Despite critical water stress, the nation is working towards food independence as part of its National Food Security Strategy. Making agriculture sustainable will require innovative solutions, especially as traditional desalination relies heavily on fossil fuels and produces toxic brine.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Technology developer Desolenator has developed the world\u2019s first fully circular solar thermal desalination system. Joining forces with agri-food tech company Silal, they put it to the test in the greenhouses of the UAE desert.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The aim was to turn saline groundwater into safe water for irrigation and cooling for greenhouses. The trial at the Al Ain solar plant showed off-grid desalination can reliably support desert agriculture without brine disposal challenges.<\/span><\/p>\n<h4><b>Benef\u00edcios da abordagem\/inova\u00e7\u00e3o<\/b><span style=\"font-weight: 400;\">\u00a0<\/span><\/h4>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Circular resource model<\/b><span style=\"font-weight: 400;\">: The system converts brine into useful salts, achieving zero liquid discharge and eliminating toxic waste associated with traditional desalination.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Energy independence<\/b><span style=\"font-weight: 400;\">: Utilizing proprietary PV-T panels, the system operates off-grid with thermal storage, decoupling water production from fossil fuel reliance and price volatility.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Agricultural resilience<\/b><span style=\"font-weight: 400;\">: Custom remineralisation of water optimises crop yield, while integrated cooling reduces greenhouse water consumption by significant margins.<\/span><\/li>\n<\/ul>\n<h4><b>Specialist Services Involved<\/b><\/h4>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Trial design support<\/b><span style=\"font-weight: 400;\">: We evaluate technology trial plans based on users\u2019 innovation frames.\u00a0 The Trial Reservoir specifically addresses key questions that the trial must answer.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Trial validation<\/b><span style=\"font-weight: 400;\">: We receive and assess the trial end report from the technology vendor.
