Hydrogen Fuel Of The Future

A fuel cell is, in principle, a very simple electrochemical device. The chemical reaction that powers hydrogen fuel cells is the same as that which occurs when hydrogen burns. The chemical equation for this reaction is: 2H2 + O2 ( 2H2O + energy. "Normally hydrogen burns, reacting with oxygen from the air, producing water, heat and light. ... In the fuel cell the chemical reaction is exactly the same, but instead of producing light and heat energy, electrical energy is produced."2 All fuel cells consist of an electrolyte (a substance that allows only the passage of ions) sandwiched between two electrodes. When a fuel containing hydrogen is passed over the negative electrode, otherwise known as an anode, it is ionized. Ionization of the fuel, often accomplished with the assistance of a catalyst, removes electrons from the hydrogen creating positively charged hydrogen ions and negatively charged free electrons. Since only the ions can pass through the electrolyte situated between the electrodes, the electrons must find another route to the positive electrode or cathode, where they will be reunited with the hydrogen ions and combined with oxygen atoms to form water. The electrons passing around the electrolyte constitute an electric current, and thus can be used to provide power during their journey from anode to cathode.3

Fossil fuels and other power generates are slowly changing the world. Alternative power sources are slowly becoming more popular in everyday life while the technology progresses. Using these power sources that don’t pollute the atmosphere could be the change in the world that completely changes the way the world uses energy. Engineers and technicians have been producing these alternative ways for years and years. A few, but not limited to consist of: Solar panels, Wind turbines, Wave tech and much more.

Though humanity still has developed industrial systems, there have been laws and social norms put in place to protect the environment. Odum discusses fuel-powered systems in industrial areas, “they require so much energy and create so much waste heat and pollution, that they have an enormous impact on the other two environments.” In 1993, this was true since the primary use of energy was coal, oil, natural gas, all carbon emitting energy sources. However, countries like China, Germany, the United States have reduced the emission coming from these fuel-powered systems in the past 25 years. There are now other options for environmentally clean power, people are recycling their trash, using less water, and cutting back energy usage.

Hydrogen has a huge role on American Culture. Discovered by Henry Cavendish, it has made no negative impacts on the environment. It has an atomic number of 1 and it was discovered in the year 1766. The electron configuration of Hydrogen it 1s1 with a boiling point of -423.2 F. At room temperature its state is gaseous. Hydrogen has 3 common isotopes, which are protium, deuterium, and tritium.

Hydrogen fuel cell vehicles (fcvs) have not been around for long, but over the past decade that have developed into a new potential successor of the combustion engine. Fcvs function the same as an electric cars but the difference is the hydrogen fuel cell stack. Hydrogen fuel stacks are just multiple layers of fuel cells stacked up and when hydrogen is pumped in to mix with oxygen a reaction takes place. From this reaction electricity and water vapor is created. The electricity carries on and powers the electric motor(s) in the car. The vapor is released from the exhaust and since only water vapor is released, no harm is done to the environment.

Every element is valuable and unique due to the endless arrangements of sub-atomic particles, which fascinates me. This allows for a diversity of elemental properties, sparking innovation for chemists to develop new products from different tasting chocolates to materials used for rockets- shaping society and the environment of the modern world. The sheer range of applications where chemistry is involved inspires me to contribute, while learning, unlocking why everything behaves the way it does.

Hydrogen was first found in later 16th century but it was not confirmed as a kind of chemical element by Henry Cavendish before 1766. It is a chemical element with symbol H and atomic number 1. That means it is the first one on the periodic table and each atom just has one proton and one electron.And with a standard atomic weight of 1.008, hydrogen is the lightest element on the periodic table. In addition ,it is the most abundant chemical substance in the Universe, constituting roughly 75% of all baryonic mass. On Earth,most of hydrogen exists in molecular forms such as water or organic compounds

Some of the concerns regarding hydrogen that are currently limiting its widespread throughout the world is hydrogen gas is very time consumer which requires a lot of time to free up from its elements even though it is less expensive than regular gas. Hydrogen gas cannot be moved through pipelines like oil due to it is a very light gas. Hydrogen gas require energy such as oil, coal, and natural gas to separate it from oxygen which will not just have logistical issues but also environmental issues.

Imagine never being locked out of your disgusting gas-guzzling vehicle in sub-zero temperatures pumping your car full of toxic chemicals and then later emptying your bank account to pay for the environment killer ever again. This reality is near and approaching faster than ever before. Although, it is not completely beneficial. It is evident that at an international level, electric cars are needed. But, this is only one side of the story, despite common belief, electric vehicles are not always good for the environment. It is true that they will benefit bank accounts, however, the only way for electric cars to improve the environment is if they are powered by clean renewable energy.

With proper handling, hydrogen is as safe as any other fuels such as gasoline, diesel or natural gas – and in some instances even safer. For decades, codes and standard of handling hydrogen have been implemented and safe system designs have been developed. Now hydrogen is produced, shipped, distributed and used safely worldwide for the use in everything from welding to hydrogenated peanut butter. Over 50 million tonnes of hydrogen are produced annually worldwide. Hydrogen is the most common element in the universe, and it’s also the lightest. This means that if there is a leak in a storage tank, the hydrogen rises and diffuses quickly into non-flammable

Honda has already produced a hydrogen fuel cell concept car they claim is “overall 64% energy efficient”. To put this into perspective in the average gasoline combustion engine “only about 20 percent of the thermal-energy content of the gasoline is converted into mechanical work”, making it 20% energy efficient [5]. This new line of cars could bring about jobs in the automotive industry and all industries that branch from it. As of right now the commercial market for hydrogen gas produced from the use of fossil fuels is at about $100 billion. A majority of this hydrogen goes into producing fertilizers and petrochemicals [1]. All it would take is an inexpensive source of green hydrogen, such as the one recently discovered, to completely change this industry.Overall hydrogen has the ability to bring about jobs and continued advancements in every market and industry touched by it. This could be just about every industry when considering how important transportation and shipping are to the economy; hydrogen would give them an inexpensive fuel for transport. Hydrogen fuel could do this all the while solving our most important problem of finding a renewable energy source.

small, positively-charged proton with a negatively-charged electron orbiting very fast, a model analogous to the earth orbiting the sun, or the moon orbiting the earth. Fuel cells take advantage of this structure. Using a membrane and a catalyst, hydrogen is broken up into a proton and an electron. While there are many different membrane models for fuel cells, the most appropriate one for car travel is the Polymer Electrolyte Membrane (PEM, also called the Proton Exchange Membrane). It is called this because protons are able to easily pass through the membrane. However, because the membrane does not allow electrons to pass through it, the electrons take a detour through an electrical circuit to the other side of the cell. If hydrogen is supplied into the cell at a steady rate, the stream of electrons in the electrical circuit creates electric power. However, like all batteries, you need a positive end (cathode) and a negative end (anode); in other words, the hydrogen atoms must have a “reason” to make this electrical circuit. And what is this reason? Oxygen. With oxygen at the other end, hydrogen is more than willing to create this current so that it can bind and form H2O, or water on the other end.

For years man has relied on energy in order to be successful in life. The industrial revolution relied on coal for the new inventions brought into the world. Life as has never been the same since then. However since that time, there has been little done to improve on energy efficiency and humans still primarily rely on fossil fuels for energy. For over a hundred years the Earth has become more polluted and dirtier than ever before. Now, with new, innovative technology there is an opportunity to change that and to rely on renewable, cleaner sources of energy. The main source of energy for the world should be alternative energy instead of energy from fossil fuels.

In order to understand the why behind the need to change from fossil fuels to hydrogen power, it is necessary to understand what that power is and how it works. Hydrogen is the most abundant and simplest element on earth. It is most commonly found as part of water. In its pure gaseous form it is extremely light, but when ignited in this state releases a large amount of energy in an explosion. In this violent reaction the hydrogen combines with free oxygen molecules in the atmosphere and creates water vapor. This is similar to the way gasoline is combined with air and ignited in an internal combustion engine in the cars used today and like with gasoline, the combustion of hydrogen has risks. In addition to the risk, some of the energy released in the reaction is lost in the form of sound and heat. As an alternative to burning, these same gases can be combined with the use of catalysts to extract the free electrons produced as liquid water is formed(Popovici and Hoble Dorel). Using cables connected to a fuel cell such as this, those electrons go through a circuit, generating electricity. This is more efficient than combustion because less energy is wasted in the form of sound and heat. Going further, greater efficiency for this reaction can be had the lower the temperature it is allowed to take place at, with 83% power at 25◦C(77◦ F)(Popovici and Hoble Dorel). As fuel cells are created with better heat management and

Enel Green Power contributes substantially to the field of environmental and economic sustainability.
