Historical inventory of wind power projects in Vietnam updated 2022-05-04 "post FIT race" This release is complete for projects with COD or PPA at the end of the FIT period. The number of records is 548, of which 360 refer to active projects phases, and 215 have investment costs. Each record describes a wind project phase. The table includes projects at all stages of the lifecycle. Some have been mentioned years ago and are now of historical interest only. Some have just a signed exploration MoU. All records are referenced to one or several public sources. Fields: Record status, Project stage, Project name, Owner, Location (hamlet, commune, province, region, longitude, latitude), Location type (onshore/nearshore/offshore), Capacity (MWp), Connection plan, Turbines, Investment (VND or USD), dates (MoU, Investment Licence,, Groundbreaking), Note and sources. The dataset also include: Descriptive data paper. A CSV export of the table. Python module to read the data from the CSV and python script to print the descriptive statistics. Public sources only. Lacks visibility on the offshore zones proposed by Provinces for inclusion in the PDP8.

The global renewable power support policy dataset was compiled by Sarah Hafner (Anglia Ruskin University, United Kingdom) and Johan Lilliestam (Institute for Advanced Sustainability Studies (IASS), Germany) in February-July 2017 and completed during 2017. The work was led by Johan Lilliestam but each author gathered half of the data. The data was formatted and checked for internal consistency by Tim Tröndle, IASS. All non-commercial users are allowed to use and manipulate our data, but are required to give appropriate attribution. Hence, please cite this data as: Hafner, S. & Lilliestam, J. (2019): The global renewable power support dataset. Institute for Advanced Sustainability Studies (IASS) & Anglia Ruskin University, Potsdam & Cambridge. Doi: https://doi.org/ 10.5281/zenodo.3371375. If you are interested in contributing to and further developing the dataset: please contact Johan Lilliestam (IASS Potsdam). The search was done in publically available sources, including but not limited to the IEA renewables policy database, res-legal.eu, Worldbank data, as well as data from the responsible national ministries. Our data holds information on 10 specific policy instruments explicitly dedicated to the support for expansion of renewable electricity generation 1990-2016; some instruments, including taxation of non-renewables or emission trading, affect other sectors than renewable power, but are mentioned in their original policy description to also be dedicated to increasing renewable power. Our data concerns national policy measures, but ignores policies enacted on higher (e.g. EU-level in Europe) or lower (e.g. state-level policies in Canada, USA) political levels. For example, the “no support” entry for the United Arab Emirates indicates that there were no national-level policies: all policies were, in this case, emirate-specific. The data exists in two versions: one version readable for humans (RE_policies_fullglobal.xlsx) and for each instrument type as .csv. The information in the two versions is identical and differs only in the way it is displayed. Please refer to the metadata file for a detailed description of the dataset and the data categories.

Global climate change governance has changed substantially in the last decade, with a shift in focus from negotiating globally agreed greenhouse gas (GHG) reduction targets to nationally determined contributions, as enshrined in the 2015 Paris Agreement. This paper analyses trends in adoption of national climate legislation and strategies, GHG targets, and renewable and energy efficiency targets in almost all UNFCCC Parties, focusing on the period from 2007 to 2017. The uniqueness and added value of this paper reside in its broad sweep of countries, the more than decade-long coverage and the use of objective metrics rather than normative judgements. Key results show that national climate legislation and strategies witnessed a strong increase in the first half of the assessed decade, likely due to the political lead up to the Copenhagen Climate Conference in 2009, but have somewhat stagnated in recent years, currently covering 69% of global GHG emissions (almost 50% of countries). In comparison, the coverage of GHG targets increased considerably in the run up to adoption of the Paris Agreement and 93% of global GHG emissions are currently covered by such targets. Renewable energy targets saw a steady spread, with 79% of the global GHG emissions covered in 2017 compared to 45% in 2007, with a steep increase in developing countries. Key policy insightsThe number of countries that have national legislation and strategies in place increased strongly up to 2012, but the increase has levelled off in recent years, now covering 69% of global emissions by 2017 (49% of countries and 76% of global population).Economy-wide GHG reduction targets witnessed a strong increase in the build up to 2015 and are adopted by countries covering 93% of global GHG emissions (81% not counting USA) and 91% of global population (86% not counting USA) in 2017.Renewable energy targets saw a steady increase throughout the last decade with coverage of countries in 2017 comparable to that of GHG targets.Key shifts in national measures coincide with landmark international events – an increase in legislation and strategy in the build-up to the Copenhagen Climate Conference and an increase in targets around the Paris Agreement – emphasizing the importance of the international process to maintaining national momentum.

During the refurbishment of a supermarket in northern Italy, the HFC refrigeration plant has been replaced by a new CO2 transcritical system. A deep synergy has been favoured with the HVAC system, by allowing mutual heat exchanges at various temperature levels. Simulations have been performed at the design stage, with a TRNSYS based tool and in-house types for the refrigerating unit and the display cabinets. The plant was fully instrumented, and the availability of measured data on the new system allowed assessing its actual performance and validating the model. It was then possible to investigate the effectiveness of the heat recovery solutions applied, and to optimize their control rules.

As a consequence of the coming into force of the EU F-Gas Regulation 517/2014, enormous technological developments have been experienced on the part of transcritical R744 supermarket refrigeration systems. These have led to the wide acceptance of multi-ejector based technologies as the most promising hydrofluorocarbon (HFC)-free solutions for commercial refrigeration sector. Approximately 50 stores have been equipped with a multi-ejector block. Furthermore, such an expedient is expected to offer significant electricity savings in other energy-demanding applications (e.g. hotels, gyms) as well, even in warm climates. This work summarizes the evolution of R744 multi-ejector enhanced parallel compression system architectures for supermarket applications. Additionally, their technological aspects as well as the potential energy benefits along with some relevant field/experimental measurements are also presented. Furthermore, the experience gained in the use of the multi-ejector concept in transcritical R744 heat pump technologies is summed up. At last, the persistent challenges needing to be faced are revealed.

Salt hydrates are often used as heat storage materials according to their interesting thermal properties (high latent and specific heat). Their main drawback is their large supercooling, where the material may remain liquid below its melting point. However, this property should be turned into a benefit if a reliable way of triggering crystallization is developed, as heat could be released on demand. Sodium Acetate Trihydrate (SAT, CH3COONa.3H2O), which can exhibit 90K of supercooling, was used for this study. For a better understanding of how heat is released after crystallization triggering, caused by seeding, a fully new method was developed to measure the samples’ opacification, using a HeNe laser (633 nm) coupled with a photodetector, measuring the solid fraction thanks to the difference between liquid and solid specular transmittance. This technique was compared with temperature measurement and image processing, showing consistency between the different methods.
