We will need lithium for a while as it appears the only viable EV battery technology for the next decade, when a lot of the transition will take place. There appears to be no shortage of the stuff in America and new extraction techniques should see the price of lithium carbonate drop. There are all kinds of other future possibilities and niches for the industry. Some of the American technologies I just posted about could be a direct threat to Chinese dominance in 5 years or so.

It should be limited to only necessary uses. The damage to environments costs more than the value it provides. Tap the brakes, slow down development using lithium batteries and pour funding into research and development of better alternatives.

There are new refining methods that are more cost effective and have a higher extraction rate. Like it or not they have fastened onto lithium battery technology, though I expect the traditional Li-ion battery to be extinct soon enough. There is nothing else close to industrial deployment and the extensive validation process these things must go through for EV use. It protects investors more than consumers IMO!

How to fix the climate by 2030?
Global leaders recently agreed to triple renewables capacity by 2030 while doubling energy efficiency. That'll solve all our problems, they tell us. And it will ensure the world gets to the apparent Holy Grail of 'Net Zero' by 2050. But is any of what they say really achievable?

The one difference is that lithium is recyclable, at least on human timescales.
Lithium occupies a corner of the periodic table and has a few extreme properties that are not easily copied by other chemistries.
Lithium (and for fixed installations where weight is not a big deal, sodium) are hard to beat for current battery tech.
The impossible? dream is dense, indefinitely cyclable electric storage without relying on chemistry.
If I can invite you to speculate, I’d like to hear what alternatives you think might be of interest in the next decades.

There is a recent report that shook up the investing world about quantumscape solid state battery validation tests. It looks like they can go a half a million km with less then 10% degradation, that sounds sustainable. They have had production issues in the past and missed goals and they are far from alone in the solid-state battery market. There are also new efficient and clean lithium extraction methods already developed and being industrialized with licensing agreements. Better living through chemistry...

In the middle of Canada and American Midwest block heaters for ICE cars are required for a few months of the winter and every apartment with parking and most workplaces have them and they operate at a bit over a kilowatt. I imagine battery heaters will replace block heaters in cold climate EVs. These guys claim it works at low enough temps from the article, which might help explain some of the hype around them.
However, "Energy can continue to move throughout the cell in extremely cold temperatures of -30 degrees Celsius — a temperature that renders other solid-state designs inoperable or seriously degrades wet lithium-ion batteries."

Looking into those Quatumscape batteries they seem to tick all the engineering boxes, wide temperature operation, enough energy density, inflammability and scalable? for mass production, and they have had their share of delays and bugs in production. However, the promise of the technology solves many problems for EVs and is worth the trouble, until another technology supplants them. I believe solid state silicon lithium batteries might be a thing and the energy density would be much higher. Betting on the battery market over the next decade will be risky to say the least and it is hard to pick winners over any length of time as the market shakes out.

This isn't going to help power passenger Electric Vehicles but provides some answers to the overall challenges confronting us as we proceed to a zero carbon future. Basically, the decision favors production of hydrogen using photovoltaics and geo energy while nuclear and fossil fuel sources are cut out of the picture. I think maybe they got this one right.

Why the hydrogen tax credit has become a lightning rod for controversy
So the debate over the 45V tax credit has become acutely focused on accounting for how the electricity hydrogen producers use from the grid is accounted for. If the energy used to make hydrogen is not actually clean, then hydrogen is not really a climate solution.
Some hydrogen industry stakeholders want the Treasury to implement strict electricity accounting standards to maximize the likelihood that the tax credits only go to hydrogen that is produced with the least possible amount of emissions.
Why the hydrogen tax credit has become a lightning rod for controversy
The Treasury still hasn't released guidance for how the IRA hydrogen tax credit will be implemented. Why energy and climate folks are anxiously awaiting word.

If solar is built out to the troughs in northern climates and not the peeks battery storage should be kept to a minimum, solar panels are much cheaper than batteries and should be for a long time. Then for about 9 months of the year we will have a super abundance of energy and can use it to make things like cement or green hydrogen. Catalytic electrolysis looks like how it will happen for now, but there have been recent discoveries of large natural hydrogen deposits in Europe, conveniently next to a major steel producing area. It is the same for western Australia which has vast iron ore deposits nearby and recent hydrogen discoveries, not to mention a great place for solar PV. This could help to jumpstart the green steel industry until other hydrogen production begins, hydrogen is difficult to transport and store and hydrogen embrittlement of metals is an issue too. A layer of graphene lining the inside of tanks and pipes can keep it from seeping through apparently.
Apparently, you can make cement using electricity too, but I dunno how efficient it is compared to traditional methods, Cement and steel making are big CO2 emitters. These folks developed a process and started a company.

This will need to put into the mix I would suspect, it varies in quality, from pure to some methane and CO2, it is not sustainable for the long term, but it might Jumpstart green steel and other hydrogen industrial users.This isn't going to help power passenger Electric Vehicles but provides some answers to the overall challenges confronting us as we proceed to a zero carbon future.

One way of making hydrogen is with a process called electrolysis, when electricity is passed through a substance to force a chemical change — in this case, splitting H2O into hydrogen and oxygen. To make hydrogen with electrolysis, hydrogen producers may use electricity from the larger energy grid. The electricity on the grid comes from many sources, some clean, like a solar farm, and some dirty, like from a coal-fired plant. On the electric grid, all that electricity gets mixed together.

Trying to keep it on topic and on policy and out of the climate change thread where concerns are raised about climate change and its impacts.

Love it when someone digs up old threads and see how fast things changed. Remember when EVs were the future and geothermics just experiments. Or when BYD was still a little known car brand, when governments and carmakers in the west were intimidated by their short success. Till BYD cars and buses did what anyone could have expected, fall apart too fast, almost as fast as a Tesla. Yeah the Germans showed once again what German engerineering is all about. And oh yes, hydrogen was still touted as a green miracle. Strange days.

You should see BYD on the roads of Europe soon, if the EU doesn't tariff them and with their energy squeeze, they seem reluctant to protect European car makers. VW might be in a competitive position with Quantumscape batteries soon though.

25 of the top 100 most spending EU lobby groups, back then, in 2023, were for lobbying for hydrogen:
But then it turned out producing all that required hydrogen required huge amounts of land, fresh water (especially in areas of the world there was little already), and electricity from renewable energy sources that could have been put to better use. Including wind parks along the coast of NL, for which Shell received enough subsidies that could have bought every household solar panels and heat pumps.
Europe practically had to recolonize Africa. And get the rest from repressive regimes and we basically started the same shit all over again. Though we replaced Russia's role with China. When they reached their goals it used 80% of the available renewable energy from solar and wind that was available when they started 7 years earlier, for creating hydrogen. On top of all that, in hindsight, in the first years after they completed the infrastructure there wasn't enough green hydrogen available to actually start switching to it and 99.9% of the hydrogen being produced was gray, created by some of the most well known in the image above. The fossil fuel using factories they built for that are still running and will be for decades.

FT projections I posted earlier show almost 100% EV sales by 2030 in the EU and non-EU countries of Europe. As for hydrogen there was a large deposit of natural hydrogen recently discovered in France and it is useful for making green steel.
