Californian Research Team Reassesses SCR Effectiveness for HGVs

| USA

USA_UC Riverside Report for CARB re SCR May2017Despite the dramatic progress year on year with reducing emissions in the USA, the U.S. EPA says air pollution continues to threaten Americans’ health and welfare. Furthermore, emissions from the transportation sector are comparatively on the rise, now claiming first position amongst contributing sectors. A new study prepared by UC Riverside’s College of Engineering and published by CARB last week suggests SCR technology is less effective, vocation-specific and requires further research to determine the frequency of good SCR function needed to obtain real-world NOx emissions data.

Cleaner and Economic Outcomes for California using RNG for HDVs, Study Shows

California Study 2017 coverA California-generated new jobs study reveals that deploying trucks fueled by renewable natural gas (RNG) could create up to 130,000 new jobs and add $14 billion to California’s economy. The ‘RNG Jobs Report’ examines the economic potential of fueling heavy-duty trucks with renewable natural gas produced in California, instead of being powered by petroleum-based diesel. Read more »

The University of California Riverside’s College of Engineering – Center for Environmental Research and Technology (CE-CERT) has released a report that summarises clear benefits should California promote the uptake of heavy duty natural gas trucks to meet its objective of reducing transport-related emissions, particularly when compared to equivalent diesel-operated HDVs. It sees natural gas powered vehicles as significant contributors that will assist the South Coast Air Basin and California to reach federal air quality attainment standards. Read more »

IGU Case Studies: Natural Gas – Cleaner Cities

(Source: IGU)

“The use of natural gas as a fuel for both road and marine transport pioneered in Berlin and Rotterdam shows that the positive impact of natural gas goes well beyond the more well-known use as a fuel in power and heat generation.” — IGU Case Studies in Improving Urban Air Quality – New edition

The economic cost of air pollution is astronomical; its indiscriminate and widespread impact humanity has upscaled health issues, not just in cities, where it is most evident, but along highways, coasts and elsewhere. It has no regard for borders and pays scant heed to diminutive policies and selfish objectives. One solution on the path to addressing this global issue is the increased use of natural gas, says IGU, which has released a new edition of case studies depicting efforts to bring about change.
