Due to its low power density, PV requires much space, which could be a limiting factor for its future expansion. Placing PV on water has therefore become an interesting alternative siting solution. In this paper, the floating photovoltaic system is divided into four categories: fixed pile photovoltaic system, floating photovoltaic system, floating platform system and floating photovoltaic tracking system, and the principles, technologies, and future challenges of PV systems on water will be reviewed. Fixed pile PV is a kind of amphibious system with a column fixed under water yielding better safety. Floating PV systems are highly modular, easier to install, and more practical in countries with high population density and less available land. Another floating platform system builds upon a floating platform. Floating photovoltaic tracking systems have also been proposed to maximize the solar yield. When facing water level changes, PV systems need a mooring system that can adapt with the water level and avoid horizontal movement. Other challenges encountered with water PV are discussed and future research directions are presented.","PeriodicalId":423241,"journal":{"name":"Oxford Open Energy","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131949352","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Steinschneider","doi":"10.1093/ooenergy/oiad003","DOIUrl":"https://doi.org/10.1093/ooenergy/oiad003","url":null,"abstract":"\u0000 Rapid increases in global temperature are motivating governments to restructure the energy sector towards emissions-free electricity generation. One of the key factors affecting the viability of emissions-free power systems is the joint variability of renewable resources and drivers of energy demand across spatiotemporal scales. This study evaluates the impact of multi-scale hydroclimatic variability on the reliability of a zero-emissions power system in a case study of New York State (NYS), which recently passed the Climate Leadership and Community Protection Act (CLCPA) requiring zero-emissions electricity generation by 2040. We first analyze covariation between renewable energy generation and energy demand, including large-scale hydropower generation on the Great Lakes, and develop a stochastic generator to simulate an ensemble of plausible realizations of this joint variability. Using a simplified energy balance model of the NYS power system, we then quantify resource gaps across spatiotemporal scales that emerge under load and generation scenarios projected under the CLCPA. We focus on the intensity, duration, and frequency of these gaps, which will have to be filled with carbon-free, dispatchable resources not prescribed under the CLCPA. We show that the covariability between load and wind can lead to major short-term resource gaps, which is exacerbated by transmission constraints. We also show that long-duration hydropower droughts increase the likelihood of co-occurring renewable resource deficits and extended periods (weeks to months) of energy shortage. We conclude by discussing the implications of these results on the need for alternative, carbon-free, and dispatchable resources to support zero-emission, hydropower-reliant electric grids.","PeriodicalId":423241,"journal":{"name":"Oxford Open Energy","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123675752","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It established that the centralised energy governance of Semonkong seems less effective in solving conflicts compared to the decentralised energy governance of Ha-Makebe. Poor communication and lack of will to respond to community needs caused dissatisfaction and misunderstanding towards the centralised energy project. The study found that the decentralised energy project was more likely to be sustainable because it was characterised by community participation and engagement. The findings also revealed that the satisfaction of energy consumers results from a consistent supply of energy accompanied by responsiveness to community needs as opposed to a cheap inconsistent electricity supply. The implications are that the Semonkong plant’s sustainability is at risk, and the project may collapse unless the government of Lesotho, in the short term, engages with the community concerning its concerns.\u0000 Lay summary: This work assesses Lesotho’s two energy mini-grids to establish one with community involvement and participation in decision-making and sustainability prospects. The study established that the Ha-Makebe energy project was inclusive and inclined to community energy, democracy, and sustainability as it was swift in addressing simmering conflicts. In contrast, the Semonkong project was less consultative and lacked community involvement and participation in decision-making. As a result, its sustainability was at risk because it was slow to address community conflicts regarding the project.","PeriodicalId":423241,"journal":{"name":"Oxford Open Energy","volume":"326 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114381911","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In essence, such transformations are socio-technical change processes that require a combination of technological and social innovation. While it is widely acknowledged that ambitious climate and energy policies are needed to accelerate such transition processes, research and practise have largely focused on their importance for spurring technological innovation. In this research perspective, we argue that energy and climate policy making should pay more attention to social innovation as much needed additional puzzle piece for successful decarbonisation. Such social innovation is diverse, ranging from renewable energy cooperatives, to participatory incubation and experimentation, and crowdfunding as well as local electricity exchange. Based on a literature review that informed an EU policy dialogue bringing together policy makers, practitioners and researchers and followed up by a workshop with city administrations, twelve practical action points were co-created on how to better consider social innovation in energy and climate policy making in the EU (and beyond). We thereby hope to stimulate a broader discourse on the dual need for social and technological innovation for reaching climate-neutrality.","PeriodicalId":423241,"journal":{"name":"Oxford Open Energy","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127313212","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, many of these challenges can be converted into opportunities depending on how and when consumers decide to charge their vehicles. While there are currently multiple efforts worldwide investigating EV charging behaviour, these efforts measure the behaviour of EV early adopters and may not represent the actual behaviour of the mainstream consumer. The current study uses data from a survey with near a thousand Australian consumers to shed light on the potential similarities and differences between the charging needs and preferences of EV early adopters and mainstream consumers. We find that consumer groups vary in terms of charging needs, perceived access to residential charging, and acceptance of direct charging control and management by suppliers. Our conclusions point to (1) the need for campaigns that increase the awareness and understanding of residential EV charging by mainstream consumers, (2) the significant interest across all consumer groups in free workplace charging, which could together with residential demand management strategies leverage the use of solar energy for charging, and (3) the need for utility plans and management strategies that enhance the mainstream consumer sense of control over charging together with their perceived monetary savings.\u0000 Lay summary: This study analyses data from a survey with near a thousand Australian consumers to investigate potential similarities and differences between the charging needs and preferences of current electric vehicle (EV) owners and future mainstream consumers.

Over the last years, electrification of mobility has emerged as one of the major strategies that, accompanied with supporting measures, has led to rapid increase in the number of electric vehicles. Recently, hydrogen and hydrogen derivates as alternative fuels have also gained more interest and are considered to grow substantially in the near future as their production costs are decreasing. Here, we discuss the electric and hydrogen pathways towards zero-emission vehicles and sustainable mobility focusing on their benefits and challenges in the transition. We conclude that the future relevance of zero-emission vehicles will be heavily dependent on the policy framework, investments, and long-term visions.","PeriodicalId":423241,"journal":{"name":"Oxford Open Energy","volume":"163 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135158573","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
