Technology demonstration of large scale photo-electrochemical system for solar hydrogen production - PECSYS
Solar driven hydrogen generation via water electrolysis is an archetypal use of renewable energy that ensures a sustainable energy supply while minimizing greenhouse emissions. The challenges for adaptation by society are the high cost of the technology and maintaining the reliability of supply compared to conventional energy from fossil fuels.
State of the art photovoltaic (PV) – electrochemical (EC) systems use a separate PV module array, which is connected by wires to the EC electrolyser. However, where restrictions on footprint apply, integrated wireless PV-EC water electrolysis systems are an attractive solution. Up to date, integrated wireless PV-EC water electrolysis has only been demonstrated on a laboratory scale.
The PECSYS project aims at demonstrating an operational PV-EC system measuring at least 10 m² with a solar to hydrogen (STH) efficiency of at least 6 % supporting a hydrogen production of at least 16 g/h at a levelised cost of 5€/kg. The system is also expected to operate continuously under outdoor conditions with an STH efficiency loss of less than 10% relative after six months.
