engines for Salinity Gradient Energy via Capacitive Mixing

Daniel A. Moreno
Proc. ASME. POWER2022, ASME 2022 Power Conference, V001T07A006, July 18–19, 2022
Publisher: American Society of Mechanical Engineers
Paper No: POWER2022-85430
https://doi.org/10.1115/POWER2022-85430
... Abstract A proof-of-concept electrochemical analog for a Carnot cycle is developed using a capacitive mixing (CapMix) engine to extract electrical energy from a salinity gradient. Here, temperature is allowed to vary to assist in the development of such a cycle. The Gouy-Chapman-Stern model...
