Formic acid synthesis using COâ as raw material: Techno-economic and environmental evaluation and market potential
The future of carbon dioxide utilisation (CDU) processes, depend on (i) the future demand of synthesised products with COâ, (ii) the availability of captured and anthropogenic COâ, (iii) the overall COâ not emitted because of the use of the CDU process, and (iv) the economics of the plant. The current work analyses the mentioned statements through different technological, economic and environmental key performance indicators to produce formic acid from COâ, along with their potential use and penetration in the European context. Formic acid is a well-known chemical that has potential as hydrogen carrier and as fuel for fuel cells. This work utilises process flow modelling, with simulations developed in CHEMCAD, to obtain the energy and mass balances, and the purchase equipment cost of the formic acid plant. Through a financial analysis, with the net present value as selected metric, the price of the tonne of formic acid and of COâ are varied to make the CDU project financially feasible. According to our research, the process saves COâ emissions when compared to its corresponding conventional process, under specific conditions. The success or effectiveness of the CDU process will also depend on other technologies and/or developments, like the availability of renewable electricity and steam
Coal in the 21st Century: a climate of change and uncertainty
Coal presents a particular set of challenges when balancing energy policy goals. Despite presenting viable solutions to the problems of energy security and global energy poverty, coal struggles, given its greenhouse-gas drawbacks, in a world of increasingly harmful climate change. Notwithstanding the harm caused to the environment, coal remains an expanding low-price route to meeting local energy needs. It is forecasted to remain a major global resource for the foreseeable future. In the short term it is predicted to have a 26% share of the global energy mix. Recent years have witnessed severe deviations from previously stable trends in coal markets and policy dynamics. According to the predictions by the International Energy Agency (IEA), a variety of factors ranging from the planned phase-out of coal in countries such as Denmark, France and the UK, to changes in policy in China and import-dependency in India, and demand drop in the US have together resulted in the largest decline in coal production in 2015 since 1971 (IEA, Coal Information, 2016). This paper seeks to outline basic coal facts, recent market trends and directions globally and provides an overview of issues shaping the future of coal in the twenty-first century.

Societal Innovation: between dream and reality lies complexity
Jan Rotmans (1961) is one of the founders of Integrated Assessment (IA), and has outstanding experience in IA modeling, scenario-building, uncertainty
management and transition management. During the past twenty years he has led a diversity of innovative projects in the field of climate change, global change,
sustainable development and transitions and system innovations. He is founder
and director of the International Centre for Integrative Studies (ICIS) (1998) at Maastricht University. Since 2004 he is a full professor in Transitions and
Transition Management at Erasmus University Rotterdam in the Netherlands, where he founded the DRIFT-institute: Dutch Research Institute For Transitions.
He is vice-president of The Integrated Assessment Society (TIAS), and founder and director of the Dutch Knowledge Network on System Innovations and Transitions
(KSI). Jan Rotmans is founder of two scientific journals, Environmental Modeling and Assessment and Integrated Assessment, and has published ten books and more than 150 peer-reviewed scientific articles in journals and books in the fields of
environment, sustainability, governance, transitions and system innovations.There are no easy, off-the-shelf solutions for persistent societal problems, because these are caused by fundamental flaws in our societal systems. Such systemic errors demand radical changes in our thinking and actions, i.e. transitions and system innovations. Transitions require a long period (one to two generations), and take time, patience, money, confidence, but also courage, daring and perseverance to gain the upper hand over various types of resistance.
Research into transitions is by definition multidisciplinary and interdisciplinary. For this we need knowledge and experience from systems analysis, social administration, history, innovation science, economics, business administration and technology. The nature of research into transitions is fundamental, explorative, creative and practical.
A conceptual framework for research into transitions is presented that consists of four interlinked conceptual building blocks, which in turn provide an outline of a transition theory in its embryonic stages. These concepts are rooted in common notions from complexity theory, new forms of governance and social theory. Central here is the concept of transition management, for which a new management framework is developed.
Transition management is an attempt to tackle persistent stubborn problems by steering them in a more sustainable direction, through a visionary, cyclical process of putting issues on the agenda, learning, orchestrating and experimenting. Not based on management and control but through clever, subtle changes and adjustments at several levels concurrently. Transition management is a very promising management concept that can initially be applied to a wide range of complex societal problems: from health care to energy provision, and from social security to mobility. Transition management can also be applied to complex processes of change in a business context.Voor hardnekkige maatschappelijke problemen bestaan geen pasklare oplossingen. Deze zijn het gevolg van weeffouten in onze maatschappelijke stelsels. Deze systeemfouten vergen radicale veranderingen in ons denken en handelen: transities en systeeminnovaties. Transities vergen een lange periode (1 Ă 2 generaties), en kosten tijd, geduld, geld, vertrouwen, maar ook moed, durf en doorzettingsvermogen om verschillende soorten weerstand te overwinnen.
Onderzoek naar transities is per definitie multi-en interdisciplinair, waarbij kennis nodig is vanuit de systeemkunde, bestuurskunde, geschiedenis, innovatiewetenschappen, economie, bedrijfskunde en techniek. Transitieonderzoek is zowel fundamenteel, exploratief, ontwerpend en praktisch van aard.
Een conceptueel kader voor transitieonderzoek wordt gepresenteerd, dat bestaat uit een viertal samenhangende conceptuele bouwstenen, die de contouren vormen van een transitietheorie in wording. Deze concepten zijn geworteld in gemeenschappelijke noties uit de complexiteitstheorie, nieuwe vormen van governance en de sociale theorie. Centraal hierin staat het concept van transitiemanagement, waarvoor een nieuw sturingsraamwerk is ontwikkeld. Transitiemanagement beoogt hardnekkige problemen bij te sturen in een meer duurzame richting, via een visionair, cyclisch proces van agenderen, leren, instrumenteren en experimenteren. Niet op basis van controle en beheersing, maar via slim, subtiel schakelen en bijsturen op meerdere niveaus. Transitiemanagement is een veelbelovend sturingsconcept wat in beginsel toepasbaar is op tal van complexe maatschappelijke problemen: van gezondheidszorg tot energievoorziening, en van sociale zekerheid tot mobiliteit. Ook in de bedrijfscontext kan transitiemanagement worden toegepast op complexe veranderingsprocessen
Transformative Participation in Agro-Biodiversity Governance: Making the Case for an Environmental Justice Approach
Environmental justice has long been understood as dealing with the ex-post allocation of benefits and burdens. Such a conception raises two well-documented issues. First, theories of distributive justice are not suited for the study of the underlying conditions shaping decision-making on allocation. Second, given that different conceptions of morality and justice coexist in society, the conditions of a fair agreement tend to be better approached by defining the conditions of a fair decision-making process. Building on recent developments in environmental justice theory, this paper uses a tridimensional framework encompassing notions of distribution, recognition and representation to analyze ex-ante aspects of environmental justice. By using empirical examples of participatory governance mechanisms, it outlines a research framework attempting to bridge normative and instrumental approaches to environmental justice in natural resource management
Transformative Participation in Agrobiodiversity Governance:Making the Case for an Environmental Justice Approach
This paper makes the case for an environmental justice approach to the practice and study of participation and effectiveness in agrobiodiversity governance. It is argued that, in order to understand the conditions under which participation leads to improved outcomes, the concept has to be rethought, both from a political and a methodological perspective. This can be done by applying an ex-ante environmental justice approach to participation, including notions of distribution, recognition and representation. By exploring the approach through empirical examples of participation in biodiversity and environmental governance, a research framework is outlined, attempting to bridge normative and practical approaches to environmental justice, and tested on two cases of agrobiodiversity governance in Western Europe
