Section 95114 - Hydrogen ProductionThe operator of a facility who is required to report under section 95101 of this article, and who is not eligible for abbreviated reporting under section 95103(a), must comply with Subpart P of 40 CFR Part 98 (40 CFR §§ 98.160 to 98.168) in reporting emissions and other data from molecular hydrogen production to ARB, except as otherwise provided in this section. GHG emissions and output associated with hydrogen production must be reported separately from other emissions and output associated with a petroleum refinery.
(a)Definition of Source Category. This source category is defined consistent with 40 CFR § 98.160(b) and(c). This category is further defined as a hydrogen production source that produces molecular hydrogen whether sold to other entities or consumed on-site.(b) CO2from Fossil Fuel Combustion. When calculating CO2 emissions from fuel combustion under subpart C as specified at 40 CFR § 98.162(b)-(c), the operator must use a method in 40 CFR § 98.33(a)(1) to § 98.33(a)(4) as specified by fuel type in section 95115 of this article.(c)Monitoring, Data and Records. For each emissions calculation method chosen under section 95114(b), the operator must meet the applicable requirements for monitoring, missing data procedures, data reporting, and records retention that are specified in 40 CFR § 98.34 to § 98.37, except as modified in sections 95114(h), 95115, and 95129 of this article.(d) CO2Emissions from Hydrogen Production Units. When calculating CO2 emissions from hydrogen production units under the fuel and feedstock material balance approach specified at 40 CFR § 98.163(b), the operator must apply the weighted average carbon content values (the term CCn in Equations P-1 through P-3) and, for gaseous fuels and feedstocks, the weighted average molecular weight values obtained according to the frequencies specified in section 95114(e)(2).(e)Fuel and Feedstock Contents. For each hydrogen production unit, operators must report the following information:(1) When monitoring GHG emissions with a CEMS as specified in 40 CFR § 98.163(a), the operator must report the monthly carbon content, atomic hydrogen content (excluding hydrogen atoms contained in steam), and molecular hydrogen content for each feedstock. The reported values must be weighted averages from the results of one or more analyses per month.(2) When monitoring GHG emissions without a CEMS as specified in 40 CFR § 98.163(b), the operator must report the monthly weighted average atomic hydrogen content (excluding hydrogen atoms contained in steam) and weighted average molecular hydrogen content for each feedstock from the results of one or more analyses per month. The operator must also report the monthly carbon content for each fuel and feedstock, and the molecular weight for each gaseous fuel and feedstock as follows: (A) The reported values must be weighted averages from the results of one or more analyses per month for natural gas or standardized materials specified in Table 2-3 of section 95115.(B) The reported values must be weighted averages from the results of daily sampling for each month for nonstandard materials not specified in Table 2-3 of section 95115, such as refinery fuel gas. For liquid and solid fuels and feedstocks, daily samples may be combined to generate a monthly composite sample for carbon content analysis.(f)Weighted Average Sampling. Where this section requires sampling of a parameter on a more frequent basis than 40 CFR Part 98 , the operator or supplier must comply with the following: (1) The samples must be spaced apart as evenly as possible over time, taking into account the operating schedule of the relevant unit or facility.(2) The operator or supplier must calculate and report a weighted average of the values derived from the samples by using the following formula: Click here to view image
Where:
VE = The value of the parameter to be reported under 40 C.F.R. Part 98 for period E.
j = Each period during period E for which a sample is required by this article.
n = The number of periods j in period E.
Vj = The value of the sample for period j.
Mj = The mass of the sampled material processed or otherwise used by the relevant unit or facility in period j.
(3) The operator or supplier must keep records of the date and result for each sample or composite sample and mass measurement used in the equation above and of the calculation of each weighted average included in the emissions data report, pursuant to the record keeping requirements of section 95105.(g)Data Reporting Requirements. When reporting data as specified in 40 CFR § 98.166, the operator must also report the mass of carbon and methane for which GHG emissions are calculated and reported by the facility using other calculation methods provided in this regulation (e.g., carbon in waste diverted to a fuel system or flare, where the CO2 and CH4 emissions are calculated and reported using other methods specified in this regulation). To avoid double-counting, these emissions must be subtracted from the total facility emissions.(h)Missing Data Substitution Procedures. The operator must comply with 40 CFR § 98.165 when substituting for missing data, except for 2013 and later emissions data reports as otherwise provided in paragraphs (1)-(2) below. (1) To substitute for missing data for emissions reported under section 95115 of this article (stationary combustion units and units using continuous emissions monitoring systems), the operator must follow the requirements of section 95129 of this article.(2) For all other data required for emissions calculations in this section, the operator must follow the requirements of paragraphs (A)-(C) below.(A) If the analytical data capture rate is at least 90 percent for the data year, the operator must substitute for each missing value using the best available estimate of the parameter, based on all available process data.(B) If the analytical data capture rate is at least 80 percent but not at least 90 percent for the data year, the operator must substitute for each missing value with the highest quality assured value recorded for the parameter during the given data year, as well as the two previous data years.(C) If the analytical data capture rate is less than 80 percent for the data year, the operator must substitute for each missing value with the highest quality assured value recorded for the parameter in all records kept according to section 95105(a).(i)Transferred CO2. The operator must calculate and report the mass of all CO2 captured, transferred off-site, and reported by the hydrogen production facility as a supplier of CO2 using reporting provisions found in section 95123. Refineries and hydrogen production facilities must subtract this reported mass of CO2 that is captured and sold or transferred off-site from their facility emissions report to avoid double counting.(j)Additional Product Data. Operators must report the total annual mass of on-purpose and by-product gaseous hydrogen produced (metric tons) and total annual mass of liquid hydrogen sold (metric tons). Operators must separately report all gaseous and all liquid hydrogen sold or otherwise transferred (metric tons) to petroleum refineries and hydrogen vehicle fueling stations and include the name of the purchaser (or receiver) and the quantity sold or transferred to each facility or entity. Operators must also specify if the hydrogen plant is an integrated refinery operation. Hydrogen plants integrated in refinery operations must also report any sales or transfers of hydrogen as specified in this subsection.(k)Methane and nitrous oxide emissions from stationary combustion. Operators must calculate and report fuel high heat value (in units of MMBtu/kg, MMBtu/scf, or MMBtu/gallon for solid, gaseous, or liquid fuels respectively), and CH4 and N2O from fuel stationary combustion sources as set-forth in 40 CFR § 98.33(c).(l) Hydrogen producers shall use the methodology found in section 95113(d) to calculate and report CO2, CH4, and N2O emissions from all flaring at their facility.Cal.
