Telecom tower backup

Backup power for telecom towers.

20-year levelised cost of backup power at a telecom tower: a diesel generator against an H2C0 hydrogen fuel cell, each with a lead-acid battery bank. Compare operating profiles, grid and hydrogen prices, the breakeven point and carbon.

LCOE methodology · Umagine Hydrogen (UHPL)

LCOE = NPV(total costs) ÷ NPV(energy delivered), at a 10% discount rate over 20 years.

DG costs: CAPEX + diesel + grid charging + maintenance (₹18 per running hour) + logistics (scaled by DG usage) + overhauls (₹50,000 per 12,000 h) + battery replacements in years 5, 10 and 15.

FC costs: CAPEX + H₂ fuel + grid charging + O&M (2% of FC CAPEX, 1% of battery CAPEX a year) + stack replacement in year 10 at 50% of FC CAPEX + battery replacements in years 5, 10 and 15.

Carbon-adjusted LCOE: base LCOE − (annual CO₂ saved × carbon price ÷ annual energy), discounted the same way.
