Vermont’s only gas utility wants to offer more RNG to customers in response to demand for decarbonization.
In early 2018, Vermont Gas became the first local gas distribution company in the country to give customers the option to purchase renewable natural gas.
About 60 customers have since signed up for the voluntary program, including large businesses such as Seventh Generation and the Vermont Coffee Company. They pay a premium that averages about 10% for the fuel’s renewable attributes and can choose to ramp up the amount they purchase over time.
Renewable natural gas, or RNG, is produced from the anaerobic digestion of animal manure, food waste, and other organic waste. Once it’s conditioned and upgraded for injection into pipelines, RNG can actually be higher quality — nearly pure methane — than fossil-derived gas. And just like natural gas, it can be burned to produce electricity, heat homes or fuel vehicles.
