Renewable Energy Workshop, January 19, 2007 CHP Combined Heat and Power (Waste Heat Recycling) Dave Dewis Elliott Energy Systems

Renewable Energy Workshop, January 19, 2007 What to get from this presentation Understand what CHP is. Understand how it can help. Understand it is available Now. Not understand why CHP is not more widely utilized.

Renewable Energy Workshop, January 19, 2007 A well kept secret! In 1910 Fuel utilization was 65% Today, nearly 100yrs later, it is only 33%

Renewable Energy Workshop, January 19, 2007 Waste of Energy 67% of Central Power Station Input Energy is lost in the form of Heat.

Renewable Energy Workshop, January 19, 2007 Grid Efficiency As delivered to the customer electrical efficiency has stagnated for the last 40 years

Renewable Energy Workshop, January 19, 2007 CHP Comparison CHP Recycles the Waste Heat from Power Generation achieving efficiencies of over 80%.

Renewable Energy Workshop, January 19, 2007 CHP Deployment International Perspective

Renewable Energy Workshop, January 19, 2007 US CHP Goal 92GW by 2010 Recognizing the benefits of CHP. Both the EPA and DOE support the goal of 92GW by 2010

Renewable Energy Workshop, January 19, 2007 National Energy Policy CHP can achieve efficiencies of 80% or more.

Renewable Energy Workshop, January 19, 2007 Floridas Energy Plan Distributed Generation and CHP are cornerstones of Energy Efficiency in Floridas Energy Plan

Renewable Energy Workshop, January 19, 2007 CHP is Technology Neutral Turbine/MicroturbineIC Engine

Renewable Energy Workshop, January 19, 2007 Energy Intensities for Commercial/Institutional Buildings

Renewable Energy Workshop, January 19, 2007 Industrial CHP Applications

Renewable Energy Workshop, January 19, 2007 EES CHP Package Made in Florida RECUPERATOR HEAT EXCHANGER GAS BOOST COMPRESSOR OIL HEAT EXCHANGER WITH FAN ASSEMBLY POWER ELECTRONICS COOLING FAN ENGINE / ALTERNATOR ACOUSTIC SILENCER Dimensions: Height: 1981 mmNet Power Output: 100 kWe (ISO) Width: 838 mmThermal Output: 172 kW (net) Length: 3048 mmExhaust Temp. 288 deg-C (ISO) Dry Weight: 1860 kgFuel Input Flow: 0.63 m 3 /min

Renewable Energy Workshop, January 19, 2007 First microturbine to CE certify under severe Gas Appliance Directive rules. UL2200 Certified 3 configurations CE Marked CHP Monogen Hazardous Area / Offshore UL & CE Certified CHP System

Renewable Energy Workshop, January 19, 2007 Microturbine CHP Installations 15 - TA100 CHP units installed to provide hot water and supplemental electric power to the US Military base. 80 kW Power Generation Direct Exhaust Fired 40 USrT Absorption Chiller

Renewable Energy Workshop, January 19, 2007 The CHP Solution National Perspective Inadequate supply – Add up to 210 GWs of CHP. High energy costs – Cuts fuel by up to 2/3. Air pollution – Reduces emissions up to 2/3. Too few competitive suppliers – Many new ones. Major siting impacts – CHP plants small, near load. Long lead times – CHP in less than two years. Constrained transmission – CHP eases constraints. Power Security – CHP offers high levels of Security. Line losses of power – CHP suffers no line losses. So why arent we building CHP everywhere?

Renewable Energy Workshop, January 19, 2007 To Summarize CHP Can….. Reduce Fuel Consumption, easing our reliance on foreign fuel. Reduce Harmful Emissions of NOx and CO2. Increase Grid Security through Distributed Generation. So why arent we building CHP everywhere right now?

Renewable Energy Workshop, January 19, 2007 Breaking Down the Barriers The barriers to CHP are not economics or technology but are regulatory. Floridas Energy Plan lays the foundation of energy efficiency. CHP offers tomorrows energy efficiency dream today.
