  2. Fuel cell - Wikipedia

    en.wikipedia.org/wiki/Fuel_cell

    In the case of fuel cells, useful output energy is measured in electrical energy produced by the system. Input energy is the energy stored in the fuel. According to the U.S. Department of Energy, fuel cells are generally between 40 and 60% energy efficient. [65] This is higher than some other systems for energy generation.

    The Hydrogen Expedition is currently working to create a hydrogen fuel cell-powered ship and using it to circumnavigate the globe, as a way to demonstrate the capability of hydrogen fuel cells. [133] In August 2021 the UK Government claimed it was the first to have a Hydrogen Strategy and produced a document. [134]

    The fuel cell has a high efficiency peak at low load, while at high load the efficiency drops. The hydrogen combustion engine has a peak at high load and can achieve similar efficiency levels as a hydrogen fuel cell. [34] From this, one can deduce that hydrogen combustion engines are a match in terms of efficiency for fuel cells for heavy duty ...

    The Honda FCX, along with the Toyota FCHV, is the world's first government-certified commercial hydrogen fuel cell vehicle. [5] [4] 2008 Honda FCX Clarity. Honda established the world's first fuel cell vehicle dealer network in 2008, and at the time was the only company able to lease hydrogen fuel cell vehicles to private customers.

  7. Hydrogen production - Wikipedia

    en.wikipedia.org/wiki/Hydrogen_production

    Hydrogen may be used in fuel cells for local electricity generation or potentially as a transportation fuel. Hydrogen is produced as a by-product of industrial chlorine production by electrolysis. Although requiring expensive technologies, hydrogen can be cooled, compressed and purified for use in other processes on site or sold to a customer ...
