Apply Emerging Biomass Technologies to Recurring Needs

• Heat – Buildings – Processing

• Food Security – Greenhouse Heat – Soil fertility - Biochar for carbon smart

farming

• Power – <100 kWe - village and small community – >100 kWe – community and institutional

• Waste Disposal – Nonrecylable wood and paper – Wastewater sludge

• Fuel – Syngas to low cost diesel

FUEL: Why Not Make Oil in Alaska?

• Proton Power - hydrogen

• Hydrothermal Carbonization

– Urban and Municipal Waste

– PNNL Oil From Food waste

• Cool Planet – pyrolysis

Drop-in Gasoline, Diesel and

Biochar

Use Improved, New, and Emerging Technologies to Meet Needs

24 T R Miles Technical Consultants

The Way Ahead • Use demonstrated technologies to convert high ash

fuels to heat for energy and food production

• Build wood infrastructure through heating systems

• Use heating technologies that make electricity and biochar as co-products

• Use co-products (biochar) to grow food (e.g. greenhouse)

• Employ heat/power technologies that use wood and waste. e.g. gasification PHG

• Watch for Improved technologies - wait for commercial installations – Integrated Waste

– Liquid fuel

– Large power generation T R Miles Technical Consultants 25
