Founded in 2016, Duma Energy’s mission is to make renewable energy reliable by delivering the world’s most flexible, most durable energy storage systems. The combination of low-cost renewable power generation and our Duma Energy vanadium redox flow batteries deliver electricity on demand, 24 hours a day, at a lower cost than conventional sources.

Duma Energy offers a Battery Systems with a nominal power rating of 5 kW and a storage capacity between 15 and 45 kWh. This makes the battery a perfect solution for private homes, small to medium-size businesses, either off-grid or as a backup system. Based on the powerful Vanadium Redox Flow Technology the compact design allows fast installation and safe operation.

The Duma Energy Battery Systems enables you to store the energy produced by photovoltaics, wind turbines or any other source. It makes it possible to use the stored energy whenever it is needed – any time of the day or in case of a grid failure. You can be more independent of fluctuating electricity prices and use the renewable energy that you produce.

TIA is a national public entity that serves as the key institutional intervention to bridge the innovation chasm between research and development from higher education institutions, science councils, public entities, and private sector, and commercialisation. TIA’s focus is on technology development; from proof of concept to pre commercialisation. To achieve this, TIA established the following funds: the Seed Fund, the Technology Development Fund, and the Commercialisation Support Fund.
