Fuel cells works, Home Power Solutions Collaborates With Wohnwerke to Install Picea Solar-Hydrogen Systems in Private Homes

Berlin — Berlin-based HPS Home Power Solutions GmbH and builders and architects Wohnwerke GmbH are launching a partnership for climate-friendly, private houses.

  • Wohnwerke will be offering private homes with the picea energy storage system from HPS under the neubauten brand
  • picea is the world’s first commercially available CO2 free, solar-hydrogen-based power supply for private homes
  • First joint show house planned near Stuttgart

Wohnwerke will offer its customers picea, the hydrogen-based electricity storage system from HPS, as standard equipment for their one-family homes. The combination of modern architecture and innovative energy system is planned to be built soon in a show house in Asperglen-Rudersberg near Stuttgart.

Using solar energy and innovative power-to-gas hydrogen technology, picea enables a year-round, carbon-free and independent power supply for one- and two-family houses. HPS offers the first marketable solution worldwide in this segment. The picea system also uses the entire process of heat from energy generation, storage, and usage to reduce the energy required to heat a house. picea has a very high overall utilization rate of around 90%.

picea offers more than 100 times the storage capacity of home batteries available on the market today. The system enables hydrogen technology to be used easily and efficiently in private households for the first time and can thus make a significant contribution to climate protection. The show house will underline the technological market leadership of HPS as well as the commitment and reliability of picea. It demonstrates Wohnwerke’s ambition to equip high-quality homes with an independent power supply and contribute to climate protection.

Zeyad Abul-Ella, Managing Director of HPS Home Power Solutions, comments: “After the successful start of production of picea, we are very pleased to announce an attractive partner for the distribution of our innovative storage system. Wohnwerke stands for high-quality, modern, and ecological living design and therefore fits perfectly with our forward-looking and practical energy solution.“

Lucas Neddermann, managing director of Wohnwerke, adds: “Our customers are quality and environmentally conscious and are looking for climate-friendly living solutions. We are therefore very pleased to have found the partner with the innovative picea system with whom we are able to realize an energy self-sufficient building. Together with HPS, we are taking a pioneering role in the future market of hydrogen-based energy storage in private homes.“

About picea

picea is the world’s first hydrogen-based electricity storage system for one and two-family houses. The energy surpluses achieved on sunny days from a photovoltaic system are stored as green hydrogen to make electricity and heat available in the dark season. picea provides a year-round, carbon-free full power supply and also reduces heating costs. One picea system avoids approx. 3 tons of carbon dioxide per year, binding as much carbon dioxide as 130 Spruce trees. HPS started delivering the first picea systems in 2019. With contract manufacturing having started in 2020, larger quantities are being produced and become available for delivery in 2021. picea has won several prestigious awards, e.g. the Handelsblatt Energy Award 2021.

Wohnwerke offers architect, planning and project development services from a single source. The unique selling proposition of the young company based in Remshalden near Stuttgart is to combine creative solutions with a holistic view of buildings and the highest quality standards for private homes. Under the neubauten brand, Wohnwerke GmbH has developed a house that supplies itself with heating energy and electricity. The successful implementation of the “economically self-sufficient” neubauten energy-plus house was followed up by the development of the “energy self-sufficient” new built power-to-gas house.
