ADNOC has agreed to supply Osaka Gas with up to 800,000 tonnes per annum (tpa) of liquefied natural gas (LNG) from its lower-carbon Ruwais LNG project.

This 15-year sales and purchase agreement (SPA) marks the first long-term LNG sales agreement between ADNOC and Osaka Gas. It is the fourth SPA signed for Ruwais LNG.

The LNG will be sourced from the Ruwais LNG project in Al Ruwais Industrial City, Abu Dhabi. The project is expected to commence operations in 2028.

Under the agreement, LNG cargoes will be delivered to Osaka Gas and its Singapore-based subsidiary, Osaka Gas Energy Supply and Trading.

ADNOC senior vice-president marketing Rashid Khalfan Al Mazrouei said: “This agreement with Osaka Gas reinforces our long-standing energy partnership with Japan and supports our strategy to expand our global LNG footprint. Through our world-class Ruwais LNG project, ADNOC will continue to provide more lower-carbon gas to meet growing global demand, fuel industries and power homes.”

International buyers in Asia and Europe have committed to purchasing up to eight million tonnes per annum (mtpa) of the Ruwais LNG project’s 9.6mtpa capacity through long-term agreements.

The Ruwais LNG plant will also be the first in the Middle East and Africa to operate on clean power, aiming for low-carbon intensity.

The facility will utilise AI and advanced technologies to enhance safety, minimise emissions and improve efficiency.

Osaka Gas executive vice-president Keiji Takemori said: “The relationship between Abu Dhabi and our home base Osaka dates back to 1970, marked by the opening of the Abu Dhabi Pavilion at the Expo’70 in Osaka.

“This year, Osaka once again hosts the World Expo, and we are delighted to announce the signing of a long-term LNG sale and purchase agreement with ADNOC in this landmark year. ADNOC has been a reliable LNG supplier to Japan for nearly half a century. This new contract, with such a trusted LNG provider, will help ensure a stable energy supply for our customers.” 

ADNOC Gas announced plans last November to acquire ADNOC’s 60% stake in the Ruwais LNG project by the second half of 2028, with an estimated transaction value of $5bn (Dh18.36bn).

The project will include two 4.8mtpa liquefaction trains, doubling ADNOC Gas’ LNG production capacity to approximately 15mtpa.

In February 2025, ADNOC completed a marketed offering of 3.1 billion ordinary shares in ADNOC Gas to institutional investors.

This increased the free float and set the stage for possible inclusion in international indices such as the MSCI Emerging Market Index and the FTSE Emerging Market Index.
