2
CLIMATE BOTTOM LINE Most warming goes into oceans & poles Super-hurricanes are now the norm 10 more years of inaction = 4° to 6+° F warming Greenland goes (20+ feet of sea level rise) 20 years = 6° to 10+° F warming Serious Antarctic ice loss (80+ feet) Sea level rise 6 to 12 inches per decade possible
4
At 550 ppm, 60% of top permafrost goes. At 690, 90% (lt. blue) (Lawrence, NCAR, 2005) Tundra C ≈ Atmo C Much of it CH4 Not in IPCC models TUNDRA FEEDBACK
5
TIME FOR DELAY HAS RUN OUT We’re at 380 ppm CO2, rising 2+ ppm/yr If 500 & rising in 2050, plan on 700+ in 2100 Global emissions must peak ~2025 We must cut CO2 emissions >50% by 2050. We must stop building traditional coal plants We must have average new car 60 mpg in 2040
6
New Coal Build by Decade Source: IEA, WEO 2004 221 500 670 >$1 trillion in misallocated capital
7
Unconventional Oil is Climate Disaster Tar Sands: Use CH4 to make C-intensive fuel Coal-to-Oil: Double the CO2 emissions Still a bad idea with carbon capture Enhanced Oil Recovery diverts captured CO2 Should NOT be valued as geologic storage Shale: 1.2 GW for 100,000 barrels a day
8
The 7 Barriers to AFVs 1) High first cost for vehicle 2) Storage (i.e. limited range) 3) Safety and liability 4) High fueling cost (compared to gasoline) 5) Limited fuel stations: Chicken & egg problem 6) Not a cost-effective pollution-reducer 7) Tough competition: Hybrids
9
The Hype About Hydrogen “Total time to noticeable impact … is likely to be more than 50 years.” —Heywood, MIT, 7/05 “If I told you ‘never,’ would you be upset?” Toyota’s Bill Reinert on when H2 replaces gas, 1/05 “Forget hydrogen, forget hydrogen, forget hydrogen.” — James Woolsey, 1/06 After “CO2 emissions from electricity generation are virtually eliminated….” — Science, 7/03
11
Car of the Future: Plug in Hybrids 20-mile electric range, then reverts to hybrid Could displace half of gasoline Works best with carbon cap Blend in cellulosic ethanol Why use future clean electricity for H2? Plug in uses electricity 3 to 4 times more efficiently Make use of existing infrastructure/vehicles
12
Nuclear Hydrogen Fuel Costs Three Times More Than Nuclear Electricity (Idaho National Lab Analysis, 12/05)
13
David Barber, Nuclear Programs, INL, 3/05 “Not even nuclear energy can turn hydrogen into a winner.” “There certainly will not be an overabundance of clean energy to squander on an inefficient hydrogen loop, particularly when the same tasks can be accomplished directly with the original electricity. Not this century, anyway.”
14
2020 Vision Oil Prices at Current or Higher Levels Global desperation about global warming Nuclear electricity resurgence very possible Hybrids the dominant vehicle platform Plug-in hybrids the rapidly emerging platform H2 fuel cell vehicles probably a dead end No future for nuclear hydrogen jromm@cap-e.com
