PROJECT DEVELOPMENT

Global Adaptability
Verdant Power's Free Flow System (FFS) is a simple and readily scalable technology that generates reliable, predictable clean energy in a variety of water settings and power delivery arrangements, including the following:

  • Tidal and River Currents

  • Village- to Utility-Scale Grid Power

  • Distributed Generation (Off-Grid Power)

  • Hybrid Power Systems (Microgrid baseload power)

  • Integrated Energy and Clean Water Systems

The simplicity and adaptability of the FFS are key advantages over competing systems, which are most often large, complex technologies intended solely for installation in deep offshore sites located far from where power is needed.

Tidal & River Currents
The Free Flow System is installed in fast-moving (> 1.8 m/s) tides and rivers to convert the kinetic energy of the water currents into electric or mechanical power.   Similar to present-day wind turbines, the blades of FFS turbines are rotated passively by the natural water current at a slow and steady rate. The system does not require any impoundment of the water (dam) and operates fully submerged, invisible from shore. Finally, unlike variable renewable energy resources such as wind and solar, tidal and river currents can be accurately predicted many years in the future, providing a steady and reliable source of clean energy for a variety of usages.

Village- to Utility-Scale Grid Power

A unique aspect of the Free Flow System is its scalable and modular nature, allowing for grid-connected projects ranging from village- to utility-scale. Generally,

an FFS project will have a layout of multiple turbines in an array, arranged to optimize the available resource at a specific site. Systems can be deployed in units ranging from 100 kW - 600 kW for village power ranging up to 5 MW, and with larger units of 350 kW to 1.5 MW for utility-scale projects ranging up to 500 MW.

Off-Grid Opportunities

Beyond traditional grid applications, the Free Flow System creates opportunities for alternative energy project scenarios, including the following:

 

DISTRIBUTED GENERATION

Based on the scalability inherent in its design, the Free Flow System is perfectly suited to nearshore siting and distributed generation applications, meaning power generation at the point of consumption. Generating power on-site, rather than at an offshore location far from end users, eliminates the cost, complexity, and inefficiencies associated with transmission and distribution This setup can be transferred both to urban centers (as exemplified by the RITE Project) as well as rural or village settings located along tidal bodies or rivers.

HYBRID POWER SYSTEMS

The Free Flow System can be integrated into hybrid power systems with other renewable energy technologies (offshore/onshore wind, solar, CHP) for base load power delivery, energy storage, or for use in microgrids. In addition to augmenting power capacity, the FFS can also enhance the reliability and resilience of such hybrid systems, as tidal and river currents are regular and predictable years into the future, and a rugged design and underwater placement make the system less vulnerable to extreme weather events.


 

UNDERWATER/ONSHORE INFRASTRUCTURE

Verdant Power is working to develop methods to integrate the Free Flow System with infrastructure situated onshore near water bodies with high energy potential, or directly underwater, including the following:

• Underwater Data Centers (energy and cooling)

• Underwater/Onshore Electric Vehicle Charging

• Water Purification Systems

• Irrigation and Aeration Pumping
