Siemens Digital Industries Software today announced that Nemo’s Garden, a startup focused on sustainable underwater cultivation of crops, has deployed Siemens’ Xcelerator portfolio of software and services to shorten its innovation cycles and move more rapidly towards industrialization and scale.

Nemo’s Garden was founded in 2021 by Sergio Gamberini, President of Italian scuba diving equipment manufacturer, Ocean Reef Group, and his son, Luca Gamberini. Their team of engineers, divers and scientists have been working to prove the viability of cultivating herbs, fruit and vegetables underwater. Nemo’s Garden’s key innovation, a sub-aqua biosphere, is a unique type of underwater greenhouse, able to harness the positive environmental factors of the ocean – temperature stability, evaporative water generation, CO2 absorption, the abundance of oxygen and inherent protection from pests – to create an environment ideal for crop cultivation.
The team has not only successfully harvested a variety of crops from its prototype biospheres, but also discovered that plants grown in this environment are nutritionally richer than those grown traditionally. The next big hurdle in achieving their goal was to turn this prototype into a solution that could be deployed globally; however, they didn’t want to wait another 10 years to make that happen.
Harsh winters, short summers and initial seafloor-use permit limitations capped Nemo’s Garden to one growth cycle a year, which has meant only one innovation cycle per annum. Design changes, lengthy physical testing and heavy manual monitoring processes during the growth cycle led the Nemo’s Garden team to seek out ways to speed up their innovation and scale the operation. The team reached out to TekSea’s Matteo Cavalleroni for insight on how to leverage cutting edge technologies to achieve their goals. After the initial consultation, Siemens was invited to join the project, leveraging the Xcelerator portfolio of software and it’s services to help Nemo’s Garden get to the next stage of development and get ready for industrialization/commoditization.
“When I first saw Siemens’ digital twin technology, I was mesmerized. Nemo’s Garden is a one-of-a-kind system and we need to adapt to each environment where it is to be installed. If you can model that environment virtually before you start, you can foresee the challenges and address them in the best way,” said Luca Gamberini, Co-Founder, Nemo’s Garden. “We have seen benefits in understanding the flow of water around the shapes of our biospheres. We have a greater understanding of the points of stress on the structure around the biospheres. We also understand how the different interactions of the solar radiation, the temperature and all the physical factors, act on the plants. All thanks to the ability of the digital twin to replicate our system.”
A comprehensive digital twin of the Nemo’s Garden biosphere has been built that encompasses not only its design evolution using Siemens’ NX™ software, but also enables simulation of the growing conditions within it, the impact of the equipment on the body of water, as well as the full environment in which they are installed – all accomplished using Siemens’ Simcenter™ STAR-CCM+™ software. The Nemo’s Garden team are no longer limited by weather conditions, seasonality and short growing seasons or limitations on diving and monitoring. Adaptations to the biospheres can be tested in the virtual world, enabling the team to refine the design at a massively accelerated rate.
