Gassnova’s reports about Longship

In this section you will find Gassnova’s reports to the Ministry of Energy from the FEED phase and Gassnova’s lessons learned reports.

Report about regulatory learning

The report “Regulatory lessons learned from Longship” is written by Gassnova. In this report the regulatory issues and challenges facing Longship and how these are resolved are discussed in light of the state’s different roles. The report is written for subsequent CCS projects, government actors and others working to facilitate CCS projects.

Key lessons learned

The document below presents key learnings from the development of Longship from the pre-feasibility study in 2014 up to completed FEED studies and the industrial partners FID’s in 2020. The report is written for subsequent CCS projects, government actors and others working to facilitate CCS projects.

Full chain report

Gassnova’s full chain CCS report describes the different CCS chain alteratives and costs i.a. The cost estimates in this report is not latest estimates.

Evaluation report

Gassnova’s evaluation of Fortum Oslo Varme’s (now Hafslund Oslo) and Heidelberg Materials’s FEED reports.

Benefits realisation

A working program set up to achieve the Norwegian state’s project goals has been named “benefits realisation”. All industrial partners are involved in this program and Gassnova is coordinating the work.

Evaluated the Northern Lights’ FEED report

Gassnova has evaluated the Northern Lights’ FEED report.

CO₂ footprint

In cooperation with DNV GL and Carbon Limits AS, Gassnova has developed a tool to calculate the amount of CO₂ emitted during any given CCS operation and calculated the CO₂ footprint for the alternative CCS chains in the Norwegian project. In september 2020 FOV asked to revise its input data for the footprint calculations.
