Summer: During the day, the energy surplus of the photovoltaic installation is used to firstly charge a lithium battery storage to cover the night electricity demand. After reaching a sufficient charging status, the electrolyser starts to produce hydrogen which is compressed and stored in a tank for long-term storage.
	Winter: The stored hydrogen supplies a fuel cell to generate electricity to charge the battery system as well as providing electricity to the building power network. The waste heat of the water-cooled fuel cell supplies a heat pump to ensure the building heating.

Application Scenario 2：Commercial Office Building-Low Carbon Office Building


In this modern commercial office building,the advanced clean energy technology of the Smart H2 Energy Platform is installed to achieve an integrated

energy supply solution for photovoltaic, lithium-ion batteries and hydrogen energy. During the day, the electricity generated by the photovoltaic system is directly used to power the building, including lighting, air conditioning, and various office equipment. The surplus electricity is stored in lithium-ion

batteries, or used to produce hydrogen by electrolysis of water. The hydrogen can be used to generate electricity at night, and also through the winter.
