Hydrogen & e‑fuels KPIs by sector (with ranges)
Essential KPIs for Hydrogen & e‑fuels across sectors, with benchmark ranges from recent deployments and guidance on meaningful measurement versus vanity metrics.
Start here
Global clean hydrogen production capacity reached roughly 1.5 million tonnes per year by early 2026, yet less than 4% of announced projects have reached final investment decision. The gap between ambition and execution in hydrogen and e-fuels demands rigorous, sector-specific KPIs that separate viable deployments from press releases. This benchmark deck provides the metrics that matter, with ranges drawn from operational projects and credible feasibility studies across key end-use sectors.
The Hydrogen and e-Fuels Landscape in 2026
The Hydrogen Council estimates over $570 billion in announced hydrogen investments globally, but only $75 billion has reached FID. Europe leads on electrolyzer deployment, with 3 GW of installed capacity, while the US Inflation Reduction Act's Section 45V production tax credit (up to $3/kg for green hydrogen) has catalyzed a wave of project announcements across the Gulf Coast and Midwest.
E-fuels, synthetic hydrocarbons produced from green hydrogen and captured CO2, remain at earlier stages. Total global e-fuel production capacity sits below 50,000 tonnes per year, concentrated in pilot and demonstration plants. Yet regulatory mandates are building demand: the EU's ReFuelEU Aviation regulation requires 1.2% synthetic aviation fuel by 2030, and the FuelEU Maritime regulation introduces carbon intensity targets that favor green hydrogen and ammonia.
The challenge is translating policy signals into bankable projects. The KPIs below provide the benchmarks needed to evaluate projects, compare pathways, and avoid vanity metrics that obscure real performance.
The 8 KPIs That Matter
1. Levelized Cost of Hydrogen (LCOH) by Production Pathway
Definition: Fully-loaded cost of producing one kilogram of hydrogen, including capital expenditure, energy, operations, water, and financing.
| Pathway | Low Range ($/kg) | Median ($/kg) | High Range ($/kg) | 2030 Target |
|---|---|---|---|---|
| Grey (SMR, unabated) | $1.00 | $1.50 | $2.20 | N/A |
| Blue (SMR + CCS) | $1.80 | $2.50 | $3.50 | $1.50-2.00 |
| Green (Alkaline electrolyzer) | $3.50 | $5.00 | $7.50 | $2.00-2.50 |
| Green (PEM electrolyzer) | $4.00 | $5.80 | $8.50 | $2.00-2.50 |
| Green (SOEC, high-temp) | $4.50 | $6.50 | $9.00 | $1.80-2.50 |
| Pink (Nuclear-powered) | $3.00 | $4.50 | $6.00 | $2.50-3.50 |
Key insight: Green hydrogen costs remain 2-4x above grey hydrogen in most regions. Achieving parity requires electricity below $25/MWh, electrolyzer capex below $300/kW, and capacity factors above 50%. The 45V tax credit at $3/kg closes the gap for well-sited US projects, but only when meeting hourly matching and additionality requirements.
2. Electrolyzer Efficiency and Degradation
Definition: Electrical energy consumed per kilogram of hydrogen produced, and performance decline over operating life.
| Technology | Energy Input (kWh/kg H2) | System Efficiency (LHV) | Annual Degradation | Stack Lifetime |
|---|---|---|---|---|
| Alkaline | 50-58 | 57-67% | 0.5-1.0% | 60,000-90,000 hrs |
| PEM | 52-62 | 54-64% | 1.0-2.0% | 40,000-80,000 hrs |
| SOEC | 37-42 | 80-90% | 1.5-3.0% | 20,000-40,000 hrs |
| AEM | 52-65 | 51-64% | 2.0-4.0% | 15,000-30,000 hrs |
Why it matters: Electrolyzer efficiency drives the largest variable cost component: electricity. A 10% improvement in efficiency at $40/MWh electricity saves roughly $0.40/kg H2. However, SOEC's superior electrical efficiency must be weighed against higher degradation rates and the cost of supplying high-temperature heat. Evaluate projects on demonstrated system efficiency under variable renewable input, not nameplate ratings under steady-state conditions.
3. Capacity Factor and Utilization Rate
Definition: Actual hydrogen output as a percentage of maximum theoretical output over a given period.
| Application | Typical Range | Leading Projects | Minimum Viable |
|---|---|---|---|
| Grid-connected (firm power) | 85-95% | >95% | 80% |
| Dedicated renewables (co-located) | 30-55% | 55-65% | 25% |
| Hybrid (renewables + grid backup) | 55-80% | >80% | 45% |
| Behind-the-meter industrial | 70-90% | >90% | 60% |
Critical trade-off: Higher capacity factors reduce capital cost per kilogram but may compromise emissions credentials. Running electrolyzers on grid power during low-renewable periods increases carbon intensity. The EU Delegated Act and proposed US 45V guidance require temporal matching (hourly by 2028 in EU) to qualify as "green," creating a fundamental tension between economics and certification.
4. Carbon Intensity (kg CO2e/kg H2)
Definition: Lifecycle greenhouse gas emissions per kilogram of hydrogen produced, including upstream energy, water treatment, and equipment manufacturing.
| Pathway | Carbon Intensity Range | Threshold for "Low-Carbon" |
|---|---|---|
| Grey (SMR) | 9.0-12.0 | Does not qualify |
| Blue (SMR + 90% CCS) | 1.5-4.5 | Qualifies if <4.0 |
| Blue (SMR + 56% CCS) | 4.0-7.0 | Marginal |
| Green (dedicated renewables) | 0.3-1.5 | Qualifies |
| Green (grid mix, EU avg) | 2.5-8.0 | Depends on grid factor |
| Pink (nuclear) | 0.4-1.8 | Qualifies |
Vanity metric warning: Many blue hydrogen projects report capture rates of 90-95% on the reformer unit but exclude upstream methane leakage. When fugitive methane emissions of 1-3% are included, lifecycle carbon intensity can double. Evaluate blue hydrogen on well-to-gate lifecycle analysis, not point-source capture rates.
5. E-Fuel Production Cost ($/liter diesel equivalent)
Definition: Fully-loaded cost of producing one liter of synthetic fuel (e-diesel, e-kerosene, e-methanol) in diesel-equivalent energy terms.
| E-Fuel Type | Current Cost ($/L de) | 2030 Projected ($/L de) | Fossil Equivalent |
|---|---|---|---|
| E-methanol | $2.50-4.50 | $1.20-2.00 | $0.40-0.60 |
| E-kerosene (SAF) | $3.50-6.00 | $1.50-2.80 | $0.50-0.70 |
| E-diesel (Fischer-Tropsch) | $4.00-7.00 | $1.80-3.20 | $0.50-0.70 |
| E-ammonia (green) | $0.80-1.40/kg | $0.40-0.70/kg | $0.30-0.45/kg |
Key insight: E-fuels remain 5-10x more expensive than fossil equivalents. Cost reduction depends on three simultaneous improvements: cheaper green hydrogen (<$2/kg), cheaper captured CO2 (<$100/tonne for DAC, <$50 for point-source), and higher Fischer-Tropsch or methanol synthesis plant utilization. Mandates and carbon pricing, not cost parity, will drive near-term adoption.
6. Water Consumption (liters/kg H2)
Definition: Total freshwater consumed per kilogram of hydrogen, including process water and cooling.
| Process | Water Consumption (L/kg H2) | Water Quality Required |
|---|---|---|
| Electrolysis (PEM) | 9-15 | Ultrapure (Type II) |
| Electrolysis (Alkaline) | 10-18 | Deionized |
| SMR (Grey/Blue) | 13-22 | Treated industrial |
| Seawater electrolysis (emerging) | 0 freshwater | Seawater + desalination |
| Cooling systems (evaporative) | 20-50 (additional) | Raw/recycled |
Often overlooked: Water stress is a growing constraint in prime renewable energy regions (North Africa, Middle East, Australia). Projects in water-scarce areas need desalination infrastructure, adding $0.15-0.40/kg H2 to costs. Seawater electrolysis technologies under development by companies like Hysata and Verdagy aim to bypass this constraint but remain pre-commercial.
7. Infrastructure Readiness and Transport Cost
Definition: Cost of moving hydrogen from production to end use, including compression, liquefaction, pipeline, or carrier conversion.
| Transport Mode | Cost Range ($/kg H2 delivered) | Distance Sweet Spot | Maturity |
|---|---|---|---|
| Dedicated pipeline (new) | $0.50-1.50 | <500 km | Commercial |
| Repurposed natural gas pipeline | $0.15-0.50 | <1,000 km | Demonstration |
| Compressed gas truck | $1.00-3.00 | <300 km | Commercial |
| Liquid hydrogen truck | $2.00-5.00 | 300-1,500 km | Commercial |
| Ammonia carrier (ship) | $1.50-3.50 | >3,000 km | Commercial |
| LOHC (liquid organic carrier) | $2.50-5.00 | 1,000-5,000 km | Pilot |
Bottleneck alert: Transport and storage frequently add 30-60% to the delivered cost of hydrogen. Projects announcing low production costs without addressing delivery economics present incomplete pictures. The European Hydrogen Backbone initiative targets 28,000 km of pipeline by 2030 (60% repurposed), which would reduce delivered costs substantially for connected industrial clusters.
8. Offtake Security and Contract Structure
Definition: Firmness and duration of hydrogen purchase commitments from end users.
| Offtake Level | Characteristics | Project Bankability |
|---|---|---|
| Binding long-term (10-15 yr) | Fixed volume, indexed pricing, take-or-pay | High: enables project finance |
| Medium-term (5-7 yr) | Volume flexibility, price reopener clauses | Moderate: requires equity support |
| MOU/LOI | Non-binding, expression of interest | Low: insufficient for FID |
| Spot/merchant | No contract, market price exposure | Very low: speculative only |
Reality check: The IEA reports that fewer than 10% of announced green hydrogen projects have binding offtake agreements. Without secured demand, projects cannot achieve FID. Evaluate project viability by the strength of offtake, not the size of the electrolyzer order.
What's Working in 2025-2026
Industrial Cluster Models with Anchor Demand
The most bankable hydrogen projects are built around large industrial consumers that already use grey hydrogen. NEOM Green Hydrogen (Saudi Arabia) secured a 30-year offtake with Air Products for 600 tonnes/day of green ammonia. In the US, the DOE-funded Regional Clean Hydrogen Hubs (H2Hubs) structure projects around existing refinery and ammonia plant demand, reducing market risk.
The Port of Rotterdam's hydrogen import terminal combines multiple demand sources (refineries, chemicals, steel) with shared pipeline infrastructure, achieving delivered cost estimates 15-25% below standalone projects.
Green Ammonia for Maritime and Fertilizer
Green ammonia projects are advancing faster than other e-fuel pathways because ammonia has established logistics, storage infrastructure, and anchor demand in fertilizer production. Yara and ENGIE's partnership in Australia targets 800,000 tonnes per year of green ammonia. First Gen's project in the Philippines secured both fertilizer offtake and maritime fuel customers.
Green ammonia at $600-900/tonne is approaching competitiveness with grey ammonia at $400-500/tonne when carbon pricing of $80-120/tonne CO2 applies.
Electrolyzer Cost Curves Declining
Stack costs have fallen from $1,200-1,800/kW in 2020 to $500-800/kW in 2025 for alkaline systems. Chinese manufacturers (LONGi Hydrogen, Peric, Sungrow) are pushing prices toward $250-400/kW at GW-scale, though questions remain about performance validation and bankability for Western project finance. ITM Power, Nel Hydrogen, and Plug Power are scaling gigafactory manufacturing to compete.
What Isn't Working
Projects Without Secured Offtake
The hydrogen sector's biggest failure pattern is announcing multi-GW production projects before identifying who will buy the hydrogen. Analysis by Wood Mackenzie found that 65% of announced green hydrogen projects lack binding offtake agreements. These "supply-push" projects routinely miss timelines and require repeated re-scoping.
E-Kerosene Scale-Up
Synthetic aviation fuel production remains stuck at pilot scale. The world's largest e-kerosene facility (Atmosfair/Norsk e-Fuel in Norway) produces only hundreds of tonnes per year. Meeting the EU's 1.2% e-SAF mandate by 2030 requires roughly 360,000 tonnes annually. Current combined global capacity is below 5,000 tonnes. Capital commitments and construction timelines suggest a significant compliance gap.
Hydrogen for Heating
The UK's Hydrogen Village trial (intended for Whitby, Redcar) was cancelled after community resistance and cost analysis showing hydrogen heating costs 3-7x more than heat pumps on a per-unit-of-warmth basis. The efficiency penalty of producing hydrogen from electricity, then burning it for heat, versus using electricity directly in a heat pump, makes this pathway economically uncompetitive for residential applications in nearly all scenarios.

FAQ
Q: When will green hydrogen reach cost parity with grey hydrogen? A: In regions with excellent renewables (solar below $20/MWh) and policy support ($3/kg 45V credit or equivalent carbon price of $80-100/tonne), parity is achievable by 2028-2030. In regions without policy support, parity likely requires electrolyzer costs below $200/kW and electricity below $15/MWh, which pushes timelines to 2032-2035. Grey hydrogen cost varies with natural gas prices, so parity is a moving target.
Q: Are e-fuels viable for road transport? A: No, for passenger vehicles. Battery electric vehicles are 3-5x more energy-efficient than hydrogen fuel cells and 5-8x more efficient than e-fuels in tank-to-wheel conversion. E-fuels are economically justified only in sectors where direct electrification is impractical: long-haul aviation, deep-sea shipping, and certain industrial heat applications.
Q: How should investors evaluate blue vs. green hydrogen projects? A: Blue hydrogen offers lower near-term costs but carries methane leakage risk, CCS performance uncertainty, and potential stranded asset exposure if carbon prices rise or green hydrogen costs decline faster than expected. Green hydrogen has higher current costs but a clearer cost reduction trajectory and no upstream fossil fuel dependency. Portfolio approaches that weight green hydrogen for long-term positioning while accepting blue for near-term industrial decarbonization reflect the risk profile most accurately.
Q: What is the realistic scale-up timeline for e-fuels? A: Current global e-fuel production is below 50,000 tonnes per year. Reaching 1 million tonnes per year (roughly 0.02% of global liquid fuel demand) by 2030 would require 10-15 GW of dedicated electrolyzer capacity, multiple large-scale CO2 capture facilities, and Fischer-Tropsch or methanol synthesis plants at scale. This is technically feasible but requires sustained investment of $30-50 billion. E-fuels at meaningful scale (5-10% of aviation fuel) are a post-2035 reality.
