pstrongWho we are /strong /ppH2D 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. /ppOur 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. /ppstrongThe context you will work in /strong /ppYou 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, H2D Energy leads the development of the control algorithms for the operational management of the system: you will be at the center of this activity. /ppstrongWhat you will do /strong /pp• Develop the process design of the hydrogen chain of our product: electrolysis, gas conditioning (drying, purification), compression, storage, reconversion, and the associated thermal management.



/pp• Size the hybrid storage system as a whole and design its electrical architecture: photovoltaic field, battery bank, electrolyzer and reconversion unit, power conversion and protections, power flows between the sections. /pp• Draw up and maintain the technical basis of the system: mass and energy balances, PIDs, equipment sizing, operating and safety parameters, interfaces between the H₂ section, batteries and PV. /pp• Define the functional and control requirements of the plant (operating modes, priorities, interlocks, safety-relevant shutdown logic) as the technical input for our algorithm development. /pp• Test and validate the control logic on the system#39;s digital twin and take care of its calibration. /pp• Support the safety analysis of the product: hazardous-area considerations, HAZOP participation, review of gas detection and ventilation concepts. /pp• Specify components and evaluate suppliers from a technical standpoint: requirement lists, datasheet review, technical clarification with manufacturers. /pp• Accompany commissioning and the test campaign on the Sardinian demonstrator: test protocols, measurement evaluation, troubleshooting, feedback into the product design. /ppbr / /ppstrongWhat we are looking for /strong /pp• Degree in Energy, Chemical, Mechanical or Electrical Engineering or related fields (Master#39;s degree preferred); talented new graduates are also warmly considered. /pp• Process design skills applied to energy systems: mass and energy balances, PIDs, equipment sizing, operating and safety parameters.



/pp• Foundations in electrical system design: power conversion (inverters, DC/DC), protections, single-line diagrams, sizing of the DC and AC chains. /pp• Ability to size renewable energy systems (photovoltaics, battery storage, hydrogen) and to integrate them into a single plant. /pp• Modeling and simulation skills (Python and/or Matlab). /pp• A concrete interest in hydrogen, storage systems and renewables. /pp• Fluent English, spoken and written (a must). /ppbr / /ppstrongPreferred qualifications /strong /pp• Thesis or experience in electrolysis, hydrogen, power-to-X or hybrid storage systems. /pp• Experience with sizing and simulation tools for renewable plants (PVsyst, HOMER, Aspen, Simulink or equivalent). /pp• Practice with PIDs, single-line diagrams and CAD tools. /pp• Notions of process safety (ATEX, technical gases, HAZOP) and of the electrical standards applied to PV and storage plants (CEI, IEC). /pp• Optimization and control techniques (e.g. constrained optimization, MPC) and machine learning basics. /pp• 1–3 years of experience in plant engineering, energy or process roles. /pp• Knowledge of the Sardinian language. /ppbr / /ppstrongWhat we offer /strong /pp• A central role in the development of the algorithms governing a proprietary technology, covered by two patent applications, with a declared ambition of international leadership in hybrid storage. /pp• Fast growth and real responsibilities in an expanding start-up: those who join today help build tomorrow#39;s company. /pp• Hands-on training on hybrid storage, green hydrogen and control systems, working with high-profile industrial and academic partners. /pp• Place of work: Cagliari. /ppbr / /ppstrongHow to apply /strong /ppSend your CV to with the subject line "Application – Junior Process Engineer". /p
