A new boiler plant at Southwestern Vermont Medical Center cleared local permitting this week, but state regulators still need to sign off on the project.
Development Review Board members on Tuesday approved the site plan for a new central heating plant, a $3.75 million project that SVMC officials estimate would save $200,000 a year and lower the hospital’s carbon emissions. Oil-fired boilers would be replaced with more efficient units that burn natural gas, with the option to someday use biomass and wood, according to plans filed with the state.
SVMC has applied for a “certificate of need” from the Green Mountain Care Board (GMCB), the state’s health care regulatory board, which must approve major healthcare projects. The board held a public hearing in Montpelier on Oct. 27 that a handful of hospital officials attended, according to the board’s website.

New Hampshire state officials recently celebrated National Bioenergy Day by holding an open house to recognize the completion of a new wood biomass boiler that will heat a major state building in Concord.
The New Hampshire Department of Environmental Services and the Department of Health and Human Services facility on Hazen Drive in Concord will be heated this winter with sustainably sourced local wood biomass chips instead of natural gas.
The project was completed through an innovative financing mechanism in partnership with ConEdison Solutions, a national energy services company. It is part of a comprehensive $12.7 million energy efficiency and renewable energy upgrade for facilities in the Meldrim Thomson State Office Park East.

In colder weather, people have long been warming up around campfires and woodstoves. Lately, this idea of burning wood or other biomass for heat has surged in popularity as an alternative to using fossil fuels. Now, in the journal ACS Sustainable Chemistry & Engineering, scientists report a step toward a “greener” way to generate heat with biomass. Rather than burning it, which releases pollutants, they let fungi break it down to release heat.
The benefit of biomass, which consists of plant material and animal waste, is that there is no shortage. It is produced continuously in enormous quantities as a waste product from paper and agricultural industries. But burning it emits fine particles and volatile organic compounds, or VOCs, linked to health and environmental problems. So scientists have been trying to figure out how to use biomass with minimal emissions. One approach involves adding microorganisms that can degrade the materials. In this process, heat is released without giving off fine particles or VOCs. So far, most investigations into this method have involved room-temperature conditions. But for sustained use, these reactions would need to take place at temperatures above ambient conditions as heat is produced. Leire Caizán Juanarena and colleagues wanted to warm things up to see how much heat they could coax out of the process.
