Towngas and Veolia to launch HK’s first green hydrogen production project

Production is expected to start in 2025.

The Hong Kong and China Gas Company Limited (Towngas) and Veolia have signed a memorandum of understanding to develop the city’s first green hydrogen project at the South East New Territories Landfill Extension (SENTX) in Tseung Kwan O.

Towngas and Green Valley Landfill, Limited, a joint venture company of Veolia, signed the agreement which is in line with Hong Kong’s hydrogen energy development direction.

“By utilising biogas to produce green hydrogen and promoting various hydrogen energy applications, the project aims to convert waste into energy,” a joint statement read.

The project was approved by the Inter-departmental Working Group on Using Hydrogen as Fuel led by the Environment and Ecology Bureau in March this year. 

The project includes a new hydrogen production unit, hydrogen transmission facilities, and a hydrogen refuelling station. 

Towngas and Veolia will collect biogas from the SENTX Landfill and convert it into green hydrogen with steam methane reforming technology through these facilities. 

Its production is expected to commence in 2025, with an expected daily capacity of around 330 kilograms of hydrogen that can power seven to eight hydrogen buses for a full day.

Peter Wong Wai-yee, managing director of Towngas, hopes the project can serve as a pilot demonstration. 

Once successfully implemented, the project can be replicated in other landfills and application scenarios, making good use of biogas to produce green hydrogen as a sustainable fuel, he added.
