Hydrogen symbiosis

Fabriek medewerker

Hydrogen is released in the DOW's various naphtha crackers. This hydrogen is now used as a reactant in the DOW Terneuzen production processes, the surplus is used as fuel in the production processes. The companies Yara and ICL-IP can use this hydrogen as a raw material in their production processes.


Win-win for all parties involved

Transport of hydrogen per underground pipeline provides a win-win for all concerned. In the first stage, 4.5 kton H2 per year could be high-quality coupled to Yara. ICL-IP currently consumes hydrogen for the production of hydrogen bromide. The expectation is that the demand for H2 will increase in the coming years. Hydrogen is currently delivered by truck. ICL-IP can benefit from the hydrogen link between Dow and Yara. The pipeline to be used is close to Yara and ICL-IP.

Green Deal

To help realize the project a so-called Green Deal was signed for this business case on March 14, 2016. In the Green Deal permission was asked to use the existing GTS gas transport pipeline, which runs under the channel by Terneuzen from DOW along ICL-IP and Yara. This existing pipeline offers a perfect re-destination for this large-scale industrial symbiosis case in the Gent-Terneuzen Canal Zone. The physical coupling between Dow Benelux and Yara, a distance of approximately 10 km with a tap to ICL-IP (about 400 m), leads to a high-quality H2 distribution and a significant CO₂ reduction.

Iconic project of international allure

The hydrogen link between Dow, Yara and ICL-IP serves as an excellent example to improve the competitive edge in the process industry, which also contributes to ecological and social synergies. The hydrogen link is an inspirational example for future business cases inside and outside the Delta region: a potential iconic project of (inter)national allure!

Intended results

  • Exchange of 4,500 ton of hydrogen per year;
  • CO₂ savings of 10,000 ton per year;
  • Dropped energy consumption by 0.15 PJ per year, comparable to average gas consumption of 3,000 households;
  • Annual reduction of 320 trucks on the roads of Zeeland;
  • Potential for further up-scaling with existing and new companies


Business case

This business case is the result of a unique collaboration between energy & feedstock intensive companies in the Delta region: West North Brabant, Zeeland and the Flemish part of the Gent-Terneuzen Canal Zone. Together they form the Smart Delta Resources (SDR) platform.
Companies nor consumers produce 'waste'. The residual substance of the one is after all valuable raw material for the other. Only so can we produce sustainably, take steps towards the circular economy and gain or retain a competitive advantage in countries or regions that have relatively low-cost raw materials.
The affiliated companies develop business cases through the SDR platform for the exchange of energy and material flows. The professional literature refers to the industrial symbiosis. This type of cooperation aims at three goals:

  1. The exchange of waste that serves as a raw material from another company creates economically attractive business cases that strengthen the international competitiveness of the companies concerned.
  2. SDR contributes to the sustainable growth of industry and to achieving climate goals. This should include, among other things, the reduction of greenhouse gas emissions such as CO₂ and the reduction of fossil fuels.
  3. The close cooperation also offers opportunities for (yet) affiliated companies in the region and / or for companies that are looking for a location, it is attractive to settle in our cross-border Delta region.
