Biomethane Could Anchor Grid Reliability for Oahu
Analysis shows a small strategic biomethane reserve could provide critical grid reliability backup for Oahu's fully electrified renewable energy system during extended low-generation events.
Key Takeaways
- Biomethane from organic waste could provide 3-5 day grid reliability reserve for Oahu's isolated renewable grid
- More cost-effective than massive battery overbuild for multi-day low-generation weather events
- Carbon-neutral lifecycle since biomethane carbon comes from recently captured atmospheric CO2
