Challenges towards Hydrogen Economy in China
International Journal of Hydrogen Energy, 2020Co-Authors: Lichun Dong, Di Xu, Baoshan HuAbstract:Abstract The increasingly serious energy crisis and environmental pollution caused by the excessive use of fossil fuels have been prompting China to aggressively seek a clean and self-sufficient energy source in the future. In the past decades, Hydrogen has emerged as a promising alternative due to its advantages of cleanliness, abundance, high energy density, and high conversion efficiency. However, several challenges have to be overcome for China's successful transition to Hydrogen Economy. In this paper, the Hydrogen supply chain is firstly described to help the readers to clearly understand the Hydrogen Economy. Subsequently, the feasibility of Hydrogen Economy is discussed by reviewing viewpoints from the literature. Finally, the challenges of China's transition to Hydrogen Economy are detailed summarized and discussed, and the strategies for China to develop Hydrogen Economy were compared with that of Japan and Australia.

Hydrogen Economy - The Role of Hydrogen Energy
Hydrogen Economy, 2017Co-Authors: Hanwei Liang, Lichun DongAbstract:The objective of this chapter is to analyze the internal and external environment of Hydrogen Economy in China using Strengths–Weaknesses–Opportunities–Threats analytical method and then to prioritize the strategies for promoting the development of Hydrogen Economy in China. After the key strengths, weaknesses, opportunities, and threats of the Hydrogen Economy in China were identified and nine effective strategies were proposed, a multicriteria decision-making method by integrating goal programing and fuzzy theory has been developed for prioritizing these strategies, which can help the stakeholders/decision-makers to implement these strategies appropriately. The proposed method is not limited to China, and it is a generic method that can also be used to study the Hydrogen Economy of other regions.

role prioritization of Hydrogen production technologies for promoting Hydrogen Economy in the current state of china
Renewable & Sustainable Energy Reviews, 2015Co-Authors: Lichun Dong, Antonio Scipioni, Anna MazziAbstract:Hydrogen production technologies play an important role in the Hydrogen Economy of China. However, the roles of different technologies played in promoting the development of Hydrogen Economy are different. The role prioritization of various Hydrogen production technologies is of vital importance for the stakeholders/decision-makers to plan the development of Hydrogen Economy in China and to allocate the finite RD then, a fuzzy group decision-making method by incorporating fuzzy AHP and fuzzy TOPSIS was proposed to prioritize the roles of different technologies. The proposed method is capable of allowing multiple groups of stakeholders/decision-makers to participate in the decision-making and addressing problems with uncertainty and imprecise information. The prioritization results by using the proposed method demonstrated that the technologies of coal gasification with CO2 capture and storage and hydropower-based water electrolysis were regarded as the two most important Hydrogen production pathways for promoting the development of Hydrogen Economy in China among the five assessed technologies.

analysis of ontario s Hydrogen Economy demands from Hydrogen fuel cell vehicles
International Journal of Hydrogen Energy, 2012Co-Authors: Ali Almansoori, Michael Fowler, Ali ElkamelAbstract:Abstract The ‘Hydrogen Economy’ is a proposed system where Hydrogen is produced from carbon dioxide free energy sources and is used as an alternative fuel for transportation. The utilization of Hydrogen to power fuel cell vehicles (FCVs) can significantly decrease air pollutants and greenhouse gases emission from the transportation sector. In order to build the future Hydrogen Economy, there must be a significant development in the Hydrogen infrastructure, and huge investments will be needed for the development of Hydrogen production, storage, and distribution technologies. This paper focuses on the analysis of Hydrogen demand from Hydrogen FCVs in Ontario, Canada, and the related cost of Hydrogen. Three potential Hydrogen demand scenarios over a long period of time were projected to estimate Hydrogen FCVs market penetration, and the costs associated with the Hydrogen production, storage and distribution were also calculated. A sensitivity analysis was implemented to investigate the uncertainties of some parameters on the design of the future Hydrogen infrastructure. It was found that the cost of Hydrogen is very sensitive to electricity price, but other factors such as water price, energy efficiency of electrolysis, and plant life have insignificant impact on the total cost of Hydrogen produced.

Hydrogen Economy transition in ontario canada considering the electricity grid constraints
International Journal of Hydrogen Energy, 2009Co-Authors: Amirhossein Hajimiragha, Michael Fowler, Claudio A CanizaresAbstract:Abstract This paper investigates the feasibility of electrolytic Hydrogen production for the transport sector during off-peak periods in Ontario. This analysis is based on the existing electricity system infrastructure and its planned future development up to 2025. First, a simplified but realistic zonal based model for Ontario's electricity transmission network is developed. Then, based on Ontario's Integrated Power System Plan (IPSP), a zonal pattern of generation capacity procurement in Ontario from 2008 to 2025 is proposed, specifying the total effective generation capacity in each zone that contributes to base-load energy. Finally, an optimization model is developed to find the optimal size of Hydrogen production plants to be developed in different zones, as well as optimal Hydrogen transportation routes to achieve a feasible Hydrogen Economy penetration in Ontario up to 2025. The proposed model is shown to be an effective planning tool for electrolysis based Hydrogen Economy studies. The results of the present study demonstrate that the present and projected electricity grid in Ontario can be optimally exploited for Hydrogen production, achieving 1.2–2.8% levels of Hydrogen Economy penetration by 2025 without any additional grid or power generation investments beyond those currently planned.

Hydrogen Economy for a sustainable development state of the art and technological perspectives
Journal of Power Sources, 2001Co-Authors: Mario Conte, A Iacobazzi, Marina Ronchetti, Raffaele VelloneAbstract:Sustainable energy is becoming of increasing concern world-wide. The rapid growth of global climate changes along with the fear of energy supply shortage is creating a large consensus about the potential benefits of a Hydrogen Economy coming from renewable energy sources. The interesting perspectives are over-shadowed by uncertainties about the development of key technologies, such as renewable energy sources, advanced production processes, fuel cells, metal hydrides, nanostructures, standards and codes, and so on. The availability of critical technologies can create a base for the start of the Hydrogen Economy, as a fuel and energy carrier alternative to the current fossil resources. This paper will explore the rationale for such a revolution in the energy sector, will describe the state-of-the-art of major related technologies (fuel cell, storage systems, fuel cell vehicles) and current niche applications, and will sketch scientific and technological challenges and recommendations for research and development (R&D) initiatives to accelerate the pace for the widespread introduction of a Hydrogen Economy.
