(General for system): Standard boundary conditions that apply to all electrolytic system KPIs: input of AC power and tap water; output of hydrogen meeting ISO 14687-2 at a pressure of 30 bar and hydrogen purity 5. Correction factors may be applied if actual boundary conditions are different.
All KPIs are interdependent and should be met simultaneously.

Notes:
KPI-1: Time that a maintained compressor system, with its minor components/parts (no core) being replaced, is able to operate until End-of-Life (EoL) criterium is met. For mature technology (TRL≥6), the main EoL criterium is the optimisation of total cost of system (evaluated as TCO, total cost of ownership as CAPEX + n∙OPEX(n), with OPEX dependent by time [year(n)] due to performance degradation). In mathematical terms, assuming a linear time degradation, lifetime is expressed in years as the square root of the ratio between CAPEX and yearly degradation (expressed as the yearly increment of maintenance and consumption cost due to the degradation of performance with respect to Beginning-Of-Life – BoL -, i.e., additional substitution spare parts). For emerging technology (TRL ≤5), EoL criterium assumes compression system (core parts) achieved the 90% of BoL performance (as compressed flow rate or pressure ratio).
KPI-2: Energy consumption to compress a kilogram of H2 from 5 bar(a) to 100 bar (without considering cooling power). Inlet pressure 5 bar(a), outlet pressure 100 bar(a) sufficient for most pipeline streams. This KPI is specifically for Pipeline application, and large-scale compression system (>1000 kg/d). Energy consumption needs only for the compression process, not include the cooling power. For mature tech (TRL≥6), KPI is focused on the system level, while for innovative tech (TRL ≤5), it regards the core part of technology.
KPI-3: Energy consumption to compress a kilogram of H2 from 30 bar(a) to 900 bar(a). This KPI is specifically for HRS application, and mid-scale compression system (200-1000 kg/d). Energy consumption needs only for the compression process, does not include the cooling power. For mature tech (TRL≥6), KPI is focused on the system level, while for innovative tech (TRL ≤5), KPI regards the core part of technology.
KPI-4: Mean time between failure (or stoppage) of the system that render the system inoperable without maintenance. PI connected to the technology. Reliability should be estimated by sufficient failure events in proper long-term tests. For mature tech (TRL≥6), failure can be associated to rupture, wear, degradation of compressors parts which occurs without correct maintenance while for innovative tech (TRL ≤5), failure focus exclusively on the key element of technology (e.g., membrane, electrochemical cell, or active material)
KPI-5: Ratio of the maintenance costs, both fixed and variable (including overhaul cost, repair cost, replacement cost, maintenance cost) per unit of compressed hydrogen output. Energy cost is not considered. Values is estimated as the ratio of total O&M cost (typical as annual percentage of CAPEX) and the yearly amount of compressed hydrogen, considering compressor availability/operating time about 100% (8760 hrs.). Same boundaries conditions as for KP-2 and KPI-3 for pipeline and HRS.
KPI-6: Capital cost of manufacturing of the compressor device (capital cost of system) normalised to the daily nominal capacity of the system. Fluid is pure hydrogen compliance with ISO 14687:2019. Same boundaries conditions as for KP-2 and KPI-3 for pipeline and HRS.
KPI-7: Concerning purification system.
KPI-8: Energy consumption to separate hydrogen from mixture. This KPI regards separation process, where it is necessary to extract hydrogen from a mixture with low hydrogen content. (e.g. H2 from gas grid). Energy consumption must take in consideration pressure and temperature requirements of the process. Additional efforts (compression, thermoregulation) should be taken in account to normalise the energy cost with respect to reference case (feed stream pressure 30 bar, temperature 300K). For mature tech (TRL≥6), KPI is focused on the system level, while for innovative tech (TRL ≤5), it regards the core part of technology. The feed/inlet H2 molar fraction must be between 0.1 to 0.75. KPI should be evaluated with a minimum recovery rate of hydrogen about 80%. Output H2 molar fraction must be > 99%
KPI-9: Energy consumption to purify hydrogen. This KPI regards purification process, where it is necessary to extract hydrogen from a mixture with high hydrogen content. (e.g. syngas). KPI for high TRL technology should be considered on the overall system, while it should be focused on the key components for low TRL technology. Energy consumption must take into consideration the technology's requirements for pressure or temperature.

KPI-10: Ratio between output purified hydrogen flow and hydrogen content into the input feed flow. For high technology TRL this regards overall purification/separation system. For low technology TRL, KPI focuses on the key elements of technology as membrane/electrochemical cell/active material. Output feed must be in compliance with ISO 14687:2019. Molar fraction in feed gas H2 for separation application should be in range between 0.1-0.75 molar fraction in feed gas H2 for purification application should be in range between 0.75-0.9995.
KPI-11: Levelised cost of separation or purification process, expressed as the cost for the processed mass of H2 in kg. KPI focus exclusively for high TRL technology. Minimum hydrogen recovery factor is 80%. Output H2 molar fraction must be > 99% or in compliance with ISO 14687:2019 for purification application, where it needs

KPI-4: The time a system was expected to operate minus the downtime, divided by the time a unit was expected to operate, expressed as a percentage. For micro-CHP demonstration, a minimum of ten units should be considered. For mid-scale or large-scale single units should be reported. Linked to O&M Cost (KPI-2): if maintenance interval is increased, then the availability of in base load running units will be also increased (i.e. 1 week in two years for maintenance).

Notes:
KPI-1: Hydrogen percentage content in gas turbine fuel, by mass (volume).
Boundary Conditions: applicable only to DLE technology. WLE technologies are not in scope. While state-of-the-art gas turbines can already handle 20% hydrogen by vol (blended in natural gas), development of gas turbines (and more specifically combustors) able to handle 0-100% H2 is a challenging and necessary task. Gas turbines operating in the range 0-100% H2 are required by users in the power generation market to ensure security of power supply in case of H2 shortages or lack of availability. Development of such combustors can be reached by gradually increasing the amount of H2 in gas turbines in the years to come to reduce technical risks.
KPI-2: NOx (NO + NO2) content in exhausts.
Boundary conditions: A fuel switch to hydrogen aims to retain all present strengths and ensure carbon-free energy conversion. Although the technological development of GT combustors aims to minimise NOx emissions, an increase in NOx formation is expected as the hydrogen content in the fuel is increased. This is a consequence of the higher reactivity of hydrogen and the related impact on flame stability, flame temperature etc. Conserving the same low-NOx emissions level of 25 ppmv@15%O2/dry when advancing from 30% (by volume) to 100% H2 remains a challenge. The conventional NOx normalisation method (15%O2/dry) is not designed to be translated across different fuels with different reactivity and exhaust gases. A more appropriate normalisation for NOx emissions is expressed in mg/MJ of fired-power, and therefore the KPI table also provides this alternative normalisation.
KPI-3: Hydrogen content during gas turbine start-up.
Boundary conditions: during start-up gas turbines are commonly fuelled with natural gas or liquid oil.
KPI-4: Reduction in electric efficiency of power plant when hydrogen-firing of the gas turbine is introduced (overall efficiency of power plant may be unaffected or increased through CHP schemes)
Boundary conditions: Evaluated at Full Speed Full Load condition. It refers to combined cycle gas turbines with bottoming steam cycle (CCGT). For the SoA, the actual maximum efficiency reduction is class-specific and largely depends on the class of the gas turbine.KPI-3: H2 content during gas turbine start up (during start up gas turbines are commonly fuelled with natural gas or liquid oil)
(KPI-4) and (KPI-2) are interdependent, increasing efficiency may increase NOx emissions, thus these two parameters require optimisation.
KPI-5: Percentage variation per minute of the gas turbine load with respect to the full load
KPI-6: Gas turbine ability to operate stably when facing unexpected H2 content in fuel. Evaluated with respect to nominal H2 content in fuel composition (blend of natural gas and H2)

KPI-1: Critical projects with pro-active safety management, including a periodically reviewed safety plan, educational measures, monitoring, etc. in percentage. Critical projects will be identified by the European Hydrogen Safety Panel, which will also assess the project safety management.
KPI-2: Projects reporting on safety (no events, near misses, incidents, accidents). Definitions of near-miss, incident, and accident according to EIGA document (INCIDENT/ACCIDENT INVESTIGATION AND ANALYSIS SAC Doc 90/13/E). Off-normal conditions to be reported in HIAD2.0 and/or HELLEN databases.
KPI-3: Number of safety workshops (e.g. on research priorities, risk assessment, end-use safety, etc.) and/or PNR/RCS workshops (e.g. permitting procedures for end-use installations, gaps analyses in specific aspects of the supply chain, etc.) at the programme level.
KPI-4: Number of Standards, Technical Specifications or Technical Reports at the scope of a PNR project. The impact will be measured after the end of the project, because of the different timelines of a PNR project and the SDO activities
