Rockit (winner)
The “Rockit” technology from Heriot-Watt University prevents undesired leaks of greenhouse gases (methane, CO2), flammables, toxins, carcinogens (hydrocarbon gas, H2S, mercury vapour), and stored gases (hydrogen, CO2) from escaping through drilled wells to the atmosphere. It seals potential leak paths and fractures around the borehole of a well within the rock itself with an impermeable mineral barrier that is resistant to aggressive acidic conditions downhole. No flow from surrounding rock formation to the wellbore is possible, cement plugs are protected from degradation and therefore fluids (gases, oil, contaminated water) are locked deep underground for many thousands of years.
