Unlocking Hydrogen’s Future: Fudan University’s Low-Cost Catalytic Breakthrough

Hydrogen has long been hailed as the clean fuel of the future, but challenges with purification, storage, and transport have slowed its rise. Producing high-purity hydrogen is expensive, and moving it safely from where it’s made to where it’s needed often requires specialized, costly infrastructure.

A team of researchers at Fudan University may have found a way to overcome those roadblocks. They’ve developed a low-cost catalytic cycle that can separate hydrogen from impure industrial gas streams, store it safely in liquid form, and transport it using existing fuel infrastructure. The process uses two common organic compounds—γ-butyrolactone (GBL) and 1,4-butanediol (BDO)—along with an inexpensive copper-based catalyst.

The process begins by capturing hydrogen from gas feeds that can contain more than 50% impurities, such as carbon monoxide, carbon dioxide, and hydrocarbons. At around 170°C, the catalyst converts GBL into BDO while locking in the hydrogen. This BDO is an oil-like liquid that can be handled using the same tanks, trucks, and pipelines already used for fuels, making the system simple to deploy.

When the hydrogen is needed, the reaction is reversed. BDO is converted back to GBL, releasing ultra-pure hydrogen with a purity of more than 99.998%. The catalyst’s ability to tolerate high levels of impurities without deactivation is a major advantage, allowing it to process gas streams that would render many conventional catalysts useless.

The implications are significant. Industrial byproduct hydrogen, which is often vented or burned as waste, could be upgraded into a valuable, clean energy source. The ability to store and transport hydrogen easily opens the door for its wider use in power generation, heavy-duty transport, and backup energy systems. Because the process works with current fuel handling infrastructure, it avoids the need for massive new investments in pipelines or storage facilities.

This approach could accelerate the adoption of hydrogen as a mainstream energy carrier, cutting costs and improving safety while making the fuel far more practical. Researchers are now working with industry partners to scale up the system, explore other liquid carrier options, and expand its use to scenarios ranging from industrial waste recovery to renewable energy storage.
