Abstract

Abstract: A novel cogeneration system of hydrogen and power is designed to solve the energy storage problem faced by both photovoltaic and solar thermal generation technologies. In this system, solar energy collection, photovoltaic generation, solid oxide electrolysis cell (SOEC) and solid oxide fuel cell (SOFC) are synergistically combined. A simplification of solar insolation curve was made before thermodynamic calculation. Based on the simplification, it shows that 1 MW system consists of 8.407 MW photovoltaic system, solar thermal collector with heating power of 6.756 MW, SOEC system with hydrogen produce rate of 0.0698 kg/s and 1 MW SOFC system. Power generating efficiency can reach 9.4% throughout the day, which partly demonstrates the feasibility of the system. In addition, oxygen can be produced in the system, which can be further utilized. Moreover, high temperature steam electrolysis which significantly reduces the electric energy consumption, provides a potential pathway for the interconversion of electricity and hydrogen. This method can be used to stockpile the electrical energy harvested from fluctuant renewable energy sources.

Key words: photovoltaic generation, solar thermal generation, solid oxide fuel cell, solid oxide electrolysis cell, solar hydrogen production
