Northern Cyprus is a de facto state in the eyes of the international community. Its independence has been deemed illegitimate by the United Nations as it is seen as an occupied territory by Turkey. Therefore, Turkey is the only country in the world that recognizes the so-called Turkish Republic of Northern …

The Power to Flex project aims to promote the development of storage possibilities from sustainable energy sources. Hydrogen is opted to be a feasible energy carrier, which can also be stored for prolonged times without further losses and can be transformed into electricity and heat when needed. Producing …

The culture of fear seems to be increasingly embedded in today’s society, especially on highly social unequal countries, such as Brazil. The rise of the “condomínios fechados” (gated communities) on recent years expose how this fear shapes our cities. People are sold by the idea of isolating themselves …

Power-to-gas technologies are considered to be part of the future energy sys- tem, but their viability and applicability need to be assessed. Therefore, models for the viability of farm-scale bio-power-to-methane supply chains to produce green gas were analysed in terms of levelised cost of energy, energy …

A smart charging profile was implemented on 39 public charging stations in Amsterdam on which the current level available for electric vehicle (EV) charging was limited during peak hours on the electricity grid (07:00-08:30 and 17:00-20:00) and was increased during the rest of the day. The impact of …

Electric vehicles and renewable energy sources are collectively being developed as a synergetic implementation for smart grids. In this context, smart charging of electric vehicles and vehicle-to-grid technologies are seen as a way forward to achieve economic, technical and environmental benefits. The …

Within the Flexnode Plus project the long-term degradation characteristics of a proton exchange membrane (PEM) electrolyzer (5.5 kW, AC, 1 Nm3/h H2) and fuel cell (1.0 kW, DC, 0.9 Nm3/h) was experimentally tested. The electrolyzer unit was operated at various loads and pressures for approximately 750 …

One potential renewable energy resource is green gas production through anaerobic digestion (AD). However, only part of the biogas produced (up to 50-60%) contains the combustible methane; the remainder are incombustible gasses with the biggest being carbon dioxide. These gasses are often not used and …

Energy cooperatives are beginning to expand their role from stimulating small-scale electricity production to developing local energy systems, including cooperatively owned energy storage solutions. However, many technical, social and financial obstacles are encountered in this process. It is as yet …

Biogas is produced from biomass by means of digestion. Treated to so-called ‘green gas’, it can replace natural gas. Alternatively, biogas can be used to produce electrical power and heat in a combined heat power (CHP) installation. In 2014 global biogas production was only 1% of natural gas production. …
