Who we are


Provides a liquefied natural gas (LNG) logistics chain between mainland Portugal and Madeira island, including storage and regasification. 

Operates own fleet of 55 cryogenic containers for the transport of LNG and a dedicated LNG Satellite Plant with 600m³ capacity .

We are ready!

Having already been supplied over 2.6 TWh, natural gas currently represents in average, 20% of the electricity production in Madeira island.

The current LNG virtual pipeline between mainland Portugal and Madeira island has achieved international notoriety, as it represents a “small-scale” logistics solution for supplying natural gas to insular regions, as a viable alternative to reception terminals and LNG transport vessels, that usually require lengthy licensing processes, due to its complexity and environmental impact, also associated, to high investments and operating costs, only justified for very high levels of consumption.

In 2017, the Portuguese LNG virtual pipeline was selected by an international jury for the CWC LNG Technological Innovation Award shortlist, a prize awarded on a global scale, along with BP, SHELL and CNOOC Gas & Power Group, worldwide energy operators, the last one being the largest offshore oil and gas producer in China, to which this important recognition was awarded.

With the private investment made in the reinforcement of the LNG containers fleet, and the optimisation of the logistics operation and know-how achieved, GÁSLINK available capabilities allow the supply of natural gas up to 25% of Madeira island’s energy mix, without requiring aditional public or private investment.

This successful concept in Madeira, is replicable in regions where Grupo Sousa operates through its shipowner GS Lines, namely in Azores and Cape Verde.

What can Gáslink do for your business

Ensure the best and most efficient logistics solutions, guaranteeing safety of natural gas supply to small/ medium scale customers, located in insular and outermost regions, such as Azores, Madeira and Cape Verde, where the construction of LNG terminals is not economically viable.

Natural gas consumption has a positive impact on air quality and the health of local populations, contributing to a more sustainable future for the regions.

Benefits of Natural Gas for human health and the environment

It is one of the safest sources of energy and the most environmentally friendly fossil fuel. Emissions of polluting gases, which are harmful to health, are reduced, which helps to reduce air pollution. This not only represents the greatest risk to human health, but is also a factor in the assessment of community sustainability measures (as the reduction of emissions of pollutants with an impact on climate change, such as carbon dioxide, is defined as one of the main goals for global sustainable development).

Policies based on reducing air pollution aim to provide various benefits for human health, from improving air quality, to improving conditions for physical exercise or preventing diseases. As a result, governments, businesses and civil society in general recognize the importance of global action to reduce air pollution, which is reflected in several Sustainable Development Goals (SDOs) under the auspices of the United

Indicative figures


Natural gas is the cleanest fossil fuel. Compared to other fossil fuels such as fuel oil or diesel, in addition to reserves in known deposits consolidating the security of supply needed to meet current global consumption, natural gas emits less carbon dioxide (the main greenhouse agent) and nitrogen oxides (NO and NO2) and ensures the almost total elimination of sulphur oxides (SO2 and SO3) and particles.

The World Health Organization has published on its website, based on scientific evidence, the impact of air pollution, often reporting the harmful effects on human health in situations of long exposure.

Particulate Matter

The World Health Organization identifies a relationship between human exposure to high concentrations of particles and mortality and morbidity. As the existence of particles, even at low concentrations, is harmful to human health, the WHO believes that the level of exposure should be as low as possible.

In 2013, a study by the International Agency for Research on Cancer (IARC) of the World Health Organization concluded that air pollution is carcinogenic to humans and that, in fact, particles are associated in the increase of cancer incidence, especially in the lung.

Natural gas, like the one consumed in Madeira island, allows a 97% reduction in Particulate Matter emissions.

Nitrogen Oxides (NOx)
Epidemiological studies show that bronchitis symptoms in asthmatic children increase with long-term exposure to NOx. In Europe and America, the relationship between the reduction in lung cancer growth and the level of exposure has also been reported.

Natural gas, like the one consumed in Madeira island, makes it possible to reduce NOx emissions by about 95%.

Sulphur dioxide (SOx)
SOx affects the respiratory system and the functioning of the lungs, as well as causing eye irritation. Inflammation of the respiratory system, coughing, worsening of asthma cases and chronic bronchitis. SOx dissolves in water, producing sulphuric acid, which is the main agent of acid rain.

Natural gas, like the one consumed in Madeira island, makes it possible to reduce SOx emissions by about 100%.
