Advantages And Disadvantages Of Hydrogen Energy Environmental Sciences Essay

Advantages And Disadvantages Of enthalpy Energy Environmental Sciences Essay heat content is a combination of the Greek words Hydro and Genes meaning water and generator. It is the inaugural element in the periodic table. total heat is the main component of water, which c all overs over 60% of the planets surface. 1Hydrogen is the most abundant element in the world, although it also exists as a free bollix up on Earth. Currently enthalpy is produced mainly from fossil dismisss for industrial purposes in petroleum refining, chemical merchandise, metal manufacturing and electronics production.Hydrogen technologies are the technologies will associate with the production put on of atomic number 1. Hydrogen technology is the key to the advancement and improvement of raise cells running on congenital gas for domestic combined heat and source systems and for the distribution of electricity. Hydrogen technologies seat replace incompetent traditional combustion technologies whi ch waste up to 2 / 3 of the furnish used.There are different shipway of making hydrogen in the UK. The most inexpensive way is to convince indispensable gas into hydrogen by a process called reformation. The Reforming of inwrought gas into a hydrogen produces CO2 but no much than burning 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 instantaneously or reforming it into hydrogen.2.2 FUEL CELLA fuel cell integrates hydrogen with oxygen from the air in a chemical reaction, producing electricity. 7 adept of the fuel cell types is for transport, (the proton exchange membrane fuel cell and it consists of deuce electrodes, and it is separated by a membrane. )2.3 UK DEVELOPMENT PATHHydrogen use in the UK start with transport classicularly for fuelling fleet vehicles and buses.U.K. engineering strategy Board (TSB) Awards 9m to Aid Hydrogen Fuel Cell Development acknowledgment Energy technology companies are set to receive 9 one thousand million of funding for travails involving fuel cells and hydrogen technologies, it was announced today (August 28).The presidency 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 fuddles.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 protagonist the French aircraft manufacturer reduce emissions and decrease fuel consumption9Hydrogen fuel cell hybrid buses to name the road in Sunderland10 November 2009 devil 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. home FOR a hydrogen economy IN the UK7An theme is defined as a collection of technologies that are connected unitedly in a specified way and are grouped into the chase five categories sources of energy conversion (including compression) fuel ecstasy storage demand.The expert model of hydrogen bags developed on a nodal network structure.Transporting hydrogen is a very important part of the cost of the transfered product. The design of al-Qaida takes 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 syste m include selection of the site for hydrogen 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 tierce main areas where hydrogen is produced at a commercial scale. These areas are thenor-west 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 stream 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 trade 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 th e 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 local government to assist in this study the great London Authority (GLA), BP, BOC, BMW and Air Products.
