Hydrovert Energy has developed hydrogen fuel cell-based stationary power generators with capacities ranging from 5 kVA to 50 kVA for long-term backup power in commercial and industrial applications. The systems use hydrogen as the sole fuel input, regardless of whether the hydrogen is produced via fossil fuel-based processes, renewable electrolysis or nuclear energy.
Pune based startup Hydrovert energy has developed hydrogen fuel cell-based stationary power generators with capacities ranging from 5 kVA to 50 kVA for long-term backup power in commercial and industrial applications.
The company’s founder, Supriya Patwardhan, told pv magazine that the systems use hydrogen as the sole fuel input, regardless of whether it is produced via fossil fuels, renewable electrolysis or nuclear energy routes.
The generators combine proton exchange membrane (PEM) fuel cells with battery storage in a hybrid architecture designed to improve fuel cell efficiency and durability while reducing capital costs.
Hydrovert produces key components in-house, including fuel cells, battery packs, power electronics, fuel cell controllers and electronic control units (ECUs), with the components being 95% indigenous, Patwardhan said.
She said the generator sets produce zero emissions and operate without noise pollution, positioning them as an alternative to diesel generators. The systems also generate warm exhaust air of approximately 45°C, which can be used to heat indoor spaces in colder climates.
The units include integrated hydrogen leak detection sensors, remote monitoring capabilities and multiple protection systems including temperature, overcurrent and short-circuit protection. Users can remotely monitor hydrogen levels, battery status and energy generation.
Depending on application requirements, the systems can supply 230 V AC single phase, 415 V AC three phase or 12 V/36 V/48 V DC.
According to the company, operating costs are lower than those of diesel and natural gas generators, although capital expenditures remain approximately six times higher than comparable diesel generators due to the early stage of the technology. Hydrovert expects costs to decrease as a result of increased scale and automation of production.
Indian utility NTPC commissioned the company’s first commercial deployment at a facility in Greater Noida in April 2026.
