Powering the future, beyond the grid
Wattmelon designs and delivers clean, off-grid hydrogen-electric charging solutions that are built for real-world use. Our flagship system offers reliable, flexible and rapid EV charging where traditional infrastructure falls short.
We started Wattmelon to remove the biggest blocker to EV adoption: dependable power where it’s needed most. Our team blends expertise in hydrogen systems, power electronics and charging infrastructure to deliver stations that are clean, robust and effortless to operate.
Whether it’s remote locations, temporary installations or sites with poor grid connectivity, Wattmelon provides a smarter, greener alternative – with zero reliance on mains electricity.
We convert hydrogen into electricity on site to deliver fast, dependable charging for fleets, public destinations, logistics hubs and remote locations.
The H2EV480 isn’t just another charging point – it is a fully off-grid, low-emission power station that makes EV charging possible almost anywhere.
As the world races toward net zero, access to energy remains one of the biggest challenges in deploying clean transport infrastructure. We believe the solution lies in hybrid technologies – ones that combine mobility, low emissions, and simplicity.
The grid isn’t always where you need it and even when it is, capacity, cost and timelines can slow projects down.
Our stations bypass grid constraints, accelerate roll-outs and keep operating costs predictable, while delivering genuinely green energy.
Our off grid hydrogen fuel cell + fast-charging technology is designed to provide convenience, reliable and super fast charging for electric vehicles. Our electro – hydrogen units offer a unique combination of flexibility, speed and sustainability, making them the perfect choice for EV owners wherever grid connection is challenging.
Certified green hydrogen is delivered to site and stored safely.
Our hydrogen-electric unit converts hydrogen to electricity with high efficiency and low acoustic footprint.
Smart controls balance generation, on-board storage and charger output to maximise uptime and protect assets.
Configured with AC and/or DC fast chargers, access-controlled via app, RFID or contactless payment.
To accelerate the transition to clean energy by redefining how, where and when power can be delivered.
To design and deliver off-grid, low-emission charging solutions that are practical, scalable, and future-ready.
• Fleet depots and logistics yards needing rapid, scalable rollout
• Retail parks, destinations and forecourts seeking revenue-ready fast charging
