30 Production emissions intensity—hydrogen
(1) The emissions intensity for the production of a batch of hydrogen, EI,b, is worked out: (a) if the intermediate storage tank production module is used to produce the batch (b) and the duration of the batch period is less than the time it took to fill the vessel for the purpose of the module—in accordance with subsection (2); and (b) in any other case—in accordance with subsection (5).
Note: The production emissions intensity for the batch must be included on the PGO certificate in accordance with the rules.
(2) For paragraph (1)(a), EI,b is worked out: (a) if the value of Qpathway,b is equal to or greater than the value of Qb—in accordance with subsection (3); and (b) if the value of Qpathway,b is less than the value of Qb—in accordance with subsection (4). (3) For paragraph (2)(a), EIb is worked out using the following formula:
Start formula EI start subscript b end subscript equals start fraction E start subscript pathway,b end subscript over Q start subscript pathway,b end subscript end fraction end formula
where:
Epathway,b is the emissions attributable to the batch (b) in kilograms of CO2-e, worked out in accordance with section 27.
Qpathway,b has the meaning given by subsection (6).
(4) For paragraph (2)(b), EIb is worked out using the following formula:
Start formula EI start subscript b end subscript equals start fraction E start subscript pathway,b end subscript plus open bracket Q start subscript b end subscript minus Q start subscript pathway,b end subscript close bracket times EI start subscript b minus 1 end subscript over Q start subscript b end subscript end fraction end formula
where:
Epathway,b is the emissions for the production of the batch (b) in kilograms of CO2-e, worked out in accordance with section 27.
Qpathway,b has the meaning given by subsection (6).
Qb has the meaning given by subsection (6).
EIb-1 is:
(a) if the batch is the first batch of the product produced by the holder of the production profile —worked out in accordance with subsection (3); or
(b) in any other case—the production emissions intensity for the batch produced by the holder of the production profile immediately prior to the batch (b) in kilograms of CO2\-e per kilogram.
