Australian hydrogen developer Hiringa Energy has received US-made solar power technology that will help supply renewable energy to its low-carbon cotton project in New South Wales. Once installed the new tech should boost the efficiency of green hydrogen production.

The technology, supplied by Ampt, uses string optimisers to improve solar power systems. These small electronic devices control the output of each solar panel and allow the overall system to perform at its best, even if some panels are shaded or underperforming.

By improving power delivery from the solar farm, Ampt’s technology enables Hiringa’s GEGHA project to more efficiently generate green hydrogen and ammonia – the core ingredients of a low-carbon fertiliser being used on the farm’s cotton crops.

The GEGHA project aims to make agricultural production more sustainable by producing fertiliser and hydrogen through a combination of solar power, battery storage, electrolysis, and ammonia synthesis.
