Solution
•
demand driven, conventional
electrical power generation;
negligible share of renewables; no storage required
•
increasing share of renewables; waste of excess
energy; mid- and long-term
energy storage mandatory
•
efficient integration of
renewables and avoidance
of energy waste by making it
long-term storable
•
more than 98% of hydrogen
production based on CO2
intensive steam reforming
•
commitment to CO2
reduction targets, constant
growth of hydrogen market
•
•
global transportation based
on gasoline and diesel only
•
innovative e-mobility
concepts
CO2 free production of
“Green hydrogen” for all
industrial requirements and
to support sustainable, zero
emission transportation
solutions

Key Statements
NEW
SILYZER 200
/ Methane
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
The future CO2-optimized energy scenario will require smart solutions

SILYZER and hydrogen together are an unbeatable
combination to achieve major targets
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
Environmental protection +
• local onsite production of
CO2-free hydrogen without
using hazardous material,
such as caustic potash,
avoids extensive transports
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
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
