Santos looks to hydrogen future through CCS

Santos Managing Director and Chief Executive Officer Kevin Gallagher said that natural gas can be decarbonised at its source to make “zero emissions” or “blue” hydrogen. The carbon dioxide produced as a result can then be safely and permanently captured and stored in the same reservoirs that the gas came from.

“The Cooper Basin hydrogen concept study builds on our progress towards the 1.7 million t Cooper Basin Carbon Capture and Storage Project for which Santos is targeting a final investment decision later this year, subject to a CCS methodology being approved for the Emissions Reduction Fund,” Mr Gallagher said.

“Carbon capture and storage (CCS) is the fastest and most efficient route to a hydrogen economy, using less water, decarbonising natural gas at its source, and eliminating Scope 3 emissions.”

“CCS enables the capture of carbon dioxide from the production of blue hydrogen, making it a zero emissions fuel.

“With over 65 years of experience in the safe production of natural gas, Santos has the operational knowledge, capability and infrastructure to be a leader in the creation of a hydrogen industry right here in Australia.”

Mr Gallagher said the development of blue hydrogen from natural gas in combination with CCS will be critical in our transition to a low-carbon future.

“A CCS and hydrogen future proves that emissions reduction and job-creating resource development can work hand-in-hand.”

GHD’s Chief Executive Officer Ashley Wright said GHD is at the leading edge of more than 25 projects spanning hydrogen production, storage and application in industries such as gas, ammonia, power generation and transportation.

“We are committed to supporting our clients through the global energy transition. We believe hydrogen could play a significant role in decarbonising industries and this project is a potential game-changer for the gas sector. We are proud to partner with Santos on this project, which draws on our hydrogen experience across Australia and globally,” Mr Wright said.

Santos’ proposed Moomba CCS Project in South Australia would capture the 1.7 million t of carbon dioxide currently separated from natural gas each year at the Moomba Gas Plant and reinject it into the same geological formations that have safely and permanently held oil and gas in place for tens of millions of years.

“With the Cooper Basin’s reinjection capacity assessed at up to 20 million t of CO₂/y for 50 years, it has the potential to decarbonise energy at its source,” Mr Gallagher said.

“This exciting opportunity could create high-skilled, well-paying and secure jobs, drive regional development, create new industries and deliver good outcomes for climate and the environment.”

Santos and GHD aim to complete the concept study by the end of 2020.
