The year 2019 marked a significant turning point for hydrogen, as breakthroughs in green hydrogen production redefined its global relevance. For decades, hydrogen has been touted as a promising energy carrier, but it is now poised to become a cornerstone of the clean energy transition.
– The key to this transformation lies in the development of affordable electrolysis, a process that splits water into hydrogen and oxygen using renewable electricity.
– Electrolyzers have become cheaper, more efficient, more durable, and scalable for gigawatt projects, unlocking the mass production of clean hydrogen.
Hydrogen’s strengths make it an attractive solution for a range of applications:
– High energy density and compatibility with fuel cells make it ideal for heavy transport and energy storage.
– It can store seasonal renewable energy, providing a reliable and dispatchable source of power.
– Hydrogen can also decarbonize hard-to-abate sectors, such as steel and cement production.
Applications for green hydrogen are vast and varied:
– Shipping and aviation, where hydrogen-electric hybrids are being developed to reduce emissions.
– Long-haul trucking, where hydrogen fuel cell systems offer a promising alternative to diesel.
– Fertilizer production, where green hydrogen can be used to produce ammonia, a critical component of agricultural fertilizers.
– Grid-scale storage, where hydrogen can provide long-duration energy storage and help stabilize the grid.
The legacy of green hydrogen is still being written, but it is clear that it will play a central role in the world’s transition to a low-carbon economy.
– A clean, dispatchable fuel capable of decarbonizing sectors that batteries cannot reach.
– A key enabler of the renewable energy transition, providing energy storage and flexibility.
– A new energy backbone, supporting economic growth and development while reducing greenhouse gas emissions.
