Energy use and emissions from industrial sector

Electrification and Decarbonization Solutions for Industry – Review of the Common Issues and Potential Solutions – SEA Workshop – April 5-7, 2022

2

  • 44% of industrial energy consumption is in the form of fuel1
  • accounts for 19% (w/o indirect emission from imported of heat or electricity) of global emission2
    • Feedstock: conditioning (e.g., calcination), energy carrier (e.g., SMR), carbon source (e.g., naphtha cracker)
      • Hard to decarbonize inherently without disruptive novel technologies
    • High-temperature (> 500 °C) heat: potentially most attractive target for electrification
    • Low/mid-temp heat: decarbonize via energy efficiency improvement and/or electrification

Decarbonizing chemicals manufacturing: SCALE and….

Electrification and Decarbonization Solutions for Industry – Review of the Common Issues and Potential Solutions – SEA Workshop – April 5-7, 2022

3

  • Chemical industry consumes 28% of industrial and 10% of global energy: mostly fossil-sourced3
    • use as carbon feedstock (58%) or to generate process energy (42%)
    • current use of electricity: ~ 22% (10 EJ or 2.8 PWh)
  • CCU: potential to decouple from fossil resources and reduce emission up to 3.5 Gt CO2/yr by 20303
    • will require 18.1 PWh of low-carbon electricity (55% of the projected global electricity production in 2030)!!!
  • Unique techno-economic challenges to decarbonize chemicals manufacturing sector
    • changing feedstock might require new process, e.g., SMR of NG for ammonia vs. water electrolyzer
    • adaptation and scale-up of alternative furnace (electric or hydrogen) for very high temperature (>1000 °C) heat: burner design, fuel mixing, safety consideration
    • any change in part of the highly integrated process chain have will require changes to other parts of the process
    • requires continuous supply of energy at scale: sudden interruption can cause havoc
    • huge size/scale and long life-time (40+ years) of facilities: require time- and capital-intensive retrofit
    • relatively low profit margin and global competition for low-cost production: little incentive to decarbonize

Direct electrification of heating in industrial sector

Electrification and Decarbonization Solutions for Industry – Review of the Common Issues and Potential Solutions – SEA Workshop – April 5-7, 2022

4

  • High/very-high efficiency, precise, faster response, stable, high-power density, greater depth of penetration
    • High TRL options: electric boiler, electric arc furnace, heat-pump (mid/low-T), microwave drying, mechanical vapor recompression, membrane separation
    • Low TRL developments: high-T heat pump, plasma kiln and furnace, plasma heating or direct electrical heating of ore, membrane separation for olefins, electro-catalytic synthesis,, electrowinning and direct hydrogen reduction, electro-magnetic heating (EMH) technologies (induction, radio, MW, IR, UV)

    • EMH technologies potentials:
      • new paradigm in high-efficiency catalytic processes: high temperature gradient in a relatively short distance (mm range)
      • high-penetration depth
      • precise heating

Indirect electrification using hydrogen: pay attention to efficiency!

Electrification and Decarbonization Solutions for Industry – Review of the Common Issues and Potential Solutions – SEA Workshop – April 5-7, 2022

5

  • Hydrogen produced using carbon-free electricity is used as natural gas substitute in thermal processes
  • ~40% loss of electric energy input to electrolyser to get H2 @ 700 bar!4
    • power generation using hydrogen as vector: requires scenario specific analysis to qualify

Electrification of industrial sector: demand & supply scenario

Electrification and Decarbonization Solutions for Industry – Review of the Common Issues and Potential Solutions – SEA Workshop – April 5-7, 2022

6

  • Share of electricity in industrial energy mix: 21%
    • complete electrification energy resources will require supplying 65% of current energy use as C-neutral electricity
    • Requires major investment and infrastructure to meet potential demand of C-neutral electricity
      • need pragmatic approach to prioritize electrification target and develop technology solution

Decarbonizing industrial sectors: “menu” of options

Electrification and Decarbonization Solutions for Industry – Review of the Common Issues and Potential Solutions – SEA Workshop – April 5-7, 2022

7

Alternative Feedstock

    • Use non-fossil carbon source, e.g., bio-oil/gas/mass, captured CO2
    • Use carbon-free hydrogen, e.g., replace NG to decarbonize ammonia production

Energy Efficiency

    • Improving EE will reduce energy use and resulting emissions

Electrification of Heat

    • switch to furnaces, boilers and heat pumps that run on carbon-neutral electricity
    • new production process with electrification of heat, e.g., electric cracker with e-furnace & compressor, plasma kilns

Disruptive

Process

    • novel low-C technologies to replace current processes, e.g., high-T heat pump/furnace or plasma assisted reforming, electro-catalytic synthesis of olefins and alcohols; microwave or plasma assisted pyrolysis and drying, plasma or direct electrical heating of ore, direct hydrogen reduction, IR curing

CO2 Capture

    • Capture from process emission: storage or use as source of carbon in circular carbon-economy
