Energy storage systems (ESS) are seen as one of the main pillars for a renewable-based energy system. Selecting the most suitable and sustainable ESS for a given project is a problem that involves multiple stakeholders with quite often diverging objectives that cannot all be fulfilled by a single technology. Several studies are available that tackle this problem applying multi-criteria decision analysis (MCDA). However, these use very different Multi-Attribute Decision Making (MADM) approaches, criteria and goals for decision support, why their results are difficult to compare or to reproduce. This work presents a review of existing MCDA-literature using MADM as a tool for sustainability evaluation of grid-tied ESS. Available studies are summarized, the goals, used MADM methods, and quantification of criteria are analyzed and discussed to provide tentative recommendations. The reviewed studies cover multiple technologies ranging from electrochemical, mechanical or electric ESS. Considered criteria are mainly structured around technology, economy, society, and environment, comprising a high number of individual sub-criteria. The aggregation of these criteria is mainly realized through the Analytic Hierarchy Process (AHP) in combination with a wide set of other methods. The quantification of various criteria is often based on different literature sources wherein context-free data for cost, and environmental impacts are used, leading in some cases to inconsistent comparisons in the assessments. Only in a few cases, assessments are linked to specific application requirements, which are decisive factors for the design of an ESS. A minority of the reviewed works include a representative set of decision-makers in their approaches, wherein the number or type of participants is often not communicated transparently. Therefore, most of the studies are considered to have a limited orientation towards practical decision making, but they provide valuable information regarding MADM method development.

Germany has ambitious targets to produce 35 % of the needed electricity from Renewables (RES) mainly based on wind and solar power by 2020 and over 80 % by 2050 within the so called “Energiewende”. Energy storage is seen as a potential option to assure the safe RES system integration to achieve this goals. There is a high uncertainty and the resulting public discourse about the future demand of different storage technologies is driving further development of these technologies. A literature review of 9 studies and 10 expert interviews is carried out in line of a foresight exercise to tackle these uncertainties. The estimations of reviewed literature are based on models with a market perspective on energy storage demand. Most scenarios used in this models are built on top down logics, where processes at lower levels (technology, micro-economic sphere) are determined by dominant macro dynamics. Different storage technologies are only considered partially or in an aggregated way. The reviewed studies show that there is a high for potential storage on every time scale starting from the year 2030 to 2040. Analysed potentials vary depending on RES diffusion scenarios and excess rate assumptions which are estimated to be between 0 to 44 GW in 2050. Reviewed studies strongly integrate shared visions about system developments and formal analyses and provide important and valuable information about potential future implications regarding energy storage. But they only partially account, due to practical reasons, wider benefits, stakeholder opinions and continuous market and system changes. It is also not possible to account for discontinuities in the technological innovation process of energy storage within this quantitative approaches. Stakeholder interviews provide thus additional and helpful insights to the literature review. The stakeholders frame alternative potential future developments that could influence the market success and need for energy storage until 2050. Most important factors named where policy measures, new market models and decentralization of the energy system. As in literature there is a big uncertainty among experts about the importance of different storage technologies and if energy storage is in general the best option among other flexibility measures as grid reinforcement, flexible demand and flexible power plants. It remains thus impossible to provide suggestions regarding the development of single storage technologies.

The last decades have shown an increasing amount of research into expectations of science and technology. Especially for emerging technologies, expectations held by different stakeholder are guiding the direction of research and development. In this article the results of an investigation into the expectations of specific actors regarding the development of emerging battery technology for applications in the power grid are presented. It is set up as an explorative study within the framework of Constructive Technology Assessment (CTA). A number of studies since the 1990s have indicated a growing need for energy storage options in the power grid, where batteries appear to be capable of providing a range of valuable services to the grid. Cost-effectiveness on a large scale will however require considerable technical improvements. The configuration of energy storage may differ in the specific location and exploitation of the storage assets, as well as in the investments in new storage capacity. In this study the visions and expectations of several relevant actors are analysed using interviews and surveys in terms of expectations of technological development, expectations concerning stakeholder roles, and channels of interaction between the relevant actors. The results indicate a divide in expectations between the user side of the technology (the electric power industry) and the development side (academic researchers). Opinions differ with respect to the obstacles to technological development, the actors relevant in early technological development, and the most suitable channels for interaction between these actors. It follows from the theoretical background that conflicts in expectations provide the opportunity for the acceleration of technological development and adoption through stakeholder participation. Small interactive workshops, where conflicts identified in this paper are discussed, were identified as a suitable channel in order to reach consensus in visions and expectations for battery technology.

In this working paper is presented information on the Portuguese labour market developed with the support of the European project WORKS-“Work organisation and restructuring in the knowledge society”. Is still a on the process article and thus commentaries are welcome. The structure is based on the following topics: a) The employment policy (Time regimes - time use, flexibility, part-time work, work-life balance -, and the work contracts regimes – wages, contract types, diversity); b) Education and training (skilling outcomes, rules on retraining and further training, employability schemes, transferability of skills); c) Equal opportunities (relevance of equal opportunity regulation for restructuring outcomes, the role of gender and age regulation); d) Restructuring effects (policy on transfer of personnel, policy on redundancies, and participation or voice in restructuring).

Some of the phenomena where the “globalization” concept is applied include the internationalization of markets, globalization of culture, polítical hegemony of world by some states, or groups of states, the increasing power of supranational institutions, and the development of a global division of labour. A starting point to understand the global division of work is the study of how companies are re-structuring, once they are the key-actors in the decision on which work should be found and where. The “value chains” describe each step in the productive process of a final product or service. Separated units of value chains can be in the same company (in-house) or in different companies (outsourced). Similarly they can be in a same local, or in other location. Normalization of business processes, combined with digitalization of information and the development of telecommunication networks made possible the tele-mediated work. This paper presents results from the European WORKS project, where are studied Portuguese cases of firms that integrate globalized value chain, and are analized the implications on work organization models and the (new) professional structures.

On 19 and 20 October 2006, the Research Centre on Enterprise and Work Organisation (IET) organised the first international conference on “Foresight Studies on Work in the Knowledge Society”. It took place at the auditorium of the new Library of FCT-UNL and had the support of the research project “CodeWork@VO” (financed by FCT-MCTES and co-ordinated by INESC, Porto). The conference related to the European research project “Work Organisation and Restructuring in the Knowledge Society” (WORKS), which is financed by the European Commission. The main objective of the conference was to analyse and discuss research findings on the trends of work structures in the knowledge society, and to debate on new work organisation models and new forms of work supported by ICT.

Algunos de los fenómenos donde el concepto de “globalización” es aplicado incluyen la internacionalización de los mercados, la globalización de la cultura, el dominio político hegemónico del mundo por algunos estados poderosos, o grupos de estados, el poder creciente de organismos supranacionales, y el desarrollo de una división global de trabajo. De acuerdo con Radice, la globalización é generalmente definida como “un proceso a través de lo cual una proporción creciente de transacciones económicas, sociales e culturales ocurre directamente o indirectamente entre partners de países distintos” (Radice, 2004: 154). Un ponto de partida para entender la división global del trabajo debe ser la investigación de los modos como las empresas se reestructuran, una vez que son los actores-llave en la decisión sobre que trabajo debe ser encontrado y donde. Las “cadenas de valor” descriven cada etapa en el proceso productivo de un producto o un servicio final. La palabra “valor” en la frase “cadena de valor” dice respecto al valor añadido. Cada etapa en la cadena de valor implica recibir inputs, procesarlos, y entonces pasarlos a la unidad siguiente en la cadena, con el valor que está sendo adicionado no proceso. As unidades separadas da cadena de valor pueden estar dentro da misma empresa (in-house) o en distintas empresas (outsourced). Similarmente pueden estar en un mismo local, o en otra localización. La normalización de muchos procesos del negocio, combinada con la digitalización da información y el desarrollo de redes de telecomunicaciones de elevada capacidad ha tornado posible el trabajo tele-mediado, pudiendo este ser externalizado y/o re-localizado, conduciendo à introducción de una división de trabajo internacional no trabajo de procesamiento de información. Esta comunicación presentará algunos resultados derivados do proyecto europeo WORKS, donde son estudiados casos portugueses de empresas que justamente se integran en

This report begins with some general information and analysis of policy and regulation that were the subjects of discussion and exchange in the policy pillar in the first phase of WORKS. The second section is a synthesis of country information on general principles and trends of policy and policy enforcement. This is followed by a summary of sector information for the sectors chosen by the qualitative pillar to be the objects of empirical analysis. The last summarises research questions and dimensions to be guidelines for carrying out case studies and capturing the relevance and effects of policy and institutions at the workplace. –
