Mac Dowell, Niall; Fajardy, Mathilde (2017): Inefficient power generation as an optimal route to negative emissions via BECCS?

Mac Dowell, Niall; Fajardy, Mathilde (2017): Inefficient power generation as an optimal route to negative emissions via BECCS? In Environ. Res. Lett. 12 (4), p. 45004. DOI: 10.1088/1748-9326/aa67a5.

"We find that in all cases, a lower capital cost, lower efficiency BECCS plant is superior to a higher cost, higher efficiency facility from both environmental and economic perspectives. We show that it may be preferable to operate the BECCS facility in base-load fashion, constantly removing CO2 from the atmosphere and dispatching electricity on an as-needed basis. We show that the use of this 'spare capacity' to produce hydrogen for, e.g. injection to a natural gas system for the provision of low carbon heating can add to the overall environmental and economic benefit of such a system."

Environmental Research Web: Bioenergy carbon capture and storage plants ‘should be inefficient’

"An inefficient system for bioenergy with carbon capture and storage (BECCS) is always preferable from both an environmental and financial point of view, according to an analysis by researchers in the UK."

Independent: Crystal invented that can turn thin air into fuel and fight global warming

"A “spongy” crystal that can turn thin air into fuel by extracting carbon dioxide has been developed by scientists. The researcher said the light-activated material was a “critical step” towards making a high-value fuel while at the same time reducing the amount of the greenhouse gas in the atmosphere. It works by turning carbon dioxide into carbon monoxide, which can be turned into a useful source of energy."

FCEA Blog: Carbon geoengineers: the debt collectors of the future

"Indeed, a recent report showed how none of the world’s top industries would be profitable if they paid for the true cost of natural capital. Granted, there has been some progress in the global decarbonization effort, but to date this has occurred on the fringes and in the absence of any enforceable targets to limit the total amount of atmospheric CO2."

Global News Wire: Climeworks Wins First Helena Prize

"Helena, a global NGO and think tank, and The Boston Consulting Group (BCG), one of the world’s leading management consultancies, announced today that Zurich-based firm Climeworks has been named the first recipient of The Helena Prize, a worldwide award designed to spur and support young entrepreneurs fighting climate change. Climeworks is the first company to develop and install a commercial plant to capture carbon dioxide from the air."

The Conversation: Inaction on climate change risks leaving future generations $530 trillion in debt

"The Paris Agreement in 2015 saw the international community agree to limit warming to within 2°C. The Hansen team argue that the much safer approach is to reduce atmospheric concentrations of CO₂ from the current annual average of more than 400ppm (parts per million) back to 1980s levels of 350ppm. This is a moderately more ambitious goal than the aspiration announced in Paris to further attempt to limit warming to no more than 1.5°C. Many climate scientists and policymakers believe that either the 2°C or 1.5°C limits will only be possible with negative emissions because the international community will be unable to make the required reductions in time. "

Hansen, James; et al. (2017): Young people's burden. Requirement of negative CO2 emissions

Hansen, James; Sato, Makiko; Kharecha, Pushker; Schuckmann, Karina von; Beerling, David J.; Cao, Junji et al. (2017): Young people's burden. Requirement of negative CO2 emissions. In Earth Syst. Dynam. 8 (3), pp. 577–616. DOI: 10.5194/esd-8-577-2017

"Targets for limiting global warming thus, at minimum, should aim to avoid leaving global temperature at Eemian or higher levels for centuries. Such targets now require negative emissions, i.e., extraction of CO2 from the air. If phasedown of fossil fuel emissions begins soon, improved agricultural and forestry practices, including reforestation and steps to improve soil fertility and increase its carbon content, may provide much of the necessary CO2 extraction."
