Summary/Abstract This paper presents an innovative approach to promote the hydrogen economy based on the two-sided markets theory. In the hydrogen economy, the hydrogen is delivered to the customers and is then converted into electricity and heat by fuel cells. This environmentally friendly decentralized power network consists of fuel cell manufacturers, hydrogen producers, and the purchasers of fuel cells and hydrogen. We present the specific characteristics of networks - two-sided market effects - and describe their effectiveness of establishing a network. Because the coordination of these effects additionally helps to implement the hydrogen economy locally, we consider an intermediary in the network. To fulfil this task we model a Bass diffusion process of fuel cells and hydrogen producers. The simulations indicate that including and coordinating the network effects can accelerate the diffusion of fuel cells and hydrogen supply significantly-fuel cell installations can be doubled in the first 5 years.

Symbolic convergence and the hydrogen economy / Sovacool, Benjamin K; Brossmann, Brent   Journal Article
Sovacool, Benjamin K Journal Article

Publication 2010.
Summary/Abstract This article documents that the hydrogen economy continues to attract significant attention among politicians, the media, and some academics. We believe that an explanation lies in the way that the hydrogen economy fulfills psychological and cultural needs related to a future world where energy is abundant, cheap, and pollution-free, a "fantasy" that manifests itself with the idea that society can continue to operate without limits imposed by population growth and the destruction of the environment. The article begins by explaining its research methodology consisting of two literature reviews, research interviews of energy experts, and the application of symbolic convergence theory, a general communications theory about the construction of rhetorical fantasies. We then identify a host of socio-technical challenges to explain why the creation of a hydrogen economy would present immense (and possibly intractable) obstacles, an argument supplemented by our research interviews. Next, we employ symbolic convergence theory to identify five prevalent fantasy themes and rhetorical visions-independence, patriotism, progress, democratization, and inevitability-in academic and public discussions in favor of the hydrogen economy. We conclude by offering implications for scholarship relating to energy policy more broadly.

System-level energy efficiency is the greatest barrier to devel / Page, Shannon; Krumdieck, Susan   Journal Article

Publication 2009.
Summary/Abstract Current energy research investment policy in New Zealand is based on assumed benefits of transitioning to hydrogen as a transport fuel and as storage for electricity from renewable resources. The hydrogen economy concept, as set out in recent commissioned research investment policy advice documents, includes a range of hydrogen energy supply and consumption chains for transport and residential energy services. The benefits of research and development investments in these advice documents were not fully analyzed by cost or improvements in energy efficiency or green house gas emissions reduction. This paper sets out a straightforward method to quantify the system-level efficiency of these energy chains. The method was applied to transportation and stationary heat and power, with hydrogen generated from wind energy, natural gas and coal. The system-level efficiencies for the hydrogen chains were compared to direct use of conventionally generated electricity, and with internal combustion engines operating on gas- or coal-derived fuel. The hydrogen energy chains were shown to provide little or no system-level efficiency improvement over conventional technology. The current research investment policy is aimed at enabling a hydrogen economy without considering the dramatic loss of efficiency that would result from using this energy carrier.

Which of the technologies for producing hydrogen is the most pr: evaluating the competitive priority of those in near-, mid-, and long-term / Chung, Yanghon; Hong, Sungjun; Kim, Jongwook   Journal Article

Summary/Abstract In order to evaluate the alternative technologies for producing hydrogen in Korea stage by stage, we searched for impact factors, calculated the weights of them and evaluated the hydrogen production technologies in Korea using analytic hierarchy process (AHP) approach. The AHP is a useful method for resolving multi-criteria decision making problems. We investigated 4 criteria (technical characteristics, economic efficiency, marketability, internal capability) and 11 sub-criteria (scale, efficiency, key barriers, carbon dioxide reduction, current production cost, expected production cost in 2017, feed-stock, technical maturity, R&D competitive level, technology gap with competing agencies, and domestic infrastructure). And the alternatives are natural gas reforming technology, coal gasification technology, biomass gasification technology, water electrolysis technology, thermochemical production technology, photoelectrochemical hydrogen production technology, and biological hydrogen production technology. In order to maintain the objectivity of the analysis result and observe the difference among the groups, the questionnaire survey targets were divided into the R&D professional group and policy professional group. This result of study is expected to serve as important basic information in the establishment of a national R&D strategy to prepare for the imminent hydrogen economy era.
