Advantages And Disadvantages Of Hydrogen Energy Environmental Sciences Essay

Advantages And Disadvantages Of Hydrogen Energy Environmental Sciences EssayHydrogen is a junto of the Greek words Hydro and Genes meaning water and generator. It is the first element in the periodic table. Hydrogen is the main component of water, which covers over 60% of the planets surface. 1Hydrogen is the most teeming element in the world, although it overly exists as a free muff on Earth. Currently hydrogen is produced mainly from fossil fuels for industrial purposes in vegetable oil refining, chemical production, metal manufacturing and electronics production.Hydrogen technologies are the technologies will associate with the production use of hydrogen. Hydrogen technology is the learn to the advancement and improvement of fuel cells rill on natural fellate for domestic combined heat and power systems and for the distribution of galvanicity. Hydrogen technologies can replace incompetent traditional combustion technologies which baseless up to 2 / 3 of the fuel used.Th ere are different ways of making hydrogen in the UK. The most inexpensive way is to qualify natural gas into hydrogen by a process called reformation. The Reforming of natural gas into a hydrogen produces CO2 but no more than fire it. However, using the hydrogen in a hydrogen fuel cell or using the natural gas itself in a natural gas fuel cell .The best use from natural gas is to use it as in fuel cells, either directly or reforming it into hydrogen.2.2 FUEL prison cellA fuel cell integrates hydrogen with oxygen from the air in a chemical reaction, producing electric automobileity. 7 One of the fuel cell types is for transport, (the proton exchange tissue layer fuel cell and it consists of two electrodes, and it is separated by a membrane. )2.3 UK DEVELOPMENT PATHHydrogen use in the UK start with transport particularly for fuelling pass by fomites and buses.U.K. Technology Strategy Board (TSB) Awards 9m to Aid Hydrogen Fuel Cell Development Source Energy technology companies ar e set to receive 9 million of funding for projects involving fuel cells and hydrogen technologies, it was announced today (August 28).The politics sponsored Technology Strategy Board (TSB) is to invest the money, along with a further 500,000 from government agency the Engineering and Physical Sciences Research Council (EPSRC), into nine hydrogen fuel cell projects.8Airbus to take off with fuel cell auxiliary power October 9, 2009 by Lisa Sibley, Cleantech GroupUK-based Intelligent Energy says its technology is expected to help the French aircraft manufacturer reduce emissions and decrease fuel consumption9Hydrogen fuel cell hybridization buses to hit the road in Sunderland10 November 2009Two hydrogen fuel cell hybrid buses are set to hit the streets of Sunderland, UK as part of a unique RD program that is bringing Chinese expertise to the region.The UK regional development agency One North East has invested 314000 (US$523000) to sponsor the ECO2Trans hydrogen buses project, which is converting two electric Gulliver U500EUK buses into hydrogen vehicles using a fuel cell, battery and capacitor combination.4The hydrogen fuel cell buses being introducedin London will use an electric motor, with the hydrogen stored in tanks on the roof.3. infrastructure FOR a hydrogen economy IN the UK7An infrastructure is defined as a collection of technologies that are affiliated together in a specified way and are grouped into the following five categories sources of energy conversion (including compression) fuel transportation storage demand.The skilful model of hydrogen infrastructures developed on a nodal network structure.Transporting hydrogen is a very important part of the cost of the transfered product. The design of infrastructure includes the gas pipelines and rail lines for delivering inputs for producing hydrogen that will be an integral part of the delivery system. The main challenges in achieving the best delivery system include selection of the pose for hydro gen production and establishing a possible transportation network.The hydrogen infrastructure in the UK was evaluate current and potential hydrogen production and storage options.The key findings of the research were that there are three main areas where hydrogen is produced at a commercial scale. These areas are theNorthwest of England,Teeside (England)andSouth Wales.The infrastructure scenarios focus on two hydrogen production technologies-steam reforming of natural gas and electrolysis of water-and the different scales at which such plant can be installed.The studyity of hydrogen is produced by teem reformation of natural gas, although a proportion of worldwide hydrogen is produced as a by-product of Ethylene production via cracking. Most Liquid hydrogen is also imported from France, however it is very expensive.In the short to medium term, the available gas production and supply system is incapable of supporting a major expansion of the use of hydrogen in fuel cell .11Hydrogen infrastructure for refuelling London buses.Imperial College London is examining transition strategies for a hydrogen infrastructure for vehicle refueling in London under a project funded by the UK Engineering and Physical Sciences Research Council (EPSRC). Imperial has five project partners from industry and topical anesthetic government to assist in this study the Greater London Authority (GLA), BP, BOC, BMW and Air Products.
