Hide DetailsDelta Green is the first energy-independent office building in France, with energy production exceeding user consumption. The aim of Delta Green is to showcase complete energy autonomy. The energy mix is made up of PV, geothermal and hydrogen storage; with PowiDian integrating the hydrogen solution. Instead of using batteries, the tertiary building uses 2 Enapter electrolyzers to store hydrogen for peak shaving. This avoids spikes in electricity by converting hydrogen into electricity to fulfil demand, as well as saving on electricity costs which would have been more expensive. Additionally, the excess PV during summer is stored as hydrogen and used in the winter. The passive house building has a low CO2 footprint across lighting, heating, and cooling systems.
The innovative building was the winner of the Green Solutions Award 2018, which recognises architecture that is mindful of the environment and contributes to the fight against climate change. Enapter is proud to be involved in such a pioneering project for electricity storage.
