Emerald Hydrogen from Wastewater

The Emerald Option

Ammonia is a naturally occurring element that is produced abundantly by both livestock and humans. As ammonia has many industrial uses, it is also produced industrially to the tune of more than 200 million tonnes a year; this with a massive energy input and a concomitantly enormous carbon footprint.

Large quantities of ammonia are entrained in wastewater and, if it is not adequately treated, its uncontrolled emission to waterways can result in the oxygen depletion of rivers together with all the deleterious effects that this has on wildlife, both flora and fauna.

But what if there was a way to capture the ammonia that is entrained in wastewater? Is there a way that it can be reused and displace the necessity for generating industrially produced ammonia?

The answer is the emerald option.

Ammonia Recovery

Ammonia capture and recovery was first pioneered by the ORGANICS GROUP in Hong Kong. Leachate with high levels of ammonia is treated using heat in a SMART flare. The first plants were for removal and destruction of ammonia. Now interest in recovering the ammonia has increased and several projects are underway to use the ammonia, not only for use as a fertilizer but also for recovering hydrogen.

With more than 300 projects related to the control of emissions, the Organics Group is well placed to offer bespoke services in all aspects of project development, from inception to completion and delivery.

Fuels for the Future

Recovering ammonia from wastewater is an additional step in the treatment of wastewater. This step results in a more thorough treatment of the wastewater, and also in the recovery of elements that can be usefully employed. Once recovered, ammonia can be safely transported to the point use and either be used directly as a fuel or be subjected to further treatment (cracking) to produce hydrogen. This not only reduces operational costs, increases bottom-line profit but also contributes towards the movement towards the circular economy.
