This newly launched system that produces green hydrogen at home wants you to stop worrying about the electricity bill
The German company Picea has launched its new electrolyzer with which they promise to be able to generate clean electricity at home, as long as they already have a photovoltaic installation at home.
With the energy produced by sunlight , the company’s module is capable of producing green hydrogen that will be used to power the house, thus favoring its own self-consumption and moving away from the grid.
It is a system that is capable of producing and storing energy throughout the year and depending on the demand and need of the moment, as it can store energy to be used at times when sunlight is low, such as at night or in winter.
It allows to produce and store energy in an interrupted way
The Picea Power Center can be installed in a basement or a quiet place, which occupies 1.5 m², while the green hydrogen storage tank is installed outside the house.
The system has two working modes:
Short-term storage, which works day and night. With tried and tested battery technology, the solar energy of the day is stored and can be used at night. During the day, the sun charges the battery so that there is enough solar energy available at night.
Long-term storage, for summer and winter. To compensate for the lack of solar performance in winter, spruce uses hydrogen. Spruce uses excess electricity in summer to make hydrogen from water. In winter, this process is reversed and electricity is generated again from hydrogen. Storage and use are completely emission-free.
The Picea system for water treatment and electrolyzer for hydrogen production includes :
- Fuel cell to convert hydrogen back into electricity.
- Battery with a capacity of 20 kWh for short-term storage
- Inverter and solar charge controller for connection to a photovoltaic system
- Heat recovery ventilation system for a better living climate and heating relief.
All components are controlled and supervised by intelligent energy management.
This is an expensive system, as the price of a spruce ranges from € 70,000 to € 100,000 gross (depending on individual design) including a 10-year warranty. To this, we must add the costs of the service contract are 499.80 euros gross per year.
