Hilaire, Jérôme; et al. (2019): Negative emissions and international climate goals—learning from and about mitigation scenarios

Hilaire, Jérôme; Minx, Jan C.; Callaghan, Max W.; Edmonds, Jae; Luderer, Gunnar; Nemet, Gregory F. et al. (2019): Negative emissions and international climate goals—learning from and about mitigation scenarios. In Climatic Change. DOI: 10.1007/s10584-019-02516-4.

"Most recent evidence stresses the importance of future socio-economic conditions in determining the flexibility of NET deployment and suggests opportunities for hedging technology risks by adopting portfolios of NETs. Importantly, our thematic review highlights that there is a much richer set of findings on NETs than commonly reflected upon both in scientific assessments and available reviews. "

Kramer, D. (2019): Commentary: Cutting carbon emissions isn’t enough

Kramer, David (2019): Commentary: Cutting carbon emissions isn’t enough. American Institute of Physics, 10/10/2019.

"To keep climate change in check, the US needs to lead the world in developing and deploying negative-emissions technologies for removing carbon dioxide."

Geden, Oliver; Schenuit, Felix (2019): Climate neutrality as long-term strategy. The EU’s Net Zero Target and Its Consequences for Member States

Geden, Oliver; Schenuit, Felix (2019): Climate neutrality as long-term strategy. The EU’s Net Zero Target and Its Consequences for Member States. In swp (C 33), pp. 1–4. DOI: 10.18449/2019C33.

"As a traditional frontrunner in international climate policy, the European Union (EU) is under great pressure to meet global expectations. In 2020, it must present its long-term decarbonisation strategy to the United Nations. Political attention has so far focussed on the lack of consensus among the Member States on whether they should adopt the European Commission’s proposed goal of “greenhouse gas neutrality” by 2050."

Daggash, H.; et al. (2019): Higher Carbon Prices on Emissions Alone Will Not Deliver the Paris Agreement

Daggash, Habiba Ahut; Mac Dowell, Niall (2019): Higher Carbon Prices on Emissions Alone Will Not Deliver the Paris Agreement. In: Joule. DOI: 10.1016/j.joule.2019.08.008.

"We investigate the effectiveness of carbon prices in achieving the deep decarbonization needed in the power system. We find that if only CO 2 emitters are penalized, increasing prices to the social cost of carbon is sufficient to achieve a decarbonized system in the medium-term but not maintain it in the long-term."

Mac Dowell, N.; et al. (2019): Negative Emissions: Priorities for Research and Policy Design

Mac Dowell, Niall; Fajardy, Mathilde; Daggash, Habiba; Patrizio, Piera (2019): Negative Emissions: Priorities for Research and Policy Design. In: Front. Clim. 1, S. 6. DOI: 10.3389/fclim.2019.00006.

"Five CDR technologies – including afforestation/reforestation, bioenergy with carbon capture and Storage, biochar, direct air capture and enhanced weathering – are compared in this work. We discuss main technical, socio-economic and regulatory bottlenecks that have been scarcely investigated at regional level, and provide directions for further research. We identify the availability of accessible land, water, low carbon energy and CO2 storage as key regional drivers and bottlenecks to most CDR technologies. We discuss the caveats in CO2 accounting in assessing the performance of each technology, and the need for an international regulatory framework which captures these differences."

Baird, J. (2019): The integrated thermodynamic geoengineering/negative emissions OTEC model

Baird, Jim (2019): The integrated thermodynamic geoengineering/negative emissions OTEC model. Energy Central. Available online at https://www.energycentral.com/c/ec/integrated-thermodynamic-geoengineeringnegative-emissions-otec-model.

"The solution advanced in this paper is an amalgam of energy production through the conversion of the heat of global warming to productive energy, (thermodynamic geoengineering (TG)), solar radiation management (SRM) through load balancing trapped solar energy and carbon-dioxide removal (CDR) thru negative-CO2-emissions ocean thermal energy conversion (NEOTEC)."

Tan, R. R.; et al. (2019): A linear program for optimizing enhanced weathering networks

Tan, Raymond R.; Aviso, Kathleen B. (2019): A linear program for optimizing enhanced weathering networks. In Results in Engineering 3, p. 100028. DOI: 10.1016/j.rineng.2019.100028.

"The model proposed here can determine optimal matches of sources and sinks in EW-based CMNs, considering material flow and temporal constraints. A case study is solved to illustrate the model."

Hohlwegler, P. (2019): Moral Conflicts of several “Green” terrestrial Negative Emission Technologies regarding the Human Right to Adequate Food – A Review

Hohlwegler, Patrick (2019): Moral Conflicts of several “Green” terrestrial Negative Emission Technologies regarding the Human Right to Adequate Food – A Review. In: Adv. Geosci. 49, S. 37–45. DOI: 10.5194/adgeo-49-37-2019.

" In this paper, I investigated whether BECCS, AR and EW would cause moral conflicts regarding the human right to adequate food if implemented on a scale sufficient to limit global warming “to well below 2 C”. Reviewing recent publications concerning BECCS, AR and EW, I found that EW would not conflict with the human right to adequate food but would likely even promote agricultural food production due to a higher nutrient provision."

Tan, R. R.; et al. (2019): Optimal synthesis of negative emissions polygeneration systems with desalination

Tan, Raymond R.; Aviso, Kathleen B.; Foo, Dominic C.Y.; Lee, Jui-Yuan; Ubando, Aristotle T. (2019): Optimal synthesis of negative emissions polygeneration systems with desalination. In: Energy, S. 115953. DOI: 10.1016/j.energy.2019.115953.

"In this paper, a novel scheme that integrates the ROD/IOC process with combined cooling, heating, and power (CCHP) generation is proposed as a new negative emissions polygeneration system (NEPS). A mixed integer linear programming model is then developed for the optimal synthesis and operation of such a system. The model uses a multi-period formulation to account for hourly variations in product demand and electricity price."
