Point of departure

For over 20 years, Much More Water A/S has been providing water purification systems to emergency services, NGO organizations, military and defense units across more than 35 countries worldwide. The BlueBox water purification systems from Much More Water A/S can yield up to 10,000 liters per hour per unit, and they have undergone rigorous field testing by esteemed organizations such as UNICEF, the United Nations, WHO, the Red Cross, the British Army, the Norwegian Armed Forces, the Danish Emergency Management Services and the Swedish Defense. The Vision of Much More Water A/S is as simple as important: A world population with access to clean, safe and drinkable water – anytime and anywhere.


The BlueBox water purification system, which is often used in remote and off-grid areas to ensure the availability of safe drinking water, depends on the availability of reliable power sources. In the past, the water purification system relied on either diesel generators or solar power in off-grid scenarios. To ensure a completely reliable power source for the system, an environmentally friendly solution was sought that could seamlessly take full control of the power supply or work in hybrid mode with solar energy.

“Incorporating the EFOY Pro Fuel Cell into our PowerBox enables us to tap into fresh customer segments.”

Incorporating the EFOY Pro Fuel Cell into our PowerBox enables us to tap into fresh customer segments and reach end-users with an even more dependable and environmentally friendly off-grid power solution for operating our water purification systems. This innovative application presents the market with a viable substitute for grid reliance and the high fuel consumption of conventional generators. Moreover, we have the potential to enhance efficiency by integrating solar panels onto the units, thus boosting their capacity even more.
