Herein, the technological development status and economy of the whole industrial chain for green hydrogen energy “production-storage-transportation-use” are discussed and reviewed.
What is a hydrogen-based chemical energy storage system?
A hydrogen-based chemical energy storage system encompasses hydrogen production, hydrogen storage and transportation, and power production using hydrogen as a fuel input21. (See Exhibit 12.) The application of HESS centers around the energy conversion between hydrogen and other power sources, especially electricity.
What is hydrogen storage & transportation?
Hydrogen storage and transportation is the intermediate link of hydrogen energy industry chain, which is the key to balancing the fluctuation of the industry chain and ensuring the security of supply. Hydrogen is flammable, explosive (explosion limit is 4% to 74.2%) and diffusible, resulting in difficulties in storage and transportation.
Can a hydrogen supply chain make hydrogen a key energy carrier?
To realize a hydrogen economy in the future, it is essential to construct a comprehensive hydrogen supply chain that can make hydrogen a key energy carrier. This paper reviews the various technologies involved in the hydrogen supply chain, encompassing hydrogen production, storage, transportation, and utilization technologies.
Hydrogen energy industry chain mainly includes the hydrogen preparation, storage, transportation and utilization, which involves the integration and technological innovation of many industries.
What technologies are important for a hydrogen supply chain?
This paper reviews the key technologies of hydrogen production, hydrogen storage, hydrogen transportation and delivery, and hydrogen utilization, which are important for the hydrogen supply chain. The challenges of constructing a hydrogen supply chain are also discussed.
Establishing a hydrogen supply chain is fundamental for achieving a hydrogen economy . A hydrogen supply chain should encompass hydrogen production, hydrogen storage, hydrogen transportation and delivery, and hydrogen utilization [18, 19]. The key components of a hydrogen supply chain are illustrated in Figure 2.
