Hybrid power
Reliable continuous power with additional capacity for short-term peaks
Some operations have a relatively stable power demand, combined with short periods in which significantly more power is required. Designing the complete energy system around these occasional peaks can result in unnecessary capacity and cost. Our Hybrid power system reduces costs for these operations.
We’ll get in touch to understand your needs and assess whether one of our solutions could be the right fit.
Continuous performance with flexible peak capacity
Designed around your power profile, the ONENSYS Hybrid Power solution combines hydrogen and battery technology to deliver reliable continuous power while efficiently supporting periods of increased demand.
The ONENSYS hybrid power solution combines the H2-Powergen with a battery system supplied through our technology partners. The H2-Powergen provides the continuous power required for day-to-day operations, while the battery supports short-duration peak loads.
How the hybrid system works
When demand is lower, available power from the H2-Powergen is used to recharge the battery. When demand rises, the battery releases this stored energy to provide additional power. This makes the setup particularly suitable for applications such as fast-charging electric construction equipment, vehicles or machinery.
The H2-Powergen supplies the stable, ongoing power demand of the operation.
During periods of lower demand, the H2-Powergen uses its available capacity to charge the battery.
When power demand temporarily increases, the battery provides additional capacity without requiring the H2-Powergen to be sized for the full peak load.
Key benefits
- Continuous zero-emission onsite power
- Additional capacity for short-duration peak loads
- Efficient use of the H2-Powergen’s available capacity
- Reduced need to oversize the hydrogen power system
- Smaller battery capacity required
- Battery technology selected with specialised partners

Designed around your power profile
ONENSYS assesses your continuous power demand, peak loads, operating hours and charging requirements. Based on this profile, we configure the H2-Powergen capacity and coordinate the appropriate battery system with our partners. Depending on the selected battery system and required peak power, the hybrid power system can be configured to deliver peak power of 1 MW or more.
We manage the complete onsite power setup, including system configuration, deployment, operational support and facilitation of hydrogen supply. This allows contractors and project teams to focus on their work while we ensure reliable zero-emission power onsite.

Frequently asked questions
The grid connection for my project is delayed — can ONENSYS provide power in the meantime?
Yes — this is one of the most common situations we solve. We assess your power demand and configure an onsite energy system that delivers the capacity you need while the grid connection is unavailable, insufficient or not yet ready, so your project can start on time.
Do I need a fixed grid connection to use an ONENSYS system?
No. Our systems operate off-grid and grid-connected. For temporary and mobile projects we provide reliable power without depending on fixed infrastructure, and the setup can move with your project.
My site must meet zero-emission or Natura 2000 requirements. Is that possible without stopping work?
Yes. We configure zero-emission onsite power that supports compliance with Natura 2000 restrictions, SEB requirements and procurement criteria — without bringing your operation to a halt. Where conventional generators are no longer allowed, this is exactly the gap we fill.
I'm not sure which challenge applies to my project. How do I find out?
Many projects face several overlapping constraints: limited grid capacity, emission requirements and tight timelines. Contact us to assess your onsite power challenge. We evaluate your energy and power demand, grid situation and emission requirements, then explore the right power setup for your site.
Can ONENSYS guarantee system performance?
Depending on the project and operating requirements, ONENSYS can agree contracted performance levels covering areas such as power availability, monitoring, maintenance and service response. The exact commitments and conditions are defined in the project agreement.
