If you believe in the tooth fairy, or vote Green, you probably believe that hydrogen is the magic rainbow gas that will banish global warming, replace wicked hydro-carbons in electricity generation, fuel tomorrow’s trucks, planes and heavy equipment, and earn unlimited export income.

There is one big problem – unlike coal, oil and gas, there are no hidden pools of hydrogen we can tap. Every bit of hydrogen has to be manufactured from water or hydrocarbons using huge amounts of energy.

The energy content of liquid hydrogen is about 70% of the energy required to produce it.  Burn it in a combined cycle gas turbine (energy efficiency 50%) and see that energy return drop to around 35%. Use it as vehicle fuel and see energy efficiency fall even further.

The density of liquefied hydrogen is much lower than that of natural gas - thus the transportation costs will be higher. And because the tiny hydrogen atom finds any small leak, the safety risks are very high - imagine a road accident involving flammable lithium batteries plus explosive hydrogen gas.

Most hydrogen is made directly from coal, oil or natural gas and the main process produces hydrogen and . . . more of the dreaded CO2.

But hydrogen is loved by Big Greens and little children because it has been named in a rainbow of pretty colours: grey, brown, black, green and blue.

Grey hydrogen comes from natural gas, brown from lignite (brown coal), and black hydrogen is made from black coal (no surprises there).

Green hydrogen is produced by electrolysis of water using intermittent green energy like solar or wind power. It requires heaps of fresh water and electricity neither of which can ever be fully recovered. Every tonne of hydrogen uses nine tonnes of water.

Blue hydrogen is any of the above but the CO2 by-product is stored in carbon cemeteries, making blue hydrogen stupidly expensive.

La Nina Floods have mangled the roads of eastern Australia with pot-holes, gully wash, mud and silt.

President Zelensky hopes to “one day” host the song contest in Mariupol, currently controlled by Russia.

Kalush Orchestra music band has won the Eurovision Song Contest 2022, after making a plea from stage to help save Ukrainian fighters holed up in Mariupol, and receiving landslide support from European public in phone and online vote.

Long before the Wuhan coronavirus (COVID-19) was ushered in as a global plandemic, psychological terrorists from the United Kingdom were quietly invading Australia and New Zealand and manipulating their respective governments into setting up “nudge teams” to influence public sentiment about things.

 These days it seems that Saul Alinsky has taken over the Democrat Party. This is no longer the party of JFK—not even close. JFK said in his Inaugural Address, “the rights of man come not from the generosity of the state but from the hand of God.”

There is no God, says Saul Alinsky (1909-1972), the Marxist community organizer par excellence from Chicago. He perfected many of the “by any means necessary” tactics the left is using today—tactics on full display these days in the wake of challenges to Roe v. Wade.
