Highlights
- GreenSpur’s 15MW generator design outperforms industry benchmarks in power density and space envelope.
- Preliminary design is 30% lighter and 70-80% smaller than best-in-class models.
- GreenSpur to work with ORE Catapult to validate the new design through system-level analysis.
Time To ACT plc (AQSE: TTA), an engineering-led group specializing in technology solutions for the energy transition supply chain, has announced a significant development from its GreenSpur business. GreenSpur has created a preliminary 15MW generator design that significantly outperforms industry benchmarks, particularly in terms of power density and space envelope. This breakthrough has the potential to redefine the performance standards for wind energy generators, contributing to more cost-effective solutions in the renewable energy sector.
Groundbreaking Design Achievements
The new generator design, which is still in the early stages of development, was created following requests from a world-leading generator manufacturer and a prominent wind industry original equipment manufacturer (OEM). The preliminary design is already showing remarkable results, being approximately 30% lighter and 70-80% smaller than the current best-in-class generators available in the global market. GreenSpur’s technical team is confident that with further optimisation, they will achieve even greater improvements in these metrics.
One of the key advantages of the GreenSpur design is its multi-stage axial flux design, which not only delivers impressive performance at this scale but is also readily scalable to larger sizes. This scalability opens the door for future innovation and larger wind power systems, ensuring that the design will be relevant and adaptable as the industry evolves. The design also promises meaningful operational and maintenance advantages, aligning with the growing industry demand for cost-effective wind power solutions.
Industry Interest and Next Steps
The innovative 15MW generator design has already attracted considerable interest within the wind energy industry, underscoring its potential to revolutionize the sector. To further validate the design and accelerate its development, GreenSpur has partnered with the Offshore Renewable Energy (ORE) Catapult, a leading research and development organization based in Blyth, UK. Together, they will undertake a comprehensive system-level analysis of the generator integrated into a turbine system.
This collaboration follows GreenSpur's successful development and testing of its prototype machine at the ORE Catapult facility in 2022. The next phase, which is expected to take around 3-4 months, will focus on validating the generator’s performance and commercial readiness. This will be a crucial step toward securing the generator's place in the market and evaluating its commercial potential for both domestic and global markets.
CEO’s Remarks on Progress
Time To ACT’s CEO commented: "This breakthrough 15MW generator design is a testament to GreenSpur’s engineering expertise and its commitment to advancing the technology needed to drive the energy transition. We are excited about the collaboration with ORE Catapult, which will play a key role in validating the generator's performance. As we move forward, we are confident that the new design will meet industry needs for more efficient, scalable, and cost-effective wind power solutions."
Looking ahead, Time To ACT plc and GreenSpur are positioned to play a significant role in the renewable energy transition, with their innovative generator design set to address some of the most pressing challenges facing the wind energy sector. The ongoing validation and development efforts ensure that the company is on track to meet the increasing global demand for sustainable energy solutions.
