What are your favorite RNG/Biofuel plays given the crazy diesel prices?

I’m certain the industry is getting significant tailwinds given the macro economics just curious if anyone has any interesting plays. My favorite is Opal Fuels

Background on CNG/RNG for transportation, 18-wheeler fleets are hard to electrify because of the downtime for charging, lack of power/torque, and lack of grid energy infrastructure, so many fleets are going to CNG/RNG. It’s the same fuel used in trash trucks, burns clean, half the price of diesel, comparable power… it’s a industry that is growing rapidly but I think the high diesel prices throw gas on the fire. What are your thoughts?
