Development of renewable energy multi-energy complementary hydrogen energy system (A Case Study in China): A review

Abstract

The hydrogen energy system based on the multi-energy complementary of renewable energy can improve the consumption of renewable energy, reduce the adverse impact on the power grid system, and has the characteristics of green, low carbon, sustainable, etc., which is currently a global research hotspot. Based on the basic principles of hydrogen production technology, this paper introduces the current hydrogen energy system topology, and summarizes the technical advantages of renewable energy complementary hydrogen production and the complementary system energy coordination forms. The problems that have been solved or reached consensus are summarized, and the current status of hydrogen energy system research at home and abroad is introduced in detail. On this basis, the key technologies of multi-energy complementation of hydrogen energy system are elaborated, especially in-depth research and discussion on coordinated control strategies, energy storage and capacity allocation, energy management, and electrolysis water hydrogen production technology. The development trend of the multi-energy complementary system and the hydrogen energy industry chain is also presented, which provides a reference for the development of hydrogen production technology and hydrogen energy utilization of the renewable energy complementary system.

Research and Development Investment and Collaboration Framework for the Hydrogen Economy in South Korea

“…The committees may raise topics of discussion about the directions of the national R&D strategy employing the nationally funded projects-based analytical information. This study can improve the limitations of previous studies [2,4,9,10,18,19,27,29,30,[32][33][34][35][36] in the following ways: the normative statement that governments should endeavor to accelerate the transition into the hydrogen economy can be empowered by the information about the public investment trends of the government, which elucidates the role of government commitment to continuous investment. The other is that the quantitative analyses, based on publications or patents alone, cannot elucidate the scale of funding and technological advancement of hydrogen-economy-related research projects.…”

“…The review of related literature revealed that there are two broad branches for researching the hydrogen economy. One is related to the investigation of the present status of the hydrogen economy and its roadmaps, and it recommends some policies to boost the growth of the hydrogen economy [2,4,5,9,10,18,20,27,29,30].…”

“…The ultimate goal of these plans, or roadmaps, is green hydrogen regarding climate impact. Although these countries have been investing since the last decade, there are still many unresolved issues related to the high cost of producing hydrogen, as well as to its low energy efficiency [18,26,27]. Inevitably, these governments must invest in R&D to achieve reasonable performance and cost targets, as well as generate supply and demand chains for clean hydrogen by developing new infrastructures, reconverting natural-gas pipeline systems, creating new hydrogen markets, and transitioning grey hydrogen industrial sectors toward employing low-carbon hydrogen [4,9,27].…”

“…When electricity that is produced from renewable energy sources is employed in this process, the produced hydrogen becomes a renewable energy carrier, complementary to the applied electricity [9,17]. The hydrogen energy technologies that are based on multienergy systems that correspond to renewable energy, including solar, water, wind, and biomass energies, can improve the energy utilization rate and reduce the cost of hydrogen production and, therefore, represent the future of hydrogen energy [18]. Thus, the Korean government has pursued a green hydrogen economy for economic growth, energy security, and an environment that aligns with domestic demands [19].…”

An optimal schedule model of multi-energy hubs network integrating solar energy

“…Controlling technologies were introduced but there is a lack of research on modelling, optimization, and energy hub application. Similarly, the characteristics of energy system models and existing modelling tools together with challenges in the field of modelling and optimization of the energy systems are also introduced in the studies [6] [7].
