The Northern Tasmania Development Corporation has been highlighting the deep-water port's potential for green hydrogen generation and exports, but fears Tasmania is being left behind by mainland states.

The hydrogen market is predicted to reach $215 billion globally in just three years, and Queensland has already released a $19 million green hydrogen strategy to utilise solar power, while Western Australia has launched a $10 million renewable hydrogen fund.

NTDC chair John Pitt said as Australia's renewable energy capital, the Tasmanian Government should be leading rather than following when it comes to green hydrogen.

"It looks as if this is being delivered off the side of the desk rather than with properly configured resources and adequate funding to develop a long-term strategic map for the globally-competitive facility that we want to see," he said.

"Our concern is that we could be moving much more publicly and overtly to declare our interest and commitment to participating in the hydrogen economy.

"The milestone agreement we're particularly keen on would be a commitment to facilitate the development of a small-scale plant at Bell Bay by 2022."

Asian markets are increasingly turning to hydrogen as an energy source in the shift away from fossil fuels.

It requires the use of renewable energy to electrocute drinking water, splitting it into hydrogen and oxygen, to be exported as liquid hydrogen.

Bell Bay's access to cheap power, drinking water and a deep-water port made it an ideal location for a large-scale export hub that could employ 500 people.

Four global companies are already believed to be investigating Bell Bay. Mr Pitt said governments could play a role through "blended financial arrangements" and by helping in the establishment of a small-scale facility.

Labor fears hydrogen production was moving ahead in other states and territories - including South Australia and Northern Territory.

Labor energy spokesperson Mark Butler visited Bell Bay on Wednesday, and said it made sense for Tasmania to be a leader in the field.

"[This is] an industry that in the short to medium term could create 500 jobs and earn very substantial income for this state, leveraging off not just the renewable capacity here in Northern Tasmania, but the extraordinary commercial and transport links that this part of Tasmania - Bell Bay in particular - has with Asia that is so thirsty for Australian hydrogen," he said.

Tasmanian Labor energy spokesperson David O'Byrne said Tasmania was the only state recognised as a potential location for hydrogen production that was yet to have an action plan or strategy.

While Labor claimed the Tasmanian Government had not participating in two recent national strategic meetings with Professor Alan Finkel, the government responded that it had, in fact, met Professor Finkel last month.

Energy Minister Guy Barnett said Tasmania was "actively involved" in the development of the National Hydrogen Strategy, due to be released later this year.

He said Tasmanian representation had been "at all levels in the development of this strategy".

"The Tasmanian Government recognises the significant economic benefits of a large-scale hydrogen production industry - which is why we are actively advancing a number of opportunities, which leverage our key competitive advantages and the Bell Bay port," Mr Barnett said.

Liberal Bass MHR Bridget Archer said it was unhelpful for Labor to "politicise" the issue.

"While I understand that there is some uncertainty surrounding Temco's plans, it's important that due diligence is conducted by all stakeholders to find the most appropriate way forward in a range of future opportunities, including hydrogen production, and that work is currently being undertaken," she said.
