New nuclear power for New York

July 9, 2025 By EarthWise Leave a Comment

New nuclear power plant is coming in New York

Nuclear power has been around since the 1950s, but it has fallen out of favor in recent decades, in part due to a couple of traumatic disasters at nuclear power plants.  In fact, only two new nuclear power plants have been built in the US in the past 30 years, and they took a very long time and an enormous amount of money to build.

However, in recent times there has been a great deal of developmental work on nuclear power.  Such newer technologies as small modular reactors, molten salt reactors, light water reactors, and more hold promise for safer, less expensive, and higher performance nuclear power.

In late June, New York Governor Kathy Hochul announced that she has instructed the New York Power Authority to develop and construct a zero-emission advanced nuclear power plant in Upstate New York.  The plant is to produce 1 GW of power, about half of what the decommissioned Indian Point Power Plant produced when it provided significant amounts of power to New York City residents.

Renewed interest in nuclear power has emerged in part because of the soaring electricity demand from AI data centers.  Companies like Amazon, Google, and Microsoft have all begun investing in nuclear power for this reason.

NYPA is instructed to begin evaluating technologies, business models, and locations for the new power plant and will seek to secure key partnerships needed for the project.  As things stand, it is not known what technology the plant will use, where in Upstate New York it will be located, how much it will cost to build, who will pay for it, and how long it will take to build.

The race for fusion power

December 9, 2024 By EarthWise Leave a Comment

The race for fusion power is heating up

The sun is powered by fusion energy.  Hydrogen atoms fuse together into helium atoms, liberating vast amounts of energy in the process.  Our understanding of this process emerged early in the 20th century and by the 1950s, research efforts were underway trying to replicate the process on Earth.  If it could be done, fusion would be a source of almost unlimited clean energy.  But there has been a cynical saying going around for half a century:  fusion power is the energy source of the future, and it always will be.

However, in recent years, there has been progress in developing fusion power.  Extraordinarily expensive and colossal machines have produced fusion energy albeit consuming more energy than they make.  However, for a brief moment in 2022, a fusion reactor at Lawrence Livermore National Laboratory did produce more energy than it took to run the machine.

Despite the less than encouraging history, there are now multiple start-up companies dedicated to developing fusion energy and they are optimistic that there will be significant progress over the next few years.

One such company, Commonwealth Fusion Systems, located 40 miles northwest of Boston, is building a fusion reactor called SPARC, that they claim will be producing net energy in 2027.  They say that their next machine, called ARC, will generate electricity for paying customers in the early 2030s.

A handful of other companies, including Type One Energy, Thea Energy, Realta Fusion, Zap Energy, General Fusion, and Helion Energy are also pursuing fusion reactor designs and also expect to have machines running over the next 5 to 10 years.
