A new era of desalination is emerging, propelled by technological advancements and the urgent need for fresh water globally. The video from FT Food Revolution explores the current state and future potential of desalination technology. Despite desalination plants historically being costly and energy-intensive, innovations in solar power and new desalination methods are making the process more feasible and environmentally friendly. With around 180 facilities under construction or in the planning stages, primarily in the Middle East and North Africa, the focus is on integrating renewable energy sources to power these operations. Additionally, novel approaches like self-cooling greenhouses in Australia and wave-powered desalination units point to a diverse future for the industry. However, the challenge of reducing the environmental impact of brine disposal and the reliance on fossil fuels remains significant.
Desalination plants have historically provided only about 1% of the world’s drinking water due to high costs and energy consumption.
A 2020 study suggests that the cost of desalinated water could be significantly reduced by using solar power and battery storage systems.
The Middle East and North Africa, regions with high desalination activity, are investing in renewable energy-powered facilities.
Innovations such as self-cleaning membrane technology and nuclear or wave-powered desalination plants are under development.
Australia is experimenting with a self-cooling greenhouse that uses wind to desalinate seawater for irrigation.
The global desalination equipment market, valued at $17 billion in 2023, is expected to grow to $32 billion by 2030.
Environmental challenges, including the disposal of salt-saturated brine and reliance on fossil fuels, still need to be addressed.
