Methane-filled wastewater called Palm Oil Mill Effluent (POME) is discharged in huge amounts daily through processes of steralisation, crude oil clarification and cracked mixture separation. These highly polluting processes have a Global Warming Potential 21 times that of carbon dioxide. This poses as a critical issue for palm oil mill owners as the emissions are harmful to humans and the environment.
Seizing the opportunity to transform POME into power, Cenergi partnered with Havys Palm Oil Mill to develop a 2 MW biogas power plant with the mill. Operating under a 13-year Build-Own-Operate-Transfer (BOOT) agreement, the project uses anaerobic digestion to recover biogas from the POME supplied by Havys Palm Oil Mill.
The in-ground anaerobic digester typically generates 1,000 – 1,200 m3 of raw biogas per hour, which is then scrubbed to remove hydrogen sulphide and transmitted through a dehumidifier system to reduce its moisture content. This treated biogas is then channelled to 2 x 1,063 kWe Jenbacher engines to produce electricity and exported to the national grid through a Renewable Energy Power Purchase Agreement (REPPA) with Tenaga Nasional Bhd.
Qualified as a renewable energy feed-in tariff (FiT) programme by the Sustainable Development Authority of Malaysia (SEDA), Havys has generated enough electricity to power over 4,000 households per month since its operations began in August 2013. The plant not only supplies electricity to the community, but also provides employment opportunities to local talent and reduces carbon emissions. Havys is celebrating its 5-year operational anniversary this August 2018.
As Cenergi’s first biogas power plant, Havys represents a significant milestone in our move towards a sustainable future. In the next five years, Cenergi aims to have 20 commercially viable biogas plants in Malaysia and to continue to expand into Southeast Asia. In addition to increasing its geographical reach, Cenergi will also be exploring and building on alternative clean energy sources, including solar and mini hydro.
