Energy efficiency: is it enough for fighting the Global Warming ? The role of CO2 Geological Storage now and in the post-Kyoto
scenario
Eco-innovation – opportunities and challenges
There is a wide scientific consensus on Global Warming
Impacts of Global Warming

It is not just Climate Change
CO2 is acidifying our oceans and will inflict severe ecological and economic damage later this century and in the next

Eco-innovation – opportunities and challenges
XX° century, exceptional warming: +0,6°C ; + 2°C on Arctic region
Antarctic: +3,5°C since 1945; important collapses (ex: 3250 Km2 in 2002)
Arctic: -40 % ice shell since 1945
In Italy: +1,4°C since 1950
80 % of the world glaciers and permafrost melt: - 8cm/y in Siberia, and 1,6 to 3,3°C in Alaska since 1980
Ocean warming (+1°C around NZ in 100 years): absorption reduced
Ocean level: 1,5 to 2 mm/y during the XX° century, 3 mm/y today
Biodiversity threatened by rapid change. Ex France: +0,9°C in one century = shifting of meteo conditions 150 m higher or 180 km northward. Consequences observed on fauna, flora, agriculture, fish …
Increase of extreme events
2025: 75% population in a 60 km distance from coastlines
Observations confirm reality of climate change and future impacts

Global Warming is not new but …. during a man’s life there are changes that happened in the past on geologic scale
Mean temperature on the ice surface in Antarctica (hist.) and CO2 concentrations (in yellow). Both are correlated with the deviation of Earth orbit (in blue). From about 1960, an high peak

Climate observations confirm anthropogenic contribution
Eco-innovation – opportunities and challenges
The production of CO2 cannot be avoided (because intrinsically related to the use of hydrocarbons)
Even though the development of renewable energy sources, hydrocarbons will remain the main energy source, passing from 87 % to 89 % in 2030.
All projections indicate an increment of about 65 % of energy demand in the period 2000-2030.
This will be mainly related to the growing of people having access to energy, while energy “pro capite” (in red) has been almost stabilized from the Seventies

Stabilization Wedges: Solving the Climate problems for the Next 50 Years with Current Technologies
S. Pacala and R. Socolow (Princeton University)
Stabilization curve at 550 ppm CO2 in the atmosphere
A “wedge” represents an activity that reduces emissions to the atmosphere that starts at zero to-day and increases linearly until it accounts for 1 GtC/year of reduced carbon emissions in 50 years:
It thus represents a cumulative total of 25 GtC of reduced emissions over 50 years.
Eco-innovation – opportunities and challenges
Some Options: increase efficiency in cars / buildings
Efficient vehicles
increase fuel economy for 2 billion cars (roughly four times as many as to-day) from 30 to 60 mpg
Reduced use of vehicles
decrease car travel for 2 billion 30 mpg cars from 10.000 to 5.000 miles per year
Efficient buildings
cut carbon emissions by one-fourth in buildings and appliances projected for 2054 (energy-efficient space heating and cooling, water heating, lighting and refrigeration in residential and commercial buildings). About half of potential savings are in developing countries
Eco-innovation – opportunities and challenges
Some Options: power plants efficiency / fuel shifting
Efficient baseload coal plants
produce twice today’s coal power output at 60% instead of 40% efficiency (compared with 32% today)
Gas baseload power for coal base load power
replace 1400 GW 50% efficient coal plants with gas plants (four times the current production of gas-based power)
Nuclear power for coal power
add 700 GW (twice the current capacity). Phase out of nuclear power creates the need for another half wedge
Eco-innovation – opportunities and challenges
Some Options: renewable energies
Wind power for coal power
add 2 million 1-MW-peak windmills (50 times the current capacity) “occupying” 30 million ha on land or offshore
Photovoltaic power for coal power
add 2000 GW-peak PV (700 times the current capacity) on 2 million ha
Wind H2 in fuel-cell car for gasoline in hybrid car
add 4 million 1-MW-peak windmills (100 times the current capacity)
Eco-innovation – opportunities and challenges
Some Options: biomass / forestation / soils management
Biomass fuel for fossil fuels
add 100 times the current Brazil or U.S. ethanol production, with use of 250 million ha (one sixth of the world cropland)
Reduced deforestation, plus reforestation and new plantations
decrease tropical deforestation to zero instead of 0,5 GtC/year, and establish 300 Mha new tree plantations (twice the current rate)
Agricultural soils management
by 1995, conservation tillage practices had been adopted for 110 million hectares of the world’s 1.600 million ha of cropland. If these techniques could be applied to all cropland, half to one wedge could be saved.
Eco-innovation – opportunities and challenges
Some Options: capture of CO2 and geological storage
Capture CO2 at baseload power plant (coal, natural gas, synfuels)
introduce CCS at 800 GW coal or 1600 GW natural gas
introduce CCS at plants producing 250 Mt H2/year from coal or 500 Mt H2/year from
natural gas (compared with 40 Mt H2/year today from all sources)
Apply geological storage at large scale
create 3500 Sleipner
20-500 %
