Video: How to turn emissions into products (DW Planet A)

„Some companies are trying to make a carbon difference by manufacturing products made out of pollution. But is it really helping? What’s behind the fancy technology, and how does this bode for the planet’s—and consumer’s—future? We’re destroying our environment at an alarming rate. But it doesn’t need to be this way. Our new channel Planet A explores the shift towards an eco-friendly world — and challenges our ideas about what dealing with climate change means. We look at the big and the small: What we can do and how the system needs to change. Every Friday we’ll take a truly global look at how to get us out of this mess.“


Bennett, Jeffrey A.; et al. (2021): Life cycle meta-analysis of carbon capture pathways in power plants: Implications for bioenergy with carbon capture and storage

Bennett, Jeffrey A.; Abotalib, Mohammad; Zhao, Fu; Clarens, Andres F. (2021): Life cycle meta-analysis of carbon capture pathways in power plants: Implications for bioenergy with carbon capture and storage. In International Journal of Greenhouse Gas Control 111, p. 103468. DOI: 10.1016/j.ijggc.2021.103468.

„Bioenergy with carbon capture and storage (BECCS) based electricity generation is one possible approach for delivering large-scale carbon dioxide removal from the atmosphere. This study evaluates the environmental impacts of leveraging existing power plants for BECCS. We performed a life cycle meta-analysis of eight carbon capture technologies, including five previously simulated only for coal and natural gas, for both steam cycle and integrated gasification combined cycle (IGCC) power plants. We found that IGCC plants offer the best balance of negative emissions, energy return on investment (EROI) and low water use irrespective of capture technologies. Planned IGCC plants tend to be large whereas biomass-fired power plants are often small and distributed in the landscape because of the distributed nature of the fuel. Steam cycle plants had larger negative emissions, but also lower EROI, and so blending with coal may be necessary to achieve a suitable EROI. Steam cycles were sensitive to capture technology type, and results found membrane and calcium looping capture technologies offer a balance between negative emissions, EROI and water use when fired using coal-biomass blends. These results suggest that steam cycle power plants may be the most desirable candidates to support early-stage deployment of BECCS.“


Podcast: Carbon Removal Newsroom: Climate Week NYC: a market for carbon removal, as told by buyers and sellers

„In this special bonus episode of Carbon Removal Newsroom, we’re bringing you a panel from this week at Climate Week NYC that covers the state of the carbon removal market, as told by today’s buyers and sellers. The panel is hosted by CarbonCure technologies and is moderated by Peter Minor, Director of Science and Innovation at Carbon180. Panelists include: Robert Niven, CarbonCure Technologies Chair [&] CEO Stacy Kauk, Shopify Sustainability Fund Director Mischa Repmann, Swiss Re Senior Environmental Management Specialist [&] Marcius Extavour, XPRIZE Vice President of Energy [&] Climate Listen in for a comprehensive assessment of the current state of the carbon removal market, and to hear goals and predictions for the future of the industry. The panelists discuss the pace of innovation, market making, carbon removal as a de-risking mechanism, and the role that government should play in scaling up the market. Then, the panelists answer an assortment of audience questions during the last 30 minutes of the event.“
