Case Studies
This page presents OCEAN-H2 case studies as structured project narratives: a defined challenge, a transparent analytical or experimental approach,
and clearly stated outputs. Each case study is designed to be readable by both technical and non-technical audiences, while keeping the underlying
assumptions and boundaries explicit.
How to read our case studies
Each case study is organised using a consistent logic so that comparisons are meaningful across sites, technologies, and scenarios.
The goal is to avoid “pretty stories” and instead provide traceable, decision-relevant evidence.
- Context: what system is being examined and why it matters for offshore green hydrogen.
- Approach: the modelling, data, and evaluation steps used (including sensitivities where relevant).
- Outputs: the concrete deliverables, datasets, figures, and key messages suitable for stakeholders.
Case study portfolio
Energy Resource Integration
Studies in this group focus on how offshore renewable resources can be combined and managed to supply stable power to hydrogen production systems,
including the implications of variability, curtailment, and power quality constraints.
Hydrogen Production and Storage
These case studies examine techno-operational choices across the hydrogen chain, including electrolyser operating regimes, buffer storage sizing,
and strategies that balance efficiency, reliability, and system cost.
Impact, Safety, and Governance
This set addresses the “real-world” layer: marine constraints, permitting logic, safety framing, and stakeholder interfaces.
The intent is to connect engineering decisions to feasible deployment pathways.
Featured case study formats
The following formats are used throughout OCEAN-H2 to keep case studies comparable and to support dissemination in a standard, auditable way.
Format A: Problem → Method → Evidence → Implications
- Problem: what needs to be solved and what constraints exist.
- Method: data sources, modelling assumptions, and evaluation approach.
- Evidence: results, sensitivity ranges, and limits of validity.
- Implications: what the result means for design, cost, and deployment.
Format B: Scenario book (baseline + sensitivities)
A baseline scenario is defined first, followed by sensitivity variants (for example resource profile, operating strategy, storage, and grid interface).
This format is used when conclusions depend strongly on uncertain parameters.
- Baseline: consistent assumptions and reference configuration.
- Sensitivities: controlled parameter shifts with traceable impacts.
- Comparison: what changes, what stays robust, and what remains uncertain.
What you will find here over time
As the project progresses, this page becomes the public index of validated case studies. Each case study will include a concise technical summary and links to
related public outputs when available. The structure is designed to keep descriptions consistent and comparison-ready across the portfolio.
