QUalitative Electricity STorage for Solar energy


Lancey Energy Storage is pioneering a new era for energy storage, in which home appliances can contribute to the energy transition by storing electricity and engaging citizens.
To fight global warming, renewable energy (RE) production is soaring, which is good news but has direct consequences on network management due to the intermittency of solar and wind power. Distributed storage can help better regulating the power grid and integrating more RE through self consumption and grid services. But few can afford it. Lancey aims at democratizing it by embarking a battery into a space heater. In France alone, 1/3 of real estate is electrically heated. Yet 1st generation electric heaters consume a lot of electricity and are highly responsible for the evening winter power peaks. Lancey has the solution to both of these issues. With its efficient heating technologies and energy management system, Lancey heater fine tunes to users’ needs while its battery charges off peak or with renewable energy surplus and discharges to prevent it from consuming power during peak hours. Total heating bill reduction can reach up to 50%. In 1,5 year of existence, Lancey has put on the market an innovative patented product rewarded by a CES Best innovation award. Yet this first version of the Lancey heater is still limited as its battery can only be used to power the heater.
Solar QUEST’s purpose is to develop the V2 of Lancey heater, able to reinject power stored in the battery into buildings’ grid to power other devices. It will unlock Lancey’s participation to grid services and make it possible to maximise PV installations’ self consumption rate in summer too. With its Danish partner Tomorrow, Lancey will showcase the CO2 emissions its offsets, better engage users on energy transition and integrate self-consumption and grid services parameters into Lancey’s management algorithms. Lancey will perform pilot demonstrations of this new product in France, Canada and Finland with key partners.
