"Laser Systems" in partnership with the Aluminum Association made a presentation at "Neftegaz"

As part of the business program of the exhibition "Equipment and Technologies for the Oil and Gas Complex" / "Neftegaz-2022", the company presented to the audience a report on the principles of operation of a gas station with an autonomous module for producing high-purity "green" hydrogen.

Alexey Boreysho, Deputy Chairman of the Board of Directors of JSC Laser Systems, spoke about an autonomous power module designed to supply high-purity hydrogen to stationary and transport facilities equipped with hydrogen fuel cells. The use of an autonomous module ensures the safe operation of objects, allowing them to be controlled in an automated or remote mode. In addition, capital and operating costs are reduced, and the service life of equipment is increased.

The production of hydrogen is based on the reaction of hydrothermal oxidation of powdered aluminum with water. As a result, aluminum hydroxide and hydrogen are formed, and a certain amount of heat is also released. In addition to high-purity hydrogen, commercially valuable finely dispersed aluminum oxyhydroxide, boehmite, is formed, which is an environmentally friendly product. Boehmite can be recycled or used in its original form as a sorbent and catalyst for petrochemicals, a component in the production of ceramics, an abrasive powder for processing, or a filler for the paint industry. The reaction is carried out at elevated temperature and pressure in a hydrothermal reactor by continuously supplying an aqueous suspension of aluminum powder into it and continuously withdrawing the reaction products: hydrogen, boehmite and residual water in the form of steam.

The thermal effect of the reaction per unit mass of aluminum (Q = 15.32 MJ/kg) can be used to create cogeneration plants that provide stations with electrical and thermal energy. An experimental unit for continuous production of hydrogen with a capacity of up to 100 nm3/hour has already been created and successfully tested. How to use heat? For example, in generating plants, to obtain hot water supply or to generate electricity using a turbine - this option allows you to create an autonomous system that does not require electricity. A hydrogen production station has a number of advantages: energy independence and mobility, technology scalability, no carbon footprint, and the ability to produce high-purity hydrogen suitable for fuel cells.

The Laser Systems company also took part in the National Oil and Gas Forum, which is an additional platform for the NEFTEGAZ exhibition with thematic conferences and round tables, which this year were devoted, among other things, to hydrogen energy development strategies.
