The core principle of HyESS-R is based on a high-efficiency "Power-to-Gas-to-Power" closed-loop cycle designed to eliminate the seasonal constraints of renewable energy.
The system achieves spatiotemporal energy shifting through a multi-energy coupling architecture: during the charging phase, a PEM electrolyzer converts surplus solar power into hydrogen, which is then pressurized to 30MPa for secure storage within the hydrogen units. This process transforms intermittent solar energy into stable chemical energy for long-term sequestration.
During the discharge phase, the system utilizes a dual-stage response mechanism: a battery string manages daily short-cycle fluctuations, while the fuel cell module serves as the backbone for long-duration energy storage. In periods of low solar irradiation or winter seasons, the stored hydrogen is released to generate stable electricity and 60°C thermal energy. By leveraging this sophisticated hydrogen-battery synergy, HyESS-R effectively overcomes the volatility of renewables, ensuring 100% energy independence and zero-carbon autonomy for users under any climatic conditions.
