The UK’s Department for Environment, Food and Rural Affairs (Defra) has recently released a 95-page report stating that nanotechnology might offer hope for climate change. This study has focused on 5 specific areas: fuel additives, solar cells, the hydrogen economy, batteries and insulation. The conclusion of this report is that nanotechnology could contribute to reduce greenhouse gas emissions by up to 20 per cent by 2050. The largest reduction would come from using hydrogen as a source of energy. Unfortunately, this might be very difficult and will take years.
Can nanotechnology be good for climate?
