SP Group establishes Southeast Asia’s first building powered by green hydrogen

Southeast Asia’s first building powered by green hydrogen has been opened by SP Group in Singapore, the energy utility company said today.

Located at Woodleigh park, the self-sustaining building is 100% powered with renewable energy via an innovative hydrogen energy system and is disconnected from the national electricity grid.

In the hydrogen energy system, electricity from green sources, such as solar, is used to conduct electrolysis.

The hydrogen generated from this process is bonded with special metal alloy powders to form metal hydride, compacted and stored in tanks.

When electricity supply is required, the stored hydrogen from the metal hydride tanks is slowly released and converted to electricity via fuel cells.

As green energy sources are used for electrolysis, this entire process of converting hydrogen to electricity is 100% green, with zero carbon emission.

“Buildings contribute 40% of energy related carbon emissions worldwide and the hydrogen energy system provides a safe and compact way of storing green hydrogen which powers the region’s first zero emission building,” Brandon Chia, Head of Centre of Excellence at SP Group, said.

“We believe this can be a significant contributor toward Singapore’s climate change pledge to cut national emissions intensity by 36% below 2005 levels by 2030.”

The hydrogen energy system has been developed by SP in conjunction with Marubeni Corporation and Tohoku University and was commissioned at the end of September.

The building was taken off the national electricity grid and connected to the system from mid-October.
