TECHNICAL TRENDS (… REFLECTING ECONOMIC BOUNDARIES)

Bieringen, Germany Energy Crops

Mid to long term lower feed-in tariffs Rising „fuel‚ costs for maize etc Political debate using food for energy production Increased use of wastes

(cap on maize % in Germany and new Italian FiT) Flexible plants for various substrate rather than bonus optimized plants

(dependency on mono-substrates over plant lifetime)

Power distribution & peak management Energy production in biogas plants independent from out of control

factors wind/sun Biogas plants operation matching „grid demand‚ vs. high uptime to

ensure profitability Gas to Grid (using gas grid for storage) …larger plants > 2 MW (Triton)

UTS TRITON ® Preferred design for large plants (> 1 MW) Ring-in-ring arrangement of tanks Outer ring: high rate reactor Inner ring: post-reactor Concrete cover or gas membrane/storage Capacity: 1.8 – 2 MW/system vs. 0.8-1.0 MW Short piping length Low energy losses (5-10% vs. 20-30% therm) Compact construction (-30% footprint) Clean and straight forward plant design

rather than tank/reactor farms Low peristaltic energy consumption due to optimized circular plug flow

(< 7%, less dissipation) Circular and directed flow

Overcoming Substrate Management Challenges

Mantova, Italy Energy Crop & Slaughterhouse Waste

DOS & DON‘TS OVERCOMING FEEDSTOCK MANAGEMENT CHALLENGES

DOS DON‘TS

Flexible plant design for various substrates (mixing, pre-mixing tanks, volumen)

Recirculation of digestate Long term contracts or partial ownership of land Screening/batch tests Contaminants check Secure => 80% mid to long term supply for base

load Biological healthy substrate mix

Spot substrate market: caution! No quality check of input material Mono-substrates: caution: nutrient management

SUMMARY Trend to larger plants with increase use of various organic wastes (250-500 kW 1 MW and above)

Flexible plants including power on demand production of electricity or gas to grid

Technology evolution from „farm‚-style plants towards industrial style power plants Efficient & reliable design Higher technical advancements (equipment, PLC/Scada) Safety regulations (maintenance!) Professional and safe operation
