“…In this scenario, the avoided electricity production from fossil fuel reaches 62.2 GWh. Using an overall electricity emission factor of diesel generators of 0.75 kg CO 2 per converted kWh [17], the avoided greenhouse gas emissions are 46,671 ton CO 2 .…”

a b s t r a c tIn this article different scenarios are analysed with the objective of increasing the penetration of renewable energies in the energy system of S. Vicente Island in Cape Verde. An integrated approach is used to analyse the electricity and water supply systems. The H 2 RES model, a tool designed to simulate the integration of renewable sources and hydrogen in the energy systems of islands or other isolated locations, is applied.There is no other source of fresh water available to supply the population of S. Vicente, apart from desalinated seawater. The electricity supply system of this Island is based on fossil fuel and wind. S. Vicente has important wind resources that are not fully used because of its intermittent nature. The topography of this Island is relatively uniform, with the exception of Mont Verde, a 774 m high mountain located in its centre, which could be suitable for pumped hydro storage.The present analysis incorporates the possibility of using pumped hydro as a storage technique to increase the penetration of renewable energy sources, using desalinated seawater.The results show that is possible to have more than 30% of yearly penetration of renewable energy sources in the electricity supply system, together with more than 50% of the water supplied to the population produced from wind electricity.

“…The conventional remedial strategy is to plug the supply gap providing alternative capacity, known as spinning reserve [5]. Among the solutions devoted to RES electric grid integration, it is worth mentioning the use of high capacity energy storage to save the produced energy surplus and postponing the energy surplus delivery [6,7], or combining renewable energy sources with complementary intermittencies [8].…”

“…The transient model and the simulations were performed in the TRNSYS environment [22] supported by the in-house made types of the biomass furnace and reciprocating steam engine and the STEC component model library [23]. The software TRNSYS was selected as it is a well-known instrument to model complex energy systems, as demonstrated by several studies appeared in the open literature which mostly deal on RES applications in a few fields like small-islands stand alone power systems [7,24], or, more related to the present paper, on CSP field simulations [25,26], TES behaviour in solar trough plants [27] and matching to a hotel end-user [15].…”

Abstract:The present work investigates the matching of an advanced small scale Combined Heat and Power (CHP) Rankine cycle plant with end-user thermal and electric load. The power plant consists of a concentrated solar power field co-powered by a biomass furnace to produce steam in a Rankine cycle, with a CHP configuration. A hotel was selected as the end user due to its high thermal to electric consumption ratio. The power plant design and its operation were modelled and investigated by adopting transient simulations with an hourly distribution. The study of the load matching of the proposed renewable power technology and the final user has been carried out by comparing two different load tracking scenarios, i.e., the thermal and the electric demands. As a result, the power output follows fairly well the given load curves, supplying, on a selected winter day, about 50 GJ/d of thermal energy and the 6 GJ/d of electric energy, with reduced energy dumps when matching the load.

“…Tourism usually represents a large share of islands' total income, i.e., a conflict between tourism and RES may exist, although [20][21][22][23] suggest that this does not necessarily have to be the case. There is a surprising paucity of analysis both on the environmental impacts of RES in islands (with the exception of María and Tsoutsos [12]) and, more importantly, on the environmental problems that can be alleviated through the use of RES.…”

In Egypt, Hydropower sector plays a key role in Climate smart technological solutions to mitigate and adapt climate change. Egypt intends to replace the existing Assiut barrage in Nile River with a new one incorporating a hydropower plant. The technical and economical feasibility of the rehabilitation of the existing barrage including the installation of a low head hydropower plant of about 32 MW is proved. The electricity produc tion of about 250 GWh annually is planed. The optimization of hydropower output will be achieved through mitigation of project-related environmental and social impacts. The implementation of measures to predict, monitor and mitigate or avoid construction and operation impacts is planned. This Paper sets out information relating to the contribution of Hydropower plant of New Assiut Barrage Project towards Adaptation and sustainability options. The Paper assesses the socio-economic and environmental impact of the project, the indicators applicable to the scheme / community in question, and details of the method used to diagnose and monitor social-environmental performance. Where applicable, the diagnostic for the community must be presented separately from that carried out for the scheme. The Paper concludes that the Hydropower plant of the New Assiut Barrage Project has very promising positive aspects in relation to climate change mitigation and adaptation and sustainable development in Egypt.
