  • ISIE meeting was taking stock
  • SIEYP is looking forward, where IE is going next

Chris Kennedy is Professor, Civil Engineering at the U. of Toronto, and President of the International Society for Industrial Ecology

[Chris Kennedy]

Some work that is incomplete

  • Focused in infrastructure
  • Overlaps other parts of IE

Title part of idea from OECD

  • A new industrial field
  • Ecosystem that goes around industry

Start with Kalundborg, Denmark

  • Previous conference talks focused on oil refinery and electric power stations
  • But don’t want to focus there, because the future may not be around oil and electric

DI_20150711 034646 SIEYP ChrisKennedy GlobalEnergyUse

Work at different scales

  • Map of global energy system by Cullen and Allwood
  • Want final servies (e.g. transport), but we don’t like the old energy sources
  • Conversion devices will have to change
  • Leaders setting up from there

Stefan Pauliuk presentation:

  • Link infrastructure systems to their material use
  • Others working on global input-output models
  • Ming working on Infrastructure Ecology, could fit in here, too

Kennedy and Corfee-Morlot 2012 OECD work done as an economist, learning from industrial ecology over the year

  • From an economic perspective, how could we achieve a low carbon economy?
  • If we had the policies to promote energy efficiencies, then we no longer need to invest in the infrastructure that carries oil and natural gas
  • If decrease investment in oil and natural gas, the capital we free up needs to go into low carbon electricity generation, which makes vehicles low carbon as well
  • Result:  decrease demand for coal and oil, then don’t need to move coal and oil
  • Then can have some big infrastructure savings, particularly in countries that don’t already have them
  • Rail and ports are big infrastructure
  • Costing, enough to get working paper with OECD

DI_20150711 035227 SIEYP ChrisKennedy ChinasGreenInvestmentNeeds

Now working with OECD and government of China, about financing green investment in China

  • Working on Chapter 2, with colleague in Chinese university
  • (Numbers wrong, keep changing)
  • Chinese government really understands changing to an ecological civilization
  • Factor of 10 beyond U.S. superfund to clean up
  • Chart only shows to 2020, report will go beyond that
  • What’s missing is a trillion dollars for an industry treatment of waste coming out of solid, gaseous, liquid waste
  • This is just the investment in green stuff
  • Haven’t yet got data on savings in investment they won’t do

DI_20150711 035429 SIEYP ChrisKennedy ChinasWindPower MatthewsTan

Matthew and Tan 2014:  China’s Wind Power

  • Getting steeper and steeper

DI_20150711 035517 SIEYP ChrisKennedy ERI IRENA High Renewables

ERI & IRENA High Renewals Scenarios

  • Wind and solar means by 2050, oil and coal is reduced by 75%
  • Plan to do high renewalbles in China

DI_20150711 035612 SIEYP ChrisKennedy China2050HighRenewable

China’s primary energy consumption, ERI 2015

  • Coal peaks in 2020, if it already hasn’t
  • Is this possible thermodynamically, economically, socially?

DI_20150711 035636 SIEYP ChrisKennedy ChinasPrimaryEnergyConsumption

Typical day in China:  power from solar goes up during the day

Costs:  Wind power is now competitive with coal power in China

  • Coal costs would go up with infrastructure and environmental costs

Readapted Kennedy and Corfee-Morlot 2012, 2013 for China

  • Could poke holes in this
  • Link between coal and railway, in the context of a country that is still growing
  • China is impressive
  • UK to U.S. to China from industrial revolution scale goes up
  • China already has more high-speed rail than others

China has a Medium to Long-term Railway Network Plan, in the context  of China 2050 High Renewal Energy Penetration Scneario and Roadmap Study (2015)

  • 112,000 to 250,000km in 2050
  • But 50% of rail traffic is coal
  • What if coal demand goes down 75%

DI_20150711 035741 SIEYP ChrisKennedy HourlyDispatchOfNationalwidePowerGeneration

The amount of iron ore required to build 200km of dedicated freight ral lines is equivalent to 2000GW of onshore wind turbines

  • That’s close to the envisaged wind power for 2050
  • Want someone to redo the China railway plan, taking account of industrial ecology
  • Could then do this for India, for the U.S.

The go back to industrial symbiosis

DI_20150711 035851 SIEYP ChrisKennedy InteractionsBetweenInfrastructureSectors


Save steel by not building rails, but what about other energy storage technologies?

  • That’s for you to research
  • To be done
  • Fast high speed rail is sustainable, supported by electricity
  • Coal and steam engines are intensive

What about the U.S.?

  • As 4 to 5 years ago, 45% of rail tonnage is coal
  • It’s mature, shrinking rather than growing
