Tests have been done and research conducted. Some agricultural businesses have installed biomass heating systems, but those businesses need heat all year long, not just over short periods, as in the grain sector. In our sector, the fall grain drying and conditioning period is extremely short. So there's no way we can get a good return on a massive investment in biomass-based equipment.
The situation's somewhat the same if you use electric energy as a heat source. The technologies we know and are using right now are obviously natural gas and propane, mainly use for different commercial reasons.
