  1. Hydrogen Part 1 of 2 By Ian Mongold

  2. Introduction • Energy Issues • World’s oil supplies are running out • World’s demand for fossil fuels • Degradation of the environment • What does the future hold for alternative green energy sources?

  3. Possible Green Alternative to Fossil Fuels • Hydrogen!

  4. Hydrogen Benefits • Hydrogen is the most abundant element • Less Green House Gas emissions • Only emissions are heat and water • However there are emissions in some production methods • Decrease dependency of foreign oil • Potential to run a fuel cell more efficiently than a internal combustion engine

  5. Hydrogen Challenges • On-board storage • Pressurized tank • Liquid • Material-based storage • Cost (average cost $100,000) • Getting hydrogen to consumers • Public Acceptance

  6. Extraction Methods • Steam Reforming • 95% of Hydrogen • Natural Gas • Splits Natural gas into Hydrogen and Carbon Monoxide • Electrolysis • Electrical current splits water into hydrogen and oxygen • Steam Electrolysis • Uses heat instead of electricity

  7. Breakthrough Extraction Method • VA Tech research team lead by Y.P. Percival Zhang • Large amounts of hydrogen can be extracted from plants • Potentially a low cost environmentally friendly source • Hydrogen specially comes from xylose • His method can use any source of biomass

  8. Benefits of this Method • Utilizes renewable natural resources • Greenhouse gas emissions are very little • This process does not need any heavy metals • Net energy gain of 100% • Uses low temperature waste heat source in the process of make quality hydrogen

  9. Process of Extracting • The researchers created a “enzyme cocktail” • Combine the enzyme with a polyphosphate and the xylose • The large amounts of hydrogen release from the xylose

  10. Process of Extracting (continued) • In the xylose, water molecules split caused by the energy stored • This reaction occurs at low temperatures • The result is high-purity hydrogen that can be used immediately in a proton-exchange membrane fuel cell

  11. Possibilities • This process could be in the market in a couple of year depending on if the technology needed is available. • Market right now for hydrogen produced from natural gas is at around $100billion dollars • If a “Hydrogen Economy” were to occur that number could be $1trillion dollars

  12. Delivery Methods • Pipeline-Owned by hydrogen producers and are limited to small areas • Tube Trailer-Holds up 400kg of hydrogen only practical for short distances • Cryogenic Tanker-Transports hydrogen in a liquid form at -253 degrees C. more economical at long distances but liquefaction process requires large amount of energy

  13. Onboard Storage • Most common is compressed hydrogen tank • Tanks range from 3,600psi to 10,000psi • Most fueling stations have 5,000psi to 10,000psi • BMW is the only car maker to have made a prototype with a cryogenic fuel tank • Therefore hardy any hydrogen stations have liquid hydrogen

  14. Cars Out in the World • Some car manufactures are starting to lease vehicles in Southern California, Japan and Germany • The first hydrogen car to be leased was a Honda FCX Clarity • Other companies like BMW are also jumping on board

  15. Interesting…GreenGT H2 • GreenGT H2 to run at the 24 hours of Le Mans • Date: 22 and 23 of June 2013 • Powered by 2 hydrogen fuel cells • Set out to prove that hydrogen fuel viable in motorsports. • Top Speed 300Km/h or 186mph • 40 minutes per tank • http://www.youtube.com/watch?v=Lybj5sk7UZQ
