Algae-to-methane (A2M) has potential as an efficient and practical renewable energy strategy
• Algal biomass: minimal land & water usage• Methane: efficiently stored & energy on demand

A2M Research Aims
1. Experimental – Develop closed system with 100% nutrient recycling– Maximize methane production
2. Modeling – Develop accurate description of system– Predict system performance to achieve experimental
objectives
A2M Design
Temperature: 25 °C
