House of Assembly Fifty-Fifth Parliament Parliament, First Session (55-1) 55 1 Parliament of South Australia House of Assembly published Question Time Hydrogen Sector Hydrogen Sector Mr PATTERSON House of Assembly Morphett Hydrogen Sector Mr PATTERSON (Morphett) (15:20): My question is for the Minister for Energy and Mining. Does the minister stand by his estimate that the cost for liquification and storage of 3,600 tonnes of hydrogen in his hydrogen plan will be $31 million? With your leave, sir, I will explain. Leave granted. Members interjecting: The Speaker House of Assembly The SPEAKER: Order! Mr PATTERSON House of Assembly Mr PATTERSON: The Grattan Institute has advised that the actual cost will be in the low hundreds of millions of dollars? The Hon. A. KOUTSANTONIS House of Assembly West Torrens Minister for Infrastructure and Transport Minister for Energy and Mining The Hon. A. KOUTSANTONIS (West Torrens—Minister for Infrastructure and Transport, Minister for Energy and Mining) (15:20): They are not my estimates. They were the estimates of Danny Price and Frontier Economics. The former government were claiming that the power plant would run operationally 24/7, requiring a much larger level of storage. I understand that's how they have come to these costs. We dispute those costs. I trust Frontier Economics and Danny Price, not a Collingwood football player.
