HyESS-R series residential hydrogen energy storage system can help residential users achieve 100% of the year from their own solar energy system to obtain the function. It is truly energy self-sufficient, even in winter.
The system uses excess solar power from residential rooftop solar systems to convert water into hydrogen by electrolysis. Users can use hydrogen for long-term storage. On rainy days, the system efficiently converts hydrogen into electricity and heat.
During daylight hours in summer, the HyESS-R series residential hydrogen energy storage system first stores rooftop solar power in batteries. Excess rooftop solar electricity is converted into hydrogen by electrolyzers and stored for winter use. Even the waste heat generated is stored in hot water tanks, ready for use.
At night in the summer, users can use battery-stored electricity to power their homes. The heat from the hot water tank can also be used by you.
At all times during the winter, solar energy is not enough. Seasonal energy storage can ensure that users' homes get the electricity they need. With the help of fuel cells, hydrogen generates electricity while also generating heat to heat the user and reduce heating bills.

In residential fuel cell CHP applications, fuel cells are usually installed in the garage or basement of the building, and the heat generated by the fuel cell can be used for heating and hot water. By using natural gas and hydrogen as fuel, electricity generated by the H2ES and CarNeu series systems can be used for home lighting, air conditioning, televisions, computers, etc., as well as to charge devices such as electric vehicles.The use of fuel cells in residential applications can not only reduce the use of traditional fossil fuels, but also reduce the emission of greenhouse gases and other pollutants, which is very beneficial to environmental protection. At the same time, fuel cells can provide backup power supply for residential use in case of power failure, so as to ensure the normal operation of household appliances.
