  1. Energy Efficiency & Sustainability Solutions for Industry – DOE Sponsored Programs at the University of Michigan Arvind Atreya Professor, Department of Mechanical Engineering Director, Michigan Industrial Energy Center University of Michigan, Ann Arbor 48109 Tel: (734) 647 4790 ; Cell: (734) 972 3542 aatreya@umich.edu

  2. Range of Programs at U of M Purpose: Increase energy efficiency, productivity, profitability, and reduce pollutants in manufacturing processes. An Integrated delivery of Service, Education & Research from UM. • Industrial Assessment Center (IAC) – DOE • Small & medium sized industries – usually simple implementable measures. • Michigan Industrial Energy Center (MIEC) – DOE • Larger industries – more sophisticated measures • Energy Managers Training – UM distance learning. • Renewable Energy & Energy Efficient Technology Demonstration – State of Michigan. • High payoff new technology demonstration. Best of all: IT IS FREE AND CONFIDENTIAL

  3. Why Industry – It is the largest energy using sector • 32% of total U.S. consumption ~ 32 Quads > transportation ~ 28% • 37% of U.S. natural gas demand • 29% of U.S. electricity demand • 30% of U.S. greenhouse gas emissions • Studies show that energy efficiency is the most cost-effective CO2 reduction option • Large opportunities for: • Energy reduction • Emissions reductions • Fuel flexibility • Green biofuels

  4. Facilities 8% Other4% Electro-chemical 2% Small 5% (MIEC training) ProcessCooling1% 112,398 Mid-Size Plants 37% Steam 35% Motor Systems 12% Combustion of fossil fuels. Either in boilers or furnaces. IAC & MIEC Process Heating 38% Manufacturing Energy Used by Plant Size and System Type (%) System Type: % Total Energy Use Plant Size: % Total Energy Use 4,014 Large Plants 58% MIEC & State of Michigan

  5. Industrial Assessment Centers (IACs) • Energy audit and industrial assessment • No cost to small/medium manufacturers • Conducted by university-based team of engineering faculty and students • Confidential report sent to plant within 60 days of the site visit • Usually simple implementable measures. • Average savings per assessment: $50,000/yr • 4 – 5 students trained and financially supported each year • Industries may require financial assistance in the form of rebates & low-interest loans – State and Utilities.

  6. Components of the IAC Assessment Pre-Assessment Analysis & Reporting Assessment Visit Follow Up • Duration: One Day • Meet with plant management team • Present details of pre-assessment analysis • Tour plant • Collect operating data • Conduct diagnostic testing • Discuss preliminary assessment findings with management • Prioritize potential recommendations for further analysis • Conduct follow up discussions with plant, 6-9 months following assessment visit • Identify implemented energy savings • Upload implementation data into the IAC database • Conduct engineering and financial analyses of priority recommendations • Develop first order estimates of implementation costs • Document results in “GOLD Standard” format assessment report • Upload report data into IAC database • Deliver report to plant within 60 days from plant visit • To be completed before assessment visit • Gather plant data including product type, annual sales levels, production levels, operating hours • Study processes and plant layout • Analyze utility billing data • Identify key energy systems • Develop assessment day strategy

  7. Michigan Industrial Energy Center (MIEC)  EPACT, EISA & MI-SB213

  8. Energy Opportunities in the Industrial Sector Efficient Operating and Maintenance Practices: High payback operating practices to enhance efficiency in manufacturing. – Help provided by IAC & MIEC through visits & training. Adoption of State-of-the-Art Technology: Improved energy efficiency through new available technology. – Implementation help from MIEC & State of MI. Fuel and Feedstock Substitution: Fuel flexibility to adapt to dynamic energy prices and supply issues – New Technology Implementation: MIEC, State of MI, & IAC. MIEC & IAC can also provide Renewable Fuel Technology Solutions: To improve global competitiveness & meet the Global Warming and Environmental Regulations. – Requires technology innovation and research.

  9. Biggest payback from new technologies

  10. Maximum It is important to note that the proposed system provides fuel savings due to both preheat and O2%. Fuel Savings – O2 enrichment + air preheat Example:
