A nickel–hydrogen battery (NiH 2 or Ni–H 2) is a rechargeable electrochemical power source based on nickel and hydrogen. [5] It differs from a nickel–metal hydride (NiMH) battery by the use of hydrogen in gaseous form, stored in a pressurized cell at up to 1200 psi (82.7 bar ) pressure. [ 6 ]
Hydrogen battery may refer to: Nickel–hydrogen battery , a rechargeable battery with a power source based on nickel and hydrogen Hydrogen fuel cell , an electrochemical cell that uses hydrogen as a fuel source
The nickel–hydrogen battery was used for the first time in 1977 aboard the U.S. Navy's Navigation technology satellite-2 (NTS-2). [85] The International Space Station , [ 86 ] Mars Odyssey [ 87 ] and the Mars Global Surveyor [ 88 ] are equipped with nickel-hydrogen batteries.
Hummer H2 & Hummer H2 SUT The GMC Hummer EV (badged as H EV ) is a line of battery electric heavy-duty vehicles produced by General Motors since 2021, and sold under the GMC marque. [ 12 ] The Hummer EV is offered in two variants: a pickup truck and a sport utility vehicle (SUV), unveiled in October 2020 and April 2021 respectively.
Hydrogen gas is produced by several industrial methods. [1] Nearly all of the world's current supply of hydrogen is created from fossil fuels. [2] [3]: 1 Most hydrogen is gray hydrogen made through steam methane reforming.
A hydrogen–bromine battery is a rechargeable flow battery in which hydrogen bromide (HBr) serves as the system’s electrolyte.During the charge cycle, as power flows into the stack, H 2 is generated and stored in a separate tank, the other product of the chemical reaction is HBr 3 which accumulates in the electrolyte.

For a battery, this system includes the charger as well as the battery itself. For the fuel cell this system would include the cell, the necessary fuel and peripheral attachments. Taking the full system into consideration, fuel cells have been shown to provide 530 Wh/kg compared to 44 Wh/kg for lithium-ion batteries. [ 177 ]
