Efforts to get a tidal power project up in north west WA still seem to be continuing, although haggling over the definition (tidal vs hydro) shows that not much progress is being made - Tidal power or hydro power in Derby.
The tides at Derby in the Kimberly region of Western Australia rise and fall up to 11 metres.
This volume of moving water involves an enormous amount of power which, for decades, people have tried to harness.
The last plan was shelved eight years ago due to environmental and financial concerns but now the scheme is back on the agenda.
With a price on carbon making low polluting electricity generation attractive and plans for more development in the area, there is renewed push for a tidal energy project.
But the plan involves damming two arms of Doctor's Creek and therefore opponents consider it a new hydro power project and not a tidal power project. This will affect the project's ability to earn carbon credits.
