The goal of achieving a zero-emission energy system by 2050 requires accurate energy planning to minimise the overall cost of the energy transition. Long-term energy models based on cost-optimal solutions are extremely dependent on the cost forecasts of different technologies. However such forecasts are inherently uncertain. The aim of the present work is to identify a cost-optimal pathway for the Italian energy system decarbonisation and assess how renewable cost scenarios can affect the optimal solution. The analysis has been carried out with the H2RES model a single-objective optimisation algorithm based on Linear Programming. Different cost scenarios for photovoltaics on-shore and off-shore wind power and lithium-ion batteries are simulated. Results indicate that a 100% renewable energy system in Italy is technically feasible. Power-to-X technologies are crucial for balancing purposes enabling a share of non-dispatchable generation higher than 90%. Renewable cost scenarios affect the energy mix however both on-shore and off-shore wind saturate the maximum capacity potential in almost all scenarios. Cost forecasts for lithium-ion batteries have a significant impact on their optimal capacity and the role of hydrogen. Indeed as battery costs rise fuel cells emerge as the main solution for balancing services. This study emphasises the importance of conducting cost sensitivity analyses in long-term energy planning. Such analyses can help to determine how changes in cost forecasts may affect the optimal strategies for decarbonising national energy systems.

This report aims to summarise the status of the European hydrogen market landscape. It is based on the information available at the European Hydrogen Observatory (EHO) initiative the leading source of data on hydrogen in Europe exploring the basic concepts latest trends and role of hydrogen in the energy transition. The data presented in this report is based on research conducted until the end of September 2024. This report contains information on current hydrogen production and trade distribution and storage end-use cost and technology manufacturing as of the end of 2023 except if stated otherwise in Europe. A substantial portion of the data gathering was carried out within the framework of Hydrogen Europe's efforts for the European Hydrogen Observatory. Downloadable spreadsheets of the data can be accessed on the website: https://observatory.clean-hydrogen.europa.eu/. The production and trade section provides insights into hydrogen production capacity and production output by technology in Europe and into international hydrogen trade (export and import) to and between European countries. The section referring to distribution and storage presents the location and main attributes of operational dedicated hydrogen pipelines and storage facilities as well as publicly accessible and operational hydrogen refuelling stations in Europe. The end-use section provides information on annual hydrogen consumption per end-use in Europe the deployment of hydrogen fuel cell electric vehicles in Europe the current and future hydrogen Valleys in Europe and the leading scenarios for future hydrogen demand in Europe in 2030 2040 and 2050 by sector. The cost chapter offers a comprehensive examination of the levelised cost of hydrogen production by technology and country. This chapter also gives estimations of renewable hydrogen break-even prices for different end-use applications in addition to electrolyser cost components by technology. Finally a chapter on technologies manufacturing explores data on the European electrolyser manufacturing capacity and sales and the fuel cell market.

To address the global climate crisis maritime logistics are undergoing a transition away from fossil-based energy sources. The transition is envisaged to be both green (involving renewables) and digital (involving various kinds of digitalization). Much of the hope rests on the new hydrogen economy involving the build-up of infrastructure for hydrogen-derived alternative fuels such as methanol and ammonia. Indeed the new hydrogen economy is often portrayed as set to revolutionize maritime transport. The hope behind the hype reflects a belief in the performativity of hypes: some technological phenomenon will eventually materialise in innovation and business practices. In this paper we critically analyse the current hydrogen hype in the field of Finnish maritime logistics as a paradigmatic case of performative techno-optimism. Based on causal network analysis and thematic analysis of expert interviews and workshop data we argue that the phenomenon of performative techno-optimism is more nuanced than hitherto presented in the related literature. We showcase a variety of stances along a spectrum ranging from radical optimism to radical pessimism. Furthermore our causal network analysis indicates that the current green and digital transition of maritime transport is caught in a systemic catch-22: transitioning to alternative fuels in maritime logistics faces a lock-in of between overly cautious demand for alternative fuels leading to overly cautious investment in supply which only secures the modest demand. Finally our thematic analysis of techno-optimist stances suggests the following two major ways out of the systemic dilemma: large-scale technological innovations and global regulatory solutions.

Hydrogen Valley represents localised ecosystems that enable the integrated production storage distribution and utilisation of hydrogen to support the decarbonisation of the energy system. However planning such integrated systems necessitates a detailed evaluation of their interconnections with variable renewable generation sector coupling and system flexibility. The novelty of this work lies in addressing a critical gap in system-level modelling for Hydrogen Valleys by introducing an optimization-based framework to determine their optimal configuration. This study focuses on the scenario-based multiobjective design of local hydrogen energy systems considering renewable integration infrastructure deployment and sector coupling. We developed and simulated three scenarios based on varying hydrogen pathways and penetration levels using the EnergyPLAN model implemented through a custom MATLAB Toolbox. Several decision variables such as renewable energy capacity electrolyser size and hydrogen storage were optimised to minimise CO₂ emissions total annual system cost and critical excess electricity production simultaneously. The findings show that Hydrogen Valley deployment can reduce CO₂ emissions by up to 30 % triple renewable penetration in the primary energy supply and lower the levelized cost of hydrogen from 7.6 €/kg to 5.6 €/kg despite a moderate increase in the total cost of the system. The approach highlights the potential of sector coupling and Power-to-X technologies in enhancing system flexibility and supporting green hydrogen integration. The outcome of our research offers valuable insights for policymakers and planners seeking to align local hydrogen strategies with broader decarbonisation targets and regulatory frameworks.

Many countries of the Global South struggle to achieve inclusive growth paths despite investment in the exploitation of rich resources. Resource-based industrialization literature stresses the potential for achieving broader development effects via the development of production linkages with local enterprises. The focus lies on market-driven outsourcing dynamics that foster linkage development such as efficiency location-specific knowledge and technology and scale complexity. However little is known about the opportunity space for both policy making and local firms to create these linkages. To address this issue we incorporate the concept of change agency stemming from the path development literature into the discussion on production linkages to show how both (local) firm agency and system-level agency can achieve linkage creation for inclusive path transplantation. We illustrate the framework by scrutinizing the potential inclusion of solar energy companies in Namibia’s emerging green hydrogen economy. The study finds that while the potential for renewable energy companies in Namibia to participate in the value chain is limited an integrated bundle of measures relying on firm- and system-level agency could address peripheral contextual factors overcome entry barriers and leverage further potential for linkage creation in the solar energy sector: mobilizing the local workforce fostering inter-firm cooperation leveraging local advantages creating knowledge institutions enhancing the regulatory framework upgrading infrastructure and enforcing local content regulations.

Importing renewable energy to Europe may offer many potential benefits including reduced energy costs lower pressure on infrastructure development and less land use within Europe. However open questions remain: on the achievable cost reductions how much should be imported whether the energy vector should be electricity hydrogen or derivatives like ammonia or steel and their impact on Europe’s infrastructure needs. This study integrates a global energy supply chain model with a European energy system model to explore net-zero emission scenarios with varying import volumes costs and vectors. We find system cost reductions of 1-10% within import cost variations of ± 20% with diminishing returns for larger import volumes and a preference for methanol steel and hydrogen imports. Keeping some domestic power-to-X production is beneficial for integrating variable renewables leveraging local carbon sources and power-to-X waste heat. Our findings highlight the need for coordinating import strategies with infrastructure policy and reveal maneuvering space for incorporating non-cost decision factors.

This article explores how the implementation of solar PV and transportation infrastructure – grid or hydrogen pipeline – has implications for various aspects of security cooperation and geopolitical powershifts. Highlighting the emerging intra-European green hydrogen pipeline project H2Med we examine the Portuguese geopolitical ambitions related to their geographical advantage for solar PV energy production. Using media and document analysis we identified two main axes of solar PV implementation in Portugal – one centered on resilience and one on exports – and further explored underlying and resulting tensions in neighboring countries’ energy strategies and cleantech innovation policies. Our analysis revealed that policy prioritizations in solar PV diffusion result in unequal effects on resilience energy security and power shifts. In particular solar PV implementations such as individual to local or regional grid-based ‘prosumption’ setups result in notably different geopolitical effects compared to large-scale solar PV to green hydrogen-production for storage and export. Thereby emerging possibilities of storage and long-distance trade of renewable energies have more significant implications on geopolitics and energy security than what is typically recognized.
