Batteries offer a higher energy density, allowing them to store more energy in a smaller and lighter form compared to hydrogen. This makes batteries the preferred choice for powering devices that need to be compact and efficient.
At Garrett Motion, we generally believe that lighter, smaller vehicles are better candidates for battery electric powertrains, while heavier, larger vehicles are better suited for fuel cells.

Hydrogen will also play a significant role in achieving clean, secure and affordable energy in the future. It is energy-dense, light, storable and does not produce direct emissions of pollutants or greenhouse gasses.
Batteries store and release electrical energy through chemical reactions within the battery cells, while hydrogen fuel cells generate electricity through the reaction of hydrogen
Compact and Lightweight: Hydrogen''s high energy density means that it can store a large amount of energy in a smaller space. This characteristic enables the design of vehicles that are both more compact and
Almost non-existent public hydrogen refuelling stations in Australia: Zero exhaust emissions (besides water), electric-only driving benefits: Most hydrogen today is not eco-friendly in production, true ''green hydrogen'' requires a complex process of carbon capture and intensive use of renewable energy: No contentious large battery required
Hydrogen fuel cells have a far greater energy storage density than lithium-ion batteries, offering a significant range advantage for electric vehicles while also being lighter and occupying less space. Hydrogen-powered vehicles can also be refuelled in just a few minutes, while those that are battery-powered require a wait while the battery
When it comes to energy storage density, hydrogen fuel cells have the upper hand. While one kilogram of hydrogen fuel cells can pack 39.6 kWh, a battery can only store 0.15-0.25 kWh per kilogram. Coupled with the fact that fuel cells are lighter and smaller than high-load lithium-ion batteries translates to greater driving ranges, especially
The biggest difference between the two technologies is that while a battery uses stored energy to produce electricity, a fuel cell does the same by converting hydrogen-rich fuel. The lithium-ion batteries appeared in the markets in the
Batteries store and release electrical energy through chemical reactions within the battery cells, while hydrogen fuel cells generate electricity through the reaction of hydrogen and oxygen. Batteries have higher energy density, longer lifespan, and higher efficiency, whereas hydrogen fuel cells offer quicker refueling times and longer driving
Liquified hydrogen is "many times more energy-dense than even the most exotic battery," Barrett says, and therefore lighter. However, says Barrett, building a future in which airlines fly on hydrogen would be a humongous challenge of engineering—not to mention fantastically expensive. Every airport would need a steady supply of hydrogen
Although both batteries and hydrogen fuel cells are electrochemical devices used as power sources, comparing them is challenging, because they provide power in different ways. Batteries in electric vehicles (EVs) store energy and

Hydrogen fuel cells are also lighter and more compact than high-load lithium ion batteries. Addressing "range anxiety" in the EV market. In an exciting new breakthrough for the industry, lithium ion battery manufacturing giant
Hybrid is the here and now but you can buy a hydrogen-powered Toyota. The Mirai is an electrified car – it has a battery, an electric motor and an inverter, just the same as a BEV – but the energy used to power it comes from the chemical process of its hydrogen fuel bonding with oxygen to generate electricity, which is used to power the car.
The biggest difference between the two technologies is that while a battery uses stored energy to produce electricity, a fuel cell does the same by converting hydrogen-rich fuel. The lithium-ion batteries appeared in the markets in the 1990s and are an
Both battery and hydrogen technologies transform chemically stored energy into electrical energy and vice versa. On average, 80% to 90% of the electricity used to charge the battery can be retrieved during the discharging process. For the combination of electrolyser and fuel cells, approximately 40% to 50% of the electricity used by the electrolyser for hydrogen production
What is the difference between battery and hydrogen as energy sources? Batteries store energy in chemical form, while hydrogen is a fuel that is converted into electricity. Batteries are rechargeable, while hydrogen needs to be refueled. Which energy source is more efficient, battery or hydrogen? In terms of energy conversion efficiency
Dianna researched the energy density of batteries versus hydrogen fuel cells. Energy density is the energy in watts per kilogram of weight. By that factor hydrogen has an energy density of 35,000 watts per kilogram, while lithium-ion batteries have a density of just 200 watts per kilogram.
Indeed, the fuel cell generates electricity from a primary energy source (hydrogen), and the battery stores electricity and needs an external source of electricity to be charged. Hydrogen fuel cells vs. lithium-ion batteries:
Hydrogen-powered cars, or FCEVs (fuel-cell electric vehicles) add a whole new layer to the debate regarding EVs and their impact on their environment

How Hydrogen Cars Work. Hydrogen cars are powered by hydrogen fuel cells, which generate electricity through an electrochemical reaction between hydrogen and oxygen. The electricity produced is used to power an electric motor, which drives the car. The only byproduct of this process is water, making hydrogen cars a zero-emission vehicle.

Hydrogen also has higher energy storage density than lithium ion batteries, both in terms of energy stored per unit weight and energy stored per unit volume. At Garrett Motion, we generally believe that lighter, smaller vehicles are better candidates for battery electric powertrains, while heavier, larger vehicles are better suited for fuel cells.
By that factor hydrogen has an energy density of 35,000 watts per kilogram, while lithium-ion batteries have a density of just 200 watts per kilogram. A wind turbine farm | AFP Photo/Jean-Francois Monier/Getty Images By that measure, hydrogen fuel cells have a big advantage over batteries.
Batteries and hydrogen play a crucial role in creating a cleaner and smarter tomorrow. They are significant because they can both convert electricity into chemical energy and vice versa. They are ready to transform the energy industry, but they differ in their promises and characteristics. That is why batteries and hydrogen stand out as two promising technologies.
