The blending unit will be required to blend up to a maximum of 20% hydrogen by volume into the customers' existing natural gas supply. The injection will take place downstream of the meter where the end use is combustion to provide heat to the customers existing process. The customer process in non-interruptible and should the blend ratio go above the maximum allowable or if there is any failure of the hydrogen supply the blending infrastructure must be able to revert to 100% natural gas in order to maintain supply to the customer.
The blending infrastructure will need to be able to meet the requirements set out in the below Requirements section. These requirements are taken from the recently published FUNCTIONAL SPECIFICATION FOR HYDROGEN BLENDING INFRASTRUCTURE. WWU will own and operate the hydrogen blending unit and any associated equipment which will be located at the customers site in line with Model 2 in the functional blending spec.
FUNCTIONAL REQUIREMENTS
HYDROGEN PRESSURE REGULATION AND METERING Hydrogen pressure regulation and control is required to ensure there is sufficient pressure at the point of injection into the customers system. Pressure regulation and control shall be to IGEM/TD/13 and or IGEM/TD/23. Hydrogen volume and energy flowrate are required and the metering system shall be appropriate for hydrogen that is compliant with Table 5 of IGEM/H/1 and Table 2 of PAS 4444.
ACCURACY The hydrogen metering system should meet the accuracy requirements of Table 2 of the Functional Blending Specification in Appendix 1.
HYDROGEN/GCV CONTROL Hydrogen injection rate shall be controlled so as to achieve:
a minimum gross calorific value of gas at the comingled point
a hydrogen content of the blend that is no greater than a maximum of 20% by volume
a Wobbe index of the blend that is no less than the lower Wobbe limit permitted by Schedule 3 of the GSMR.GAS SAMPLING AND ANALYSIS
HYDROGEN SUPPLY Gas sampling and analysis shall continuously or continually monitor the hydrogen supplied to the hydrogen blending unit .
COMINGLED POINT Gas sampling and analysis shall continuously or continually monitor the blend at the comingled point and provide confirmation that it is compliant the minimum requirements agreed with WWU. A schedule of parameters that shall be monitored is given in Table 1 of the Functional Blending Specification.
Calorific value shall be determined using an instrument approved by Ofgem for determination of calorific values for the purposes of determining the reference point against which flow weighted average calorific value (FWACV) capping shall apply. The instrument shall comply with the requirements listed in an appropriate Letter of Approval from Ofgem.
ACCURACY The gas analysis system(s) shall meet the accuracy requirements of Table 3 of the Functional Blending Specification in Appendix 1.
REMOTELY OPERATED VALVE A Remotely Operated Valve (ROV) shall be supplied, which shall be capable of manual remote or automatic closure in the event of variation in blend outside of the agreed conditions or inability to provide sufficient blending where this is practiced. A more detailed description of trip and reset philosophy is given in the Gas Quality and Supervisory system functional block. The means of actuation of the ROV shall be the choice of WWU.
FWACV FUNCTIONALITY The system shall deliver the functionality required for the FWACV regime, namely requirements set out in the Gas (COTE) Regulations. Conditions currently specified include the following:
Acquisition and storage of gross CV of the supplied hydrogen from the approved CV determination device, together with a flag indicating its quality/suitability for use. For non-continual CV determination devices, the System - CV determination device interface shall be such that only one value of each CV determination is acquired.
Acquisition and storage of instantaneous volumetric flowrate of hydrogen at the time of acquisition of gross CV.
Initiation of daily calibration of CV determination device.
Automated tests of apparatus and equipment at periods not exceeding 35 days in accordance with Regulation 6(e) of the Gas (COTE) Regulations. The facility to manually initiate tests of apparatus and equipment either by, or at the request of, the Gas Examiner. Provision of a report of results of automated or manual tests in accordance with Regulation 6(e) of the Gas (COTE) Regulations.
Calculation of the daily average CV of the hydrogen at the end of each Gas Day in the manner specified by the Letter of Direction or by WWU depending on site specific conditions. This will require confirmation of the quality of individual records (records are Good if the CV determination device is operating within agreed limits) and averaging of only those records that are Good and for which gas is flowing past the sample point. In addition, a flag shall be stored indicating whether the resulting daily average CV is Valid (i.e., the maximum time between Good records is less than 8 hours). Gross CV values during calibration or tests of apparatus and equipment shall not be included for averaging.
Acquisition and storage of integrated daily volume at the end of the Gas Day.
In addition to local storage of individual data acquired, appropriate means of secure transfer of data to WWU
Any software and hardware solutions are acceptable provided they deliver the required FWACV functionality, but WWU will require demonstration that the required functionality has been delivered.
GAS QUALITY AND SUPERVISORY SYSTEM The Gas Quality and Supervisory system shall monitor hydrogen and blend quality signals from the hydrogen blending unit instrumentation, the remote monitoring unit instrumentation and the delivery facility instrumentation. Monitoring shall be continuous or continual and provide confirmation that the blend at the comingled point is compliant with the requirements set out by Table 1 of the functional blending specification.
In the event of an excursion in any of the parameters or any other parameters agreed by risk assessment (see 6.2 in the full blending specification document) the trip system shall initiate closure of the ROV on the hydrogen feed and prevent further injection of hydrogen into the customer process. The system should revert to a pure natural gas feed to ensure that customer operations are not interrupted.
The limit values in the parameters of Table 1 are indicative and site-specific values shall be agreed during design approval and may be subject to review if risk assessment confirms such a requirement (see 6.2 in the full blending specification document). All alarms and trips shall therefore be configurable.
If closure of the ROV has been initiated because of non-compliance with the parameters in Table 1 or any other parameters agreed by risk assessment (see 6.2 in the full blending specification document ), then its subsequent opening shall be under the sole control of WWU.
DESIGN APPROVAL ASSETS OWNED BY WWU
Design approval for all assets owned by WWU shall be managed in accordance with IGEM/GL/5 and T/PM/GL/5.
TESTING ASSETS OWNED BY WWU
Pressure testing of all pressure containing components and systems shall be carried out in accordance with Management/Work Procedure PT/1 pertaining to WWU. Testing of electrical and instrument systems and equipment shall be carried out in accordance with BS 7671 and BS EN 60079-14.
COMMISSIONING AND INITIAL VALIDATION
