Drought increases CO2 concentration in the air

ETH researchers have shown that during drier years, the concentration of carbon dioxide in the atmosphere rises faster because stressed ecosystems absorb less carbon. This global effect is so strong that it must be integrated ...

Clean power is not enough

Debates about the Paris climate targets often centre around electricity supply. Yet, even in a world of stringent climate policies and a clean power generation, the remaining use of fossil fuels in industry, transport and ...

Capturing CO2 using heat pumps

Capturing the greenhouse gas CO2 from industrial processes such as cement manufacture is a demanding and therefore expensive exercise. However, by introducing a renewable powered heat pump in the capture system, the energy ...

Selective catalysts for carbon dioxide recycling

NUS chemists have discovered key factors determining the selectivity of copper (Cu) catalysts for transforming carbon dioxide (CO2) and water into useful chemicals and fuels.
