The Challenge of Achieving Commercial Fusion Power
Fusion power has long been hailed as a potentially limitless and clean source of energy. However, despite decades of research, commercial fusion power remains elusive. Two main approaches are being explored to achieve this goal: creating a small star on Earth using powerful magnetic fields or using intense lasers to create even smaller stars. Moritz von der Linden, the co-founder and CEO of Marvel Fusion, is confident that his company’s approach will be the one to succeed.
The Inertial Confinement Fusion Approach
Marvel Fusion is pursuing inertial confinement fusion (ICF), which involves using high-powered lasers to compress and heat a small pellet of fuel to incredibly high temperatures, mimicking the conditions found at the core of the sun. This approach has already been demonstrated at the National Ignition Facility (NIF), a Department of Energy lab that achieved controlled fusion reactions in 2022.
Improving Laser Technology
While NIF’s lasers are based on decades-old designs, Marvel is using cutting-edge technology to improve their power and efficiency. The company will soon build a demonstration facility in collaboration with Colorado State University, where two 100-Joule lasers will be used to test its core technology. Shovels hit the dirt on October 16, and von der Linden expects the facility to be operational by early 2027.
The Marvel Fusion Process
The process of achieving fusion at Marvel involves firing lasers in the femtosecond range (one-billionth of a second) at a nanostructured target, blasting away its electrons and scattering the remaining positively charged ions. These ions then hit Marvel’s fuel, igniting a fusion reaction. Currently, Marvel Fusion is using a mix of mainly hydrogen and boron, but von der Linden notes that this can be adjusted as needed.
The Importance of Scaling Up
While the demonstration facility will be an important milestone for Marvel, it is just the first step in achieving commercial fusion power. The company’s ultimate goal is to build a full-scale prototype that can generate useful amounts of power. This requires scaling up the technology while maintaining its efficiency and cost-effectiveness.
The Challenges Ahead
Achieving commercial fusion power will require overcoming numerous technical challenges, including scaling up the laser technology, improving fuel efficiency, and developing materials that can withstand the incredibly high temperatures involved. Additionally, the cost of building a full-scale prototype will be significant, and Marvel will need to secure substantial funding to make it happen.
The Road Ahead
The road to achieving commercial fusion power is long and challenging, but von der Linden is confident that Marvel’s approach has a good chance of success. With its cutting-edge laser technology and innovative fuel mix, the company is poised to take a significant step forward in the quest for fusion power.
