eSteam™: a cost-effective, carbon-free thermal energy solution to decarbonize your commercial building
Pumps & Systems podcast: Heat pumps & decarbonization
In this episode of the Pumps & Systems podcast, Bill DiCroce, President and Chief Executive Officer of Vicinity Energy discussed the role heat pumps can play in decarbonization, as well as the efforts cities like Boston are currently making to strive for sustainability and an eventual goal of net zero carbon emissions.

Heating reimagined: industrial-scale heat pumps for building decarbonization
Revolutionizing the way we heat buildings by integrating industrial-scale heat pumps to produce carbon-free eSteam™
Industrial-scale heat pumps are revolutionizing the energy industry. With the ability to produce temperatures of up to 150C, these powerful systems have become a sustainable solution across the globe. As the demand for carbon-free heating increases, the shift away from fossil fuels is finally gaining momentum.
Vicinity is transforming district energy with plans to install an industrial-scale heat complex. This innovative heat pump complex will draw heat from nearby water sources to generate steam and improve the system’s efficiency. Ensuring that the river and its ecosystems remain unharmed, the river intake system lifts heat from the river and brings it into our facilities.
Key facts
- The proposed Cambridge heat pump will have a steam export capacity of 35MW (thermal)
- The heat pump will occupy a space of approximately 25,000 sq ft. +/-
- The heat pump will circulate through 24.5 million to 49 million gallons of water from the Charles River daily
How heat pumps work
- River water is pumped into the evaporator to warm the cold refrigerant.
- Renewable electricity powers the compressor to pressurize the refrigerant.
- Hot, pressurized refrigerant creates low-pressure carbon-free eSteam™ from feed water.
- A multi-stage steam compressor increases the pressure of the eSteam™ for distribution.
- The refrigerant is cooled and depressurized for the next cycle.
- Cooled water is returned to the river, and the process repeats.
How Vicinity is using heat pumps
Industrial-scale heat pumps will be installed in cities around the country where Vicinity’s facilities are located near water sources and already employ water intake systems. These heat pumps will extract heat from adjacent water sources, like the Charles and Schuylkill Rivers, to generate steam and improve the system’s overall efficiency.
Across all of our operations, heat pumps will be used with electric boilers and thermal storage technologies to fully decarbonize our operations.
This first planned heat pump complex in Cambridge will be powered by renewable electricity to efficiently harvest energy from the Charles River and return the water to a lower temperature.
Why industrial heat pumps are important for Vicinity, our customers, and the environment
The global energy transition can only succeed with decarbonizing heat. Why? Heating in buildings is responsible for four gigatons (Gt) of CO2 emissions annually—10% of global emissions, according to the International Energy Agency (IEA). The heating sector accounts for 30-40% of CO2 emissions globally.
Water-source heat pumps are a proven solution to fossil- fuel-driven heating because they can efficiently harness the renewable power of water sources.
In 2021, approximately 10% percent of the global demand for space heating was satisfied by heat pumps. In some countries such as Norway, Sweden, and Finland, heat pumps are the most widely used heating source and have already begun integrating with district energy systems. The district system in Glasgow will leverage heat pumps to extract cold water from the adjacent River Clyde. This will cover over 80% of building heat demand and will deliver immediate carbon reductions of 50%.
By installing industrial-scale heat pumps at our central facilities, Vicinity is one step closer to instantly decarbonizing millions of square feet of building space for the good of our customers, communities, and the cities we operate. The impact of this plan is substantial: by 2035, Vicinity’s investments at our Kendall, MA facility will reduce the carbon intensity of our steam by 50%, the equivalent of 400,000 tons.
