This subproject performs industry-driven case studies, each over a one-year period, to show emissions reductions from the implementation of technologies on the Norwegian Continental Shelf fields. Studies on the economic aspects of technology development through advanced techno-economic analyses are also performed.


The goal of LowEmission case studies is to develop  technology concepts that can lead to a minimum 5% reduction in offshore energy consumption and/or CO2 emissions. The industry-driven case studies are conducted over a one-year period to show emissions reductions from implementing technologies on the Norwegian Continental Shelf (NCS). Studies depend on industry partners making available data necessary to evaluate emission, weight and cost reductions.

Seven new case studies were initiated through an industry lead nomination prosses. The seven case studies will be completed in April 2023 and presented in webinar series in May-June. The seven case studies are listed below.

Application of heat pumps for better heat integration of process streams
Evaluating the use of HTHPs as an alternative for direct electric heating in case of electrification of offshore oil and gas production unit.

Emission reduction potential of Cold Flow demonstrated for a real field case
Demonstrate the emission advantage or possible energy saving as well as the technical limitations of Cold Flow, which enables flow of hydrocarbon production fluids at thermodynamic equilibrium in uninsulated pipelines, without the help of chemical modifiers.

Options for sequestering CO2 from offshore installations
Investigate and compare the cost, footprint and energy use associated with different local and small-scale CO2 capture and storage solutions.

Advanced power fluctuation control for combined wind, gas and steam turbine systems
Assess how advanced process control can guarantee reliable offshore power generation in a system with a combined cycle and wind power.

Ekofisk - Impact of wind turbines on gas turbine operation and power system stability
Quantify the impact of offshore wind turbines connected to the Ekofisk power system on gas turbine operation and power system stability, and to propose and assess possible measures to decrease undesired implications.

Electrification of the NCS with offshore wind and power to shore
Assess how best to reduce NCS CO2 power generation emissions by electrification from offshore wind energy with net power to shore.

Use of low- and zero-emission technologies and alternative energy carriers in supply vessel fleets
Accelerate the transition towards sustainable zero-emission offshore logistics by 2050 through an integrated application of zero emission fuels, energy-saving technologies and energy-efficient operations.


Three new Knowledge-building Project for Industry with LowEmission partners and research was granted in June. All three project proposals were based on findings from previous case studies. Demonstrating how the subtask contributes to identifying key barriers to implementing LowEmission technologies and how they can be overcome by focus and target R&D.

The three projects are:

  • DECAAMP, led by SP1 manager Adrina Reyes Lua
  • Sea Connect, led by SP3 research led by Emre Kantar
  • Hy4GET, led by SP6 manager Tore Føyen

This SP performs industry-driven case studies over 1-2-year periods to show emission reductions from implementing technologies on the Norwegian Continental Shelf fields. Studies depend on industry partners making the necessary data available to evaluate emission, weight and cost reduction. Industry plays a vital role in ensuring implementation through in-kind contributions/expertise. Studies on the economic aspects of technology development through advanced techno-economic analyses will also be performed.

Main objective

The main goal of the LowEmission Case studies is to develop technology concepts that lead to a reduction in offshore energy consumption and/or CO2 emissions based on the overall LowEmission objectives. The industry-driven case studies will be conducted over 1-2 year periods to show emission reduction from implementing technologies on fields on the Norwegian Continental Shelf. Studies will depend on industry partners making available data necessary to evaluate emission, weight- and cost reduction.

Main results

  • A general methodology for the LowEmission case studies was developed
  • Input on ideas and selection of case study topics was collected from industry and research partners
  • A discussion on field-specific case studies was initiated between Repsol and the research partners
  • Several concepts for both generic cases and a field-specific study were developed. Further evaluation of those will continue in 2020 in a close dialogue with LowEmission industry partners

Impact and innovations

  • Development of 2-4 novel concepts for Phase I: Case Potential integrating low emission technologies into existing and greenfield offshore energy systems, whereas 1-2 of these cases will Energy Supply and Demands KPIs CO2 equiv. emissions progress into Phase II of the case studies for detailed performance evaluation.
  • Use of Innovation strategies funding in 2020 is expected to boost activities in LowEmission which have been identified by industry partners to have high impact and short-term implementability potential.
