CopenHydrogen - Power balancing and storage I

The more fluctuating renewable energy from the sun, wind and water being introduced in our energy system, the greater will be the need to store energy for shorter or longer periods of time. With hydrogen, renewable energy can be stored for longer periods of time.

The project partners wish to demonstrate grid balancing and energy storage using hydrogen and fuel cell technologies in interaction with electricity, heat and gas supply in MW scale with key technology providers and utilities. Once essential technologies such as large electrolyzers and fuel cells (both >1MW effect), hydrogen storage, interaction between these and the existing infrastructure have been demonstrated they will be proven technologies to the global market. The demonstration effort will aim both at bringing the technical risks down to a minimum and at serving as showcase to customers of each of the partners.

The City of Copenhagen will serve as the demonstration host and is heavily involved in the promotion of the technologies, as they fit perfectly with Copenhagen's target to be CO2 neutral by 2025. The financial implications for this demonstration are huge, both with respect to investments in demonstration versions of the technologies and the required modification of especially the district heating system and the power supply. Hence, the project consortium has decided to divide the effort into three phases.

Phase I of the project will provide solid and detailed analyses for investment decisions, both on a project level and for each partner. Also the economy in the operation must be better understood.

DTU is work package leader responsible for the technology preparations.
