  1. 1. COMBINED HEAT AND POWER (CHP) AS A VIABLE CLIMATE MITIGATION STRATEGY Lisa Martin, March 1, 2010 THESIS: CHP is currently a technically viable source of energy to be exploited using current technologies. CHP can play a significant role in reducing carbon emissions in the near term. MALS 4020
  2. 2. How does CHP Work? Before CHP Notice how most of the energy is vented off as waste heat. Including line loss, most of the energy potential is lost. Recycled Energy Development:
  3. 3. How does CHP Work? Using CHP By recycling waste heat through a boiler, chiller or direct thermal heat usage, most of the energy is used; less is wasted. Recycled Energy Development:
  4. 4. CHP has the potential to dramatically reduce energy consumption and lower GHG emissions. US currently has an energy efficiency rate of 13% Recapturing waste energy could boost efficiency to 87% Boosting industrial and energy sector efficiency could cut total energy demand by 23% by 2020 Aggressive CHP technology adoption could reduce GHG emissions by 100 million metric tons a year CHP technology could provide the USA with 20% of its stationary (non- vehicular) power needs. A review of the literature found
  5. 5. A number of barriers are slowing the spread of more widespread CHP use  Regulatory  Single greatest hurdle  Monopolistic & regulated utilities currently have economic disincentive to not promote efficiency  There are significant costs imposed by utilities on companies wishing to use CHP technology  Energy delivery systems must begin to reorient itself towards a more distributed energy system. Renewables also need a more distributed system; CHP adoption will help usher in needed regulatory and distribution requirements.  Initial Cost Barriers  Plant modifications will cost 520 billion dollars over 10 years.  Payback on initial investment in upgraded facilities will save 1.2 trillion dollars in energy costs.  Financing mechanism must be developed.
  6. 6. Research Approach  Power Generators and large industrial facilities do not have an extensive presence in the literature. Why? What do THEY have to say about CHP?  I would survey segments of these industries to assess reasons for lack of CHP adoption, and try to determine under what circumstances they would embrace these technologies?
  7. 7. THE CHEAPEST AND EASIEST ENERGY FOR THE USA TO EXPLOIT IS THAT WHICH WE ARE CURRENTLY THROWING AWAY. Add this to your list of climate mitigation strategies. It deserves serious policy attention.CHP
