Conclusion

Agenda

New frontiers and opportunities


• 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



Leaders of European Union and the G8 announced an objective to

reduce GHG emissions by 80% below 1990 levels by 2050 Source: www.roadmap2050.eu

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


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

Key drivers in GCC

Land and

Availability

Availability of

EPC Contractors

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


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

Renewables

AvailabilityOfftake


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
