How are fuel cells sustainable?

Fuel cell systems can help achieve sustainability when they operate on hydrogen produced from sustainable energy resources. Such hydrogen fuel cell technologies constitute alternatives to conventional fossil-fuel energy technologies and are more efficient, environmentally benign and sustainable.

What are the advantages of using fuel cells?

The benefits of fuel cells are:

  • Reduced greenhouse gas emissions.
  • High Reliability.
  • Flexibility in installation and operation.
  • Development of renewable energy resources.
  • Reduced demand for foreign oil.
  • Improved environmental quality.

Why is hydrogen fuel cells more efficient?

In fact, a fuel cell coupled with an electric motor is two to three times more efficient than an internal combustion engine running on gasoline. Because hydrogen has a low volumetric energy density, it is stored onboard a vehicle as a compressed gas to achieve the driving range of conventional vehicles.

What is the cheapest way to produce energy?

Natural gas, solar and wind are the cheapest ways to generate electric power, according to a new study released by the University of Texas at Austin’s Energy Institute on Thursday.

Is nuclear energy cheaper than solar?

When it comes to the cost of energy from new power plants, onshore wind and solar are now the cheapest sources—costing less than gas, geothermal, coal, or nuclear. Utility-scale solar arrays are now the least costly option to build and operate.

How much is 1.21 gigawatts?

A gigawatt is equal to one billion watts, and most of us are familiar with a watt. The light bulbs in our homes are typically between 60 and 100 watts. So 1.21 gigawatts would power more than 10 million light bulbs or one fictional flux capacitor in a time-traveling DeLorean.

Is a lightning bolt 1.21 gigawatts?

And while lightning strikes vary in strength, Dr. Brown was right: they can produce 1.21 gigawatts of power. That’s a sobering fact when you consider that lightning is Utah’s second deadliest natural hazard and has been for the last 15 years according to Utah.gov.
