Waste fuels struggle despite coal’s decline.

Fuel supply might be the biggest barrier to scaling-up biomass power generation, but it’s by no means the only problem. Utility projects to repower coal-fired plants face permitting challenges, ballooning technology costs and strained economics. Some owners are giving up the fight.
