What if, the universe’s most abundant element, hydrogen, was the fuel for our cars? Using hydrogen energy, or hydrogen fuel, would be great for solving global warming and reducing the amount of greenhouse gas emission produced because it is a really clean energy source, there is a magnificent amount of hydrogen energy, and it’s more efficient than most energy sources. There are some disadvantages for hydrogen energy though. Hydrogen energy is expensive, transporting hydrogen is challenging, and there aren’t many hydrogen fuel stations around for refueling. Hydrogen is the simplest element in the universe, with one proton and one electron.
Moreover, in terms of energy, hybrid cars have higher efficiency compared to conventional and full electric cars as it uses kinetic energy from braking to form electric energy then, charging the battery simultaneously. The engine downsizing applied in hybrid cars produce a lighten car with more power and smaller engine capacity. This had reduced the amount of heat loss to the surrounding hence increase it efficiency. Last but not least, hybrids propose lower service and maintenance cost. Fewer number of parts assembled in hybrids will reduce the consumer spending in service and
What Are the Pros and Cons of Hydrogen Fuel Cells? Hydrogen fuel cells are among the cleanest energy sources today, and they are increasingly used by many people to power up their vehicles. Actually, they now serve as an alternative fuel to automobile technology, converting hydrogen into electricity to charge the batteries. Other than those using hydrogen, there are even other categories, including phosphoric acid (PACF), molten carbonate (MCFC), proton exchange membrane (PEM), alkaline fuel cells (AFC) and solid oxide cells (SOFC). With a focus on just hydrogen fuel cells, the technology certainly comes with many benefits.
In contrast, nuclear fusion also has some advantages like providing an ecofriendly fuel source through the use fusion reactors. Fusion reactors aim to exploit the energy produced by nuclear fusion in the form of heat. They then utilize this heat to operate steam powered generators that produce massive amounts of electricity. This creates a fuel source that produces no air pollution, less nuclear waste than other sources such as gasoline or fossil fuels, and is in great abundance. Fusion is also used in some of the rockets that spaceships used lift off the
“Nuclear power will help provide the electricity that our growing economy needs without increasing emissions. This is truly an environmentally responsible source of energy.” Michael Burgess Prior to the introduction of nuclear energy, fossil fuel was thought to be the only available source in producing energy. Although fossil fuel, such as coal, petroleum, and natural gas, contains high energy value, it produces too many harmful byproducts that ultimately pollute our environment. With the rising concerns over global warming as more and more greenhouse gases accumulate in our Earth’s atmosphere, many voice such opinions that new alternative, yet sustainable method must be adopted to produce energy. Nuclear energy is one of the several alternative energy sources that have been introduced ever since.
This is evident in Figure … where an equivalent amount of energy is given, the nuclear energy is able to sustain power up to years, where normal fossil fuel can only sustain up to a few days. Although there are debates that the life span of nuclear power sources such as Uranium is low and is comparable to oil, this do not pose a threat as nuclear energy can be recycled. In addition, nuclear power plant only emits hot water into the environment which makes it environmental friendly. In fact, little or almost no carbon dioxide is being released into the atmosphere. The little amount of carbon dioxide is produced because of the mining and construction of the power plant, however the amount released is not comparable to that of other fossil fuel.
To diagnosing SUSTAINABLE ENERGY SYSTEM and creating it is two of the most critical issues for any modern society. Now ideally the system of current energy which is based on the fossils fuels and have a negative impact on the environment and the have a limited supply is replaced by the system which is based on the renewable fuel. Hydrogen address the issue of sustainability, environmental emissions like releasing of greenhouse gases in our environment and energy security. Hydrogen is consider most suitable element to replace fossils fuels because it the only element which is found in the abundance in the universe and it burns clean without releasing any greenhouse effect and it is only producing water and has the highest density per unit mass. However, as like FOSSILS FUELS hydrogen is not a primary source of energy , it is an energy carrier.
Nuclear energy is a clean, safe, reliable and competitive energy source. Currently it is seen as the only source of energy to replace other part of fossil fuels which harm the environment and emits large amount of greenhouse gases. Almost no carbon dioxide, and sulfur dioxide or nitrogen oxides are produced in nuclear plants. Nuclear power should be deployed to replace coal, oil and gas in the industrial countries. In the future, nuclear electric power plants will also provide power for electric vehicles for cleaner transportation.
Another chemical, Hydrofluorocarbons (HFCs), having no chlorine atoms which does not bring harm to the ozone layer is considered the best alternative since they are not flammable, such as CF3CH2F,1,1,12 tetrafluoroethane. As CFCs are replaced by HFCs, the remaining CFCS will reduce as the ozone recovers
It gets energy from an electric grid. Since electric vehicles do not require burning fuel, therefore, tailpipe emission is nonexistent. These are the reasons why people like to buy the hybrid and electric vehicles as an environmentally friendly transportation. However, consumers do not realize the resources the automobile manufacturers to produce the hybrid and electric automobiles and how the lithium-ion battery creates a bad effect on the environment. All these positive aspects are shielding the truth.
Finally, fracking does not create as many jobs as other jobs, and natural gas was supposed to be used as a transition fuel between conventional fossil fuels and eco-friendly options, like solar. Fracking is a risky process where the cons outweigh the pros.
