The Solar Impulse foundation has just selected the innovative Be Greener solution set up by Bouygues Energies & Services and Powidian for the Air Navigation Services Department (DSNA). Via local green hydrogen production, this solution ensures the energy autonomy of isolated sites.
This innovative solution was developed at the instigation of the DSNA within the framework of the SEPHER project “Electric Relief by Hydrogen Battery and Renewable Energies” for the supply of an antenna. This system received the Efficient solution distinction and is included in the top 1000 solutions for a sustainable future by the Solar Impulse Foundation. The Solar Impulse Foundation was created with a single goal: to promote clean and profitable solutions to decision makers around the world.
This label is awarded to innovations that are currently in operation with a positive socio-environmental impact and economic profitability. Be Greener is therefore now one of the 1000 solutions that are promoted and presented by Bertrand Piccard to governments, companies and institutions around the world.
Storage of green energy, a key issue for the future of the planet
One of the key challenges of our future energy supply system is the storage of renewable energy. It balances production and demand and will therefore be the key to an intelligent, resilient and autonomous energy network. Be Greener, an environmentally friendly solution, aims to replace diesel generators with a solution based on green hydrogen , local and produced from renewable energy. The energy stored by this hydrogen installation is used to supply isolated sites.
In the application of the SEPHER project, energy is produced locally by photovoltaic panels to supply the antenna. Part of this energy is transformed into hydrogen thanks to an electrolyser. This green hydrogen is stored to cope with a possible supply deficit over a period of 1 to 5 days. The hydrogen can then be transformed back into electricity, using a fuel cell.
In the same reference configuration, the consumption of non-renewable primary energy will thus be reduced by 78% and greenhouse gas emissions by 79% compared to a conventional diesel generator solution.
“We are very proud that the fruit of our collective work, Be Greener with Powidian for the DNSA, is recognized by the Solar Impulse foundation among the 1000 innovative technological solutions, in the world, to develop clean and local energies.”
