Solar heat in Vietnam, the new workshop of the world

A 5,000 m² flat plate collector field is currently being built at PrimeAsia Leather in Ba Ria-Vung Tau, Vietnam. The turnkey supplier of the installation is Danish-based Arcon-Sunmark, which has its own flat plate collector production facilities in this South East Asian country. According to a press release published at the beginning of last November, the solar plant is scheduled to come online in early 2018. The solar heat is said to be used for preparing the animal skins and evaporating the factory’s waste water.

Construtora AlttiMore than 3,500 solar water heating systems have been in operation at blocks of flats across Brazil’s ‘solar city’ Belo Horizonte. This figure, an estimate by organisations which were previously part of a business cluster called BH Solar, affirms the city’s exceptional status in Brazil and around the world.

How to approach green construction in the tropical zone

While nearly zero energy projects in Europe focus on reducing heat demand, green buildings in tropical Singapore require lower cooling loads. To study and discuss methods to meet cooling needs, construction and energy experts from all around the world met in Singapore in late October for a two-day workshop organised by the Building & Construction Authority Singapore (BCA) and the IEA’s Buildings and Communities Programme (EBC).

Australia: Think Big, Think Solar

In Australia, the deployment of large commercial solar thermal plants is picking up speed. This year, Monash University had a solar field of 0.5 MW put into operation and aims to expand it to 1 MW. The solar heat that is fed into the district heating system of the large campus area in Clayton, a suburb of Melbourne, is said to meet the entire heat demand in summer. Currently, Danish Aalborg CSP is in dialogue with Perth-based Agrimin about the supply of solar process heat to a planned sulphate of potash (SOP) mine and processing factory in the state of Western Australia.

EU Funding for Solutions to Decarbonise Heating and Cooling Market

A search for ‘solar thermal’ in a recently published 195-page document titled Secure, Clean and Efficient Energy will not return encouraging results (see the document at the bottom). The publication by the Horizon 2020 Work Programme 2018-2020 shows only 6 entries in total. “Solar thermal is definitely not a priority of the new programme,” said Daniel Mugnier, Head of R&D at French engineering services company Tecsol. “And even if the European Solar Thermal Technology & Innovation Platform were to try to promote several hot topics, there’s only one call [LC-SC3-RES-7-2019 on solar process heat] dedicated to the technology.”

Italy: Solar District Heating Shows Few Installations but Good Prospects

The map shows the three existing SDH plants in Varese, Sansicario and Lodi (red circles). A fourth with a gross area of about 600 m² is expected to come online in 2020 to feed heat into Turin’s district network operated by the Iren Group utility (yellow cirle). (Source: Ambiente Italia)

Substantial solar resources and a generous incentive scheme called Conto Termico 2.0: Perfect conditions, it seems, for the widespread use of solar district heating. But barriers such as a low gas price and the concentration of district heating in a small part of Italy have so far limited deployment to a few installed systems.

USA: Concentrated Solar Thermal for Biosolid Drying

Since the summer, two parabolic trough collectors have been drying sludge at a waste water treatment plant in Surprise in the state of Arizona, USA. The test project was developed by US-based Heat2Hydro to evaluate the effectiveness of this solution. The objective is to reduce the water content of the sludge and make it easier to transport. The municipality aims at expanding solar drying capacity to 5 MW thermal in about two years.
