Cost reduction of offshore grid connection
Reduction of grid reinforcement cost in onshore transmission grid
Avoiding curtailment & redispatch measures
Lower hydrogen production cost (LCOH) compared to onshore
Extension of development plan for Offshore Wind Energy
In 2018 alone 1.4 TWh electricity from Offshore Wind was curtailed: enough to produce 28 Mio. kg hydrogen
Expensive long-distance offshore grid connection (up to 25% of electricity costs)
Cost advantages increases with offshore distance (up to 20%*)
* Depending on project specifics
INTERNAL
The case-study delivers the following results:
Technical and economic feasibility of a 400 MW offshore platform.
Cost-advantage for offshore hydrogen production.
Efficiency improvement for the energy system with hydrogen production
Conclusion
Offshore hydrogen production has the potential tochange the future utilization of Offshore Wind Energy.
