“…-One feasible way to meet EU long term large scale energy storage requirements is through storage in chemical bonds [34], the Power to Gas (P2G) scheme, converting RE electricity into gas. As compared with flywheels, batteries, compressed air (CAES) and pumped hydro, chemicals offer long-term and large-scale energy storage.…”

Summary. -The need for storage of renewable energy (RE) generated by photovoltaic, concentrated solar and wind arises from the fact that supply and demand are ill-matched both geographically and temporarily. This already causes problems of overcapacity and grid congestion in countries where the fraction of RE exceeds the 20% level. A system approach is needed, which focusses not only on the energy source, but includes conversion, storage, transport, distribution, use and, last but not least, the recycling of waste. Furthermore, there is a need for more flexibility in the energy system, rather than relying on electrification, integration with other energy systems, for example the gas network, would yield a system less vulnerable to failure and better adapted to requirements. For example, long-term large-scale storage of electrical energy is limited by capacity, yet needed to cover weekly to seasonal demand. This limitation can be overcome by coupling the electricity net to the gas system, considering the fact that the Dutch gas network alone has a storage capacity of 552 TWh, sufficient to cover the entire EU energy demand for over a month. This lecture explores energy storage in chemicals bonds. The focus is on chemicals other than hydrogen, taking advantage of the higher volumetric energy density of hydrocarbons, in this case methane, which has an approximate 3.5 times higher volumetric energy density. More importantly, it allows the ready use of existing gas infrastructure for energy storage, transport and distribution. Intermittent wind electricity generated is converted into synthetic methane, the Power to Gas (P2G) scheme, by splitting feedstock CO2 and H2O into synthesis gas, a mixture of CO and H2. Syngas plays a central role in the synthesis of a range of hydrocarbon products, including methane, diesel and dimethyl ether. The splitting is accomplished by innovative means; plasmolysis and high-temperature solid oxygen electrolysis. A CO2-neutral fuel cycle is established by powering the conversion step by renewable energy and recapturing the CO2 emitted after combustion, ultimately from the surrounding air to cover emissions from distributed source. Carbon Capture and Utilisation (CCU) coupled to P2G thus creates a CO2-neutral energy system based on synthetic hydrocarbon fuel. It would enable a circular economy where the carbon cycle is closed by recovering the CO2 emitted after reuse of synthetic hydrocarbon fuel. The critical step, technically as well as economically, is the conversion of feedstock CO2/H2O into syngas rather than the capture of CO2 from ambient air.

Concerns related to climate change and global warming caused by anthropogenic activities and in particular fossil energy use have been increasing lately. Air pollution and volatile conventional fuel prices emphasize the need to transition the energy system towards very high shares of renewables. 100% renewable energy systems have been analyzed by many researchers starting from 1975. This bibliometric analysis reviews more than 600 scientific articles in which 100% renewable energy systems were surveyed. This study uses tools of bibliometric analysis, based on publication databases and data mining, together with review elements to understand the current status and trend of 100% renewable energy systems research. The focus of results is on quantitative parameters relating to number and publication types, collaborative links among authors, institutions, and countries. Collaborative networks provide the significant concentration of published papers within organizations and co-authorships globally. The results reveal that the dominant organizations and thus number of published papers are from Europe and the USA; however, almost all the established research organizations in the field of energy system analysis are not active in the field of 100% renewable energy systems analyses. The journals Energy and Applied Energy have the most articles, and accordingly the most citations. EnergyPLAN and LUT Energy System Transition Model have been the most active tools used to analyze 100% renewable energy systems according to numbers of articles and received citations. The topic of modeling approach indicates the term 'Energy System' has the highest frequency due to its emergence in the articles. This research provides a holistic overview on the more than four decades of research, and it reveals dynamics within the field with a compound annual growth rate of articles of 26% for the 2010s, the trend of publications, and author growth that comprises now almost 1400 authors with articles in the field.

The stability of energy generation is crucial for the functioning of every country. Currently, the EU policy is moving towards becoming independent of fossil energy sources, which can be replaced with sources that are not exhaustible, for example, energy from the sun. Public awareness of renewable energy is increasing. People are willing to invest in natural solutions. However, planning large photovoltaic farm projects is difficult due to complex location requirements. The study aimed to analyse the interferences/barriers to be considered when searching for a suitable location to install a photovoltaic farm. The analysis was conducted for the territory of Poland. The study used a literature and local legislation query and the Delphi method. The Delphi method identified the most important interferences from the investor’s perspective. Eleven interferences have been identified, classified into legal, spatial, technical, social, and financial groups. Several are locally determined and only exist in selected locations (e.g., technical determinants of the power grid condition, etc.). In contrast, others are unitary (e.g., concerns about the impact of PV on human health, etc.). The decision-makers are aware of the existing interferences/barriers, and the proposed administrative, legal, and technical solutions marginally mitigate barriers. System solutions are recommended, allowing an easier way to find a suitable location for a PV system.
