SILYZER PEM electrolyzer is a key component to

solve the sustainability challenges of today

Yesterday

• demand driven, conventional electrical power generation; negligible share of renew-ables; no storage required

• more than 98% of hydrogen production based on CO2 intensive steam reforming

• global transportation based on gasoline and diesel only

Today

• increasing share of renew-ables; waste of excess energy; mid- and long-term energy storage mandatory

• commitment to CO2 reduction targets, constant growth of hydrogen market

• innovative e-mobility concepts

Solution

• efficient integration of renewables and avoidance of energy waste by making it long-term storable

• CO2 free production of “Green hydrogen” for all industrial requirements and to support sustainable, zero emission transportation solutions

SILYZER completes energy storage portfolio and

supports tailored solutions for all major industries

Large scale storage can only be

addressed by Pumped Hydro,

Compressed Air (CAES) and

chemical storage media like

Hydrogen and Methane

The potential to extend pumped

hydro capacities is very limited

Hydrogen is used in many main

industries as a reductive or

protective gas or is used as an

input in synthesis processes;

onsite hydrogen production is a

promising alternative to

trailer/truck supply

Key Statements

/ Methane

The future CO2-optimized energy scenario will require smart solutions

SILYZER and hydrogen together are an unbeatable

combination to achieve major targets

Optimization of costs

• low OPEX and “total Costs of

Ownership (TCO)” due to

minimal installation efforts,

maintenance-free stacks,

clean and safe operation,

robustness, pressurized mode

until 35 bar, lifetime specified

with more than 80.000 hours

+

Increasing revenues

and turnover

• due to extremely dynamic

operation behavior, SILYZER

can be used as a load within

intelligent energy management

systems (EMS) for the grid

+

Investment protection

• utilization of wind energy

turbines or solar panels

even during forced

curtailment periods due to

grid imbalance increases

operation hours and delivers

hydrogen as a valuable

product further more

+

Environmental protection

• local onsite production of

CO2-free hydrogen without

using hazardous material,

such as caustic potash,

avoids extensive transports

SILYZER produces hydrogen as a multi-purpose

energy carrier for industry, mobility and grid services

H2 production: no CO2, independent, efficient , onsite

• Chemical synthesis (e.g. ammonia, fertilizer, methanol)

• Petrochemical processes (e.g. cracking)

• Flat glass, nonferrous metal (protective and reductive gas)

• Food & Beverages (hardening)

H2 application: a sustainable fuel for transport concepts

• CO2 free mobility; Renewable fuel concepts

• Sustainable and pollution-free Public Transport

• Fuel Cell based in-plant logistics (forklifts, floor conveyors)

• Reliable, safe e-mobility: “fast-to-refuel” cars with long ranges

H2 conversion: stabilizes the power grid

• Grid balancing capability (dynamical behavior in milliseconds)

• Optimization of asset utilization in renewable energies

• Storage of medium- and long-term overcapacities (TWh)

• Power-to-hydrogen and Power-to-gas as future key concepts
