Project Summary / Description:
We began this business because the need for robust carbon removal solutions is now abundantly clear ‚ the UN‚ Intergovernmental Panel on Climate Change has shown that around 6 billion tonnes of carbon dioxide will have to be removed from the atmosphere each year by 2050. Irrespective of how quickly we decarbonise the global economy (our work is not an attempt to replace economy-wide decarbonisation), carbon removal will be needed to avoid the worst impacts of climate change. The project was started when Maurice, who has a background in agriculture, approached Professor Frank McDermott, who is a low-temperature geochemist to undertake some fields trials on returned concrete as an enhanced weathering solution.

How Project Affects Greenhouse Gas (GHG) Emissions:
Removes/stores GHGs (e.g., projects that capture, sequester, or otherwise enhance the "sinks" that accumulate and store GHGs)
Best Estimate of GHG Avoidance/Reduction of This Project (Tonnes CO2 Equivalent/Year):
Impact on Underrepresented Groups:
We are currently about to hire two women to join our team. Their domain expertise is second to none, and we are excited for them to join the team. We are also hiring young people to help with our scientific work.

Measurement, Reporting & Validation
Silicate is a carbon removal company leveraging the power of geochemistry to permanently remove carbon dioxide from the atmosphere. Our core technology is the ability to remove excess carbon dioxide from the atmosphere via the acceleration of a natural geological process ‚ the weathering of silicate and hydroxide minerals. Our material is derived from returned concrete, which is processed and spread on agricultural land as a soil pH amendment, much like traditional ground limestone. Silicate is the first company in the world to utilize this abundant material (2-5% of all concrete produced is returned) to sequester carbon at scale, and we have developed robust in-situ measurement and modelling capabilities to verify the rates of carbon removal we enable. We are primarily operating in Ireland, with plans to expand to Germany and the US in 2023.
