Sylfen develops hybrid energy storage solutions called Smart Energy Hub, combined with real-time software mangement system, to render buildings and ecodistricits self-sufficient in carbon-free energy.
Established in 2015, Sylfen develops an energy storage system for buildings and eco-districts, the Smart Energy Hub. At the heart of this product Sylfen implements the Solid Oxide Cells (rSOC) technology, benefiting from 12 years of R&D, 40 million euro and 22 patents granted, whose successful implementation on a pilot plant in 2014 was a worldwide record performance in electrolysis. This technology is combined with batteries and a multi-energy software control system optimized for each building. This technology is capable of generating hydrogen from water electrolysis, and to provide back heat & power from hydrogen (or bio-methane). This breakthrough technology is provided with a powerful real-time software management system, to make the best energy supply choices throughout the year (anticipating energy consumption, weather, habits, comfort, etc.). With both power (batteries) and capacity (hydrogen) energy storage capabilities, we can dramatically increase auto-consumption to near-zero energy buildings or ecodistricts, and reach energy self-sufficiency. Our business model is multiple : we sell energy consultancy services, we sell Smart Energy Hubs, on top of which comes a monthly subscription to get advanced reporting and predictive maintenance. As such, both building owners and their energy operators benefits from this innovation. Additionally, this product helps stabilize electric networks, that can suffers from renewable energy production sources (intermittent by nature), by offering an alternative to grids injections. Rather, we can store locally excess from surrounding buildings, and provide back electricity from our Smart Energy Hub to the whole surrounding ecosystem. Potentially, if there are too much hydrogen at a given time that buildings can’t handle, the carbon-free hydrogen can power cars or bus to offer clean mobility to citizens. We have received our 1st order for an integrated prototype from a large French company, that will be shipped in the first quarter of 2018. In parallel we are preparing a series of real scale demo products that will be connected to demonstrator buildings end of 2018 through 2019 to validate business cases.
Hybrid energy storage solution for autonomous buildings
Sylfen develops smart energy hubs that operate in a reversible manner, either as an electrolyser or as a fuel cell - They store electrical energy in the form of hydrogen obtained from the electrolysis of water; - They co-generate electricity and heat in the fuel cell mode (the fuel is primarily stored hydrogen but can also be biomethane or natural gas). These smart energy hubs, based on a modular design adapted to cover a wide spectrum of power range, ensure or reinforce energy autonomy and flexibility in buildings, eco-districts, up to industrial sites and local energy grids connections powered by intermittent renewable energies. They allow both (i) storing excess energy generated by solar panels for several days or weeks, and (ii) covering electricity and heating needs, while adapting to the arbitration rules set by users. Sylfen implements reversible Solid Oxide Fuel Cell (SOFC) technology that has been developed at CEA for over ten years. The successful implementation of a CEA pilot project in 2014 was a worldwide first. For owners or managers of buildings, the advantages of the solutions proposed by Sylfen include: - the reduction and control of energy costs, particularly in areas where electricity rates show strong daily and seasonal fluctuation or where there is a high risk of increase; - the securing of electricity supply in areas where the electrical network is insufficient – there are many of these, even in developed countries; - the adoption of an energy profile in compliance with future standards, with less risk of seeing building value depreciate over the long therm; - a positive image, especially for emblematic buildings, both for private players who communicate on social and environmental responsibility and for public players who highlight sustainable development.
