SpiralWave has developed pulsing plasma towers that can capture carbon dioxide from the atmosphere or smokestacks and convert it into useful fuel.
The plasma waves, ignited by different pulses of microwaves, break down CO2 into CO, H2O into H and OH, and then join them to form methanol.
SpiralWave's process transforms 75-90% of electrical energy into methanol, making it more efficient than other methods.
The company plans to scale up its devices to remove gigatons of CO2 annually and is focused on replicating smaller devices to be installed at customer sites.
