Sydney Sustainable Carbon
Carbon dioxide is essential to life on the face of our planet. Plants and algae, for example, require carbon dioxide for photosynthesis, converting these molecules into oxygen and carbohydrates for growth.
The natural carbon cycle has been in balance for hundreds of millions of years. However since the industrial era, the carbon dioxide concentration in our atmosphere has risen dramatically, enhancing the greenhouse effect that has led to additional warming of our atmosphere. It is this change in our climate as a result of excess carbon dioxide (as the major contributor amongst the greenhouse gases) that is now threatening the delicate balance required by ecosystems on our planet.
The 2015 Paris Agreement sought to unite countries in the fight against climate change by devising strategies to keep the global temperature rise to a maximum of 1.5 °C. While a significant focus is on emissions reductions, the Intergovernmental Panel on Climate Change (IPCC) says this will not be enough to avoid dangerous levels of global warming: the world must actively remove historical carbon dioxide (CO₂) already in the atmosphere through processes often described as Negative Emissions Technologies (NETs).
In partnership with Australian renewables start-up Southern Green Gas (SGG), Sydney Sustainable Carbon has a bold vision: to sustainably source carbon dioxide from the atmosphere. The captured gas can either be compressed and stored (via geosequestration, leading to NET), or can be utilised (via Carbontech). Our DAC technology is based on Metal-Organic Frameworks (MOFs) for highly selective carbon dioxide removal from air. We are developing high volume continuous flow synthesis of these materials coupled with innovative 3D printing methods to produce ultra-high surface area DAC capture modules. SGG's modular system is fully powered by renewable solar energy and can sustainably scale to reach gigatonne carbon dioxide removal.
Our project is also supported by the Musk Foundation's XPRIZE student prize (2021-24). See the press release here.

CO-BENEFITS, SOCIAL LICENCE TO OPERATE & ENVIRONMENTAL JUSTICE
In partnership with Southern Green Gas (SGG), Swiss Re and Corporate Carbon Advisory, we are committed to helping the community, governments and other stakeholders understand the potential impacts and implications of DAC technology, and to co-design solutions to these concerns.
There are many co-benefits to DAC technology including:
We are strongly engaged in developing interdisciplinary collaborations across the University of Sydney campus to help build social license to operate for DAC technology. Our current collaborators include:
There have also been concerns stated for DAC technology. We briefly address these here and encourage you to reach out to us for discussion at any time.
