2015 CH4 Connections Conference Includes Panel Discussion on Benefits of NGVs
On Wednesday, NGVAmerica’s Jeff Clarke participated on a panel with AGA’s Dr. Kathryn Clay, GNA’s Patrick Couch, and HARC’s Dr. Yiqun Huang. Jeff Clarke presented information on the greenhouse gas and other emissions benefits of NGVs. The conference was sponsored by GTI and the Houston Advanced Research Center (HARC). NGVAmerica’s presentation included details on Cummins Westport’s recent certification of the ISLG 8.9 liter and ISB 6.7 liter engines, both of which have been certified to extremely low emissions levels for nitrogen oxides (NOx). In the case of the ISLG 8.9 liter, the engine provides about 95 percent reduction in NOx emissions over its diesel counterpart. Jeff Clarke also presented recent greenhouse gas figures released by California as part of the rulemaking to reauthorize the Low Carbon Fuel Standard. Dr. Clay addressed on the policy considerations and benefits of using natural gas, emphasizing the growing resource base here in the U.S. Patrick Couch focused on opportunities for reducing emissions at natural gas fueling stations, and also the significant environmental benefits of combining renewable natural gas and low-NOx natural gas engines. Dr. Huang presented data on dual-fuel engines used by natural gas producers to support drilling sites. The presentation indicated some dual-fuel engines should be better optimized and equipped with after-treatment to lower emissions.
