H-TEC SYSTEMS Presents a Modular Hydrogen Electrolyzer for Large-scale Projects of
10 MW Upwards
Efficient and reliable hydrogen production with H-TEC SYSTEMS PEM-Elektrolyzers
Hydrogen will play a decisive role in the economy of the future.
The goal of reducing greenhouse gases to a greater extent will
ensure that legal requirements for emission limits become more
stringent in all sectors. In view of the sector targets enshrined in
the Climate Protection Act, the pressure on industry is also increasing,
which will entail a rapid ramp-up of hydrogen production
in the multi-megawatt range.
As a pioneer in the industry and specialist in PEM electrolysis
systems, H-TEC SYSTEMS has duly recognized the growing
need and, through its new Modular Hydrogen Platform (MHP),
has realized a scalable system for the industrial production
of green hydrogen. The standardized blocks each have an
electrolysis performance of 10 MW and can be combined into
systems with an electrolysis power output of 100 MW and more.
The H-TEC SYSTEMS MHP electrolyzer offers an outstanding
system efficiency, high availability and proven maintenance
concept. The new system ensures exceptionally low hydrogen
production costs as well as stable operation.
Modular concept simplifies scaling and reduces costs
The highly standardized 10 MW blocks from H-TEC SYSTEMS
are based on the tried and tested S450 stack technology which
has already proven itself in the market. The new system is
designed for particularly easy indoor installation by means of
pre-assembled skids. Each 10 MW block is equipped with integrated
process water treatment and an electric power supply. In
addition, the system can be supplemented with fresh water and
hydrogen treatment equipment as well as process heat recovery
or oxygen utilization as and when required. One of the most
important features of the MHP is the high system efficiency of

77 percent (<51kWh/kg) at 30 bar pressure which is far above
the standard values.
Redundancy concept guarantees system reliability
Aside from the efficiency aspect, the system availability of an
electrolyzer plays a decisive role. It is here that the MHP offers
a unique redundancy concept. In the event of a stack failure
within a 10 MW block as well as scheduled maintenance or
inspections, a defined part of the installation can be shut down
while the rest of the electrolyzer continues to operate. Through
this concept, the systems can achieve almost full performance
even in the event of a fault which represents crucial added
value for customers based in the renewable energy and industrial
sectors. Furthermore, the system is looked after by experts
from H-TEC SYSTEMS using a comprehensive maintenance
service program.
