Hydropower is energy from water sources such as the ocean, rivers and waterfalls.
“Mini-hydro” means which can apply to sites ranging from a tiny scheme to electrify a single home, to a few hundred kilowatts for selling into the National Grid. Small-scale hydropower is one of the most cost-effective and reliable energy technologies to be considered for providing clean electricity generation.
The key advantages of small hydro includes:
- High efficiency (70 - 90%), by far the best of all energy technologies;
- High capacity factor (typically >50%);
- High level of predictability, varying with annual rainfall patterns;
- Slow rate of change; the output power varies only gradually from day to day (not from minute to minute).
With its long-lasting and robust technology; systems can readily be engineered to last for 50 years or more, being also environmentally friendly, run-of-river installations not having the same kinds of adverse effect on the local environment as large-scale hydro.
NRR-Marilyn 7 kW Tidal and Wave Hydro Turbine specs
- Helix type propeller, made from fibreglass , with large power coefficient, capable to generate 7+ kW at 2.3 m/s water speed along the rivers, creeks and other inland type of running water across the country;
- Pricing starting with $34,950/unit toward $29,875/unit/platform of four;
- Using floating type of configuration, Marilyn is easy deployable, in order to maximize energy generation from potential places along the Europe/US inland running rivers;
- Reduced components imply increased system reliability.
