ALKALINE
thyssenkrupp electrolyzer system
DESCRIPTION: thyssekrupp has developed a modularized
and cost-efficient solution for large scale hydrogen
production based on their chlor-alkali electrolysis
technology and experience in industrial large-scale
electrolysis applications. The 20-MW alkaline water
electrolysis unit is offered as a prefabricated skid-mounted
module for simplifying construction of new hydrogen
plants and minimizing costs. The basic 20-MW modules
can be added up to several hundred megawatts and up to
gigawatt scale for large scale hydrogen generation.
ADVANTAGES/KEY FEATURES:
* Single-element design permits single cell
replacement
* 8-yr lifecycle between refurbishment of cell
elements of the stack
* Instead of an entire stack replacement,
single elements allow refurbishment of specific
components
* Robust, proven, reliable and advanced
alkaline technology
* Higher efficiency than PEM electrolyzers at
current densities comparable to PEM technology
Efficiency of this technology is about 79% based
on the higher heating value of hydrogen
* Low plant footprint vs. other alkaline technologies
and is comparable to PEM technology
* 20-MW electrolyzer module offers a
wide operating range of 10%-100%
* Modular, skid mounted design
* Low power consumption
* Fully automated operation
* Fast dynamics suitable to renewable
power sources
* Production capacity of 1 GW electrolysis cells
per year currently and 5 GW by 2025
*Specifications are subject to change
* EPC turnkey execution worldwide
* Global service.
SPECIFICATIONS:
* Module capacity: 20 MW at end of life
* Nominal power consumption at beginning
of life (direct current): 4.5 kWh/Nm3
* Nominal production rate: 4,000 Nm3/hr
* H2 purity at electrolyzer-outlet: 99.9% (dry basis)
* H2 purity at electrolyzer-outlet after treatment
(optional): up to 99.999%
* Water consumption rate: 9 kg/kg of H2 produced
* Electrolyte: Potassium hydroxide
* Ambient temperature: Standard 40°C
(variable depending on projects)
* Hydrogen delivery pressure: Approximately
1.3 bar(a), but compression option is offered.
* Life expectancy: 20 yr-25 years
* Footprint: About 2,500 m2 per 100 MW, including,
transformer, rectifier and compression to 30 bar
APPLICATIONS/INDUSTRIES SERVED: Industries
served include petrochemicals, refining, transportation/
mobility, synthetic fuels, ammonia/fertilizer, steel/metals
production, renewable energy grid, chemical/industrial
processes, upgrading biomass/biofuel/biomethane/
biomethanol production, commercial distributed gases,
thermal processing and utilization of heat.
ELECTROLYZER IN-UNIT ACCESSORIES: Includes
water separator, transformer, rectifier and offer option
for purifier, deoxidizer, dryer and compression system.
SERVICES PROVIDED: Feasibility studies, detail
engineering, installation, EPC for hydrogen generation
plants, and downstream plant and monitoring; service
and maintenance, parts replacement and cell separators
for electrolyzer system through entire plant life with
supply chain equipped to provide large scale hydrogen
projects and customized project support.
