What does it take for a country to meet the bold commitment of becoming a net-zero carbon emissions society by 2045? Pioneering new possibilities, cutting-edge innovations, and the right sustainably-focused partners to make it happen.
That’s the current scene in the United Kingdom, where a groundbreaking energy hub project will use state-of-the-art technology to advance wastewater cleaning solutions, while accelerating decarbonization and aiding in the successful fulfillment of time-targeted emissions goals.
Scottish Water Horizons has teamed up with Trane® in conjunction with Scotland’s Low Carbon Infrastructure Transition Programme to announce a future-forward plan to harness energy from wastewater through a combination of technologies – generating low-carbon heat and energy cost savings to public buildings and businesses in Stirling, Scotland.
A first of its kind
The inventive process is the first of its kind in the U.K. – using sewage and wastewater heat recovery technology alongside a combined heat and power engine to generate heat and electricity in one single, highly efficient process.
Utilizing the Trane® CITY Booster heat pump with ultra-low global warming potential refrigerant, low-carbon heat from sewage and wastewater is extracted and delivered to the area’s heating and cooling grid, including a nearby high school, stadium and activity center. Possible future expansion may extend across the city, providing energy cost savings to households and additional local businesses.
The project has the potential to save over 380 metric tons of carbon per year – equivalent to driving 1.5 million miles, or from Stirling, Scotland to New York, NY nearly 465 times.
“The Stirling Project is a key example of how we’re supporting the Scottish Government and Scottish Water in their ambitious net-zero emissions targets,” said Donald MacBrayne, business development manager for Scottish Water Horizons. “Over half of the energy consumed in Scotland comes from heat, and we are dedicated to continuously utilizing Scottish Water assets to contribute to a greener Scotland.”
