Scottish cleantech company Nova Innovation has unveiled a the ‘holy grail’ in tidal power that may one day see it replace nuclear and coal-produced energy. Through a deal with Tesla’s battery technology, Nova has achieved a ‘world first’ breakthrough that means it can now deliver predictable power and storage. Nuclear and coal energy have long been promoted because of their ability to deliver baseload generation – steady, constant power. Nova Innovation’s game-changing technology means that, as it is scaled up to hundreds of megawatts in the coming years, baseload tidal power has the ability to displace nuclear and coal generation. Since the start of October, the grid has been supplied by Nova’s Tidal Energy Storage System (TESS) demonstrator, which integrates Nova Innovation’s Shetland Tidal Array with Tesla ’s battery technology to provide clean power ‘on demand’. Simon Forrest, CEO at Nova Innovation, said: “By storing the clean energy generated by the natural ebb and flow of the tide, we can control the supply of electricity to the grid to match demand. This creates a consistent source of completely predictable power from a clean, sustainable resource. “Nova’s expertise in smart grid control, renewable generation and energy storage has delivered this game-changing innovation. We now look forward to expanding our services to other markets and renewable projects.”

Simec Atlantis Energy will beef up the MeyGen tidal array in the Pentland Firth with at least two more of its 2 megawatt turbines. The turbines use more powerful generators and larger rotor diameters, will use a new subsea connection hub and share a single export cable. This will significantly reduce project infrastructure costs by removing the requirement for a dedicated export cable per turbine and should also result in reduced vessel installation costs. The use of larger rotor diameters is in-step with a key cost reduction trend seen in the offshore wind industry.
