However, according to ACCR’s filing, Santos internal documents said hydrogen could only be produced at that price if the gas used cost about $4 a kilogram, and Santos did not “have a line of sight” to such a cheap supply, and the product would not be zero emissions.
The filing said Santos also assumed it could sell blue hydrogen and claim offsets for reducing its customer’s emissions. This would likely be double counting of emissions savings.
Other Santos documents described some claimed emission reductions as “speculative”, “nominal” and “notional”. The ACCR filing quoted a document that described the significant contribution of “CCS expansion” to emissions reduction in the Santos plan as “a nominal number making up the difference” to achieve net-zero emissions.
Santos assumed it could fill natural gas pipelines with up to 50 per cent hydrogen when it had no reasonable basis for assuming more than 10 per cent, according to the filing.
Santos declined to respond to questions.

Longo told The Australian Financial Review that ASIC was already investigating one publicly listed company for greenwashing.
