In this study, various steps involving hydrogen production from biogas, its storage and transportation, and its marketing as a commodity have been reviewed. Various scenarios have been studied, and design and cost relationships have been developed for feasible alternatives. A case study has been carried out for India, and an economic assessment has been presented. It is found that the hydrogen production cost in industrial centers is 310YenGJ(-1) and the FOB export cost of liquefied hydrogen to 10 000 km away, to Japan for example, is 1523 Yen GJ(-1).
