The Stockholm-based battery startup Enerpoly and the Graz-based smart photovoltaic startup Efficient Energy Technology have received €870,000 in grant funding under the Eurostars-3 program. The fresh funding will be spent to develop prototypes of a residential plug-in storage system with rechargeable zinc batteries in Europe.

  • Founded in 2018 Enerpoly develops zinc-ion batteries for stationary storage applications. They are suitable for short- to medium-duration storage applications of two to 10 hours. The company claims that Zinc-ion batteries can enable 100% renewable energy on a global scale.
  • EET was launched in 2017 and is developing solar plug-in storage technology. Its devices can be installed without the help of a technician. EET’s innovation core for the SolMate device, an integrated and patented measurement technology that can detect the energy demand of a household via a power outlet connection. Since launching, EET has sold over 10,000 units of its systems, with and without storage.
  • Eurostars is a funding program, backed by the European Union through Horizon Europe. It is the largest international funding programme for SMEs wishing to collaborate on R&D projects that create innovative products, processes, or services for commercialization. Eurostars is operated by EUREKA, an intergovernmental network involving 37 countries.

“Rising electricity bills and energy security are increasingly concerning issues for Europe. Everyone, whether homeowners or tenants, should have the ability to generate, store and access renewable energy without breaking the bank. ZincMate offers an affordable, safe, and easy-to-use energy generation plus storage product. By working with EET, we’re taking a decisive step towards making clean energy accessible to all,”

states Eloisa de Castro, CEO of Enerpoly.
  • The grant funding will be used for the development of the collaborative project ZincMate. The technical basis for ZincMate is EET’s on-grid technology in combination with Enerpoly’s cost-effective battery. The prototypes of a residential plug-in storage system will be tested in both laboratory and home environments. The project starts in 2023 and runs for 2 years.
