The state government recently released its renewable energy action plan, which outlined the steps towards its ambitious goal to double its output of renewable energy by 2040. A crucial part of the puzzle is the construction of the Marinus Link. This second undersea interconnector will allow Tasmania to produce renewable energy and send it whizzing across Bass Strait.

The Marinus Link is an ambitious project, supported by the federal government and has recently received another funding boost, to share in a $250 million package announced by Prime Minister Scott Morrison.

However, a dark cloud has hovered over the Marinus Link project nearly from its inception - and another grey cloud added to that maelstrom last week.

A new Victorian report, from the Victorian Policy Energy Centre, found battery storage would be a better cost-effective climate solution than the Marinus Link.

It proposed it wouldn't be a wise decision for the Victorian Government to pay for any share in the project's construction.

If the Victorians are distancing themselves from the Marinus Link project, more clarity is needed on the project's viability.

Renewable energy is a growing industry in Tasmania, but hinging the state's growth on one project seems short-sighted - significantly if the kinks on who pays for it still aren't ironed out.

Tasmania is making headway in the renewable energy space, but there needs to be room to grow with or without Marinus.

While it's likely the project will still go ahead, considering the important the PM places on it, but Tasmania deserves to be able to forge its own path, with or without Marinus. Our renewable energy targets rely on Marinus, but energy generation and targets are not the only way the state can move forward with nation-leading renewable energy projects.

Tasmania has always marched to the beat of its own drum - let's not stop now, when there's so much potential to move forward.
