Hydrogen News: Towngas Advances Hydrogen Infrastructure for Hong Kong Construction Sites and Data Centres

The Hong Kong and China Gas Company Limited (Towngas) is making some exciting moves by transitioning from hydrogen pilot tests to rolling out hydrogen solutions at construction sites and data centers throughout Hong Kong. The aim here? Deliver reliable, low-emission energy where the grid isn't quite cutting it, especially when backup power is essential. By deploying compact, containerized hydrogen power units, Towngas is aligning itself with the city's decarbonization ambitions and showing just how effective clean hydrogen can be in tackling real-world challenges right now. This initiative builds on their recent projects, including Hong Kong’s very first hydrogen-powered EV charging station located at Towngas’s North Point headquarters.

A strategic shift from pilots to purpose

Towngas has been dabbling in hydrogen extraction from its town gas network since at least 2021, testing the waters in places like Tai Po and collaborating on trials in Sai Kung. Executives Sammy Kong Siu-kuen and Don Cheng Hill-kwong have shared their vision to evolve beyond just proof of concept to practical applications where operations deal with grid limitations or need robust backup. Currently, hydrogen makes up about half of their town gas mix, with a supply capacity standing at roughly 34 tonnes a day. Recent government approvals indicate the go-ahead for about eight trial projects involving Towngas in areas like North Point and the Hong Kong Science Park. Instead of spreading their efforts thin, the company is now laser-focused on addressing clear customer needs, presenting hydrogen as a viable alternative to diesel generators and costly electrical upgrades.

Solving real-world power challenges

You know how grid constraints can slow down big construction projects? They often leave operators with no choice but to rely on noisy, dirty diesel generators. And then there are data centers—those places run on barely a whisper, needing near-zero downtime and minimal emissions. Here’s the clever part: compressed hydrogen cylinders feed on-site power units that use fuel cells to generate electricity. In a fuel cell, hydrogen molecules split into protons and electrons, creating an electric current while the only byproduct is good old water. At Towngas’s North Point site, this bottled-hydrogen solution powers three EV chargers without any major infrastructure fuss. It's a real-world example of how hydrogen fuel cell technology is moving from theory to practice.

Made in Hong Kong, made for Hong Kong’s future

This new venture is all about leveraging local resources and talent at every stage. Towngas’s impressive 3,700-kilometer pipeline network already handles hydrogen-rich town gas, boasting an annual production capability of over 12,000 tonnes. And for green hydrogen? Their partnership with Veolia at the South East New Territories landfill extension is turning biogas into a renewable fuel source, transforming waste into energy. Engineering partner CIMC Enric is stepping in to provide modular equipment for safe storage and power generation. By designing, assembling, and certifying everything locally, this initiative encapsulates the ethos of being made in Hong Kong, made for Hong Kong’s future. Local production not only shortens lead times and cuts costs but also strengthens the city’s budding hydrogen infrastructure by training technicians and developing safety standards.

Positive environmental and economic impact

Switching from diesel to hydrogen isn’t just a smart move environmentally—it’s a game-changer. Local emissions of nitrogen oxides and particulate matter drop to nearly zero, and with noise levels taking a nosedive, both construction crews and nearby residents benefit from a more pleasant environment. Water vapor is the only emission that results, effectively eliminating soot and odors. On the economic front, this rollout opens up job opportunities across the entire hydrogen supply chain, from logistics to maintenance, safety checks, and equipment manufacturing. Plus, by capturing landfill methane for hydrogen production, this project helps keep greenhouse gases from escaping into the atmosphere, further supporting green hydrogen production throughout the region.

Expanding skills and community engagement

But it’s not just about the tech; this hydrogen rollout is all about building local expertise too. Towngas has organized training workshops for site safety officers and technicians, working alongside industry groups and the Environment and Ecology Bureau. They've even held community briefings around pilot project sites to outline safety protocols, environmental benefits, and emergency response measures. These outreach efforts are essential for fostering public trust in hydrogen technology—a must for future expansions into areas like transportation or urban microgrids. By investing in knowledge transfer from the get-go, Towngas is setting the groundwork for a skilled workforce that can keep the clean hydrogen momentum going citywide.

Looking ahead with policy and partnerships

By pinpointing areas where grid updates are too slow or costly and where diesel generators are still the go-to, Towngas is carving a solid pathway for clean hydrogen in Hong Kong’s bustling urban landscape. This pragmatic, niche-first approach is in tune with global trends for stationary hydrogen applications, demonstrating that infrastructure can evolve gradually instead of all at once. If these early deployments prove their worth, they could lead to more extensive installations in logistics hubs, offshore sites, and even urban microgrids. For now, Towngas’s leap from pilot projects to purposeful implementation shows that hydrogen infrastructure can provide greener, quieter, and more resilient power solutions just where they're needed the most.
