“…The authors envisage that in the short term (2016 -2030), trends and prospects of hydrogen commercialization would be linked to coal-with CCS and SMR-based with CCS hydrogen production systems. Please notice that China has identified coal-based production with CCS as one of its key prospects for hydrogen commercialization in a carbon-constrained world [18]. If fossil fuel prices increase, the pursuit of cost parities in hydrogen production by RE could be hastened, especially if the associated CCS cost is considered.…”

Many posit a distinct role for hydrogen within the purview of a future low-carbon, renewables-based transportation system. However, hydrogen is already established as an important energy resource and industrial product displaying versatility of uses and roles in the energy system. In this work, we develop and present an original Sankey-Diagram-based analytical framework aiming at identifying and characterizing key structural aspects of the real hydrogen economy as it exists today (2004 -2015). We include global hydrogen demand and supply, assorted energy flows, as well as the costs of production and we consider value flows. We suggest that potentially evolutionary trends can be insightfully elucidated via a systems perspective on the existing global hydrogen economy. Perhaps counterintuitively, we build upon suggestions that the best prospects for the evolutionary emergence of a robust hydrogen economy could arise in a world of cheap and abundant oil rather than in a world of oil scarcity and rising fossil fuel prices. Furthermore, in the long term (2050), if global oil supply continues to be ample and environmental pressures intensify, then there will be a need for new and more aggressive energy policies and enhanced pressure for rapid technological innovation including in the domain of hydrogen. The information presented in this paper, however, reminds us of the situation as it applies today. Approximately 96% of global hydrogen is a product of fossil fuel, while 35% is required by the fossil fuel industry for its own purposes. This indirect connection between hydrogen economy and global fossil fuel industry will continue to shape the future of hydrogen economy for decades to come. Currently, over $107 billion/annum is spent globally by the petrochemical industry in producing hydrogen, suggesting the scale as well as the irreducible aspects and inherent synergies associated with the aforementioned connection

“…In practice, seven ammonia production alternatives were comprehensively compared, which could serve as an early reference for the sustainable ammonia economy in the future. To be specific, (a) literature was comprehensively reviewed in order to select the essential criteria, the result was a list of 12 criteria from four dimensions that would be vital to assess the ammonia production systems; (b) the weighting result indicates that in order to improve the overall sustainability of a given system, more efforts should be made for upgrading the exergy efficiency, reducing the greenhouse gas emissions, lowing the capital cost, and making more contributions to the related economic systems; and (c) the final sequence implies that sustainable ammonia could be generated by not only using the renewable hydropower, but also using the conventional coal, which proves the findings reported by Bicer et al (regarding the ammonia systems) and Ren et al (regarding the hydrogen technologies). In theory, an integrated MADM‐based framework was proposed, which acts as a generic yet rigorous decision‐making tool to identify the most sustainable system.…”

The comprehensive evaluation of ammonia production systems is of great significance for improving the sustainability of energy management and food supply. Therefore, an important contribution could be provided by developing a generic decision-making framework for prioritizing multiple ammonia production systems and identifying the best one. In this view, this paper aims to propose an integrated fuzzy MADM (multiattribute decision making) framework combining fuzzy BWM (best-worst method), fuzzy CRITIC (Criteria Importance Through Intercriteria Correlation), and fuzzy GRP (gray relational projection) approaches for the sustainability assessment of ammonia production systems under hybrid information. Comparing with the previous MADM-based frameworks for sustainability assessment, this framework adopts the TFN (triangular fuzzy number) to deal with the hybrid information (ie, crisp numbers, interval values, and fuzzy numbers) that arise from real-world decision-making issues. Accordingly, the weights of criteria can be comprehensively determined by integrating the fuzzy BWM and fuzzy CRITIC, which balance experts' subjective preferences and system's objective properties under uncertainties in the determination of the weights, while the sequence of alternatives can be reliably prioritized by extending the GRP into fuzzy conditions, which escalates the ranking capability under hybrid information via considering the relationships and relative balance among the alternatives' performances regarding the multicriteria. Seven alternative systems were studied by the proposed framework, indicating that ammonia generated from hydropower-electrolysis and coal gasification would be more preferable than the others, by considering 12 criteria from the concerns of technological, environmental, economic, and social-political. Additionally, sensitivity analysis and result comparison were conducted to verify the rationality and feasibility of the framework. This work makes a methodological contribution to the MADM-based sustainability research and serves as a reference for developing the ammonia economy in the future.

“…Clearly, geo-political factors at country, or morelocal, levels will be important, e.g. Naterer et al (2008), Lin et al (2008), Ren et al (2015). The future may evolve piecemeal as solutions are adopted or implemented for individual applications.…”

Pulsed power applied to electrolysis offers a potential method for efficient hydrogen production which has not been comprehensively studied to date. Pulsed and plasma electrolysis are introduced and previous research assessed. Electrolysis use in potential space or aerospace applications is substantially weight and volume sensitive. Pulsed plasma electrolysis is able to far exceed the Faradaic limit on electrolysis at very high surface current densities presenting the opportunity to reduce electrode mass and volume. Pulse generation technology is introduced and challenges inherent in application to electrolysis outlined.
