It would be awesome if you could add a compatibility feature with Klonan's "KS Power" mod (https://mods.factorio.com/mod/KS_Power)
to allow us to use Ethanol as fuel in the Diesel Generator.

I did some googling, and Ethanol can be used in diesel engines.
However, it has a lower fuel efficiency/economy compared to diesel fuel, only containing about 67% of the energy per liter.

In KS Power, Diesel Fuel has a fuel value of 1.5 Megajoules per unit, therefore Ethanol should have a fuel value of 1 Megajoule to be accurate.

Additionally, burning pure Ethanol is much more clean compared to burning Diesel fuel, (up to ~100% less CO2)
but for game balance, it might be good to make it like 10% fuel pollution instead of 0%. (we can just say that there's some contaminants from the berries lol)

I know that in your modpack, Ethanol is primarily used as a catalyst in cracking oil, but I think this would add a fun secondary usage for it!

I like this idea. I have added fuel values for ethanol, works with KS Power, Gas Generator (https://mods.factorio.com/mod/gas-generator), Gas Boiler (https://mods.factorio.com/mod/gas-boiler), and potentially other mods which set a fuel value for vanilla fluids. I gave ethanol 50% efficiency with KS Power for balance. Also ~100% less C02 from burning doesn't make sense to me, I think that may refer to net emissions accounting for the C02 being absorbed as the corn (or berries) are growing which is then released as it is burned. The berry plants on the map absorb pollution like trees so this is roughly accounted for.

I also added fuel values to seed oil and puff gas when BM: Industry is installed.
