Atmospheric Methane Removal

The Methane Removal Platform

The methane removal Platform

Adding ISA into the atmosphere is possible in different ways. One way to produce ISA is to heat it up and let it be lifted in the plume of a stack. Actually, man adds ISA into the air since the industrial revolution. Steelworks and coalpits release Fe2O3 which forms into ISA. All of this happens every day, it is nothing new. Pollution has, in this case, a beneficial aspect. But nobody ever knew this in the past centuries.

How much ISA do we have to put into the atmosphere? To answer that, Restore Our Climate currently runs experiments, so called smog-chamber tests. They simulate the process and when they are finished, we can tell you. But we already know: It will be hundreds of thousands of tons per year.

That is a lot. But then again, it is very little. When you consider the fact that 596 million tons of methane are released into the air each year (7) – 100,000 tons is like a grain of salt in the soup.

AMR aims to emulate the industrial process which brings ISA into the air. However, unlike in ‘beneficial pollution’ which does this accidentally, we want to control this process from beginning to end. We want to build an ISA disperser and put it on an oil-rig, where the wind will disperse the ISA over a large region of the ocean. The rig will have the specific purpose to disperse ISA in the atmosphere, hence we call it a methane removal platform (MRP).

One very visible element of an MRP is the high tower with a pipe which will transport ISA to hundreds of meters above sea level. Oil-rigs feature lattice steel towers, so-called derricks, for the purpose of oil-drilling. We will use the existing derrick or replace it with a lighter, higher tower.

We estimate that 20 MRPs will be needed to remove half of all methane (1 ppm) from the atmosphere. Each MRP will bring around 15.000 tons of iron per year into the air, so all in all it will be tons. Our plan is to use decommissioned, semi-submersible oil-rigs for the purpose of dispersion. These rigs can be towed to the best locations and anchored even in deep sea. Hundreds of rigs will be available when oil-drilling is phased out.
