Indonesian technology for a cleaner energy future — turning abundant silica sand, plasma and engineering into practical hydrogen systems.
Matter becomes energy.
An abundant Indonesian material. The foundation for advanced energy technology.
Silica sand, engineered at the material level into active silicon.
Hydrogen carried in solid form — safe, economical, and practical to ship across islands.
Available where and when energy is needed.
For transportation, power generation, industry and future infrastructure.
Production, storage and conversion — engineered to work as a single value chain from Indonesian silica sand to usable clean energy.
Hydrogen production, engineered as a system.
Modular hydrogen production packages for diesel power plants, industry and demonstration projects — with capacity configurable from tens to hundreds of kilograms of hydrogen per day.
Hydrogen. In solid form.
HydroSi transforms Indonesian silica sand into active silicon — a solid hydrogen carrier that is safe to handle, economical, and practical to ship between islands.
Breaking molecules with controlled plasma.
A reactor platform that uses high-temperature plasma to break down water vapor, urea and ammonia molecules into hydrogen gas and derivative products.
HDI's technologies are not isolated products. Production, solid storage and conversion form a single chain that carries Indonesian silica all the way to usable energy.

Trace the path from raw silica to end-use energy. Every stage is a real HDI technology or application area.
From converted vehicles on Jakarta streets to gensets, kitchens and island logistics — HDI technology is built for deployment, not for the lab shelf.
HDI takes its technology into the open — city streets, public exhibitions and national hydrogen events — together with partners in Indonesia's energy ecosystem.
Together with PLN Suku Cadang and the Indonesia Fuel Cell and Hydrogen Energy Society (IFHE), HDI brought hydrogen technology to the public at Dukuh Atas, Jakarta — including a Daihatsu Terios converted to hydrogen fuel and working hydrogen stove units.
Coverage: Koran JakartaHDI joined PLN Suku Cadang in bringing clean-energy innovation to Hydrogen Day 2025, presenting its hydrogen technology to a broad public audience.
Coverage: PT PLN Suku CadangAt the Indonesia Fuel Cell and Hydrogen Energy forum, HDI and PLN SC presented a hydrogen-fueled vehicle and hydrogen cooking innovation, showcasing practical applications of Indonesian hydrogen technology.
Coverage: Warta EkonomiPT Hidro Dinamika Internasional is an Indonesian deep-tech company based in Jakarta Selatan & Bandung, Indonesia. HDI builds a hydrogen value chain from silica sand and plasma technology to real applications — vehicles, cooking, gensets and clean electricity — for Indonesia and the world.
The company is open to collaboration with industry, research institutions and international partners in hydrogen technology development and deployment projects.
