Offshore energy supply with minimal CO2 release

Request Number N186360

Need details

Statoil is looking for solutions, methods and/or technologies which can enable offshore power and heat generation with minimal or zero CO2 release. Proposals should address one or both of the following themes:

  • Reduce carbon intensity of power and heat generation by maximizing energy efficiency or minimizing the carbon content of the energy source (fuel)
  • Full or partial capture of CO2 using compact technologies





Statoil and the Norwegian Oil and Gas sector seek to reduce CO2 emission from future oil and gas developments, both in Norway and internationally. Power and heat for offshore oil and gas production facilities is today typically provided by compact and lightweight gas turbines with onsite natural gas as a fuel and heat recovery from exhaust. An average turbine continuously produces 20 MW of power and emits around 100 000 tons of CO2 per year. A typical facility may include 2-4 turbines, each with an installed weight of 200 metric tonnes. Innovative ideas and solutions are needed to achieve major CO2 reductions in future oil and gas projects in an economical acceptable way.


Energy saving measures, alternative energy sources and full or partial electrification of the facilities are part of the overall approach to reach the emission goals. But Statoil also wants to explore technologies that can remove CO2 from flue gases. To be successful for use on an offshore facility a compact low weight solution is needed. Since conventional CO2 capture and storage (CCS) approaches are in general far too large and heavy for offshore use, a successful proposal does not need to capture 100% of the CO2. A compact solution that can remove 40% would already be a significant step forward.


Key Success Criteria
  • Safety is essential for offshore use.
  • Technologies should be able to continuously deliver minimum 20 MW of power and 5-10 MW heat at around 300oC, and should be able to start and ramp power supply up/down as quickly as gas turbines.
  • Solutions should provide low carbon power and heat at competitive capital and operational cost
  • Technologies for offshore use have to consider space and weight constraints
  • Technologies should have low complexity and minimal maintenance and manning needs to enable offshore use
  • Completeness of proposed solution is important: All utilities, pre-treatment, after-treatment, ducting and support systems must be included
  • Technologies should be applicable on floating installations in deep water far from shore, and need to tolerate sea induced movement and tilt
  • All emissions to air or sea need to be considered, like NOx or any chemicals used for CO2 capture
  • Experimental evidence that supports the merits of the technology is an advantage
  • Capture solutions should remove at least 40% of CO2 in flue gases, but preferably 80%
  • Capture solutions should produce storable CO2 with 80 bar pressure and 10 ppm(vol) O2 as a guideline. Alternatively, the proposal can include a transport and storage solution for CO2.



Possible Approaches

Possible approaches might include, but are not limited to:

  • Radical changes in turbine or thermal power generation system design, including use of reciprocating engines or combined cycle systems
    • Allowing increase in thermal efficiency level from current 30% to around 50%
  • Power supply based on modification of gas turbine design to enable use of alternative fuels
    • e.g. use of high hydrogen containing fuels, including fuel supply concept
  • Novel ways to make use of the natural gas feedstock extracting more energy, e.g.
    • Natural gas to electricity via chemical conversion
  • CO2 capture solutions may involve some of the following options
    • Compact mass transfer equipment for absorption/desorption of CO2
    • Gas separation membranes
    • Adsorption/desorption technologies
    • Absorption offshore and desorption onshore with transport of rich and lean sorbent (needs viable logistics and offshore loading/unloading solution)
    • Integration with offshore power/heat generation system and/or oil and gas processing facilities
    • Use of fuel cells
    • Exhaust gas recycle



  • Renewables like wind, solar or tidal waves are not excluded, but these need to be part of a cost-effective method that is able to continuously provide 20MW of power plus heat


Approaches not of interest
  • Solutions that require offshore oxygen production and/or handling of oxygen offshore
  • Solutions involving toxic or non-biodegradable chemicals
  • Solutions that can give harmful emissions to air or discharges to sea
