New Zealand Tidal power station approved  

Posted by Big Gav in , , ,

The NZ Herald has an article on the slow progress of a tidal power project in NZ - Tidal power station for Kaipara approved.

More than half a billion dollars will be spent on sinking tidal power turbines to the seabed of the Kaipara Harbour after the approval of New Zealand's first tide-driven power station.

But the Environment Court has set conditions of consent for the project after a year of mediation among four objectors.

The key requirement for applicant Crest Energy is two years of environmental monitoring and evaluation and starting with only three turbines.

The company wants to sink up to 200 turbines off the harbour mouth in a $600 million plan to harness the swift tidal flow to power homes from Albany to Cape Reinga.

It appealed to the court in 2008 when Northland Regional Council allowed only 100 turbines to be sunk.

Scale, demand and location... a few microhydro projects I am helping on have amazing EROI, yet when the numbers between scale, location and demand diverge... so does the viablity.

Like the big $$$ hit and hard learning curve nations took on the big wind gamble... tidal projects have to learn by "what worked" for wind and model success to shift markets.

The potential for strong tidal is promising, but the sustainable energy markets can not afford to make the same mistakes that they did on wind. Otherwise investors will continue to bank on the mistakes of fossil fuels.

Many prove that you do not have to be smart to know how to make wind and tidal power work... few prove genius by making it profitable.


I'm not asking for a massive unicorn powered technology leap to save our future.

During the turn of the century in the U.S. local hydro and wind powered much of the start of the industrial revolution (before cheap oil and coal created unsustainable industrialization) ... and electric cars and public transport lined cities.

If the world truly wants a sustainable future, the historic path has proven prosperous.


P.S. Did you see the Air Force Researchers Claiming Wave Energy With 99% Efficiency? Wow 99% efficient that's a "dubious" energy claim I think I heard before ;-)
