HPS expands its product range by introducing storage systems for businesses and multi-family houses

  • Year-round multi-picea electricity storage system can store up to 15,000 kilowatt hours of solar electricity
  • Cascaded storage units enable flexible performance and storage capacity
  • First commercial property equipped with multi-picea in Meckenheim


Berlin, 7 December 2021 – HPS Home Power Solutions GmbH (HPS), provider of picea, the green hydrogen-based, year-round electricity storage system for buildings, today announced that it has expanded its product portfolio. The newly developed “Förster” control and energy management system now allows up to ten picea units to be interconnected. This “multi-picea” set-up can now supply solar power to buildings with larger power requirements, such as commercial properties or apartment buildings, from their own roof all year round. Multi-piceas have a storage capacity of up to 15,000 kilowatt hours electric.

HPS is constantly working on expanding the performance of its products and opening up new market segments. The cascading approach used by multi-picea allows both performance and storage capacity to be adjusted for different applications. By using the same standard picea unit, additional scale effects in production are achieved resulting in lower manufacturing costs going forward.

“By developing multi-picea we have responded to a strong demand in this sector and created a solution that offers higher storage capacity and performance in larger buildings. This enables consumers in commercial properties and multi-family houses to fully utilize their own solar power even in winter by flexible scaling of our proven year-round electricity storage system,” said Zeyad Abul-Ella, Managing Director and co-founder of HPS. “Our multi-picea solution is yet another contribution to decarbonizing the building sector.”


First multi-picea installed in Meckenheim

Josef Küpper Söhne GmbH from Meckenheim is the first customer to equip a commercial property in Germany with a multi-picea system. Five picea units store the surplus solar power produced by the 98‑kilowatt peak solar system installed on the roof and facade of the company’s new building, thus covering the electricity and heat requirements even in winter. “We are pursuing an independent and clean energy supply both for our customers and for ourselves, because the time is ripe to move toward a carbon-free society. That is why we opted for the multi-picea long-term storage system from HPS when we designed our new site in Meckenheim,” said Peter Küpper, Managing Director of Josef Küpper Söhne GmbH.


About picea

picea is the world’s first hydrogen-based electricity storage system for one and two-family houses. The Förster product extension allows picea units to be cascaded to meet even larger power and storage requirements. 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 year-round, carbon-free full power supply and also reduces heating costs.


How multi-picea works

A central control and energy management unit called “Förster” (German for forester) establishes communication between the individual picea units, distributes energy evenly and records the building’s energy flows. Förster enables the individual picea units to work together in one application, the multi-picea solution. picea is the Latin term for spruce. One picea avoids about three tons of carbon dioxide per year. This corresponds to the amount of carbon dioxide bound by 130 spruce trees per year. Förster can manage up to ten picea units. The intelligent energy management provided by Förster distributes the storage of solar energy in summer and the power output in winter to the individual systems as needed, which ensures the longevity of the individual modules.


About HPS Home Power Solutions

HPS develops and produces integrated systems for the storage and use of solar energy for one- and two-family houses. The Förster product extension allows picea units to be cascaded to meet even larger power and storage requirements. HPS offers green hydrogen-based solutions for decarbonizing the building sector. The Berlin-based company was founded in 2014 by Zeyad Abul-Ella and Dr. Henrik Colell and stands for reliability, independence and sustainability in decentralized energy supply. picea, developed by HPS, is the first system worldwide that combines electricity storage, heating support and residential ventilation in one compact product. One picea system avoids approx. three tons of carbon dioxide per year, binding as much carbon dioxide as 130 spruce trees. picea has won several prestigious awards, most recently the Handelsblatt Energy Award 2020, the Smarter E Award 2021 and the Berlin Brandenburg Innovation Award 2021.
