Бароосмотичний аналіз як новий метод гідрогеологічних досліджень
Запропоновано методику бароосмотичного аналiзу гiдрогеологiчних даних для окремих свердловин, за якою визначаються величина бароосмотичного напору H2O у пластових (порових) водах i ступiнь вiдхилення їх вiд стану бароосмотичної рiвноваги на кiлькох водоносних горизонтах. Результати аналiзу для чотирьох свердловин з рiзних регiонiв пiдтвердили iснування вертикальних бароосмотичних потокiв у глинистих товщах усiх розрiзiв i дали змогу визначити напрями цих потокiв та виявити зони впливу особливих локальних гiдрогеологiчних процесiв.Methods of baroosmotic analysis of hydrogeological data for separate boreholes have been proposed. They can be applied to determine the baroosmotic pressure of H2O in formational (porous) waters and the degree of their defection from the state of baroosmotic balance at several water-bearing horizons. The results of analysis conducted at 4 boreholes from different regions have confirmed the existence of vertical baroosmotic flows in clayey units of all sections and have allowed us to determine the directions of these flows and to reveal the zones affected by specific local hydrogeological processes
How China became a leader in solar PV: An innovation system analysis
In this paper we focus on understanding the rapid rise of the Chinese PV industry and its profound impact on the global PV industry. We investigate how it is possible that a nation that is still focusing on catching up in terms of industry, innovation and technology has been able to bring manufacturers from leading industrialized nations to their knees. This paper applies the framework of the Technological Innovation System (TIS), and also takes the context into account, in terms of the Chinese national innovation system (NIS) and the global PV TIS. It concludes that the rise of the Chinese PV TIS can be explained by the interaction of three context factors (the change in Chinese institutions, technology transfer, and the large European market) and specific PV TIS dynamics. The study empirically shows the importance of extending the national TIS studies by including the influences of context factors
The influence of perceived uncertainty on entrepreneurial action in the transition to a low-emission energy infrastructure: The case of biomass combustion in the Netherlands
Abstract
The transition towards renewable energy production will not occur without the involvement of entrepreneurs who dare to take action amidst uncertainty. In an earlier article [1], a conceptual model was introduced for analyzing how perceived uncertainties influence the decisions and actions of entrepreneurs involved in innovation projects that aimed at developing and implementing renewable energy technologies. In this article, the conceptual model is applied to stand-alone biomass combustion projects in the Netherlands. Although none of the biomass combustion projects has been abandoned, some entrepreneurs clearly have more difficulty to turn their project into a success than others. To create insight into the underlying dynamics of these projects, the article analyzes what types of positive or negative interaction patterns occur over time between (internal or external) factors in the project environment, perceived uncertainties, motivation and entrepreneurial action and how these patterns can be stimulated or prevented. The results provide several lessons to take into account when designing policies for stimulating the development and implementation of biomass combustion

Dynamics of Technological Innovation Systems : The case of biomass energy
The starting point is that the current energy system is largely dependant on fossil fuels. This phenomenon, which is labelled as carbon lock-in by Unruh (2000), makes the breakthrough of renewable energies long, slow, and tedious. The most suitable theoretical approach to analyse the development, diffusion and implementation of emergent technologies, such as renewable energies, is the Technological Innovation Systems' (TIS) perspective as developed by Carlsson and Stanckiewicz (1991). This approach focuses on a particular technology and includes all those factors (institutions, actors, and networks) that influence its development. Recent research has identified several so-called System Functions that need to be fulfilled for a TIS to support successfully the evolution of a technology. In this paper we will use the following set of System Functions: F1: Entrepreneurial Activities, F2: Knowledge Development (learning), F3: Knowledge Diffusion through Networks, F4: Guidance of the Search, F5: Market Formation, F6: Resources Mobilisation, F7: Counteracting Resistance to Change (also Support from Advocacy Coalitions). By focusing on the System Functions the key processes that occur in a system which influence the development, diffusion and implementation of that technology will be identified and insight will be gained in the system dynamics. The System Functions are not independent but interact and influence each other. The nature of interactions whether they are positive or negative will influence the performance of the system respectively. Positive System Function fulfilment can lead to positive, i.e. virtuous cycles of processes that strengthen each other and lead to the building up of momentum that creates a process of creative destruction within the incumbent system (Jacobsson and Bergek 2004). According to the same reasoning, a system in decline is characterised by one or more vicious cycles, where the System Functions interact and reinforce each other in a negative way. The results from the case studies showed that different functional patterns occurred for the Biomass Innovation Systems. These can be divided into virtuous and vicious cycles. In the case of virtuous cycles a successful diffusion of the respective technologies occurred (for example biomass digestion in Germany and biomass co-firing in the Netherlands), whereas low diffusion is observed for the technologies (for example biomass digestion, biomass gasification and stand-alone biomass combustion in the Netherlands) where vicious cycles dominated the system. Furthermore, the findings show that biomass technologies go through long-term trajectories (10-30 years) of development, diffusion and implementation. However, the Dutch government only provided short-term policies and removed all support when the technical problems were not solved within this short term. In order to accelerate the diffusion of biomass energy technologies a long-term and stable guidance by the government is needed where time and space for trial and error are provided, where a market is formed and where entrepreneurs pack together to lobby for better institutional conditions for their technology
Explaining the success of emerging technologies by innovation systems functioning: the case of biomass digestion in Germany
We examine the view that the success of emerging technologies may be understood using a technological innovation systems analysis, drawing on a system functions approach. This is done in the context of a case study of the successful diffusion of biomass digestion technology in Germany. We show that that all system functions that are claimed to be important within the innovation systems approach are present in the German Biomass Innovation System; and that these system functions positively interact leading to virtuous cycles and a rapid growth of the German Biomass Digestion Innovation System
Functions of innovation systems as a framework to understand sustainable technological change: Empirical evidence for earlier claims
Understanding the emergence of innovation systems is recently put central in research analysing the process of technological change. Especially the key activities that are important for the build up of an innovation system receive much attention. These are labelled ‘functions of innovation systems’. This paper builds on five empirical studies, related to renewable energy technologies, to test whether the functions of innovation systems framework is a valid framework to analyse processes of technological change. We test the claim that a specific set of functions is suitable. We also test the claim made in previous publications that the interactions between system functions accelerate innovation system emergence and growth. Both claims are confirmed
Identifying Typical (Dys)-functional interaction patterns in the Dutch Biomass Innovation System
Contextual structures and interaction dynamics in the Brazilian Biogas Innovation System
Although biogas technologies in Brazil have a huge potential and a long history few studies have examined biogas in Brazil as a technological field. Accordingly, this paper aims to understand which conditions enabled or constrained the diffusion of biogas technologies. More specifically, this research applies and adapts the Technological Innovation System (TIS) framework to examine biogas-specific and context-related conditions as well as their interplay. Data were collected by performing an event history analysis from 1979 to 2016 along with 24 in-depth expert interviews. Our findings indicate that the evolution of geographically embedded sectoral regulations and infrastructures as well as their interactions have been responsible for major changes in the biogas field in Brazil. By demonstrating how this occurred, this research has opened up new possibilities to promote biogas technologies in Brazil. This study also provides an important analytical method that focuses on exploring activities and their background conditions to consider contextual influences in TIS. Consequently, three major ways of contextual influences for TIS studies are suggested – evolution of contextual structures, interaction of contextual structures and translation of external events by these interactions
