The Global Hydrogen Review 2024 highlights the growth and challenges in the global hydrogen sector. While demand continues to be driven by traditional sources like fossil fuels, there is a notable rise in low-emissions hydrogen production. Electrolysis projects are at the forefront of this growth, with significant announced capacity and increasing final investment decisions. Fossil fuel projects with carbon capture are also on the rise, especially in North America and Europe. Despite this progress, the sector faces hurdles in project execution, including delays and cancellations, financial barriers, regulatory complexities, and operational challenges. To achieve the projected targets by 2030, the sector needs to grow at an unprecedented rate, surpassing even the fastest expansion phases of solar PV. Clearer demand signals, improved financing mechanisms, regulatory clarity, and addressing operational issues are vital to overcoming these obstacles and realizing the full potential of the global hydrogen market.
