Paris Interdisciplinary Energy Research Institute - LIED
Présentation
Paris Interdisciplinary Energy Research Institute debates over energy sourcing and climate protection have led to widespread interest in a coming energy transition. The PIERI has been conceived in this context of continuous growth in world energy demand and pressing environmental concerns, notably climate change.
Although the need for concerted action is widely acknowledged, research in these fields is mostly conducted on a fragmented, mono-disciplinary basis. The aim of the PIERI is to bring together researchers from sciences, technologies and the social sciences – drawn from both the public and private sectors – into a single, federative structure. Its objectives are to develop interdisciplinary perspectives on energy issues, to nurture fundamental discoveries on energy sourcing, to develop empirical applications, to promote knowledge transfer to companies, to understand societal impacts and to inform policy-making processes.

Thèmes de recherche
The LIED and its international network PIERI (Paris Interdisciplinary Energy Research Institute) have been launched in the context of increased worldwide demands in energy in the face of environmental concerns, i.e. sustainable resources and impact on the climate.
The LIED favours a global approach and aims at resolving questions at the national and international level by a unique multi-disciplinary approach encompassing basic science (Biology, Chemistry, Physics, Informatics, Mathematics, Earth sciences and Engineering) as well as social sciences (Anthropology, Economics, Geography, History, Philosophy, Political sciences), whether in the academic or industrial domain.
· Objectives : Develop basic and applied science in response to the challenges of the “energy transition” with a focus on the interaction between energy, environment and climate. In the domain of biology, the LIED aims at understanding the basic mechanisms underlying energetic processes in microorganisms and in plants. It fosters applied science for the development of production and transformation of biomass.
· Methods : Biochemistry, Genetics, Genomics, Molecular and cellular biology, Bioinformatics.
. Research orientations : balancing fundamental and applied research.
The work of the PIERI is organised around four axes :
♦ Fundamental science and low-carbon energy sources ;
♦ The science and technology of energy efficiency ;
♦ Forecasting, social and economic analysis, and public policy studies ;
♦ Interdisciplinary epistemology.
The titles of first two axes already illustrate the aspiration to combine fundamental and applied research. Two complementary research groups have been established, entitled : ‘Innovative energy sources and biomaterials’ and ‘Energy transport, instabilities and fluctuations’, composed mainly of researchers from sciences and technologies, but with input from social scientists. The third axis is subdivided into six themes, which all bring together the physical and the social sciences, namely :
The geography of energy sourcing ;
The multilevel governance of energy ;
Social representation and innovation : hydrogen and other energy pathways ;
Energy efficiency and modes of consumption ;
Forecasting models and interdisciplinary convergence ;
Smart grids.

[hal-03681304] Cakile maritima, a promising model for halophyte studies and a putative cash crop for saline agriculture
Date: 30 May 2022 - 12:20
Desc: Agricultural intensification necessary for global food security as well as changes in temperature and precipitation patterns expected from climate change are likely to cause further deterioration irrigated lands in various part of the world. Salinization is spreading particularly in arid and semi-arid regions and urban sprawl is forcing agricultural production into marginal areas. Many salted marginal areas could support biomass production if halophytes able to tolerate high salinity were used. This chapter presents general data on Cakile maritima, a halophyte, concerning its ecological characteristics, diversity and distribution, adaptation to environment and its potential uses as medicinal plant, for oilseed production or phytoremediation. In a second part we present what have been uncovered in C. maritima in term of mechanisms and physiological adaptations to salinity when compared to other plants. Cakile maritima appears worthy of attention since it meets numerous criteria for being a good genetic model of halophyte. It has a small diploid genome, a short life cycle and produces large amount of seeds. Furthermore Cakile maritima represents a promising species owing its large geographical and ecological amplitude, its economic potential because of its ability to produce numerous secondary compounds and as an oilseed and energy crop. This renders the cultivation of this plant on salted marginal soil of practical significance in the context of the necessary development of biosaline agriculture in the future
[hal-03681735] Establishment of a cell suspension culture of the halophyte Cakile maritima
Date: 30 May 2022 - 16:06
Desc: Cakile maritima is a member of the Brassicaceae family also known as sea rocket. It is an annual succulent halophyte frequent in coastal dune vegetation in Mediterranean regions and Atlantic coasts from North Africa to the north of Europe. This halophyte presents a complex survival strategy at high salinity and its seeds contain up to 40% of an oil which could be suitable for biofuel production and other industrial applications. However, data concerning the cellular mechanisms allowing this plant to resist salinity are still lacking. Cell suspension cultures offer an in vitro system convenient for cell biology studies and biotechnological methods are still not developed for this putative crop. The present paper reports initiation of C. maritima cell suspension cultures from callus obtained from aerial parts of seedlings. The establishment of a suspension culture which preserves its salt resistance provides an opportunity to gain insights into C. maritima biology.

[hal-01744697] Buoyancy-driven destabilization of an immersed granular bed
Date: 27 Mar 2018 - 16:37
Desc: Under suitable conditions, an immersed granular bed can be destabilized by local thermal forcing and the induced buoyant force. The destabilization is evident from the triggering and establishment of a dense fluid-like granular plume. Varying the initial granular layer average height h, time series of the free layer surface are extracted, allowing us to dynamically compute the underlying volume of the granular layer. The initial interface deformation, the lowering of the average granular interface (i.e. decrease of the granular layer volume) and the emission of a plume are observed and analyzed. We show that the phenomenon is mainly driven by heat transfer, for large h and also involves variable height thermal boundary condition & Darcy's flow triggering, for small h. Simple modeling with no adjustable parameter not only allows us to capture the observed scaling power laws but is also in quantitative agreement with the obtained experimental data.
[hal-01071249] A statistical mechanics framework for the large-scale structure of turbulent von Kármán flows
Date: 6 Feb 2015 - 19:19
Desc: In the present paper, recent experimental results on large scale coherent steady states observed in experimental von Kármán flows are revisited from a statistical mechanics perspective. The latter is rooted on two levels of description. We first argue that the coherent steady states may be described as the equilibrium states of well-chosen lattice models, that can be used to define global properties of von Kármán flows, such as their temperatures. The equilibrium description is then enlarged, in order to reinterpret a series of results about the stability of those steady states, their susceptibility to symmetry breaking, in the light of a deep analogy with the statistical theory of Ferromagnetism. We call this analogy ''Ferro-Turbulence
