Axis Sky Renewables develops vertical-axis wind turbines without towers using a design that reduces steel usage and capital expenditures.
The turbine’s innovative blades function as a keel to offer stability through counter-turning momentum as wind energy induces rotation.
Positioned atop a tension leg platform (TLP) above the water surface, the static nacelle houses the generator, with the entire structure securely anchored to the seabed by multiple mooring lines. This design reduces mass for cost-effective and simpler installation and allows tighter spacing to increase power density per area.
The design further enables omni-directional operation while eliminating turbine orientation and simplifies maintenance due to the generator platform’s proximity to the ground.
2. A2P Resources
- Founding Year: 2023
- Location: New Delhi, India
- Use For: Infrastructure Development
A2P Resources delivers advanced renewable energy solutions, including high-efficiency solar photovoltaic modules, inverters, and street lighting systems.
Its solar PV modules, such as the AXIbiperfect and AXIpremium HC, utilize N-Type TOPCon and P-Type Mono passivated emitter and rear contact (PERC) technologies, respectively, to capture energy even in low-light conditions.
Additionally, the startup’s on-grid and hybrid solar inverters feature inbuilt maximum power point tracking (MPPT) to optimize energy yield. Moreover, its solar streetlights offer sustainable illumination for outdoor spaces.
3. SIM Energy
- Founding Year: 2023
- Location: Scotland, UK
- Use For: Continuous Local Renewable Energy Generation
SIM Energy introduces the SIM GEN I, a compact renewable energy device that produces continuous green electricity using atmospheric pressure as its fuel source.
The generator employs a patent-protected configuration combining buoyancy, gravity, and pressure to pump water, which turns a turbine. With a small footprint of 1.5 cubic meters, the SIM GEN I eliminates domestic energy bills and carbon emissions.
In addition, the generator’s output remains unaffected by weather or light conditions and eliminates the need for energy storage solutions.
Moreover, the generator integrates with existing electric heating, lighting, and power systems, thereby offering equal access to renewable energy regardless of location.
4. Salinex
- Founding Year: 2023
- Location: Singapore
- Use For: Wave and Solar Power for Sustainable Shipping
Salinex develops renewable energy technologies, including the solar reel system, tidal turbine, mass momentum generator (MMG), and axial energy exchanger.
The solar reel system features a patent-pending design that deploys panels directly into offshore waters without additional protection and conditions for high-voltage direct current for grid connectivity.
The tidal turbine utilizes a novel cross-flow design with a low-profile blade width that allows operation in shallow waters. The mass momentum generator is a wave energy converter that utilizes ocean wave energy to generate electricity.
Moreover, the axial energy exchanger efficiently recovers energy from the reverse osmosis concentrate stream to pressurize treated brackish or seawater.
5. Weco
- Founding Year:2023
- Location: Hague, Netherlands
- Use For: Wave Energy Converter
Weco offers the Kaizen wave energy converter (WEC), which is a system that uses the kinetic energy of ocean waves’ horizontal motion to generate electricity.
The WEC comprises a frame with an attached screen to capture wave energy, floaters for buoyancy, and an anchoring system for stabilization.
As waves propel the device, one pair of belts unrolls while the other rolls up, creating torque that drives an attached generator, thereby converting mechanical energy into electrical power.
The control system further anticipates incoming waves and adjusts speed and positions accordingly while utilizing sensors that provide real-time data for precise control.
