1. First attempt Canada, 1930s –Imported almost all its fuel –Niagara Falls’ hydroelectric generating capacity was only 30-40% used –There was no way of storing the rest of the energy A. T. Steward –Uses the surplus to make H 2 –Uses most of the H 2 for fertilizers –Plans to use the rest for residential hitting and to power vehicles –The project is abandoned because cheaper natural gas appears

2. Conclusion There is a lot of wasted energy, which could be stored H 2 is a very good way of storing it Even if using H 2 is ecological, people will go for the cheaper alternative

3. Producing Hydrogen Source: American Chemical Society

4. Hydrogen Economy Source: Green Island Intl. Ltd.

5. The Past 1800 – electrolysis is invented 1807 – first hydrogen car 1845 – first fuel cell 1889 – first practical fuel cell 1920 – first practical hydrogen car 1959 – first fuel cell vehicle 1970 – first plans for a H 2 economy 1988 – first hydrogen plane

6. Present Fuel cell cars H 2 gas stations Current price = 1 mil. $ On the road = 100-300 Build models = 200 Competitors : hybrid improved gasoline Worldwide = 120 + 40 Japan = 12

7. The Present Cogeneration Current price = 1 mil. Yen Installed = 600 Economy = 40% Savings = 26% C0 2 reduction = 40% Other Fuel cell bus Fuel cell bike Fuel cell laptop

8. The Future (maybe) 2010 – household cogeneration systems spread (Japan – more than 10000) 2015-2020 – fuel cell cars will be mass produced and become competitive 2030 – Japan has 15 mil. FCV cars (20%)
