Energy Recycling – A Convenient Truth!

Thomas R. Casten

Past Chairman & CEOPrimary Energy, LLC

an inconvenient truth
An Inconvenient Truth
  • Al Gore has described global warming as an ‘Inconvenient Truth’ – a reality that we would rather not face
  • Present and coming policy changes mandate GHG (Greenhouse Gas) reductions
  • Conventional wisdom: restrictions will increase energy costs and penalize industry
more inconvenient truths
More ‘Inconvenient Truths”
  • Richard McCormack: US industrial production shrinking at alarming rate
  • Grid electricity cost is certain to rise due to CAIR, rebuilding US T&D system, and permanently higher fossil fuel prices
  • US fossil fuel addiction dictates foreign policy (and expensive wars), bloats balance of payments deficits, and exacerbates pollution control costs
a convenient truth energy recycling
‘A Convenient Truth’ Energy Recycling
  • US industrial waste energy could produce 20% of US electricity
    • Recycling creates significant new revenue streams for US manufacturers and reduces emissions
  • Power generation that recycles waste heat uses half of the fossil fuel of conventional generation
    • Recycling cuts power costs, reduces emissions
  • US industries single best hope to regain competitiveness: recycle waste energy
examining energy trends
Examining Energy Trends
  • New work by Robert U. Ayres examines relationship of energy, conversion to useful work, and GDP (Gross domestic product)
  • Raw energy use and GDP do not correlate, economists treat energy as simply a 4% factor in overall economy
  • Ayres finds changes in useful work explain over 50% of past century’s economic growth
economic growth driven by improving energy efficiency
Economic Growth Driven by Improving Energy Efficiency
  • Long trend of falling energy use per dollar of GDP, does not correlate with rising GDP
  • However, also long trend of increasing efficiency of converting exergy (potential energy) to useful work
  • Useful work per $ of GDP has been remarkably constant, explains over half of economic growth
  • Trends of energy efficiency have reversed, largely due to electric industry stagnation
exergy conversion to useful work by sector
Exergy Conversion to Useful work by Sector
  • Look at the % of exergy converted to useful work in low temperature heat, high temperature heat, lighting, and electricity
  • Electricity is by far the most efficient way to use energy, but
  • Efficiency has stagnated in electricity production
    • Stagnant power industry efficiency is key to many US problems, including industrial competitiveness, pollution, jobs, balance of payments, and global warming

defining recycled energy
Defining Recycled Energy
  • Recycled energy is useful energy derived from:
    • Exhaust heat from any industrial process or power generation
    • Industrial tail gas that would otherwise be flared, incinerated or vented,
    • Pressure drop in any gas

how can wva governance spur reduced energy costs ghg
How Can WVA Governance Spur Reduced Energy Costs & GHG
  • Modernize old rules that are now barriers to modern technology
  • Enable recycled energy projects to capture more of value they create
    • Reward local generation for avoiding T&D capital and line losses
    • Pay part of health and environmental savings to energy recycling facilities
more specific wva suggestions
More Specific WVA Suggestions
  • Provide open standard offer for power from energy recycling facilities
  • Provide limited loan guarantees for industrial energy recycling plants, valid only if waste energy supply ceases
  • Identify specific barriers to efficiency and enact new rules that serve the social purpose but do not block efficiency.
convenient truth energy recycling solves multiple problems
Convenient Truth:Energy Recycling Solves Multiple Problems
  • WVA can ‘mine’ industrial waste energy, create added revenue streams for industry
    • Recycle presently wasted energy streams to provide affordable, clean energy
  • Requires unconventional, innovative governance
    • Remove barriers to efficiency
    • Pay part of health savings to recycled energy facilities that create those savings
    • Pay T&D savings to energy recycling facilities
    • Permit energy recycling as pollution control device

Denmark Changed in Two Decades

  • Local pollution, global warming, and industrial competitiveness are all serious problems
  • The only ‘double dividend’ approach is energy recycling -- clean energy solutions that reduce costs and emissions
  • Our collective future depends on how fast governments remove barriers to efficiency and encourage clean energy
