Hydrogen Storage | Tanks, Materials, Technology, Methods
The issues of hydrogen storage run through the hydrogen production, hydrogen transport, supply and demand for end use of hydrogen as an energy sources. Mobile applications drive the development of security, space saving and cost-effectiveness of hydrogen storage and other applications benefit significantly from technological improvements in vehicle storage systems.
At the moment, hydrogen can be collected in a liquid or gas or chemicals. The most common and matured method to store hydrogen is trough compressed gas to hydrogen. This is because liquid hydrogen takes up less space but requires cryogenic tanks. It resulted in very low energy density of compressed hydrogen in 5000 with 10000 psi funding is needed to improve the range of vehicles. Moreover, the liquefaction of hydrogen is an energy intensive process.
In recent years, the alternative method of hydrogen storage devices with metal hydrides or carbon nanotubes has shown promise. Hydrogen can be released when needed, from these materials under certain temperature and pressure. There are also chemical binding hydrides for hydrogen research in a compound, then the release of hydrogen catalyzed by a chemical process. However, these new methods are now expensive.
At the moment there is no technology that meets all the criteria which includes: best storage, low cost, low weight, small volume, secure, easy to use, saving long-term sustainability, high performance storage.
Hydrogen Storage Barriers
Current research and development efforts to get the best available hydrogen storages are inadequate. A wide research and investment in developing hydrogen storage technologies will be necessary to achieve performance and cost for a low cost and mass production acceptable to the hydrogen storage.
Weak demand in producing hydrogen storage devices means high cost. Since there are few hydrogen powered vehicles on the market at the moment, more mature technologies, compressed and liquid hydrogen storage is quite expensive. The initial low rate, the hydrogen end-use applications (mainly imported) vehicles is a challenge for the marketing and the cost of hydrogen storage technologies for today.
Hydrogen Storage Strategies
The development of a coordinated national program to get a go in producing advance materials for hydrogen storage is needed. A national program funded by the state and company is necessary to improve performance and reduce costs for the storage of hydrogen. Special needs new material for chemical hydrides, and semiconductors for storage of hydrogen. It will be removed from the storage of Research and Development at a level commensurate with its importance. While storage technologies are part of the hydrogen economy a success, research and development should be increased in this area in order to match the efforts of Research and Development and other areas of the development of hydrogen.
Hydrogen Storage Devices
Under current research, there are some choices of relatively lightweight, low-cost devices and low-volume hydrogen storage to cover a variety of energy requirement. Pocket tanks of hydrogen will be popular to power in mobile telephony and computer equipment. Metal hydrides is suitable to power in solid-state storage media that is in mass production at the moment. The storage devices should be developed based on the structures of carbon.
There is a need in particularly the mass production of hydrogen storage media. At the moment, there is no market for the driving force behind efforts to reduce the cost of raw materials and the development process of effective mass production. Still the most advanced compression technology and storage of liquid hydrogen is costly because of lack of demand. When the research of hydrogen storage technologies and optimized hydrogen process is gain maturity in the laboratory, storage systems are the next step would be to integrate practices developed and demonstrated of hydrogen storage.
Lack of storage devices that can be easily, access, and marketed at competitive prices and hydrogen fuel cells, are the main factors that interfering with the application of hydrogen as an energy source. Develop a hydrogen economy, consumers will have easy access to cells, and storage devices are a key. Improved hydrogen storage provides easy access to vehicles to hydrogen production methodes facilities distributed or centralized power station.
