May 17, 2007 — The U.K. Department for Environment, Food, and Rural Affairs (DEFRA) has published the results of a study that explored how nanotechnologies could cut the use of non-renewable energy sources and reduce greenhouse gas emissions. The study investigated the opportunities and potential obstacles to adoption of a number of environmentally beneficial nanotechnologies.

The resulting report,
Environmentally Beneficial Nanotechnologies: Barriers and Opportunities, discusses the application of nanoscience in the areas of insulation, photovoltaics, electricity storage, engine efficiency and the hydrogen economy.

DEFRA’s Chief Scientific Adviser, Howard Dalton, said the report “indicates the key areas where nanoscience may help lessen its effects and contribute to achieving society’s ambitions for a sustainable future. However, the report draws particular attention to the need for government, industry and scientific communities to work together in answering some of the fundamental questions regarding the behaviour and toxicity of nanomaterials”.

According to DEFRA Minister Lord Rooker, “Government is considering the report’s recommendations for further research and action to foster progress and bring about the adoption of some exciting new technologies.”

The study investigated five nanotechnology applications: fuel additives, photovoltaics (solar cells), the hydrogen economy, electricity storage, and insulation.
