| Check | Carbon capture and storage | Renewable hydrogen fuel |
|---|---|---|
| System change | Separate carbon dioxide from a process or combustion stream, condition it, transport it and store it under an approved system. | Use hydrogen produced under a defined production and electricity boundary in suitable equipment. |
| Evidence required | Stream flow and composition, capture rate, energy demand, transport route, storage availability, monitoring and regulatory approvals. | Hydrogen specification, production route, certification, delivered cost, storage, burner limits, safety case and nitrogen-oxide control. |
| Principal constraint | Capture percentage is not the same as net lifecycle reduction. Include additional energy and the full chain. | Do not describe hydrogen as zero-emission without stating the production and reporting boundary. |
| Technical source | International Energy Agency CCUS overview | US Department of Energy hydrogen resources |
Select a measure only after a site-specific energy balance, cost estimate, operational review and verification plan.

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.
