Reactor-based enhanced rock weathering system with measurement, reporting and verification for Carbon Capture and Storage

Objetivo

The escalating global emissions of greenhouse gases threaten our planet's foundation. Atmospheric CO2 levels have reached more than 420 ppm, with an annual increase of more than 2 ppm; we are already witnessing the catastrophic effects on ecosystems, economies, and human societies worldwide. The main challenge for CO2-emitting industries is complying with the EU Emissions Trading System (EU ETS) and thus, quickly deploying cost-effective solutions that will ensure this compliance.
Planeteers has developed an innovative solution, to store CO2, that mimics the natural weathering of limestone but accelerates it from thousands of years to just a few minutes using the same natural ingredients. CO2 from biogenic or fossil point sources is dissolved in water through our scrubber and mixed with a limestone (CaCO3) solution in our alkalinity reactor. During the reaction, CO2 is converted into bicarbonate (HCO3-) and stored in the water. After equilibration with the atmosphere and the local aquatic environment in our diffuser system, it can be released in a controlled way to water bodies which transport the mineralized water to the ocean. There, the CO2 is stored as bicarbonate on a long-term basis (10,000-100,000 years) helping at the same time to reduce the
water acidification locally. The Compliance carbon market (CCM) is our target for entry supported by the EIC Accelerator. The REACT CARBON project lays the foundation for our expansion into the CCM, emphasising its strategic importance. We will focus initially on cement and limestone industries emissions: they currently emit around 160 million tons of CO2. Considering the EU Fit-for-55 reduction targets and CCS prices increasing to €146 per ton, Planeteers market value in the EU is conservatively estimated to be at least €2.0 billion.
