Bill Oplinger reassured investors that a 15-month delay would not affect operating rates at its Pinjarra alumina refinery but misled them about Alcoa's record of rehabilitating the jarrah forest.
Several big green hydrogen projects have been shelved. An expert explains why Australia’s sky-high ambition for the industry is struggling to reach fruition.
The WA environment regulator is investigating unknown amounts of hydrocarbons rising to the surface on the Class A nature reserve.
Chevron's CO2 injection on Barrow Island for the Gorgon LNG project is WA's only carbon capture and storage project. It is the world's largest CCS project dedicted to burying greenhouse gases, not increasing oil production.
Whether the facility can be used for carbon storage or has to be decommissioned has billion-dollar implications for Santos and its partners.
The idea is one of many around Australia that would delay the cost of decommissioning old infrastructure.
Carbon storage has gone from "high-risk" to the preferred option at the controversial gas export mega-project.
Australian LNG producers are under pressure on emissions and decommissioning, and Santos wants to tackle both problems in one swoop at Bayu Undan, but it needs everyone to play along.
On July 18 Chevron will be millions of tonnes short of required CO2 injection at Gorgon LNG. If the WA Government stands firm the carbon credit bill could approach $100 million.
Chevron's Gorgon should be a showpiece of carbon capture and storage but five years after first LNG it is still not working properly and has another five-month extension from the regulator.
Shell, Exxon and Chevron are big players in Australian oil and gas and being forced to decarbonise sooner will affect their local operations, with a possible king hit to Prelude.
In this week's budget the Morrison Government ignored clean energy and instead took a long-odds bet that carbon capture and storage will allow fossil fuels to carry on untouched by climate concerns.
If CO2 from Yara's Pilbara ammonia plant is buried WA could ship a clean fuel to displace coal in JERA's Japanese power stations, but underground carbon storage has its doubters.
Santos and ENI are looking for solutions for CO2 and removing old facilities in the waters north of Darwin. Time will tell if the problems are solved or just delayed.
The cost of storing CO2 produced when hydrogen is made from coal or gas will likely make blue hydrogen uncompetitive against green hydrogen made with renewable electricity, ANU scientists conclude.
Ichthys LNG is giving Inpex and Australia a huge carbon pollution problem that is likely to grow as the Japanese company looks to troublesome carbon capture and storage to limit the environmental and financial damage.
