Solar-powered water purification and desalination technology for sustainable fresh water

About Desolenator

Desolenator is a clean technology company that develops solar-powered water purification and desalination systems. Its technology aims to produce fresh water from seawater or brackish water using solar energy, reducing the reliance on fossil fuels that makes conventional desalination costly and carbon-intensive. The company has operations in the UAE, one of the world's largest users of desalinated water.

Most fresh water in the Gulf comes from desalination plants, which remove salt from seawater. These plants typically consume large amounts of electricity or heat, often generated from fossil fuels, and many produce concentrated brine that is discharged back into the sea.

Desolenator's approach uses solar energy to power a thermal purification process. By capturing heat and electricity from the sun, its systems can treat water with a much lower carbon footprint. The company has emphasised designs that minimise waste and can recover valuable by-products from the brine, supporting a more circular approach to water treatment.

The technology is designed for a range of uses, from supplying water to communities and farms to industrial applications that need purified water. Modular systems can be deployed where they are needed, rather than relying only on large centralised plants and long pipelines.

Agriculture is a significant potential market, since farming uses a large share of water in the region. Affordable, low-carbon fresh water could support local food production and food security.

The company has worked on projects and partnerships in the Middle East and other water-stressed regions, and it has received recognition in climate and water innovation programmes.

Water scarcity is one of the most serious long-term challenges in the Gulf, and climate change is expected to increase pressure on water supplies globally. The UAE has invested in research and innovation to find more sustainable ways to produce water.

Combining renewable energy and water treatment addresses two national priorities at once, clean energy and water security.

Desolenator's solar-driven approach to fresh water makes it one of the international cleantech companies with a strong UAE focus, and Startups UAE lists it among the country's water technology companies.
