Power-to-gas (P2G) technology is an emerging disruptive solution for renewable electricity integration and energy storage. Two significant challenges of its commercialization are the perceived risks associated to its scalability and the cost-benefit ratio of P2G versus other innovative energy storage technologies. Its emerging regulatory and business environment significantly limit the accuracy of the financial models, as well. In our research we have examined how inter-organizational networks and innovation management could contribute to the commercialization of the technology in spite of the above mentioned challenges. We performed action research between 2016-2019 at Hungarian technology developer startup Power-to-Gas Hungary Kft. Our research results show that dyad-level open innovation led to a significant opportunity to make new steps towards the commercialization of the disruptive technology. Because of the exploitative characteristics of the market environment and emerging regulatory framework we identified significant needs for complementary resources that would drive successful commercialization. We found that inter-organizational P2G innovation networks and their role in shaping further innovation and the establishment of regulatory sandbox models might be essential to overcome barriers of commercialization of this disruptive technology.

AbstractThe building sector in Sweden and Europe is a major energy consumer, accounting for around 40% of total energy use. It is a challenge to optimize available technical and social strategies for the fragmented construction industry. Professionals such as architects and different building engineers play a crucial role in the technology adoption process.This study aims to contribute to the understanding of how and why energy efficiency and saving measures are implemented by different professionals. The paper combines perspectives focusing the “the middle” in an organisation and social practice theory (SPT) to develop a framework which can be used to enhance the understanding of how and why energy efficiency measures are adopted in building processes. By combining these theoretical perspectives it is possible to arrive at a deeper understanding of what needs to be changed in the planning and management process to achieve a highly energy efficient renovation.

This research work investigates the possibilities of establishing renewable-based district heating (DH), including “hybrid district heating” (HDH) applications in a peripheral rural area of Hungary, the Bukkalja. HDH, or multi-source systems, use a reasoned combination of energy sources, which is still unusual practice in Eastern Europe. This particular Bukkalja region struggles with import dependency, energy poverty, and serious air pollution. Considering natural and social capabilities, potential sites for rural district heating developments were examined. Door-to-door field surveys, residential heat demand, GIS-based renewable energy potential calculations, detailed supply-demand and statistical analysis were applied to reveal DH development possibilities. Most of the results have a tight correlation with the relevant values of Pan-European Thermal Atlas (PETA 4.3), however, in case of suggestions, there are considerable differences. The outcomes also highlight that current biomass utilization far exceeds the sustainability limits within the area. The screening proves that the capabilities of seven rural settlements are suitable for DH developments. This investigation supports the decision-making process and its proposed projects could play a significant role in the local energy transition. This study underlines that rural DH developments could have the same relevance as similar projects in urban circumstances.

To ensure sustainable development, the generation expansion planning (GEP) should meet the electricity demands in the specify time horizon. The GEP will determine the type and capacity of generator units to meet with the minimum cost, required reserve margin and energy balance. In this paper, a GEP to minimize the cost by considering the high penetration hydro energy potential was carried out in Sulawesi electricity region. GEP optimization is done by finding the minimum total cost value that is done through WASP-IV. There were two approaches for conducting the optimization that are regional balanced and resources-based approaches. The effect of renewable energy plant, especially the hydro energy, can be seen through a resource-based scenario, where the generating units were priories installed close to the energy source location. On the other hand, the regional balanced approach would install the generating units close to the load center. This paper compared the results of regional balance to the resource-based scenarios. The results show that resource-based approach can achieve a renewable energy power plant mix of up to 30%. The regional balance scenario total costs were $ 9.83 billion in low projection electricity demand and $ 13.57 billion in high projection electricity demand. On the other hand, the resource-based scenario total costs were $ 9.54 billion in low projection electricity demand and $ 13.38 billion high projection electricity demand.

The concerns regarding the environmental damage require changes not only on how the energy is consumed but also how it is produced. The close relationship between energy use and the economic growth exposes the need for continuous monitoring of energy consumption, which cannot be achieved without assessing capital and operational costs from its conversion to end-use. Solar thermal systems offer few advantages over other renewable resources to meet the energy demand in the small-scale building sector. Solar-thermal technologies can play a leading role in meeting the decarbonisation targets set in Europe. The reports from the International Energy Agency (IEA) shows that solar heating has the potential to cover more than 16% of the low-temperature heat use in energy mix scenario. In Europe, this share might translate into 45% growth of the installed solar thermal capacity by 2020, setting a challenging target of 1 m2 of collector area installed per capita by 2020 and of 1.3 m2 by 2050. The main objective of the present work is to define a costing methodology able to estimate the capital cost of solar-thermal systems according to the system size and energy requirements of a specific residential building. The costing methodology consists of the derivation of a cost expression for each component by integrating thermodynamic and cost coefficients, adjusted for this kind of technology, and also taking into account real market data. The model was validated for a reference dwelling in Lisbon, with an occupation of 4 people with an estimated energy need of 2 037 kWh/year in terms of DHW. Results of the reference scenario show that is required at least 4 m2 of solar collector and the system cost ranges from 703.2€ per m2 to 763.2€ per m2, depending on the acceptable storage tank capacity.

An increase in household electricity prices has been taken place in the European Union in last years, which has been strongly influenced by the regulation component. This paper focuses on an empirical assessment of both supply-side and demand-side policies in the European Union over the period 2000-2015. More specifically, the analysis of the electricity industry liberalisation process and renewable energy support policies (from supply-side), as well as, energy taxes (from demand-side) has been developed in order to contribute to the present debate about the effect of these factors on household electricity prices. The results suggest that the liberalisation process has involved greater household electricity prices. Regarding solar photovoltaic energy support policies, the costs of quota obligation systems seem also to result in greater household electricity prices. However, energy taxes do not have a significant influence on these prices. Based on these results, recommendation actions are proposed for policy-makers.

The European Union has being developing its Energy and Enviornmental policy along the last 30 years. Recent European Commision communications confirm the leadership of European Union on reducing pollutant gases emissions and technological change towards climate neutral economy. This study assessess the efficiency of European Energy Policy from a Modern Portfolio Theory perspective. The proposal studies the disaggregated European power portfolio: to make a more exhaustive analysis, focusing individually on each European country along the period 1990-2015. The efficiency of the Energy and Environmental Policy of each Member State is calculated measuring their distance to the power generation efficient frontier. The quadratic optimization model used by MPT is complemented by a cluster analysis of European Member States, in order to be able to observe country behaviour tendencies: regarding the application of their energy and environmental policies without overlooking the efficiency of that implementation. Results stand out that France, Slovakia and Sweden belong to the “leader” efficient cluster for the considered period. In turn, Denmark, Germany, Greece and Italy show a high consistence in the application of their energy and environmental policies along the considered period, as they moved upwards during that period.

District heating (DH) is considered an important component in a future highly renewable European energy system. With the turn towards developing 4th generation district heating (4GDH), the integral role of district heating in fully renewable energy systems is emphasized further. Norway is a country that is expected to play a significant role in the transition of the European energy system due to its high shares of flexible hydropower in the electricity sector. While the country is moving towards electrification in all sectors and higher shares of variable renewable electricity generation, district heating could potentially decrease the need for electric generation and grid capacity expansion and increase the flexibility of the system. In this paper we investigate the role of 4GDH in a highly electrified future Norwegian energy system. A highly electrified scenario for the Norwegian energy system is constructed based on a step-by-step approach, implementing measures towards electrification and expansion of renewable electricity generation. Then, a 4GDH scenario is constructed for the purpose of analysing the role of 4GDH in a highly electrified hydropower based energy system. EnergyPLAN is used for simulation. Results show that an expansion of 4GDH will increase the total system efficiency of the Norwegian energy system. However, the positive effects are only seen in relation to the introduction of efficiency measures such as heat savings, more efficient heating solutions and integration of low-temperature excess heat. Implementation of heat savings and highly efficient heat pumps in individual based heating systems show a similar effect, but does not allow for excess heat integration. In the modelled DH scenario, the introduction of large heat storages has no influence on the operation of the energy system, due to the logic behind the EnergyPLAN model and the national energy system analysis approach chosen, and thus the effect of implementing 4GDH may be underestimated.

In future UK energy scenarios with a high level of electrification, a large share of electricity is expected to be generated from renewable sources. To accommodate the variability of renewable generation, flexibility in the network is vital. An important flexibility option is grid scale electricity storage. A simulation is made of the electricity system with variable renewable generation, electricity storage and flexible high carbon generators, assumed to be gas CCGT, for various UK scenarios. The simulation uses historical hourly meteorology to drive models of demand and renewable variation, and the consequent input/output operation of storage and dispatchable generation to balance differences between demand and renewables. A marginal cost method is devised to calculate the storage, renewable and dispatching capacity and operational costs incurred in each hour. These cost structures can form a transparent economic base for informing market design and setting prices for use in energy system models. Results show that while marginal costs for renewable generation are relatively low, reliance on battery storage for backup particularly during peak periods can result in high electricity prices and without a significant increase in projected fossil fuel or carbon prices, traditional high carbon electricity generators will still be cheaper to operate. This work will be used to analyse the interaction between district heating with thermal energy storage and heat pumps, and the electricity system.
