Saudi Arabia Wants to Freeze Carbon to Cut Emissions From Power

  • University hopes the technology can be used across kingdom
  • Cryogenics could cut carbon capture costs in half, says KAUST

Scientists in Saudi Arabia are testing a new idea for trying to slow climate change: freezing greenhouse-gas emissions from power plants.

A team at a university on the Red Sea coast is trying out a technique for cooling carbon dioxide when fossil fuels are combusted to produce electricity. Once in a solid or ‘dry ice’ form, the pollutant can be stowed underground or used to make chemicals and other products. At least that’s the theory.
