“…Finally, the authors conclude that especially in the heavy-weight transport sector hydrogen is an economic option and can reduce the need for biofuels (Meschede et al, 2018). A similar comparison of an electrified and a hydrogen-based energy system can be found in You and Kim (2020). Here, the case of the South Korean island of Jeju is observed.…”

Globally, more than 740 million people live on islands which are often seen as ideal environments for the development of renewable energy systems. Hereby, they play the role to demonstrate technical solutions as well as political transition pathways of energy systems to reduce greenhouse gas emissions. The growing number of articles on 100% renewable energy systems on islands is analyzed with a focus on technical solutions for transition pathways. Since the first “100% renewable energy systems on islands”‐article in a scientific journal in 2004, 97 articles handling 100% renewable energy systems on small islands were published and are reviewed in this article. In addition, a review on 100% renewable energy systems on bigger island states is added. Results underline that solar PV as well as wind are the main technologies regarding 100% RES on islands. Not only for the use of biomass but for all RES area limitation on islands needs to be taken more seriously, based on full energy system studies and respective area demand. Furthermore, it is shown that there is still not the same common sense in the design approach including and starting at the energy needs as well as on multi‐sectoral approach. The consideration of maritime transport, aviation, cooling demands, and water systems beyond seawater desalination is only poorly considered in existing studies. Future research should also focus on developing pathways to transform the existing conventional infrastructure stepwise into a fully renewable system regarding also the interconnections with the mainland and neighboring islands.

“…An optimal design model of district smart renewable energy systems with electricity, thermal and hydrogen demands is proposed to minimize the total annual cost. Case studies on smart energy systems applied in both urban and rural districts are conducted with a range of levelized cost of energy (LCOE) between 0.43 -0.65 $/kWh [5]. An energy management strategy based on a novel multi-agent system is developed to optimize the cost, grid imported power consumption and power quality of microgrid communities with renewables and electric vehicles.…”

This study develops hybrid renewable energy systems for applications in zero-energy buildings and their community integrated with stationary battery storage and mobile hydrogen vehicles following different cruise schedules. The educational, office and residential building groups in Hong Kong are selected for zeroenergy building case studies based on on-site collected energy consumption data and simulated load data as per local surveys and codes. And a zero-energy community integrating the three building groups is also developed for comparison to evaluate the supply, load cover, storage efficiency, grid integration, system cost and carbon emission indicators. The study results indicate that the renewable energy self-consumption ratio of four zeroenergy scenarios varies between 88.10% -96.01%. The community microgrid performs best in the load cover ratio of 74.96% with shared renewables and storages and achieves positive grid integration performance with a peak-to-average power ratio of 7.65 due to the complementary load characteristics of three building groups. The hydrogen storage efficiency of four zeroenergy building scenarios varies between 37.42% -55.62%. The levelized cost of energy of hybrid systems applied in four zero-energy scenarios varies within 0.48 -0.63 US$/kWh, and it can be reduced to 0.09 -0.24 US$/kWh considering the local feed-in tariff. The CO2 emission of the zero-energy community is about 13631.82 tons, higher than the sum of three buildings by 4.32%, as its power exchange with the utility grid is reduced for more renewable energy self-consumption with higher energy losses. The detailed techno-economicenvironmental feasibility analysis offers valuable references for relevant stakeholders to develop renewables applications in zero-energy building communities of urban areas.

Comparative study of Global, European and Italian Standards on Hydrogen Refueling Stations

et al. 2022

View full text Add to dashboard Cite

The purpose of this paper is to give a strategic overview of the existing standards governing the construction and operation of hydrogen refueling stations. A succinct and comprehensive study of hydrogen refueling station standards globally, in Europe, and in Italy is conducted and discussed in light of the new European Hydrogen Strategy and Roadmap. Among the numerous topics examined, a particular emphasis is placed on the standards in force for on-site hydrogen production via water electrolysis, hydrogen storage, both liquid and gaseous, and refueling protocols for light-duty and heavy-duty vehicles, on an international level through the provision of ISO, IEC, and SAE standards; on a European level through the examination of the CEN/CENELEC database; and on an Italian national level through the analysis of the UNI database.
