Bondalti is the largest Portuguese company in the chemical industry, now also expanding to complementary areas, such as water treatment, through its subsidiaries Enkrott and Aema.

The company produces in the Iberian Peninsula and operate internationally. Italy, France, the United Kingdom, the Czech Republic and Germany are just a few examples of the destinations of its products. Bondalti ranks first in Aniline sales in Europe, as a non-integrated producer, and is the largest Iberian producer of Chlorine. The company exports more than 90 percent of its total production.

Bondalti is part of the José de Mello Group – an economic group with a stable, nationally based shareholder structure, and one of the largest Portuguese business groups.

With a strong commitment to the climate transition based on innovation and sustainable technology, Bondalti is a reference in the Portuguese hydrogen value chain. The company believes that the chemical industry will be a key player in the production and storage of green energy, recycling and recovery of waste, providing products that promote energy efficiency and the adoption of forms of sustainable mobility, or even the capture, storage and use of carbon dioxide.

In line with these objectives, Bondalti is committed to being an integral part of the solution within a framework of sustainable development, not only for the value it creates through the products it makes available to society, but also for all the projects it is developing within the framework of the climate transition.

The company is a member of the BCSD – Business Council for Sustainable Development and of the Portuguese Association of Chemical Companies, having signed the Responsible Action commitment.

Role in the project

Bondalti will contribute with the overall coordination of GREENH2ATLANTIC, by supporting Project Management and Coordination activities. Bondalti is an experienced industrial operator of electrolysis processes and will co-lead the activities   concerning system operation and performance monitoring at the site, in collaboration with the other project partners. Furthermore, Bondalti will have a key contribution to the project in the following tasks:

  • Electrolyser system design covering all project phases
  • System commissioning, operation and demonstration
  • Development of the innovative Energy Management System (EMS)
  • Validation of the business case
  • Development of financial plan and commercial strategy for different off-takers

Relevant Previous Projects

Bondalti has an extensive expertise in project and design, construction, operation, maintenance and asset management of large-scale industrial units.

Currently, it is the second largest user of hydrogen and ammonia in Portugal, both used for the Aniline production process. This has been achieved by continuously investing in R&D.

Bondalti considers that the most important knowledge gaps filled by previous projects are related to the project and design, construction, operation, maintenance and asset management of large-scale electrolysers. Bondalti’s considerable experience in large scale power modulating electrolysers, in membrane cell technology and in the development and implementation of membranes characterization and performance predictive tool will be of critical importance to accelerate the pilot-to-market of electrolysers.

Based on its extensive experience in chlor-alkali electrolysis processes, Bondalti developed knowledge on membrane cell technology and implemented characterization tools and operating procedures targeting energy costs reduction, which is one the main challenges for the green H2 industry deployment.

In this context, we would highlight the following:

  • Design, construction and operation of a new chloralkaline electrolysis: The new plant was part of a two-year project and a 60M€ investment at the site with an installed capacity of 68,000 tones/year. The new facility produces chlorine, caustic soda and hydrogen through electrolysis, hydrochloric acid and sodium hypochlorite;
  • E-NOx: Valorization of NOx streams through electrochemical processes. The main objective of the E-NOx R&D project is the development of an innovative and disruptive technology that overcomes the limitations of traditional catalytic reactors in the removal of NOx and N2O present in industrial exhaust streams from the nitric acid production process;
  • WinAminão: Development of benzene direct amination into aniline. The project was funded by the Portuguese National Innovation Agency;
  • CUFTECH (CUF Technology): Improve sustainability of water resources as well energy using process intensification. The project was funded by the Portuguese National Innovation Agency;
  • PILLS (Process Intensification methodologies applied to Liquid-Liquid Systems in structured equipment): Develop a new generation of flexible and high-performance process equipment (micro through to meso structured) dealing with two-phase liquid/liquid-reactions. The project was funded by the 7 FP (Theme 4 – NMP - Nanosciences, Nanotechnologies, Materials and new Production Technologies);
  • Electrocloro – Study and Modelling of Chlorine and Caustic Soda production by Brine Electrodialysis: Optimization of Electrolysis plant aiming to reduce energy consumption and maintenance costs. The project was funded by the Portuguese National Innovation Agency.
