Propane's ability to be stored and transported as a liquid is one of its most important advantages. Because propane is more compact as a liquid than as a gas, large quantities can be transported and stored using a variety of methods, including large underground caverns, large and small above-ground tanks, below-ground tanks, and cylinders.
Tank and container designs and specifications affect how propane equipment is designed and used. They also ensure safe storage and convenience in refueling. Flexible storage options allow propane to be stored and/or used safely underground and in areas beyond gas mains. The continued development of a variety of storage technologies enables further market expansion into residential, commercial, and remote applications.
PERC's storage research program has supported the development, demonstration, safety testing, and/or commercialization of propane storage technologies including:
- lightweight composite cylinders
- composite underground tanks
- stop-fill sensors
- vapor regulators
Cylinder
Cylinder research explores the development of new cylinder designs and uses, and performs extensive fire testing on cylinders to ensure consumer safety.
Tank
Tank research explores the development and safety of new and existing tank designs. It focuses on developing tanks to be lighter, more durable, and/or longer-lived, and includes studies of tank behavior in fires and alternative tank materials.
Valve/Regulator/Gauge
Valve/regulator/gauge research explores the performance of valves, regulators, and gauges, and their impacts on safety and reliable product delivery. It develops technologies that enhance the protection of downstream propane equipment and appliances, and also improves inventory management.
