The green hydrogen sector is poised for significant growth but faces challenges in production costs, operational inefficiencies, and power forecasting difficulties. Honeywell's recent solutions showcased at the Honeywell Users Group (HUG) meeting in Madrid aim to tackle these issues. The sector's current small installed capacity is expected to grow exponentially, with 865 announced projects from 2023 to 2030. China leads in installed capacity, with other hotspots being Europe, India, Australia, and the United States. The focus is on reducing the levelized cost of hydrogen (LCOH) to less than $2/kg, with an expected decline to $2.6 or $2.7 by the end of the decade. Honeywell's offerings include Concept Design and Optimization, Plantwide Control and Optimization, and Electrolyzer Control System, addressing various aspects from design to operation. These solutions aim to reduce costs, enhance efficiency, and improve the overall performance of green hydrogen plants.
