2 Statoil. Hydro climate policy • Statoil. Hydro’s ambition is to provide energy to 2 Statoil. Hydro climate policy • Statoil. Hydro’s ambition is to provide energy to meet the growing demand that is needed for economic and social development while at the same time caring for the environment and actively combating global climate change. • Statoil. Hydro recognizes that there is a link between the use of fossil fuel and man-made climate change. We will apply a precautionary approach in operations and business development, and take into account the impact on climate change and sustainable development before entering into new businesses and projects. • We will achieve our amibtions through the following measures: (1 -7) – Measure 1, 3 and 4 will be further presented

3 A new energy platform • We will increase energy efficiency • We welcome 3 A new energy platform • We will increase energy efficiency • We welcome global mechanisms for carbon trading • We will keep our position as a world- leader in carbon capture and storage • The cornerstones in our new energy portfolio will be offshore wind and biofuel

4 SH climate policy measure 1 - Operations • We strive to implement the 4 SH climate policy measure 1 - Operations • We strive to implement the best available technologies and practises to operate our facilities with a high degree of energy efficiency, and to reduce greenhouse gas emission – The last 3 years Statoil. Hydro has cut the annual CO 2 emissions on NCS by ca. 200 000 tonn CO 2 through energy efficiency measures – Energy management in use – CO 2 tax has made many energy efficiency measures ”profitable”

11 Statoil. Hydro cooperation with Petroleos Mexicanos • Cooperating to close down gas flares 11 Statoil. Hydro cooperation with Petroleos Mexicanos • Cooperating to close down gas flares on the oil field Tres Hermanos • Ongoing application pocess for approval from UN – Clean Development Mechanism (CDM), Kyoto Protocol

12 Oil sand Canada • Steam Assisted Gravity Drainage (SAGD): • Energy consuming: 40 12 Oil sand Canada • Steam Assisted Gravity Drainage (SAGD): • Energy consuming: 40 – 65 kg CO 2 / barrel o. e. • Large consumption of water • Statoil. Hydro goal: Reduce steam needed to warm up sand, reduce energy needed • Possible measures: – Re-use water – Use of solvents in steam – CO 2 Capture and Storage

13 SH climate policy measure 4 – CO 2 capture and storage (CCS) • 13 SH climate policy measure 4 – CO 2 capture and storage (CCS) • We are actively working to establish CCS as business opportunity and evaluate CCS solutions as part of CO 2 intensive projets – Sleipner: 1 mill. ton CO 2 per year is separated from natural gas and injected in deep saline aquifer. – Reduces CO 2 emission by 13% on the Norwegian Cont. Shelf – In operation since 1996

14 CO 2 Capture and storage (CCS) – removal of CO 2 from natural 14 CO 2 Capture and storage (CCS) – removal of CO 2 from natural gas • Carbon capture and storage – Sleipner – In Salah, Algeria – Snøhvit Sleipner

15 CO 2 Capture at Mongstad • • Result of permitting process for Mongstad 15 CO 2 Capture at Mongstad • • Result of permitting process for Mongstad combined heat and power plant (EVM) October 2005. Statoil and the Norwegian Government entered into an agreement on October 12 th 2006 to cooperate on CO 2 capture at Mongstad: • European CO 2 Test Centre Mongstad (TCM) • June 20 th, 2007: Cooperation agreement between the Norwegian State and Statoil ASA extended with new partners: Vattenfall AB, Norsk Hydro Produksjon AS, Dong Energy Generation AS and AS Norske Shell for the planning phase 1). TCM owners are all parties who have a strategic interest in developing CO 2 capture technology • Large scale CO 2 capture plant at Mongstad • CO 2 Masterplan Mongstad, a Statoil. Hydro ASA project, shall in accordance with the agreement present a master plan for large scale CO 2 capture to the Government by the end of 2008. Further development of large scale CO 2 capture at Mongstad is at the discretion of the Government

17 European CO 2 Test Centre Mongstad • The test facility shall, in accordance 17 European CO 2 Test Centre Mongstad • The test facility shall, in accordance with the agreement, reduce risk and cost for large scale CO 2 capture. See next slide. • The plant shall be designed to capture 100 000 tonnes CO 2. The captured CO 2 will be released back into the atmosphere • • Two CO 2 capture technologies will be tested on two different flue gas sources Technology goals: • Amine: – Flexible demonstration plant – Test of equipment, internals, process configurations – Test of different operating conditions and different / new solvents • Chilled ammonia: – Validation of process and engineering design for full-scale application – Determination of performance – Gain more insight into aspects as thermodynamics, kinetics, engineering, materials of construction, safety, process, environmental etc. • Reducing environmental risk related to large scale CO 2 -capture – The capture technologies have their own unique environmental footprint which presently are not fully understood

18 CO 2 Masterplan Mongstad • The large scale CO 2 capture plant is 18 CO 2 Masterplan Mongstad • The large scale CO 2 capture plant is designed to capture 2. 1 million tonnes of CO 2 from two separate sources; the combined heat and power plant (CHP) and one Mongstad refinery source – the residue catalytic cracker • Building a large scale CO 2 capture plant will require technology qualification (TQP). TQP is recommended to be based on results/information from pilot plants, demonstration units and commercial units in addition to TCM. Theoretical studies and mathematics modelling are also integrated parts of the TQP is required not only the capture technologies, but also for large mechanical equipment • The captured CO 2 will transported a suitable reservoir for storage. Investigation of transport and storage solutions is the responsibility of the MPE and Gassnova SF. The Utsira and Johansen formations are under assessment as potential storage locations
