Summer School

I august afholder vi sommerskole, hvor du kan blive klogere på offshore-teknologier. Hold dig opdateret på siden for information om den kommende sommerskole.

Summer School

Summer School 2021

Da sommerskolen blev afholdt på engelsk, er følgende information kun tilgængeligt på engelsk. 

The Summer School took place on 16-27 August at DTU Lyngby.

The Summer School was divided into two weeks:

Week 1 (16-20 August) -  CO2 storage in subsurface
Week 2 (23-27 August) - Produced water management

The goal of the school was to provide the participants with a deep understanding on selected topics in CO2 storage and Produced Water Management and their associated challenges and opportunities.
