This video showcases a simple farm that creates infinite Minecraft fuel from smelting kelp and auto crafting it to kelp blocks. It requires the auto crafter recently introduced by Mojang and scheduled for Minecraft v1.21.
It contains a showcase using a kelp farm that can be built rapidly using flying machines. The farm as displayed here will generate between 500 (smaller version) and 1000 (larger version) dried kelp blocks per hour, allowing you to smelt 10000 to 20000 items in a supersmelter. The kelp farm has a footprint of about 30x65 (excluding the smelter setup and the clocks, which are spaced out to make the redstone easier to understand) and contains 1 (smaller) or 2 (larger) layers of kelp tanks, each 9 blocks high. You can easily multiply the efficiency by extending the length of the kelp tanks or by adding more modules on top.
The video also contains a tutorial for building the kelp tanks including the water streams.
The smelter setup should work in Bedrock as well, the kelp farm will work only in Java Minecraft because it requires flying machines.
