Hydrogen research
The right energy.
At the right time.
Carbon-aware operation converts electricity variability into an operating decision.

Published scenarios
Three ways to operate.
| Scenario | Operating rule | Monthly CO2 per site |
|---|---|---|
| Baseline | Fixed production at 20 kg/h | 30–500 metric tons |
| Variable 1 | Tiered curtailment as grid carbon rises | 30–110 metric tons |
| Variable 2 | Produce only below 0.6 kg CO2/kg H2 | 0.1–0.6 metric tonsTasmania |
Ranges depend on state and month. Variable 2 qualifies for hydrogen tax credits in the published scenario. The scenario threshold in kg CO2/kg H2 is distinct from the grid-carbon threshold in gCO2/kWh shown above.

The architecture
behind the analysis.
Model-based systems engineering and hetero-functional graph theory bring system structure into spatio-temporal life cycle analysis.
