Batteries and Hydrogen Storage: Technical Analysis and Commercial Revision to Select the Best Option

This paper aims to analyse two energy storage methods—batteries and hydrogen technologies—that in some cases are treated as complementary technologies, but other ones they considered opposed technologies. A detailed technical description of each technology will allow understand the evolution batteries technologies: looking for higher capacity lower maintenance, while technologies pursuing better volumetric gravimetric densities. Additionally, systems, a mathematical model is required know state charge system. For this purpose, proposed conventional batteries, compressed tanks, liquid metal hydride which makes it possible integrate systems into management strategies that aim solve balance plants based on hybrid systems. From point view, most easier operate do not require special operating conditions, methods currently functioning at extremes (high temperatures complex hydrides low or physisorption). comparison made also includes research trends future possibilities an attempt help plan policies.
