ISQ in hydrogen since 2004

ISQ commenced its activities in the hydrogen sector in 2004, by participating in the pioneering and emblematic European project Naturalhy that researched the effects of introducing mixtures of hydrogen with natural gas for transportation in the European natural gas network.

The Naturalhy project specifically focused on the components of material assessment, inspection methodologies, risk assessment and the suitability of existing facilities for the introduction of mixtures of natural gas with hydrogen.

ISQ offers a comprehensive range of Green Hydrogen solutions, encompassing the different stages of the value chain – production, distribution and use – and focusing on maximising safety, reliability and sustainability.

The areas that it has focused on include, but are not limited to, safety, risk assessments, licensing, quality assurance, infrastructure integrity assessment, reliability analysis, modelling and optimisation of the integration of energy systems, and life cycle assessments, as well as on several support activities such as metrological assessment, equipment validation and certification and technical training.

Photovoltaic Solar Energy

Portugal is at the forefront of European countries with the greatest potential for growth in the solar energy market and ISQ has become an important partner for entities operating in the sector. Customer support – from small decentralised producers to producers/developers of major photovoltaic plants – is ensured throughout all stages of the value chain.

ISQ’s Energy Services support customers throughout all stages of the value chain with:

  • preliminary technical and economic feasibility studies;
  • analysis of technical specifications;
  • selection of equipment and material, acceptance testing (at the factory and on site);
  • project management, works oversight and monitoring;
  • commissioning;
  • monitoring and performance assurance;
  • operation & maintenance

In the decentralised production sector, ISQ provides a consultancy service specialising in drawing up tender specifications and the subsequent qualitative analysis of bids.

This accumulated experience allows us to provide this range of services in other regions of the world.


A combined cycle power station monitored by ISQ since its construction

Turbogás, a 990 MW combined cycle power station (three 330 MW generators), runs on natural gas and commenced operations in 1999. It has enhanced efficiency, as it takes advantage of the heat of the turbine gases to produce steam, which in turn drives another turbine. Both drive the same generator, allowing a performance of over 50% to be achieved.

Built very close to the Tapada do Outeiro Thermoelectric Power Station, a coal-fired power station that was decommissioned in 2004, its design was based on the economic viability of the gas pipeline, and it was expected that it would consume, at full power, over 50% of the transported natural gas.

ISQ participated in its construction with services from CND and QA/QC, among others, and has maintained a permanent relationship with the project as it supervises the maintenance shutdowns.


ISQ has been playing a major role in the wind energy manufacturing and installation sector. It acts as a leading entity in quality control of the production of different components that make up a wind turbine (metal towers, foundations, nacelles, generators and blades) and, in this context, it has dedicated teams for quality control inspections and NDT in the factory.

ISQ inspects wind energy components in factories in conjunction with EDP Renováveis, to ensure that components released from the factories meet the quality requirements set out in the customer’s tender specifications. Inspections performed in the factory reduce operationl costs associated with lack of quality control and failures that can damage the integrity of the wind turbine.

As an entity with major laboratory holdings, ISQ supports the best wind energy manufacturing companies in the world, by performing tests on wind farm components (vibration, temperature and humidity, HIPOT tests) and customised tests.

In addition to these services, ISQ has played a significant role in the development of new technologies such as the Windfloat demonstrator (demofloat, offshore floating wind energy generation), in which it played an important role in the R&D activities associated with the project. Following this project, ISQ was involved in quality control for the construction of Windfloat Atlantic

​​PHASEWIND: “Blue investment” to drive sustainable technologies

ISQ has developed an integrated system for inspection and non-destructive control of wind tower welds during manufacturing – Phasewind.
This breakthrough development by ISQ, in addition to increasing productivity in the inspection of wind turbine towers during manufacturing, guarantees a higher inspection quality, helping to eliminate human error during the inspection decision and defect detection.

An innovative inspection and monitoring solution that combines different non-destructive and visual testing techniques to perform high-speed, automatic inspections of wind turbine tower welds. This fully automatic inspection system does not require human intervention during its operation because it can digitize and analyze the weld bead through a high resolution camera and advanced ultrasonic techniques that analyze 100% of the weld volume automatically, thus detecting defects, without the need for the presence of operators.


WINDFLOAT: The first floating offshore wind farm in Portugal

ISQ participates in the Windfloat project, the first floating offshore wind farm in Portugal, installed in Viana do Castelo. The services provided by ISQ consist of control by non-destructive tests, dimensional control, watertightness and equipment tests. Based on this new technology, which allows wind exploration in a maritime environment to great depths, replacing the traditional fixed tower on the seabed, clean energy is obtained.

The project is part of the Industrial Strategy for Oceanic Renewable Energies, whose main objective is to create an industrial ‘cluster’ exporting these clean energy technologies with the potential to generate 254 million euros in investment, 280 million euros in gross added value, 119 million euros in the trade balance and 1,500 new jobs.

Windfloat Atlantic, which uses wind energy, is coordinated by EDP through EDP Renováveis ​​and includes technological partner Principle Power, Repsol, venture capital Portugal Ventures and metallurgy A. Silva Matos.

Alto Tâmega Electricity Generation System

ISQ has had a presence in this project since 2017, performing a range of activities. It currently ensures all of the welding quality control for the pressure pipeline connecting the Gouvães and Daivões reservoirs. This is a large diameter pipe made of thick steel, most of which runs underground inside the mountain.

As there is no access to the external surface, all controls during the assembly phase are carried out from inside the pipe. For this purpose, ISQ’s Advanced Testing Engineering team developed an automatic inspection system based on ultrasound technology, which combines several techniques and allows the welds to be examined. It is therefore possible to guarantee compliance with a high likelihood of detection and high discontinuity dimensioning precision. All of the data acquired during the survey is recorded digitally simultaneously.

This system also allows the real-time assessment and permanent recording of the data obtained by ultrasound, making it an important resource for assessment and comparison purposes during future in-service quality controls.
