Clean Hydrogen Production Based on Chemical Looping Technology: Micro- to System-Levels Developments
view moreCredit: Muhammad Aziz
A transformative approach to clean hydrogen production is set to take center stage in an upcoming international webinar that bridges molecular innovation with industrial-scale decarbonization.
On Wednesday, November 26, 2025, at 18:00 Beijing Time (CST), Dr. Muhammad Aziz, Associate Professor and Lab Head at the Institute of Industrial Science, The University of Tokyo, will present his cutting-edge research on chemical looping-based hydrogen production, a technology that simultaneously generates high-purity hydrogen, captures CO₂, and recovers usable heat or power.
Unlike conventional steam methane reforming, which emits large amounts of carbon dioxide, chemical looping uses a closed-loop system of three interconnected reactors (fuel, steam, and air) and specialized oxygen carriers to enable efficient, low-emission hydrogen generation. Dr. Aziz’s work spans from microscopic analysis of oxygen carrier durability and reaction mechanisms to system-level integration across energy and heavy industries, offering a scalable blueprint for a hydrogen-powered future.
This talk will explore:
- How advanced oxygen carrier materials ensure stable, long-term reactor performance
- The role of process intensification in achieving near-zero-emission hydrogen
- Real-world applications in power generation, steelmaking, refineries, and renewable energy storage
- The remaining scientific, economic, and policy barriers to widespread adoption
Dr. Aziz is a globally recognized leader in sustainable energy systems, with over 300 peer-reviewed publications, a Google Scholar h-index of 62, and consistent recognition as a Top 2% Scientist worldwide by Stanford University (2021–2024). His Energy and Process Integration Lab at the University of Tokyo pioneers AI-driven optimization, digital twins, and circular energy solutions.
The session will be hosted by Prof. Siming You of the University of Glasgow, UK, a distinguished researcher in sustainable process engineering.
When: November 26, 2025, Beijing Time (CST): 6 pm
• Japan Standard Time (JST): 7 pm
• Greenwich Mean Time (GMT): 10 am
• Eastern Standard Time (EST, US & Canada): 5 am

SAN ANTONIO — November 17, 2025 — Southwest Research Institute (SwRI) has upgraded its hydrogen-powered heavy-duty internal combustion engine (H2-ICE) with a state-of-the-art turbocharger. The upgrades have significantly improved performance across the board, making the engine competitive with current long-haul diesel engines focused on fuel economy while maintaining near-zero tailpipe emissions.
In 2023, SwRI converted a traditional natural gas-fueled internal combustion engine to run solely on hydrogen fuel with minimal modifications. It was integrated into a Class-8 truck as part of the Institute’s H2-ICE project to demonstrate a cost-efficient hydrogen-fueled engine as an option for zero-tailpipe carbon dioxide heavy-duty transportation.
The new turbocharger unit increases the truck’s already solid performance by increasing peak torque from 1,494 to 1,760-foot pounds (lb-ft) and peak power from 370 to 440 horsepower (hp). Modern long-haul heavy-duty engines range from 1,450 to 1,850 lb-ft and range between 400-500 hp.
“Upgrading this driven turbocharger gave us the airflow needed to continue improving the engine’s performance,” said Chris Bitsis, assistant director of SwRI’s Powertrain Systems Engineering Department, who oversees combustion research programs. “For instance, in addition to the torque and horsepower gains, the engine’s peak efficiency has also improved to 44.0%, which is class-leading for a spark-ignited engine. The torque and power ratings are comparable with diesel trucks focused on fuel economy currently on the road with the bonus of near-zero tailpipe emissions.”
Hydrogen engines often struggle to maintain the airflow necessary during fast acceleration to eliminate preignition and minimize NOX emissions. SwRI addressed this challenge by working with a commercial supplier that engineered the new turbocharger to SwRI’s specifications. The turbocharger shaft is mechanically linked to the crankshaft through a variable drive, allowing it to provide the necessary boost pressure on-demand.
“This is a significant milestone in the history of SwRI’s hydrogen combustion engine program and provides further evidence of the technology’s readiness,” Bitsis said. “We are excited to continue pushing this technology forward for a sustainable future.”
The Class 8 demonstration vehicle was developed as part of SwRI’s Hydrogen Internal Combustion Engine (H2-ICE) consortium. SwRI continues helping the automotive and transportation industries understand and address technical challenges in developing clean and efficient hydrogen vehicles. The consortium’s completed Class 8 H2-ICE demonstration vehicle offers the long-haul trucking market another zero-greenhouse gas option. Learn more at H2-ICE2.
“I am proud of our team at SwRI for demonstrating that there is a high efficiency, zero-emission transportation solution available to help reduce CO2 and criteria pollutants,” said Daniel Stewart, Vice President of SwRI’s Powertrain Engineering Division. “The U.S. has the engine factories and supply chains necessary to put this technology into production today.”
