Green Gold Hydrogen2 Ltd

Green Gold Hydrogen 2 (GGH2) is a specialist engineering and consultancy firm that focuses on the development of clean‑energy fuels and the up‑cycling of plastic waste. Drawing on patented microwave‑catalyst technology, the company converts plastic feedstock into low‑pressure green hydrogen and ultra‑pure single‑wall carbon nanotube (SWCNT) powder in a rapid, 90‑second process that can handle up to 500 kg of material per run.

The core services offered by GGH2 include project management, technical consultation and engineering design for first, second and third‑generation fuels and biofuels in liquid, solid and gaseous forms. Their flagship product – 99.7 % pure SWCNT powder – boasts exceptional mechanical, electrical and thermal properties, making it highly sought after for nano‑electronics, advanced composites and a range of cutting‑edge material applications. In parallel, the generated green hydrogen provides a sustainable energy carrier for manufacturers seeking low‑carbon solutions.

Headquartered in Dublin, Ireland, GGH2 serves clients across the island and internationally, leveraging its patented processes to help businesses transition to cleaner energy and more circular waste‑management practices.
