    Dataset for European Installed Offshore Wind Turbines (until year end 2017)
    (Cranfield University, 2018-06-11 09:18) Cevasco, Debora; Collu, Maurizio
    Introduction and aimThis dataset is aimed to list and collect the main characteristics of the European Offshore Wind Farms (to end of 2017). Firstly, this work wants to update and extend the one started by Zhang et al. [1, who gathered the main information and identified the drivetrain types for some of offshore EU wind turbines’ installed, until the end of 2011.Secondly, the wind turbines belonging to the population studied by Carroll et al. [2, [3 (in their reliability database), are identified and analysed more in details.Dataset organisationThe dataset is organised in an Excel worksheet, consisting of:sheet 1 - “Legend”Acronyms and colour coded legend are explained. Additionally the following acronyms are used in the Excel work and throughout this introduction:- WT(s) = Wind Turbine(s)- WF(s) = Wind Farm(s)sheet 2 - "EU WFs”Data from Zhang et al. [1 have been verified and updated by accessing the main information of the wind farms (see link in reference in the section). In particular, for each project, the following information are reported: - WF name, capacity and country - number of WTs - WTs manufacturer/type - type of control, gearbox, generator, and converter - year when WF was online - average distance from shore - current status of the WFsheet 3 - "EU WFs (Fully-Grid Connected)”The fully-grid connected, and still in operation, wind farms are selected out of the ones listed in sheet 1. In the main table (Range(“A1:N83”)), the WTs are identified in the four drivetrain types (and type D sub-types), defined by Perez et al. [4 (N2:N83). A table reporting the acronyms for the “if” cycle on the WT characteristics (speed, gearbox and generator) is reported in cells Range(“AH2:AL11”).Based on this latter, cells in Range(“Q1:AD84”) contain “if” cycles for identifying the share of each drivetrain type on the total installed capacity. The results are plotted in a pie chart, gathering type A and B. Finally, the table in Range(“AS1:CA86”) wants to verify how much of the actual installed (fully-grid connected) capacity is accounted in this dataset. WindEurope report on offshore wind energy statistics, to the end of 2017 [5, is used as a reference, and the sharing to the total capacity of the several manufacturers and of the top 5 countries and is checked.sheet 4 - “Strath. Stats (population info)”For a deeper understanding of the population analysed by Carroll et al. [2, the WTs with the following characteristics have been outlined (by the use of “if” cycles on the main table of sheet 2): - at least 3 year old structure (in 2016) - geared WTs with an induction machine (either SGIG, WRIG or DFIG)Among these, structures between 3 and 5 years old and above 5 years old are distinguished as done by the reference.References[1 Z.

    A numerical study of deep borehole heat exchangers in unconventional geothermal systems
    (Cranfield University, 2018-10-22 10:16) Renaud, Théo
    Poster presented at the Cranfield Doctoral Network Annual Event 2018.The geothermal energy sector is facing numerous challenges related to heat recovery efficiency and economic feasibility. Ongoing research on superheated/supercritical geothermal system, potentially representing a intensive amount of energy, is developed in Europe notably the Iceland Deep Drilling project (IDDP). The well IDDP-1, which reached a magma intrusion at a depth of 2100 m, raised new opportunities to untap the geothermal potential near shallow magmatic intrusions. Given their highly corrosive nature, geothermal fluids weaken the wellbore’s integrity during conventional geothermal production. Deep Borehole Heat Exchangers (DBHE) that do not require fluid exchange between the surface and the wells represent a strategic alternative to recovering heat from these unconventional geothermal resources, while minimising the risk of in-situ reservoir damage. The thermal influence and heat recovery associated with a hypothetical DBHE drilled into the IDDP geological settings were investigated via Computational Fluid Dynamics (CFD) techniques until 10 years of production, when the system reaches full equilibrium. Two wellbore designs were simulated, based on simplified geological properties from the IDDP-1 well description. The results show that, during the first year of production, the output temperature is function of the working fluid velocity before reaching pseudo-steady state behaviour. The cooling perturbation near the bottom hole is shown to grow radially from 10 to 40 m between 1 and 10 years of production, and the output thermal power calculated after 10 years reaches 1.2 MW for a single well.

    Developments in CO2 Compression and Purification Unit (CPU) for Oxy-fuel Combustion Power Plant
    (Cranfield University, 2018-10-22 10:25) Yan Yan, Harry
    Poster presented at the Cranfield Doctoral Network Annual Event 2018.Developments in Carbon Dioxide Compression and Purication Unit (CPU) for Oxyfuel Combustion Power Plant. Oxyfuel combustion technology as one of three major carbon capture technologies, which has been largely investigated from bench scale to demonstration scale. The difference of carbon dioxide gas quality in oxyfuel combustion technology which require additional process with high cost and energy penalty than that of pre- and post-combustion capture technology. In this work, previous work from the oxyfuel combustion demonstration projects and industrial technologies of CPU led by Air Products, Air Liquide, Linde and Praxair have been reviewed. A novel concept that using wet ozone direct oxidation absorption for simultaneous removal SOx and NOx for CPU has been proposed and validated in Aspen Plus. The results indicated that 99% NO, 90% NO2 and nearly 100% of SO2 was removed at pH 11 before compression and the purity of product CO2 can achieve 99.7%. Comparison with the previous technologies, this method achieve high purity of product CO2 with simplified process and can realize the negative emission in oxyfuel combustion power plant.
