Back in March 2021, I wrote a study called Texas: Deregulated Electricity Hurts Its Customers. (https://labouraffairsmagazine.files.wordpress.com/2021/03/problem-045-texas-and-eugenics.pdf). This was mostly about the immediate failures. I’d accumulated a lot of notes about wider issues, but these had got too big for the magazine.
I promised a Part 2, and this should appear shortly. But this in turn was too small for a mass of notes on matters I found interesting. So rather than waste the earlier work, I show them here as a web page. Mostly as raw facts that you can make what you like of, but sometimes with comments.

“The geoengineering we talk about in the context of climate change falls into two very different categories: carbon geoengineering and solar geoengineering.

It is when you take carbon out of the atmosphere and store it underground or try to convert it into something else we can use. But it’s expensive, complicated and slow.
“Solar engineering is cheap and fast, but it doesn’t do anything to address the causes of climate change. As opposed to reducing greenhouse gas emissions, the idea is to change the energy balance by reflecting sunlight back into space.

“Fusion processes require fuel and a confined environment with sufficient temperature, pressure, and confinement time to create a plasma in which fusion can occur. The combination of these figures that results in a power-producing system is known as the Lawson criterion. In stars, the most common fuel is hydrogen, and gravity provides extremely long confinement times that reach the conditions needed for fusion energy production. Proposed fusion reactors generally use hydrogen isotopes such as deuterium and tritium (and especially a mixture of the two), which react more easily than hydrogen to allow them to reach the Lawson criterion requirements with less extreme conditions. Most designs aim to heat their fuel to tens of millions of degrees, which presents a major challenge in producing a successful design…
“By firing particle beams at targets, many fusion reactions have been tested, while the fuels considered for power have all been light elements like the isotopes of hydrogen—protium, deuterium, and tritium. The deuterium and helium-3 reaction requires helium-3, an isotope of helium so scarce on Earth that it would have to be mined extraterrestrially or produced by other nuclear reactions. Finally, researchers hope to perform the protium and boron-11 reaction, because it does not directly produce neutrons, though side reactions can.”. https://en.wikipedia.org/wiki/Fusion_power#Fuels

“Ammonia has recently emerged as a liquid storage and transport medium that has shown promising stability for long-distance hydrogen transport… Liquefied ammonia (NH3) can store 50% more hydrogen than liquid hydrogen. When ammonia is decomposed at high temperatures, only hydrogen and nitrogen gases are produced, with minimal carbon dioxide emissions. Because over 200 million tons of ammonia is currently produced annually for industrial use around the globe, the infrastructure for its mass storage and long-distance transport already exists and can simply be re-purposed for hydrogen transport…
“The need for large amounts of heat has been a pressing issue thwarting the widespread adoption of ammonia for use in hydrogen transport and storage, however. The decomposition reaction through which hydrogen is extracted from ammonia can only proceed at high temperatures which requires high energy input. A catalyst in the form of a solid powder can be added during the decomposition reaction to lower the reaction temperature; however, existing ruthenium-metal-based catalysts are very expensive and have low stability, thus requiring regular replacement.”. https://phys.org/news/2021-04-ammonia-decomposition-hydrogen-economy-efficiency.html

“Safe, lower-cost storage tech could find footholds in data centers, telecoms, and home and grid storage…
“Researchers have been promising to make sodium batteries viable for years. The technology might finally be catching up to its promise, with a couple companies now starting commercial deliveries…
“From a pure performance point-of-view, sodium-ion batteries are not attractive for portable electronics or electric vehicles… Lithium-ion batteries boast a higher energy density than sodium-ions, which means a compact lithium-ion will have a longer run time between charges. So far, sodium-ions have demonstrated about half the energy density of lithium…
“But sodium-ion batteries could give lithium-ions a run for their money in stationary applications like renewable energy storage for homes and the grid or backup power for data centers, where cost is more important than size and energy density. Based on currently available information, Abraham projects the cost of sodium-ion batteries to be about 10–20 percent less than lithium-ion.
“The biggest thing going for sodium batteries is their use of abundant, cheap, and benign materials. There is over one-thousand times more sodium than lithium in the Earth’s crust. It also costs less to extract and purify. Moreover, sodium metal oxide cathodes typically used in batteries—the anodes are carbon just like lithium-ion batteries—can be made from plentiful metals such as iron and manganese. Lithium-ion cathodes, by contrast, use cobalt, a metal with limited geological reserves and an iffy supply chain centered on a handful of countries. And other batteries such as lead-acid and nickel-cadmium contain toxic metals… The main attraction of sodium is sustainability…
“Sodium batteries are also more stable and safe than lithium-ion. They have a wider temperature range, are nonflammable, and there is no thermal runaway—which can cause lithium-ion batteries to catch fire—under any condition. https://spectrum.ieee.org/energywise/energy/batteries-storage/sodium-ion-batteries-poised-to-pick-off-large-scale-lithium-applications
Batteries With A Pinch of Salt
You could have a large battery in your own home, if you have space. It would make money by letting the central generator store electricity when it is surplus and tap it when short. And save you during power cuts.
But individual interest will never be enough. The needs would need to be pooled via the state and public regulations.
“The batteries that could make fossil fuels obsolete…
“Driven by steeply falling prices and technological progress that allows batteries to store ever-larger amounts of energy, grid-scale systems are seeing record growth. Many of the gains are spillovers from the auto industry’s race to build smaller, cheaper, and more powerful lithium-ion batteries for electric cars. In the US, state clean-energy mandates, along with tax incentives for storage systems that are paired with solar installations, are also playing an important role.
“The mass deployment of storage could overcome one of the biggest obstacles to renewable energy – its cycling between oversupply when the sun shines or the wind blows, and shortage when the Sun sets or the wind drops. By smoothing imbalances between supply and demand, proponents say, batteries can replace fossil fuel ‘peaker’ plants that kick in for a few hours a day when energy demands soar. As such, widespread energy storage could be key to expanding the reach of renewables and speeding the transition to a carbon-free power grid.”. https://www.bbc.com/future/article/20201217-renewable-power-the-worlds-largest-battery
“The Battery That Will Finally Unlock Massless Energy Storage…
“The main use case is for electric cars, where a literally massive amount of batteries take up a ton of room and don’t contribute to the actual structure of the car. In fact, these cars must be specially designed to carry the mass of the batteries.

“The UK government recently announced plans to fund companies that come forward with new technologies for large-scale energy storage. But their incentives to build grid storage technology at the appropriate scale are falling short.
“By the end of 2020, only about 600 megawatts of battery storage was running on the UK’s grid. As renewables like wind and solar increase to two or three times their current levels by 2030, energy surpluses and deficits will become more extreme. Large-scale storage could help balance the peaks and troughs, but companies aren’t being paid enough to justify the cost of building new storage in the first place…
“Several companies are offering to pay owners of energy storage devices (like home batteries) a fee to manage their devices over the internet – instructing the device to charge or discharge to the National Grid when necessary. Consumers can charge home batteries with electricity from the grid when it’s cheap (normally at night), and use this stored energy instead of buying more expensive electricity from the grid during the day. Millions of home storage devices could eventually charge and discharge according to algorithms in order to minimise costs to the consumer. But without strategies and tools to handle the effects of storage distributed across millions of buildings and electric vehicles, costs could mount on the companies managing the electricity infrastructure and grid operators.”. https://theconversation.com/energy-storage-technology-is-accelerating-but-grids-arent-ready-for-the-transition-156707

“Ultra-high voltage power lines are crucial to a greener future, but world leader China’s growing network has hit its fair share of snags…
“Expensive and difficult to build, UHV lines transmit energy at 800,000 volts and above, double the voltage of conventional high-voltage lines, allowing them to transmit up to five times more electricity at minimal energy loss along the way. They are seen as the answer to China’s energy imbalance: Whereas energy sources, including wind and sunshine, are mostly found inland, much of the country’s population lives toward the coast.”. https://www.sixthtone.com/news/1006932/untangling-the-crossed-wires-of-chinas-super-grid
