Knowledge
Insights that help you make better energy decisions.
The energy landscape is evolving rapidly. ONENSYS Knowledge explains topics such as grid congestion, electrification, emission requirements and hydrogen, helping visitors make informed onsite power decisions.
Zero-emission construction: SEB & SPUK
The transition to zero-emission construction is accelerating. SEB requirements and SPUK SEB compensation are making clean onsite power increasingly relevant for public tenders, infrastructure projects and construction sites. The H2-Powergen provides a practical way to replace diesel power with reliable zero-emission electricity where grid capacity is unavailable or insufficient.
Practical and safe hydrogen power onsite
Deploying the H2-Powergen onsite is more practical than many expect. For typical construction site applications, deployment can generally be organised without an environmental permit when hydrogen storage remains below 5,000 kg, with only a notification required in advance. The system requires limited space, can be monitored remotely and is designed with controlled hydrogen supply, automatic shut-off and clear safety procedures.

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.
