Negative Emissions Technologies

Active removal of carbon from the atmosphere at gigaton scale is a requirement for climate mitigation strategies in the later part of the 21^st century. This is a very grand challenge and an X-Prize in this area was recently announced by Elon Musk- https://www.xprize.org/prizes/elonmusk.

We have an active program of research into both terrestrial NET technologies using modified biomass, for secure storage in a variety of settings (AVECS), and also a program of large scale ocean carbon cycle options for carbon management and a prototype concept for carbon removal (PEACH).

There have been many significant proposals and discussions on geochemical routes and technologies to ocean air capture of CO₂ at scale e.g.: 

• Kheshgi, H.S., 1995. Sequestering atmospheric carbon dioxide by increasing ocean alkalinity. Energy, 20(9), pp.915-922.
• Renforth, P., Jenkins, B.G. and Kruger, T., 2013. Engineering challenges of ocean liming. Energy, 60, pp.442-452.
• Rau, G. H. "Electrochemical formation of hydroxide for enhancing carbon dioxide and acid gas uptake by a solution." U.S. Patent 8,177,946, issued May 15, 2012.

With inspiring and practical concepts appearing such as the Planetary Hydrogen concept (https://www.planetaryhydrogen.com/) of accelerated rock weathering linked to hydrogen production. We too seek benign and scalable routes to very large scale CO₂ capture based on the Ocean carbon cycle.

We are part of the A.M Hubert led geoengineering governance initiative.
