Minimising contamination
Haskel understands the importance of maintaining gas cleanliness during compression activities, we know fuel cells are sensitive to any type of gas contamination which is why it is imperative that the gas purity is maintained within the levels outlined in ISO 14687 and SAE J2719 standards.
We recognize that gas contamination is a particular concern within the industry, especially with hydraulically driven technology. Haskel’s full range of hydrogen compressors are designed specifically to prevent any cross contamination of the gas to ensure gas purity is maintained throughout the refuelling process.
Designing out risks during hydrogen compression
During the refuelling process hydrogen is compressed, transported and stored until point of use. Compression is achieved by moving hydrogen through a compressor that decreases the gas’ volume between the inlet and discharge, sometimes in several stages. Decreasing volume increases the gas’ static pressure and makes it possible to transport Hydrogen economically so that it can be stored in tanks, while compression also boosts the gas’ pressure up to levels that are required to fuel a vehicle. Gas purity must be maintained throughout the compression process.
In order to achieve this, our H-Drive and all Haskel hydraulically driven boosters have two distinct sections, the hydraulic cylinder assembly and the gas section.
