nordwest2050 - Prospects for climate-adapted Innovation Processes in the Model Region Bremen-Oldenburg in North Western Germany Metropolitan area Bremen- Oldenburg: 2.3 Mill. Habitants 5 year Project (2009-2014) Time Frame: about 40 years (2009 2050) 4 Sectors: Logistics & port management, food industry, Governance energy S.

Energy - a key sector within the Region 1/3 of Germany's Gas storage capacity within the MPR (LBEG 2010) 95% of Germanys Gas production located in Lower Saxony (high share of gas sources within the region) + 98% of potential gas resources (LBEG 2008, Gabriel et al. 2010) About 40% of Germany's shipped hard coal imports were landed in the five ports within the region (2010) 78% of Germany's petroleum imports landed Wilhelmshaven (2008) High Energy demand within the region, due to large industrial sector (Steel, automotive, wind energy, aeronautics + food industry) High share of renewables - 42% of total electricity production from renewables esp. Wind an Biogas (Total installed capacity: ~3.6 GW) S. Stührmann - CCRR - Dresden, May 2013 Source: Gabriel et al. 2010, LBEG 2008, LBEG 2010, www.energymap.de) 4/14

1. Theory - How we can guide innovation processes under uncertainty? The Resilience Approach In climate adaptation research uncertainties play an important role Our approach is based on the idea that ecosystems always are confronted with changing environments Following ecosystem theory, Resilience (Holling & Gundersson, 2006; Brand, 2006 ) could be a kind of guiding principle for this Despite all differences between social-technical systems & social-ecological systems, some principles seem to be transferrable Resilience describes the capability of systems to maintain their system services even under stress and in turbulent environments (despite massive external disturbances and internal losses) S. Stührmann - CCRR - Dresden, May 2013 6/14 (Holling & Gundersson, 2006; Brand, 2006, Gleich et al. 2010, Stührmann et al. 2012 )

2. Vulnerability assessment- Preliminary Findings (Current) regional energy supply system is well equipped for: Current regional energy supply system is not well equipped for: handling most foreseeable and continuous climate impacts handling known disturbances and uncertainties including predictable events in their planning surprises, including massive extreme events (e.g. flooding) non-quantifiable uncertainties /yet unknown disturbances handling local /regional conflicts (especially land + resource use) large scale restructuring (e.g. transition to decentralized system) S.

Low Exergy Solutions FOCUS: Geothermal cooling of a data center I Need for adaptation? Perspective: Energy supply High grid loads, due to increasing integration of renewables Waste heat potentials often unused Higher risk for blackouts during heat waves, if cooling demand increases (compression cooling - electr. driven Technology) Perspective: data center High Energy demand for cooling of data center (+ 50 to 150% of servers electric capacity) & high costs Increasing Temperatures & Heat waves Demand for high reliability (TIER 4 Standard) Increasing interest in green IT concepts S. Stührmann - CCRR - Dresden, May 2013 12/14
Low Exergy Solutions FOCUS: Geothermal cooling of a data center II Idea: using natural heat sinks for cooling to decrease peak loads in summer Build a redundant cooling system Combine new & standard technologies Increases Resilience by e.g: Increased diversity of used cooling technologies By switching to alternative cooling strategies -> decreasing peak load Implementation: combination of a free cooler with geothermal probes and integral wells Status: test drilling (200m) and simulation completed Planning process and contracting in final stage Authorization process started Finalization until autumn 2013 S. Stührmann - CCRR - Dresden, May 2013 Additional Benefits: High efficiency Lower C02 Emissions Low-maintenance costs High reliability Optional: Use heat pumps to store heat into the ground + using it for heating/cooling buildings around the data center 13/14
Conclusion & Open questions Climate adaptation is only a weak motive for innovation Innovation is dependent on motivation of stakeholders and regional situation Who found who? Relation between personal agenda of stakeholders & science Implementation of innovative candidates is difficult to systemize How to weigh different resilience demands (e.g. heat vs. electricity) against each other and against other political constraints? How to deal with a partly unsolvable contradiction: Increase in Resilience needs a minimum of e.g. redundancy, buffer and decentralization -> decreases efficiency? S.
