StatoilHydro climate policy
• StatoilHydro’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.
• StatoilHydro 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 global mechanisms for
carbon trading
• We will keep our position as a worldleader 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 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 StatoilHydro has cut the annual CO2 emissions on NCS by ca.
200 000 tonn CO2 through energy efficiency measures
– Energy management in use
– CO2 tax has made many energy efficiency measures ”profitable”

Important to design energy efficiency in field development!
Kvitebjørn: High Pressure/High Temperature - from challenge to advantage
• Emissions to air:
– 2,5 kg CO2 eq./barrel o.e
– 0.0003 kg NOx /barrel o.e.
• Reservoir pressure utilized for gas
export and injection of produced water
to the Utsira formation
• Well stream heat utilized as process
heating
7
Heimdal new power generator - replacing old turbines
• Transported to Heimdal
Summer 2008
(Saipem 7000)
• New module will be integrated
with 14 different systems
• Wight: 550 ton
• Cost: almost 1 billion NOK
• Annual reduction
of CO2: 50 000 tonn
• 25% reduction
of Heimdal’s emissions
8
Preparing for power from shore on floating installations
• Gjøa: Planned start up 2010
• Power from Mongstad combined heat and power plant will supply Gjøa
– Better energy efficiency than traditional offshore turbines
– Reduced emissions
• Troll A, power from shore
since start up in1996

Flare gas recovery system
• Gullfaks A: Closed flare in 1994
• System later used on ca. 30 installations in Norway, UK, Aserbadsjan and Trinidad
• Worldwide: Annual flaring/ventilation of 150 billion m3 gas, resulting in 400 mill ton CO2.
• Norway: Flaring of 100 mill m3 gas, 0,1% of flared volumes worldwide
11
StatoilHydro 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 – 65 kg CO2 / barrel o. e.
• Large consumption of water
• StatoilHydro goal: Reduce steam
needed to warm up sand, reduce
energy needed
• Possible measures:
– Re-use water
– Use of solvents in steam
– CO2 Capture and Storage
13
SH climate policy measure 4 – CO2 capture and storage (CCS)
• We are actively working to establish CCS as business opportunity and evaluate CCS
solutions as part of CO2 intensive projets
– Sleipner: 1 mill. ton CO2 per year is separated from natural gas and injected in deep
saline aquifer.
– Reduces CO2 emission by 13% on the Norwegian Cont. Shelf
– In operation since 1996
14
CO2 Capture and storage (CCS) – removal of CO2 from
natural gas
• Carbon capture and storage
– Sleipner
– In Salah, Algeria
– Snøhvit

CO2 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 12th 2006 to cooperate
on CO2 capture at Mongstad:
• European CO2 Test Centre Mongstad (TCM)
• June 20th, 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 CO2 capture technology
• Large scale CO2 capture plant at Mongstad
•
CO2 Masterplan Mongstad, a StatoilHydro ASA project, shall in accordance with the agreement
present a master plan for large scale CO2 capture to the Government by the end of 2008. Further
development of large scale CO2 capture at Mongstad is at the discretion of the Government

European CO2 Test Centre Mongstad
•
•
•
•
The test facility shall, in accordance with the agreement, reduce risk and cost for large scale CO2 capture. See next
slide.
The plant shall be designed to capture 100 000 tonnes CO2. The captured CO2 will be released back into the
atmosphere
Two CO2 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 CO2-capture
– The capture technologies have their own unique environmental footprint which presently are not fully understood
18
CO2 Masterplan Mongstad
• The large scale CO2 capture plant is designed to capture 2.1 million tonnes of
CO2 from two separate sources; the combined heat and power plant (CHP)
and one Mongstad refinery source – the residue catalytic cracker
• Building a large scale CO2 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. TQP is required not only the capture technologies, but also for large
mechanical equipment
• The captured CO2 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
19
SH climate policy measure 3 – Renewable energy
