Viet Nam Technology catalogue for power generation and storage. Input for power system modelling

The first Viet Nam Technology Catalogue was published in 2019. This new version includes all the technologies from the 2019 version that have been reviewed and updated where necessary. A main focus of the update has been to add new subcategories of technologies (roof-top solar PV, floating offshore wind, low wind speed turbines, improved flexibility of coal fired plants and pollution prevention technologies for coal power) as well as completely new technology descriptions and data sheets (tidal power, wave power, carbon capture and storage, coal CFB boilers and industrial cogeneration).

This publication is developed under the Danish-Vietnamese Energy Partnership.

The technologies described in this catalogue cover both very mature technologies and emerging technologies, which
are expected to improve significantly over the coming decades, both with respect to performance and cost. This
implies that the cost and performance of some technologies may be estimated with a rather high level of certainty
whereas, in the case of other technologies, both cost and performance today and in the future is associated with a
high level of uncertainty. All technologies have been grouped within one of four categories of technological
development described in the section on research and development indicating their technological progress, their
future development perspectives and the uncertainty related to the projection of cost and performance data.

The technologies in the catalogue include the power production unit and the connection to the grid. This means
that the boundary for both cost and performance data are the generation assets plus the infrastructure required to
deliver the energy to the main grid. For electricity, this is the nearest substation of the transmission grid. This
implies that a MW of electricity represents the net electricity delivered, i.e. the gross generation minus the auxiliary
electricity consumed at the plant. Hence, efficiencies are also net efficiencies.

The text and data have been edited based on Vietnamese cases to represent local conditions. For the mid- and long-
term future (2030 and 2050) international references have been relied upon for most technologies since Vietnamese
data is expected to converge to these international values. In the short run differences may exist, especially for the
emerging technologies. Differences in the short run can be caused by e.g. current rules and regulations and level of
market maturity of the technology. Differences in both the short and long run can be caused by local physical
conditions, e.g. seabed material and offshore conditions can affect costs of offshore wind farms and wind speed can
affect the dimensioning of rotor vs. generator which can influence the cost, or domestic coal quality can affect
efficiency and variable cost of coal-fired plants as well.

Land use is assessed but the cost of land is not included in the total cost assessment since this depends on local
conditions.
