Silal
Abu Dhabi
The UAE’s desert landscape makes food security and local production a challenge due to lack of abundant renewable freshwater and fertile soil. This has resulted in the UAE importing over 85% of its food. Desolenator, along with Silal (the UAE’s national AgriTech company), established a world-first, circular, solar desalination plant that desalinates brackish desert groundwater, and custom re-mineralises it for crop irrigation in controlled environment agriculture, as well as providing sustainable cooling for greenhouses. This is fully powered by a combination of Desolenator’s patented solar PV-thermal panels and conventional PV panels. The demo plant is located at Silal’s Innovation Oasis R&D Center in Al Ain (Emirate of Abu Dhabi), UAE.
This demonstrator project proved that our patented thermal desalination system can reliably operate in the extreme conditions of the desert. It produced 136,875 kWh of clean solar energy annually, enabling the generation of 9.1 million litres of ultrapure water per year. Compared to conventional reverse osmosis, it avoided 2,737 kg of chemical use annually, while delivering emissions savings of 76,790 kg CO₂e per year versus the UAE grid. In addition, the project supported the creation of approximately 20 jobs across its lifecycle. With the technology successfully validated, we are now exploring options for commercial scale-up.
Today industrial desalination uses 0.4% of the global annual electricity and is on track to be responsible for 5% of global carbon emissions by 2040. Addressing this challenge, Desolenator uses no membranes, chemicals or polluting diesel, unlike traditional technologies. Instead, the patented technology uses the planets most abundant resource – the sun. By harvesting thermal and electrical energy from an integrated PVT panel, Desolenator produces high-quality water, monitored via a control panel. This solution eliminates external energy requirements, aiming to provide drinking water for all at low cost and with low environmental impact.
