On-Site Hydrogen Gains Ground as Teledyne and JTEKT Push Industrial Decarbonisation Forward

A quiet but important shift is underway in industrial decarbonisation: instead of waiting for large-scale hydrogen infrastructure to materialise, companies are beginning to produce and use hydrogen directly at their own facilities. A new deployment by Teledyne Energy Systems and JTEKT Corporation offers a clear example of how this model is starting to move from concept to reality.

At JTEKT’s carbon-neutral plant in Aichi Prefecture, Japan, a hydrogen generation system from Teledyne is now replacing liquefied natural gas in aluminum melting processes—one of the more energy-intensive operations in manufacturing. The system, known as the Titan™ EL Series, uses alkaline water electrolysis to produce high-purity hydrogen on site, eliminating the need for external fuel supply and significantly reducing emissions from combustion.

What makes this development notable is not just the use of hydrogen, but how it is being deployed. Rather than relying on hydrogen transported over long distances—an approach that still faces infrastructure and cost challenges—this project generates hydrogen exactly where it is needed. The result is a self-contained energy loop: hydrogen is produced, stored, and consumed within the same facility.

This approach addresses one of the biggest bottlenecks in the hydrogen economy: distribution. While hydrogen is often promoted as a key pillar of future low-carbon energy systems, the infrastructure required to move it at scale—pipelines, storage terminals, shipping—remains underdeveloped in many regions. On-site generation sidesteps this issue, at least for certain industrial applications, and allows companies to begin reducing emissions immediately.

In JTEKT’s case, the shift is expected to cut around 56 metric tons of CO₂ emissions annually. While that figure may appear modest in absolute terms, it represents something more significant: a proof of concept for decarbonising high-temperature industrial processes, which are traditionally difficult to electrify.

Aluminum melting, like steelmaking or cement production, requires intense and consistent heat. Electrification can be technically challenging or economically unviable in such settings, which is why hydrogen—capable of delivering high-temperature combustion without direct carbon emissions—is gaining attention as a practical alternative.

The Teledyne system produces approximately 112,000 normal cubic meters of hydrogen per year, powered by a mix of renewable grid electricity and on-site solar generation. This combination is critical. Hydrogen is only as “green” as the energy used to produce it; when generated using renewable electricity, it becomes a near-zero-emission fuel. When produced from fossil fuels, its climate benefits are far more limited.

This project therefore reflects a broader trend: the convergence of renewable power, hydrogen production, and industrial use into integrated systems. Instead of treating these elements as separate components, companies are increasingly designing facilities where energy generation and consumption are tightly linked, improving efficiency and reducing emissions across the board.

There are also operational advantages. Producing hydrogen on site gives manufacturers greater control over supply, reduces exposure to fuel price volatility, and can improve system efficiency by eliminating transport losses. For industries operating in competitive global markets, these factors are as important as environmental considerations.

However, challenges remain. Electrolysis systems require significant upfront investment, and their economics depend heavily on the availability and cost of renewable electricity. In regions where clean power is limited or expensive, scaling this model may prove difficult. There are also technical considerations, such as adapting existing equipment to safely handle hydrogen combustion.

Despite these hurdles, the direction of travel is clear. Industrial companies are under increasing pressure—from regulators, investors, and customers—to reduce emissions not just in the long term, but now. Technologies that can be deployed quickly, without waiting for large-scale infrastructure, are therefore gaining traction.

The collaboration between Teledyne and JTEKT highlights how this transition is beginning to take shape in practice. It demonstrates that hydrogen is no longer confined to pilot projects or future scenarios; it is starting to play a tangible role in real industrial environments.

More broadly, it signals a shift in how decarbonisation is being approached. Rather than relying on a single breakthrough solution, industries are adopting a portfolio of technologies—renewables, hydrogen, efficiency improvements, and carbon capture—tailored to specific processes and constraints.

On-site hydrogen generation may not be the answer for every facility, but it offers a compelling pathway for sectors where alternatives are limited. As more companies experiment with and refine this model, it could become an important building block in the wider effort to create low-carbon industrial systems.

In that sense, the JTEKT project is less about a single plant in Japan and more about a growing realisation: the energy transition will not only be powered by new sources of energy, but also by new ways of delivering and using that energy—right where it is needed most.
