| Check | Removable insulation | Renewable hydrogen fuel |
|---|---|---|
| System change | Reduce heat transfer from exposed valves, flanges, fittings and equipment while retaining maintenance access. | Use hydrogen produced under a defined production and electricity boundary in suitable equipment. |
| Evidence required | Surface inventory, external geometry, temperature, ambient conditions, operating hours, insulation construction and coverage boundary. | Hydrogen specification, production route, certification, delivered cost, storage, burner limits, safety case and nitrogen-oxide control. |
| Principal constraint | An omitted hot surface, inaccessible joint or unsuitable construction changes the result and the maintenance outcome. | Do not describe hydrogen as zero-emission without stating the production and reporting boundary. |

Select a measure only after a site-specific energy balance, cost estimate, operational review and verification plan.
Read Removable insulation · Read Renewable hydrogen fuel
Use measured surface area, temperature and operating hours to calculate heat loss from boilers, kilns, heat exchangers, valves and pipework. Inzonex supplies removable modular insulation for equipment that requires maintenance access.
Do not add a calculated reduction to an emissions report until the reporting boundary, factor, implementation date and verification method have been approved.
