At Level Nine, we leverage bio-nanotechnology and quantum chemistry to develop next-generation catalysts to enable the green chemicals of tomorrow. Inspired by nature, our nanozymes bridge the gap between traditional catalysts and enzymes to unlock new possibilities in green chemicals production. Our first nanozymes unlock new ways to cost-effectively convert biomass into renewable chemicals, replacing fossil fuels as the world’s primary chemical feedstock.

At Ucaneo we develop a pioneering Direct Air Capture technology. Ucaneos state-of-the-art electrochemical technology mimics the human lung and how CO2 is managed in the human body. Utilising electricity and a specialised biomimetic solvent, Ucaneo removes atmospheric CO2 at continuous regeneration at room temperature, concentrating CO2 into a pure gas ready for industrial use. The DAC technology is highly energy-efficient and compatible with variable intermittent renewable energy sources such as solar and wind energy, allowing for energy price arbitrage and a flexible, on-demand CO2 removal. Climate change is a global problem and needs to be tackled at scale. Therefore, we set the goal to capture 0.5 GT of CO2 from the air by 2035 - roughly the same weight as all humans on earth combined! After the first promising results we are currently scaling-up our technology. If you want to join an ambitious team with lots of freedom and growth check out our career page. We are looking for talents in the area of chemical engineering, electrochemistry and mechanical engineering and cannot wait to meet you!

Nuventura develops environmentally-friendly medium voltage (MV) gas insulated switchgear (GIS) – key hardware components found throughout electrical grids and energy infrastructure. Our patented technology replaces Sulphur hexafluoride (SF6) – the world’s strongest greenhouse gas – with dry air, whilst maintaining GIS traditional strengths i.e. compact physical dimensions. Such alternatives are urgently needed because, in the coming years, regulators are expected to phase out SF6’s use in switchgear due to its high environmental impact. Nuventura works with both switchgear end-users (utilities, EPCs, industry, project developers etc.) and manufacturers (OEMs, panel builders) with the aim of accelerating and facilitating the energy industry’s transition away from SF6. In so doing, nuventura helps companies reduce their carbon footprint and become compliant with imminent international regulation focused on the use of SF6 in switchgear.
