NAU is looking into different on-campus renewable energy options to offset our carbon footprint. Because of NAU’s position in the largest Ponderosa Pine forest in North American, biomass is one option we are investigating. The Forest Service is working to restore 2.4 million acres of Northern Arizona forests that have been overgrown due to years of fire suppression. Learn more about the Four Forest Restoration Initiative (4FRI). Because 4FRI includes our local Coconino Forest as one that is in need of tree removal for forest health and community safety needs, NAU is in a perfect spot for using the removed biomass as fuel for a biomass plant on campus.
What is Biomass?
Types of material:
- energy crops
- crop residues
- sustainably-harvested wood and forest residues
- clean municipal and industrial wastes

Biomass Feasibility Study Accordion Closed
In 2014, NAU finished a biomass feasibility study. The study found three different scenarios the campus could implement to utilize biomass for heating and/or electricity:
• Project Scenario 1: Biomass to Heat – 20 MMBtu per hour
• Project Scenario 2: Biomass to Electricity – 2.5 MW behind the meter installation
• Project Scenario 3: Biomass to Electricity – 10 MW
Funding for the study came from six different departments. The Office of Research, Enrollment Management and Student Affairs, the Green Fund, Office of the Provost, and Finance and Administration contributed $10,000 and the Ecological Restoration Institute contributed $18,835.
