Ouros – Why We Invested
One focus of Tranquillion’s venture investments is pathways enabling 800+Wh/kg battery densities. These levels enable electric aviation, maritime electrification, and transformational automotive and long-duration grid storage, all necessary to achieve step change decarbonization. Tranquillion is proud to invest in Ouros’ Series A to enable this goal.
Ocean Health & Microplastic Pollution: Partnership with Dimitri Deheyn
At Tranquillion, we seek opportunities that bridge disciplines, translate knowledge into action, and advance the systems change required to improve outcomes for people and the planet. Climate change, biodiversity loss, pollution, and human health are still too often studied, addressed, and funded in isolation. We are drawn to partners working at the confluence of these challenges and this is what drew us to Dr. Dimitri Deheyn and his team at the Scripps Institution of Oceanography.
