Recycled Lithium-Ion Batteries Can Perform Better Than New Ones: A novel method of recycling such batteries could help meet skyrocketing demand
There is a ‘goldrush’ by petrochemical companies currently going on in South Australia where they are looking to stake claims on and prove the existence of underground reserves of nearly pure hydrogen gas. The article touts a “Potential to drastically cut costs” of hydrogen production.
Despite the lack of research, Australians – and indeed a number of companies internationally – remain undeterred, likely because of the potential for natural hydrogen to be three to four times cheaper than that produced via electrolysis or gas reforming with carbon capture. Gold Hydrogen estimates it should be able to produce natural hydrogen for less than $2.30 per kg, compared to manufactured hydrogen projects being produced at greater than $6 per kg.

South Australia has found itself at the heart of a 21st-century gold rush, though this time for naturally occurring hydrogen. Since February 2021, 18 exploration licenses have been granted or applied for in the state by six different companies searching for natural hydrogen
In a rapid escalation from zero activity in February last year, exploration companies are now scrambling to look for what they believe could be the cheapest, easiest way to get their hands on the much hyped “future fuel”: hydrogen.
In the last 12 months, six different companies have either been granted or applied for 18 Petroleum Exploration Licences across the state of South Australia, according to Australian energy consultancy EnergyQuest. Combined, the area under permit equates to around 570,000 square kilometres (km2) or 32% of the entire state, the consultancy has found, referring to the sudden influx as a “boom”.
Natural hydrogen
Until now, natural or native hydrogen has been largely overlooked – despite it being described as “widespread in nature” by natural hydrogen researcher Viacheslav Zgonnik in a 2020 paper. Natural hydrogen deposits form through chemical reactions underground, with Zgonnik saying the molecule has been detected at high concentrations, often as the major gas, in all types of geologic environments.

Caveat emptor. This could be good news in that a potential source of low or zero emissions hydrogen for power generation has been found that could replace natural gas. However, I suspect that most or all of the hydrogen will found to be associated with methane rich natural gas. My guess is that this will be used as an excuse by the fossil fuel industry members funding the exploration to produce and burn more natural gas with consequent greenhouse gas emissions going into the atmosphere.
I would watch this very carefully, and would hope that by the time any concrete decisions need to be made regarding real hydrogen production projects that we will have replaced Capt. Humbug’s LNP Coalition Government with trustworthy people able to make sensible decisions where project approvals and he like are concerned.

Clearly, we wont know if we have passed the point of no return until it is too late to do anything about it. Spratt’s concluding comments to his guidebook need no embellishment from me. He lists 7 points. Basically I agree with all of him, except that I would state several of them even more strongly than he does:

Reflecting on the evidence presented in this tipping point series, a number of conclusions may be drawn:
1. At just 1.2°C of warming, tipping points have been passed for several large Earth systems. At just 1.2°C of global average warming, tipping points have been passed for several large Earth systems. These include Arctic sea ice, the Greenland Ice Sheet, The Amundsen Sea glaciers in West Antarctica, the eastern Amazonian rainforest, and the world’s coral systems. The world will warm to 1.5°C by around 2030, with additional warming well beyond 1.5°C in the system after that. Yet even at the current level of warming, these systems will continue to move to qualitatively different states. In most cases, strong positive feedbacks are driving abrupt change. At higher levels of warming, the rate of change will quicken. The meme that “we have eight years to avoid 1.5°C and tipping points” should be deleted from the climate advocacy vocabulary. It is simply wrong.

2. System-level change is happening faster than forecast. In each case surveyed above, abrupt change is happening earlier and/or faster than projected only two decades ago. The 2007 Arctic sea-ice collapse was “100 years ahead of schedule”; in 2014 the tipping point for Amundsen Basin glaciers was one that “none of us thought would pass so quickly”. It was said that the guardrail for coral reefs was warming under 2°C, then 1.5°C; it is now clear that it is under 0.5°C. In 1995, the IPCC projected “little change in the extent of the Greenland and Antarctic ice sheets… over the next 50-100 years”. The 2001 IPCC report suggested that the Greenland and the West Antarctic ice sheets would not lose significant mass by 2100. Both have now passed their tipping points. The effect of the permafrost carbon feedback has not been included in the IPCC scenarios, including the 2014 report. And on it goes.
In this now completed series of posts, Spratt has done an excellent job of summarizing the scientific observations that sound the klaxon fire alarm warning us that our planet is on fire. If we don’t wake up, smell the smoke, and mobilize global action to fight the fire, it will consume us humans along with most other complex life who share the still green(ish) planet with us.
Following on from Tony Abbott’s almost religious commitment to denying climate science, Scotty’s marketing backed up by his troop of puppets, buffoons, and knaves in Parliament have been for years almost totally successful in blocking any effective action against the climate emergency. This has been achieved through a rich mix of humbug, denial, lying, misrepresentation, blocking, delaying, and distracting smoke and mirrors.
If our children and grandchildren are to have any hope of surviving into the future, we have to remove the humbug troop from Parliament and replace them with sensible people who can be trusted to put action against the climate emergency at the top of their priority lists if elected. Vote Climate Ones, Traffic Light Voting System is designed to help you rank your preferences to do this, without telling you who you should vote for. With a new Parliament focused on what needs to be done to protect our burning house, we might be able to offer our families a viable future in a still functional biosphere.

Labor’s plan to green the Kurri Kurri gas power plant makes no sense
“The increasing incidence of wildfire in the Arctic is not only thawing permafrost but also changing the entire underlying structure of the region.” The net result is to greatly increase the rate of thawing and the amount of greenhouse gases being released to the global atmosphere (which is why it concerns us here in Australia!)
The bottom line is that if we humans don’t stop the continuing increase in global temperature (global warming) it will soon be impossible to do so because of the exponentially increasing positive feedbacks from temperature sensitive greenhouse gas emissions like this. This is the threshold, or point of no return, beyond which our planetary climate system is fully committed to complete its flip into the hothouse hell state. (see Steffen et al. 2018, Trajectories of the Earth System in the Anthropocene and my own 2021 research presentation, Portents for the Future – 2020 Wildfires on the Siberian Permafrost.)

The Anaktuvuk River Fire in 2007 tore through 100,000 hectares of Alaskan tundra in almost 3 months of continuous burning. This fire not only changed the area vegetation, but it also thawed permafrost and led to the formation of thermokarst. This is a dramatic example but may serve as a bellwether incident for climate to come.
“Almost everything hinges on permafrost in the Arctic ecosystem.”
Arctic permafrost stores 33% of Earth’s organic carbon, even though it covers only 20% of the planet. It also acts as the structural foundation, physically and ecologically, for the entire pan-Arctic region. Permafrost thawing has cascading effects on the hydrological conditions of the landscape and ice and also triggers changes in vegetation and releases stored carbon. “Almost everything hinges on permafrost in the Arctic ecosystem,” said Yaping Chen, a postdoctoral research associate at the College of William and Mary’s Virginia Institute of Marine Science.
Yet there are still questions about how fires (the incidence of which is increasing in the Arctic) and climate change might increase the amount of thermokarst—the uneven land formed after permafrost melts. Thermokarst is the result of the degradation of permafrost and provides reduced carbon sequestration and fewer niche ecosystems than permafrost.
…
“Our major result is that although fire only burned about 3% of the Arctic landscape, it is responsible for more than 10% of thermokarst formation,” said Chen. “However, climate change remains the predominant regional consideration of thermokarst formation.”
Researchers also found that fires increased thermokarst formation for up to 80 years postfire, much longer, said Chen, than previously thought.
We have poor knowledge about the presence of permafrost, said Chen. We don’t know exactly where it is or how much there is of it. “These difficulties make it very hard to predict where thermokarst may start and how it will develop over time,” she said.

Humanity has only a few years at the most to stop and reverse global warming. If we fail to do this our children and grandchildren will have no future in the global mass extinction in Earth’s Hothouse Hell. Currently stifled and mesmerized by the humbug, lies, blocking and misdirection of the LNP COALition’s fossil fuel puppets, Australians are doing nothing effective to fight the warming fire that is burning up our only planet.
To have any hope of contributing to the solution, we must replace Capt. Humbug (a.k.a., Scotty from Marketing), his deputy dunce, Blarny Bulldust (The Man with the Hat), and their troop of wooden headed puppets occupying our Parliament with sensible people committed to acting on the climate emergency as their first order of business if elected to office. Vote Climate One’s Traffic Light Voting System is designed to help you replace the special interest puppets with good people who will help put out the fire rather than trying to con us into believing that it doesn’t exist…., or if it does, that it isn’t important….
