ACT4storage - Acoustic and Chemical Technologies for environmental monitoring of geological carbon storage. D3 - Nearshore evaluation report 2019

Abstract

This report is the second delivery of the CLIMIT demonstration project ACT4storage (Acoustic and Chemical Technologies for environmental monitoring of geological carbon storage). The ACT4storage project is funded by Gassnova and Industry Partners. During this project, we have conducted a series of controlled CO2 release experiments to assess the performance of different sensor technologies in different environments. In 2018 we conducted laboratory tests over several weeks to evaluate the capabilities of relevant chemical sensors in a controlled environment. In the fall of 2018 we conducted an 8-week long field trial in a sheltered area of the Oslo fjord to further study the capabilities and limitations of chemical as well as acoustic sensors in a more realistic environment. This report describes the second and final round of nearshore controlled release experiments conducted in the spring of 2019, also in the Oslo fjord but in deeper water and ocean conditions similar to the North Sea environment. ...
