Title: BTU Act of 2021
Policy area: Taxation

Summary:
Biomass Thermal Utilization Act of 2021 or the BTU Act of 2021
This bill expands the 30% energy tax credit to include open-loop biomass heating property and extends the residential energy efficient property tax credit for five years.
The bill defines open-loop biomass heating property as any property that uses open-loop biomass to produce thermal energy in the form of heat, hot water, hot air, or steam and is used for space heating, air conditioning, domestic hot water, or industrial process heat, but does not include any boiler or furnace unless they operate at thermal output efficiencies of at least 75% and are installed indoors.

                        heating property, including boilers or furnaces 
                        that operate at thermal output efficiencies of 
                        not less than 75 percent (measured by the lower 
                        heating value of the fuel at nominal output), 
                        that are installed indoors, and that provide 
                        thermal energy in the form of heat, hot water, 
                        or steam for space heating, air conditioning, 
                        domestic hot water, or industrial process 
                        heat,''.
