South Australia has run aground on the long foreseen wind energy reef - is this a lee shore?

Those of you who have followed my energy commentaries published here over the past six years will know that this situation was the entirely predictable outcome of South Australia pressing on with an unrealistic renewable energy target dependent on wind generated electricity, subsidised by market distorting Large-scale Generation Certificates (LGCs) (previously called RECs in some places on this website - the name was changed after their publication).

Since I first published an article on this subject I've been taken to task by a young family member for being too negative about the prospects of a Hydrogen Economy, mainly because I failed to mention 'clean green hydrogen' generated from surplus electricity, employing electrolysis.

Back in 1874 Jules Verne had a similar vision but failed to identify the source of the energy, 'doubtless electricity', required to disassociate the hydrogen and oxygen. 

Coal; oil and gas; peat; wood; bagasse; wind; waves; solar radiation; uranium; and so on; are sources of energy.  But electricity is not. 

Electricity (and hydrogen derived from it) is simply a means of transporting and utilising energy - see How does electricity work? on this website.

Introduction

 

The present government interventions in electricity markets, intended to move the industry from coal to renewable energy sources, are responsible for most of the rapidly rising cost of electricity in Australia.  These interventions have introduced unanticipated distortions and inefficiencies in the way that electricity is delivered.

Industry experts point to looming problems in supply and even higher price increases.

A 'root and branch' review of these mechanisms is urgently required to prevent ever increasing prices and to prevent further potentially crippling distortions.

The electrically literate may find this somewhat simplified article redundant; or possibly amusing. They should check out Wikipedia for any gaps in their knowledge.

But I hope this will help those for whom Wikipedia is a bit too complicated and/or detailed.

The Chimera‡ - also known as carbon capture and storage (CCS) or Carbon Sequestration

Whenever the prospect of increased carbon consumption is debated someone is sure to hold out the imminent availability of Clean Coal Technology; always just a few years away. 

I have discussed this at length in the article Carbon Sequestration (Carbon Capture and Storage) on this website. 

In that detailed analysis I dismissed CCS as a realistic solution to reducing carbon dioxide emissions for the following reasons:

Travel

Canada and the United States - Part1

 

 

In July and August 2023 Wendy and I travelled to the United States again after a six-year gap. Back in 2007 we visited the east coast and west coast and in 2017 we visited 'the middle bits', travelling down from Chicago via Memphis to New Orleans then west across Texas, New Mexico, Nevada and California on our way home.

So, this time we went north from Los Angeles to Seattle, Washington, and then into Canada. From Vancouver we travelled by car, over the Rockies, then flew east to Toronto where we hired a car to travel to Ottawa and Montreal. Our next flight was all the way down to Miami, Florida, then to Fort Lauderdale, where we joined a western Caribbean cruise.  At the end of the cruise, we flew all the way back up to Boston.

Seems crazy but that was the most economical option.  From Boston we hired another car to drive, down the coast, to New York. After New York we flew to Salt Lake City then on to Los Angeles, before returning to OZ.

As usual, save for a couple of hotels and the cars, Wendy did all the booking.

Australia's Hydrogen Economy

 

 

  

As anyone who has followed my website knows, I'm not a fan of using 'Green Hydrogen' (created by the electrolysis of water - using electricity) to generate electricity. 

I've nothing against hydrogen. It's the most abundant element in the universe. And I'm very fond of water (hydrogen oxide or more pedantically: dihydrogen monoxide). It's just that there is seldom a sensible justification for wasting most of one's electrical energy by converting it to hydrogen and then back to electricity again. 

I've made the argument against the electrolysis (green) route several times since launching this website fifteen years ago; largely to deaf ears.

The exception made in the main article (linked below) is where a generator has a periodic large unusable surpluses in an environment unsuitable for batteries. In the past various solutions have been attempted like heat storage in molten salt. But where there is a plentiful fresh water supply, producing hydrogen for later electricity generation is another option.  Also see: How does electricity work? - Approaches to Electricity Storage

Two of these conditions apply in South Australia that frequently has excess electricity (see the proportion of non-hydro renewables chart below). The State Government, with unspecified encouragement from the Prime Minister and the Commonwealth, has offered A$593m to a private consortium to build a 200MW, 100t hydrogen storage at Whyalla.  Yet, the State already has some very large batteries, with which this facility is unlikely to be able to compete commercially.  Time will tell.

Tragedy in Norway

 

 

The extraordinary tragedy in Norway points yet again to the dangers of extremism in any religion. 

I find it hard to comprehend that anyone can hold their religious beliefs so strongly that they are driven to carefully plan then systematically kill others.  Yet it seems to happen all to often.

The Norwegian murderer, Anders Behring Breivik, reportedly quotes Sydney's Cardinal Pell, John Howard and Peter Costello in his manifesto.   Breivik apparently sees himself as a Christian Knight on a renewed Crusade to stem the influx of Muslims to Europe; and to Norway in particular.
