NanobOx raises €900k to revolutionise agriculture and acquaculture

Irish business NanobOx’s novel nanobubble technology dissolves gases in water using a fraction of the energy consumed by conventional methods.

Irish start-up NanobOx has secured first-round funding of €900,000 from a consortium of Irish venture capital investors.

The lead investor is The Yield Lab, with the remainder coming from DeepIE Ventures and Growing Capital. This funding will see the company complete field trials in agriculture and aquaculture, with the aim of going to market in 2024.

“It requires less energy than it takes to power a lightbulb, in contrast with competing methods of nanobubble production that consume hundreds of watts of power”

A spin-out from University College Dublin (UCD), NanobOx has developed novel, patented technology that adds gases such as oxygen, ozone and carbon dioxide to water using nanobubbles.

Industrial breakthrough

Bubbles are used in a wide range of industries to dissolve gases in water. The smaller the bubbles, the better they are at transferring the gas to the water – but the more expensive they are to generate.

“Our revolutionary nanobubble technology generates nanobubbles using a low-voltage electric field that has no moving parts,” explained Dr John Favier, CEO and co-founder of NanobOx with Trinity College Dublin engineering professor, Dr Mohammad Reza Ghaani, who developed the technology while at UCD.

“It requires less energy than it takes to power a lightbulb, in contrast with competing methods of nanobubble production that consume hundreds of watts of power.”

A particular focus for NanobOx is using its technology to add oxygen to water using only ambient air.

“We uniquely generate nanobubbles from air that are enriched with oxygen, providing an oxygen-transfer efficiency of 90%, compared to less than 20% using conventional aeration,” noted Dr Favier.

“Our first-generation products are being designed under exclusive licence from UCD for use in agriculture and aquaculture to increase crop yield and reduce input costs. Nanobubbles carry nutrients and oxygen in irrigation water to plant roots, accelerating crop growth and reducing the amount of fertiliser needed.”

In aquaculture, NanobOx aims to radically cut the cost of oxygenation, as well as enhancing fish health and boosting growth rate, he continued. “NanobOx technology can be deployed to significantly reduce energy costs and enhance performance in any bioprocess requiring addition of oxygen to process water, including wastewater treatment, industrial bioreactors and environmental remediation.”

Field trials of the novel nanobubble aeration technology are under way with multinational fruit and vegetable producers Dole plc, Dutch horticulture experts Delphy, and Irish nutraceutical and ornamental plant specialists Beotanics and Fitzgerald Nurseries. Ireland’s Goatsbridge Trout Farm and Connemara Abalone shellfish farm will investigate how the aquaculture sector can maximise benefits of the technology.

NanobOx was the winner of Enterprise Ireland’s Big Ideas ‘One to Watch’ award in 2022. It has been recognised by Bord na Móna in its Accelerate Green programme, as one of a cohort of early-stage companies in Ireland bringing innovative sustainable technologies to the market, with potential to have a major impact globally.
