Hydrogen gas stored for less than $3/kg may provide months of dispatchable power to cover intermittent green energy generation
by Emiliano Bellini, 14/02/2022 in PV Magazine
Hydrogen under $3/kg may ensure affordable seasonal energy storage in the US
Researchers from the United States have investigated how fuel cells and electrolyzers may be able to operate under intermittent availability provided by both wind and solar and have found that an affordable hydrogen-based system for seasonal energy storage could be achieved at a hydrogen price lower than $3, produced from inexpensive renewable electricity at $0.02/kWh.

There is significant evidence that the rate of global warming is already showing signs that it is at least partially being driven upward by positive feedbacks from temperature sensitive natural sources of carbon emissions. If so, it is unlikely that achieving zero emissions from human sources will be enough to do more than slow the rate of warming for a few years. To actually stop and reverse global warming we will have to actively remove greenhouse gas from the atmosphere (i.e., sequester them) at global scales. Ocean sinks for carbon might turn this task from a hopeful dream into reality.
My own unpublished studies of the literature relating to possible mitigation strategies to stop global warming prior to taking on my present VC1 role, suggested that fertilizing and farming the ocean deserts over abyssal depths should have the capacity to capture and sequester a significant fraction of the CO₂ in the atmosphere today. The recent research linked here suggests that significant carbon sequestration might be achieved by facilitating the growth of plankton with carbonate shells:
by Rupert Sutherland and Laia Alegret, 14/02/2022 in The Conversation
We think of trees and soil as carbon sinks, but the world’s oceans hold far larger carbon stocks and are more effective at storing carbon permanently.
In new research published today, we investigate the long-term rate of permanent carbon removal by seashells of plankton in the ocean near New Zealand.
We show that seashells have drawn down about the same amount of carbon as regional emissions of carbon dioxide, and this process was even higher during ancient periods of climate warming.
Humans are taking carbon out of the ground by burning fossil fuels deposited millions of years ago and putting it into the atmosphere as carbon dioxide. The current rate of new fossil fuel formation is very low. Instead, the main geological (long-term) mechanism of carbon storage today is the formation of seashells that become preserved as sediment on the ocean floor. [VC1 Editor’s emphasis]

The full scientific report on which the above article is based is also linked here for your easy access. There are also a number of scientific reports and observations indicating that runaway warming might be avoided if we can increase sequestration of excess atmospheric carbon soon enough.
by Sutherland, et al., 26/01/2020 in Paleooceanography and Paleoclimatology
Global climate is likely to get warmer, and we want to know what will happen to marine life. We can study ancient warm periods to better predict the future. The ocean is a global carbon sink, because some organisms form shells by combining calcium with carbon dioxide dissolved in seawater. Once dead, their calcium carbonate shells sink to the seabed. Over millions of years, the southwest Pacific accumulated huge deposits. We used geophysical surveying and drilling to measure this history of deposition, which is a proxy for ancient biological productivity (how much marine life existed). A warm period 18–14 million years ago had high atmospheric carbon dioxide (2–4 times preindustrial levels) and slightly lower ocean productivity. In contrast, 8–4 million years ago, atmospheric carbon dioxide was similar to predicted 21st century levels and productivity was much higher: more than double recent values. Rates of calcium carbonate deposition in the past do not correlate with ocean acidity or atmospheric carbon dioxide; but they were mostly higher than today. Hence, long-term biological productivity and carbon sequestration in the southwest Pacific might increase in future, but computer models that fit our observations are needed to test this idea.

Sequestration of excess atmospheric carbon under the ocean is one of the very few technologies I have seen that plausibly scales up enough to cleanse Earth’s entire atmosphere. Some further evidence supporting this conclusion is discussed and linked here.
Stopping anthropogenic carbon emissions probably will not be enough to stop the continually increase in the rate of global warming because of the natural positive feedbacks already triggered. This has led to substantial work to find ways to capture/’draw-down’ atmospheric CO₂ for safe sequestration underground. Over the last year or so there has been a considerable buzz in the clean-tech industry to engineer and construct technological solutions under the name of ‘direct air capture’ for doing this. These are physical/chemical devices looking a lot like air-conditioning units, but a lot more complicated in the way they work.
Wearing the hat from the near life-long physics and engineering thread in my diverse background, I have to say that despite all the hype, the idea that this type of technology could be scaled up to have any significant impact on the planetary amount of atmospheric CO₂ has to be pure bulldust and fairy-floss from the fossil fuel industry. The ABC article where I found this illustration makes it clear, “The greatest challenge … is processing enough air to capture a significant amount of CO2, given the gas makes up just 0.04 per cent of the air we breathe.” Physically, it takes a lot of energy expensive ‘work’ to gather widely separated gas molecules and compress them into a small space where they can be packaged and stored. No matter how the compression is achieved, according to the universal and fundamental physical Second Law of Thermodynamics, this energy cost cannot be avoided. This is before considering the additional costs of mining, refining, or otherwise gathering and processing the materials required to build the technology, assembling the devices, and all the related transport and logistics of distributing them, processing the resulting compressed carbon into a sequesterable form and the placing it in some form of safe long-term storage. As implied in the ABC article, a lot of people will make loads of money that will be far more needed elsewhere, to implement this absurdly costly technology to make a microscopic contribution (assuming there is actually any net benefit at all) to solving the global problem.
Other examples of the hype I have discussed in my Facebook account include:
The biological and evolutionary thread in my life that began even before I learned to read. Wearing this hat, I can explain the absolute difference between the necessarily piece-rate and energy intensive processes required to produce engineered products, versus the intrinsic processes living systems use to reproduce and multiply themselves. They do this without any need for external instruction by self-harvesting the resources and energy they need from their surroundings. As such, living things also have the intrinsic capacity to adapt and evolve at least to some degree to meet changing aspects in their environments.
Plants (i.e., all types of photosynthesizing organisms) use energy from photons of light to capture CO₂ from their environments and combine this with water (H₂O) to produce the sugars that provide the starting point for synthesizing all of the other carbon-based organic molecules constructing the organism. Ultimately, all of this carbon is drawn down from the atmosphere (perhaps by way of first being dissolved in water). Thus, to live, grow, reproduce and multiply, plants MUST capture and hold onto carbon atoms for as long as they live. How and where they die determines how long this organic carbon remains sequestered away from the atmosphere.
The featured image heading up this post shows an equal area map of the extent of the oceans compared to land masses. Oceans cover around 70% of the total surface area of the globe. Land occupies the other 30%, but not all of this is remotely arable (e.g., the whole of Antarctica and many desert areas). The map is based on a “chlorophyll-based” model that estimates net primary production from chlorophyll using a temperature-dependent description of chlorophyll-specific photosynthetic efficiency. Net primary production is a function of chlorophyll, available light, and photosynthetic efficiency. The dark blue areas of the oceans away from the land are ‘ocean deserts’ where there is essentially no photosynthesis because there is an almost total absence of particular micronutrients phytoplankton need for building their photosynthetic apparatus.
I am certainly not the only person to have seen the potential importance of using the oceans as the major carbon sink for excess atmospheric CO₂. Committees of the US National Academies of Science, Engineering, and Medicine have published several reviews of potential carbon capture and sequestration technologies meriting funding for further research and development. The latest of these focuses specially on various kinds of ocean sequestraton (National Academies of Sciences, Engineering, and Medicine 2021. A Research Strategy for Ocean-based Carbon Dioxide Removal and Sequestration. Washington, DC: The National Academies Press.
).
This report builds heavily on previous National Academies studies, in particular the rationale and framing for research on carbon dioxide removal provided from the 2015 report on Climate Intervention: Carbon Dioxide Removal [“CDR”] and Reliable Sequestration. The ocean CDR report here also adds to the more terrestrial focus of the 2019 report on “Negative Emissions Technologies and Reliable Sequestration: A Research Agenda.”
To me, it is the areas of marine deserts (~ half the surface of the world’s oceans) that are the most interesting, because this is where the potential should be greatest to use fertilization and farming to establish and control ecosystems optimized to capture and sequester carbon while causing minimal disturbance to already established ecosystems in more fertile areas of the world’s oceans. Chapter 3, Nutrient Fertilization in the National Academy’s review covers many general issues relating to this approach. There are also a number of recent scientific reports and observations that are relevant:
Collectively, together with many others I have seen, these references provide more than enough evidence to indicate that we should be able to seed and fertilize phytoplankton blooms over large areas of ocean desert to begin fixing globally significant amounts of atmospheric carbon into biomass. What remains to be worked out is how to optimize the growth and ‘packaging’ of this biomass carbon into relatively inert forms that will drop down into the abyssal depths to be incorporated in the bottom sediment.
This is the ‘farming’ aspect of the process involving the selection and seeding of appropriate phytoplankton species, and the selection, seeding, and husbanding of appropriate ‘consumer’ species to harvest and package a large proportion of the carbon in the phytoplankton as feces (i.e., ‘droppings’) or in the consumers own dead bodies that are dense enough to fall to the bottom out of the photic zone where the phytoplankton photosynthesize. Consumers may be shelled zooplankton, other invertebrates with dense carbonaceous components, or various kinds of fish, mammals or birds that can be counted on to take a significant mass of carbon to the bottom of the ocean when they die.
In principle, it should be possible to scale up such processes rapidly enough to begin drawing down carbon from the atmosphere before runaway warming has passed the point beyond which the positive feedbacks have become unstoppable. Once we have good recipes, given the propensity of biological systems to MULTIPLY autonomously, the processes should be rapidly expandable to the planetary scale. However, there are all kinds of presently unqualified risks and benefits to be faced from putting such activities into practice that need to be studied and qualified before implementation begins. Given the hints and evidence in the scientific literature, there should be hundreds and thousands of research studies working out the uncertainties to the point where large-scale pilot projects can be put to work as required to begin implementing global solutions.
Unfortunately, I am unaware that anything remotely close to the required volume of research has even been contemplated, let alone set to work…..
Why?????????
In my opinion the LNP COALition and the collection of egocentric clowns and knaves also owned by the same puppet masters in the fossil fuel and other despoiling industries have made their denial of climate science and support of their puppet masters unambiguously loud and clear. There seems to be no mistaking their intent to go on doing this until the final collapse of society under the rising impacts of the climate emergency.
If humanity is to survive on Earth much beyond the 21st Century we Australians and citizens of other governments around the world must remove the special interest puppets from their governments and replace these greedy clowns and knaves with clear-headed people who are committed to put fighting the climate emergency at the top of their to-do lists when elected.
In Australia, Vote Climate One was formed by a team of volunteers to provide citizens in every Federal electorate with the information and knowledge they need to make wise decisions when filling out their ballot papers in the next election.

Living things and soils store vast amounts of organic carbon. If this is lost to the atmosphere by wildfire, land clearing, or other disturbances it is not easily recovered
by Govind Bhutata 13/02/2022 Carbon Streaming Corporation in Visual Capitalist
The Earth is home to some natural ecosystems that function as carbon vaults, storing massive amounts of carbon. Researchers developed the concept of “irrecoverable carbon” to identify areas on the basis of three criteria relevant for conservation:
● Manageability: How they can be influenced by direct and local human actions
● Vulnerability: The magnitude of carbon lost upon disturbance
● Recoverability: The recoverability of carbon stocks following loss
Applying the three criteria across all ecosystems reveals that some places contain carbon that humans can manage, and if lost, could not be recovered by 2050, when the world needs to reach net-zero to avoid the catastrophic effects of climate change.
The above graphic sponsored by Carbon Streaming Corporation charts global irrecoverable carbon by land area, highlighting important ecosystems of stored carbon.

US Federal courts consider this vexing question: how much do greenhouse gas emissions cost society and who should pay this cost?
Jim Krane & Mark Finley, 13/02/2022 in The Conversation
What is the ‘social cost of carbon’? 2 energy experts explain after court ruling blocks Biden’s changes: When an electric company runs a coal- or natural gas-fired power plant, the greenhouse gases it releases cause harm – but the company isn’t paying for the damage. Instead, the costs show up in the billions of tax dollars spent each year to deal with the effects of climate change, such as fighting wildfires and protecting communities from floods, and in rising insurance costs. This damage is what economists call a “negative externality.” It is a cost to society, including to future generations, that is not covered by the price people pay for fossil fuels and other activities that emit greenhouse gases, like agriculture.
VC1 News Editor’s comment: Australians need to think about this in the run-up to our election. The costs to human society from human triggered global warming are already reaching catastrophic levels. If we cannot stop and reverse the warming process, near-term human extinction is likely. The social cost of this would be literally infinite (any costs divided by zero humans left is infinite). In other words, if we wish for our families to survive into the future, we need to spend whatever it takes to stop the warming. This won’t be helped by a present puppet government that continually denies and downplays the reality and often works to block any effective action against the carbon emissions of its puppet masters. Use Vote Climate One’s Traffic Light Voting System to replace them with people who will put climate action at the top of their to-do list if elected.
The European Space Agency presents some of its satellite-based research programs on ice melting and rising sea levels..
by Space for Our Climate 10/02/2022 — European Space Agency
New research sums up sea-level rise: Sea-level rise is arguably one of the most serious consequences of the climate crisis. While using satellite data to monitor how the height of the sea is changing provides critical evidence for decision-making, satellites are also essential to measuring the individual components, such as seawater temperature and glacier melt, that contribute to the overall rise. Confidence in the accuracy of these separate measures is key. ESA-funded research now confirms that the figures match up.
Several major legal actions to be taken to court this year hope to bring Australian governments & special interests to account for climate failures
by Kieran Pender 12/02/2022 in The Guardian
The environmental activists bringing the climate crisis to the courtroom: There’s a growing trend of climate litigation around the world. Here’s a look at the Australian cases likely to make headlines this year
At least since the 1800s, world sea levels have been rising gradually but at a slowly accelerating rate. Since in the last 140 years it has risen around 17 cm, with around 6 cm of that in the 20 years between 2000 and 2020. And this is only a small part of the hugely complex planetary climate system that has an inherently unpredictable capacity to produce abrupt and catastrophically large changes in climate conditions.
The rising sea-level has two sources: runoff from the land (mostly glacial melt water) and thermal expansion of the ocean itself due to warming from excess solar energy accumulating from the global warming process.
The melt water in the rising sea-level comes from two primary sources, melting glaciers and ice cap on Greenland that has increased 6-fold over the last couple of decades; and melting glaciers and ice cap on Antarctica which has more than doubled over the same time. This is measured by the loss of mass variable – representing the weight of the water that has been added to the oceans.
As described in the feature article below, the melting rate of a glacier is determined by its speed as it is creeping/sliding down the continental slope into the ocean. This in turn is determined by a complex set of interacting factors, e.g., temperature, angle of slope, width and roughness of the bed, how much meltwater is in the bed to lubricate/float the ice, where and how the ice may crack and crumble, how many bends there are in the valley, ocean conditions at the foot, whether and to what extent warm and salty (salt lowers the melting temperature of ice) ocean water penetrates into the glacier bed under its foot, thickness and extent of the floating ice shelf at the glacier’s foot and so on. Simply stated, melt rates are inherently unpredictable. However, one thing we can be sure of is that the melt rate will speed up as ambient temperatures increase the rate of ice melting, and rain replaces snow as the main form of precipitation.
The geological record provides good evidence that episodes of abrupt ice melting can cause raise sea-levels a lot faster than they are now, perhaps even showing large changes in rate over a few decades.
There may well be enough ice in the West Antarctic Ice Sheet — especially if combined with an equally rapid melting of the Greenland Ice Sheet to support an equivalent amount of melting to the Meltwater Pulse 1A. It is notable that the land surface underlying very large areas of both West Antarctica and Greenland are below sea level – giving ample opportunities for warm ocean water to help speed the melting and collapse of the ice sheets.
Why Melting Ice in Antarctica is Making Waves: Scientists recently discovered that the Thwaites Ice Shelf, a floating ice shelf that supports the Florida-sized Thwaites Glacier, could collapse in as little as five years because of global warming.
Climate Reality Project, 28/01/2022
This past December, the massive Thwaites Glacier in Western Antarctica made headlines for all the wrong reasons. Specifically, because new research revealed that the ice shelf preventing it from sliding into the ocean and drastically raising sea levels could collapse well within the next decade.
This Florida-sized glacier had already worried experts for years, going as far as to regularly be called the “Doomsday Glacier”. And yet, this update from the scientific community was still groundbreaking.
It’s news that the world — particularly low-lying island and coastal communities — should understand and act on. So, what exactly is Thwaites Glacier, what does the latest research about it say, and what consequences could come from its decline?
FIRST THINGS FIRST, WHAT IS THWAITES GLACIER?
Thwaites Glacier is a massive body of dense ice located in Western Antarctica. Measuring about 80 miles (120 km) across, it’s the widest glacier on Earth.

The glacier has an ice shelf — a permanent piece of floating ice connected to it — that branches out into the Amundsen Sea. Now, understanding what exactly an ice shelf does is crucial.

As long as the world continues to warm and large amounts of snow and ice remain lying on the land, sea levels will continue to rise. The risk of an abrupt sea-level rise is real. The human and economic costs of such an event would be catastrophic if it happens. It therefore makes very good sense that mitigation works should begin soon with planning in place at federal, state and local levels to accelerate the work if we have any clear early warning signs that abrupt melting is actually beginning.
It is also clear that our present LNP COALition governments deeply deny the risks Australia faces from global warming and the climate emergency, and should be replaced with rational people who put action on the climate emergency at the top of their to do lists if they should be elected to Parliament.
Also, from the official transcript dated 20/12/2019 from the PM’s own office, Scotty made it abundantly clear to John Stanley on 2GB Radio that HE doesn’t fight fires… “But I know Australians understand… that, you know, I don’t hold a hose, mate, and I don’t sit in a control room. That’s the brave people who do that are doing that job. But I know that Australians would want me back at this time out of these fatalities. So I’ll happily come back [from his secret holiday in Hawaii] and do that.”
Sixteen year-old Greta tells us and everyone at the 2019 World Economic Forum in Davos how we and our governments should actually respond to the climate emergency:
