eProInn

What eProInn does

eProInn s.r.l. (Energy and Propulsion Innovation) is an Italian research-oriented SME headquartered in Fisciano (Campania), founded in 2014 as a spin-off of the University of Salerno by professors and researchers from the eProLab Energy and Propulsion Laboratory. It develops green-economy technologies for energy and propulsion across terrestrial and aeronautical sectors. Its portfolio spans three core technology lines: HySolarKit, a patented kit to retrofit conventional cars into solar hybrid vehicles and avoid premature scrapping; PRD (Predictive Regeneration in Downhill), an algorithmic device that forecasts descents without a navigator to maximize regenerative energy recovery in HEVs and BEVs; and PPVM, a software platform offering 48-hour photovoltaic production and solar insolation forecasts that optimize storage and programmable loads in grid-connected PV systems. Longer-horizon research covers UW-CAES underwater compressed air energy storage and the DIVAX-2 vertical-takeoff hybrid aircraft prototype.

The firm earns revenue primarily through publicly funded R&D projects rather than direct commercial sales, with streams tied to European projects (LIFE-SAVE), regional grants (DIVAX-2 from Regione Campania), bilateral international projects (VHU Vehicle Hybridization in Uzbekistan), and licensing/royalty arrangements. Commercialization of HySolarKit is channeled through the participated startup SunMotive, while technology visibility is built through membership in the Campania Aerospace District (DAC) and Kyoto Club, plus exposure events such as EXPO Dubai 2022 with InElectric. End-user segments addressed include private vehicle owners seeking hybrid conversion without new-vehicle purchase, photovoltaic/storage operators needing load and procurement optimization, and—prospectively—urban air mobility platform developers.

The leadership base consists of four shareholders led by Founder Gianfranco Rizzo (Professor Emeritus of Mechanical Engineering at the University of Salerno and majority shareholder), with minority shareholders Alfredo Tafuri (former FIAT Torino executive), Marco Farci (international politics expert), and Marco Mandolesi (entrepreneur, CEO of Mamanero Srl). Headcount is small at 1-10 employees, including dedicated social media and webmaster roles, and the firm holds no external institutional investor or parent entity, operating as an independent university spin-off that registered as an Italian SME (PMI) in 2019.

• PPVM

Products and services

• HySolarKit A conversion kit that transforms traditional cars into solar hybrid vehicles, preventing premature scrapping of vehicles still in good condition while delivering energy and environmental benefits from a life cycle assessment perspective. Developed for automotive owners and industrial vehicle conversion applications.
• PRD (Predictive Regeneration in Downhill) A device integrated into hybrid vehicles that significantly increases energy recovery during downhill phases by predicting upcoming descents without requiring a navigator, reducing fuel consumption and emissions. Also applicable to electric vehicles to improve remaining range estimation and reduce charging anxiety.
• PPVM (Photovoltaic Management Software) Software for optimal management of a photovoltaic system equipped with a storage system and connected to fixed and programmable electrical loads. Provides 48-hour forecasts of solar insolation and photovoltaic power production based on weather forecasts, enabling approximately 20% reduction in energy procurement costs from the grid.
• VHU (Vehicle Hybridization in Uzbekistan) International research and conversion service project for converting traditional cars to hybrid vehicles in Uzbekistan, developed in partnership with subsidiary startup SunMotive.
• DIVAX-2 (Disruptive VHDT Autoplane) R&D project service for the development of a prototype flying car with hybrid propulsion featuring vertical takeoff, delivered as part of the Campania Aerospace District Urban Air Mobility initiative.
