2 Checklista för hållbar utveckling 1. Analysera och formulera de ursprungliga villkoren 2. Upprätta en detaljerad beskrivning av det nuvarande systemet 3. Analysera befintliga mål för hållbar utveckling pålokal, nationell och Europeisk nivå 4. Identifiera och analysera viktig teknik som stödjer en långsiktigt hållbar utveckling 5. Identifiera nyckelaktörer i regionen 6. Formulera och analysera möjliga vägar till ett mer hållbart energisystem 7. Fastställ en handlingsplan

3 Sex fallstudier Göteborg, Sverige Dunkerque, Frankrike Gdansk, Polen Valenciaregionen, Spanien Lochem, Holland De Stoure Houtman, Arnhem, Holland

4 Gothenburg Present energy system Prime energy sources Electricity Petrol/Diesel Natural gas Waste heat Biomass Consumers Heavy industry Road/Sea transport Heating of buildings Electricity consumers Other remarks of the system The district heating system allows making use of low quality waste energy Traffic situation locally starts to be saturated. Distribution and networks Electricity grid: 100 % coverage District heating grid: 90 % coverage Natural gas grid: lower coverage Large industrial clusters 3 tunnels/bridges over the river Tram system Present key technologies District heating enables recovery of low quality waste heat and use of bad fuels District cooling, by using surplus heat during summer time. CHP The natural gas grid Biogas production and injection Renewable electricity production (wind, pv, wave) Cars, Buses, Trams

6 Gothenburg Most important goals (2020) 30 % reduction of CO 2 in the non trading sector (City of Göteborg) Hits the transport sector; road transports, shipping and aviation Goal is derived from national environmental quality goals. Another 15 will be formulated All new buildings passive (City of Göteborg) Started to be applied in K2020 No increase in private traffic (City of Göteborg) Large investments in public transport Urban wind and solar electricity production (City of Göteborg) Not in place yet, but forthcoming (EU)(National level: ) May interfere with local goals (discouraging waste heat) Enlargement The Gothenburg area will have 1,5 million inhabitants (City of Göteborg) Implies more transport not less

7 Gothenburg Most important goals (2050) Sustainable -and fair level of CO 2 emissions (City of Göteborg) based on ppm concentration and per capita allowance Results in 60-80% reductions compared with today Goal is derived from national environmental quality goals. Another 15 will be formulated Completely fossil free energy production (Göteborg Energi) 35 % reduction of end use of energy (Göteborg 2050) Entirely fossil free energy system (Göteborg 2050)

8 Gothenburg Most important key actors City of Göteborg (including Göteborg Energi, housing companies etc) Local city planning and energy planning has a huge impact on sustainability The municipality controls many of these actors, but they need to be better coordinated Industry (Including Volvo companies, SKF, Refineries and Stena) Most of the large industries in Gothenburg have important roles in developing a sustainable transport sector Universities Chalmers and other institutions are where tomorrow s solutions are being born External policy makers (EU, Stockholm) Of course these are controlling the limits of what can and can t be done KalåAda An active involvement of the citizen is necessary for a truly sustainable development

9 Gothenburg Key technologies District heating / cooling makes using waste heat and low quality fuels possible When heating demand declines, hot water and cooling demand remains, or possibly grows Natural gas grid Provides infrastructure for sustainable transport fuels, raw material for chemical industry and fuel biomethane. May include LNG infrastructure. Gasification of biomass Generally the most efficient way of converting biomass and waste, to fuel or chemical building blocks Public transport The most difficult issue is the traffic issue. Innovation required. Electric, hydrogen or methane powered vehicles The development of vehicles is crucial, and which technologies that will dominate will influence the relative importance of above technologies. Passive houses Eliminated heating demand is the easiest way of drastically improve energy efficiency in society

10 Gothenburg Trescenarier Electrifying Short term: 1 cent/kwh Mid term: Green electricity bigger than fossil fuels Long term: No fossil fuels A major breakthrough in green power production Cheap electricity More electric applications (transport, heating/cooling) Less demand for fossil fuels No nuclear or CCS Biomass to chemicals Slow development of energy efficiency Heat wave Short term: 500 /ton Mid term: 500 /ton Long term: No CO 2 emissions Dramatic climate change Biomass questioned CCS and nuclear grows fast Energy efficiency even faster Geopolitical consequences Changes in life style May lead to Electrifying or other revolutions Business as usual 1 % per year Current trends continue without major disruptions Increasing prices of fossil fuels All RES are important Energy efficiency important Economic growth cancels out effects of higher energy prices CCS and/or Nuclear important ways of buying time Best scenario for Swedish/Gothenburg competetiveness

11 Business as usual

12 Business as usual -Utmaningar Attha målären bra början, men de måste genomföras också Det måste finnas en balans mellan långsiktig strävan och en flexibilitet att hantera de hot och möjligheter som dyker upp längs vägen

13 Svaret får en fråga -Borgmästaravtalet EU-kommissionens utmaning till städerna Gå längre än lokalt Göteborg var bland de första som skrev på Samma utgångspunkt som i Pathto RES vi är på rätt väg Olika systemgränser

14 Borgmästaravtalet såhär långt Handlingsplan inlämnad Stor nytta av grundarbetet i Pathto RES Hypotesen håller, men utan marginal Eleffektivisseringoch elproduktion viktigaste åtgärdena Systemgränsfrågorna har en avgörande betydelse Det är ingen fördel att ha gjort mycket innan

15 Slutsatser/reflektioner Fungerar metodiken? Ja Intressant samling fallstudier Intressanta räkneövningar Tur att Borgmästaravtalet kom Göteborg är relativt väl rustat med mål
