Compact hydrogen refuelling
Thanks to the advanced printed circuit technology, an Alfa Laval HyBloc heat exchanger is 85% smaller than a comparable shell-and-tube heat exchanger.
This highly compact design maximizes flexibility when designing the complete refuelling system and the unit is easily integrated, e.g. in the dispenser casing. Unlike a shell-and-tube heat exchanger, the HyBloc is always installed above ground, eliminating the need for underground installation and significantly reducing civil work and associated costs.
Withstanding pressures of up to 1,250 bar, an Alfa Laval HyBloc enables system designs for operations at 350 bar (H35), 700 bar (H70) or even higher. Its high-pressure capabilities ensure short filling times and make it future-ready in case new standards with higher pressures are developed.
The HyBloc range comprises four models, offering solutions for all capacity needs. Our experts help you select the ideal model according to your cooling fluid, capacity requirements, and other specifications to ensure maximum performance.
Safe hydrogen handling
Hydrogen is highly explosive when mixed with air, meaning rigorous safety measures must be taken when handling the gas. The safety of the Alfa Laval printed circuit heat exchangers has been thoroughly proven over more than 15 years in demanding fuelling applications, including fuel gas supply for large ships and land-based natural gas systems for industrial and domestic use.
The HyBloc design is based on OptiBondTM diffusion welding of the heat transfer plates. This process merges the grain structures of the plates, forming a single solid block capable of withstanding extremely high pressures. As a result, high pressures are managed equally well on both the cool and warm sides, eliminating the need for pressure relief valves.
A revolutionary approach to hydrogen refuelling with HyBlocks
Clean energy
With expectations that green hydrogen could represent up to 24% of the energy market by 2050, the demand will continue to grow at a rapid pace.
PowerDense
Maximum performance under maximum pressure. Improves sustainability with the smallest metal footprint design, still capable of withstanding hydrogen pressures up to 1,250 bar.
ReFuel+
Higher back-to-back throughput for increased profitability. Low thermal mass in a highly responsive and compact solution enables greater capacity and reduced wait time between customers, extending the number of daily back-to-back refuels.
