Portable fuel cells offer the benefit of long duration, clean electric power generation in various situations where other power sources are unavailable or unreliable.

Fuel cells in these situations are usually lighter and easier to handle and offer longer working times than batteries. As they are quiet and produce no emissions they offer advantages over diesel generators, particularly in enclosed spaces or environmentally sensitive areas. At the low loads required by modern electrical equipment fuel cells are often cheaper and more reliable than small diesel or petrol gensets.

Hybridisation of a variety of power generating sources allows for maximum system flexibility, these sources include mains supply, batteries, fuel cells, solar panels and wind turbines.

We can design and build complete off-grid power systems and backup systems for your site to help you reduce operating cost, improve reliability and contribute to environmental and carbon reduction targets.

We can also also a service to monitor and survey your site and help you develop an energy plan and build the business case for introduction of innovative technologies. Our remote monitoring service will give you full visibility of your energy use and enable reporting of energy, cost and carbon savings.

With the introduction of lightweight hydrogen storage, such as the new range of Genie cylinders from BOC/Linde, power generation with zero harmful emissions has never been so easy.

Hymera - Olympic Park

The BOC Hymera™ unit is a robust unit for providing clean power at construction sites. Arcola Energy used the Hymera to power path lighting during construction at the Olympic park. 

The Hymera DC is particularly suitable for environmental monitoring applications where long unattended runtimes are required in off‐grid locations. Severn Trent Water installed 18  Hymeras along the length of the Elan Valley pipeline between Powys, Wales and the Midlands. The monitoring equipment runs for up to 2 months between replacements of cylinders, which in these remote locations reduces operating costs considerably compared with the frequent visits required by alternative solutions.

Hymera DC's inbuilt battery‐charge circuitry allows hybridisation with a battery for efficient use with low‐loads, whereby the fuel cell typically runs for 12‐18 hours per week to recharge the battery which in turn supplies power to the connected device. This improves efficiency by reducing balance‐of‐plant load while the Hymera is in low power 'sleep' mode. The Hymera includes automatic cold‐start or sub‐zero capability allowing year‐round operation in temperate climates.

Combining the system with photovoltaic panels reduces hydrogen consumption, which in turn lowers operating expense, whilst retaining the security of available power in case of extended periods when available solar power is limited (winter/extended periods of bad weather). Morgan Sindall have installed a Hymera/battery/photovoltaic system to power a noise monitor at the major Crossrail construction site in East London, where it has supplied constant power throughout the rebuilding of Pudding Mill Lane station


Lighting tower

TCP are leading producers of lighting towers for construction sites. Arcola Energy integrated a Hymera and hydrogen supply into the TCP Ecolite range of task and security lighting systems.

With no internal combustion engine or harmful emissions, Ecolite‐H2 can be used in a wide range of locations including under bridges or in tunnels. This makes Ecolite‐H2 suitable for  locations where traditional lighting towers cannot be used. Ecolite‐H2 is also ideal for environmentally sensitive areas where there must be zero risk of contamination such as near reservoirs and rivers.
