In a hydrogen economy, hydrogen is expansively being used as a means to store, distribute, and convert energy into other useful forms. Hydrogen is expensive, an efficient energy carrier, is dangerous and has low energy density. Of concern were issues pertaining to the effects of a hydrogen economy. Issues like global warming and sustainability of energy sources were raised. However in place of hydrogen other portable applications have been suggested for example, primary and secondary batteries. To conclude, an electricity economy was suggested, with the advantages, that this economy will be more efficient than the hydrogen economy, it could be likely cheaper, safer and would have few technological hurdles.
