Impossible Metals‘ (YC W22, Public Benefit Corporation) vision is to accelerate clean energy by delivering sustainable critical metals. We are developing autonomous underwater vehicles (AUV) to harvest critical metals from the seabed while protecting the environment. We are also working to replace the often dangerous and unsustainable metal refining process using novel bacterial respiration technology, which does not use hydrometallurgy (huge energy) or pyrometallurgy (acid tailings). These two innovations, sustainable harvesting and biological refinement, can support our global ability to develop green technology and responsible electric vehicles. Located in the US and Canada, Impossible Metals is committed to the UN Sustainable Development Goals.
