Hydrogen fuel switch

Burning green hydrogen in boilers/furnaces eliminates combustion CO2 — at a fuel price that still needs subsidy or carbon prices well above today's to clear.

How it works

Mechanism & sizing

Use cases that pencil first: H2-ready equipment at natural replacement, blending where pipelines deliver it, processes needing flame (not heat-pump-able). For most plants pre-2030: buy H2-readiness cheaply at equipment renewal, spend the money on efficiency now.

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 90% 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 under 2 years (some 9–11 months)

FAQ

Hydrogen fuel switch, answered

What does green hydrogen cost as fuel?
Several times natural gas per MWh as of 2026 — the gap IS the carbon-price trajectory debate. Watch national H2-bank auctions for real numbers.
What is H2-ready equipment?
Burners/turbines certified for stated H2 blends (often 20-50%, some 100%) — a cheap option to buy at replacement, expensive to retrofit later.
Hydrogen or heat pump?
Below ~200 °C the heat pump usually wins on physics (COP>1 vs combustion). Hydrogen's lane is high-temperature flame and existing gas infrastructure.
