Hydrogen lies in one of the copious replacements for gasoline. It is not an energy source such as oil, but an energy carrier that is produced instead of digging and finding it underground. Though replacing fossil fuels by hydrogen fuel cell is very hard and costs a great deal, for the most part, hydrogen fuel cell is a zero carbon emission fuel which highly reduces the carbon emissions that causes pandemic global warming. Hydrogen is very helpful for nature by cause of replacing fossil fuels with hydrogen fuel cells might end global warming once and for all. Fossil fuels are very limited and they are used a lot. Fossil fuels are also very harmful to nature. Carbon emissions, that are produced from the use of fossil fuels, affects the globe …show more content…
On the other hand, hydrogen has a very limited infrastructure which is considered as a point on the negative side, or you can say one of hydrogen’s cons. And as Kukreja argues about the pros and cons of hydrogen energy; he mentions that “Hydrogen is also hard to move around. Whereas oil can be sent through pipelines, and coal can be carried in the back of dump trucks, super-light hydrogen is hard to transport in a reasonable fashion. It is very expensive to move anything more than small amounts of it, making it impractical for most functions.” [Kukreja] What he said makes sense. Hydrogen is some sort of gas. It’s not a liquid, or solid which can be physically carried in a way or another. Kukreja also mentions that one of the hydrogen energy cons is that it is “Not easy to replace existing infrastructure” [Kukreja] In a common sense, that is logically true. But in reality, if we felt into a problem that is related to global warming. Then the globe would regret building those gasoline stations. Even though it is hard to replace existing infrastructure, it is also necessary to get rid of those infrastructure even if we didn’t have a replacement. But in our position, we actually have a replacement which is hydrogen energy and hydrogen fuel
in 1838. Then in 1932, the first successful fuel cells were engineered by Francis Thomas Bacon
In nature hydrogen is always found combined with other elements, which means it has to be manually made by passing an electric current through water to form hydrogen and oxygen. There is a tremendous amount of energy involved in splitting the molecules to free the hydrogen from its captor. The current method of producing hydrogen from water is through the use of oil and coal. Oil and coal are the two main resources the world is trying to cut back on. The main purpose of using hydrogen is lost when considering the actual manufacturing process of hydrogen contributes a significant amount of carbon dioxide. When the big coal and oil companies start investing their profits in hydrogen, something has gone awry. Each company sees its future limited and wants to ensure their survival. Since they have the most money they will be the main producer of hydrogen. The hydrogen economy will benefit the mining and oil industry at the cost of the clean-energy dream.
The world is dependent on fossil fuels as the prime source of power to meet our energy demands. What are fossil fuels? “Fossil fuels come in three major forms-coal, oil, and natural gas. Because fossil fuels are a finite resource and cannot be replenished once they are extracted and burned, they are not considered renewable.” - (United States Environmental Protection Agency) When the supply of fossil fuels is completely exhausted, what will we rely on to meet our energy needs? An alternative option available that should be implemented more in our use is renewable energy, energy that can be replenished, such as solar, wind, and hydropower. - (United States Environmental Protection Agency) Even though the dependency on fossil fuels is tremendous,
...dition, fossil fuels not only unleash carbon dioxide into the atmosphere, but also is harmful to human when exposed for a long period of time, new energy resources would be needed to replace it such as, wind turbans, biomass energy, wind energy, solar energy, geothermal energy, and hydroelectric energy (Alternative Energy).
The present global economy is nearly entirely dependent on petroleum and crude oil imports from the Middle East. Where the current situation stands now, oil prices will continue to skyrocket and the environmental impact will continue becoming greater if no form of alternative energy is implemented to a greater extent within the coming years. However, to this effect, the industrial cost of producing such forms of alternative energy is in itself primarily composed of coal and petroleum. In this light, I will investigate the practicality of hydrogen fuel cells based upon hydrogen consumption and exploitation. Hydrogen holds enormous promise for the future regarding alternative energy sources. To this point, its ability to be used in cars, weapons, and as miniature batteries has been demonstrated by many companies. However, if this is the case, hydrogen should be the leading supplier of power around the world. What prevents it from being so?
Over the last two centuries, humanity has become increasingly reliant on fossil fuels. Over that time, the consequences of constantly burning fossil fuels have accumulated into a threat to industrialized cities. The burning of fossil fuels causes acid rain to shower on cities and ecosystems around the world, tormenting their inhabitants. The increasingly deadly pollution caused by the burning of fossil fuels has caused the deaths of many people around the world by causing respiratory problems. Not only has the pollution worsened, but the supply of fossil fuels is not limitless – as humanity’s reliance increases the supply decreases, and that is all the more reason to break humanity’s reliance on fossil fuels. Fossil fuels should be replaced with cleaner alternatives because fossil fuels cause environmental hazards, are non-renewable, and are detrimental to human health.
The effects of using fossil fuels are starker than their timelines. Humans release approximately two billion metric tons of pollution annually, mostly from the burning of coal, oil, and natural gas; this pollution is destroying our environment and the ozone layer. Ozone and smog damage forests, crops, and other plant life, and reduces visibility. Other pollutants have the same
Transport exporters are looking for alternative ways to keep human mobility. Gasoline is widely used in motor vehicle. Beside gasoline there is another alternative fuel such as E85, natural gas, compress natural gas, liquid petroleum gas, propane is used as substitute fuel to cut dependence on gasoline. Vehicle makers are putting a billion dollars searching for alternative fuel. Therefore, fuel cells could be a potential candidate for alternative fuel. When considering fuel cell, hydrogen cell is coming in the battlefront. This paper will be explained what is reason behind hydrogen cell to be considered future alternative fuel for the vehicle.
Hydrogen can be produced from a variety of feedstock. These comprises of non-renewable fossil resources, such as coal and natural gas, as well as renewable resources, such as biomass and water with input from renewable energy sources for example sunlight, hydro-power, wind and waves.
Fossil fuels are an important part of life. When you turn on the lights, watch TV, or take a shower, the electricity that you are using is being generated by fossil fuels. The three types of fossil fuels are coal, crude oil, and natural gas. They all take millions of years to form, so they are considered to be “non-renewable”- eventually, the fossil fuels will all be used up. One dangerous biological effect of using fossil fuels is ocean acidification. Extracting and transporting fossil fuels can also be very dangerous. Environmentally damaging accidents such as groundwater contamination, land subsidence, and oil spills occur frequently. Global warming is another possible environmental effect. Fossil fuels have a crucial role in modern society, but since they are non-renewable and dangerous, we should reduce our dependence on them and explore alternative energy sources. Wind energy, hydroelectricity, and solar energy are some examples of renewable fuel sources. There are also many things that people can do everyday to save energy (and, in turn, conserve fossil fuels).
The main components of the hydrogen economy are to use it as a fuel for transport, stationary power and as an energy store. There are a few methods for the generation of hydrogen; this could be from steam reformation, carbon gasification, biofuels or water electrolysis. This replacement for fossil fuels needs a lot more research to be completed before it can match the supply of energy that is needed to power the world. The development of hydrogen to be a major power source needs to be invested in soon due to the unpredictability of when the fossil fuels will run out and the economic grip that some countries have on them.
(123). However fossil fuels are also very bad for the environment as they contain a lot of
Hydrogen is one of the most abundant elements on the earth. It can be found in the oceans as well as the atmosphere. Over the last few years, talk about the future of hydrogen power has grown from a whisper to a roar. The use of hydrogen is not just the burning of the gas, but of its use in a fuel cell. Fuel cells might be the device that causes the extinction of the internal combustion engine. A fuel cell is a device that produces electricity from a fuel and an oxidizer, a substance that combines with the fuel. The fuel and oxidizer react chemically at two separate electrodes to produce the direct electric current; These cells use hydrogen as the fuel and oxygen as the oxidizer. Hydrogen power could be the silver bullet to the current and future energy situation.
Fossil fuels are energy that is in the form of coal, oil, or natural gas that comes from organisms from millions of years ago. The cycle to create fossil fuels takes millions of years to form and is therefore considered a nonrenewable resource of energy. Fossil fuels have been the primary source of energy for man ever since the age of machines, but one of “the main problem[s] with fossil fuels is that there is a limited amount of them” (Problem with Fossil Fuel). As countries become more developed, like the United States, they too will become more thirsty and dependent for fossil fuels. “In 2004, America spent approximately $270 billion to fufill its oil need.” and “90% of all transportation is fueled by oil” (Nakaya 10). With the global rate of fossil fuels going up it is inevitable that they are going to run out, forcing countries to choose an alternative energy source. The other huge problem with dependence on fossil fuels is the effect that the emissions have on the climate. Fossil fuels are made of carbon chains and in order for the reaction...
Fuels like coal, and oil that once were a fine innovation in creating energy are now rapidly deleting and one day will be gone forever; energy that won’t last is often referred to as non-renewable energy. Besides being set up to fail and become inefficient in the future, fossil fuel energy is not clean to use and poses several environmental complications. Coal, for instance is “the dirtiest of all fossil fuels. Coal combustion not only produces sulfur oxides and nitrogen oxides that contribute to acid rain and snow, it generates millions of tons of particulates that cause asthma and other respiratory diseases.” As with all usage of fossil fuels, it creates enormous amounts of carbon dioxide, which contributes to greenhouse gas. Not only are fossil fuels dirty, they also pose as a security risk and unforgiving on the American wallet. (Saini)
