Energy storage is accomplished by producing hydrazine carbonate and later reconverting the hydrazine carbonate to release the energy. Sea water is firstly used in an electrolysis process to prepare hypochlorite. The hypochlorite reacts as a result of introduction of ammonia to produce monochloramine and then hydrazine. The hydrazine reacts as a result of introduction of carbon dioxide to give hydrazine carbonate. To release the energy, the hydrazine carbonate liberates hydrogen or at least a hydrogen-containing gas by reaction over a noble metal-free catalyst. The hydrogen may then be enriched before being fed to a fuel cell.

Method for storing energy in the form of hydrazine carbonate

The invention relates to a method for monitoring the function of a machine element lubricated by a lubricant. The method includes receiving measured values concerning the lubricant, determining a current chemical composition of the lubricant on the basis of the measured values, comparing the current chemical composition with chemical compositions known in advance, which are stored in a database, wherein function failure tendency values for the use of lubricants having the chemical compositions known in advance in connection with machine elements composed of materials known in advance are stored in the database, identifying a function failure tendency value on the basis of the comparison step, and outputting the function failure tendency value.
