Up and down the I-5 Corridor, transit agencies (TAs) large and small are evaluating alternatives to reduce the greenhouse gas (GHG) and criteria pollutant emissions of their fleets. For a variety of reasons, many TAs are coming to the realization that they should not rely entirely on any single alternative fuel as they seek to […]
In North America, we rely on natural gas to provide the majority of our space and process heat. It is also safe to assert that, in most cases, the next MegaWatt hour will be generated through the combustion of natural gas. For example, 80% of the heat used for food processing is derived from natural […]
Join the NW Alliance for Clean Transportation on Wednesday, September 9, from Noon – 1:00 PM, for the first of three September Seminars. Learn from Ameresco, DMT Clear Gas Solutions, and Live Oak Bank about what is required to take an RNG project successfully from start to finish. Ameresco has built more than 40 biogas projects, […]
PART I of II The transportation sector has entered a period of dynamic change. For roughly a century, we have propelled ourselves with internal combustion engines that burn liquid fossil fuels. At present we are evaluating a menu of fuel choices to drive us into the future, including propane, electricity, hydrogen fuel cells, and natural […]
PART II of II Why Natural Gas? Natural gas is a proven technology that is cost-competitive and reduces both criterion air pollutants and GHG emissions. CNG and RNG are well-suited for use in congested areas where human health is compromised due to poor air quality. This is because CNG and RNG reduce criterion air pollutants, […]
New NGV engines are cleaner than alternatives. The Cummins Westport Ultra-Low NOx engine is 90 percent cleaner than the latest available diesel engine. It beats electric motors based on full fuel-cycle comparisons. Natural gas vehicle fuels reduce greenhouse gas emissions. A vehicle operating on liquefied natural gas (LNG) emits 11 percent less CO2 than a […]
