Accelerating clean energy expansion through actionable insights, strategic intelligence, and world-class events. Formerly World Hydrogen Leaders, now evolving into the Horizons Clean Energy Expansion Series as part of S&P Global Energy, we bring together global decision-makers to support the build-out of next-generation energy systems. World Hydrogen Leaders established itself as a leading convening point for hydrogen-focused events and industry collaboration. Today, as part of S&P Global Energy, our portfolio is evolving to reflect the scale, urgency, and complexity of global energy growth and security. As energy demand rises and systems become more interconnected, the conversation is shifting from single-solution focus to delivering integrated, scalable energy systems. In response, our event portfolio is evolving beyond hydrogen alone. Introducing the Horizons Clean Energy Expansion Series - a redefined global events portfolio designed for stakeholders driving large-scale energy development and deployment. Hydrogen remains a critical pillar, now complemented by a broader agenda spanning electrification, CCUS, power and grids, storage, alternative fuels, nuclear, geothermal, and emerging innovations shaping the future energy system. Through the Horizons series, we bring together: • Senior decision-makers across energy, industry, finance, and policy • Market-critical insights on project development, investment, and regulation • High-level discussions focused on delivery, scalability, and execution • Global and regional perspectives on energy infrastructure build-out
