Green ammonia produced using solar renewable energy offers a sustainable and environmentally friendly alternative to conventional ammonia production. By utilising high-temperature electrolysis powered by solar energy, pressurised hydrogen can be generated directly, eliminating the energy-intensive compressor stage traditionally required before the Haber-Bosch process. This not only reduces the overall energy consumption and operational costs but also enhances the efficiency of green ammonia synthesis.

Revolutionising clean fuel — solar to ammonia, affordable, scalable, and sustainable

Green ammonia produced using solar renewable energy offers a sustainable and environmentally friendly alternative to conventional ammonia production. By utilising high-temperature electrolysis powered by solar energy, pressurised hydrogen can be generated directly, eliminating the energy-intensive compressor stage traditionally required before the Haber-Bosch process. This not only reduces the overall energy consumption and operational costs but also enhances the efficiency of green ammonia synthesis.

Green ammonia holds significant potential as a sustainable fuel for the marine and aviation sectors, two of the hardest-to-decarbonize industries. As a carbon-free energy carrier produced from renewable electricity and nitrogen, green ammonia can be used directly in combustion engines or cracked into hydrogen for fuel cells, offering flexibility and lower emissions.

In maritime shipping, ammonia’s high energy density and existing global infrastructure make it a promising alternative to heavy fuel oil. For aviation, while direct use may require new engine designs or fuel-cell adaptation, green ammonia’s role as a hydrogen carrier opens pathways to sustainable aviation fuels. With ongoing advances in technology and regulatory support, green ammonia could become a cornerstone of clean, long-distance transport.
