FAQ

How does the DESERTGREENER technology differ from other solar seawater desalination plants?
The DESERTGREENER technology stands out due to its exceptionally high efficiency in utilizing solar energy. Through innovative energy recycling, an effect is achieved that acts like energy multiplication. Compared to traditional solar plants, the DESERTGREENER technology delivers at least 25 times the energy output.
Our patented innovation is a technology that processes seawater or saltwater into fresh water and produces a variety of valuable products.
Distilled Water: Due to its purity, it is primarily used in laboratories, medicine, pharmaceuticals, and battery manufacturing to create precise solutions and clean sensitive devices. It is also used in households for gentle surface cleaning and as an electrolyte in car batteries for performance optimization. Thanks to the cost-efficient production by our technology, it may also be used in the future for agricultural irrigation and drinking water purification.
Sodium (Na): Used in the chemical industry for producing various compounds and as a preservative and flavor enhancer in food.
Chloride (Cl): Commonly used in water treatment to kill bacteria and microorganisms. It is also used in the food, chemical, and pharmaceutical industries.
Magnesium (Mg): Used in metal processing, electronics manufacturing, and fireworks production. It also has medical applications as a supplement and for treating magnesium deficiency.
Calcium (Ca): An important component for bones and teeth, commonly used as a supplement. It is also used in the food, chemical, and construction industries.
Potassium (K): Used in agriculture, especially as fertilizer to improve plant growth. It is also used in the food, chemical, and medical industries.

The patent was filed in 2018.
In most countries, the patent protection lasts for 20 years, until 2038.
Humanity needs to double the water supply in the coming decades. This can only be achieved on a large scale with DESERTGREENER technology. Egypt, for example, could receive a second Nile flowing from the Mediterranean upstream, and up to 50 million square kilometers of dry zones could be supplied with water, transforming these areas. Water scarcity and deserts would become history, creating new habitats for around 11 billion people.
What is DESERTGREENER's mission?
Our mission is to transform desert areas worldwide into thriving, fertile landscapes. By using our patented technology and sustainable methods, we aim to not only regenerate the environment but also sustainably improve the lives of people in these regions. Our projects bring food security, clean water, and economic opportunities to affected areas, creating jobs, promoting education, and supporting communities in becoming self-sufficient and sustainable.
Our vision is to provide sustainable solutions to the global water crisis with innovative DESERTGREENER technology. By applying advanced methods in seawater desalination, water treatment, and efficient irrigation, we aim to create new opportunities in desert and coastal areas facing water scarcity. Through the restoration and upgrading of salt-affected soils, we enable productive agriculture and strengthen local economies. Our commitment involves collaborating with communities, research institutions, and global partners to improve water access, increase agricultural production, and sustainably enhance people’s quality of life.
The excess energy provided by DESERTGREENER enables electrolysis, which produces a variety of useful products for different industries:
Hydrogen (H₂): Produced at the cathode and used as a clean fuel or energy carrier.
Oxygen (O₂): Produced at the anode, used for industrial applications, medical purposes, or to support combustion processes.
Chlorine (Cl₂): Also produced at the anode, used in various industrial applications including disinfectants, PVC production, and other chemicals.
Sodium Hydroxide (NaOH): Also known as caustic soda, is a valuable chemical reagent used in many industrial processes, including paper production, soap manufacturing, and water treatment.
