Update on the Carbon Mitigation InitiativeRobert SocolowPrinceton University St. James Square, London January 18, 2013
Goals of this talk • The goals of this talk are: • to introduce CMI • to review the current program • to describe the CMI research frontier • to explore areas of collaboration
Introduction • BP-Princeton interaction • Princeton University considers CMI to be one of its most successful collaborations with industry. Princeton researchers have complete independence, while sustaining two-way communication with BP leadership in the U.K. and the U.S. • Current Roster • 87 people in CMI: • 19 professor-level investigators • 68 post-docs, graduate students, and support staff Carbon Mitigation Initiative Annual Report 2011
CMI Mission Statement The mission of CMI is to lead the way to a compelling and sustainable solution of the carbon and climate change problem. By combining the unique and complementary strengths of the CMI parties – a premier academic institution and an influential global company – CMI participants seek to attain a novel synergy across fundamental science, technology development, and business principles that accelerates the pace from discovery, through proof of concept, to scalable solution. We are considering adding, at our next Annual Meeting: CMI’s mission is also to foster mutual learning that deepens the participants’ understanding of the climate science and technology frontier, business priorities, policy implications, and other critical climate-and-energy issues.

Areas for Collaboration I hope we can discuss these three questions: Princeton researchers are path-breakers at the climate science frontier. How can the value this work to those who create BP’s medium-term policy be increased? BP conducts, internally, sophisticated evaluations of emerging technology (I assume). Those of us (at Princeton and elsewhere) who contribute to energy analysis in the public domain would benefit from understanding BP’s methodologies, inputs, and conclusions. Examples are gas-to-liquids, geothermal energy, and methane clathrates. Can confidentiality obstacles be reduced to enable real and deep exchanges of views? Princeton researchers (especially in the Engineering School) want to work on basic problems that have important applications. Princeton leaders in hydrology redirected a substantial portion of their work to address subsurface CO2 studies as CCS emerged. At present, leaders in fluids and molecular modeling are looking for insights into emerging areas. What kind of BP-Princeton dialog could be mutually productive?
CMI leaders: Science Science Group: Left to right: Bender / Hedin / Medvigy / Morel / Pacala / Sarmiento Single highlight: Bender finds1.3 million year old ice near the surface in Mullins Valley, Antarctica, 0.5 million years older than the ice in the deepest ice cores. The atmospheric CO2 concentration may be inferable (see Annual Report, p. 51).
Participation in the ESC Total cropland today (grey bar) and in 2050 based on increased demand for food energy, decomposed by the contributions (red and green bars) of population growth (pop), income (income), crop productivity improvements (yield), and variation in diet (to either North American (NA) or Asian (AS)). Red bars indicate an increase and green bars a decrease in the cropland required by mid-century.
Ocean pH time series Slope: 0.2 pH/century (60% increase in H+ concentration) CO2 level in atmosphere at Mauna Loa; CO2 level and pH in nearby ocean at Station Aloha. Modified after R.A.

Attribution of extreme events • Confidence in attribution is growing • Stronger statistical signals and larger data bases • Higher resolution models with better physics • aerosols delay monsoons (GFDL) • bi-stable systems can flip (e.g., ocean circulation) • Heat waves > Droughts > Hurricanes: descending order of confidence.

Pacala, talk at Dartmouth, 2012
Pacala and the Land Sink (new work) Bottom line: Fortunately, that part of the terrestrial sink due to carbon fertilization should retain its strength in a high-CO2 environment, providing negative feedback. In particular, neither N nor P scarcity will degrade the sink. The Pacala Group’s models incorporate the height-structured competition for light. In their models, as a nutrient (N, P) becomes scarce, trees store more carbon, rather than less (as conventional wisdom has maintained) . The tree’s most competitive strategy is to invest in making wood so as to grow taller. Wood has very high C:N and C:P ratios, compared to other plant tissue, so N and P scarcity promotes, rather than inhibits, the terrestrial carbon sink. Source: Drawn from S. Pacala, talk at Dartmouth, 2012, verbatim and paraphrasing.

CMI leaders: Low-C energy Low-Carbon Energy Group (formerly, Capture Group): Left to right: Arnold / Kreutz / Larson / Socolow / Williams Single highlight: Williams’ Energy Systems Analysis Group (ESAG) continues to be a node in the research community that explores chemical energy conversion of biomass to fuels (torrefaction, gasification, Fischer-Tropsch synthesis), far outnumbered by those who are developing biological energy conversion (enzymes).
Current and Planned CO2 Pipelines and CO2 EOR Projects in the U.S. At present 60 MtCO2 is used annually in 114 projects to provide, via 6000 km of pipelines, 380,000 b/d of crude oil (6% of total US crude oil production). Energy Secretary Chu requested that the NCC prepare a report for him on carbon capture and storage for coal energy systems, with emphasis on storage via CO2 EOR . The economic & technical potentials for CO2 storage in the US: 18 & 43 GtCO2, respectively.

What Are Opportunities in China for Linking Coal Energy Conversion to CO2 EOR? Massive coal power fleet is relatively new, vs. relatively old in U.S. China is ahead of U.S. in deployment of both gasification and synthesis technologies. • Pins represent 400 chemical plants in China releasing concentrated CO2streams • These plants use both coal gasifiers and synthesis reactors to make chemicals • Green areas are sedimentary basins where suitable aquifer storage sites might be found • Source: Zheng, Z., Larson, E.D., Li, Z., Liu, G., and Williams, R.H., 2010: “Near-Term Mega-Scale CO2 Capture and Storage Demonstration Opportunities in China,” Energy and Environmental Science, 3: 1153-1169.

CMI leaders: Fluids Fluids and Energy Group (formerly, Storage Group): Left to right: Celia / Debenedetti / Panagiotopoulos / Prevost / Stone / Tromp Single highlight: Celia asks if the left hand knows what the right hand is doing, when a shale-gas production site is chosen without reference to whether the host shale doubles as CCS “caprock.” If so, production will shatter what otherwise could have been a seal against the upward migration of stored CO2 (see Annual Report, p. 29).

Nordbotten and Michael Celia “We have focused the book on basic concepts needed to understand subsurface storage of CO2, with a focus on mathematical models used to describe storage operations.” (from the Preface) http://www.wiley-vch.de/publish/en/books/ISBN978-0-470-88946-6

CMI leaders: Integration Policy and Integration Group: Left to right: Glaser / Oppenheimer / Pacala / Socolow Single highlight: In “Wedges revisited,” published on-line with ten comments, Socolow suggests that reframing climate change as requiring “iterative risk assessment” might provide a Restart button for carbon policy formulation. The paper urges a rhetoric that features “unwelcome news,” “incomplete science,” and “fraught solutions.”
Communicating uncertainty: How much hotter will summers be? Note: The uncertainty shown is due to alternative emissions paths, not alternative climate models. This graph probably shows how winters could feel too [to be verified]. Figure from James McCarthy, Harvard NECIA, 2007 (see: www.climatechoices.org/ne/)
Non-linearities and bi-stable states abound: The thermohaline circulation (THC)
Never have so many been asked to predict so much while knowing so little… • 100’s of operational decisions = 100’s of free parameters in global biosphere models. • If not for the crisis, I [Steve Pacala] wouldn’t be ready to build such a model for many decades or a century or more. • We must improve the fundamental biological basis of the models.

CMI’s Carbon Commitment CMI will sustain its leadership in the integration of science, technology, and policy related to climate change. CMI will remain a “steward” of the climate change problem, so that when attention is refocused, the CMI partners will be ready.
