Inzonex removable modular insulation on industrial equipment
Cut the tonnes at the source

Hot industrial equipment? Cut the heat loss.

Boilers, kilns, heat exchangers, valves and steam lines lose energy continuously. Inzonex makes Inzonex Modular Insulation — snap-fastened modules engineered per temperature tier, not generic off-the-shelf jackets:

  • Up to 96% less heat loss from insulated surfaces
  • Surface temperature ≤45 °C — touch-safe for workers (EN ISO 13732-1)
  • 6× faster maintenance access vs standard insulation jackets and metal cladding/boxes — unclips and refits in minutes, no destruction
  • Inspectable — opens for corrosion-under-insulation checks, then refits like-new (generic jackets often don't survive removal)
  • Typical payback under 2 years — some sites 9–11 months
See Inzonex process-equipment insulation →Run the savings study

Every tonne you stop emitting is a tonne you don't have to report: cutting heat loss is a measurable, auditable Scope 1 reduction that flows straight into EU ETS, CBAM and your ESG / CSRD disclosures — not an offset, an actual emission cut.

Use your own site assumptions

Turn the public benchmark into a plant estimate by changing the assumptions engineers already know.

Calculation basis

Fuel €/t steam = (0.679 MWh/t ÷ η) × gas €/MWh
CO₂ €/t steam = (0.679 MWh/t ÷ η) × 0.202 tCO₂/MWh × EUA €/tCO₂
Annual steam cost = (fuel + CO₂) × steam t/h × hours/year
Heat-loss cost = heat-loss kW × hours/year × gas €/MWh ÷ η ÷ 1000
Default thermodynamic basis: saturated steam at 10 bar(g), feedwater 80 °C, 0.679 MWh/t enthalpy rise. Change pressure, feedwater temperature, efficiency or hours for a site estimate.

Workload modes

Start from the way a plant thinks about steam: tonnes of linen, brewhouse load, boiler output or operating hours.

Industrial laundry

Use boiler load or measured steam. Example below uses 5 t/h steam for 6,000 h/year.

FAQ

Questions

How much does steam cost per tonne?
In 2025 H2, producing one tonne of saturated steam from natural gas costs roughly €20–€82 in fuel across this index — for example €55/t in Germany — plus about €12/t of CO₂ cost for EU ETS installations at the current allowance price.
What is the formula for steam cost?
Steam cost in €/t = gas price in €/MWh × 0.77 MWh fuel per tonne (0.679 MWh of enthalpy at 88% boiler efficiency), plus the carbon component where applicable.
Why does steam cost differ between countries?
The main driver is the industrial gas price: Sweden is €106.5/MWh while Georgia is €26.2/MWh in the current dataset. Carbon pricing widens the gap for ETS-covered sites.
How often is this index updated?
Gas prices follow Eurostat's semi-annual releases. The CO₂ component uses the dated EUA value from the Carbon Hub feed and can be refreshed independently.
Is the CSV free to use?
Yes. Download the CSV and reuse it with attribution to inzonex.co.uk/carbon/steam-cost-index/. The table, CSV and calculator use the same calculation basis.
How this page is built: industrial gas prices from Eurostat nrg_pc_203 (band 10,000–99,999 GJ, excl. VAT) × steam-table enthalpy at the stated boiler efficiency; CO₂ at the EU ETS allowance price.

From benchmark to your site

Use this index to see where a tonne of steam — and each kilowatt of standing heat loss — costs most across Europe, then estimate the impact of reducing losses on boilers, steam lines, valves and hot equipment using your own site assumptions.
