Green Hydrogen vs Fossil Fuels: Comparing the Future of Energy
Hydrogen is more flexible. Energy can be extracted by either combustion or with a electrochemical means. To call either one "better," we must define the context of what "better" means. That can be with respect to energy efficiency, GHG abatement, or cost, for example. Fossil Fuels vs. Green Hydrogen: Energy Efficiency
Hydrogen and Fuel Cells 101
Key Hydrogen Facts: Can be produced from multiple abundant fuel sources in the U.S. Can be used to store energy and make electricity, with only water as byproduct
Hydrogen vs. Electric Cars: Comparing Innovative Sustainability
Unlike FCEVs, battery-powered electric vehicles are quite energy-efficient. While FCEVs are less than 40% energy-efficient, most battery-powered electric cars and other vehicles boast around 80% efficiency. This means that for every 100 watts of energy produced, nearly 80 watts will be used to power the vehicle.
Energy density
Given the high energy density of gasoline, the exploration of alternative media to store the energy of powering a car, such as hydrogen or battery, is strongly limited by the energy density of the alternative medium. The same mass of lithium-ion storage, for example, would result in a car with only 2% the range of its gasoline counterpart.

That is why batteries and hydrogen play a crucial role in creating a cleaner and smarter tomorrow. They stand out as two significant technologies due to their ability to convert electricity into chemical energy and vice versa. ... The future of energy. Batteries and battery innovations are seeing increasing demand as electricity is being ...
8.3: Electrochemistry
Figure (PageIndex{8}) A hydrogen fuel cell. batteries but require a continuous source of fuel, often hydrogen. They will continue to produce electricity as long as fuel is available. Hydrogen fuel cells have been used to supply power for satellites, space capsules, automobiles, boats, and submarines (Figure (PageIndex{8})).
Visualized: Battery Vs. Hydrogen Fuel Cell | Energy Central
The energy that is stored in the battery can be less easily accessed as the time between uses increases, especially for lithium-ion batteries after they have been used many times. The hydrogen, once it is in the tank, won''t disappear, and if you leave the vehicle for a month without using it, and then try to start it up again, it should work.
