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
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.”
