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."

Fuss, Sabine; et al. (2016): Research priorities for negative emissions

Fuss, Sabine; Jones, Chris D.; Kraxner, Florian; Peters, Glen P.; Smith, P.; Tavoni, Massimo et al. (2016): Research priorities for negative emissions. In Environ. Res. Lett. 11 (11), p. 115007. DOI: 10.1088/1748-9326/11/11/115007.

"While there are few pathways to 2 °C that do not rely on negative emissions, 1.5 °C scenarios are barely conceivable without them. Building on previous assessments of NETs, we identify some urgent research needs to provide a more complete picture for reaching ambitious climate targets, and the role that NETs can play in reaching them."

Bollen, Johannes; Aalbers, Rob (2017): Biomass-Energy with Carbon Capture and Storage Should Be Used Immediately

Bollen, Johannes; Aalbers, Rob (2017): Biomass-Energy with Carbon Capture and Storage Should Be Used Immediately. CPB Netherlands Beureau for Economic Policy Analysis (CPB Policy Brief, 2017/02).

"The European Union aims at reducing its greenhouse gas emissions in 2050 by 80-95% in order to prevent climate change. In this Policy Brief we analyse the potential role of negative-emissions technology in reducing these emissions."

Mathias, Jean-Denis; et al. (2017): On our rapidly shrinking capacity to comply with the planetary boundaries on climate change

Mathias, Jean-Denis; Anderies, John M.; Janssen, Marco A. (2017): On our rapidly shrinking capacity to comply with the planetary boundaries on climate change. In Scientific reports 7, p. 42061. DOI: 10.1038/srep42061.

"Here, we use the DICE model to analyze the set of adaptive climate policies that comply with the two planetary boundaries related to climate change: (1) staying below a CO2 concentration of 550 ppm until 2100 and (2) returning to 350 ppm in 2100. Our results enable decision makers to assess the following milestones: (1) a minimum of 33% reduction of CO2 emissions by 2055 in order to stay below 550 ppm by 2100 (this milestone goes up to 46% in the case of delayed policies); and (2) carbon neutrality and the effective implementation of innovative geoengineering technologies (10% negative emissions) before 2060 in order to return to 350 ppm in 2100, under the assumption of getting out of the baseline scenario without delay."

POST (2017): Greenhouse Gas Removal

POST (2017): Greenhouse Gas Removal. UK Parliamentary Office of Science and Technology (POSTnotes, 549).

"The 2015 Paris Agreement called for a balance between sources of Greenhouse Gas (GHG) emissions and their removal by 2100 to halt global temperature rise. This POSTnote explains why Greenhouse Gas Removal (GGR) techniques may be required to achieve this goal, outlines the benefits of and concerns about them, and considers policy options."

Fridahl, Mathias (2017): Socio-political prioritization of bioenergy with carbon capture and storage

Fridahl, Mathias (2017): Socio-political prioritization of bioenergy with carbon capture and storage. In: Energy Policy 104, S. 89–99. DOI: 10.1016/j.enpol.2017.01.050 .

"This article provides a unique intercontinental mapping of the prioritization of BECCS for the long term transition of the electricity supply sector. Based on survey responses from 711 UN climate change conference delegates, the article reports the low prioritization of BECCS relative to alternative technologies, indicating an urgent need for studies of the socio-political preconditions for large-scale BECCS deployment."

Phys.org: Renewables can't deliver Paris climate goals: study

The study itself does not include NETs/BECCS systematically. "Expansion of renewable energy cannot by itself stave off catastrophic climate change, scientists warned Monday. Even if solar and wind capacity continues to grow at breakneck speed, it will not be fast enough to cap under two degrees Celsius (3.6 degrees Fahrenheit), the target set down in the landmark 2015 Paris climate treaty, they reported in the journal Nature Climate Change."
