Halo Energy (Somerville, MA) has developed a high-efficiency 3.7m diameter shrouded wind turbine design and is scheduled to deliver its first ten units in the next quarter. The fiberglass and galvanized steel design is derived from jet engine technology, using two closely-coupled, convex shrouds that encircle the turbine blades. The turbine then acts as a passive pump, pulling air over the blades.
This gives the HALO-6.0 turbine a rated capacity of 6 kW and is among the most efficient micro wind solutions in production. It is designed to address the energy requirements of the expanding off-grid telecom tower market worldwide as it can generate twice as much energy as any similar-sized conventional, open-bladed wind turbine.
It can also be mounted directly on telecommunications towers without the need for cranes or additional leased lands, and the tower loading is similar to that of a 1.5m microwave antenna. The turbine has only two moving parts and so increases turbine reliability, serviceability and lifespan, while the blade pitch (angle) is fixed and the turbine passively aligns itself into the prevailing wind without the need for complex subsystems, similarly maintaining the reliability.
"The HALO-6.0 can generate twice as much energy as any similar-sized conventional, open-bladed wind turbine, while reducing diesel-fuel consumption and providing reliable, low-cost renewable electricity," said Halo Energy co-founder and CEO Vincent Loccisano.
Turbine performance has been validated using data collected in 2018 from Halo Energy's test wind turbine in Massachusetts. "From an efficiency perspective, our innovative shroud design outperforms anything we've seen on the market. The size, weight, and price make this an ideal solution for the telecom industry, particularly given the ease of installation and ability to mount directly onto existing cell towers," said Loccisano.
The first commercial unit will be delivered to an Alaskan telecommunications company to eliminate the dependency on diesel generators for remote cell towers. Halo Energy is in discussions with hybrid energy providers in Australia, Canada, Africa, India, and Southeast Asia who bundle solar energy, wind energy and battery storage for
