An energy solutions provider has been awarded $2.5 million (£1.9m) for desalination projects in Saudi Arabia.

Energy Recovery’s technology uses pressure energy that would otherwise be wasted to slash power consumption and help increase the lifespan of pumps used to create clean water.

This is performed with 98% efficiency and without using any electrical power.

Orders for the firm’s Pressure Exchanger technology began shipping in the second quarter of 2017, with expected completion by the third quarter of 2017.

The devices to be installed at the plants will help produce a total of up to 103,000 cubic meters of water per day.

Energy Recovery estimates the equipment will reduce the total power consumption for all projects by 14.4MW, saving a total of more than 124.4GWh of energy per year and avoiding nearly 75,000 tons of carbon dioxide emissions annually.

Energy Recovery’s President and CEO, Joel Gay, said: “We remain laser-focused on our water business and will continue to guard our position as market leader and attack new opportunities to provide our Pressure Exchanger technology to customers seeking to optimise plant savings and operations.”

In the UK, Yorkshire Water has appointed energy supplier ENGIE to help reduce its annual electricity costs, which totalled £53 million last year.
