A Stewart Island Energy Forum

An unmoderated forum to share information on energy problems and solutions for Stewart Island - all contributions and comments will be published. If you are submitting a link please include a brief description of the contents. Names will not be published unless specifically requested.

There will be a workshop on Stewart Island's Energy Future held at the Community Hall on the 24th of February commencing at 12:30 p.m.

Please make the effort to attend if you are interested in our future energy supply options.

Comment received on the above from H Cave, Stewart Island
Will we have figures of the cost of a cable from the mainland, or information about progress on this? This needs to be presented (facts, not wild guesses) so we can measure it against the other options

Comment received from BASIL WALKER of REAL GREEN ENERGY
I note your introductionis for Hydrogen fuel cells.
That is not correct
please replace with;

DIESEL/PETROL ENGINES & GENERATORS FUEL SUBSTITUTION using HHO produced
on demand FOR GENERATOR SET + AUTOMOBILES + MARINE VESSELS.

Comment recieved on the above from G Lawrence S.I.

I agree Emec is a great facility and Orkney is an ideal location to test and promote renewable energy, it’s windy (see: http://www.orkneyjar.com/orkney/climate.htm), it has a reasonably high wave energy potential (see: http://www.emec.org.uk/EWTEC7_EMEC.pdf) and its able to offset the detrimental effects of intermittent power generation due to its connection to the UK national grid, with two power cables to the Scottish mainland and a third cable underway. Shetland is looking in the same direction (no land sheltering so wave energy potential) and expects to have a subsea cable connection by 2016 (see: http://www.oceanpowermagazine.net/2011/11/16/vattenfall-signs-mou-with-shetland-islands-for-marine-energy-development/). Although bodies such as Venture Southland see marine energy deployment 10 to 15 years away and a high risk investment before then ( see page 78: http://www.southlandnz.com/Portals/0/Documents/Business/Industry%20Profiles/Southland%20Energy%20Strategy%202011.pdf ) it could be possible for the Island to capitalise on experimental renewable technology if cable connection became a reality.

Comment received on the above

"This article was last revised in 2006 so it is somewhat out of date, it does give a good insight into the technology and its inherent problems but I was wondering if anybody could suggest something a bit more up to date? Most reputable sources seem to suggest that a workable solution is ten years away at the very least. I doubt that we could ever produce such a fuel on the Island and the logistics of tranporting such a highly compressed, volatile and low density product would be horrendous."
