Its seed innovation capacity has considerable potential to make available — on a competitive, sustainable basis — bioresources that do not compete with food crops. Total has taken an interest in the startup with a view to expanding its R&D activities and facilitating its expansion in the biofuel and bioproduct segment.   Total Energy Ventures will sit on the company’s Board of Directors as an observer.   The acquisition of an interest in NexSteppe marks Total Energy Ventures’ eighteenth investment since its creation in 2008.   About Total Energy Ventures   Total Energy Ventures is the corporate venture arm of French energy company Total.
