Batteries are efficient for daily shifting (charging at noon, discharging at night), but they suffer from self-discharge and economic waste over weeks or months. For microgrids that need to store summer solar or wind energy for winter use, hydrogen has near-zero self-discharge. You can produce hydrogen in summer when renewable energy is abundant and use it in winter for power, without the 30–40% energy loss you would incur from letting a battery bank sit for months.
You have two options. Option1: Use our hydrogen battery. It is a modular system with a minimum power of 50 kW. Once connected to electricity, it stores energy in the form of hydrogen — no additional hydrogen supply is required. Charging and discharging are integrated into a single unit. Option 2: we can integrate an on-site electrolyzer powered by your renewable assets (solar/wind/hydro) to make your own green hydrogen.
Our electrolyzers use PEM (proton exchange membrane) technology, which is highly dynamic. Unlike old alkaline systems that take minutes to ramp, our electrolyzers can go from 0% to 100% load in under 5 seconds. This allows the microgrid controller to dump excess solar or wind power directly into hydrogen production instantly, acting as a "shock absorber" for the grid. When renewable output drops, the fuel cell seamlessly takes over.
Many remote microgrids rely on diesel or heavy fuel oil delivered by ship or truck, which is expensive and subject to supply disruptions. Hydrogen allows you to utilize local renewable resources (solar, wind, hydro) to create a "fuel factory" on-site. This replaces fossil fuel logistics with local energy independence, stabilizes power prices for decades, and drastically reduces noise and air pollution in sensitive environments.
Yes. This is a key advantage of hydrogen in microgrids. The fuel cell generates electricity, but the electrochemical reaction also produces high-quality waste heat (50–70°C). We integrate heat recovery systems to warm buildings, greenhouses, process water, or district heating loops. This combined heat and power (CHP) approach boosts your total system efficiency to nearly 90%, making hydrogen much more attractive when a thermal load exists.
Highly modular. We start with containerized solutions (e.g., 100kW power / 400kWh storage) and scale by adding parallel fuel cells and hydrogen storage racks. Because hydrogen storage scales via tanks (not electrochemical cells), it is significantly cheaper to add "duration" (hours or days of backup) to a hydrogen system than to a battery system. You can size your power for daily peaks and your storage for weekly or seasonal needs independently, optimizing your capital expenditure.
