450 days ago, in July 2024, we launched the next phase of DesertGreener with an intensive workshop at the Fraunhofer Institute. Back then, the foundation was laid to take our technology to a new dimension – with a clear goal: to make sustainable fresh water from seawater available around the clock, everywhere. Today, we take stock: What have we achieved during this time, and where are we headed?
From the very beginning, it was clear: True 24/7 operation is only possible with the intelligent combination of thermal and electrical evaporation. Using solar energy during the day, stored heat at night – this combination forms the basis for continuous fresh water production. This is precisely what we have been working on with full energy over the past few months. Our systems have grown from 800 to 2,400 square meters of mirror surface. Thousands of hours of technical work were spent developing plans, calculating simulations, creating parts lists, analyzing weak points, and finding solutions – often late into the night. Together with Fraunhofer, we discussed technical issues, revised concepts, and gradually refined our prototypes. All of these developments were integrated into Prototype 3, which forms the technical starting point for the thermodynamic simulation that has been running at Fraunhofer since the beginning of August.
Prototype 2.0 is currently being expanded into 2.1 and will form the foundation for our large-scale systems in the future. This semi-automated prototype will not only serve as the basis for extensive test series, but will also be closely integrated with our simulations to enable immediate evaluation of simulation results. At the same time, we are expanding Prototype 1 so that we can also serve smaller, customized applications – an important step toward broader marketability.
Our thermal simulation at Fraunhofer is nearing completion and will enable us to plan new systems even more precisely and efficiently in the future. In the fourth quarter of 2025, we aim to evaporate and recondense the first liters of water with our first showcase system, the expanded and optimized Prototype 2.1 – a symbolic but crucial proof of concept.
But technology alone is not enough. That’s why we’ve been working intensively on strategic partnerships in parallel. We’ve established contacts with plant manufacturers, supply chains, and production partners to ensure that our vision can be implemented industrially, and we’ve strengthened our team in key positions. We’re in close contact with research centers and political decision-makers in Gran Canaria, Cyprus, and other regions regarding research collaborations and initial pilot plants. These should not only provide valuable test results but also form the foundation for subsequent series production.
We are also negotiating with leading political and economic decision-makers in Egypt, South Africa, Chile, Paraguay, and other countries about selling purchase options for the future supply of our water, establishing local distribution partnerships, and potential funding for the construction of our plants and the necessary pipeline infrastructure. The response has been extremely positive: There’s great interest in taking the next steps together – a clear signal that DesertGreener is in tune with the times.
450 days after the workshop, it’s clear: We’ve not only made significant technological progress, but we’ve also laid the foundation for the next step strategically, in terms of personnel, and organization. But even more importantly, we continue to work with passion and conviction, with the firm goal of making a real contribution to solving one of the greatest global challenges – clean water for all, sustainably and emission-free.
