Production
Under the umbrella of a new brand known as Hyfinity, VINCI Construction has brought together all the know-how required for design-build projects for carbon-free hydrogen production plants. It delivers turnkey projects to its clients, whether they are energy producers or large industrial companies. VINCI is a partner and shareholder in Genvia, a company created in 2021 at the initiative of the CEA (French Atomic Energy Commission) and Schlumberger, whose objective is the industrialization of a promising high-temperature electrolyte technology. VINCI is also one of the 30 industrial companies that launched the HyDeal Ambition in 2021. The aim is to prepare the European decarbonized hydrogen industry of the future that will take over the exploitation of fossil fuels.
Storage, transportation and distribution
The Group has specialist subsidiaries, such as Geostock, which are able to offer hydrogen storage solutions through carbonization to manufacturers, energy companies and governments. Currently, a quarter of fossil fuel production is stored permanently, mainly for strategic government reserves. Storing hydrogen in tanks or caves is a major challenge for the industry.
Uses
Thanks to its profile as an integrator, combining knowledge of industrial processes and expertise in large-scale fluid and electrical systems, VINCI Energies is ideally placed to support the industrial energy transition. On the roads, the imminent arrival of hydrogen-powered vehicles poses a new challenge: refueling these vehicles in service areas. VINCI Autoroutes is introducing an increasing number of projects for green hydrogen refueling stations. The aeronautical sector is also counting on hydrogen to reduce its carbon footprint. Numerous experiments are underway in airport infrastructures managed by VINCI Airports. At Lyon Saint Exupéry airport, as part of a partnership with Airbus and Air Liquide, teams are working to implement decarbonized hydrogen installations: initially in gaseous form to supply heavy vehicles (at the airport itself and connecting the airport to the city) with 2 tonnes of fuel per day by 2025, and then in liquid form to refuel future aircraft by 2035. In Japan, three hydrogen stations are already operating at the Kansai airports managed by VINCI Airports, including one that powers forklifts used for cargo operations. In Chile, teams are studying the installation of a hydrogen filling station to meet future needs within the airport itself and the region in general.
5) Eco driving – system of the University of Patras:
The aim of the University of Patras is to inform and raise awareness of drivers regarding the environment and not only to reduce accidents due to misuse of the car (use of mobile devices while driving, driver inexperience or loss of concentration and behavior towards the laws), reduced financial capacity for car maintenance at the scheduled time, the existence of minimal cameras on highways to monitor speed as well as reduce accidents), pollutants that due to the age of cars are constantly increasing and have direct negative effects on the respiratory system of citizens. Hydrogen (H) is the most abundant atom in the universe, but it is almost never found in its pure state alone. It is always combined with other chemical elements such as water (H2O), hydrocarbons (CxHy) or living organisms. The extraction of hydrogen from these primary resources requires energy. Currently, most of the world’s hydrogen is produced from fossil fuels, which release carbon into the atmosphere: we are talking about grey hydrogen. Hydrogen is currently used in many industries: refining, metallurgy, glass, electronics, textiles, fertilizers as well as in the aerospace sector – this is nothing new for VINCI! Through Cegelec Space (VINCI Energies), a long-standing partner of the Kourou space base in French Guiana, the Group has more than 50 years of experience in fluid systems related to hydrogen, the fuel used for Ariane rockets. More than 90 million tons of hydrogen are produced annually, more than 95% from high-carbon processes. 1,300 million tons is the global hydrogen production estimated for 2050 by Bloomberg.
Hydrogen: the missing link in the energy transition?
In order to achieve the Paris Agreement climate goals and keep global warming below two degrees Celsius, it is essential to move away from fossil fuels such as oil, coal and natural gas. This means finding alternatives. These include: renewable energy sources – with solar and wind power leading the way. Although they are growing rapidly, their intermittent nature means that they cannot meet all of the world’s energy needs. Hydrogen could help overcome this problem. Alongside already established energies such as nuclear power, it is one of the most promising candidates for completing this “missing link” in the energy transition. Hydrogen has many advantages. Firstly, it has the highest energy-to-mass ratio. In other words: one kilogram of hydrogen releases three times more energy than one kilogram of petrol. In the form of dihydrogen (H), it can be stored and transported like any other gas and can be used as a primary energy source when burned in boilers, engines and turbines – a combustion process that does not emit CO2, but water vapour. It can also be used to power fuel cells to generate electricity or to provide energy storage solutions for wind and photovoltaic farms. It can also help form hydrocarbons by combining with carbon (CO or CO) and then recovering it from the atmosphere or from industrial fumes. These hydrocarbons are then considered “low carbon”, as they use carbon already emitted by other industries. However, large-scale use of hydrogen requires the removal of significant economic, regulatory and technological barriers. The main challenge is to produce it in sufficient quantities and at a reasonable price using processes that do not emit CO2. Many governments have decided to make decarbonized hydrogen one of the cornerstones of their energy transition strategies. This is particularly true in Europe, where leading economies are demonstrating the continent’s desire to be a pioneer in the development of the sector. The strategy published by the European Commission in July 2020 aims to increase the share of hydrogen in the EU’s energy mix from the current 2% to 13-14% by 2050.
