CO 2 -free and energy self-sufficient – with the decentralized energy system Picea from HPS, solar energy is converted into green hydrogen. Homeowners can use the system to generate and store renewable energy themselves and thus supply themselves all year round.
Users also have full transparency about consumption and costs. GASAG is cooperating with HPS to develop an emission-free and sustainable offer for home customers.
With the Picea system, HPS has developed a system for single-family houses in which the latest energy technologies work together efficiently: solar power system with charge controller and inverter, battery, electrolyser, fuel cell, and ventilation unit. GASAG has installed the first PICEA system at a customer and is thus building up expertise in the installation and operation of hydrogen systems. The energy service provider thus continues to pursue the goal of contributing to a CO 2 -neutral future for the Berlin-Brandenburg region.
With a PV system on the roof, solar power is generated, which can either be used immediately, stored in batteries or converted into hydrogen using an electrolyser. This green energy is then available all year round for its own power supply in its own hydrogen storage facilities. The waste heat generated during system operation is also used for hot water or heating. This also reduces energy consumption and thus energy costs.
Hydrogen can be generated from water by electrolysis. Electrolysis uses electricity to break down water into the elements hydrogen and oxygen. If renewable electricity is used, the hydrogen is CO 2 -free. In this case, green hydrogen is often spoken of. This can be saved and used with the help of a fuel cell for further power and heat supply.
