Wärtsilä to develop Indonesia's first bio-LNG plant

Wärtsilä has signed a joint development agreement with two Indonesian partners to develop the first biogas liquefaction (bio-LNG) plant in Indonesia.

The co-signers of the agreement with Wärtsilä are national energy company PT Pertamina (Persero) and PT Godang Tua Jaya (GTJ), a waste utilisation sector specialist company.

Wärtsilä Oil and Gas Systems will conduct a feasibility study for the project to develop a mini bio-LNG plant with a capacity of 0.75 tonnes per hour, which corresponds to approximately 4MW/hour in electrical production.

The plant will process municipal solid waste into biogas for use as a renewable energy source for typical vehicle fuel. In addition to the feasibility study, Wärtsilä Oil and Gas Systems will provide technological support and an economic assessment. If the project is deemed to be feasible then the parties are expected to enter into an execution agreement.

'Renewable energy is an increasingly important global requirement,' comments Sanjay Verma, area sales director, Wärtsilä Ship Power.

Wärtsilä has also built a bio-LNG plant in Oslo, Norway. The plant converts 50,000 tonnes per year of household food waste into biomethane that is then used to fuel the local buses.
