“…Utilizing storage in their model Ishimoto et al [25] indicated that hydrogen storage utilizing electrolysis from renewables could play a role in underpinning the future electricity supply through the deployment of approximately 65% efficient electrolyzers in pursuing 25% emission reductions by 2030, and 50% reductions by 2050 compared to 2005 levels. Li et al [30] posited that 57.5% of curtailed renewable energy in Kyushu could be reutilized via storage, and the effective ratio of gross renewable production could be increased from 59% to 74%.…”

“…Iida and Sakata [34] predicted that direct combustion of hydrogen will play a significant role in supplying energy after 2040 with the increased penetration of renewables causing problems due to power-system interconnection (i.e., the 50 Hz and 60 Hz networks in the East and West of Japan). Direct firing of hydrogen, along with hydrogen gas turbine and hydrogen gas engine combined heat and power (CHP) systems, were found to play a prominent role in the realization of a hydrogen economy [25]. Nagashima [28] highlighted utility-scale power generation from hydrogen as an important indicator of Japan's hydrogen fuel network reaching price maturity and the success of the Basic Hydrogen Strategy.…”

“…They also note that the carbon tax required to achieve comparable emission cuts without hydrogen would be 41.5% higher than the tax implications from hydrogen vehicle deployment. In [25], it is estimated that the 2050 share of light duty FCVs will be approximately 20%, while that of FC trucks will be approximately 57% of the national fleet. In the case of electric vehicles, a direct competitor to hydrogen fuelled vehicles, sales are already quite strong globally, accounting for some 7.2 million vehicles operating globally at the beginning of 2020, with sales accounting for approximately 2.6% of all new global passenger vehicle sales [40].…”

This research qualitatively reviews literature regarding energy system modeling in Japan specific to the future hydrogen economy, leveraging quantitative model outcomes to establish the potential future deployment of hydrogen in Japan. The analysis focuses on the four key sectors of storage, supplementing the gas grid, power generation, and transportation, detailing the potential range of hydrogen technologies which are expected to penetrate Japanese energy markets up to 2050 and beyond. Alongside key model outcomes, the appropriate policy settings, governance and market mechanisms are described which underpin the potential hydrogen economy future for Japan. We find that transportation, gas grid supplementation, and storage end-uses may emerge in significant quantities due to policies which encourage ambitious implementation targets, investment in technologies and research and development, and the emergence of a future carbon pricing regime. On the other hand, for Japan which will initially be dependent on imported hydrogen, the cost of imports appears critical to the emergence of broad hydrogen usage, particularly in the power generation sector. Further, the consideration of demographics in Japan, recognizing the aging, shrinking population and peoples’ energy use preferences will likely be instrumental in realizing a smooth transition toward a hydrogen economy.

“…Hydrogen energy is much higher in quality than oil and natural gas and [25] is an environmentally friendly energy source, since only water vapor is released into the atmosphere because of hydrogen production [26]. According to multiple studies, countries should give greater importance to the production of hydrogen to provide sustainable energy production [27]. Clearly, it will be beneficial for countries to minimize factors hindering hydrogen investment.…”

This study seeks to find the appropriate strategies necessary to make sustainable and effective hydrogen energy investments. Within this scope, nine different criteria are defined regarding social, managerial, and financial factors. A hesitant, interval-valued, intuitionistic fuzzy (IVIF) decision-making trial and evaluation laboratory (DEMATEL) methodology is considered to calculate the degree of importance of the criteria. Additionally, impact relation maps are also generated to visualize the causality relationship between the factors. The findings indicate that the technical dimension has the greatest importance in comparison to managerial and financial factors. Furthermore, it is also concluded that storage and logistics, research and development, and technological infrastructure are the most significant factors to be considered when defining hydrogen energy investment strategies. Hence, before investing in hydrogen energy, necessary actions should be taken to minimize the storage and logistic costs. Among them, building the production site close to the usage area will contribute significantly to this purpose. In this way, possible losses during the transportation of hydrogen can be minimized. Moreover, it is essential to identify the lowest-cost hydrogen storage method by carrying out the necessary research and development activities, thereby increasing the sustainability and effectiveness of hydrogen energy investment projects.

“…This study evaluates the economic viability of electrified roads in the decarbonization of the Danish transport sector. An explicit inclusion of hydrogen long haul trucks and battery powered trucks appear in more studies, addressing, for instance, energy scenarios for South Africa [51], Japan [53,54] and even globally [52]. Lastly, no studies including electric ferries in energy system models are available.…”

Energy Scenario Analysis for the Nordic Transport Sector: A Critical Review

et al. 2019

View full text Add to dashboard Cite

Experiencing the highest growth in emissions since 1990 and relying mainly on oil, transport is considered the most complicated sector to decarbonize. Lately, the Nordic countries have shown remarkable success in reducing greenhouse gas (GHG) emissions, especially in the power and heat sector. However, when it comes to transportation, the greatest source of Nordic GHG emissions, stronger measures are needed. Relying on a rich and diversified portfolio of renewable sources and expertise, the Nordic countries could benefit from a common mitigation strategy by encompassing a larger variety of solutions and potential synergies. This article reviews studies addressing integrated energy and transport scenario analysis for the Nordic region as a whole. The studies targeted are those applying energy system models, given their extensive adoption in supporting scenario analysis. Most notable of these studies is the “Nordic Energy Technology Perspectives 2016” to which a special focus is dedicated. The article reviews the methodological choices and the research content of the selected literature. Challenges/limitations are identified in light of recent transport research, and categorized as: “transport behavior”, “breakthrough technologies”, “domestic energy resources” and “geographical aggregation and system boundaries”. Lastly, a list of suggestions to tackle the identified gaps is provided based on the existing literature.
