BYD Electric Buses Plagued With Problems.

BYD has been manufacturing electric buses in Lancaster, California, for the past nine years, but they are contending with a record of poor performance. Actual driving ranges are dozens of miles short of what is claimed. The first five buses sold to L.A. Metro were pulled off the street in less than five months. Agency staff found they were unreliable for 100 mile distances.

When BYD delivered its first five buses to L.A. Metro in 2015, they had immediate problems. They would stall on hills. BYD had promised a range of 155 miles per charge, but in reality the range averaged only 59 miles. In most months, the buses required road calls after less than 400 miles. L.A. Metro deemed them unsuitable after four months. BYD offered to take them back. BYD accused L.A. Metro drivers of taking their BYD buses on hills that were too steep, and they made unnecessary road calls. L.A. Metro also cited delays for parts.

Problems with doors on BYD buses have been reported in Anaheim and Denver. Cracks in frames appeared during federal endurance testing last year.

Growth of Natural Gas Use in Vehicles Expected

Due to "a prolonged period of stable diesel fuel prices and new competition emerging from electric vehicles", some of the excitement about natural gas as a transportation fuel has subsided in recent years. But there are some developments that could bring back that excitement. One is the new Cummins Westport ISX 12N engine which will provide natural gas users with unprecedented performance and efficiency. That, plus extended engine oil intervals and a growing fueling infrastructure will bring renewed interest in natural gas.

The 2017 income tax measure approved retroactive tax credits for vehicles and refueling infrastructure.

The refuse industry has been adding natural gas vehicles in "significant volume." Sales of natural gas vehicles are expected to increase 10% annually. "Clean Energy Fuels reported demand for its Redeem RNG product grew 32% during 2017."

"UPS announced an agreement with Big Ox Energy to purchase 10 million gallon equivalents of RNG a year. During 2017, the Atlanta-based parcel giant announced a planned investment of more than $90 million for six additional CNG stations, 390 new CNG tractors and terminal trucks, and 250 LNG vehicles."

Clean Energy won a four-year fueling contract from Ryder for a fleet of LNG heavy duty trucks used by Toyota Motor Corporation in Kentucky. They expect to supply 380,000 GGE of LNG annually to Toyota.

Last year, Nestlé Waters North America added 155 Ford F-650 delivery trucks that run on propane autogas, bringing its total to 600, or 30% of its total North American fleet.

Improved User Interface for Alternative Fueling Station Locator

Clean Cities has announced an upgrade to their Alternative Fuels Data Center (AFDC) Station Locator. You can find the upgraded Station Locator here.
Some of the notable new features include a sleek look and feel, simplifying the user experience, as well as a bigger map populated with consistent circle icons for each station location and updated colors representing each fuel type. Users will also notice a larger and more detailed view of specific station information.

On the Station Locator home page, there are now two tabs at the top of the map: Find Public Stations and Analyze and Download Data.

The Find Public Stations tab allows users to search for public stations at a specific location, with the option to search for all fuels or just one.

The Analyze and Download Data tab allows users to refine their search using filters, broken out into three categories: Location, Fuel, and Station.

VOC Recovery System Will Save 3,000 Tons Of Fuel Annually On Shuttle Tanker

Wärtsilä announced it will supply its Volatile Organic Compounds (VOC) recovery technology, LNG fuel gas handling systems and the auxiliary engines for two new shuttle tankers being built for Singapore based AET Tankers at the Samsung Heavy Industries shipyard in South Korea. VOC – the gas evaporating from the oil cargo tanks – will be recovered and mixed with the tanker's LNG fuel. This will save more than 3,000 tons of LNG per year per vessel, plus enabling significant reductions in CO2.

Hog Farm Emissions in North Carolina Captured For RNG

Duke Energy, in North Carolina, is using renewable natural gas from hog farm methane to generate electricity. A North Carolina law requires Duke Energy to produce 0.2% of its retail sales from swine waste by 2023.

"CSA Group Publishes New NGV Standard for Fuel Storage and Delivery"

From NGVAmerica News:
CSA Group has published the second edition of CSA/ANSI NGV 6.1, Compressed Natural Gas fuel storage and delivery systems for road vehicles. A CNG fuel system standard was included as a priority on the 2016 US Department of Energy and Natural Resources Canada’s Natural Gas Vehicle Work Plan, in support of the Regulatory Cooperation Council. To meet this need, CSA Group worked with the North American natural gas vehicle industry to transition the bi-national recommended practice, CSA/ANSI NGV 6.1 – Compressed Natural Gas (CNG) Fuel Storage and Delivery Systems for Road Vehicles, to a bi-national standard recognized in the US and Canada by ANSI and SCC, respectively.

“NGV 6.1 fills a gap that the NGV industry has been missing for years,” said Dan Bowerson, Director of Technology & Development, NGVAmerica and Co-chair of NGV 6.1. “By using system engineering practices and starting with a system level FMEA, the NGV 6.1 Technical Subcommittee was able to focus on safety needs of the CNG fuel storage and handling systems. The Technical Subcommittee developed a standard that will be useful for companies or individuals involved in the design and installation of CNG systems and components.”

The first edition of CSA NGV 6.1 was a Recommended Practice that provided a recommended standard practice for vehicle fuel systems. It was written in mandatory language to accommodate its adoption by anyone wishing to do so. The second edition transitioned to a National Standard.

400 Or More Diesel Trucks To Be Replaced With Natural Gas Trucks

The South Coast Air Quality Management District (SCAQMD) in southern California has received 400 applications for a share of $21 million to replace 400 or more heavy duty diesel trucks with heavy duty natural gas trucks. That would be the equivalent of taking more than 22,000 passenger vehicles off the road. Fleet owners seeking to replace diesel trucks may be eligible for up to $100,000 towards the purchase of a new natural gas truck.

The money comes from California's Prop 1B, approved in 2006, which, among other things, is intended to reduce emissions of diesel particulates from vehicles that use the state's ports.

SoCalGas provided assistance to SCQAMD with the applications. More info can be found in this article at NGVAmerica.
