For more than a century, Parker Hannifin has drawn his way into industry, with a turnover of $ 19.1 billion and a presence in 44 countries. Through various industrial sectors, Parker is distinguished by its wide range of products, from nitrogen production equipment to filtration systems for the development of vaccines, including fittings and flexible for mobile machines or seal for aeronautics.
The story of Parker and Hydrogen dates back to the Apollo missions, when the company provided crucial equipment for the upper floors of the rockets as well as essential components for the hydrogen systems present in the on -board fuel cells. Thus, Parker Hannifin contributed to the first steps of Neil Armstrong on the Moon!
In his quest towards new horizons, Parker has created a branch dedicated to clean technologiesexploring alternative electrification and fuels such as natural gas and hydrogen.
What is the importance of purification in the hydrogen production process?
Hydrogen purification is essential to guarantee its integrity and protect the equipment that uses it. Throughout the manufacturing process, it is crucial to ensure that no impurity contaminates hydrogen, limiting particles to a maximum of 5 per million (PPM). Purification techniques include coalescence, drying and high temperature catalysis.
How does Parker Hannifin ensure the purity of water upstream of the hydrogen production cycle?
Thanks to our expertise in water purification, acquired through our maritime equipment, we offer complete purification systems including three filtration stages: particulate, by reverse osmosis and by deionization. The purity of the water is measured by its conductivity, which must be minimal to guarantee the purity of the hydrogen produced.
What are the specific challenges linked to the purification of hydrogen?
Water purified in large quantities should not come into contact with the CO2 Content in the air because carbonic acids could deteriorate the hydrogen production of electrolysis. Parker therefore recommends a nitrogen scanning of purified water tanks to maintain its quality. The purification of large -scale hydrogen also poses challenges, especially in terms of hydrogen flow to dry, which require the development of secure equipment and in accordance with use with hydrogen to prevent any risk of explosion.
How does Parker Hannifin are committed to the use of hydrogen at zero emission?
During the production of clean hydrogen, generated thanks to renewable energies, no carbon is issued. In use, we use an air filter for the cathode with specific filtration layers that hold the majority of pollutants, we moisten hydrogen, and we also filter the cooling liquid, which offers the battery a longer lifespan and without emission other than water.
What are the technologies used by Parker Hannifin to ensure the efficiency and sustainability of equipment?
We offer air and particle filters specifically designed to protect pollutants’ fuel cells. In addition, our filtration and drying solutions contribute to maintaining the performance and longevity of the equipment, while offering predictive maintenance recommendations to ensure optimal operation (replacement of filtering, drying elements, periodic visit to refrigeration systems, leak detection, etc.). We take up each technical challenge with passion: to propel clean technologies are our engine, anchored in our DNA.
