29 Co-product reduction of emissions for electrolysis production pathway

(1) The amount by which the emissions for the production of a batch of hydrogen in accordance with the electrolysis production pathway may be reduced, EO2sale,b, in kilograms of CO2-e is worked out using the following formula:

Start formula E start subscript O2sale,b end subscript equals 7.5 % times R start subscript O2sale,b end subscript times E start subscript minM,b end subscript end formula

where:

RO2sale,b is either:

(a) if the percentage worked out in accordance with subsection (2) is less than 100%—that percentage;
(a) in any other case—100%.

Note: R02sale,b represents the ratio of oxygen sold compared to oxygen produced in the batch.

EminM,b is the emissions for the electrolysis production module for the batch (b) in kilograms of CO2-e.

Note: 7.5% represents the portion of emissions from a kilogram of hydrogen produced by electrolysis that is attributable to a kilogram of oxygen sold.

(2) For paragraph (a) of the definition of RO2sale,b in subsection (1), RO2sale,b is worked out using the following formula:

Start formula R start subscript O2sale,b end subscript equals start fraction S start subscript O2 end subscript over 7.94 times Q start subscript pathway,b end subscript end fraction end formula

where:

SO2 is the quantity of oxygen in kilograms produced in the course of producing a batch (b) of hydrogen in accordance with the electrolysis production pathway that has been sold:

(a) by the holder of the production profile to another person; and
(b) for an amount that is not less than its market value at the time of sale.

Qpathway,b is either:

(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—the quantity of product in kilograms:
(i) measured after the minimum production module has been completed, but before the intermediate storage tank production module has commenced, in relation to the product; and
(ii) measured and monitored in accordance with section 9; or
(b) in any other case—the amount of hydrogen in the batch (b) in kilograms worked out in accordance with section 24.

Note: 7.94 is the kilograms of oxygen produced per kilogram of hydrogen produced by electrolysis.
