OBVIOUS CHP ≠ OBVIOUS
To keep all on board and happy… E 1-3
1 …Combining Heat & Power is obvious… E 4-8
2 …hence CHP plays major reduction role. E 9-10
3 EU tries, but fails to grow CHP… E 11-13
4 …as Separating Heat and Power pays E 14-19

..Combining Heat and Power is Obvious…
• Never use (fossil/RES) fuels for heating/power only
• Always cogenerate power/heat/cool/motion
• Stimulate heat/steam generation to co-produce power.
• (Re) Locate power generation near heat demand
• If possible maximize cascade and reuse of heat
• Integrate many small heat users by district heating networks, optimize scale/location of conversion
> Improves energy conversion efficiency and quality
> Saves fuel, emission, grids vs. separate generation
> Integrates well with RES and other saving options
…with different (Obvious) CHP levels per plant

Market reforms drove/drive CHP beyond the
obvious share %
Non-Obvious CHP: Reformed markets: Location/participation
stimuli; CHP for grid: bottom CO2 prices, valuable certificates,
Investment aid, exploitation support; Heat planning, DH; Ind
CHP; Cascading; Tax incentives; efficiency standards; etc.
Obvious CHP: Markets as is: Auto generation; Incidental DH
4. Beyond obvious CHP decentralises

Conflicting worldviews
• Physical/Rational
• Laws of nature
• Engineering / STEM
• Integral energy system
• Collective/long term
• Societal interest/offer
• Good Government
• Unite and Solve
• CHP! hi level principle
• Metaphysical/Emotional
• Laws of men
• Economics / Arts
• Power only/Heat only/..only
• Individual/short term
• Self interest/greed
• Populism Politics
• Divide and Rule
• CHP? Does not fit my box
Lessons from Holland
• Explain physical, integrated energy system view
• Push Energy Policy Politically– EED, Internal Energy Market, ETS, Market restructuring,…
– Provide investors security
• Improve energy economics– Market based: price emissions, networks, security…..
– Regulated: standards; cap, tax, min pricing, ……
• Execute non-market based energy policies
• Balance worldviews– Find the Middle
– Merge STEM and Arts to STEAM
Mind you! We only have One
WE LOVE LIVING ON THIS EARTH
WE ARE PASSIONATE ABOUT HEATING,
POWERING, COOLING IT,
AS EFFICIENT AS POSSIBLE
TOGETHER
