StorageStack Decisions
A procurement decision tool for utility-scale and data-center storage planners that compares sodium-ion, LFP, and flow batteries on a 20-year total-cost basis using your specific climate, cycling profile, and discharge curve — not vendor brochure numbers.
Energy storage procurement leads at investor-owned utilities and hyperscale data center operators
- Site-specific TCO model that pulls your NOAA climate data and penalizes chemistries that need active cooling in hot sites
- Chemistry scorecard updated monthly from independent test data (not vendor PR) on cycle life, degradation, and safety incidents
- 'AI workload' preset for data centers that values round-trip efficiency and 24/7 cycling; separate 'solar smoothing' preset for utilities
- RFP generator that exports your weighted scorecard into a vendor questionnaire you can actually send
GM backing Peak Energy means sodium-ion is now a real two-horse race against LFP in the U.S., and the article explicitly shows incumbents fail because they can't match LFP on price-per-cell — buyers need an independent model that captures the 20-year total-cost case Peak is making.
GM/Peak partnership (June 2026) and GM Ventures strategic investment confirm sodium-ion is now a real procurement option vs LFP; multiple industry sources flag the LCOS comparison as the make-or-break decision for BESS buyers in 2025-2026.Peak and GM Partner to Scale Next-Generation Energy Storage Technology ↗GM Backs Sodium Ion Batteries for U.S. Grid Storage ↗
Market is already served by Wood Mackenzie Lens, BloombergNEF NEO, Aranca's calculator, and a wave of consultancies/Substack-style guides (jisenergy, sdvguru, battery.mba, howtostoreelectricity) doing exactly this chemistry-vs-chemistry LCOS writeup, leaving narrow SaaS whitespace against high-end data subscriptions.Energy Storage Market Data & Forecasts | Lens | Wood Mackenzie ↗Energy Storage Cost Calculator - aranca.com ↗
Hyperscalers and IOUs do pay for storage analytics via $15-50k/yr data subscriptions and bespoke consulting, but the buying group is small and sales cycles are long; no evidence yet of standalone SaaS at meaningful ACV in this niche.US Energy Storage Monitor | Wood Mackenzie ↗LCOS Calculator | Levelized Cost of Storage Analysis Tool ↗
BESS procurement decisions for utility and hyperscale buyers will remain a multi-decade problem tied to the energy transition and AI data-center load growth; 20-year TCO framing stays relevant.Peak Energy, GM partner to scale domestic sodium-ion battery supplies ↗
Public climate, cycling profile, and round-trip efficiency data plus vendor specs are sufficient to build a defensible 20-year LCOS model, but accurate cell-level degradation curves for sodium-ion are scarce and need primary-research or licensing to validate.Sodium-Ion vs LFP BESS LCOS: A Complete Technoeconomic Analysis ↗
