Economic analysis of low-pressure natural-gas-vehicle storage technology. Task 3 topical report, March 1989-April 1990

Abstract: The economic analysis concludes that, under the assumptions of the base case, a low pressure adsorbed natural gas (ANG) system for vehicle fuel storage is a viable and competitive alternative to compressed natural gas (CNG) storage systems. ANG systems offer the ability to reduce compressor capital and operating costs, and eliminate costs associated with periodic recertification of CNG storage cylinders. The only cost element to realize and increase due to ANG is the vehicle fuel storage apparatus. Specifically, the cost for purchasing adsorbent carbon becomes the most significant additional expenditure.

Gas-Fired Natural Gas Liquefier for Vehicle Fuel

Abstract: A Stirling-Stirling natural gas liquefier will be developed, in which a gas-fired Stirling engine drives a Stirling cryocooler to condense pipeline gas to liquid natural gas (LNG) for use as a vehicle fuel. There is a very large prospective market for such a device wherever pipeline gas is available throughout the world. Natural gas offers many advantages over gasoline, diesel and alcohol vehicle fuels, including lower vehicle operating and maintenance costs, smoother, quieter operation, cleaner combustion with less pollution, increased safety, and an ample domestic supply for reduced dependency on imported oil. LNG is preferable to compressed natural gas (CNG) as a vehicle fuel because of the savings possible in the size, weight and cost of the vehicle tank.
