Decarbonizing power — gas (ccgt): the honest pathway

Gas power pays full carbon price from day one — no free allocation, ever. At €77/t that's ≈€28/MWh inside the EU: carbon is now a fuel-sized line item, which puts heat rate back at the centre of plant economics.

Cost exposure

What one MWh carries, 2026 → 2034

Year	Free allocation (EU)	Payable carbon cost	Annual bill (per 1,000,000 MWh)
2026	97.5%	€0.72 / MWh	€715,950
2030	51.5%	€13.89 / MWh	€13,889,430
2034	0.0%	€28.64 / MWh	€28,638,000

At EUA €77.4 (11 Jun 2026) and ≈0.37 t CO2/MWh at 55-60% efficiency (full ETS exposure). EU ETS industry schedule; exporters under CBAM follow the mirrored phase-in. Power sectors pay 100% from day one.

Reduction measures for power — gas (ccgt)

Heat-rate recovery: inlet cooling, compressor wash, insulation−2%

HRSG optimisation & attemperation discipline−1%

Hydrogen co-firing readiness−50%

CCS post-combustion−90%

Flexible operation for renewable-heavy grids−0%

Indicative reduction potential of each measure against the relevant emissions share (sources: IEA industry roadmaps, sector associations — see each measure page). Measures stack but don't simply add.

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 patented (UK GB2508992.1) removable modular insulation — snap-fastened covers 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 than fixed cut-and-weld lagging — unclips and refits in minutes, no destruction
Inspectable — comes off to check for corrosion under insulation, then refits like-new (generic jackets often don't survive removal)
Typical payback up to 2 years

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.

The fast tonnes

Heat losses you can cut this budget year

Our CCGT/HRSG heat-rate calculator is built exactly for this: HRSG casing, valves and steam-side losses converted into heat-rate and €/yr. On a 2 GW site, 0.1% of heat rate is real money even before the carbon term — with it, efficiency projects screened at €30/t deserve a re-run.

Method: ASTM C680 / ISO 12241 surface energy balance — the same engine as our public calculators. Typical removable-insulation effect across hot-process plants: 2–5% of fuel-related CO2, payback up to 2 years.

FAQ

Power — gas (CCGT) & carbon, answered

Why does a CCGT care about €77/t more than industry does?

Power gets zero free allocation — the full price lands on every MWh from day one: ≈€28/MWh at current EUA, often the second-largest cost after fuel.

What CO2 does insulation save on a power plant?

Heat-rate basis: recovered HRSG/steam-side losses improve heat rate fractions of a percent — small in %, large in absolute fuel+carbon on baseload hours.

Is hydrogen co-firing real?

Most new turbines are 30-50% H2-capable; economics wait on hydrogen supply. Heat-rate efficiency pays regardless of which fuel future arrives.

How this page is built: heat-loss figures follow ASTM C680 / ISO 12241 (the method behind our public calculators); facility emissions from Climate TRACE & EU ETS verified data across 30,000+ industrial sites; the 2026–2034 schedule is Regulation (EU) 2023/956, not a forecast.
