Lighthouse project: technology evaluation (use-case for power-to-H2) for a DSO
Partners: ETHZ (FEN), EW Höfe
Duration: 2019
Funding: EW Höfe
Project Leader: FEN
Project Team: Dr. Alexander Fuchs
Interactive tool demonstrating the results
- Identification and comparison of relevant technology options (BESS, Power-to-hydrogen, Power-to-methane and combinations thereof)
- Assessment of the overall value (i.e. societal and economic) and feasibility of the individual technology options
- Optimal sizing based on DSO's requirements/priorities
- Synthesis, investment analysis and recommendation
- Investment decision support for local Swiss utility for flexible technology options (storage and/or sector coupling)
- Can existing substation infrastructure (e.g. land, transformer etc.) be utilized as a flagship project to enable the objectives of "Energy Strategy 2050"?
- Uncertainty about long-term sustainability and economic case of the investment
- Time-series analysis of different operational scenarios
- Calculation of investment indicators
- Development of interactive web-tool for sensitivity analysis
- Result: Strong economic use case for hydrogen production in combination with BESS

Combined power demand at substation over one day with local demand, hydrogen production and BESS.
