Towngas and CIMC Enric have launched a hydrogen-powered EV charging system in Hong Kong to bypass power grid limitations in older commercial buildings. The system uses bottled hydrogen to generate electricity for EV chargers, removing the need for expensive electrical infrastructure upgrades. The project aims to utilize green hydrogen produced from landfill gas at Tseung Kwan O. This approach provides a flexible, off-grid power solution for high-density urban environments where upgrading the existing power load is physically or financially impractical.

Using hydrogen as a buffer for EV charging in old buildings is a clever way to avoid the nightmare of upgrading aging switchgear. I am curious about the actual cost per kWh compared to the grid. Bottled hydrogen logistics usually add a heavy premium.

Exactly. The hardware is one thing, but the maintenance of those fuel cells and the delivery schedule for the bottles will be the real test. If it is easier than ripping out walls for new cables, building managers might actually bite.

The mention of landfill gas to green hydrogen is the key part here. Without a certified low-carbon source, this is just shifting the emissions. I want to see the certification framework they mentioned for 2027 to see how they track the carbon intensity.

Towngas is trying to find a use case for hydrogen that does not require a total overhaul of the city's pipes. Bottled supply is a decent bridge, but the scale is tiny. Three chargers is a pilot, not a systemic shift.
