How does eSteam™ work?

Vicinity will use a combination of heat pumps, electric boilers, and thermal storage technologies to create carbon-free eSteam™.

1. Procure

Vicinity will procure electricity from renewable, carbon-free energy sources and import the power through a co-located electric substation.

2. Produce

Powered by green electricity, electric boilers and industrial-scale heat pumps will transform water into eSteam™. 

3. Optimize

Thermal storage will store eSteam™ for use during peak demand.

4. Distribute

Carbon-free eSteam™ will be distributed to customers through underground piping infrastructure.

Industrial-scale heat pumps to cut carbon

Vicinity is engineering a low-temperature source heat pump system for eSteam™ generation. In the next few years, we are installing an industrial-scale heat pump complex at our Kendall facility in Cambridge, MA.
