Fuel cells for off-grid
Microgrids are localised electricity networks that typically connect to the central grid but can operate independently when needed. They are commonly deployed in residential areas with limited grid access or in commercial settings where uninterrupted power is critical.
In rural regions, renewable sources like solar and wind are often used to support microgrid power generation. However, these sources are inherently intermittent – solar power drops at night, and wind can be unpredictable. While battery banks help store surplus energy, they cannot fully offset the variability, leading many microgrids to rely on diesel generators.
Although diesel fuel is widely available, its use presents logistical challenges, noise pollution, greenhouse gas emissions, and ongoing maintenance demands. Fuel cells offer a cleaner, quieter, and more sustainable alternative. When integrated into hybrid systems alongside batteries and electrolysers, fuel cells enable self-sufficient, zero-emission power generation – making them an ideal replacement for diesel in off-grid applications.
Challenges faced in off-grid applications
- Intermittent renewables – solar and wind energy are weather-dependent and can’t guarantee continuous supply.
- Battery limitations – energy storage systems may not hold enough charge for extended outages or high-demand periods.
- Fuel logistics – diesel generators require regular fuel deliveries, which can be costly and difficult in remote areas.
- Eliminating emissions – diesel generators produce dangerous emissions whilst running, from noise to carbon monoxide. In rural areas, this can be detrimental to the surrounding ecosystem.
Our fuel cells for off-grid
Our IE-POWER™ fuel cell modules provide zero-emission, reliable off-grid power to areas that are impacted by intermittent and unreliable grid services. With micro-grids relying heavily on diesel generators and the impacts of this on the surrounding environment regarding noise and particulate pollution, our fuel cells for off-grid applications can provide a more dependable solution and eliminate harmful emissions.
In collaboration with our partners, we are able to provide package solutions, enabling you to become less reliant on the grid. From 1kW to multi-megawatt power outputs, our solutions are scalable and can be packaged into containerised systems.
Benefits of fuel cells in micro-grid applications
- Emissions-free power – fuel cells generate electricity through an electrochemical reaction, producing no harmful emissions at point of use. The only byproduct of the process is water and heat.
- Robust reliability – wide operating temperature range of -10°C to +40, with altitude of 0m to 4000m, and 10% to 90% humidity.
- Improved efficiency – fuel cells are up to 60% energy efficient, in comparison to the typical internal combustion engine, which is around 25%.
- Near silent operation – the cell itself is incredibly quiet, making fuel cells especially well-suited for use in close proximity to people.
