| Check | Biogas or biomass fuel use | Renewable hydrogen fuel |
|---|---|---|
| System change | Use a qualifying biological feedstock to displace another energy source. | Use hydrogen produced under a defined production and electricity boundary in suitable equipment. |
| Evidence required | Feedstock quantity and quality, lifecycle boundary, sustainability evidence, storage, emissions controls and conversion efficiency. | Hydrogen specification, production route, certification, delivered cost, storage, burner limits, safety case and nitrogen-oxide control. |
| Principal constraint | Biogenic origin does not remove lifecycle, air-quality, permitting or sustainability requirements. | Do not describe hydrogen as zero-emission without stating the production and reporting boundary. |
| Technical source | US Environmental Protection Agency AgSTAR | 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.
