Power supply

Power supply

Machines and vehicles being powered by either electric batteries or hydrogen only makes sense from a climate protection perspective if the electricity and hydrogen used can be made available in a CO2-neutral way.

While climate-friendly power generation with wind power and solar power plants is already an established industry outside of electromobility, using stationary battery storage to level out fluctuations in the generation of renewable energy and generating hydrogen by means of electrolysis on a large-scale in an environmentally friendly way both represent uncharted territory. Electrolysis plays a key role here, as hydrogen generated using CO2-neutral methods serves as a fuel for mobility, an energy source for supplying electricity and heat, a substitute material in industrial processes such as steel production and a raw material in the chemicals industry. Fuel cell power plants make it possible to supply electricity and heat to households and industrial companies in a safe and climate-friendly way.

HYDAC products for these applications cover cooling systems for battery storage, fuel cell power plants and electrolysis systems, sensors and filtration solutions for hydrogen applications and mounting technology for power cables and hydrogen tanks.


Components and systems for battery storage

The storage of electricity will play a major role in the future mains power supply, as the percentage of renewable energy continues to increase. To rapidly balance out power generation and power consumption (grid stabilisation), battery storage is increasingly being used. Power plant operators can, for example, use the storage for grid stabilisation and at the same time run their power plants more smoothly. Industrial companies can use the systems both to provide uninterrupted power supply and to increase their internal consumption from installed photovoltaic plants and smooth out load peaks (“peak shaving”) in order to lower the costs for their electricity supply. In the context of quick charging stations for battery-powered vehicles, battery storage can be used to reduce the high peaks that strain the power grid during charging and thus avoid an expensive grid expansion.

Regardless of the particular application, we are your contact for the fluid-cooling of battery modules and of the associated frequency converters that are needed for the grid connection. We can provide compressor cooling systems (chillers) and fluid/air cooling systems, plate heat exchangers and liquid cold plates.

Components and systems for electrolysis plants

With expertise in cooling systems, heat exchangers and separators/filtration, HYDAC can provide innovative system solutions for the condensation drying of hydrogen and oxygen. This involves using heat exchangers with a connected cooling system to cool down the product gases so that the water they contain can be condensed out and removed by a separator.

On the hydrogen side, there is also an extensive portfolio of pressure sensors with nominal pressures from 16 to 1050 bar.

Well-established mounting systems from HYDAC Accessories make it possible to mount power cables and hydrogen containers quickly and securely, in little space.


Modular cooling systems

Modular table coolers with microchannel heat exchanger elements that have been optimised for low-temperature cooling by means of water-glycol are on offer. All coolers are available in a range of designs such as in low-noise or heavy-duty versions.

Tailored cooling systems for integration in system set-ups and containers are also on offer. In this regard HYDAC is able to draw on its many years of experience in the field of gen-sets.

The cooling box is also a central cooling solution in multi-MW systems.

Particle filters and fluid separators for hydrogen

Customised and standard combinations of cyclone separators and coalescence filter elements for separating hydrogen and oxygen from DI water or KOH lye also form part of HYDAC’s offering.

Components and systems for fuel cell power plants


Hydrogen and fuel cells 
will play an important role in sustainable power supply in the future. , HYDAC provides an extensive portfolio of components and systems, ranging from tank mounting systems, filtration and sensors, for both mobile and stationary use, to complex cooling systems with DI-water circuits.


Mounting technology for tank systems

To transport the hydrogen needed for the fuel cells, type-3 or type-4 containers are currently used, depending on the application. With our unique flexible stainless steel straps with patented quick release bolts combined with individually developed neck mounts, we can realise mounting systems that allow the containers to expand and contract while keeping them securely held in the event of impact.


Particle filters and fluid separators for hydrogen

HYDAC is offering the leading technology for filtering gases in hydrogen applications up to 1,050 bar. The design of the filters provides maximum filter area in the most compact dimensions and is noted for excellent process stability, top quality permeate and minimal pressure loss. 


Pressure sensors for hydrogen

With over 30 years of experience in developing and producing pressure sensors, HYDAC Electronic has established a new series of hydrogen pressure sensors on the market. The pressure sensors are now used worldwide in fuel cell vehicles (with EC79/2009 certification) and stationary applications (ATEX, IECEX, CSAUS).
