H2 Energy Sdn Bhd – 2.88 kWp Solar Powered Hydrogen Generation System (Malaysia)

This case study describes a pilot project by HT Energy (S) Sdn Bhd (HTES) to install a 2.88 kWp solar-powered hydrogen generation system at the Long Loyang Clinic in Sarawak, Malaysia. The system is designed to replace irregular and costly diesel power, providing 24/7 electricity for essential medical services, including refrigeration for vaccines and medicines.

• The Long Loyang Clinic previously relied on diesel generators that provided irregular and costly electricity, often failing during rainy seasons when roads became inaccessible or when fuel ran out. The clinic's average energy demand is 25-30 kW per day, used for lighting, defibrillators, and refrigeration of medicines and vaccines.
• HT Energy (S) Sdn Bhd (HTES) implemented a modular 'H2 system' with a peak load of 2.88 kWp to provide 25-30 kW of electricity daily (15 kW during the day and 10 kW at night). The system uses solar PV panels and an electrolyser to produce hydrogen gas, which is stored in tanks with a capacity of 30 Nm3, yielding 38 kWh when converted back to electricity.
• The project is expected to benefit 2,172 people in the community indirectly and create approximately 10 direct jobs. Environmentally, the system is estimated to reduce CO2 emissions by 13 to 33 tonnes annually compared to a full diesel-power scenario.
• Implementation faced challenges including bureaucratic approvals, customs delays, and logistical difficulties due to the site's remoteness and wet weather. Commissioning was further delayed by Malaysian government movement restrictions imposed during the COVID-19 pandemic.
• HTES intends to scale this technology to other rural settings, including schools and settlements. There are 57 other rural clinics in Sarawak identified as subjects for future projects, with HTES estimating a commissioning time of no more than five months from inception for similar projects.
