Global Desalination Market Continues to Grow, IDA and GWI Report

According to new data released by the International Desalination Association (IDA) and Global Water Intelligence, the global desalination market continues to grow, marking the fourth year of continued growth following a slowdown in the mid-2000s.

Highlights of the 30th Worldwide Desalting Inventory, published by GWI DesalData in association with the IDA follow. Please note that data is reported as of June 30 of each year. Desalination Capacity Cumulative global contracted capacity, including plants that have been contracted or are under construction, reached 99.8 million cubic meters per day (m3/d) in 2017, up from 95.6 million cubic meters per day in 2016.

This represents an increase in cumulative global contracted capacity of 14 percent, or 282,000 m3/d, from mid-2016 to mid-2017. This growth was seen in both the utility sector―primarily due to new awards in the Gulf, and the industrial sector, where stabilization of oil and gas prices has led to new upstream and downstream projects. The cumulative global installed (online) capacity is now 92.5 million m3/d. This compares with 88.6 million m3/d in 2016.

The total number of desalination plants worldwide across all categories stands at 19,372 (2017) versus 18,983 (2016). Major Feedwater Types Desalination of seawater and brackish water are the two major types of desalination projects. Seawater desalination experienced its largest increase since 2014, driven largely by growth in the utility market in the Gulf, which is likely to retain the largest share of contracted seawater capacity for the foreseeable future.

However, significant awards for seawater desalination plants were also made in China, Singapore and Morocco during the past year. Desalination of brackish water is also growing, with an increase of 29% in contracted capacity for the first half of 2017. The typical brackish water desalination plant is for smaller utilities and industrial users. China accounted for a large portion of growth in these plants, especially during the second half of 2016.

Geographic Trends Large-scale projects around the Red Sea and Gulf account for much of the current recovery in the desalination market. However, the nature of these projects (most are large-scale) means that this region experiences highly variable swings in contracted capacity. A steadier source of contracts can be found in the Asia-Pacific region, where industrial projects dominate the reference list. At the half-way point in 2017, these two regions were almost equal in contracted capacity.

Utility versus Industrial Users Both utility and industrial projects saw double-digit increase in capacity for the full year of 2016, driven by awards for industrial users in the latter part of the year. For the first half of 2017, new utility capacity is down while industrial capacity has increased, due to the volume and size of utility awards in the Gulf during the first half of 2016 and the presence of several extra-large references for refining and petrochemical customers in the first half of 2017.

A closer look at the industrial sector reveals many interesting developments in the upstream oil and gas industry including several projects that may point to the future shape of the market in the offshore oil industry. Technology Type Membrane technologies continue to dominate the desalination market.

For example, in 2017 membrane technology accounted for 2.2 million m3/d of annual contracted capacity while thermal processes accounted for just 0.1 million m3/d during the same period.
