I’ve Just Come Across Avnos

I feel we should take into account any possibilities of second use of oil or gas structures, that once held hydrocarbons.

An article in a magazine called Carbon Herald pointed me to a company called Avnos, who are developing Direct Air Capture of carbon dioxide out of the atmosphere. If systems like that of Avnos do work, we may need somewhere to put the carbon dioxide.

Centrica are storing the hydrogen in the Rough gas field, which was previously used for storing natural gas and now some depleted gas fields are being used to store captured carbon dioxide.

On the subject of carbon capture, Avnos do it differently, in that for every tonne of CO2, they capture from the air, they capture five tonnes of distilled water. And they do it without using any heat.

This is their web site.

This is their mission statement on the front page of the web site. There is also a video.

Carbon Negative. Water Positive

Avnos is commercializing the most advanced technology in the Direct Air Capture of CO₂

Our proprietary Hybrid Direct Air Capture (HDAC) solution inverts the water paradigm in DAC, producing water, eliminating heat consumption and reducing costs compared to other forms of DAC.

It sounds too good to be true!

But I have experience of the positive financial results of fluid dynamics in this area.

Thirty years ago, two guys approached me with an idea for an aerosol valve that used nitrogen as a propellant.

At the time, I lived in the house, where Osborne Reynolds, the great Victorian fluid dynamicist of Reynold’s number fame had been brought up.

The guys succeeded and the device was sold on to J & J.

They were then asked to develop a metered dose inhaler for asthma drugs, which is now sold as Respimat, which is sold by Boehringer Ingelheim.

Afterwards, I researched Reynolds at Manchester University, where he was the first Professor of Engineering and I found that he had done some marvelous things with fluids. He was a true genius and undergraduates are still taught on his Victorian apparatus.

I suspect that Avnos may have been exploring in the same area and are using another of Reynold’s useful properties.
