Other chemical storage options

Once again the distinction between different t)q)es of chemical hydrogen storage is a bit artificial, as reactions beyond dissociation were already involved in several of the forms described above and notably in the use of hydrides called complex. But generally, any reversible reaction scheme with different amoimts of hydrogen on either side of the equation may be con- 

A number of other chemical reactions have been contemplated for storage applications. Here only a single example shall be mentioned, involving the hydrocarbons decalin and naphthalene. 

Comments on the practical options for use of various types of storage in hydrogen energy carrier systems are given below in section 2.4.6 and, for particular implementations, in Chapter 4 and section 5.1.

Some treatment options, such as the use of stockpile incinerators, would destroy the non-stockpile item directly. Others, especially those involving chemical neutralization, generate liquid secondary waste streams that require further treatment before disposal. This secondary waste treatment could take place in a commercial treatment, storage, and disposal facility (TSDF) or could employ one or more of the individual alternative technologies, such as chemical oxidation, either at the site where chemical neutralization takes place or at an off-site location. If secondary waste is defined as hazardous waste, such treatment would need to be conducted at a commercial TSDF permitted or approved by the appropriate regulatory authority under the Resource Conservation and Recovery Act (RCRA). 

The SRS CMP requires chemical hazards to be examined at every stage in the life cycle of the chemical. The first option is to eliminate the use of a hazardous chemical if possible. Where elimination is not practicable, the minimum amount required for the application is procured. Other areas to be examined include, but are not limited to, the potential impact on safety basis in selection of the warehousing facility, onsite transportation, designation of storage locations within operating facilities, handling and use, and... 

Mixed waste produced at university, hospital, and medical research laboratories is typically a mixture of a low-level radioactive waste and chemically hazardous waste. Mixed waste from nuclear and energy research laboratories can include both low- and high-level (e.g., spent nuclear fuels) radioactive materials combined with chemically hazardous waste. Disposal options for mixed waste are usually very expensive. For many types of mixed waste, there are no management options other than indefinite storage on site, or at an approved facility, in the hope that treatment or disposal options will be created in the near future.
