HACE device rides French waves

Hydro Air Concept Energy (HACE) has conducted the first launch of its 50kW wave energy prototype in the Port of La Rochelle, located in the Biscay Bay, in the western France.

The first observations are very encouraging, according to HACE President Jean Luc Stanek, who also said the device showed ‘perfect buoyancy and stability’.

“The valves responding to the slightest rippling, better than expected with a chop of 20 cm only, positive sensor test,” Stanek informed in a social media update.

HACE has over the past 4 years been developing a wave energy technology that divides the swell to recover energy from all types of waves, with the ability to produce power from small waves of up to 30 cm in height.

Following the launch, the prototype – measuring 20 by 18 meters – was rested on the ground for inspection, final adjustments, checks and various finishing touches.

“The purpose of this ‘scale one’ experiment is to confirm the results of the simulations, scale models, and 1:8 scale prototype, which show that we can produce clean energy that is almost both non-intermittent and in phase with consumption, because the chop and the small waves are always present, while the swell is stronger in the evening, and in winter, at the peak of demand,” Stanek said.

The prototype HACE wave energy device will be relaunched for two months of preliminary tests, subject to weather and securing of funding, Stanek noted.

Offshore Energy Exhibition and Conference (OEEC) 2019

Offshore Energy Exhibition and Conference (OEEC) is where the energy transition takes place. It is Europe’s leading gathering of the entire offshore energy industry and your opportunity to network with highly qualified experts and professionals across global markets.

For more than 12 years OEEC is unique in bringing together the offshore energy industry sectors oil & gas, offshore wind and marine energy. More than 550 exhibitors from around the world present their newest services, projects and innovative products. On top of this OEEC presents international trade missions, pavilions, exclusive network lounges of the OEEC member club, the Startup Zone, matchmaking areas, the Stage and networking drinks. Approximately 12,000 professionals will visit the exhibition, take part in strategic discussions, immersive technical conference sessions focusing on the future and technical developments in the industry. Three days of networking and together shaping the future of energy.

So the question is not if but how you will be participating at Offshore Energy 2019.
