Medium, device and method for monitoring reporting and verification of carbon dioxide removal

A device (1) for monitoring, reporting and verification of carbon dioxide removal in enhanced rock weathering, the device (1) comprising three chambers (2, 3, 4), the chambers being a first chamber (2), an intermediate chamber (3) and a second chamber (4), wherein the intermediate chamber (3) is present between the first chamber (2) and the second chamber (4)

• the first chamber (2) and the second chamber (4) house soil and the intermediate chamber (3) houses a medium (7) for adsorbing and storing bicarbonate ions,
• the first chamber (2) and second chamber (4) are separated from the intermediate chamber (3) by porous layers (5, 6), and
• the porous layers (5, 6) are configured to prevent the movement of soil from the first chamber (2) and second chamber (4) into the intermediate chamber (3) while allowing the soil infiltrate to pass through the chambers (2, 3, 4) of device (1), and
• wherein
• the medium (7) for adsorbing and storing bicarbonate ions comprises an anion exchange resin and beads of a rigid, inert, non-porous material in a pre-determined mass ratio.
