And that is the million dollar question.
Continued R&D, extraction/manufacturing/incorporation/implementation of the product isn't going to be done in a day, more like years.
Do we have the time necessary for all that?
Just dealing with the Enviromental impact studies will take that long.

82 million
In the United States, the majority of housing units are single-family houses – about 82 million out of the total 129 million occupied units in 2021. These homes are mostly owner-occupied, but a small share is rented.Sep 4, 2023
U.S. single family homes - statistics & facts - Statista
Let's say you add in some commercial space for the equivalent of 100 million homes with say cheap local sodium battery storage. A typical Canadian family home uses roughly seven MWh per year, so under ideal circumstance, that 1 MW plant could power 1,200 homes. Now a future home would be powered by solar panels and storing energy in a cheap home battery bank, the plugged in EV and the hot water heater which can store as much energy as the battery, the excess going to the green new grid or drawing from it in times of need, home heating/AC is done with a heat pump.
Charging EVs too, a megawatt would serve say 1000 customers, but that's at a mere kWh per consumer on average and that is under ideal conditions. Let's say your 10kWh solar roof top produces just 5kWh for 10 hrs. a day on average, 50kWh/day. Now imagine how much less power the grid would have to generate and transport if 50 to 80% of the homes and commercial properties like offices, strip malls and stores in the country did this. Industrial parks are another area where there is plenty of roof top space and power usage. Solar panel prices continue to drop and there are now solar roofing shingle and tile products being sold now for domestic use. Cheaper solar and cheap sodium batteries for home battery banks will make such things happen. In ten years, the only ones buying solar panels might be grids and industry, solar shingles and tiles might be a better more economical choice.
A hundred million solar roof tops and battery banks could generate and store 50 gWh of power a day X 365= 18,250 gWh or over 18 tWh a year. Obviously, a quarter of this would be required to power our current needs, but more home heating and EVs will depend on the grid over the next decade or two and industry will rely on cheap power too. All residential power consumption amounted to 1.42 trillion kWh and even with EVs charging and with efficient heat pumps it is unlikely to go above 2 or 3 gWh.
Electricity consumption in the United States totaled 4,050 terawatt-hours in 2022, the highest value in the period under consideration. Figures represent energy end use, which is the sum of retail sales and direct use of electricity by the producing entity .Aug 31, 2023
Just a fraction of the single-family homes in America with on average 10kWh/hr of roof top PV generation and 20 or 30kWh of home storage could power the nation, EVs and all! Doubling the fraction producing 5kW/hr each could do it too. If you can store electricity and transport it, then producing enough of it with solar alone, even as far north as Canada, should not be an issue and there will be wind power too.

One can see the impact that going green will have on the grid, space heating and EV charging will cause some increases over the next 2 decades. Space heating and cooling needs should be mitigated somewhat by the increasing use of heat pumps. If it wasn't for LED lighting the energy usage would be off the charts! I could run 10 X 100-watt equivalent LED lights in my house, and each would only use 16 watts of power for a total of 160 watts.

No savings re cooling using air source heat pump but geo will cut energy a bit. Most existing older homes will require upgrade to electrical and insulation if using heat pumps (northern climates) to provide supplement strip heating and handle heat load. The cost of doing it was, in a lot of cases prohibitive. Payback was pushed beyond feasibility for many.One can see the impact that going green will have on the grid, space heating and EV charging will cause some increases over the next 2 decades.

Down east where we burn a lot of oil for heating and have moderate winters with temps often around zero heat pumps make sense, central Canada might be another issue. They might be an option for the coasts with the moderating effect of the sea, 90% of the year air units would do fine here.
Here's a thought, run the heat pump ground loop through the sewer pipe and recover a lot of heat, the snow on roads with large sewers under them melt faster in winter from all the heat coming out of houses with sewer water. It wouldn't do to freeze it though, but perhaps it and the thermal mass of the ground around it might do. Use air when the weather is mild and switch to the shitter when it gets cold!

If you are gonna generate solar and store it in a cheap home battery, the domestic hot water heater (designed to do so) can store as much thermal energy as the battery, so domestic hot water can be off the table for load. Heating and cooling the home needs to be efficient in terms of heating/cooling, but insulation and windows too. If you live in central Canada, you might have to supplement your heating and cooling for a portion of the year and on the coasts probably not at all. I do think we can use solar and cheap batteries to make most single-family house roof tops net producers of electricity for a smart green new grid, while topping up an EV at home, however in Canada with winter, short days and snow, it will be a challenge for many parts of the winter. We do have wind power and the grid will have energy storage though and if push comes to shove, we can fire up the natural gas turbo generators.

I wonder who is gonna try to commercialize these anodes, there is a big market for battery materials and components too, not just in making the final product. If production can be scaled someone probably will and it looks like it can be used in existing battery factories to improve future longevity and capacity. Lab work, but they are building just anodes, not complete batteries and it could end up going from the lab to the fab quickly.

The charging efficiency begins to matter. A 1% loss to heat means your battery pack is absorbing heat at a rate of 12 kW. If I did my math right, that’ll bring about three gallons of cool 20° water to a boil. Big batteries might need to incorporate a coolant loop!
Any idea how thick the conductors need to be to pass a kiloamp plus at like 800V?

I suppose ya could look it up or the formula to calculate it. The energy of say 100kWh in 6 minutes would require one Helluva charging cord and connector! The cable connecting the starter to the battery in an ICE car can carry a couple of hundred amps.

Shit, it will hook to the east, I should catch some of it, let's hope the lights don't go out on the weekend and it doesn't wreck the power grid from one end to the other. I hope it falls apart before it hits us, a cat 1 with big trees full of leaves is not good, the extra wind loading brings them down.

It's Official: International Agency Marks 'Beginning of The End' of The Fossil Fuel Era
For the first time, world demand for oil, gas and coal is forecast to peak this decade due to the "spectacular" growth of cleaner energy technologies and electric cars, the International Energy Agency's chief said Tuesday.
The IEA's annual World Energy Outlook, due out next month, will show that "the world is on the cusp of a historic turning point", executive director Fatih Birol wrote in a column in the Financial Times.
The shift will have implications for the battle against climate change as it will bring forward the peak in greenhouse gas emissions, Birol said.
"Fossil fuels will be with us for many years to come – but looking at our numbers, we may be witnessing the beginning of the end of the fossil fuel era," Birol said in separate comments released by the IEA.
Birol said the change is mostly driven by the "spectacular growth" of clean energy technologies and electric vehicles, along with structural changes in the Chinese economy and the fallout from the energy crisis.
Birol warned, however, that the projected declines in oil, gas and coal demand are "nowhere near steep enough to put the world on a path to limiting global warming" to 1.5 degrees Celsius – the preferred target under the Paris Agreement.
Meeting this goal "will require significantly stronger and faster policy action by governments", he added.
UN warning
The fate of fossil fuels will be at the heart of the debates at the UN's COP28 climate summit in Dubai, a major oil producer, between November 30 and December 12.
In a progress report on Friday, the United Nations warned that the world was "not on track" to meet the long-term goals of the Paris Agreement.
Global greenhouse gas emissions must peak by 2025 and drop sharply thereafter to keep the 1.5° C target in view, the report said.
Phasing out fossil fuels whose emissions cannot be captured or compensated is also required to achieve the goal of net-zero carbon emissions by 2050, the UN said.
The IEA already predicted in a report in June that a peak global oil demand was "in sight" before the end of the decade, but it is the first time that it makes such an assessment for coal and gas.
"Our latest projections show that the growth of electric vehicles around the world, especially in China, means oil demand is on course to peak before 2030," Birol said Tuesday.
After staying "stubbornly high" for the past decade, coal demand is set to peak "in the next few years", he said.
And the "Golden Age of Gas" – first called by the IEA in 2011 – "is now nearing an end", with demand set to fall in advanced economies later this decade, Birol added.
"This is the result of renewables increasingly outmatching gas for producing electricity, the rise of heat pumps and Europe's accelerated shift away from gas following Russia's invasion of Ukraine," he said.
Transition 'firmly advancing'
Simone Tagliapietra, a climate expert and senior fellow at the Bruegel think tank in Brussels, said that the IEA's new projections "illustrate that while still to slow, the global energy transition is firmly advancing".
"As technologies like wind and solar are now cost competitive, the transition moves from being policy-driven to being technology-driven," he said.
"This is a key feature, as it protects the process from political headwinds."
Analysts at Royal Bank of Canada said in a note that the IEA's new projections highlight the "success in pro-renewables legislation".
"Despite this, there is still scope for policymakers to do more to accelerate the energy transition and the phase-out of fossil fuels, with debates continuing across major economies in areas such as renewable returns and affordability," the RBC analysts said.

Looks like people might be holding out for better batteries and the factories are being built now, in 2 or 3 years you might get a much better EV for less money. Right now, in NA they are building EV versions of boats, like SUVs and half tons and these inefficient vehicles won't get much range, charge very fast, or work well in the cold with the current generation of Li-ion batteries. These are mostly for the upper end of the market and profit margins are high, they have yet to build a good cheap compact efficient EV that most people can afford because profit margins are low on such vehicles. Such small cars should get the largest rebates because they impose much less load on the grid and infrastructure, they can be easily charged from home overnight. Slow charging will greatly extend battery life as will topping up a nearly full battery, deep cycling and fast charging it, causes stress.

And below -20C it does not snow because it is too cold. Or at least the engineers from Toronto seemed to think about the prairies when they designed a helicopter pad (we could keep it ice free by heating the pad). Bet we could freeze a sewer pipe in winter, talk about being up shits creek in that scenario. We get people's water lines freeze on occasion, the price of keeping the roads clean I guess.
I will be getting a new furnace next year (current one, please last that long) and it will have an air heat pump rather than just being a furnace and AC. I think they have them working to -20, seem to recall them saying -30 is on the way.
