The green hydrogen sector is poised for significant growth, with a forecasted total capacity of 175 million tonnes per annum. This expansion is underpinned by the decreasing Levelized Cost of Hydrogen (LCOH), aiming to make green hydrogen competitive with fossil fuel-derived hydrogen. Digital solutions are emerging as key tools to drive efficiency and manage costs in green hydrogen facilities. However, a major challenge remains in rapidly upscaling unproven technology in the sector, necessitating a shift from reliance on subsidies to sustainable cost reduction strategies. Worley's Green Hydrogen Center of Excellence underscores the importance of reducing production costs to ensure long-term competitiveness with fossil fuels. By leveraging data analytics and innovative solutions like the Asset Optimization Center (AOC), operators can tackle inefficiencies and optimize green hydrogen production. The AOC, developed in collaboration with industry leaders like IBM and ABB, offers real-time insights to enhance operational efficiency, address challenges in green Power-to-X assets, and ultimately drive down the cost of green hydrogen production.
