An alternative to gasoline and diesel fuel that is being heavily explored in the automobile industry is hydrogen gas. The conversion of hydrogen gas into electricity only emits water and heat as a by-product, effectively negating any tailpipe pollution. ANSI HGV 2-2014 (R2019) – Compressed hydrogen gas vehicle fuel containers was developed by the Canadian Standards Association (CSA) and approved by the Joint Automotive Technical Committee. The standard defines material, design, manufacturing, marking, and testing requirements for serially produced and refillable Type HGV2 containers used to store compressed hydrogen gas for on-road vehicle operation.
The most significant long-term environmental challenge facing the United States and the world is climate change that results from anthropogenic emissions of greenhouse gases (GHGs). These changes come with far-reaching consequences and real economic costs. In 2012 alone, there were 11 different climate disaster events across the U.S., with losses exceeding $110 billion in estimated damages.
Although no individual event can be attributed to climate change alone, rising greenhouse gas emissions are affecting many regions of the country and virtually all economic sectors. In 2015, the transportation sector was responsible for 27% of greenhouse gas emissions, second only to the electricity sector. According to the U.S. Department of Transportation, greenhouse gas emissions from transportation have increased by over 27% since 1990, mainly due to a combination of greater demand for travel and inadequate gains in fuel efficiency.
Hydrogen fuel is a zero-emissions alternative to gasoline and diesel. Compared with battery-electric vehicles, which recharge by plugging in, the combination of fast, centralized refueling and longer driving ranges make hydrogen gas fuel cells particularly relevant for larger vehicles with long-distance requirements or for drivers who lack plug-in access at home.
ANSI HGV 2-2014 (R2019) indicates that the fuel containers should
a) be permanently attached to the vehicle
b) have a capacity of up to 1,000 liters water capacity
c) have a nominal working pressure that does not exceed 70 MPa
The information covered in ANSI HGV 2-2014 (R2019) provides detailed specifications to guide the construction of safe and efficient hydrogen gas containers, including service conditions, material qualification tests and requirements, container wall thickness, inspection requirements, manufacturing processes, production verification requirements, batch testing, and quality assurance.
