No more "Delivery Tax" on your cooling.

The era of relying on high-margin gas suppliers and complex logistics is over.

Power plants are hitting a critical inflection point where the volatility of delivered hydrogen threatens both operational uptime and the bottom line.

By transitioning to on-site generation, you convert a volatile operational expense into a predictable, high-performance asset. It is time to stop managing a supply chain and start mastering your own utility.

Based on U.S. DOE Hydrogen Delivery Roadmap and NREL H2A Electrolysis Model, 2020–2023.

The future of generator cooling isn’t delivered.

It’s made on-site.

Our H-Series on-site hydrogen generators are built for generator cooling applications.

Eliminate supply chain volatility: Stop being at the mercy of driver shortages, fuel surcharges, and regional gas outages.

Slash operational expenditure (OPEX): On-site generation eliminates the hidden costs of cylinder rentals, delivery fees, and the labor required to manage high-pressure storage.

Recover “invisible” losses: Stop venting expensive gas. Precise, on-demand generation means you only produce what you consume, optimizing your generator’s efficiency without the waste.

De-risk your infrastructure: Transitioning to on-site generation removes the safety risks associated with frequent high-pressure hydrogen deliveries and massive bulk storage footprints.

Proven technology. Trusted partner.

With almost a century of hydrogen expertise, Nel has supported critical applications across energy, defence, and industry – including nuclear submarines and utility-scale power stations. Our systems are trusted where uptime, reliability, and safety are non-negotiable.

On-site hydrogen generation has already helped power plants eliminate the risks of hydrogen deliveries, reduce costs, and ensure uninterrupted generator cooling. Worldwide, operators are switching to on-site H₂ with measurable results.

New York Power Authority

NYPA completed a 2023–24 replacement of its Nel H-Series electrolyser, ensuring continued on-site hydrogen availability with upgraded reliability and maintainability.

American Electric Power

At AEP’s Clinch River plant in Virginia, on-site PEM electrolysis from Nel cuts out regular hydrogen deliveries and supports uptime.

Consumers Energy

Zeeland’s on-site Nel H-Series cut delivered-hydrogen cost per unit by ~87% versus cylinders, illustrating the cost and uptime benefits of on-site generation.
