Developing novel carbon dioxide removal solutions for net zero and beyond

What is CarbonLock?

In order to achieve net zero emissions by 2050, we need to dramatically reduce emissions. However, current decarbonisation efforts alone will not get us to net zero. Atmospheric carbon dioxide levels are already too high. We must also directly remove carbon dioxide from the atmosphere.

At CSIRO’s CarbonLock, we’re developing carbon dioxide removal technologies. We’re part of a global effort to remove atmospheric carbon dioxide and lock it up on permanent timescales.

[Image shows a split circle and photos of different CSIRO activities flash through in either side of the circle and then the circle morphs into the CSIRO logo] Narrator: CSIRO is Australia’s national science agency. We solve the greatest challenges through innovative science and technology. [Images move through to show a smoking volcano, cracked dry earth, and a river flooding over a road] The costs of climate change continue to rise. [Images move through to show headlights moving towards the camera, rolling clouds and lightning, and a bushfire burning over a mountain] Australia must move quickly to reach its goal of net zero emissions by 2050. [Images move through of a view looking down on a factory in a city, dirt being squeezed through a male’s hands, and a view of cranes on the roofs of high rise buildings] This requires both decarbonisation and the development of negative emissions technologies to remove atmospheric carbon dioxide. [Images move through of a view looking down on a dry landscape, sea kelp in the ocean, and the sun shining through trees in a forest] Current nature-based methods to do this provide important environmental co-benefits, but we need to go further. [Images move through to show a CSIRO vehicle driving past solar panels, two people walking through a tunnel, a diver swimming amongst fish, a pipette filling test tubes, and two males looking at a 3D visual of wind turbines] CSIRO’s CarbonLock Future Science Platform is addressing this challenge by driving innovation at the nexus of biology, chemistry and engineering to develop new negative emission technologies. [Images move through to show a view looking down on a forest, views of a solar farm, a researcher placing test tubes in a tray, a microchip, and the corridor of a supercomputer] CarbonLock’s research focuses on enabling capture and storage technologies and their integration to deliver permanent carbon removal that is verifiable, fast, scalable, cost-effective and permanent. [Images move through of lights in a city at night, the corridor of a super computer, networking lines over a landscape, and the Investigator ship in the ocean surrounded by networking lines] The CarbonLock FSP brings a multidisciplinary approach to build the foundations of tomorrow’s breakthrough’s in integrated negative emissions technologies. [Images move through of a solar farm, the world globe with joining networking lines over the surface, a supercomputer corridor, and a researcher operating a Smart screen] The future science and capability developed in CarbonLock will underpin new industries and reshape existing industries for Australia to solve the world’s greatest challenge. [Images move through to show a profile and then facing view of a researcher walking towards the camera, and then clouds hanging over the mountain peaks at sunrise, and text appears: research.csiro.au/carbonlock/] For more information about how CSIRO is driving innovation and supporting Australia’s transition to a net zero future, please visit the CarbonLock website.
