“…The reported data by NASA, however, are at altitude of 50 m from earth surface. Since wind speed varies with altitude, the estimated hourly wind speeds should be scaled properly to the height of selected wind turbine according to Equation (7) [40]:…”

Synthetic Diesel Production as a Form of Renewable Energy Storage

2018

View full text Add to dashboard Cite

Production of synthetic hydrocarbon fuels as a means for renewable energy storage has gained attention recently. Integration of solid oxide co-electrolysis of steam and carbon dioxide with the Fischer-Tropsch process to transform renewable electricity into Fischer-Tropsch diesel is one of the promising suggested pathways. However, considering the intermittency of produced renewable electricity such integration will have a low capacity factor. Besides, locating a reliable source of carbon dioxide near the installed integrated system may prove to be difficult. A novel integration for production of Fischer-Tropsch diesel from various renewable sources is suggested in this study. The proposed integrated system includes solid oxide electrolysis, entrained gasification, Fischer-Tropsch process and an upgrading system. Gasification is assumed to have a continuous operation which increases capacity factor of the integrated system. Carbon dioxide supplied via gasification of biomass provides a reliable source for on-site co-electrolysis. Technical capabilities of the proposed integrated system examined by investigating performance in relation with electricity, and diesel demand of four different European cities. Results show that the proposed system is capable of supplying Fischer-Tropsch diesel of between 0.9-32% of the annual diesel demand for road transportation respective to the location of installation, with a high emission savings (around 100%). Cost of produced diesel is not competitive with conventional diesel for all cases, even when all the other by-products were assumed to be sold to the market.

“…However, it should be noted that offshore wind is generally associated with higher yields, and that the global industry is expanding (International Renewable Energy Agency 2016). Though at present there is a relative lack of offshore wind speed data to allow for a geospatial assessment of offshore wind potential in Africa (Mentis et al 2015), it is clear that this resource is an asset to be considered by coastal countries (see for instance a feasibility assessment for a site in Nigeria (Effiom et al 2016)). …”

Energy in Africa Challenges and Opportunities SpringerBriefs in EnergySpringerBriefs in Energy presents concise summaries of cutting-edge research and practical applications in all aspects of Energy. Featuring compact volumes of 50-125 pages, the series covers a range of content from professional to academic. Typical topics might include:• A snapshot of a hot or emerging topic • A contextual literature review • A timely report of state-of-the art analytical techniques • An in-depth case study • A presentation of core concepts that students must understand in order to make independent contributions.Briefs allow authors to present their ideas and readers to absorb them with minimal time investment. Briefs will be published as part of Springer's eBook collection, with millions of users worldwide. In addition, Briefs will be available for individual print and electronic purchase. Briefs are characterized by fast, global electronic dissemination, standard publishing contracts, easy-to-use manuscript preparation and formatting guidelines, and expedited production schedules. We aim for publication 8-12 weeks after acceptance.Both solicited and unsolicited manuscripts are considered for publication in this series. Briefs can also arise from the scale up of a planned chapter.

“…The wind turbines were assumed as 2 MW wind turbines with a height of 120 m (blade included) and a rotor diameter (D) of 90 m. The number of wind turbines that can be installed on the site was determined by the geographical area of each site. To reduce the array losses and improve energy efficiency, at least a distance of 5-times the rotor diameter (5D) and approximately a 450-m spacing between two turbines is needed [26,27]. Therefore, we used the wind power potential layer's mesh, whose size is 500 mˆ500 m. The locations of the wind turbine were determined as the geometric center of each mesh.…”

GIS-Based Approach for Municipal Renewable Energy Planning to Support Post-Earthquake Revitalization: A Japanese Case Study

et al. 2016

View full text Add to dashboard Cite

Following a regional-level study conducted in Fukushima Prefecture, Japan (Wang et al., 2014 [1]), this paper presents an approach for municipal renewable energy planning and its experimental application in a Japanese municipality using a Geographic Information System (GIS). The proposed approach is comprised of local issue identification, renewable energy potential evaluation and visualization, site comparison and scenario analysis. GIS was used to analyze and visualize solar, wind and biomass (forest and agriculture residue) potential within Kawamata Town, Fukushima, Japan. According to local conditions, all potential sites were coded and then compared based on different criteria, such as solar radiation, wind speed, slope and land uses, among others. In the scenario analysis section, two scenarios, "renewable energy prioritized" and "evacuation area prioritized", were adopted and compared. The scenarios are altered in terms of placement and the number of renewable energy facilities inside and outside evacuation areas within the town. The results generated through the proposed approach can provide information on local potentials of renewable energy resources, as well as renewable energy development alternatives at the municipal level. They can be used in the interactive dialogue for the municipal renewable energy planning process, to help to fulfill the municipality's post-earthquake energy developmental vision.
