Occurrence and fate of methane leakage from cut and buried abandoned gas wells in the Netherlands

Methane leakage caused by well integrity failure was assessed at 28 abandoned gas wells and 1 oil well in the Netherlands, which have been plugged, cut and buried to below the ground surface (≥3 mbgl). At each location, methane concentrations were thoroughly scanned at the surface. A static chamber setup was used to measure methane flow rates from the surface as well as from 1 m deep holes drilled using a hand auger. An anomalously high flow rate from 1 m depth combined with isotopic confirmation of a thermogenic origin revealed ongoing leakage at 1 of the 29 wells (3.4%), that had gone undetected by surficial measurements. Gas fluxes at the other sites were due to shallow production of biogenic methane. Detailed investigation at the leaking well (MON-02), consisting of 28 flux measurements conducted in a 2 × 2 m grid from holes drilled to 1 and 2 m depth, showed that flux magnitude was spatially heterogeneous and consistently larger at 2 m depth compared to 1 m. Isotopic evidence revealed oxidation accounted for roughly 25% of the decrease in flux towards the surface. The estimated total flux from the well (443 g CH4 hr−1) was calculated by extrapolation of the individual flow rate measurements at 2 m depth and should be considered an indicative value as the validity of the estimate using our approach requires confirmation by modelling and/or experimental studies. Together, our findings show that total methane emissions from leaking gas wells in the Netherlands are likely negligible compared to other sources of anthropogenic methane emissions (e.g. <1% of emissions from the Dutch energy sector). Furthermore, subsurface measurements greatly improve the likelihood of detecting leakage at buried abandoned wells and are therefore essential to accurately assess their greenhouse gas emissions and explosion hazards.

Reflections on the role of energy network companies in the energy transition

Background Energy network companies are commonly attributed the public task to help society in becoming greener in the domain of energy. This extra public task has high costs and comes with high uncertainties. It may also compete with existing public tasks of network companies. When network companies are involved in local green initiatives, they encounter dilemmas and need to arrange trade-offs among multiple public values. It may also compete with existing tasks of network companies. Therefore, these network companies can face dilemmas when involved in local green initiatives. The aim of this paper is to reflect on the role of energy network companies in the face of these dilemmas. What is the role of energy network companies in coping with conflicting public values when helping local initiatives that create a greener energy system? Methods We answer this question via an essay that reflects on existing research in the Dutch energy sector. Our answer is derived from the fields of law, politics, policy, economics and engineering about the role of network companies. Results and discussion We argue that these five perspectives leave the role of energy network companies in the energy transition under-articulated. Our additional answer is based on our own empirical research that focuses on how network companies currently deal with dilemmas between multiple public tasks. Conclusion We provide an analytical framework that enables a way of understanding the role of network companies in the struggle with dilemmas and raise several points of discussion to that might refocus efforts of researchers and practitioners to elucidate the role of network companies.

Public-private or private-private energy partnerships? Toward good energy governance in regional and local green gas projects

An important avenue toward a proper ‘energy transition’ through regional and local projects is for government to collaborate with private sector organizations. In the energy sector, these latter organizations are often already involved in private-private partnerships for collaboration toward energy transition. This article focuses on the energy governance question whether in fact some of these forms of collaboration actually are about public governance, as they effectively lean on government involvement. This seems to be the case in the construction of biogas infrastructures for the production and distribution of green gas. This contribution discusses, on the basis of the case ‘Biogas grid Noordoost Fryslân’, if such collaboration should in fact be labeled as public-private partnership (PPP). In the energy governance discourse, this issue is important because in the organization of PPP, the public interest of energy transition comes with specific normative safeguards, originating in public law. This article provides a legal normative assessment on the basis of a specific case, the Biogas grid Noordoost Fryslân. The relevant empirical data on this case is gathered by a document study, including research reports, policy plans, project documents, and by interviews. Experts from the Dutch energy sector were face-to-face interviewed by a semi-structured questionnaire. The analysis uses the concept of PPP in relation to public authority. On the basis of a confrontation between the results from literature and from the results of empirical case study of a biogas grid in the Dutch region Noordoost Fryslân, we conclude that governmental influence can take a ‘disguised’ form by ‘quasi’ private organizations, with major normative consequences for the mode of sustainable energy governance. Administrative law in particular poses (binding) criteria for safeguarding public interests, such as on transparency, relevant also to the mode of governance applied in the promotion of renewable energy. Public standards for governance of renewable energy projects have to be sufficiently safeguarded, as regards their form and content of steering, while at the same time retaining the advantages, which ensue from private party involvement within PPP.

Divorce comes at a price: An ex ante welfare analysis of ownership unbundling of the distribution and commercial companies in the Dutch energy sector

Vertical unbundling in the electricity sector is a hot political topic in the European Union. The European Commission has decided that the ownership unbundling of transmission networks from other stages in the value chain is the most effective way to ensure fair network access and infrastructure investment. While this European unbundling debate has not ended yet and most countries still do not have an independent transmission system operator (TSO), the Dutch government has already taken one step further. In 2008, it decided that distribution companies should be completely separated from commercial activities that are part of the same holding (generation, trade and supply). This governmental decision has been fiercely debated. Although the goal is to improve competition as well as security of supply, these benefits are uncertain. Nevertheless, it is certain that ownership unbundling comes at a cost. In this paper we present an ex ante cost-benefit analysis of the Dutch unbundling act. We conclude that it is unlikely that this act is welfare enhancing: divorce comes at a price.

Implementing transition management as policy reforms: a case study of the Dutch energy sector

Proposals to alter large-scale socio-technical systems through government actions in order to promote goals such as sustainability are highly uncertain policy projects. What is being proposed is the replacement of specific elements of existing policy ‘mixes’—the goals and means—by others, in the expectation of avoiding counterproductive or sub-optimal policy outcomes. While laudable, such efforts are fraught with risks; including the possibility of the creation of sub-optimal policy mixes or of failed reform efforts with resulting poor outcomes. This article develops a model and typology of policy regime change processes and outcomes following Thelen and others in arguing that complex policy mixes typically emerge through one or more of four processes, ‘drift’, ‘conversion’, ‘layering’ and ‘replacement’, and that the expected outcomes of these different processes in terms of their ability to meet initial expectations are linked to the manner in which policy goals and means are (or are not) combined in a consistent, coherent and congruent fashion. This propensity is illustrated through examination of the case of energy transition management as practiced in the Netherlands.

Multi-Regime Interactions in the Dutch Energy Sector: The Case of Combined Heat and Power Technologies in the Netherlands 1970–2000

This article is about multi-regime interactions in energy sectors. Multi-regime interactions are interactions between fairly well defined and separated systems of production, intermediation and use. It is argued that multi-regime interactions have been underexposed in previous innovation literature, yet it is hypothesized that multi-regime interactions are critically important for understanding transition processes, and in particular for current transitions in European energy sectors. Based on a case study on combined heat and power (CHP) in the Netherlands, a typology is developed of four types of interaction: competition, symbiosis, integration and spill over.

Performance of the Dutch Energy Sector based on energy, exergy and Extended Exergy Accounting

The performance of the Dutch Energy Sector is analyzed using the Standard Exergy Analysis as well as Extended Exergy Accounting (EEA) method. Performance indicators based on energy, exergy and cumulative exergy consumption (CExC) are evaluated for three subsectors: exploitation, transformation, and distribution of energy. It is shown that performance indicators based on CExC are much lower than those based on energy and exergy concepts. The EEA method is applied for analysis of four branches: cokeries and refineries, refineries, central electricity production, and distribution and decentral electricity production. The EEA method originally proposed by Sciubba is modified by evaluating the cost-to-exergy conversion factor from the monetary value and CExC of the feedstock. It was found that the monetary equivalent of extended exergy is higher than the respective product sales. Finally, it is shown that performance indicators of selected energy branches based on extended exergy are much lower than those based on the CExC.

96/03454 - Major changes ahead for Dutch energy sector

Increases in energy-use efficiency have made impressive contributions to both economy and environment over the last two decades, but the rate of improvement has slowed and energy-efficiency continues to be a controversial subject. We explore the genesis and character of the energy-efficiency debate and assess the roles of market forces, government intervention, and technological innovation in determining future progress. We discuss the prognosis for utility energy-efficiency programs, which are imperiled by the current trend to utility deregulation. We note that decreasing energy prices have weakened the earlier economic stimulus to energy efficiency and discuss the strong driving force that has arisen from environmental issues. We examine the proposition that innovation stimulated by R&D investment has been a key ingredient in the development of energy-efficient technologies and assert that the continuing development of a knowledge base to assure future innovation requires a strong government/private-sector partnership.
