”As more renewable energy is added to the electric grid, energy storage becomes a high priority. Suggestions have been made for energy storage in the form of fuel and chemicals. Currently, Solid Oxide Electrolysis systems can operate in endothermic mode and reduce the electrical requirement by supplying heat. Fuel synthesis from syngas is exothermic and can supply heat. However, the temperature mismatch in the normal operation of the electrolysis step and fuel synthesis step makes the direct utilization of this heat impossible. This work explores possibilities of alternate arrangements of coupling electrochemical systems and chemical synthesis. This work also explores potential for heat integration between the electrolysis and synthesis steps. This is done through exploring higher temperature fuel synthesis systems, and a new intermediate temperature electrolysis system.
The successful use of a Mo₂C/HZSM-5 catalyst for ethylene production is shown. Analysis of potential benefits and limitations of each technological approach are examined. The breakeven carbon pricing for the hybrid energy system production of chemicals to be competitive with fossil-fuel based chemical production is calculated”--Abstract, page iii.
