Subsea Energy Storage System

Advanced Undersea Systems and Technology

Norway is constructing the world’s deepest and longest subsea road tunnel, a $2 billion megaproject designed to dramatically improve coastal transportation. The tunnel will stretch for miles beneath the seabed, reaching depths of nearly 1,300 feet below sea level. Once completed, it will allow vehicles to travel safely beneath the ocean, reducing ferry dependence and improving year-round connectivity. Key Facts: • Cost estimated at $2 billion • Reaches about 1,300 feet below sea level • Designed
