Storage mode — Zero Cooling Cost / Island Mode

Autonomous cooling, costs near zero.

When a DHC network is not there or contracting one does not make sense, thermal storage makes you independent. Capture the heat, store it, manage it in the convenient hours. And in a blackout the cooling does not stop.

~€1M/year
Electricity savings from PUE 1.12 → 1.01
Cooling-battery CAPEX avoided (Thermal UPS included)
DC bus 800V
Native architecture, compatible with high-density AI racks
Payback (IRR ~30%)

Reference: 10 MW IT data center, 150 kW per rack.

The problem

You are far from district heating. Or you want to stay free of external contracts.

Energy for cooling remains the data center's first operating cost, and with AI densities it grows non-linearly. Thermal loads are not uniform: daytime peaks, underused night-time hours.

Without a buffer you cannot shift demand in time, so you pay everything at peak price. And on cooling, blackout risk stays exposed: no UPS protects the data center's most critical asset.

You need autonomy. Technological, contractual, operational.

The solution

Three economic levers, one machine.

RHP coupled with a thermal buffer (tanks or PCM): captures excess heat, stores it, releases it during the convenient hours. Thermal peak shaving without touching the IT loads. In parallel, Thermal UPS: continuous cooling even in a blackout. The platform is DC-native, compatible with the 800V bus of high-density AI racks: you eliminate the double AC/DC conversion, reduce Joule losses, simplify the electrical distribution.

01

Electricity savings

PUE from 1.12 to 1.01, with auxiliaries self-powered via ORC.

02

Avoided CAPEX

No traditional cooling batteries: Thermal UPS already built in.

03

Reduced conversion losses

DC-native architecture, native integration with the 800V bus.

04

Future-ready

If tomorrow a DHC network reaches you, you are already ready to connect.

The numbers

What changes, in figures.

Reference: 10 MW IT data center, 150 kW per rack.

Electricity savings (PUE 1.12 → 1.01)~€1M/year
Cooling-battery CAPEX avoided~€900K
ORC electricity self-consumed2,356 MWh/year
DC bus 800VNative compatibility
Water consumption<2 m³/year
CO₂ avoided18,200 tCO₂/year
Payback3.1 years
Customer IRR~30%

Waste heat remains available for a future DHC connection, with no additional structural work.

When this does NOT fit

When this solution is not the right choice.

Storage mode does not make sense in these cases. We tell you upfront, before you book the call.

  • You do not have enough external footprint for the storage tanks (significant ground space)
  • Your CAPEX budget is capped at zero (consider EaaS mode)
  • You already have a DHC network within 2 km (DHC mode adds direct revenue from heat sale)
  • The 800V DC bus advantage only pays off in full with compatible power infrastructure

In those cases: consider RHP for DHC for direct revenue, or Energy as a Service for zero CAPEX.

Proof

Validated technology. Ready to scale.

Pilot plant operational since June 2026 on the base technology (small-scale Carnot battery). Measured performance exceeds expectations on COP and heat recovery.

Reversible ORC patent filed October 2025. Co-inventors: Marco Margotti (CEO, 20 years B2B + 6 years on ORC Kaymacor) and Giuseppe Toniato (CTO, 30 years of thermodynamic systems).

The technology is validated. We are ready to bring it to commercial plants up to 10 MW IT and beyond.
