While there is a great deal of excitement about fusion, there are huge challenges too.

The U.K. government has chosen the location for a prototype fusion energy plant, with the country’s Energy Secretary, Jacob Rees-Mogg, describing the technology as “a great hope.”
In a statement Monday, authorities said the STEP facility would be based at the West Burton power station, in Nottinghamshire, England. The aim is to build STEP, which stands for Spherical Tokamak for Energy Production, by 2040.
The government said it would provide £220 million (around $249.6 million) of funding for the STEP project’s first phase, in which the U.K. Atomic Energy Authority will ready a concept design by 2024.
Fusion is not the same as fission, which is used in today’s nuclear power plants. The U.S. Department of Energy describes fusion as occurring “when two atoms slam together to form a heavier atom, like when two hydrogen atoms fuse to form one helium atom.”
The DOE adds that this “is the same process that powers the sun and creates huge amounts of energy—several times greater than fission. It also doesn’t produce highly radioactive fission products.”

In a speech at the Conservative Party Conference in Birmingham, Rees-Mogg, who is the U.K.’s secretary of state for business, energy and industrial strategy, sought to highlight the potential of fusion.
“Fusion is a great hope, it is a potential ace up our sleeve,” he said. “It offers unparalleled potential for clean power production, promising a future of inexhaustible energy that could unshackle us from hydrocarbons and make us truly self-sufficient and secure,” he went on to add.
While there is a great deal of excitement about fusion, there are huge challenges too. The DOE says fusion reactions are “difficult to sustain for long periods of time” due to what it says are “the tremendous amount of pressure and temperature needed to join the nuclei together.”
In his speech, Rees-Mogg made a similar point when he acknowledged that the technological hurdles were “big.” Nevertheless, he was bullish about the U.K.’s prospects going forward.
“We will build the U.K.’s first prototype fusion energy plant in Nottinghamshire, replacing the West Burton coal-fired power station with a beacon of bountiful green energy,” he said.
“The plant will be the first of its kind, built by 2040 and capable of putting energy on the grid. And in doing so, it will prove the commercial viability of fusion energy to the world.”
West Burton A is a coal-fired power station that started generation in 1966. Generation at the facility is slated to end in March 2023.

Monday’s announcement was welcomed by the nuclear industry. Tom Greatrex, who is chief executive of the Nuclear Industry Association, said the news represented “a huge moment for fusion energy in the UK.”
“As we look to moving away from fossil fuels towards net zero, it is important that we find new ways of meeting our growing energy demands,” he later added.
“Fusion offers the opportunity to produce virtually limitless energy that will power low-carbon economies across the world. The UK can play a central role in making that a reality.”
The past few years have seen a number of significant developments in the fusion energy sector.
This surpassed a previous record from 1997, when 22 megajoules of heat energy was generated. The results were achieved at the Joint European Torus, or JET, facility in Oxfordshire, U.K.
Co-funded by the European Commission, Eurofusion is made up of thousands of engineers, scientists, students and other experts from throughout Europe.
The amount of energy produced by the experiment was not huge, however, with reports at the time stating that 59 megajoules could boil around 60 kettles of water.
Leading electric vehicle analyst, author, and industry thought leaders Loren McDonald and Bill Ferro stop by Quick Charge to discuss EV Adoption’s acquisition by Paren, the “crisis” of EV charging reliability, and the real state of the EV market.
Depending on who you listen, EVs are either driving brands to record growth and are about cross that critical 10% of the overall market nationwide, or the future is bleak, the market is down, and EVs just aren’t selling. What’s really going on? Loren and Bill (probably) have some answers.

Chevy EV owners in Texas who have Reliant as their electric utility can now charge for free at night with renewable energy.
Over 150 Chevrolet dealerships across Texas are now offering the Reliant Free Charge Nights plan to new EV buyers. With Free Charge Nights, customers can offset their charging costs by receiving credits for electricity used between 11 pm and 6 am. The plan is powered entirely by renewable energy, thanks to the purchase of renewable energy certificates (RECs).
Rasesh Patel, president of NRG Consumer, says the plan is about making power personal: “We’re excited to help Chevrolet EV drivers offset the cost of charging their vehicle all while having access to a renewable electricity plan.”
This collaboration aims to make EV adoption more appealing by making charging cheaper and greener. GM Energy’s chief revenue officer, Aseem Kapur, emphasized that partnerships like this help build the ecosystem needed to support an all-electric future: “The Reliant Free Charge Nights plan is a great example of how an automaker and an energy company can work together to make EV adoption an easy decision.”
Existing Reliant customers can also sign up for the Free Charge Nights plan. To get started, Chevrolet EV owners need to designate their vehicle on the GM Energy Smart Charging Portal before enrolling in the plan.
Reliant Energy, a subsidiary of NRG Energy, serves over 1.5 million customers in Texas, making it one of the largest electricity providers in the state.

Texas is about to get a major power boost – a new AI-powered virtual power plant (VPP) delivering capacity equivalent to 200,000 homes during peak demand.
NRG Energy is teaming up with Renew Home to bring nearly 1 gigawatt (GW) of capacity to the Texas grid by 2035, aiming to make it more resilient while helping residents save on energy costs.
The new VPP will rely on hundreds of thousands of smart thermostats and other connected home devices, making use of AI technology provided by Google Cloud. These devices, like Vivint and Nest smart thermostats, will be offered to eligible customers at no cost. By automating HVAC adjustments, they help shift energy use to when electricity is cheaper, cleaner, and less strained.
NRG and Renew Home have big plans for the VPP. Starting in spring 2025, the companies plan to roll out the program across Texas, installing these smart thermostats in homes served by NRG’s retail electricity providers. Eventually, they plan to add home battery storage and EVs to expand the power plant’s capabilities.
Texas has faced record-breaking energy demands, with peak usage hitting 85 GW in 2023. As the state’s population grows and extreme weather becomes more frequent, VPPs like this one could play a key role in stabilizing the grid. VPPs aggregate a lot of small-scale energy resources, from smart thermostats to home batteries, and use them to help balance supply and demand during times of high stress on the grid.
This nearly 1 GW VPP will be one of the largest of its kind in Texas. NRG’s president of consumer operations, Rasesh Patel, calls it a “pivotal step” for improving customer experience while making Texas’ energy infrastructure more sustainable and resilient.
In addition to Renew Home, NRG is working with Google Cloud to maximize the power plant’s effectiveness. Google Cloud’s AI and analytics tools will help predict weather conditions, forecast renewable generation, and optimize energy usage, all of which will help make energy management smoother for both customers and the grid.
Ben Brown, CEO of Renew Home, said:
NRG’s commitment to creating a more resilient and sustainable energy future while also making electricity bills more affordable makes them an ideal partner for co-developing this unique VPP program.
This initiative raises the bar for future-proofing our electricity infrastructure and delivering cost savings to customers.
