    Global warming and fuel cells

    Can someone tell me how fuel cells help with global warming?

    • No one knows the noisy noisy you make than you, stupid short!!!

    • What makes the Ballard fuel cell so loud?

      thanks

    • "Efficiency is irrelevant with regards to electricity fed into an electrolyzer."

      Huh?

      Higher efficiency means lower cost. Cost is what keeps clean renewable energy from becoming mainstream.

    • maytagman,

      <Can someone tell me how fuel cells help with global warming? >

      Yes....
      No CO2 as and exhaust...among other toxic chemicals.

    • A new study from NASA says climate change is caused by human activities, and that the burning of fossil fuels may be rivaled by land-use policies as a cause of global warming. Farming, irrigation, urban sprawl, deforestation and other changes in the environment may have substantial effects in changing regional climates, which contribute to environmental changes worldwide. The reports says changing land uses in North America, Europe and Southeast Asia are redistributing heat; and one of the report�s authors, Steve Running at the University of Montana, thinks international dialogue about climate change has largely neglected land use and focused on reduction of greenhouse gases. ��We�re not trying to replace Kyoto but instead bring in an additional variable which has been ignored.�� -

    • Fuel Cells are capable of a highly efficient utilization of the chemical energy available from fossil fuels, therefore less fossil fuels are required to meet existing energy demands. Less fossil fuels being used for energy extraction means less CO2 being released to the environment. Ideally, the source for Hydrogen for fuel cells should be water, instead of fossil fuels. However, that requires, for greatest conversion efficiency, that the energy required to split the hydrogen from the water be from alternative energy sources such as wind power, photovoltaic, nuclear, hydroelectric, or any other where fossil fuels are not burned.

      • There's no indication that Fuel Cells are more energy efficient end-to-end than traditional internal combustion engines.

        Assuming that the hydrogen is extracted from kerosene, the process to do so is relatively energy intensive, and the storage of hydrogen is also problematic.

        Extraction of hydrogen from water is extremely energy intensive, and the end-to-end process consumes more power than it produces in the automobile. This power is generated in traditional power plants.

        In short, fuel cells are energy hogs, much like their cousins, batteries.
