REDUCING
Wind Energy power is essential to fighting climate change, yet building the turbines is energy-intensive: It could take between 3 to 11 months to generate the amount of energy that was needed for their construction.
Through HWS’ innovative ideas, wind farm construction could become eco-friendlier, reducing CO2 emissions by 30 to 65%.
Achieves greater heights, increasing generated energy per tower
Local Content: reduces logistics
Material volume reduction
Less Maintenance & Double lifespan
65 % less CO2 EMISSIONS during tower construction
Traditional Steel Tower
1,400 t CO2
Traditional Hybrid Tower
850 t CO2

*Study performed for construction of 5.x MW HH165 m wind turbine tower.
Seventh of the transportation required
Civil work reduction: -75% of crane pads & narrow access roads
80% less material (steel) required during crane manufacturing
Electric powered
35% less CO2 EMISSIONS during Installation of Wind Turbines
AirCRANE enables to build bigger turbines at greater heights, pushing forward onshore wind turbine installation technology and helping to decarbonize our planet.
Performed carbon footprint study shows that over 95% of CO2 emissions in construction of wind foundations come from the required materials (concrete & steel). Hence, achieved percentage of material saving reduction will be directly related and similar to the obtained C02 emissions cut.
