One potential use is co2 sequestration (if you sink it) as kelp grows way faster than trees (several feet in a day) It can also be a cheap livestock feed. And it can grow with very few input costs (no herbicide, fertilizer) all you need is an area of ocean, some ropes nets etc. And it will grow in winter. Theres a Canadian guy former fisherman who has been building a market for it as well. Often it can include mussels and oyster farms.

Theres a lot of other minerals that are useful. Theres a Ted talk on harvesting these.

Liquid ammonia has more hydrogen than liquid hydrogen, and has properties similiar to propane. Theres an existing infrastructure in naking it and transportation. There's 10,000miles of ammonia pipelines in the US (for fertlizer)

I know perfectly well what market share means. You can do a search yourself - "ev market share in Germany" and its less than 2%.

Again misleading, Germany 1.3% of cars are bev and 1.3 are plugins.

You put misleading info like 55% of market share making it seem as if evs are 55% of the fleet and its no such thing its less than 2% as anyone can simply check for themselves. A graph (esp in the less than 2% range) is not proof of anything. Higher production involves using limited and costly raw materials. Look at how much lithium cost increased in the past year. It has even more demand for grid batteries.
There is also the cost, evs dont really have a cost advantage over icev and there are still range issues (and infrastructure charging stations) and currently thanks to its past planning Germany has among the highest electricity prices in Europe per kwh (so much so that Siemens and other heavy industry have to have subsidized discounted electricity)
With an increased ev fleet, there needs to be more electricity generation to replace all the fossil fuels used and charging at night is not going to do it.
Also the used ev market is questionable due to battery degradation.
Im sure evs will continue to grow but it will take a lot longer and unlikely to be 100%. Tow trucks, heavy equipment will likely be still synthetic fuels.

Bevs in Germany are 1.3% of the fleet and plugin 1.3% as well in 2022.

Lithium prices up 900% last year.
Lots of work on new batteries all the time. But lithium ion has a multi decade headstart and development and production takes years. Any new battery will be 15 years before it is in significant production.

Norway is an outlier. Its 3million people and a country with the worlds largest sovereign wealth fund at over $1trillion
Currently there are 18million evs and 1.6billion vehicles worldwide, so its less than 2%
Also what is the worlds lithium supply (maybe 130million tonnes?) As you use it and other metals class 1 nickel, copper, chromium as demand grows so will the price. It takes 7 to 10 years to get a mine in production.
Also the Japanese are working on using ammonia for power plants and power marine shipping. There are no co2 emissions and (it can be green you can make it with renewables) and can carry more hydrogen than liquid hydrogen.

Reply to Italian startup Energy Dome claims its CO2 grid storage batteries are cheaper than lithium-ion, and need no rare minerals, being made from just off-the-shelf steel components, water & CO2. It's opening its first 200 MWh facility in Sardinia in 2023 by lughnasadh
I wonder how this compares to Highview Power from the UK which uses liquid air. And already has some working installations.

Reply to comment by Polymathy1 in My nans getting dementia, sort of sad sort of funny by mistermaster415
I found my mom would laugh if we all laughed when someone said something funny and she didnt even really hear it. There something positive and feel good about having a laugh with your family.
She definitely liked having music and I would have music playing when making dinner and though she no longer cooked I'd get her involved with chopping vegetables and she liked to help.
Sometimes she would take drama on tv for real and would say look what that awful person did etc..
So if we had the tv it might be mr Bean where could still really enjoy the simple humour or music on youtube.
We were lucky to have private caregivers come to her (and she livrd with my brother so she wasnt alone too much) and was able to live at home as long as she could.

Reply to comment by RedCascadian in Could offshore wind sites host edible seaweed farms? The Swedes think so by thorium43
Yes, in fact they can just grow it and sink it, and it grows very fast. It can actually be a good animal feed that is cheap (if you can transport it) and reduces the cow burps.

And the great thing about seaweed and shellfish farming is that there are very few inputs required as compared with land agriculture (ie fertilizer, weed killer, etc) and it grows all year round.
Cbc featured a Newfoundland fisherman who went from fishing to growing seaweed and oysters and mussels. He has been really good at promoting the industry.

Exactly, very few input costs, just ropes, nets no herbicides, fertlizer and you dont have to own land just get a licence for a bit of ocean. A small startup investment cost. Given the worsening drought in California and other parts of the US you dont have to worry about water.
