17 Oct Exploring the French reserves of hydrocarbon source rock (shale oil and gas)

National Academy of Technologies of France (NATF)
2011
L’autonomie énergétique est un objectif majeur pour la France et l’Europe. Stratégiquement, notre pays peut-il renoncer à la recherche de nouvelles ressources énergétiques dans son sol ? La demande énergétique ne baissera pas significativement à court terme. Le développement de l’éolien et du solaire, en plus de son impact sur la hausse des prix de l’électricité, exigera plus d’énergie de support rapide lors des variations soudaines de vent ou d’ensoleillement. L’hydraulique n’y suffira plus et les turbines à gaz seront utilisées même si elles sont émettrices de CO2. Le gaz est incontestablement une source d’ajustement et de flexibilité du réseau électrique et, s’il provient de notre sol, offre une capacité à négocier sur les marchés de l’énergie.

17 Oct Big Data: a change of paradigm (Report only in French)

National Academy of Technologies of France (NATF)
2015
Big Data implies a revolution in IT, reaching from technology to applications and practices, enabling the analysis of vast pools of "digital traces". Data manipulation from smartphones and connected objects opens up new service opportunities and cost reductions of IT-systems. While it is a major issue for sciences, politics and citizens, this report looks at the impact on businesses: mastering these methods permits a new immediacy in customer relationships. Big data is a disruptive data-analysis methodology, replacing classic approaches by iterative loops and using detected patterns for operational effectiveness. It is a new way of massive parallel data-centred programming and of designing algorithms, due to treatment on a myriad of machines, high-performance requirements, and development of algorithms through learning. It is a major challenge and paradigm shift for Governments and companies, deserving strong support in terms of training and awareness.

17 Oct Biogas (Report only in French)

National Academy of Technologies of France (NATF)
2016
EDP Sciences 2016 Biogas, resulting from the decomposition of organic matter, is known since the late 18th century: swamp gas. In Europe, the production of biogas on an industrial scale takes off somewhere between 1980 and 1990. The report describes sources and processes for the generation of biogas: hermetically sealed waste dumps and the capture of biogas from anaerobic digestion; industrial anaerobic fermentation of household waste with different species of bacteria at different temperatures; fermentation of agricultural crop waste and animal droppings; processing of biodegradable sludge from waste water treatment plants; etc. Biogas plants using a second generation methanisation process at high temperatures have been built in Germany and Sweden. Biogas is regarded as a renewable energy but is not fit for industrial use in untreated form as it contains various contaminants that need to be filtered. The success of biogas as a substitute for natural gas depends on the financial incentives granted.

17 Oct Energy Vectors (English version)

National Academy of Technologies of France (NATF)
2012
Editions Le Manuscrit 2012 Energy procurement/uses, influenced by oil prices and climate change, may differ in different countries. These influences continue but time-scales change (e.g. for peak oil and gas). The Fukushima accident has shaken confidence into nuclear power. This Report proposes a robust methodology for making relevant economic and ecological choices related to energy transition. Focussing on the French situation, it deals with Energy Vectors: the support system delivering energy ready to use (electricity, petrol, gas, or heat, etc.) to consumers; the intermediary stage of vectors between sources (coal, gas, U, wind, hydro) and demand of final energy (for transport, heating, industrial processes, etc.). While end-consumers may not be aware of the source for the final energy, distinguishing between them would allow economic and ecological competition (when C02 emissions carry a price-tag). This report throws new light on the political decisions that must be taken and provides guidelines with a long-range relevance.

17 Oct Impact of ICT on world energy consumption – and carbon footprints (Report only in French)

National Academy of Technologies of France (NATF)
2015
EDP Sciences, 2015 The report analyses the impact of ICT’s worldwide energy consumption and greenhouse-gas emissions, considering the impacts generated by the operation of its various hardware and infrastructure, and the savings it spawns in other areas of activity. Conclusion: The final energy and carbon balance of all ICT categories together is clearly a positive one. In 2012, ICT accounted for 4.7% of worldwide electricity consumption, and a total carbon footprint of about 1.7 percent. These numbers are on an upwards trend, but in smaller proportions than the growing use of ICT, thanks to its contribution to reduce these footprints in other areas of activities such as in the transport sector, buildings, manufacturing industries, or even dematerialised procedures. The report focuses on the (global) transport/mobility sector benefitting from digitisation in and around vehicles and lists current lines of research aimed at better performance of computing, with lower energy consumption.

01 Oct Recommendations for an AI Strategy in Switzerland

Swiss Academy of Engineering Sciences (SATW)
October 2019
Authors: Alessandro Curioni, Lukas Czornomaz, Joachim Buhmann, Ernst Hafen, Manuel Kugler, Hervé Bourlard, Jana Koehler, Matthias Kaiserswerth, Anika Schumann Main themes: artificial intelligence Digital transformation is radically reshaping almost every aspect of our society. The explosion of artificial intelligence (AI) and big data analytics applications is enabled by the extreme availability of data in combination with the substantial computing power of modern highly distributed computing infrastructures connected by high-speed networks. Machine learning technologies can be trained to perform specific tasks with an efficiency and an accuracy that can supplement and, in some cases, outperform that of humans. These systems provide deep insights by learning from data and interactions with users, which is already leading to a profound transformation of numerous industries, professions, and society at large. The current state of AI is, however, still far from delivering truly intelligent behaviour that is comparable to human intelligence. An AI research strategy should therefore carefully analyse AI’s history with its various waves of large promises and conceptual shortcomings. Leading Swiss experts in AI have published their recommendations for a Swiss AI strategy. They advocate more intensive use of the technology and the creation of national data platforms, as data is a prerequisite for powerful algorithms.

08 Août Factsheet Bioplastics

Swiss Academy of Engineering Sciences (SATW)
August 2019
Authors: Roger Marti, Hans-Peter Meyer, Manfred Zinn Main themes: plastic, bioplastic, biopolymers Nature of publication: factsheet The first plastic, invented in the second half of the 19th century, was celluloid, produced from nitrocellulose and camphor. Bakelite was the first plastic based on repeating and identical building blocks, so-called monomers. Due to its unrivalled characteristics, Bakelite quickly found use in the rapidly growing automotive and electrical industries. Since then, “plastic” has been a major success and is found in practically all aspects of human life and in high-tech applications. The problem of plastic is related to its advantage: durability. It does not degrade completely, instead breaking down into ever smaller micro- and nanoparticles whose fate and influence on ecosystems are not yet clear. Is bioplastic a solution? The first SATW Innovation Forum on “Biopolymers” took place in November 2018. Invited stakeholders from academic research institutions, industry and administration discussed the current situation and possible shortcomings in Switzerland and charted possible scenarios for development. The publication shows why plastic has become a problem, what bioplastics are, and whether it needs regulation.

08 Juil Methane – where does it come from, what is its impact on the climate? (Report only in French)

National Academy of Technologies of France
(NATF) 2014
EDP Sciences 2014 Strong variations of atmospheric concentrations of the potent greenhouse gas methane have accompanied glacial and interglacial periods - influencing timetable and magnitude of past and present climate changes. The report describes and analyses natural and human-related sources and sinks of atmospheric methane with particular attention to potentially massive emissions from thawing permafrost and clathrates. The methane fluxes between main reservoirs and the atmosphere is measured via ground-based networks or from outer space. As atmospheric methane is destroyed over time (half-life ~7 years), its GHG-efficiency is not straight-forward. While fossil fuel exploitation is an important methane source, emissions could be limited at reasonable cost. Feedbacks from wetlands and soils are more difficult to control. Recommendations are made in areas such as agricultural practices, waste- and landfill management, biomass combustion, exploitation of coal, natural gas and oil. The potential exploitation of methane from permafrost and marine clathrates should be closely followed.
