The government of Papua New Guinea (PNG) has entered into a joint venture with a national power producer in a project to bring additional power generation capacity to the island nation. The system will use a process using liquefied natural gas (LNG) and could eventually be converted to run on hydrogen as fuel.
On July 12, Singapore-based Twenty20 Energy announced that it would be rolling out its Power Island Floating Storage Regasification & Power, or FSRP, solution to a dozen locations across Papua New Guinea as part of the PAWA project. PNG. Twenty20 supports the joint venture between the government and Dirio Gas & Power, an independent power producer in PNG that focuses on natural gas installations.
PAWA PNG will supply 283MW of what officials said is a “cheaper and more reliable” electricity supply, with lower emissions, as it mostly replaces older diesel fuel-based power generation. The project is designed to bring additional electricity to areas where it will support economic and social development goals.
Twenty20 Energy said on Tuesday that its proprietary Power Island FSRP comprises three components, supported by what it called a “complete LNG fuel logistics solution.” Components include FSRP power barges, which include power generators and regasification equipment, and where power generation from gas turbines and waste energy takes place. The system also includes fuel barges, which feature LNG storage tanks that supply gas turbines with fuel. The barges have 30 days of LNG supply and are the remote fuel bunkering solution.
The system also includes floating docks, which will moor barges at each of the 12 locations.
“Our Power Island FSRP design takes advantage of the abundance of locally produced LNG in Papua New Guinea, providing a cost effective and environmentally friendly solution for power generation for coastal communities,” said Geoff Lawrence. , CEO of Twenty20 Energy. “The adoption of the technology in Papua New Guinea demonstrates that the Power Island FSRP should be an attractive solution for similar coastal and island communities in the Asia-Pacific region and globally.”
The Power Island Project will provide a solution designed and tailored specifically to Papua New Guinea’s energy needs. The project represents what Twenty20 Energy and PNG officials have called the most efficient and cost-effective solution to harnessing the country’s domestic LNG supply to power the country, while supporting the electrification goal of 70 % by 2030. Officials estimate that only 13% of PNG’s population has access to electricity, mostly in major cities. Electricity in remote parts of the country is usually provided by stand-alone diesel generators.
Floating docks at 12 sites
Twenty20 Energy’s design calls for the construction and transport of floating docks to 12 different sites. Electric barges and fuel barges will be built and transported to the floating docks, where they will be moored. When in need of additional fuel, the fuel barges will travel to one of three LNG bulk storage centers, where they will be filled and returned to the floating jetty.
The 12 energy islands will be located just offshore, outside of a dozen cities. Three locations considered more strategic – Daru, Lae and Lihir – will also host bulk LNG storage facilities. The other nine locations are Manus Island, Buka Town, Kimbe, Alotau, Madang, Rabaul, Wewak, Kiunga, and Kikori.
The Twenty20 FSRP includes two specific unit sizes with different outputs, ranging from 8.6 MW to 21.9 MW, which will be used in each location. Each island of power can be modified as it grows, so as a location grows, a larger unit can be brought in, with the smaller unit able to be moved to a new location.
Twenty20 Energy began designing the Power Island FSRP in 2018, and the company has since conducted both a comprehensive technical and commercial study, as well as an independent technical assessment to confirm the validity of the design. Twenty20 said its intellectual property includes its plant and ancillary setup, combining power generation, fuel storage and bunkering, and transportation. “The design requires minimal land use and is ultimately mobile to meet near-term and future expansion needs,” the company said, noting that going forward, “Power Island’s FSRP solution can be converted LNG into hydrogen fuel, which is completely renewable and provides carbon-free electricity generation.
“This PAWA PNG Power Island project has provided decades of clean, reliable electricity to many citizens of PNG using locally sourced and generated energy,” said Augustine Mano, Managing Director of the Mineral Resource Development Company ( MRDC). MRDC is a wholly state-owned company created to hold and manage provincial government and landowner interests in mining and petroleum development projects. “This will help the PNG government ensure national energy security and independence while improving the lives of the people of PNG through the provision of reliable and cost-effective electricity supply,” Mano said.
