Fuel cells powered by hydrogen represent the latest technology in the push to reduce fossil fuel consumption and greenhouse gas emission. The internal combustion engine’s design limitations have been pushed to their limits and fuel economy has been maxed out. While a shift in consumer preference to smaller and more fuel efficient automobiles would decrease consumption and emissions, the economic model alone will not prompt such a change. The hydrogen fuel cell’s new technology calls for a radical change in design approaches that will test the automakers that choose to mass-produce this technology. The hydrogen harvesting methods required to power the fuel cells have environmental challenges. Regardless of the challenges, the utility of hydrogen fuel cells as a means of propulsion should be explored and experimented upon.
As the push for more economic and environmentally friendly modes of transportation expands into plug-in hybrids and fully electric vehicles, the sustainability of our electric grid will come under greater scrutiny. According to a report from the Government Accountability Office, 70% of electric power in the United States comes from natural gas and coal (Johnson). Moreover, 50% of the power generated from fossil fuels comes from plants built before the Clean Air Act of 1978 and lack the now required emissions safeguards (Johnson). The source and sustainability of today’s energy sources dominates debate about the environment.
The use of hydrogen as a fuel source dates back to the 19th century when William Robert Grove created the first hydrogen fuel cell in 1839 (Lampton). The “gas voltaic battery” as it was called reversed the electrolysis to produce water from hydrogen and the oxygen in the air. E...

Is Greenhouse Gas Emissions Responsible for the Global Climate Change Essay

- Introduction The aim of this report is to evaluate to what extent anthropogenic greenhouse gas emissions are responsible for recent global climate change (Karl and Trenberth, (2003), and to identify the main uncertainties associated with future climate modelling. These queries are firstly explored by analyzing the effects that natural causes such as solar volcanic eruptions and solar output have had on recent global climate. This is then contrasted by looking at the volumes of greenhouse gases that are anthropogenically emitted and the observed effects of this....   [tags: climate, greenhouse gas, atmosphere]

World 's Largest Greenhouse Gas Emission Footprints Compared Per Capita On Earth

- Australia has one of the world’s largest greenhouse gas emission footprints compared per capita on earth. As of 2006, Australia 's emissions were the highest of any OECD (Organisation for Economic Co-Operation and Development) nation, with 26.7 tonnes per person per year of equivalent carbon dioxide (Garnaut 2008). In comparison, the United States had just 20.6 tonnes per person per year of equivalent carbon dioxide in 2006 (Garnaut 2008). Equivalent carbon dioxide refers to the volume of carbon dioxide required to have the same greenhouse effect as the other greenhouse gases being evaluated....   [tags: Nuclear power, Energy development, Coal]

Fossil Fuel versus Biofuels as a Primary Fuel for Transportation Essay

- Should we then abandon fossil fuel completely and change to a cleaner type of fuel. Fossil fuel has always been the blame on the bad and polluted environment that we have right now. But we still use fossil fuel, or in this paper we call it petroleum, because it is highly efficient to use it for our transportation fuel. The ‘abundant’ reserve and the increasing development of technology to harness it efficiently from beneath us has made us realize that petroleum is the best fuel for our transportation needs....   [tags: petroleum, biodiesel, oil, fuel]

Essay on The Impact of Electric Vehicles on Greenhouse Gas Emissions

- The rising levels of atmospheric greenhouse gases (GHG) caused by the increased use of fossil fuels for energy services—notably transportation, heating, and the generation of electricity—is known to be one of the foremost drivers of climate change. The United States is responsible for one-fourth of the world’s total greenhouse gas emissions, representing only 5% of the world population and it becomes the world’s single largest emitter of atmospheric greenhouse gasses (EPA, 2011) .

Australia’s Annual Greenhouse Gas Emissions Essay

- ... For example, normally power coming from a dirty power station which emits a large amount of pollution will be considered to be equal to a clean power station which is able to produce as much energy despite being smaller. The carbon tax will be variable to this such that products from dirtier sources that cause more pollution will be more expensive than the cleaner ones. This is advantageous in that it lets smaller processes compete on price. In the long term, various companies will seek to reduce the pollution created by their power station to lower their costs....   [tags: carbon tax, alternative sources, coal]

Global Warming and the Greenhouse Effect Essays

- Global Warming is due to the greenhouse effect. The greenhouse effect is a naturally occurring process that aids in heating the Earth's surface and atmosphere. It results from the fact that certain atmospheric gases, such as carbon dioxide, water vapor, and methane, are able to change the energy balance of the planet by being able to absorb longwave radiation from the Earth's surface. Without the greenhouse effect, life on this planet would probably not exist as the average temperature of the Earth would be a chilly -18 degrees Celsius, rather than the present 15 degrees Celsius....   [tags: Greenhouse Effect Climate Change]
