Transportation fact of the week #1025

China’s Plug-in Vehicle Market Share was More Than Double That of the U.S. for 2017

Plug-in electric vehicle (PEV) sales in China began to grow rapidly after 2013, increasing from 0.1% to 2.3% of all new vehicle sales by 2017, mainly due to government monetary incentives and increased availability of PEV models. The growth of PEV sales in the U.S. has been more gradual, reaching 1.1% of light vehicle sales in 2017. Total PEV sales in China were about 550,000 vehicles in 2017, while U.S. PEV sales were just under 200,000. The share of all-electric vehicles (BEV) to plug-in hybrid vehicles (PHEVs) sold in China were much different than in the United States.  In China, 81% of PEV sales were BEV in 2017, while in the U.S., BEV accounted for just over half (53%).

NGV Global: Natural Gas Regulations Update

April 20, 2018 | International | Source: NGV Global


Agility Fuel Solutions ProRail CNG System

Globally, natural gas mobility is an evolving industry that continues to thrive, expand and consolidate despite market challenges. Natural gas vehicles (NGV) operate in more than 80 countries and natural gas propulsion is taking vessels along inland waterways and across oceans. Regulations and standards are a vital component of this industry.

Such is the context in which several documents were tabled at the UNECE Group of Experts on General Safety (GRSG) meeting on 10-13 April 2018 in Geneva. NGV Global was in attendance to ensure the best interests of the worldwide natural gas for transportation industry were kept to the fore. Discussed were proposed changes to UNECE R.110 (CNG/LNG Vehicles) including CNG cylinder inspections, and expansion to applications for on-board vehicle appliances.

NGV Global brings considerable expertise to these meetings, confirming its ongoing commitment to ensuring best practice for the industry. The Association, now more than 30 years since inception, participates on no less than 14 ISO committees covering gaseous fuels technology, ships and marine technology, cryogenic vessels, cylinder design, measurement, classification and more.

For the majority of these forums, NGV Global is the only participant with a global natural gas overview, particularly for land-based transportation (road, off-road, rail). Harmonisation is vital for all industry stakeholders, but particularly OEMs, component manufacturers and global suppliers. Without this perspective, each country would introduce and enforce its own unique requirements, making the costs of implementation and growth strategies astronomically expensive. One major stakeholder has estimated that annual cost to be in excess of USD 100,00 per annum.

In addition, NGV Global represents the industry on three UNECE Working Groups, of which GRSG is one. Our UNECE activity falls under UNECE World Forum for Harmonization of Vehicle Regulations (WP.29) which is a unique worldwide regulatory forum within the institutional framework of the UNECE Inland Transport Committee.

ECE R.110

The Geneva meeting is the latest in a series of meetings seeking to resolve issues pertaining to CNG cylinder inspections. The same regulation applies to LPG tanks. Other participants in discussions include contracting parties, NGOs, and equipment and vehicle manufacturers.

Out of these meetings has come an amendment to R.110, now adopted, that requires new designs for protective covers on CNG cylinders so that they can be opened without the use of tools in order to expose the cylinder for inspection.  Tools such as lights, mirrors and endoscopes are allowed in order to view those parts of cylinders that might be obscured due to the manner in which it is mounted either on the exterior or interior of the vehicle.  New designs for CNG cylinder protective covers will be required for retrofitters by September 2019 and for vehicle approval (OEM vehicles) by September 2021.

There has been some discussion also about a proposal to entirely remove dome covers for Type IV cylinders for inspection purposes. Such a change could impact all composite cylinder manufacturers. The proposal is not without cause but requires further investigation.

A proposal was adopted to harmonize R.110 with ISO regarding CNG cylinder testing procedures and was due to a transposition error in the table that otherwise would have affected these procedures.

R.110 was proposed for amendment by the addition of terminology covering new requirements for components used in LNG/CNG systems such as a ‘CNG accumulator’ and a ‘CNG compressor’.

R.110 terminology with respect to the regulated inclusion of a gas flow adjustor was introduced by OICA, the Association of International Car Manufacturers, for future amendment.

Add-ons to Vehicle System

Natural gas heaters and refrigeration systems are already permitted under existing provisions. It has been proposed to add a natural gas-fired generator to this list, providing power for the driver in sleeper cabs overnight or to maintain battery charge during high electrical power use with loading or lifting equipment, etc.

The change is specifically for Liquefied Natural Gas (LNG)-powered trucks in order to reduce the tank pressure and to prevent or delay venting.

The Power of Membership

The avenues for making regulatory change are restricted by a challenging trio: cost, location and rules. The advantage of an international association such as NGV Global rests in its experience, longevity and wealth of knowledge, commanding respect in international forums.

Members of NGV Global and its Affiliated Associations (NGVA Europe, NGVAmerica, ANGVA (Asia-Pacific), KANGV (Korea), NGV Italy, CAGNC (Argentina) and NGV Ukraine are able to participate in the regulations and standards development process, making a real difference where it matters.


The International Organization for Standardization (ISO) is an independent, non-governmental organization with a membership of 161 national standards bodies.

The United Nations Economic Commission for Europe (UNECE) includes 56 member States in Europe, North America and Asia. However, all interested United Nations member States may participate in the work of UNECE. Over 70 international professional organizations and other non-governmental organizations take part in UNECE activities.

NGV Global is The International Association for Natural Gas Vehicles. Information about NGV Global’s involvement in standards and regulations can be found at Inquiries welcomed by email to

Currently there are more than 25 million vehicles operating around the world. See NGV statistics here.

Former EPA admin gives talk at UNM

By Danielle Prokop 4/25/18

The glasses came off, and on and no punches were pulled.

Gina McCarthy, the former administrator for the Environmental Protection Agency under President Barack Obama, gave an animated speech to community members at the University of New Mexico School of Law about the concerns of climate change Wednesday evening.

The focus of the speech was reframing how climate change and policy is discussed.

“Stop talking about the health of the planet. The planet could give two — sorry I’ll be polite — the planet doesn’t care if the climate is changing, it remains a planet. We should care, because people might not be living on the planet,” McCarthy said while gesticulating.

Almost 200 people watched the speech from the rows of white chairs set up in the law school’s lobby. The speech was punctuated with bouts of laughter from the audience as she flung jokes from the podium.

However, McCarthy also touched on the more serious concerns of climate change, including air pollution, drought and fears of not producing enough food.

One issue that came up was repeal of the EPA Clean Power Plan, proposed by Scott Pruitt, the current EPA administrator under President Drumpf. Apple, Google and other companies have publicly condemned the repeal of the policy, a legacy of Obama’s to curb carbon emissions.

Tabling at the event was Tere Baca, an intern with Environment New Mexico. She was representing a coalition of environmental groups collecting public comments on the repeal.

“The period for public comment closes (Thursday) evening, so this is really urgent and timely,” Baca said.

The Clean Power Plan was expected to cut power sector emissions by 32 percent by 2030. Power plants fueled by coal and natural gas are responsible for one-third of the United States’ carbon dioxide emissions, according to the EPA.

McCarthy spoke for just over a half hour and dedicated another half hour to answering questions from the audience.

The first question from the audience was about McCarthy’s position on fracking.

She said that inexpensive natural gas changed the economic dynamic of coal and oil based power plants and helped push through clean air regulations, but the industry has to “grow up just a little bit” and adhere to cleaner standards.

“I think that states need to have regulations that are stringent on fracking,” McCarthy said. “You have the same obligations as any other industry standards have. You don’t contaminate the groundwater (and) you don’t release methane, especially when it’s your product.”

Fracking has been a controversial issue in New Mexico. Literature from the industry describes fracking as a method to extract oil and natural gas. The process includes drilling outward from a wellhead injecting liquid at high pressures to force fissures into rocks and boreholes.

According to the New Mexico Legislature, oil and gas typically provides the state around $2 billion in direct revenues.

Advocates say the process is more environmentally friendly as opposed to traditional vertical drilling into the ground. Critics say the the method is known to create earthquakes, and the EPA reported in 2014that fracking affects drinking water.

McCarthy also directed her comments to the University students in the audience, saying that college campuses are the future of developing sustainably.

“You are our conscience. You tell us what you need. You are the people we should be working for,” she said.

Some of the attendees included second-year law students of the Natural Resources Journal, a publication that collects policy writings on energy and the environment.

Jimmy Grieco is a co-lead citation editor at the journal and said the speech helped emphasize how important writing about environmental policy is at the University level.

“It’s critical now because of the timeliness of the environmental challenges occurring right now,” Grieco said. “It’s important to do this work at universities, because we are able to bridge the gap between the professionals who write about it and the students who read about it.”

McCarthy ended her speech with a challenge to the audience not to just talk about climate change, but to take action by voting and advocating.

“Pull up your big-girl pants, your big-boy pants or your gender-neutral pants and do something — we’ll all be better for it,” she said.
