📢 Turbochargers for H₂ ICE: Thermal and Aerodynamic Adaptation in Hydrogen Combustion Engines
🚛 Introduction: Cummins Launches Specific Turbo for H₂ Engines. Cummins has developed a new turbocharger designed for hydrogen internal combustion engines (H₂ ICE), aimed at heavy-duty vehicles. Unlike diesel engines, H₂ engines require significantly higher airflow and present specific thermal and material challenges due to the presence of water vapor in the exhaust gases.
1️⃣ Technical Features of the H₂ ICE Turbocharger
The system incorporates variable vanes that adjust exhaust flow according to engine speed.
At low rpm, the vanes close to increase boost pressure; at high rpm, they open to maintain performance.
The design must withstand water vapor-induced corrosion and the thermal properties of hydrogen.
2️⃣ Operational Differences Compared to Diesel Engines
Hydrogen has a lower energy density than diesel, requiring a larger volume of air for efficient combustion.
Boost pressure must be higher and more stable to compensate for the fuel’s lower density.
Turbocharger materials must resist oxidation and thermal fatigue over long cycles.
3️⃣ Industrial Implications and Technology Adoption
The development of turbochargers specific to H₂ ICE opens up new possibilities for the decarbonization of heavy-duty transport without direct electrification.
Truck and heavy machinery manufacturers are evaluating their integration as a transition solution in markets with limited green H₂ infrastructure.
Compatibility with existing engines could accelerate adoption in industrial fleets.
🛠️ This advancement is useful for automotive engineers, thermal system designers, and combustion specialists working on adapting conventional technologies to use H₂. The design of dedicated turbochargers allows for maintaining efficiency and reliability in engines running on alternative fuels.
📘 Professional Conclusion: Is H₂ ICE a viable bridge solution?

📢 Biohydrogen in Puertollano: Energy Transition or Rethinking Gray Hydrogen?
🏭 Introduction: Repsol Rethinks Its H₂ Strategy in Ciudad Real After canceling its GREEN HYDROGEN project in Puertollano due to “technical and economic infeasibility,” Repsol announces a new investment of €16 million to produce BIOHYDROGEN from organic waste. The initiative seeks to reduce the carbon footprint of its synthetic fuels, although experts warn that it is a weakened form of GREY HYDROGEN, with little climate impact.
1️⃣ From Electrolyzers to Biogas: A Technological Paradigm Shift
The original project contemplated a 30 MW ELECTROLYZER financed with €10 million in public funds.
The new proposal replaces fossil gas with biogas to generate H₂ through thermal reforming.
The CO₂ needed to synthesize fuels will be captured from the refinery’s chimneys, maintaining dependence on oil.
2️⃣ Climate Impact and Energy Efficiency
Biohydrogen can reduce up to 29,000 tons of CO₂ per year, according to internal estimates.
However, the process efficiency is less than 10%, compared to 95% for electric motors.
The end use of H₂ in synthetic fuels involves direct CO₂ emissions in vehicles.
3️⃣ Structural Limitations and Raw Material Dependence
The availability of organic waste is limited, and its demand is growing in sectors such as chemicals and food.
Spain has only 260 biogas plants, compared to more than 20,000 in Europe.
Traceability and certification of waste is critical to prevent fraud and associated deforestation.
🛠️ This case is relevant for energy managers, industrial sustainability managers, and regulatory analysts assessing the viability of H₂ technologies in refining. The project’s reformulation highlights the need for clear technical criteria to distinguish between transition solutions and reputational containment strategies.
📘 Professional conclusion: How to audit the real energy transition? Should a technical taxonomy be established to differentiate renewable H₂ from biogas reforming? What verification mechanisms should be applied to publicly funded projects to avoid greenwashing?

📢 Optimization of Electrolysis with Platinum-Doped NiFe-MOF Catalysts: Performance and Scalability
🔎 Introduction: Improving H₂ Generation through Structural and Electronic Design. Electrochemical hydrogen production faces technical and economic challenges, particularly due to its dependence on scarce noble metals. This study presents a new class of platinum-doped nickel-iron-based metal-organic framework (MOF) catalysts designed for high-efficiency water electrolysis with lower precious metal content.
1️⃣ Controlled Architecture for Increased Catalytic Activity
The NiFe-MOF catalysts were synthesized using solvothermal methods and post-synthetically modified to introduce Pt loadings (0.5–2.0 wt%).
The porous structures were optimized using mixed ratios of the H₄DOBDC ligand (1:0 to 1:1), achieving diameters close to 4.2 nm and surface areas of 1325 m²/g.
Electrochemical tests in 1.0 M KOH showed improved kinetics; the Pt-NiFe-MOF-1.0 catalyst required only 253 mV for OER and 58 mV for HER at 10 mA/cm².
2️⃣ Mechanistic Analysis with DFT and XPS Spectroscopy
DFT calculations revealed that Pt doping generates synergistic effects by modifying hydrogen adsorption energies.
XPS analysis confirmed that Pt does not act as a direct catalyst in OER, but rather electronically polarizes neighboring Ni and Fe centers.
This favors the formation of high-valent Ni³⁺/Fe³⁺ species, lowering the energy barrier to OO bond formation.
3️⃣ System Integration and Operational Stability
A custom-built integrated system operating at 75°C achieved 1.62 V at 100 mA/cm² with a power efficiency of 75.8%.
Continuous operation for 200 h demonstrated stability, with precious metal loadings 15–30 times lower than conventional systems.
The design balances performance and material cost, boosting the industrial viability of H₂ systems.
🛠️ Direct Applicability in Industrial Environments This catalytic system represents a practical alternative for engineers specializing in PEM or alkaline electrolysis platforms, and for researchers in scalable MOF materials. By reducing dependence on noble metals and improving energy efficiency, it addresses key challenges for the industrial deployment of H₂.
📘 Professional reflection: Efficiency with less platinum? Can electronically tuned MOF architectures redefine the cost-performance trade-off in large-scale electrolysis? What is the acceptable threshold for noble metals for industrial systems with limited budgets?

📊 Introduction: Energy projections enhanced by the new Hydrogen Market Module The U.S. Energy Information Administration (EIA) has released its Annual Energy Outlook 2025 (AEO2025), featuring the debut of the Hydrogen Market Module (HMM). This model enables simulations of the hydrogen market under regulatory and technological scenarios. In most cases analyzed, H₂ production is projected to increase by 80% by 2050 compared to 2024, with steam methane reforming (SMR) remaining the primary production pathway.
🔎 1. Supply Composition and Technological Trends
In the reference scenario, H₂ production could reach 14.3 million metric tons (MMmt) by 2050.
Over 80% of output would derive from unabated SMR, while SMR + CCS would peak in the 2030s at 2 MMmt, declining after federal incentives expire in 2045.
Electrolysis would contribute less than 1% of supply, even when factoring in the 45V tax credit.
⚙️ 2. Economic and Regulatory Drivers
The modeling approach considers only laws effective as of December 2024, excluding recent changes such as the One Big Beautiful Bill.
In low gas supply scenarios, SMR becomes less cost-competitive.
In high-growth macroeconomic conditions, H₂ market size could reach 15.5 MMmt, driven by bulk chemical demand.
🚚 3. Sectoral Applications and Expansion Limits
The heavy-duty transport sector emerges as the main driver in policy-supported scenarios.
Without regulatory standards, H₂ consumption for mobility remains minimal.
Industrial by-product H₂—such as from propane dehydrogenation—accounts for the second-largest production pathway.
🛠️ This analysis benefits energy modelers, strategic planners and hydrogen project developers assessing the feasibility of SMR, CCS and electrolysis technologies based on fiscal incentives, feedstock costs and sectoral demand. The HMM enables high-resolution simulations in both regulatory and technological dimensions.
