With COP21 just five months away, growing numbers of initiatives are bringing together researchers, start-ups, businesses and municipalities to jointly build solutions faced with the challenge represented by climate change. The Innov’Climat exhibition is one of them. Presented in Paris, the city that will be hosting the international climate conference, it brought together start-ups and businesses from 3 to 8 July with a focus on technological innovations to tackle climate change. Here, we look back on three major innovations and projects.
Organised by the French environment and energy management agency (ADEME), the French ministry of the environment, sustainable development and energy, and the City of Paris, Innov’Climat presented dozens of innovative projects. From waste recycling and recovery to renewable energy development, these are just some of the areas to be worked on to reduce the economy’s global energy footprint and move towards a low-carbon world.
BioGNVAL: harnessing a region’s local resources to produce renewable energy
Coordinated by SUEZ ENVIRONNEMENT, the BioGNVAL project aims to recover biogas from wastewater treatment as a renewable and easily storable energy: liquid biofuel. The biogas obtained from the recovery of sludge is made up of methane and CO2. The methane is first separated from the CO2 with a cryogenic process, then liquefied for use as a fuel in vehicles. The biomethane obtained in this way is a locally-produced renewable energy, making it possible to reduce greenhouse gas emissions linked to transportation and industrial activities.

beyond the sea: inspired by kite surfing to tow boats
Conceived by the sailor Yves Parliers, the beyond the sea project aims to develop a technology for towing boats with kite-based sails, as used up until now primarily for kite surfing. The kites could offer 200 to 800 sq.m of sails.
Kite-based towing could be used in a number of areas depending on the project’s sponsors: merchant navy, pleasure craft or even fishing. This would offer economic and ecological benefits: for instance, with a 320 sq.m kite, the fuel savings on a transatlantic crossing would be around 25%.

CRIBA project: renovating buildings from the outside to reduce energy bills
A number of governments have made thermal renovation a key area for action in the fight against climate change: better insulated buildings mean less energy used.
In this context, the CRIBA project aims to develop external insulation panels that are quick to install, with a view to accelerating the renovation of existing communal properties. To achieve this, a 3D model of the building is created using drones in order to get a digital mock-up of the building. A bespoke timber panel framework is then created and fitted on the building’s external walls. These panels are filled with insulating materials, such as cellulose wadding, to improve their energy performance.
This initiative is being coordinated by Syrthea, the company in charge of the pilot project in France’s Les Landes region .
