Dutch hydrogen technology company zepp.solutions has introduced a new line of zero-emission hydrogen-powered generator sets designed to replace conventional diesel generators in off-grid and high-demand power applications. The zepp.generator series delivers up to 600 kW continuous and 1 MW peak power output, offering a scalable and transportable clean energy alternative for industrial and maritime operations.
The systems are designed as stand-alone, ready-to-use units, with all necessary components housed within standard 10- or 20-foot ISO containers. Each generator produces electricity from hydrogen without emitting CO₂, NOₓ, or particulates, in line with tightening global emission standards.
Real-World Deployment and Use Case
The zepp.generator has already entered operational service. A 10-foot unit is currently supplying power to Van den Herik-Sliedrecht’s Prins ZEs, the Netherlands’ first fully electric wire crane vessel. The generator charges the ship’s 2 MWh battery system overnight, enabling a full day of emission-free dredging operations.
“These containerised solutions make large-scale zero-emission power accessible anywhere,” said Jonas Brendelberger, Chief Technology Officer at zepp.solutions. “With these systems, we’ve made hydrogen fuel cell power as easy to deploy as diesel, but without the emissions or noise.”
Performance and Efficiency
Based on the company’s proven X150 fuel cell platform, which already powers hydrogen trucks and vessels across Europe, the zepp.generator achieves efficiency levels of up to 62%. The systems provide a cost per kWh comparable to diesel while eliminating greenhouse gas and pollutant emissions.
An integrated lithium-ion battery enhances performance by enabling rapid load response, energy buffering, and black-start functionality — making the units suitable for both continuous and intermittent power demands.
Applications and Deployment
The generator’s modular, containerised design enables deployment across multiple sectors, including:
- Construction and infrastructure projects requiring off-grid power
- Maritime shore power for vessels in port
- EV fast-charging stations in remote or grid-limited areas
- Temporary or backup power in grid-congested regions
Hydrogen can be supplied via tube trailers, MEGCs, or cylinder bundles, supporting energy capacities from hundreds of kWh up to tens of MWh.
Technical Specifications
| Model | Continuous Power | Peak Power | Battery Capacity | Container Size |
| G240 | 150 kW | 240 kW | 80 kWh | 10 ft |
| G500 | 300 kW | 500 kW | 150 kWh | 10 ft |
| G750 | 450 kW | 750 kW | 250 kWh | 20 ft |
| G1000 | 600 kW | 1 MW | 300 kWh | 20 ft |
By matching diesel’s performance with zero emissions, the zepp.generator offers an immediate path to decarbonisation for energy-intensive operations without compromising reliability or mobility.
