Accomplishment: NREL-TNO OSW-H2
Reducing costs and uncertainty
Main potential cost reductions through innovation:
-
-
In-turbine electrolysis: process intensification via turbine-electrolyzer integration
Electrolyzer: R&D on stack level to increase durability/reliability and reduce
footprint and cost
Modularization / standardization of modules
• Main uncertainties:
-
-
-
• Pilots and demonstrations will be key
for reducing uncertainty
Additional CAPEX due to offshore (unmanned) operations, including e.g.
additional equipment and reliability/redundancy
O&M costs for electrolysis, to model offshore ramifications and optimize
between system design and operation considerations.
Uncertainties in dynamic operation to understand operational performance
window (effect of running above nominal load, at min load, cold start, hot start
etc); degradation and optimized dispatch
BoP requirements for the electrolysis system to understand the trade-off
between reliability and flexibility
- Turn down rate or minimum load is very important uncertainty affecting the
design. Differs per technology.
