Flemish technology company Tiger Power and De Watergroep have signed a declaration of intent to work together on the development of an energy-efficient drinking water production unit to ease some of the pressures brought on by climate change.

The mobile drinking water system, is built in a converted container and runs on solar power. Easily deployable and installed, the same approach is already being used by the Flemish scale-up Tiger Power in its renewable energy solutions.

Hydrogen as energy carrier

Both parties are looking to build experience in the generation of renewable energy and the decentralised production of drinking water. This should lead to a growing insight into the role of water and hydrogen gas as secondary energy carrier.

Flemish relevance

There is a strong belief that the insights will also be relevant to Flanders in the long term.  Storage plays a key role in the transition to a renewable energy system. Hydrogen can be used flexibly to balance fluctuations in renewable energy, thereby guaranteeing grid stability.

Remote monitoring

Finally, both companies also want to gain experience in remote monitoring of drinking water quality. Lab-on-a-chip technology can be an important lever to improve the worldwide quality of drinking water, which in turn benefits public health.

Flying start

Tiger Power and De Watergroep will immediately start work on some concrete projects:

  • Kyenjojo - Uganda:
    Tiger Power is currently installing local energy production units with mini-grid in three Ugandan villages. These projects will be expanded with the drinking water production unit.
  • Galibi – Surinam:
    De Watergroep has been active in Surinam for some years now and has extended the drinking water supply in the coastal municipality of Galibi. The existing energy infrastructure will be optimised based on Tiger Power's product portfolio.
  • Optimisation of Storager water consumption:
    Tiger Power sees a number of opportunities to further optimise its Storager (hydrogen-based energy storage container). De Watergroep has the relevant knowledge and experience to contribute to this.

Hans Goossens, Director General of De Watergroep commented: "As a public water company, we also attach great importance to social commitment. For instance, in the past few years we have been using our knowledge and expertise for projects on sustainable drinking water supply in developing countries."

Chris Prengels, CEO of Tiger Power said: “When constructing stand-alone power plants in developing countries, we are often asked to also supply (drinking) water in addition to renewable energy. The collaboration with De Watergroep is an important step in our ambition to achieve a lasting socio-economic impact in developing countries. Capitalising on the nexus of renewable energy – drinking water is crucial to this end.”
