The premier says the state government has no plans to follow Victoria's move to ban gas connections to new homes, though he hasn't totally ruled out the idea.
"It's not our policy as it stands," he told reporters on Monday.
"Decarbonisation of the gas network is another way of achieving the right outcome in terms of climate change without actually disconnecting gas networks or stopping connections in the future.
"That isn't us ruling out change but we've got a number of policies that we're pursuing in respect of hydrogen that help us achieve those decarbonisation objectives."
A trial is under way in Adelaide, blending small amounts of hydrogen into the home gas supply, and Mr Malinauskas said he understood it was going well and showed potential for expansion.
His comments came after the Victorian government said all new homes built from 2024 would not be allowed to have gas connections.
The changes will help the state reach its goal of net-zero emissions by 2045, and save residents with all-electric homes about $1000 a year.
About 80 per cent of Victorian homes are connected to gas, with the sector contributing about 17 per cent of the state's emissions.
The use of gas is smaller in SA, with a little more than 50 per cent of homes connected.
The Australian Pipelines and Gas Association criticised Victoria's decision, saying the government should instead introduce renewable gas like hydrogen into the system.
Environmental groups welcomed the ban, but NSW also ruled out taking similar steps.
Mr Malinauskas said the Victorian decision could result in more of SA's renewable energy being exported to east coast markets in coming years.
