Key drivers of green ammonia
• Global production: > 170 million t/year
• Consumption of about 1.4 % of world-wide
consumed fossil energy carriers
• CO2 emissions: > 400 million t/year CO2
(~ 1.4 % of global energy-related CO2 emissions)
• 80 % of produced ammonia used for fertilizers
• Higher awareness of CO2 Emissions issue
• CO2 taxes
• Production without CO2 Emissions *
• Increasing need for fertilizers
• Local production
• Additional use for ammonia as an energy carrier:
− Direct
− Indirect
Current situation of Ammonia Business Possible Future
*depending on E-power source

Our design philosophy
• Standardized, skid mounted electrolysis modules for cost efficient deployment at site.
• Area required for a 100 MW electrolysis plant is about 3000 m².
• Optional downstream processing equipment: compression, oxygen removal and drying
5 MW Standard Module 20 MW+ Standard Trains
New frontiers and opportunities
Alkaline Water Electrolysis Technology
• Proven zero-gap technologyA proven system and an existing supply chain:
>200,000 of elements manufactured1
>1.2 million m² of electrodes produced1
>600 MW can be installed each year2
• Introduction of
high efficiency cathode design and
coating (with De Nora) for hydrogen
evolution
• Introduction of
high efficiency anode coating (with De
Nora) based on proven chlorine
technology
• Optimized high-performance
separators and diaphragms based on
proven design

Experience in
O&M
• long lasting experience in O&G
business
• High density of best educated
O&M personnel
• Population density at the lower
end
• High urbanization resulting in
sufficient space for large scale
installation of renewable power
plants
• Infrastructure fits perfectly as
adopted to requirements in
O&G business including long
distance supply lines
• long lasting experience in O&G
business
• All EPC-Contractors are
available for installation works
• High competition
New frontiers and opportunities
Key drivers in GCC
• High availability expected due
to very stable weather
conditions
• GCC belongs to those countries
with highest availability
• Efficiency can be further
increased by proper energy
storage solutions
• Offtake for electric power in
close proximity no issue
• Offtake for hydrogen or
ammonia also no issue as
required for O&G business
• New market for green ammonia
considered as green energy
carrier

New frontiers and opportunities
Key drivers in GCC
• GCC states announced to
invest in renewables
• Sustainability gets higher
recognition worldwide
• Lower competitiveness
expected compared to natural
gas cost
• Green ammonia could be
considered as a premium
product
• CO2 taxes issue might change
the business model completely

Conclusions
Well experienced and educated engineers available to operate green ammonia plants
Well positioned with regard to land and infrastructure availability
Good availability of Contractors
High availability and efficiency expected in renewable power generation
Good integration possibilities in existing ammonia plants resulting in good offtake situation
Highly supported by governments also in GCC
OPEX higher depending on electric power cost – right now in favor for natural gas
CO2 tax might become an issue, Green Ammonia labeling could also be premium
