Our technology

As much power and capacity as a traditional generator, but fully sustainable and without harmful emissions. It may sound like a pipe dream, but thanks to Watermeln's innovative hydrogen generators, this is now a reality.

With battery and fuel cell technology we provide powerful peak power from the battery, while the fuel cell keeps it continuously charged. Our hydrogen bundles store up to 10 times more energy per square metre than traditional batteries, and with a quick swap in just 10 minutes, we ensure unlimited capacity.
