A technoeconomic analysis of centralised and distributed processes of ammonia dissociation to hydrogen for fuel cell vehicle applications

Research output: Contribution to journalArticle

Abstract

Ammonia (NH 3 ) has been proposed as a hydrogen (H 2 ) carrier for energy services in the carbon-constrained future. This paper presents a technoeconomic feasibility study of using NH 3 as H 2 carrier for fuel cell vehicles (FCVs) applications. Two cases with different scales of anticipated operations: (1) centralised installation (1000 tonnes day −1 ) and (2) distributed refuelling station (500 kg day −1 ), were considered. Aspen HYSYS v8.6 was utilised to simulate the processes. The H 2 production cost, internal rate of return, payback period and net present value were examined and compared. The results indicate the centralised H 2 production is both technically and economically feasible while distributed H 2 production, falling foul of economy of scale, is not economically viable. The overall H 2 production cost of the centralised H 2 production can reach as low as USD 5.50 kg −1 H 2 accounting for capital expenditure, operating expenses, and decommissioning costs. The sensitivity analysis shown that the overall H 2 production cost is highly sensitive to NH 3 price and moderately affected by utility price and various corporate tax rates considered.
