The production of hydrogen from electricity is 60% efficient,
according to Siemens, but the production of electricity from the
hydrogen would also be
about 60% efficient. So the complete round
trip of storing and recovering electrical energy is .6 X .6 efficient.
That would be .36, but the hydrogen to electric conversion is
actually less that 6% efficient, hence the .33 figure.
