Hempstead, N.Y., Using Wind Turbine to Generate Hydrogen for Fuel Cell Vehicles

December 19, 2011

HEMPSTEAD, NY – The Town of Hampstead is using a wind turbine to power a system that generates hydrogen for the Town’s fuel-cell vehicles. The wind turbine stands 121 feet tall and can generate up to 180 megawatts of power per year, which will be used to power the only hydrogen fueling station on Long Island. The hydrogen fuel is used to power Toyota fuel-cell vehicles operated by the Town and a hydrogen/natural gas-fueled bus.

In terms of annual savings, the Town said it will have to calculate the amount of hydrogen fuel used and generated against hydrogen fuel prices on the open market.

The Town used funding for the turbine from a $4.6-million United States Department of Energy grant secured by the municipality. The turbine cost $615,000, and electrical and marine bulkheading work was performed by Town employees.

Other projects the Town is using for the grant include a solar field, two solar trackers, a solar-powered carport, and a geothermal energy project that will handle heating and cooling at the Town’s Conservation and Waterways facility.

    In the article it is written "The wind turbine stands 121 feet tall and can up to 180 megawatts of power per year".

    Megawatts are not a measure of energy, Megawatts are a rate of energy that can be provided in a given period of time.

    If you think of electricity or energy as a liquid, Megawatts are similar to saying "Gallons per Second".

    To describe the total amount of energy created, you would say Megawatt-Hours which I think is what you were trying to say.

    Similar to liquids,
    (Megawatts) * hours = Total Energy in Megawatt-hours
    (Gallons per hour) * hours = Total liquid in Gallons

    180 Megawatts is way too much power from a single wind turbine,
    but 180 Megawatt-hours over a period of a year sounds reasonable.

    From what I am seeing in Wikipedia, large wind turbines can provide around ~7 Megawatts (think gallons per second).
