Elektrolüüsereid

Elektrolüüsereid, often translated as electrolyzers, are devices that use electrolysis to split water into hydrogen and oxygen. This process involves passing an electric current through water, which breaks down the H2O molecules. Electrolyzers are a key technology in the production of green hydrogen, a fuel that can be used in various applications, including transportation, industry, and energy storage. The electricity used to power electrolyzers is ideally sourced from renewable energy sources such as solar or wind power, making the hydrogen produced carbon-neutral. There are several types of electrolyzers, including alkaline, proton-exchange membrane (PEM), and solid oxide electrolyzers, each with its own advantages and disadvantages in terms of efficiency, cost, and operating conditions. Alkaline electrolyzers are the most mature technology and are generally more cost-effective, while PEM electrolyzers offer higher efficiency and faster response times, making them suitable for dynamic renewable energy sources. Solid oxide electrolyzers operate at high temperatures and can achieve very high efficiencies, but they are less mature and more expensive. The development and deployment of electrolyzers are considered crucial for decarbonizing various sectors and achieving climate goals.
