Nova has worked with global electric vehicle leaders Tesla to add energy storage to its tidal technology, creating the world’s first baseload tidal power plant in 2018.
As well as producing baseload tidal power which can displace traditional baseload forms such as coal and nuclear, Nova's technology can respond instantaneously to meet changes in client demand.
This controllable output gives tidal power and energy storage a unique ability to displace diesel generation in coastal areas around the world.
Tidal energy is the perfect partner for energy storage - predictable, repeating every six hours. Nova’s smart control technology can also be used with a range of power sources (wind, solar, marine, diesel) and across different types of energy storage (electric batteries, flow batteries, thermal, hydrogen).
This graph shows real world data from Nova’s Shetland Tidal Array. The natural ebb and flow of the tide repeats every six hours, creating four predictable periods of generation per day, illustrated in green. The gaps between each generation cycle are due to the slowing of the tide as it turns and changes direction.
On average, ‘slack tide’ lasts 20 to 30 minutes. Energy storage at the Shetland site allows electricity generated from the tide to be stored during peak generation periods. Electricity is then exported to the grid during the slack periods when the tide is changing direction. This provides a source of constant ‘baseload’ delivery of electricity to the grid, shown in orange.
Our technology seamlessly integrates energy storage with renewable energy generators and consumers. As the share of electricity from intermittent renewables (primarily wind and solar) increases, there will be an increasing requirement for the flexible supply provided by energy storage. We can provide expertise in energy storage design, development, installation, monitoring and integration, with different types of energy storage (electric batteries, flow batteries, thermal, hydrogen) and generation technologies (wind, solar, marine, diesel).
