Clean hydrogen energy systems: Enable large-scale decarbonization of energy and industry.
Clean hydrogen energy systems represent the entire value chain dedicated to producing, storing, distributing, and utilizing hydrogen with a minimal carbon footprint. This includes production methods like electrolysis powered by renewable electricity (often called green hydrogen) or steam methane reforming with carbon capture and storage (often called blue hydrogen).
The goal is to fully decarbonize hard-to-abate sectors like heavy industry and long-distance transport. Developing a safe, cost-effective infrastructure for pipeline transmission and large-scale bulk storage is the central challenge. Success in this field is a crucial enabler for global transition to a sustainable, low-carbon energy portfolio.
FAQs:
Q: What is the difference between "green" and "blue" hydrogen within a clean energy system?
A: Green hydrogen is produced using renewable energy for electrolysis, while blue hydrogen is derived from natural gas with carbon emissions captured and stored.
Q: What major challenge in the energy system does clean hydrogen offer a solution for?
A: It provides a critical pathway for the decarbonization of heavy industrial processes and long-distance, high-energy-demand transportation sectors.
Q: What is a significant infrastructure component needed to realize a large-scale clean hydrogen system?
A: The development of extensive pipeline networks and facilities for storing large volumes of compressed or liquefied hydrogen is essential.
