MEPAU’s Vision for Low-Carbon Energy Future

MEPAU is proud to be a part of the next generation of energy businesses that are actively transitioning to a low-carbon energy future. We are committed to a collaborative and flexible pathway to rapid decarbonisation which promotes innovation and emerging best practice technologies, such as carbon capture and storage (CCS) and ammonia as a fuel source replacing thermal coal.

A Collaborative Approach

Our customers and stakeholders remain central to our approach. As a trusted and reliable business partner, MEPAU is making progress alongside our stakeholders to meet the energy needs of the future.

In 2021 we announced a joint feasibility study with the Japan Oil, Gas and Metals National Corporation (JOGMEC) to collaboratively investigate CCS opportunities in Western Australia associated with MEPAU’s Perth Basin investments.

In 2022 we welcomed the announcement of $20 million from the Australian Government to kick-start the establishment of a Mid West Modern Energy Hub. The Hub will also be a key component in MEPAU’s efforts to support its customer’s transition to a low-carbon economy.

MEPAU’s Mid West Modern Energy Hub

MEPAU as a subsidiary of Mitsui & Co. has the credibility, capabilities and global network to execute projects for the benefit of the Mid West, Western Australia and our customers. MEPAU’s Mid West Modern Energy Hub is the natural next step for the Mid West, which has been providing energy to the domestic market for fifty years.

The Mid West Modern Energy Hub supports rapid decarbonisation and supports a low-carbon energy future. The Hub provides a pathway from natural gas and LNG to blue ammonia and hydrogen supported by carbon offsets and storage.

A Pathway to Rapid Decarbonisation

Carbon Capture and Storage (CCS) is an important part of the pathway to a low-carbon energy future. It enables rapid decarbonisation and emissions reduction by utilising a combination of technologies to capture and store large volumes of carbon dioxide in order to prevent its release into the atmosphere.

CCS involves three steps: capture at source, transport of the carbon dioxide, and injection of the carbon dioxide into rock formations deep underground for safe storage.

Government Regulatory Controls

We work with a multitude of government departments. Find out more about government regulatory controls.

Risk Management

What we do at Mitsui E&P Australia

What we do

We are actively exploring, appraising, developing and producing oil and gas in a number of locations in the northern Perth Basin. Read more about what we do


We look for gas, and when we find it we figure out if it’s worth pursuing further. Find out more about our exploration and appraisal process.


Once we’ve confirmed a well is commercially viable we get ready to put it into production. Read more about the development process.


During the production phase we produce gas from the well and sell it. Find out more about the production process.

Decommissioning and Rehabilitation

When the exploration or production activity has finished it’s time to clean up. Read more about how we decommission and rehabilitate a well and its surrounding area.

The Northern Perth Basin

The northern Perth Basin is a prolific oil and gas producing area covering a large portion of the Mid West region of Western Australia. The town of Dongara, located approximately 360km north of Perth, is the regional economic hub for a number of energy industries.
