Hydrogen – hydraulic solutions for greater sustainability Hydrogen

Hydraulic solutions for greater sustainability

Our solutions for the hydrogen industry

Green hydrogen from renewable energies is a key component in achieving global climate targets. It is a convincing alternative to fossil fuels, particularly in heavy goods transportation. As with electromobility, a nationwide infrastructure is crucial for success. Hydrogen must be stored and transported under high pressure or in frozen, liquid form – refueling must be efficient, safe and as fast as possible.

Bosch Rexroth contributes decades of experience in industrial hydraulics and offers customized, innovative solutions for the compression of liquid and gaseous hydrogen – from robust, safe components to engineering support and complete servo-hydraulic, turnkey solutions.

 

Hydrogen fueling stations and testing systems

Electrohydraulic drive systems for piston compressors and cryopumps

Electrohydraulic drive systems for piston compressors and cryopumps

The approach for systems from approx. 10 kg H2/h is based on a displacement-controlled drive with variable speed and/or variable displacement. This avoids the losses that occur when a control valve is used to manage the drive. The electrohydraulic solution allows needs-based power control. Power electronics and digital control systems also come from Bosch Rexroth. The latter play a key role in ensuring smooth running and exact process control. This way, the piston movement makes optimum use of the compression space and achieves the highest possible gas-side efficiency. A suitable compressor drive cylinder can be supplied for every electrohydraulic system.

Compact drives for small systems

Compact drives for small hydrogen systems

For smaller daily production quantities in the range of up to 10 kg H2/h, the Bosch Rexroth drive portfolio includes highly efficient complete systems in the form of servohydraulic axes (SHA). These particularly compact solutions concentrate a variable-speed drive comprising a servo motor, hydraulic pump, control block, synchronous cylinder and minimal oil volume in a very small space. Customer-specific compressors are mounted on the cylinder itself.

The SHA can be used to compress not only hydrogen, but other gases too. The SHA is already well established in the market. With its extremely compact size, it is particularly suitable for retrofitting in modular and highly mobile systems. Thanks to displacement control, our SHAs are very energy efficient. Another strength lies in their quick installation and commissioning. Firstly, they can be installed without pipework. Secondly, the pre-configured SHA is a “plug & produce” solution and thus requires no programming work. Instead, it is simply parameterized on site and is ready for immediate use.

Double rod cylinder – CGV

Double rod cylinder for medium hydrogen volumes

The CGV double rod cylinder is a durable and energy-efficient solution for compressing gases. It drives the flange-mounted gas compressor with high repeat accuracy and oscillating movements. The pre-tested cylinder, which is adjusted for end position accuracy, is easy to install regardless of position. Integrated leakage connections for gases on the cylinder simplify the design of the compressor heads. The cylinder position is determined by switching sensors. Forces of up to 2,500 kN can be realized. Speeds of up to 0.8 m/s are possible. CGV double rod cylinder are the optimum solution for your gas compressor. Durable - Powerful - Efficient.

Your Benefits:

  • Specially optimized double rod cylinder for driving compressor systems
  • robust design for maximum service life
  • Position-accurate movement thanks to end position detection for maximum output and efficiency in the compression process
  • ATEX certification available
  • optimized for operation in combination with CytroCore
Servo hydraulic drive system – CytroCore

Servo hydraulic drive systems for medium hydrogen volumes

Bosch Rexroth also offers variants developed together with partner companies for medium and smaller outputs. The 75 kW CytroCore compressor drive can be used to compress both liquid and gaseous hydrogen. For optimum energy efficiency, Bosch Rexroth relies on so-called displacement control. In addition, the drive systems for compressors require less than one square meter of installation space and are much quieter than conventional drive systems. After a one-off parameterization, they are ready for immediate use. They communicate with the control system for the hydrogen filling station via open interfaces.

Your Benefits:

  • Compact servo-hydraulic system solution with electric and hydraulic drive technology and software for positioning a double rod cylinder
  • High power density enables high movement speed for high compressor performance
  • Small footprint, low oil volume
  • Noise optimized components and design
  • Optimized for operation in combination with CGV cylinders
CryoPump Station with a cryogenic pump

CryoPump Station with integrated cryogenic pump

The CryoPump Station revolutionizes hydrogen infrastructure with innovative technology tailored to the challenges of hydrogen mobility. Our cryopump technology enables economical hydrogen refueling, reduces operating costs by up to 70 % and reduces the space requirements of refueling stations, facilitating integration into existing structures. It was developed with Firstelement Fuel, the leading operator of hydrogen refueling stations.

Your Benefits:

  • Reduced load cycles and eliminated dead volume increase efficiency up to 95%.
  • With 4000 operating hours before maintenance, it significantly outperforms conventional systems.
  • Minimized boil-off losses thanks to optimized thermal insulation.
  • Direct vehicle refueling possible without additional high-pressure storage tanks; this reduces complexity and costs.
  • With a pumping capacity of 600 kg/h, it is five times more powerful than competing technologies.
  • Turnkey construction and space-saving design (<11 m²) enables use in urban areas.
  • Sound pressure level below 65 dB(A) improves environmental compatibility.
  • Conveying of liquid and gaseous hydrogen for new storage concepts offers flexibility for the future.
