I/ Let’s take a look at Hace :

Today we introduce you to a new company: HACE (Hydro Air Concept Energy). Created in 2013, this company proposes a new solution to produce energy, from waves and coastal protection services. We had the chance to be received by Mr. Jean-Luc STANEK, founder of the project at the Technopole Montesquieu in Martillac, near Bordeaux. On the spot, the company shares its premises and works mainly with engineers and students. Other firms or start-ups such as Interdrones, Oficina Numérica or Kitewinter can also be found there. It is also possible to rent equipment (3D printers, laser cutters…) to bring projects to life, all at prices accessible to all. Currently very few at the head of HACE, the team should grow in the coming months.

HACE creates sustainable energy with waves, whatever their size. Its installations are composed of two large arms and a caisson that adapts to the size of the waves (small, medium or large) in the sea or in fresh water. Thanks to the air pressure generated by the waves, the turbines in the arms start up and create electricity without interruption.

HACE works like a piston engine compressing air:

  1. The waves are the pistons compressing the air in the columns
  2. The compressed air is recovered by the overpressure box
  3. The compressed air drives a revolutionary low pressure turbine producing electricity
  4. The air flow and its pressure determine the power supplied
  • Floating structure on the sea allowing the creation of electricity

II/ Hace’s commitment to sustainability :

Through its activity, HACE contributes to achieve part of the Sustainable Development Goals (SDGs) promoted by the UN. Following our interview with Mr. STANEK, let’s discover together those that particularly resonate for the company in the SDG matrix:

SDG 7 – Clean and Affordable Energy, SDG 9 – Industry, Innovation and Infrastructure, SDG 11 – Sustainable Cities and Communities, SDG 14 – Water Life

Indeed, through its activity itself, HACE is committed to produce clean, ultra-decarbonated (<0.5 gEqCO2/KWh) and affordable (<2 cents/KWh) energy since the energy created comes directly and continuously from the waves. Indeed, small waves are always present at sea, and they are stronger in the evening and in winter, as is the electrical demand. The installation proposed by the company is also financially accessible and offers good value for money: energy absolutely all year round without interruption and regardless of the size of the wave, that is the promise of HACE.

In addition, HACE contributes to the creation of local jobs; fishermen are hired to maintain the machines in the areas where they are installed. The machines are particularly easy to maintain, as the parts are changeable, repairable and the materials are 100% recyclable (as they are made of steel and cast iron for the anchors). The company has adopted the principles of redundancy and predictive maintenance, which means that there is never a malfunction or breakdown.

HACE offers an innovative way to provide low-cost electricity to developing countries. Indeed, after several years of research, Mr. STANEK gathered a panel of specialists (energy engineers for example) to help him rethink the production of energy from marine forces. These machines not only create energy, but also have an important role in preventing the formation of large waves by dephasing them. This has the consequence to protect the coasts and to preserve the biotopes of the ecosystems gathering the fauna and the flora. The energy created can then be distributed in remote areas of the planet and allow isolated families to have access to electricity at lower cost. The company thus combines territorial projects (providing access to electricity) with local communities (maintenance of the installations by local fishermen).

However, a question emerges: what about the impact of HACE on marine biodiversity? Large machines anchored in the seabed could indeed have serious consequences. To address this issue and to continue to improve and optimize what nature gives us, the company has designed its installations to be as close to the surface of the water as possible. In addition, the anchorages of the facilities house nests of larvae of several species in order to increase biodiversity and fishery richness such as phytoplankton that help decarbonize the atmosphere.

How effective might this project also seem for the social and environmental pillars of sustainable development? To answer this question, the SDG matrix is a useful tool we used to qualitatively highlight the SDGs to which HACE contributes. Let’s discover the GOOD PRACTICE SHEET we made, supported by 3 TOOLS!

III/ Hace and the Kedgers?

In addition to raising the awareness of Kedgers (Kedge Business School students) to the Sustainable Development Goals, ODD&THEKEDGERS aims at informing tomorrow’s managers about responsible opportunities in the associative, private and public sectors.

Thus, Mr. STANEK, the founder of HACE, is already collaborating with engineering schools and is ready to collaborate with business schools in order to market and publicize his inventions. The key to doing great projects, as he pointed out during our interview, is to collaborate and educate ourselves on the subjects we care about. This allows us to take a fresh look at the world and move forward with the people we work with.

Moreover, let’s remind you that it is possible as a private individual to come to the Technopole Montesquieu, where HACE is located, to use the different machines at your disposal and allow your projects to be born!
