They are also used in test stands for fuel cells' development and quality control.
Hydrogen plays a decisive role in overcoming the challenges of energy transition. Whether used to store energy or for future mobility, hydrogen is an environmentally friendly solution with enormous potential. However, it is important that green hydrogen is produced efficiently using climate-neutral methods. The benefits of hydrogen as an energy source of the future are significant: It has a high energy content of 33 kWh/kg, in contrast to diesel fuel, which has only 10 kWh/kg. Compared to combustion engines, a 5 kg tank of hydrogen can reach ranges of around 650 km in conjunction with an efficient system of fuel cells and an electric drive. Hydrogen electrolysis is also an excellent way to store surplus electricity from renewable energies. LAUDA's innovative constant temperature solutions address challenges in handling hydrogen during refueling.

Our state-of-the-art cooling solutions for hydrogen filling stations make sure that the hydrogen infrastructure operates smoothly and efficiently. Since 2015, we have been developing and continuously optimizing our cooling systems through pioneering work. The modular systems are extremely flexible and can be adapted or extended to suit different pressure and temperature requirements. Our cooling solutions are utilized not only in conventional filling stations for both passenger and heavy-duty transport vehicles but also in tube trailers and for refueling trains. One key feature of our solutions is the efficient cooling of the compressors required to generate pressure by our LAUDA Ultracool process circulation chillers. We are therefore able to offer a holistic solution from a single source.
Benefits of indirect cooing
Cooling unit is a direct evaporator that can have a redundant design to ensure maximum reliability and enable continued operation of the tank system, even during service campaigns. It also offers better partial load efficiency, which makes sense from an energy perspective, especially when demand is low. It is therefore possible to install just one cooling unit in a refilling station and add another module to the system as demand increases. The cooling unit has two refrigerant circuits in a cascade connection, which are operated with natural refrigerants.
Three-way valve, designed primarily to pre-cool the cold accumulator in standby mode. Even if there is a decrease in load at the fuel pump, the excess cooling capacity can be used to regenerate the cold accumulator during the refueling process in order to start subsequent refueling directly without a break.
A wide variety of protocols can be installed at the fuel pumps, for example, 1x350 bar and 2x700 bar for LDV and HDV. One possible solution, e.g. at high flow speeds and large volumes, can be implemented via the upstream valves so that power is channeled to the fuel pump where it is needed.
Pump module, can be fitted with a powerful pump or with an additional redundant pump to increase reliability. The pump capacity is designed specifically for the application.
The volume of the cold accumulator containing heat carrier fluid can be adjusted according to the tank cycles and the accumulator can also be refilled via the three-way valve during the ongoing refueling process to achieve efficient back-to-back refueling.
Cooling units can be located away from the fuel pumps. In terms of energy efficiency, distances of usually 50 m are possible. Explosion or noise protection can often be avoided as a result.

Pioneering hydrogen refueling for the future of mobility
High-performance hydrogen filling stations are key players in efforts to reduce carbon emissions in the European transport sector. The ›RHeaDHy‹ project, funded by the European Union, is playing a leading role in revolutionizing hydrogen refueling for heavy-duty trucks. We are primarily focusing on developing a high-performance cooling system that forms the basis for high-performance fueling protocols. Intensive simulations are conducted in advance to verify the refueling process that has been developed. The next step will be to install two high-performance refueling systems in France and Germany to test these innovative protocols in practice. The RHeaDHy project, therefore, represents a decisive step in the development of hydrogen refueling systems and paves the way for a promising future in the industry. We are proud to be part of this important process and look forward to shaping the mobility of tomorrow.
