An alkaline electrolyser is a well-established hydrogen production system that uses an alkaline electrolyte (typically potassium hydroxide, KOH, or sodium hydroxide, NaOH) to facilitate the electrolysis of water. Hyto Energy’s alkaline electrolysers are renowned for their reliability, cost-effectiveness, and suitability for large-scale industrial hydrogen production, making them a trusted choice in the hydrogen industry. The operational principle involves applying an electric current to two electrodes immersed in the alkaline solution. At the anode, water molecules are oxidized to produce oxygen gas and hydroxide ions; at the cathode, these hydroxide ions react to form hydrogen gas. A porous diaphragm separates the electrodes to prevent the mixing of hydrogen and oxygen, ensuring safe operation while allowing ion flow to maintain the electrochemical reaction. One of the primary advantages of Hyto’s alkaline electrolysers is their use of low-cost materials: the electrodes are typically made from nickel or nickel alloys, avoiding the need for expensive precious metals. This, combined with their tolerance for lower-purity feedwater, significantly reduces both initial investment and operational costs. These electrolysers excel in continuous, high-volume operation, making them ideal for large industrial applications such as ammonia synthesis, methanol production, and oil refining. They are also deployed in large-scale green hydrogen projects when paired with stable renewable energy sources (e.g., hydroelectric power), where their steady performance ensures consistent hydrogen output. While alkaline electrolysers have a slower response to power fluctuations compared to PEM systems, their long service life (often 10–20 years) and proven track record make them a cornerstone of industrial hydrogen production. Hyto offers alkaline electrolysers in various capacities to meet diverse industrial demands. For detailed specifications and operational guidelines, contacting Hyto Energy is recommended.
