Towards Net-Zero
Based on carbon resources
(petroleum, coal, natural gas etc.)
Dependency on imports (97%)
Towards Net-Zero
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
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
