Elon Musk: Fusion Will Probably Be More Expensive Than Wind, Solar – Futurism

On Tuesday, a team of MIT researchers made a big splash when they announced that their SPARC compact fusion reactor is very likely to work.

The announcement, detailed in seven papers penned by dozens of scientists from a laundry list of research institutions, claimed that the researchers were on a straight path to achieving fusion power generating power from fusing atomic nuclei together like the Sun, rather than splitting them,like a nuclear power plant. The promise is a never-ending source of clean power without running the risk of a nuclear disaster.

Tesla CEO and billionaire Elon Musk says hes impressed by the research with one major catch: the cost.

Its cool and for sure can and should be done, he tweeted about the fusion research,but I suspect its best case will be more costly than windand solar (aka big fusion reactor in sky).

Fusion energy has been the holy grail for energy generation for over half a century. While the science and technology surrounding reactor designs have come a long way, Musk is right that it remains an elusive dream.

Cost isnt the only issue facing it. As of right now, its simply not viable yet.

Despite all that, the people working on the next generation of fusion reactors are undeterred. The SPARC team at MIT is hoping to get to the point where their reactor puts out ten times the amount of energy it consumes.

But as weve heard many times before, the technology is still well over a decade away their goal is to start generating electricity starting in 2035.

And then, like Musk said, fusion energy could be a costly endeavor. The price of wind and solar energy have plummeted over the years, giving them a more-than-healthy head start over fusion.

Developing a functioning and efficient fusion reactor is also proving to be an extremely costly process. The ITER fusion power plant, soon to be the largest of its kind in the world, is an international collaboration with a sky-high price tag: a whopping $22 billion a conservative estimate,critics say.

The US Department of Energy has long been skeptical of ITERs plans. Congress confirmed it had approved a $115 million investment in 2016, but support for the project dwindled throughout president Donald Trumps first term. Only $50 million were set aside by the Department of Energy this year including for both national and international fusion energy research and development.

Despite the lack of enthusiasm for ITER, US lawmakers havent given up on solar [fusion?]. Earlier this month, the US House of Representatives approved a fusion energy commercialization program to support a burgeoning industry of private fusion startups.

The hopeis to make fusion a reality through public-private partnerships very much in the same vain as NASAs collaboration with SpaceX and other contractors.

By scaling down operations who needs a multi-billion dollar, football field-sized reactor? some startups are hoping to come up with their own solutions in achieving fusion energy.

Fusion is poised for a SpaceX moment,' CEO of startup General Fusion Christofer Mowry told NBC last year.

A 2018 paper explored what the economy of fusion energy could look like in the coming decades. While the costs strongly depend on what the exact designs of the fusion reactors look like, the electricity price could become comparable to that of solar and wind, the papers authors argue.

But it may not be a question of either or fusion is perhaps more likely to be just part of the solution. According to a study commissioned by a British fusion power startup, fusion may be a way to make up for electricity shortfalls in the renewable energy sector.

In other words, wind and solar alone wont be enough to meet demands and keep climate change in check. Fusion could help by replacing current power generation from coal and natural gas.
