Off Grid Energy Independence

Escape from diesel

Transparent Conductive Films and Materials 2018
For all the obvious reasons, sales of diesel cars are in freefall and diesel gensets are just beginning to be used less and increasingly replaced by zero emission alternatives. That starts with the combination of massively intermittent solar or wind power balanced by huge batteries. It progresses to combining sources with complementary intermittency or using virtuously continuous sources such as the new tidal stream and wave power with no infrastructure and Aerial Wind Energy - tethered drones tapping the stronger, more consistent winds well above wind turbines. In each case energy storage is minimal or non existent. Surprisingly often, this involves cost and outage reduction not just emission reduction.
 
 
Here is an example of the beginning of the process with the grid on the island of Tasmania Australia and adjoining islands. It is reported by Canberra Times:
 
Bruny Island solar trial a microcosm for future
A smart solar and battery trial on an island off Tasmania is being touted as creating the forerunner for Australia's energy future. Lachlan Blackhall, head of the Australian National University's battery storage and grid integration program said the trial, carried out with 40 households on Bruny Island off the coast of Tasmania, was designed to create a microcosm of a future Australian electricity grid.

Led by the Network Aware Coordination (NAC) platform - a series of smart algorithms that control multiple solar and battery installations to push power into the grid when it is needed - the trial allowed Australians to tap into the grid and become power producers themselves, earning money while the sun shone.
 
The Bruny Island trial saw a combination of solar and battery installations work cooperatively to replace diesel generation. The battery project was not focused on replacing the main power sources, but on supplementing them and reducing the island's reliance on diesel generation during summer and other periods of peak demand.
 
"The trial of the NAC is about better understanding how to use solar and battery to make the grid more efficient," Mr Blackhall told Fairfax Media. "During Easter, Bruny Island actually required more power than could be supplied by the undersea cable to the island. Typically they would use diesel but this program - even with only 3.5 per cent of homes on the island participating - reduced diesel usage by 30 per cent."
