Human activities produce greenhouse gases

60 ± 7 GT CO2 eq/year

IPCC estimates net global greenhouse gas emissions in 2019

We need to decrease

16.4 Gt/year by 2030

Hydrogen can play a key role in reducing greenhouse gas emissions.

Hydrogen is clean, flexible and energy efficient and holds tremendous potential in reducing greenhouse gas emissions.
Hydrogen will be a key contributor to the energy transition

Hydrogen economy is the KEY

Paradigm Shift

Transition from Carbon Economy to Hydrogen Economy

  • Carbon Economy

    Based on carbon resources
    (petroleum, coal, natural gas etc.)

    Dependency on imports (97%)

    Centralized energy supply and demand (requires large investment)

    Many geographical / location constraints

    Contributes to greenhouse gas emission and air pollution(i.e. CO2, NOx, SOx, etc.)

  • Energy paradigm

    Energy supply

    Environmental impact

  • Hydrogen Economy

    Focuses on carbon neutrality with clean hydrogen

    Contributes to energy independence through domestic energy production

    Decentralized energy supply and demand Minor geographical/ location constraints

    Reduce greenhouse gas emission
    (eco-friendly)

For Hydrogen Economy,
We need plentiful and affordable clean hydrogen

Featured Hydrogen Production Technology

Current hydrogen production methods are either
high cost or cause high CO2 emissions

  • Grey Hydrogen
    -
    Methane reforming

    Low cost, Most widely used method

    Too Much CO2
    Emits 9 kg of CO2 for every 1 kg of hydrogen

  • Blue Hydrogen
    -
    Methane reforming
    with CCS

    Reformation technologies such as SMR, POX, etc. = A proven highly efficient hydrogen generation technology

    The difficulty of collecting and storing CO2
    If CCS rate increase by more than 80%,
    costs will spike

  • Turquoise Hydrogen
    -
    Methane pyrolysis
    with solid carbon

    Solid carbon product → Zero emissions of CO2
    A lower cost technology compared to water electrolysis

    Difficult to maintain and manage
    (1,000-1,500 ℃ ultra high temperature process)
    Creates low quality solid carbon

  • Green Hydrogen
    -
    Renewable power electrolysis,
    Biomethane reforming

    CO2 not produced
    (Only when associated with renewable energy)

    When associated with renewable energy,
    there is no carbon emission High impact on renewable energy environment
    (geographical limitations)

※ In Europe, in case of hydrogen production using biomethane, regarded as green hydrogen, carbon processing is required
Hydrogen eco-friendliness depends on the
Hydrogen Production Method
