“…7 The relevance of hydrogen as an energy carrier is attributed to its unique properties of being convenient, safe, versatile, 8,9 easy to produce from renewable energy systems, and its ability to be converted to a desirable form of energy. 10,11 In addition, hydrogen has become a favorite energy carrier as it has a very high calorimetric value, with a lower heating value of 120 MJ kg À1 compared to petrol, which is approximately a third of this at 43 MJ kg À1 . 12 However, hydrogen energy shows advanced properties and characteristics when compared with other sources of primary energy; the key advantage of hydrogen is that CO 2 is not produced when it is burned.…”

“…Countrywide hydrogen supply chain analysis receives increasing attention from the scientific community [5][6][7][8]. These approaches analyze cost-effective hydrogen delivery methods, including hydrogen pipelines as well as gaseous and liquid hydrogen trailers, whereas hydrogen pipeline transmission shows the highest long-term economic potential for high hydrogen demand [5,8]. Despite the increasing number of pipeline system assessments for hydrogen, to the best knowledge of the authors, there are no detailed countrywide technoeconomic studies of NG pipeline reassignment for hydrogen transport.…”

The uncertain role of the natural gas infrastructure in the decarbonized energy system and the limitations of hydrogen blending raise the question of whether natural gas pipelines can be economically utilized for the transport of hydrogen. To investigate this question, this study derives cost functions for the selected pipeline reassignment methods. By applying geospatial hydrogen supply chain modeling, the technical and economic potential of natural gas pipeline reassignment during a hydrogen market introduction is assessed.The results of this study show a technically viable potential of more than 80% of the analyzed representative German pipeline network. By comparing the derived pipeline cost functions it could be derived that pipeline reassignment can reduce the hydrogen transmission costs by more than 60%. Finally, a countrywide analysis of pipeline availability constraints for the year 2030 shows a cost reduction of the transmission system by 30% in comparison to a newly built hydrogen pipeline system.The technical viability of pipeline reassignment relies on the capability of minimizing material failure due to hydrogen-induced damage and enabling secure hydrogen delivery. Hydrogeninduced material fracturing is caused by hydrogen permeation into the crystalline steel structure, and serves to diminish the material's mechanical properties, which are required for proper pipeline utilization [10]. The underlying hydrogen-induced material fracturing mechanisms of carbon steels are well understood, and is one of the reasons for equipment failure in the oil and gas industry [10,11]. Drawing on the analyses in the literature, this study will focus on the two main mechanisms of pipeline material degradation that most likely result in the premature failure of conventional steel, namely: the degradation of heat-affected zones (HAZ) and fatigue crack propagation (FCP) in the base pipeline material [12]. Degradation of the HAZ occurs due to hydrogen-induced subcritical crack growth under static load in pipeline welds, while the hydrogen-induced FCP rate increase takes place in the base material of the pipeline.The two aforementioned mechanisms have been analyzed in the literature with the result that the use of pipeline steel X70 is found to be a suitable option to eliminate the former, and to partially address the latter degradation mechanism [12][13][14][15][16][17]. Xu investigated the subcritical crack growth of the HAZ in pipeline segments of steel X70 and X42, with his results showing no sign of subcritical crack growth in either type of steel [15]. Similar tests conducted on X70 steel to assess the resistance of these materials to subcritical cracking in 6.9 and 4.1 MPa hydrogen gas partial pressures reported no subcritical crack growth for either type [12].Lastly, Raymond et al. reported that steels with a yield strength ranging from 200 to 580 MPa will not show signs of subcritical crack growth under static loads when exposed to a gaseous hydrogen environment [16]. In the case of steel type X70, the yield stren...

Modeling Hydrogen Refueling Infrastructure to Support Passenger Vehicles †

et al. 2018

The year 2014 marked hydrogen fuel cell electric vehicles (FCEVs) first becoming commercially available in California, where significant investments are being made to promote the adoption of alternative transportation fuels. A refueling infrastructure network that guarantees adequate coverage and expands in line with vehicle sales is required for FCEVs to be successfully adopted by private customers. In this paper, we provide an overview of modelling methodologies used to project hydrogen refueling infrastructure requirements to support FCEV adoption, and we describe, in detail, the National Renewable Energy Laboratory's scenario evaluation and regionalization analysis (SERA) model. As an example, we use SERA to explore two alternative scenarios of FCEV adoption: one in which FCEV deployment is limited to California and several major cities in the United States; and one in which FCEVs reach widespread adoption, becoming a major option as passenger vehicles across the entire country. Such scenarios can provide guidance and insights for efforts required to deploy the infrastructure supporting transition toward different levels of hydrogen use as a transportation fuel for passenger vehicles in the United States.
