Cogenerated "Green Steam" reduces carbon footprint in Boston and Cambridge
Located beneath the streets and bridges of Boston and Cambridge invisible to the cities above is a network of district energy steam pipes delivering environmentally friendly thermal energy or "Green Steam" throughout the Boston-Cambridge system."Green Steam" is an innovative environmental solution that recaptures and reuses thermal energy previously lost to the environment, utilizing advanced cogeneration technology. Following the completion of a 7,000-foot steam pipeline extension in 2013 and a planned reconfiguration of the recently acquired Kendall Station, up to 75% of Veolia's district energy heat supply will consist of recycled "Green Steam."This innovative $112 million, "Green Steam" investment generates significant benefits for Cambridge and Boston, including:
- Significant reduction in greenhouse gas emissions in support of the Greenovate Boston goal of reducing Boston's greenhouse gas emissions 25% by 2020 and 80% by 2050;
- A 6% reduction of non-transportation carbon emissions for both cities
- Minimizing thermal pollution from the Charles River ecosystem;
- Improving air quality, reducing NOx and SO2 emissions by approximately 36% and 61%, respectively;
- 311, 936 labor hours supported the construction of the “Green Steam” project;
- Increasing capacity, reliability and overall system efficiency;
- Supporting sustainable development in both Boston and Cambridge; and
- Increasing the region's energy reliability.
In Boston, Veolia supplies thermal energy to commercial, government, institutional and hospitality customers, including 70% of Boston's high-rise buildings. Up to 75% of the steam supplied to the Boston network is cogenerated "Green Steam" imported from the Kendall Station plant located in Cambridge.
In Cambridge, Veolia manages a steam distribution network, in addition to recently acquiring the 256-megawatt Kendall Station in 2013 with partner I Squared Capital. Located in the high-tech corridor near Harvard University and the Massachusetts Institute of Technology (MIT), the network supplies cogenerated "Green Steam" to global leaders in biotechnology, pharmaceuticals and healthcare.
Veolia also operates a cogeneration plant on behalf of a major biotechnology company, providing comprehensive operation and maintenance of the central steam/electricity generation plant.
