Hybrid Storage

Hybrid storage of hydrogen, where a combination of technologies is applied, such as the storage of hydrogen as slush or as a supercritical fluid, is briefly mentioned. 

Some experimenters have combined battery storage and hydrogen storage to see if there are any advantages to such a hybrid storage method. 

A solar hydrogen system that does not have a hybrid storage system (both batteries and gas storage) or doesn t use BSPMs exclusively, will have no loss of stored energy back into the PV panels. Diodes can be used, but, for this system they are not necessary. 

If you are interested in a hybrid storage system with a battery, you can use a blocking diode and you should definitely fuse the battery, or use MCBs (miniature circuit breakers) to prevent possible problems from a short. 

Waste heat from the fuel cell is used to reverse the reaction and release the fuel. In 2005 GM and Sandia National Laboratories launched a four-year, 10-million program to develop metal hybrid storage systems based on sodium aluminum hybrid. 

Also within the WE-NET project, a metal hydride/LH2 hybrid storage system is proposed, where a hydrogen storage alloy serves as a buffer for a liquid hydrogen storage for the sake of ensuring a stable supply plus it absorbs flash hydrogen and boiloff losses [47],... 

For the use in road vehicles, usually two technologies are used pressure vessek with a maximum pressure of 700 bar and LH2 tanks at 20 K. A third type, hybrid storage, is based on adsorption of hydrogen. These systems are being assessed for... 

The advantage to this type of approach hes in the fact that the solution obtained is theoretically optimal. The process of optimization takes account of the physical constraints on the components however, it may be vety costly in terms of computation time (and therefore often incompatible with the real-time requirement that is usually the rule in a hybrid storage system) and also requires prior knowledge of the profile of the load required over time, in order to be able to deliver an overall optimization. 

The high density hybrid monoliths would thus appear to be well suited to storage applications. However, the data presented here are for hybrid monoliths that are far from optimum as storage carbons. A great deal of development work is required to increase the micropore volume and storage capacity of the monoliths. Some of our preliminary work in this context is discussed subsequently. 

Though sodium-sulfur batteries have been under development for many years, major problems still exists with material stability. It is likely that the first commercial uses of this batteiy will not be for electric vehicles. Sodium-sulfur storage batteries may be more well-suited for hybrid electric vehicles or as part of a distributed energy resources system to provide power ill remote areas or to help meet municipal peak power requirements.
