In 2019, solar heat capacity additions reached record-breaking levels in industrial sectors around the world, coming to 251 MW in total. The countries at the top of the list were Oman (180 MW), China (53 MW), Mexico (3 MW), India (2 MW) and Germany (1 MW). Ranked by the number of new SHIP systems, China and Mexico were leading the field, at 26 systems each, followed by Germany with 11 new installations. These findings are the result of surveying the about 80 industrial solar heat suppliers listed on the SHIP Supplier World Map, which was created during the international Solar Payback project. The map will be updated in the coming weeks to include the projects put up in 2019. The photo shows one of the new systems, a SHIP plant installed at a chemical factory in Belgium. Its 1,100 m2 field of parabolic trough collectors is being operated by Belgian-based Azteq, which also financed the system and uses it to supply solar steam to a factory in Antwerp. Two other news reports on the SHIP survey results can be found here: news 1 and news 2.
The technology solutions providers participating in the survey reported that overall, 86 systems came online in 2019. This was a bit below the number put up in 2018 (99 systems) and in 2017 (107 systems). The slowdown was mainly the result of a drop in new installations in Mexico (see table 2). The two previous surveys had the Mexican solar industry at the top of the SHIP rankings. But last year, it managed to install only 26 systems compared to 51 in 2018 and 36 in 2017. One reason for the lower interest in renewables throughout the industrial sector, according to Mexican suppliers, was the new government’s support for oil and gas. Other reasons were the delays in decision-making and contract awards by larger industrial clients.

Table 1: Trends in the global SHIP market between 2017 and 2019. The large fluctuations in added capacity were the result of how the Miraah project is being implemented in Oman, as solar steam capacity was added during multiple stages, i.e., 120 MW in 2017 and 180 MW in 2019. The figures for 2018 had to be updated because five projects in India had been postponed to 2019 or later. Source: Solar Payback SHIP Supplier Surveys 2017, 2018 and 2019
By contrast, Chinese turnkey system suppliers completed a decent number of projects in industry in 2019, as the total went up from 15 in 2018 to 26 last year. The Chinese SHIP market is most probably much larger than the survey suggests. Even though local engineering firms use collectors from large manufacturers for industrial systems, some of these systems are not included in the figures supplied by the sales departments of larger Chinese companies participating in the SHIP Supplier World Map survey.

Chinese-based Linuo Paradigma alone listed 18 large systems totalling 48 MW, with an average size of 3,841 m2
. Glasspoint aside, this has been the highest annual capacity addition across all SHIP supplier surveys. US-based Glasspoint specialises in building extra-large solar steam-producing fields for the oil and gas industry. Its first project is the Miraah
system in Oman. According to CCO Seti Gabriel, Glasspoint brought 180 MW of parabolic trough collectors online in Oman in 2019 and Miraah had 360 MW fully in operation by April 2020.
In contrast to 2019’s five top SHIP markets, which were China, Mexico, Germany, India and Spain (see table 2), only one or two industrial solar heat systems were commissioned in Belgium, France, the Netherlands, Turkey and the USA. In addition, Cyprus, Malaysia, Portugal, Saudi Arabia, and Senegal reported their first SHIP installation as part of a Solar Payback survey.

An improved methodology was developed for this year’s global SHIP survey, the fourth survey since 2016. For example, the month of commissioning, i.e., the month in which the system was brought online, was added to the template where technology suppliers fill in information about newly added SHIP plants. This new approach helped remove from the total count those projects that had not yet been commissioned but were still under development.
In addition, aggregated figures showing only the total number of commissioned SHIP plants and the cumulated collector area were not accepted. All technology suppliers provided lists of projects that included at least the system’s location and application, the collector type and the commissioning date. Listing the industrial client for which a specific system was installed was not mandatory, as many of the customers asked not to be named.
The 2020 survey also used the new SHIP definition developed and approved by the IEA Solar Heating and Cooling programme in November 2019 to standardise SHIP data across applications (see the PDF attached to this news article). In the agricultural and service sectors especially, the definition helps to draw a much clearer distinction between industrial and other uses. It also specifies a minimum size of 50 m2 of collector area before a system can be considered in the world statistics, as smaller projects are often set up for demonstration purposes and they are difficult to track.

As in previous years, vacuum tube collectors were the most popular collector technology for SHIP systems, making up as much as 70 % of the total SHIP collector area in 2019. The most popular sort of solar concentrating technology was again parabolic trough collectors, used in 12 projects in 2019 aside from Miraah in Oman. However, sales in that market sector fell slightly from 11,096 m2 in 2018 to 7,542 m2 in 2019. Solar dishes were put up by only two companies, Megawatt Solutions and Quadsun, both based in India. Likewise, linear Fresnel remained a niche technology installed by Belgian-based Rioglass and Spanish-based Solatom during four projects in 2019. Air collectors, which are used mainly in the agricultural sector, were added to the survey for the first time and were the main collector technology for SHIP projects supported by the German´s SHIP subsidy programme.
