Motivationfor Offshore Hydrogen


INTERNAL


7.5 GW installed (status: 31.12.2019) 15 GW by 2030 (announced: extension to 20 GW) Overall potential up to 70 GW

Today Site Development Plant 2019 Remaining area

INTERNALPower excess area

H2 potential consumption


Case Study: 400 MW Offshore Production Platform


INTERNAL

• Centralized vs. decentralized production

• Retrofitting existing platforms vs. newbuilt platform

• Floating platform vs. bottom-fixed installation

• Small vs. large-scale

• Hydrogen transport via pipeline or tank vessel

Today: Electrical Connection To Onshore Grid (Via HVAC Or HVDC)


INTERNAL

• Today: electrical connection to onshoregrid (via HVAC or HVDC)

• Future: electrical and / or gas-based gridconnection of offshore wind farms

• Benchmarking:

o 100% Offshore Electrolysiso Hybrid Offshore Case

(Electricity & H2)o 100% Onshore Electrolysis


INTERNAL


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.
