KUCHING, Aug 30: Sarawak is set to export its first batch of green hydrogen (H₂) to Singapore, marking a significant milestone in the State’s clean energy drive and contribution to the global net-zero transition.
According to a media release, the Sarawak Economic Development Corporation Energy (SEDCE) is currently in talks with several potential offtakers for green H₂ export in solid form.
It is working with its technology partner, Hydrexia Holding Limited (Hydrexia), a leading provider of integrated hydrogen technology solutions, specialising in hydrogen production, storage, transport, and applications.
The metal hydride hydrogen storage technology (MHX) stores hydrogen molecules via magnesium hydride (MgH₂), which addresses transportation bottlenecks by offering intrinsic safety and higher storage density, suitable for road, rail, and sea applications.
“This reusable MHX storage container can safely be transported at ambient pressure and temperature, making it compatible with the highest purity requirements.
“The readiness of our unique MHX has reached the level of wide commercialisation. We are committed to serving the needs of hydrogen transport and storage in the SEA region,” said Alex Fang, the chairman and chief executive officer (CEO) of Hydrexia.
The media release also stated that SEDCE is currently producing green hydrogen molecules through a water electrolysis process using a proton exchange membrane (PEM) electrolyser, which utilises water and electricity supplied from the grid.
The Darul Hana H₂ plant is designed to produce 150kg of green H₂ daily, with the PEM method chosen as the current technology, as it fits the present demand in Sarawak.
There are currently ten fuel cell electric vehicles (FCEVs) or hydrogen vehicles in Sarawak, namely, five Toyota Mirai fleets used by the Premier of Sarawak, three Deputy Premiers, and the chairman of SEDC; three hydrogen buses operated by Sarawak Metro; and two Hyundai Nexo vehicles managed by Sarawak Energy.
“Having an operationally ready green hydrogen plant but not utilising its potential is uneconomical. With the limited demand we have now, we decided to turn this issue into an opportunity to maximise the plant’s capability,” said SEDCE CEO Robert Hardin.
Hydrogen molecules from the Darul Hana H₂ Plant are transported via tube trailers, which then undergo a hydrogenation process where the molecules are absorbed into the MHX unit.
The unit will later be exported to the offtake destination where the solid molecules are dehydrogenated for further use.
The first MHX unit bound for Singapore marks the first time green H₂ molecules produced in Sarawak have been exported, laying the foundation for a regional ecosystem and supporting the global energy transition. — DayakDaily
