Who we are
H2D Energy is an innovative start-up headquartered in Cagliari and a pioneer in hybrid energy storage. The historical limitation of renewables is intermittency: we overcome it by integrating batteries, green hydrogen and intelligent control algorithms to turn a discontinuous production into clean, continuous and dispatchable energy, 24 hours a day, 365 days a year.
Our proprietary technology, HyVault, covered by two patent applications, stores the surplus generated by renewable sources and delivers it back whenever needed — hours, days or entire seasons later: batteries cover the short term, hydrogen preserves energy over the long term without losses, and control algorithms orchestrate the whole system moment by moment. It is a scalable platform — from the few kWh of a home up to industrial and grid scale — already operating in the field, and now at the core of an industrial Proof of Concept for the decarbonization of a 350 MW thermoelectric power plant in Brazil.
The context you will work in
You will join our technical team at a time of strong acceleration: in Sardinia,
alongside leading industrial and academic partners, we are building a real-world demonstrator of our technology — a photovoltaic plant of over 100 kWp integrated with battery storage systems, an electrolyzer for green hydrogen production and electric vehicle charging infrastructure — governed by a digital twin, control algorithms and artificial intelligence. In this journey, electrical flows are the nervous system of the technology: your role will be to design and oversee them.
What you will do
The scope of the project is the construction of a hybrid battery and hydrogen energy storage system. Your responsibility is its entire electrical design: every connection inside the system, every connection between the system and the outside world, and the selection of the components that make both work.
