5.  Abstract  : The Theory of Constraints, made famous by Eliyahu M. Goldratt in his book The Goal, says that “the throughput of any system is determined by one constraint (bottleneck).” Thus, to increase the efficiency of any system, one must focus on identifying that one constraint and improving it.   “An hour saved at a non-bottleneck [process] is a mirage.”

This talk focuses on addressing primary constraints in our energy supply chains with next generation stationary and mobile fuel cell systems (FCSs).  An energy supply chain constraint can be defined as a process that has the highest energy losses, greenhouse gas emissions, air pollution emissions, energy costs, lack of security of energy supply, or other negative impacts or costs.  For example, within the U.S. electricity supply chain, the greatest energy losses are not in the transmission and distribution of electricity, but rather at the point of electricity generation; approximately 20% of all U.S. primary energy consumption is lost as heat at power plants; approximately the same quantity of heat is regenerated at buildings for space and hot water heating.  As another example, some of the highest air pollution emissions in the electricity supply chain are seen at power plants under fast ramping conditions, a segment of the electricity market where the highest growth is expected.
This talk focuses on addressing primary energy supply chain constraints with future advanced FCSs.  For example, stationary combined heat and power (CHP) FCSs have the potential to displace the heat losses at power plants and the heat re-generated within buildings, each of which equate to about ~20% of total primary U.S. energy demand, at high electrical efficiencies (~60%) and overall efficiencies (~95%).  Insights are shared into the engineering design, economics, and environmental impacts of these advanced fuel cell and hydrogen energy concepts: CHP FCSs; combined cooling, heating and electric power (CCHP) FCSs; tri-generative FCSs for electricity, heat, and hydrogen production (H2-FCSs); automotive FCSs; and hydrogen storage.
Key results are discussed from detailed thermodynamics modeling and techno-economic-environmental impact modeling.  Important findings are also highlighted from independent analyses of measured data from deployed systems.
