Hydrogen batteries are energy storage systems that utilize hydrogen as a fuel source to generate electricity. According to the U.S. Department of Energy, hydrogen batteries convert chemical energy from hydrogen into electric energy through a process in a fuel cell.
Hydrogen energy is an alternative to fossil fuels that may represent a cleaner way to power our world. Fuel has always powered humankind’s technological advances, from the wood-burning fires first used to cook food to the fossil fuels that propelled the Industrial Revolution and have made modernity possible.
According to the U.S. Department of Energy, hydrogen batteries convert chemical energy from hydrogen into electric energy through a process in a fuel cell. The U.S. Department of Energy explains that hydrogen batteries consist of two electrodes, an electrolyte, and hydrogen gas.
Hydrogen is stored and converted to energy in a battery through a series of steps involving fuel cells. First, hydrogen gas is stored in pressurized tanks or within solid-state materials. This storage method allows for safe and efficient containment of hydrogen. When energy is needed, the hydrogen gas from storage is released into the fuel cell.
Traditional batteries store energy chemically within their materials, while hydrogen batteries generate energy through a chemical reaction between hydrogen and oxygen. Hydrogen batteries, specifically fuel cells, operate by converting hydrogen gas into electricity. Here are the key differences explained in detail:
There are several ways to use hydrogen for energy once it is produced. The most prominent is in fuel cells, which convert the chemical energy stored in hydrogen and oxygen into electricity. Unlike with gasoline-fueled engines, there are no harmful emissions like carbon dioxide.
