CASE 1
Accomplishment: NREL-TNO OSW-H2 Case
Distributed in-turbine electrolysis
Necessity of additional
compression and storage
beyond turbine level for inter-
array and export pipeline
Infield design of pipelines and
collection not designed or
optimized
·
O&M requirements for
distributed electrolysis unclear
•
.
Uncertainties
CASE 2
Centralized offshore platform
Platform size and cost is a
big uncertainty and major
contribution (footprint and
weight of electrolysis system)
Optimization of windfarm size
to electrolyzer capacity not
performed
Installation and O&M costs
uncertain (also Case 1)
•
CASE 3
Onshore electrolysis
• Grid connection not
considered, but is factor in
optimal sizing and operation
Buffer storage dependant on
demand scenario (offshore-
case 1&2- may be able to
use inherent pipeline storage
or inexpensive undersea
storage)
Trade-off between CapEX and OPEX for offshore operation not optimized.
More uncertainty for system design offshore.
