The global demand for copper is set to surge dramatically due to the ongoing energy transition and the expansion of data centers. Projections indicate that by 2050, the amount of copper required will surpass the total mined throughout human history. A significant portion of this copper is utilized in electrical grids, many of which, particularly in the United States, are aging and under increasing strain.
Amir Mashal, founder and CEO of Arcturus, highlights the current challenges: “We’re at a pivotal moment with the rise of AI and the electrification across industries, leading to an overburdened and stressed energy grid.” Traditionally, addressing this issue would involve adding more copper to the grid. However, Mashal’s startup offers an innovative alternative.
Arcturus has developed a method to enhance the efficiency of electrical conductors by infusing carbon nanomaterials into copper and aluminum using laser technology. This advancement allows existing power lines to carry more electricity without increasing their size. Implementing Arcturus’s materials could potentially reduce energy losses in the electrical grid by half. This improvement translates to an immediate increase of approximately 3% in available electricity on average, and up to 10% during peak congestion periods—equivalent to about a year’s worth of demand growth in the U.S.
As copper heats up, its conductivity decreases, leading to more energy being wasted as heat. Mashal notes that this limitation is prevalent across various applications, emphasizing the critical role metals play in modern infrastructure.
While the ultimate goal is to integrate these materials into the electrical grid, Arcturus is initially focusing on smaller-scale applications such as drones, robotics, and data centers. In these sectors, even minor improvements in electrical efficiency can have a significant impact.
Arcturus recently secured $8 million in seed funding, led by Initialized Capital, with contributions from Toyota Ventures, Breakthrough Energy Discovery, 1517, and Wireframe Ventures. This investment will enable the company to scale production from proof-of-concept wire segments measuring a few centimeters to tens of meters. The expanded production will facilitate testing in various applications, including electric motor windings and busbars in power distribution equipment.
Designed as a “drop-in replacement,” Arcturus’s materials can seamlessly integrate into existing copper and aluminum applications without necessitating system redesigns or additional training for handling and installation.
Beyond grid applications, these advanced materials have the potential to make drones lighter and electric vehicles more efficient. By minimizing energy loss to heat, they can also reduce cooling requirements in data centers.
Arcturus’s innovative approach addresses a critical bottleneck in the energy sector. By enhancing the efficiency of existing infrastructure, their technology offers a sustainable solution to meet the growing energy demands of modern industries. As the company progresses from development to deployment, its impact on energy efficiency and sustainability will be closely watched.
