Summary:
The feasibility of liquefied natural gas (LNG) as a fuel for railroads is investigated. The documented relevant technology developments include LNG-fueled locomotives, LNG tender cars, and refueling equipment. Current demonstration projects and LNG railroad economics are also reviewed. The most mature LNG engine technology is a diesel conversion employing low-pressure gas injection with diesel-injection pilot-ignition. Locomotives with these engines and LNG tender cars are currently undergoing field tests. An economic assessment based on life-cycle cost analyses is carried out for two high fuel consumption scenarios: a unit bulk train and a high speed intermodal train. Capital and operating cost estimates are developed for all aspects of the LNG supply system and railroad equipment. The resultant LNG versus diesel life-cycle cost comparison is expressed as a function of the two most critical input cost elements: the price of natural gas feedstock and the price of diesel fuel. The sensitivity of the LNG versus diesel life-cycle cost comparison to various input assumptions is quantified. High fuel consumption and highly utilized central refueling facilities are characteristics that make railroads good candidates for LNG technology.
