Our energy system is designed to store solar power in the most efficient and ecological way. The hybrid hydrogen - battery system maximizes the advantages of both the hydrogen storage system and battery storage system. The energy of the sun is transformed via solar panels in to electricity. Excess power is converted and stored as hydrogen. The stored hydrogen gas in tanks generates electricity by using fuel cells.

SUMMER (during the day)

On sunny summer days, Picea stores the solar energy in a battery. The excess solar electricity is converted to hydrogen using the electrolyzer and stored for later use during wintertime. Even the waste heat created is stored in the hot water tank ready for use when it is required.

SUMMER (in the evening)

After sunset, you can use the stored electricity of the battery to supply your household as usual. The stored heat of the hot water storage tank is also available to you.

Seasonal Storage

WINTER (during the day)

Since solar energy alone is not sufficient during winter, your seasonal storage ensures your home is supplied with electricity as needed. This is done with the help of a fuel cell which also generates heat and works in addition to your heating appliance.

WINTER (in the evening)

If there is no solar energy at your disposal, your household is served by the seasonal storage in winter. The fuel cell uses hydrogen to produce electricity and heat for you. A controlled humidification of the room air additionally increases the comfort and ensures a healthy coziness.
