PEM electrolysis is an advanced electrochemical process that uses a proton exchange membrane to split water into hydrogen and oxygen, powered by electricity. This technology, a specialty of Hyto Energy, is celebrated for its high efficiency, rapid response, and ability to produce high-purity hydrogen, making it a key enabler of green hydrogen production when paired with renewable energy. In PEM electrolysis, water is supplied to the anode, where it undergoes oxidation in the presence of a catalyst (typically iridium), producing oxygen gas, protons (H⁺), and electrons. The protons pass through the proton exchange membrane—a thin, selective polymer barrier—to the cathode, while electrons travel through an external circuit to maintain charge balance. At the cathode, protons combine with electrons (via a platinum catalyst) to form hydrogen gas, which is collected for use. A defining feature of PEM electrolysis is its high efficiency, often exceeding 80%, meaning a large portion of the input electrical energy is converted into hydrogen’s chemical energy. This, combined with its rapid startup and shutdown capabilities, allows it to dynamically match the variable output of renewable energy sources like solar and wind, maximizing the utilization of clean electricity and minimizing waste. PEM electrolysis produces hydrogen with purity levels up to 99.999%, eliminating the need for additional purification steps, which is critical for applications such as fuel cells. Hyto Energy optimizes PEM electrolysis systems for durability and scalability, with modular designs that can be tailored to small-scale distributed production or large industrial projects. For those seeking to harness renewable energy for hydrogen production, PEM electrolysis offers a flexible and efficient solution.
