Abstract: In order to limit global warming and avoid the most disastrous effects of climate change, we need to (1) drastically reduce emissions and (2) remove large amounts of legacy greenhouse gases from the atmosphere. There are many approaches to CDR (carbon dioxide removal), the process to remove carbon dioxide from the atmosphere and locking it away for decades, centuries and millennia: from planting new forests, capturing and sequestering carbon from waste biomass, spreading crushed rock on agricultural fields to react with CO2 in rainwater, building chemical adsorption-looping processes or enhancing the oceans ability to store carbon dioxide. In this talk we’ll have a look at specific benefits and challenges across CDR technologies. We will explore considerations of durability, verifiability, and scalability and discuss how a balanced portfolio of solutions can maximize climate value.
Bio: Dr Frauke Kracke is a biochemical engineer by training who has always been fascinated with the intersection of technology and nature. She spent her academic career across Germany, Australia and the US including 5 years at Stanford looking at processes that integrate electrochemistry and microbiology, enabling the production of chemicals and fuels from CO2, water and clean electrons. In 2022, Frauke joined Frontier, a >$1B advance market commitment to advance solutions for permanent removal of atmospheric CO2. In her position as science lead, she lays the scientific groundwork to evaluate a diverse portfolio of carbon removal technologies to identify and advance the most promising ones.
