Just this week, the Coalition for Renewable Natural Gas (RNG Coalition) announced that the North American renewable natural gas (RNG) industry has reached the 100 facility benchmark this summer. With the addition of three recent operational facilities, the 101 RNG production sites across the continent, (91 in the United States and 10 in Canada), equate to nearly 150% growth over the past five years from the 41 projects built between 1982 and 2014.
While RNG or biogas plants have obviously been around for a long time in the United States and Canada, an acceleration in development is apparent. Technological developments, specialist operators and state legislation promoting biogas development, are all contributing to a wave of larger-scale facilities, invariably linked to pipelines rather than simply meeting on-site demand.
Pig and dairy farms feature prominently as locations in the current wave of projects, with developers such as Dominion, California Bioenergy, Vanguard Renewables, GESS International and Calgren Dairy Fuels announcing large deals with livestock producers, such as Dominion’s November 2018 announcement to tie up with Smithfield Foods, the world’s largest pork processor and pig producer.
AcuComm currently lists 196 biogas/AD active projects in the United States and Canada in its database.
