Foundations

Sperra - Canal Solar

Canal Solar Built by 3D Concrete Printing. Canal solar is a groundbreaking dual-use solar technology that generates clean energy while providing shade to agricultural irrigation canals. Canal solar has the potential to generate tens of gigawatts of renewable energy and save tens of billions of gallons of fresh water annually in the U.S., all while avoiding the need to convert more farmland or public lands to utility-scale ground-mount solar.

Anchors

Sperra - Gravity Anchors for Floating Solar

Sperra has developed a pioneering solution for anchoring floating solar systems with their 3D Concrete Printed Gravity Anchors. These anchors are specifically engineered to meet the unique requirements of solar installations on water bodies, offering significant advantages over traditional anchor methods. Their streamlined design optimizes efficiency and minimizes material usage, resulting in cost savings throughout the project's lifetime. Additionally, these anchors are manufactured using sustainable practices, reducing the carbon footprint compared to conventional anchor production and transportation. Notably, up to 65% of the concrete in these anchors is replaced with more sustainable materials. The design also promotes increased marine biodiversity through the use of bio-supportive materials and geometries, which enhance local marine ecosystems. Sperra provides a turnkey solution that integrates seamlessly into floating solar projects, allowing for efficient installation and operation. This innovation represents a significant advancement in the field of sustainable energy deployment on water bodies.

Sperra - Torpedo Anchors for Offshore Clean Energy

Sperra's Torpedo Anchors are designed to meet the growing demands of offshore clean energy projects, especially in deeper waters where wind energy potential is highest. These anchors utilize advanced 3D printing manufacturing techniques to offer a more efficient and cost-effective solution compared to traditional methods. The anchors significantly decrease the overall cost of floating offshore wind projects by up to 3% through the use of local materials and automation, minimizing the impact of steel price fluctuations. An impressive 96% reduction in carbon emissions associated with anchoring is achieved, appealing to sustainable construction needs. Sperra Torpedo Anchors also promote local economic growth by involving disadvantaged communities in their manufacturing process, creating jobs and fostering a low-carbon industry. With funding support from the US Department of Energy, Sperra is optimizing its technology to make offshore wind energy more competitive and sustainable.

Subsea Energy Storage

Sperra - Subsea Pumped Hydroelectric Energy Storage System

Sperra Subsea Pumped Hydroelectric Energy Storage is an innovative technology designed to enhance renewable energy integration, particularly with offshore wind and solar plants. Addressing the critical need for Long-Duration Energy Storage (LDES), it employs large concrete spheres placed on the ocean floor, using water movement to store and release energy. This subsea system can be utilized independently along coastlines or in conjunction with offshore energy installations, allowing for significant cost savings and new revenue streams. Key features include a patented multi-sphere 'pod' design and local manufacturing through automated 3D concrete printing, reducing costs by streamlining construction processes. With modules ranging from 2 MW to 5 MW, the system is constructed using locally sourced materials, boosting domestic employment. It enhances grid resiliency by creating new offshore storage sites and offers environmental benefits like minimal land disruption and resilience to climate-related challenges. This aligns with the goals identified by multiple national energy authorities to support decarbonization strategies.
