  • Announcement came on the side-lines of Saudi Water Forum.

About the entity

ACWA Power
We are a developer, investor and operator of power generation and desalinated water plants with 49 assets in operation, construction or advance development. We employ over 3,500 people across 11 countries.

ACWA Power, a leading Saudi developer, investor, and operator of power generation, water desalination and green hydrogen plants, and Water Global Access (a R&D company, developer of a world-leading water desalination technology by hydraulic injection) announced a strategic partnership to develop further WGA’s disruptive, green water desalination technology, at the sidelines of the Saudi Water Forum.

This partnership agreement represents a key element within ACWA Power’s ambitious technology innovation roadmap that aims to deliver exceptional value to future projects and to the Kingdom of Saudi Arabia as it will involve the integration of WGA’s Hydraulic Injection Desalination (HID) into ACWA Power projects.

Thomas Altmann, EVP Innovation & New Technology of ACWA Power, said: "Seawater desalination is an energy-intensive process and ACWA Power has already pioneered a paradigm shift in the industry and significantly reduced the energy consumption to unprecedented low levels. This partnership with WGA will fast-track the next step-change in energy efficiency to pave the way towards the deployment of greener technologies through innovation. We look forward to implementing this technology—and more—in support of ACWA Power’s mission to reliably and responsibly deliver power and water at low cost."

"Our goal is to reach society by the end of this year with scalable, robust seawater desalination technology with low maintenance costs and minimal environmental impact, capable of transforming the freshwater paradigm," said Eusebi Nomen, one of WGA HID inventors.

HID is considered as an environmentally friendly option in desalination as chemical treatment of water is not required and the brine released is entirely green

This technology represents a breakthrough desalination innovation. Classified as “green” technology, HID is considered as an environmentally friendly option in desalination as chemical treatment of water is not required and the brine released is entirely green. Additionally, the HID energy consumption is substantially lower than that required by existing desalinization technologies and its thermodynamic principles have been proven in a prototype unit. Recent computational fluid dynamics (CFD) modelling has successfully confirmed that WGA’s technology allows for the desalination of 40,000-ppm seawater with a Specific Energy Consumption (SEC) of less than 1.9 kWh/m3—nearly a third lower than existing SWRO projects.

During the three-day conference and exhibition held under the Patronage of His Royal Highness Prince Faisal bin Bandar bin Abdulaziz, Governor of Riyadh, and in the presence of His Royal Highness Prince Mohammed bin Abdulrahman bin Abdulaziz, Deputy Governor of Riyadh Region, and His Excellency Eng. Abdulrahman Abdulmohsen A. AlFadley, Minister of Environment, Water and Agriculture, ACWA Power showcased its desalination portfolio within the Kingdom as a Strategic Partner of the Saudi Water Forum. The company reinforced its position as the largest private water desalination operator in the world, an industry technology innovation leader, reliably and responsibly building water resources globally, while complementing the theme of the Saudi Water Forum: ‘Water Sustainability. A Responsibility for All.’

ACWA Power currently delivers desalinated water to 24 million people worldwide with a portfolio of 16 water desalination plants out of which 50% are located in the Kingdom of Saudi Arabia & include Jubail 3A IWP, Petro-Rabigh IWP, Shuaibah IWPP and Rabigh 3 IWP, Saudi Arabia’s largest independent water project and the largest reverse osmosis desalination plant in the world.

During the Saudi Water Forum, Thomas Altmann, Executive Vice President, Innovation & New Technology at ACWA Power took part in a panel discussion titled “Integrated Carbon Capture and Utilisation (CCU) with RO Seawater Desalination” and shared insights on the utilisation of carbon dioxide in reverse osmosis plants and the resulting enhancement in relation to greener desalination. Dr. Tariq Nada, Vice President, Water & Technical Service ACWA Power, KSA also participated in a panel around “KSA Desalination Code - Transmitted Water Quality… Room for Improvement”.
