Lithium-ion batteries are the dominant electrochemical grid energy storage technology because of their extensive development history in consumer products and electric vehicles. Characteristics such as high energy density, high power, high efficiency, and low self-discharge have made them attractive for many grid applications.
This can be achieved by either traditional internal combustion engines, or by devices called fuel cells. In a fuel cell, hydrogen energy is converted directly into electricity with high efficiency and low power losses. Hydrogen, therefore, is an energy carrier, which is used to move, store, and deliver energy produced from other sources.
