Background

The Porto do Açu LNG terminal is part of the massive Porto do Açu port project on Brazil's Atlantic coast. Developed by GNA (Gás Natural Açu), a consortium formed by Prumo, BP, and Siemens, the terminal consists of a permanently moored FSRU (floating storage and regasification unit) with a regasification capacity of 21 million cubic meters per day and a storage capacity of 174,000 cubic meters. Initial plans called for the terminal to supply the 1338 MW GNA I power station and the 1672 MW GNA II power station in São João da Barra, which were scheduled to begin operating in 2021 and 2023, respectively.

The floating regasification unit (FSRU) BW Magna, purpose built for the Gas Natural Açu (GNA) LNG-to-power project, was commissioned by GNA from BW LNG. It was built in South Korea and scheduled for delivery by the South Korean shipyard DSME. The FSRU is designed for LNG transfer operations in ship-to-ship mode, with LNG to be imported periodically according to the needs of the Brazilian electrical system.

GNA has studied several future expansion options for the Porto do Açu facility, including doubling its regasification capacity with the addition of a second FSRU, adding storage capacity in the form of six LNG storage tanks with a capacity of 180,000 cubic meters each, enhancing distribution potential to Brazil's internal market by linking to the Gasene Gas Pipeline at Campo de Goytacazes, or supplying gas to additional power plants in Rio de Janeiro state such as the Norte Fluminense power station and the Marlim Azul power station.

The Porto do Açu terminal obtained its final installation license from INEA (Rio de Janeiro's environmental agency) in December 2018. The FSRU arrived at the Port of Açu in February 2020 and received its first imported LNG cargo from BP in January 2021.

Lithuania-based Klaipedos Nafta (KN Energies) was appointed as the operator of the Port of Açu LNG terminal onshore facilities. The LNG was to be supplied by BP, a shareholder of the GNA project along with Prumo Logistica and Siemens.

In 2023, KN Energies began working with BP to develop a new project allowing transport of LNG from a truck loading station at the Port of Açu to consumers not served by southeastern Brazil's gas pipeline network.

Regasification capacity

The Porto do Açu terminal was originally announced with a capacity of 5.6 mtpa, or 21 million m³ per day. However, reports from the terminal's owners have cited a wider range of regasification capacity, from 21 million m³ to 28 million m³ per day, or 1 billion cubic feet per day.

Plans for a new onshore terminal

During the inauguration ceremony for Gás Natural Açu's GNA II power station in July 2025, GNA and NTS (Nova Transportadora do Sudeste) announced they had formed a partnership to study the potential for an onshore LNG regasification and storage terminal at the Port of Açu, which would be connected to the national gas transportation network via the proposed Northern Fluminense Integration Gas Pipeline (GASINF). However, the companies did not disclose any specific details of the project under study.
