Abstract
Abstract ‘Other low-carbon technologies’ examines other low-carbon technologies, and sees how they fare against those already discussed in previous chapters. These are the renewables: tidal, wave, and geothermal power; and the low-carbon technologies of nuclear power and carbon capture. The contribution from tidal and wave power is small, with only a few tidal stream and underwater wave devices under development, and that the power from geothermal sources is potentially large, but difficult to extract. The deployment of nuclear power has been affected by concerns over its safety, the disposal of its waste, and its cost. By 2050, the total generation from all renewables and nuclear power could be close to 90 per cent of current global demand. While capture at fossil-fuel power plants looks uncompetitive, air capture through reforestation and through using chemical absorbers might remove 10 per cent of the emissions of carbon dioxide and help the world to be on target to achieve net-zero emissions.
