The renewable energy changes and policy

Aquaculture done kind of like the biotech industry, power it with solar and away you go, farm other organisms for fish food too. A story from here in Nova Scotia that might be better than growing fish cells in a bioreactor. Grow cockroaches on garbage and feed them to fish, after processing and sterilization of course!

A better way to farm fish? | FT Food Revolution

Aquaculture, or fish farming, is the fastest growing form of food production in the world. Most fish farming is done in pens out at sea, but that comes with significant environmental problems. High-tech, land-based fish farms are still a niche part of the industry, but that may well change, as scrutiny about the way our seafood is raised intensifies.

Distributed generation never was in the utilities’ operating paradigm. To keep on with “business as usual” and service their shareholders, they have no real choice but to buy the extra household power at wholesale and sell it back at retail.

Only way this changes is if government intervenes and taxes the utilities into extinction. Or buys the grid from them.

ceterum censeo screw free-market “libertarians”.

we (meaning get around the corporations) can control it more and more. Right now today a person can produce power off grid and co-gen hydrogen to run a vehicle and/or a generator during non-sun days. This also has legs in the colder climates where a EV only gets ~50% efficiency from the manufacturer stated goal. It’s not really economical yet but my opinion is we will continue to see new and innovative ways to get off O&G.

twenty thousand (touches pinky to lip) dollars! for 3/4 of a cubic meter a day at normal pressure! I invoke your username.

Then you need a way to store the hydrogen (very high-pressure compressor, pressure vessels, regulators etc.) and to turn it back into electricity (fuel cells are big money and not a mature technology).

Yeah imo that is twenty years out before it makes sense for all but remotest locations.

If that process developed in Australia works out for small scale electrochemical ammonium production, a solar powered production cell could produce low volumes on ammonia, and it can be stored easily and accumulated over time to power emergency generators, ICE engines run fine on it.

I like that farming salmon on land idea, aquaculture done like biotech-controlled environment, no pests and the fish can be feed with insects and other things that shouldn't cost a lot of money and the whole operation can be solar powered. You can buy 50-pound bags of seawater concentrate powder (mostly salt) and mix it with fresh water and grow salmon anywhere, even close to an inland major market. If they grew their own insect feed of a few types, feed them on cheap waste products and solar energy was cheap, so should their costs with some automation to keep labor costs down. It would be a bio food factory close to markets running on bugs and salt water. Compete with that cell-based culture in a bioreactor!

Ammonia has some nonideal properties as a fuel.

One thing is certain: detecting leaks will be easy.

If yer gonna electrolyze using renewables to produce hydrogen, why not just use a different kind of cell to produce much more useful and easier to manage ammonia, all other things being equal or close. The ammonia cell seems as far along as most hydrogen electrolyzers and an electrochemically mediated process that uses lithium with water and air as feed stock sounds kinda neat.

They want to use it as ship fuel and one of those agricultural tanks holds a few hundred gallons of liquid and would run a backup generators for a long time.

We will see they appear to be testing container sized production units on farms in Australia now. The two scientists turned over management of the company to a pro and are still doing what they like, science.

I looked into their patented process and see few bugs to even scaling it much larger, it seems pretty solid with few bottlenecks and issues, and they are engineering things now to improve the efficiency.

I’ve made no bones about my faith in the holy trinity:

catalog numbers
retail prices
warranty terms.

I'm hopeful on this one, ammonia is a big one and the key to many other chemical processes, it is a big greenhouse emitter that requires high heat and lots of energy. This new process is no more energy efficient even though it has a faradic efficiency of 98% but it can run on renewables and make ammonia while the sun shines.

They have two papers, one in science and the other in nature and they have catalog numbers, it would be only retail to farmers and businesses, it is industrial equipment as for warranties, I imagine they offer them.
