Renewable Energy Sector Faces Potential Shortage of High Voltage Transmission Cables Amidst Global Expansion

The burgeoning green energy revolution is accelerating, with global renewable capacity projected to hit 7,300 GW by 2028. As the demand for renewable energy grows, so does the necessity for efficient transmission systems to transport this power over greater distances. The video highlights the challenges and costs associated with expanding transmission infrastructure, particularly the shortage of high voltage direct current (HVDC) cables, which are essential for long-distance energy transfer. It discusses the potential of projects like XLINKS, which aims to connect Morocco and Devon, UK, over 3,800 km, emphasizing the economic and technical hurdles in scaling up the production and supply of transmission cables outside of China.

• Global renewable capacity is expected to reach 7,300 GW by 2028 due to the increasing deployment of green technologies.
• The distance energy needs to travel is growing, necessitating the development of efficient transmission systems like HVDC cables.
• The XLINKS project exemplifies the push for long-distance energy transfer, proposing to connect Morocco to the UK over 3,800 km and highlighting cost and efficiency considerations.
• High voltage cables, crucial for offshore and cross-border energy projects, face a looming shortage outside of China, where most manufacturing is concentrated.
• Three companies dominate more than 75% of the HVDC cable market, leading to a scarcity of suppliers as demand surges.
• Efforts to expand cable manufacturing capacity in places like the UK are underway, but challenges such as high capital costs, the need for specialized facilities, and trained personnel persist.
• The shortage of HVDC cables could hinder the connection of renewable energy sources to the grid, posing a significant challenge to the green energy revolution.
