It’s clear that the HDV sector is headed in the right direction
With South Korea set to introduce new greenhouse gas emissions legislation for vehicles by 2019, the Second Integer Emissions Summit and AdBlue Forum Asia Pacific 2017 in Seoul provided a venue for discussions on more stringent standards for heavy-duty vehicles.
The summit, held from April 5-6, involved representatives from government, the private sector and research organizations who explored new emissions control technologies and policy-based market and industry development strategies.
In an overview of the Asia Pacific heavy-duty vehicle market, Tim Cheyne, Director of Emissions at Integer Research, said truck and commercial vehicle sales in select markets in Asia and the Pacific were expected to grow from 2.6 million in 2016 to 3.1 million by 2022 – or about 19 percent in six years.
Mr Cheyne said emission standards for heavy-duty vehicle (HDVs) were becoming more stringent, and the introduction of Euro VI standards was an opportunity to standardize such technology options as selective catalytic reduction (SCR) and diesel particulate filters (DPFs) to increase market penetration.
He said more emphasis on climate change was also expected with the ratification of Intended Nationally Determined Contributions for many countries in the region.
Dr Tue Johannessen, Chief Technology Officer at Amminex Emissions Technology, said SCR was important in driving down tailpipe NOx emissions to meet Euro VI standards. He said Ammonia Storage and Delivery Systems (ASDS) ensured more efficient NOx conversion to control tailpipe NOx emissions in urban driving conditions. The technology was both safe, with regular quality assurance and quality control protocols, and could be retrofitted in commercial vehicles.
Mauro Zorzetto, Research and Development Manager at the Eltek Group, exhibited newly developed SCR sensing devices that functioned at -40C to ensure reliable measurements of SCR relative pressure in sub-zero conditions.
During the “Perspectives on Optimal Strategies for Meeting Emissions Targets” panel discussion, which focused on the best routes to a low-emission heavy-duty vehicle sector, Clean Air Asia Transport Researcher Mark Tacderas discussed the impacts of road freight emissions and policy-based solutions.
Mr Tacderas said emission control technologies required fuel quality for maximum benefits, with fuel sulfur content affecting the performance of such devices as DPFs, prompting the need for standards.
He also highlighted Clean Air Asia’s work in setting up green freight programs in Asia which, as a market-based strategy, encouraged collaboration between governments, the private sector and stakeholders in lowering emissions from freight through assessment and evaluation of the freight sector, benchmarking, technology verification and financial support mechanisms.
“There’s no one-size-fits-all solution to promoting green freight transport,” Mr Tacderas said. “Market-based solutions that encourage modern technologies to flourish will play key roles, such as fuel economy policies and fuel quality standards.
“And while it will be a challenge to implement support mechanisms, such as new testing protocols and facilities, and even more of a challenge for developing economies, it’s clear that the HDV sector is headed in the right direction.”
