The recent social awareness of the dramatic impact of global warming and the public pressure to do something about it, led consequently to a spectacular demand for seaweed cultivation technology and the willingness to pay. Production of sustainable biomass, CO2 mitigation and, very recently, methane emissions by ruminants are the main reasons for this sudden acceleration. 

This boom in the market demand, the high manpower costs and poor performance in offshore cultivation areas has forced us to rethink seaweed cultivation technology. 

After the FP7 project At~Sea (2012-2015), AtSeaNova NV (AtSea) was founded in 2016. AtSea has invested 2.100.000€ more in order to deliver an integrated industrial seaweed farm concept based on innovative and patented 2D seaweed cultivation substrates comprising a tubular structure, an innovative mooring system and a seeding and harvesting machine. AtSea showed the potential of this disruptive technology at its test farms in Solund Norway and Lastres Spain. Large-scale industrial seaweed cultivation is technically and economically feasible in Europe and abroad. 

Our Mission: Create a paradigm shift in seaweed farming to unlock the potential of seaweeds. 

Our Goal: Market 2D turnkey seaweed farming technology and mechanization thus contributing to the huge challenges related to food, climate change, energy transition, people’s welfare, and much more.
