Sanchez, Daniel L.; et al. (2018): Near-term deployment of carbon capture and sequestration from biorefineries in the United States

Sanchez, Daniel L.; Johnson, Nils; McCoy, Sean T.; Turner, Peter A.; Mach, Katharine J. (2018): Near-term deployment of carbon capture and sequestration from biorefineries in the United States. In Proceedings of the National Academy of Sciences of the United States of America. DOI: 10.1073/pnas.1719695115.

"Here, we evaluate low-cost, commercially ready CO2 capture opportunities for existing ethanol biorefineries in the United States. The analysis combines process engineering, spatial optimization, and lifecycle assessment to consider the technical, economic, and institutional feasibility of near-term carbon capture and sequestration (CCS). Our modeling framework evaluates least cost source–sink relationships and aggregation opportunities for pipeline transport, which can cost-effectively transport small CO2 volumes to suitable sequestration sites; 216 existing US biorefineries emit 45 Mt CO2 annually from fermentation, of which 60% could be captured and compressed for pipeline transport for under $25/tCO2."

Futurity: Carbon capture could pay off for biofuel plants

"The researchers estimate that 60 percent of all CO2 emitted annually through the production of ethanol at the country’s 216 biofuel plants (about 1 percent of all CO2 emissions from the US) could be captured at low cost, under $25 per metric ton of CO2."

The Daily Beast: Here’s One Way to Combat Climate Change: Suck Out Carbon Dioxide

“We have to be careful with this approach because it can tempt people to keep burning fossil fuels,” Wilcox said. “It can’t be seen as a silver bullet. It has to be one part of multiple options.”

Technology Review: The daunting math of climate change means we’ll need carbon capture

"Amid this daunting climate math, many researchers argue that capturing carbon dioxide from power plants, factories, and the air will have to play a big part in any realistic efforts to limit the dangers of global warming."

phys.org: Carbon capture could be a financial opportunity for US biofuels

"There's really no scenario that meets the world's climate goals without negative emissions," said Katharine Mach, a senior research scientist at Stanford's School of Earth, Energy and Environmental Sciences. "But most technologies for carbon removal are immature, largely unavailable or expensive."

Job: UCS Fellow: Geoengineering Governance and Public Engagement

Deadline: 03. June 2018

"As Fellow, you will identify and develop research to inform the emerging discussion on solar geoengineering within US and international NGO, scientific and policy communities. Your work will inform UCS-supported guidelines for whether and under what conditions solar geoengineering field experiments should move forward. Research is expected to include a focus on the roles and responsibilities of researchers, funders and policymakers to ensure that field experiments are subject to meaningful societal input and informed consent. This full-time position is funded through September 2019, with a possibility of extension."
