Abstract The knowledge of wind speed characteristics of a region is among the most important aspect of wind turbines utilization for electricity production and assessing the cost of power generation. The wind spectrum and the wind power density for the city of Chabahar located in the southeastern part of Iran were modeled using Weibull distribution and power law estimation. An empirical approach was used to determine the shape parameter, k, and the scale parameter, c, of Weibull distribution function at different heights from 2014 to 2016 during two years period. Wind characteristics in Chabahar were extensively analyzed along with assessing the effects of parameters such as air humidity and temperature, surface roughness, turbulence, and wind velocity durations. The amount of wind power that can be produced by installation of eight wind turbines with different powers ranging from 2.5 kW to 8 MW at Chabahar were investigated. Additionally, the annual capacity factor for each turbine was determined. A wind-hydrogen system was considered in the analysis for evaluating the hydrogen production ability from wind energy in the station at Chabahar. The highest amount of hydrogen production was related to Vestas V164 with the yearly value of 194.36 ton-H2.

Main aim of this study is to investigate annual wind power output, annual hydrogen production quantity and hydrogen production cost of wind-hydrogen energy system in the Pinarbasi-Kayseri region in Turkey which has remarkable wind potential in the central region of Turkey. Turkish State Meteorological Service (TSMS) measured the value of mean wind speed of Pinarbasi as 3.67 m/s above 10m ground between 2000 and 2006 years. In this study, three different hub heights (50m, 80m and 100m) were considered, and so the measured mean wind speed at 10m was extrapolated to considered heights and annual wind power output was calculated. Four different turbine rated powers (800kW, 900kW, 2000kW and 3000 kW) and two different electrolyser powers (120kW and 40kW) for hydrogen production were assumed. Levelised cost of electricity method was used in order to determine the cost analysis of wind energy and hydrogen production. The results of this study bring out clearly the variation of potential of hydrogen production and cost with wind speed, wind turbine hub height and wind turbine rated power and electrolyser power.

The Japan Atomic Energy Agency (JAEA) is conducting research and development on nuclear hydrogen production using High Temperature Gas-cooled Reactor and thermochemical water-splitting Iodine-Sulfur (IS) process aiming to develop large-scale hydrogen production technology for “hydrogen energy system”. In this paper, the present status of R&D on IS process at JAEA is presented which focuses on examining integrity of such components as chemical reactors, separators, etc. Based on previous screening of materials of construction mainly from the viewpoint of corrosion resistance in the harsh process conditions of IS process, it was planned to fabricate the IS components and examine their integrity in the process environments. At present, among the components of IS process plant consisting of three chemical reaction sections, i.e., the Bunsen reaction section, the sulfuric acid decomposition section and the hydrogen iodide decomposition section, key components in the Bunsen reaction section was fabricated.

Heat Demand

Heat demand dominates the final energy use in northern cities. This study examines how changes in heat demand may affect solutions for zero-emission energy systems, energy system flexibility with variable renewable electricity production, and the use of existing energy systems for deep decarbonization. Helsinki city (60 °N) in the year 2050 is used as a case for the analysis. The future district heating demand is estimated considering activity-driven factors such as population increase, raising the ambient temperature, and building energy efficiency improvements. The effect of the heat demand on energy system transition is investigated through two scenarios. The BIO-GAS scenario employs emission-free gas technologies, bio-boilers and heat pumps. The WIND scenario is based on large-scale wind power with power-to-heat conversion, heat pumps, and bio-boilers. The BIO-GAS scenario combined with a low heat demand profile (−12% from 2018 level) yields 16% lower yearly costs compared to a business-as-usual higher heat demand. In the WIND-scenario, improving the lower heat demand in 2050 could save the annual system 6–13% in terms of cost, depending on the scale of wind power.

Analysis of wind power utilization efficiency around the world and Europe has revealed the gap between feasible and factual power generation. The paper presents an investigation of wind power generation dynamics, penetration levels into the electricity system, and dependence of capacity factors on the hub height and the rotor diameter of wind turbines in the Baltic States. These factors are the main for the evaluation of wind power utilization efficiency. Wind power penetration levels show that possibilities of the energy system to accept more wind power installations in the Baltic States are far away from its limit. Besides, dependence of high wind turbines capacity factors’ on the hub height and the rotor diameter in the range of 20–120 m was revealed.

Wake Effect

A technical and economic model of a wind power plant has been developed. Parameterization was carried out and the main parameters of the wind power plant were identified. Statistical relationships of parameters with capital investments in wind turbines and costs of their operation and maintenance were established. The criterion for the search for optimal parameters is taken as the minimum discounted unit costs for the production of electrical energy for the economic life of the wind power plant. To do this, the electricity production in a wind power plant must be maximized by reducing the so-called wake effect that is created in a wind farm due to the shading of some wind turbines by others. The velocity reduction behind each wind turbine is estimated. An algorithm for optimizing the parameters of a wind power plant has been developed. An optimization model was used to determine the parameters of the Hasia wind power plant.
