Hello, Hard Core

The louder the alarm, the greater the number of people who will drop what they are doing and try to help. Some scientists and engineers are urging a broader agenda:

If the problem is CO2 emissions, surely nuclear power is part of the solution.

If the problem is planetary, fix the planet.

Nuclear Power

New Paper: Robert H. Socolow & Alex Glaser, “Balancing risks: Nuclear energy & climate change,” Daedalus, Fall 2009, pp. 31-44. Special issue: The Global Nuclear Future, Volume 1.

1. Nuclear power could make a significant contribution to climate change mitigation.

2. A global scale-up of nuclear power is unwise until an international management regime for nuclear power is in place that makes both nuclear war and nuclear terrorism less likely with nuclear power than without it.

3. The next decade is critical. A world considerably safer for nuclear power could emerge as a co-benefit of the current nuclear disarmament process.

4. Nuclear power will not benefit climate change if its contribution is withdrawn a decade or two after global scale-up begins, as a result of the coupling of nuclear power to nuclear weapons.

5. Making climate change the world’s exclusive priority is dangerous.

1500 GW nuclear power by 2050

One view of nuclear expansion to 1,500 GW. 58 countries use nuclear energy, but only about 40% of the capacity is outside the OECD.

Risk Management: We must trade the risks of disruption from climate change against the risks of disruption from mitigation. We and our children and grandchildren will search for an optimum pace.

I will apply, for the benefit of the sick, all measures that are required, avoiding those twin traps of overtreatment and therapeutic nihilism.*

Preliminary conclusions (personal, not yet the committee’s, and off the record)

It is too soon for policy. The world needs to stay technically focused until more is understood about the cost:

If direct capture is cheap ($50/tCO2), investment will soon flow. Diminished resolve to pursue conventional mitigation results. “Overshoot” emissions trajectories become credible.

If it’s horribly expensive ($5000/tCO2), the world should not be distracted by it.

Today, we guess that it would cost above $500/tCO2 if deployed at scale.

Note: Options costing even more than $500/tCO2 influence the optimum price schedules generated by century-scale integrated assessment models. (Air capture is a “back-stop technology.”)

Early demonstrations are invaluable!

A significant impact on climate requires immense storage volume below ground. Storage was not studied in the POPA report.

A sweet spot for new materials:Fast kinetics, modest enthalpy of binding

Box 3.5, Figure 1. Rate constant (M-1s-1) versus the absolute value of the reaction enthalpy (kJ/mol) for a series of chemical absorption and adsorption processes.

We may recommend limited, fundamental, materials-focused air capture R&D “blended into” post-combustion capture R&D. Compare with Obama’s Fossil Energy budget request, Feb 1, 2010: “Transformational Technologies for Carbon Capture to identify and focus on innovative carbon capture technology breakthroughs for point sources and the atmosphere” (my italics).

Goodbye, Annex I

AQUILA MATH: At Aquila last summer the G-8 announced two percentage-reduction goals for 2050 (relative to some recent time):

50% reductions in global emissions, and

80% reductions in OECD emissions.

Hardly anyone observed that these two goals require a third, because almost exactly half of global emissions today come from outside the OECD:

20% reductions in non-OECD emissions

The point isn't the numbers. Rather, it is the manners. The non-OECD was told. It was not asked.

The same two goals reappeared in Copenhagen.

Page 15: Hello, Hard Core; Goodbye, Annex I An overview of “integration” research

The post-post-colonial world

Copenhagen was supposed to be the event at which the two-tier world of the 1992 Rio Convention and the Kyoto follow-on (featuring Annex1 and NonAnnex1 countries with "common but differentiated responsibilities") would morph quietly and quickly into a one-tier world of closely coupled obligations. What astonished me was that anyone was "surprised" that the task proved difficult.

1992 to 2009: a post-colonial worldview. Former colonial powers feel guilt, former colonies expect compensation. 2010: the world is seeking to invent a post-post-colonial world. Copenhagen brought home that the developing countries will determine what kind of planet human beings live on. Over the coming century they will dominate world wealth and consumption, resource depletion, and environmental damage. Western influence is limited and will wane, yet Western leadership is essential now.

Innovative analyses of China policy

LI Jie’s map shows the five provinces of China with largest emissions reduction assignments in a scheme based on “high-emitting individuals.”

Beyond per capita

We can’t solve the climate problem without moving beyond “per capita” – looking inside countries.

Safe and Fair: Quantifying heritage emissions

It is widely asserted that “fairness” should take history into account (heritage emissions).

New concept: Cumulative Per Capita Emissions for some group over some time-interval partially past and partially ahead. (Use the group’s average population over the interval.)

Fairness principle: Equal Cumulative Per Capita (ECPC) emissions for two or more groups and the same time interval (e.g., 1850-2100).

The ECPC Scheme at work:Compensating Emissions for the 1850-2100 Interval

Every additional ton of future Annex1 CO2 emissions legitimates five tons of future CO2 emissions from the NonAnnex1 countries.

How helpful CO2 removal would be! Each 800 GtCO2 removed lowers concentration by approximately 100 ppm (assuming neutral natural sinks).
