New system creates bioplastics, consumes CO2

Read the full story from Washington University in St. Louis.

A team of researchers has developed a system that uses carbon dioxide, CO2, to produce biodegradable plastics, or bioplastics, that could replace the nondegradable plastics used today. The research addresses two challenges: the accumulation of nondegradable plastics and the remediation of greenhouse gas emissions. The work was published in the Sept. 28 edition of the journal Chem.

A novel coordination polymer-based photocatalyst for CO2 reduction exhibits unprecedented performance, giving scientists new hope in the fight against global warming. Made from abundant elements and requiring no complex post-synthesis treatment or modifications, this promising photocatalyst could pave the way for a new class of photocatalysts for efficiently converting CO2 into useful chemicals.

Carbon Dioxide Removal Technology Roadmap: Innovation Gaps and Landscape Analysis

Download the document.

This Innovation Roadmap presents an overview of the current status, innovation needs, and research efforts in Mission Innovation (MI) Carbon Dioxide Removal (CDR) Mission member countries for three CDR approaches: direct air capture with storage, enhanced mineralization, and biomass with carbon removal and storage.

The Roadmap was authored by members of the CDR Mission. It draws on a review of recent literature, a survey of CDR Mission members, and input from mission stakeholders and subject matter experts. Innovation needs and other potential opportunities compiled by the authors are intended for consideration and discussion by CDR Mission members. The document is designed to assist and inform members in identifying opportunities for collaboration that accelerates research, development, and demonstration (RD&D)—and ultimately for accelerating responsible large-scale deployment—of CDR technologies. References are provided throughout the Roadmap for readers to explore topics in further depth.

CDR Mission members are concurrently developing an Action Plan that builds on this Roadmap to articulate specific activities to be led by mission members that address priority innovation needs in the near-, mid-, and long-term. The Roadmap concentrates on technical challenges, needs, and efforts. Non-technical challenges are introduced in the document and CDR Mission members recognize their critical importance for CDR deployment, but they are not the focus of this Roadmap.

The Roadmap focuses primarily on technologies and systems for the ‘atmospheric carbon dioxide (CO2) capture’ portion of engineered and hybrid CDR approaches. Technology challenges and innovation gaps associated with CO2 transport, storage, and use in products are essential aspects of CDR systems but are not covered in depth in this document. Carbon dioxide transport, storage, and use are examined by other international fora such as the Technical Group of the Carbon Sequestration Leadership
Forum (CSLF) and the IEA Greenhouse Gas R&D Programme (IEAGHG).

The CDR space is rapidly evolving. The Roadmap provides a snapshot given current understanding and circumstances. CDR Mission members will continue to monitor the progress of relevant technology development and adjust priorities commensurate with changing needs.

Analysis of alternative bioenergy with carbon capture strategies: present and future

Geissler, C.H. and Maravelias, C.T. (2022). “Analysis of alternative bioenergy with carbon capture strategies: present and future.” Energy & Environmental Science 5, 2679-2689. [open access]

Abstract: Biomass can be converted via fermentation, pyrolysis, gasification, or combustion to a variety of bioenergies, and each conversion technology generates streams with different flows and CO2 concentrations that can undergo carbon capture. We use system-wide optimization models to determine the conversion technologies and level of carbon capture that lead to the minimum breakeven cost of fuel for a range of capacities and sequestration credits. We investigate how the optimal systems depend on constraints, such as energetic biorefinery self-sufficiency; and parameters, such as biomass availability. Pyrolysis to gasoline/diesel with hydrogen purchase produces liquid fuel for the lowest cost when energy purchase is allowed, with flue gas capture incentivized at sequestration credits of $48–54 per Mg CO2. With increasing sequestration credits, gasification to gasoline/diesel with carbon capture becomes optimal. When all bioenergies are considered, the cost per forward motion of electricity and hydrogen is lower than for liquid fuels because of the higher efficiency of electric motors and hydrogen fuel cells. We find that while gasification to electricity results in the greatest greenhouse gas mitigation under the current energy production mix, gasification to hydrogen is expected to result in the greatest mitigation in the future as the energy production mix changes.

Broader context: Bioenergy with carbon capture and sequestration (BECCS) is expected to be pivotal in global warming mitigation. BECCS systems include conversion technologies such as fermentation to ethanol, pyrolysis to gasoline/diesel, gasification to gasoline, combustion to electricity, and gasification to electricity or hydrogen. However, it is not yet clear which of these different conversion technologies with integrated carbon capture has the greatest economic and CO2 mitigation potential. Accordingly, we determine the cost-optimal BECCS strategy under a wide range of scenarios and assumptions. Looking into the future, we present the expected mitigation potential of the most promising BECCS strategies through 2050.

Industrial CO2 Capture Retrofit Database (IND CCRD)

This carbon capture retrofit database (CCRD) model allows users to evaluate the cost of carbon capture on industrial sources (ammonia, cement, ethanol, hydrogen, and natural gas processing). The model was created by the National Energy Technology Laboratory (NETL) based on the technical report titled Cost of Capturing CO2 from Industrial Sources.

The User Guide is available on the NETL website.

Implementing CO2 capture and utilization at scale and speed: The path to achieving its potential

CO2 capture and utilization (CCU) is an essential tool in the global carbon management toolkit. CCU can contribute to gigaton-scale removal of CO2 from the atmosphere and can serve as a source of carbon for many essential products made with carbon. It is important to understand, however, that effectively using CCU to help meet our climate goals means that we need to build an entirely new industry coupling carbon capture with carbon utilization. This report assesses the state of the emerging industry, identifies key actions that are needed, and projects market share for key products up to 2050 for a range of scenarios.

Carbon America, a carbon capture and sequestration (CCS) developer, announced today an agreement with Bridgeport Ethanol to develop a carbon capture and storage project in Nebraska. The project will capture and store approximately 175,000 tons of CO2 per year, equivalent to 95% of total emissions from the ethanol facility’s fermentation process. This is the first commercial project of its kind in the state of Nebraska.
