Imagine if a tidal energy generator could be 3D printed and assembled anywhere in the world using recycled materials. This is the groundbreaking approach of the London-based startup, Spiralis Energy, which not only generates clean electricity but also reduces environmental impact.
The young company is pioneering new pathways toward a greener and more secure energy future, with upcoming trials in the waters off Alderney that could revolutionize how we produce and use energy.
The unique feature of the Spiralis generator: a modular and sustainable innovation
Spiralis Energy’s tidal energy generator utilizes two electricity-generating screws, named “Axial Skelter.” Mounted on a floating platform, these screws are approximately 65 feet long each and are entirely made from 3D-printed plastic.
While this generator is reminiscent of an Archimedean screw used in other energy production systems, it stands out for its cross-sectional aluminum sheets that generate greater torque while creating a low profile on the upper side. Spiralis Energy opted for a modular design to facilitate transport and assembly, allowing the system to be 3D printed anywhere globally by robots and transported as a kit before assembly.
This innovative concept aims to harness tidal currents to generate energy efficiently and sustainably. By utilizing the kinetic energy of tides, a clean and renewable source, the generator helps reduce dependence on fossil fuels and greenhouse gas emissions.
Additionally, it is designed to minimize the impact on the marine ecosystem and is recyclable, as its screws can be melted down and reused, being made from waste plastic. According to Spiralis Energy, this generator has the potential to mark a significant step toward a greener and more sustainable energy future, with the possibility of being replicated in other regions around the world. This technology represents a significant advancement in the renewable energy sector.
As previously mentioned, the London startup plans to conduct trials in the waters off Alderney to assess the generator’s potential in the island’s tidal currents during the winter months. If successful, this initiative could open new economic opportunities for Alderney, attracting investment and creating local jobs.
Moreover, it would provide an additional source of renewable energy for the island. Spiralis Energy intends to establish a local branch and supply clean energy to Alderney’s grid at a low cost. The startup plans to compete for Contracts for Difference (CFD) offered by the UK government. Alderney’s Policy and Finance Committee (PFC) has expressed support for using the island’s waters as a testing ground.
