The Conversation: Carbon capture on power stations burning woodchips is not the green gamechanger many think it is

"The UK’s efforts to develop facilities to remove carbon emissions from power stations took a step forward with news of a demonstrator project getting underway at the Drax plant in north Yorkshire. Where most electricity carbon capture projects have focused on coal-fired power, the Drax project is the first to capture carbon dioxide (CO₂) from a plant purely burning wood chips – or biomass, to use the industry jargon."

Emerson, D. (2019): Biogenic Iron Dust: A Novel Approach to Ocean Iron Fertilization as a Means of Large Scale Removal of Carbon Dioxide From the Atmosphere

Emerson, D. (2019): Biogenic Iron Dust: A Novel Approach to Ocean Iron Fertilization as a Means of Large Scale Removal of Carbon Dioxide From the Atmosphere. In: Front. Mar. Sci. 6, S. 3944. DOI: 10.3389/fmars.2019.00022.

"This is a proposal for ocean iron fertilization as a means to reduce atmospheric carbon dioxide levels. The idea is to take advantage of nanoparticulate, poorly crystalline Fe-oxides produced by chemosynthetic iron-oxidizing bacteria as an iron source to the ocean. Upon drying these oxides produce a fine powder that could be dispersed at altitude by aircraft to augment wind-driven Aeolian dust that is a primary iron source to the open ocean."

Prajapati, A.; et al. (2019): Assessment of Artificial Photosynthetic Systems for Integrated Carbon Capture and Conversion

Prajapati, A.; Singh, M. (2019): Assessment of Artificial Photosynthetic Systems for Integrated Carbon Capture and Conversion. In: ACS Sustainable Chem. Eng. DOI: 10.1021/acssuschemeng.8b04969.

"Sustainable and continuous operation of an artificial photosynthetic (AP) system requires a constant supply of CO2 captured from the dilute sources such as the flue gas and the air to make fuels and chemicals. Although the architecture of AP systems resembles that of the natural leaves, they lack an important component like stomata to capture CO2 directly from the dilute sources. Here we design and evaluate the solar-to-fuel (STF) efficiency of the integrated AP system that captures CO2 directly from the air/flue gas and converts it to fuels using sunlight."

Bellamy, R.; et al. (2019): Perceptions of bioenergy with carbon capture and storage in different policy scenarios

Bellamy, R.; Lezaun, J.; Palmer, J. (2019): Perceptions of bioenergy with carbon capture and storage in different policy scenarios. In: Nat Comms 10 (1), S. 743. DOI: 10.1038/s41467-019-08592-5.

"There is growing interest in bioenergy with carbon capture and storage (BECCS) as a possible technology for removing CO2 from the atmosphere. In the first study of its kind, we investigate whether and how different forms of incentivisation impact on public perceptions of this technology. We develop a new experimental method to triangulate perceptions of BECCS in different policy scenarios through quantitative measurement and qualitative elicitation. Here we show that the type of policy instrument used to incentivise BECCS significantly affects perceptions of the technology itself."

Foreign Affairs: Less Than Zero

"Most Americans used to think about climate change—to the extent that they thought about it at all—as an abstract threat in a distant future. But more and more are now seeing it for what it is: a costly, human-made disaster unfolding before their very eyes."

ScienceDaily: Carbon dioxide sequestration accompanied by bioenergy generation using a bubbling-type photosynthetic algae microbial fuel cell

"Researchers have proposed a design solution that could bring artificial leaves out of the lab and into the environment. Their improved leaf, which would use carbon dioxide -- a potent greenhouse gas -- from the air, would be at least 10 times more efficient than natural leaves at converting carbon dioxide to fuel."

Li, M.; et al. (2019): Carbon dioxide sequestration accompanied by bioenergy generation using a bubbling-type photosynthetic algae microbial fuel cell

Li, M.; Zhou, M.; Luo, J.; Tan, C.; Tian, X.; Su, P.; Gu, T. (2019): Carbon dioxide sequestration accompanied by bioenergy generation using a bubbling-type photosynthetic algae microbial fuel cell. In: Bioresource Technology 280, S. 95–103. DOI: 10.1016/j.biortech.2019.02.038.

"This study developed a bubbling-type photosynthetic algae microbial fuel cell (B-PAMFC) to treat synthetic wastewater and capture CO2 using Chlorella vulgaris with simultaneous power production. The performance of B-PAMFC in CO2 fixation and bioenergy production was compared with the photosynthetic algae microbial fuel cell (PAMFC) and bubbling photobioreactor. Different nitrogen sources for C. vulgaris growth, namely sodium nitrate, urea, ammonium acetate and acetamide were studied."

CEPS: Sinking to Zero: the role of carbon capture and negative emissions in EU climate policy

"The updated EU long-term climate strategy with its net-zero emissions objective and the IPCC's Special Report on the 1.5°C target prompt a renewed strategic look at negative emissions and carbon capture. Reaching net-zero greenhouse gas emissions requires more carbon sinks and other approaches to remove CO2 from the atmosphere."

The New York Times Magazine: The Tiny Swiss Company That Thinks It Can Help Stop Climate Change

"[...] These were “direct air capture” machines, which soon would begin collecting carbon dioxide from air drawn in through their central ducts. Once trapped, the CO₂ would then be siphoned into large tanks and trucked to a local Coca-Cola bottler, where it would become the fizz in a soft drink."

Chatham House: Cool idea or hi-tech madness?

"As the threat from climate change looms ever larger, growing attention is being paid to proposals that sound as if they come straight from a sci-fi novel. One idea is to spray the stratosphere with particulates to reflect sunlight, thus reducing the temperature of planet Earth."
