The Multi-criteria Analysis Dashboard lets you explore and compare multiple water, energy, and hydrogen indicators simultaneously across regions and scenarios. Interactive visualizations support the assessment of regional performance and trade-offs among key variables relevant for hydrogen development.
The Multi-criteria Analysis Dashboard includes the following indicators and features:
- Cluster classification [-]. Regions are grouped into four suitability clusters—High, Medium-high, Medium-low, and Low—based on the combined assessment of water availability and renewable energy production.
- Water Exploitation Index Plus (WEI+) [%] – yearly average. This index measures the percentage ratio between total water consumption for domestic, agricultural, and industrial uses to the available water resources.
- Aridity Index (AI) [-] – yearly average. This climate classification index measures the ratio of precipitation to potential evapotranspiration, indicating the degree of dryness of a region.
- Standardized Precipitation Index (SPI-12) [months per year] – yearly average. This index is based on 12-month cumulative precipitation and identifies long-term drought and water surplus conditions, normalized to local historical climatology. The two aggregations report the average number of very dry months (SPI-12 < −1.5) and very wet months (SPI-12 > 1.5) over the selected time period.
- Renewable energy production [GWh/year] – yearly value. This indicator represents the electricity generation from hydropower, solar and wind.
- Potential hydrogen production [kt H₂/year]. Planned and potential hydrogen production capacity is displayed and overlaid on the cluster map to highlight spatial patterns and regional development opportunities.
Temporal time frames considered:
- current scenario, corresponding to the most recent period for which data are available from the selected sources.
- reference future scenario, corresponding to the SSP3-7.0 defined in the IPCC Sixth Assessment Report. It represents a “regional rivalry” pathway characterized by fragmented governance, limited international cooperation, and slow technological diffusion. Emissions remain high throughout the century, making this scenario broadly consistent with a continuation of current policy trends and close to a business-as-usual trajectory.
- pessimistic future scenario, corresponding to the SSP5-8.5 defined in the IPCC Sixth Assessment Report. It represents a fossil-fuel-driven development pathway with very high energy demand and minimal mitigation efforts, and is commonly used as a worst-case or high-end reference scenario to explore upper-bound climate risks.
