WP 6: Long-term sustainable re-use of depleted fields  

1. Introduction

This work package will in close collaboration with work package 7 have focus on sustainable re-use of depleted fields and integration needs. We will identify regions on the NCS that are most suited for which storage purposes, from the perspectives of economics, practical constraints, performance and safety.

2. Research goals

We will advance the understanding for screening of depleted reservoirs to enable re-use of late-life fields for commercial H₂/CO₂ storage or another environmentally friendly purpose.

3. Delivery

• Establish screening criteria for depleted fields in the framework of CO₂/H₂ storage
• Transfer findings from other WPs to large scale H₂/CO₂ storage in depleted fields
• Screened NCS fields for commercial H₂ storage; desktop studies of 1-2 representative depleted fields
