ナノテクノロジーは気候変動の解決に役立つか?(Can Nanotechnology Help Solve Climate Change?)

2024-10-09 米国国立標準技術研究所(NIST)

NISTの科学者ジェームズ・ウォーレンとクレイグ・ブラウンは、ナノテクノロジーが気候変動対策に貢献できると主張し、特にエネルギー効率やカーボンキャプチャーの分野での応用を強調しています。ナノ触媒を使えばグリーン水素の生産コストを削減でき、ナノサイズのフィルターはCO2を効率的に吸収します。また、ナノコーティングを施した窓は建物のエネルギー消費を最大40%削減できる可能性があります。これらの技術は、気候危機に対応するための重要なツールとして注目されています。

ナノテクノロジーは気候変動の解決に役立つか?(Can Nanotechnology Help Solve Climate Change?)

Climate change is one of humankind’s biggest challenges, leading to more frequent and intense climate extremes, including heatwaves, wildfires, hurricanes, ocean acidification, and increased extinction rates. Nanotechnology already plays an important role in decarbonizing critical processes. Still, despite the technical advances seen in the last decades, the International Energy Agency has identified many sectors that are not on track to achieve the global climate mitigation goals by 2030. Here, a multi-stakeholder group of nanoscientists from the public, private, and philanthropic sectors discuss four high-potential application spaces where nanotechnologies could accelerate progress: batteries and energy storage; catalysis; coatings, lubricants, membranes, and other interface technology; and capture of greenhouse gases. This Comment highlights opportunities and current gaps for those working to minimize the climate crisis and provides a framework for the nanotechnology community to answer the call to action on this global issue.
