For the research portion, there are (unfortunately) lower impact journals like where the following paper -- about replacing aeronautical alloys with alumina-- is from:

For organoid intelligence, more hyped so you have higher impact, free journals

Japan has a lot of interesting not-quite-industrial family run high tech businesses. Solar pumped lasers I mentioned, but there's also crystal growing, small scale almost cottage level hightech paper and wood makers. Few reading materials though. Some of this "movement" will eventually diffuse to China, Korea and finally India.
These are about nearer term substitutes, a lot of them still involve industrial processes, but it is much easier to tweak industrial processes to turn them solarpunk than to replace entire classes of materials.
For the finance angle, I'm afraid I won't be able to direct you to any good free roadmap for Year 50 to Year 250, but for Year 0 to 50 I recommend studying how governments in the asia-pacific are funding decarbonization R&D, especially in SMEs. (Although we might be more interested in Africa or India?) Pay attention to IP law reform.
E.g. japanese gov report here (I was especially interested in the optoelectronics, for reasons of "demetallization", but Japan has small very localizable optics firms, think Thor but localized).

R & D expenditures for optoelectronic fusion technology that is expected to reduce energy consumption by up to 40 per cent in data centers. Optoelectronic fusion is a technology that fuses circuits that handle electrical signals and optical signals. Calculations have been performed with "binary numbers" by switching on and off of the electricity in conventional computers.Electricity however generates heat when it flows through circuits, and energy is used to generate heat that is not originally necessary, and when it generates heat, the resistance of the electric paths increases,leading to decreases in the calculation speeds. Therefore, research is underway to replace calculation using electricity with processing using light.Power saving and low latency are achieved by connecting internal circuits in computers with light without using electricity as much as possible. The aim is to gradually introduce light into computing chips or peripheral equipment in computers that have been processed by electricity.The aims are ﴾1﴿ to establish a technology that connects chips used for calculation and peripheral equipment with light in 2024, ﴾2﴿ to connect between chips with light in 2024 and ﴾3﴿ to practically realize a photoelectric fusion chip that calculates with light in the final stage in 2030. There are some estimation that the spread of optoelectronic fusion technology will save more than 40 per cent of energy by 2030 compared to the current state-of-the-art data centers.

used to be many small town companies in the US doing this, you can imagine, IF THERE WAS DEMAND from your cow rearing neighbours..
