Walsh, Brian; Ciais, Philippe; et al. (2017): Pathways for balancing CO2 emissions and sinks. In Nature Communications

Walsh, Brian; Ciais, Philippe; et al. (2017): Pathways for balancing CO2 emissions and sinks. In Nature Communications. doi:10.1038/ncomms14856

"We find that, barring unforeseen and transformative technological advancement, anthropogenic emissions need to peak within the next 10 years, to maintain realistic pathways to meeting the COP21 emissions and warming targets. Fossil fuel consumption will probably need to be reduced below a quarter of primary energy supply by 2100 and the allowable consumption rate drops even further if negative emissions technologies remain technologically or economically unfeasible at the global scale."

Climate Home: We already have a magic technology that sucks up carbon

"Why have emissions plans that rely on removing carbon from the air with unproven technologies when forests can do it today?"

Energy Collective: Carbon Capture on Biofuels: A Path to Net Negative Emissions

On BECCS. "On April 7, Archer Daniels Midland, the food processing and biofuels company, began permanently storing carbon dioxide 7000 feet underground, adjacent to its Decatur, Illinois corn ethanol plant.  At full capacity, the Illinois Industrial carbon capture and storage facility will prevent one million metric tonnes per year of carbon dioxide (CO2) from entering the atmosphere.  That is equivalent to taking more than 200,000 cars off the road, or eliminating emissions from more than 100,000 typical American homes."

Fajardy, Mathilde; Mac Dowell, Niall (2017): Can BECCS deliver sustainable and resource efficient negative emissions?

Fajardy, Mathilde; Mac Dowell, Niall (2017): Can BECCS deliver sustainable and resource efficient negative emissions? In Energy Environ. Sci. DOI: 10.1039/C7EE00465F

"In this contribution we present a whole-systems analysis of the BECCS value chain associated with the cultivation, harvesting, transport and conversion in dedicated biomass power stations in conjunction with CCS, of a range of biomass resources – both dedicated energy crops (miscanthus, switchgrass, short rotation coppice willow), and agricultural residues (wheat straw)."

Work For Rain (Blog): Bioenergy with Carbon Capture and Storage: Climate Savior or Goat?

"BECCS means burning biomass for energy, separating CO2 in the process, and then injecting this gas deep underground in a reservoir capped by non-porous rock or mineral. Of the 116 scenarios that the Intergovernmental Panel on Climate Change’s (IPCC) most recent Fifth Assessment Report suggests will stabilize our climate by the end of the century, 101 of them rely on BECCS."

Rockström, Johan; et al. (2017): A roadmap for rapid decarbonization

Rockström, Johan; Gaffney, Owen; Rogelj, Joeri; Meinshausen, Malte; Nakicenovic, Nebojsa; Schellnhuber, Hans Joachim (2017): A roadmap for rapid decarbonization. In Science 355 (6331), pp. 1269–1271. DOI: 10.1126/science.aah3443.

Including negative emissions/BECCS. "Complemented by immediately instigated, scalable carbon removal and efforts to ramp down land-use CO2 emissions, this can lead to net-zero emissions around mid-century, a path necessary to limit warming to well below 2°C."

Harrison, Daniel P. (2017): Global negative emissions capacity of ocean macronutrient fertilization

Harrison, Daniel P. (2017): Global negative emissions capacity of ocean macronutrient fertilization. In Environ. Res. Lett. 12 (3), p. 35001. DOI: 10.1088/1748-9326/aa5ef5.

"Utilizing global datasets of oceanographic field measurements, and output from a high resolution global circulation model, the current study provides the first comprehensive assessment of the global potential for carbon sequestration from ocean macronutrient fertilization (OMF). Sufficient excess phosphate exists outside the iron limited surface ocean to support once-off sequestration of up to 3.6 Pg C by fertilization with nitrogen. Ongoing maximum capacity of nitrogen only fertilization is estimated at 0.7 ± 0.4 Pg C yr−1. "

Minx, Jan C.; et al. (2017): Fast growing research on negative emissions

Minx, Jan C.; Lamb, William F.; Callaghan, Max W.; Bornmann, Lutz; Fuss, Sabine (2017): Fast growing research on negative emissions. In Environ. Res. Lett. 12 (3), p. 35007. DOI: 10.1088/1748-9326/aa5ee5

"In this paper we use scientometric methods and topic modelling to identify and characterize the available evidence on NETs as recorded in the Web of Science. We find that the development of the literature on NETs has started later than for climate change as a whole, but proceeds more quickly by now. A total number of about 2900 studies have accumulated between 1991 and 2016 with almost 500 new publications in 2016."

Greene, Charles H.; et al. (2017): Geoengineering, Marine Microalgae, and Climate Stabilization in the 21 st Century

Greene, Charles H.; Huntley, Mark E.; Archibald, Ian; Gerber, Léda N.; Sills, Deborah L.; Granados, Joe et al. (2017): Geoengineering, Marine Microalgae, and Climate Stabilization in the 21 st Century. In Earth's Future. DOI: 10.1002/2016EF000486.

"Here, we describe an alternative approach based on the large-scale industrial production of marine microalgae. When cultivated with proper attention to power, carbon, and nutrient sources, microalgae can be processed to produce a variety of biopetroleum products, including carbon neutral biofuels for the transportation sector and long-lived, potentially carbon-negative construction materials for the built environment."

Geoengineering Monitor: Pulling carbon out of the air: NETS, BECCS, and CDR

"Geoengineering Monitor has long reported on the speculative concept of “negative emissions”, together with certain favored approaches such as bioenergy with carbon capture and storage (BECCS) – a geoengineering technique which recent studies show would have significant negative impacts on biodiversity, food security, and livelihoods. To get a better sense of the technologies under discussion, we sent a correspondent to a “Carbon Dioxide Removal / Negative Emissions Technologies (NETs)” workshop earlier this month, co-sponsored by fora associated with American University, University of California – Berkeley, and Arizona State University."
