With a background in electrical energy engineering, Julien was first involved in smart grid works before focusing on photovoltaics. At the young company Sunchain, he is in charge of solar energy activities, alongside the management of customer projects. As digital technologies take an ever-growing place in the energy field, Julien embraces them, all the while offering applied business skills to each of Sunchain’s diverse projects. Sunchain provides blockchain-based solutions to new use cases of solar energy, such as distributed and roaming self-consumption. In particular, Sunchain's solutions efficiently manage local power exchanges between prosumers and consumers. While energy is carried by the physical public grid, a virtual private distributed network is implemented to secure and certify these flows. This service also offers prosumers the opportunity to use one’s own energy in a context of electric mobility – for instance, in order to charge an electric vehicle remotely from home.
