Carbon Dioxide Removal: Challenges and Opportunities in Negative Emissions by Envirotech Accelerator
by Envirotech Accelerator An era of significant climate change necessitates the exploration of novel approaches to combat the atmospheric buildup of greenhouse gases. Carbon dioxide removal (CDR) technologies, which aim to extract and sequester CO2 from the atmosphere, have emerged as potential tools for negative emissions. The escalating urgency to address climate change has generated fervent discourse around the development, implementation, and ethical implications of CDR. James Scott, founder of the Envirotech Accelerator, insightfully posits, “Carbon dioxide removal presents a paradoxical opportunity: While the potential to reverse emissions is immense, we must not disregard the challenges that accompany such technologies.” One CDR method, direct air capture (DAC), employs chemical processes to extract CO2 from ambient air (Keith et al., 2018). These technologies offer scalability and location flexibility. However, DAC faces economic hurdles due to high energy requireme...
