The challenge
Our client was organizing a large-scale corporate event hosting more than 300 attendees, with strong sustainability commitments and a clear objective: deliver a decarbonized energy solution aligned with their environmental strategy.
However, the available grid connection on site was insufficient to meet the total power demand required for the event.
Under typical circumstances, additional capacity would be supplied using diesel generators. In this case, that option was not acceptable. The organizer required:
- Zero local emissions
- Reduced carbon footprint
- Silent operation to preserve the event environment
- The use of green hydrogen as a clean energy source
- Strict adherence to safety management standards
The challenge was not simply to provide additional power, but to install a reliable, low-carbon temporary energy solution capable of supporting a high-attendance event while meeting demanding environmental and safety.
The Kinell solution
To supplement the limited grid connection and meet the event’s sustainability objectives, a hydrogen-based power architecture was installed and commissioned around the H150-ICE hybrid hydrogen genset, rated at 150 kVA / 120 kW.
Beyond generator deployment, the solution included coordinated hydrogen supply logistics and strict safety management protocols to guarantee secure handling and operational reliability.
By replacing a conventional diesel backup solution with hydrogen-based generation, the architecture delivered zero local emissions while achieving a significant reduction in overall carbon footprint. The generator operated at lower noise levels than a traditional diesel alternative, preserving the acoustic comfort expected at a high-attendance corporate event.
The result was a fully operational, low-carbon temporary energy system combining performance, environmental responsibility, and safety without compromise.
Deployment & event operation
The event took place on a private estate where the existing grid connection was sufficient to power the château (kitchen, sanitary facilities), but not the outdoor installations.
Kinell deployed the H150-ICE hydrogen generator as a dedicated external power source. Installed at a safe distance to comply with ATEX requirements and connected to the organizer’s mobile metering unit, the generator operated as a separate circuit independent of the main grid.
With a capacity of 150 kVA / 120 kW, the hydrogen generating set supplied the outdoor lighting, sound system, and refrigeration equipment throughout the evening.
This configuration ensured reliable operation of all external installations while maintaining zero local emissions.
Measured environmental impact
The environmental performance of the solution was evaluated against a conventional diesel generator setup delivering equivalent power output.
While a diesel-based solution would have generated substantially higher carbon emissions, the hydrogen-based system achieved an overall 70% reduction in carbon footprint, while producing zero local emissions during operation.
This demonstrates that hydrogen-powered temporary energy systems can significantly reduce the environmental impact of large-scale events, even when high performance and reliability are required.

As corporate sustainability commitments become more ambitious, temporary energy solutions must evolve accordingly.
This project demonstrates that hydrogen-based power generation can provide a viable, low-carbon alternative to diesel for high-demand events, while maintaining operational reliability and safety standards.
By designing and deploying integrated temporary energy architectures, Kinell enables organizations to translate environmental ambition into operational reality.
