Fukushima Daiichi decommissioning delay highlights TEPCO's revised timeline, spent fuel removal at Units 1 and 2, safety enclosures, decontamination, fuel debris extraction by robot arm, and contaminated water management under stricter radiation control.

 

Key Points

A government revised schedule pushing back spent fuel removal and decommissioning milestones at Fukushima Daiichi.

✅ TEPCO delays spent fuel removal at Units 1 and 2 for safety.

✅ Enclosures, decontamination, and robotics mitigate radioactive risk.

✅ Contaminated water cut target: 170 tons/day to 100 by 2025.

 

The Japanese government decided Friday to delay the removal of spent fuel from the Fukushima Daiichi nuclear power plant's Nos. 1 and 2 reactors by as much as five years, casting doubt on whether it can stick to its timeframe for dismantling the crippled complex.

The process of removing the spent fuel from the units' pools had previously been scheduled to begin in the year through March 2024.

In its latest decommissioning plan, the government said the plant's operator, Tokyo Electric Power Company Holdings Inc., will not begin the roughly two-year process (a timeline comparable to major reactor refurbishment programs seen worldwide) at the No. 1 unit at least until the year through March 2028 and may wait until the year through March 2029.

Work at the No. 2 unit is now slated to start between the year through March 2025 and the year through March 2027, it said.

The delay is necessary to take further safety precautions such as the construction of an enclosure around the No. 1 unit to prevent the spread of radioactive dust, and decontamination of the No. 2 unit, even as authorities have begun reopening previously off-limits towns nearby, the government said. It is the fourth time it has revised its schedule for removing the spent fuel rods.

"It's a very difficult process and it's hard to know what to expect. The most important thing is the safety of the workers and the surrounding area," industry minister Hiroshi Kajiyama told a press conference.

The government set a new goal of finishing the removal of the 4,741 spent fuel rods across all six of the plant's reactors by the year through March 2032, amid ongoing debates about the consequences of early nuclear plant closures elsewhere.

Plant operator TEPCO has started the process at the No. 3 unit and already finished at the No. 4 unit, which was off-line for regular maintenance at the time of the disaster. A schedule has yet to be set for the Nos. 5 and 6 reactors.

While the government maintained its overarching timeframe of finishing the decommissioning of the plant 30 to 40 years from the 2011 crisis triggered by a magnitude 9.0 earthquake and tsunami, there may be further delays, even as milestones at other nuclear projects are being reached worldwide.

The government said it will begin removing fuel debris from the three reactors that experienced core meltdowns in the year through March 2022, starting with the No. 2 unit as part of broader reactor decommissioning efforts.

The process, considered the most difficult part of the decommissioning plan, will involve using a robot arm, reflecting progress in advanced reactors technologies, to initially remove small amounts of debris, moving up to larger amounts.

The government also said it will aim to reduce the pace at which contaminated water at the plant increases. Water for cooling the melted cores, mixed with underground water, amounts to around 170 tons a day. That number will be brought down to 100 tons by 2025, it said.

The water is being treated to remove the most radioactive materials and stored in tanks on the plant's grounds, but already more than 1 million tons has been collected and space is expected to run out by the summer of 2022.

This Floating Hotel Will Generate Electricity By Rotating All Day

Floating Rotating Eco Hotel harnesses renewable energy via VAWTAU, recycles rainwater for greywater, and follows zero-waste principles. This mobile, off-grid, Qatar-based resort generates electricity by slow 360-degree rotation while offering luxury amenities.

 

Key Points

A mobile, off-grid hotel that rotates to generate power, uses VAWTAU, recycles greywater, and targets zero-waste.

✅ Rotates 360 deg in 24 hours to produce electricity

✅ VAWTAU system: vertical-axis turbine and sun umbrella

✅ Rain capture and greywater recycling minimize waste

 

A new eco-friendly, floating hotel plans to generate its own electricity by rotating while guests relax on board, echoing developments like the solar Marriott hotel in sustainable hospitality.

Led by Hayri Atak Architectural Design Studio (HAADS), the structure will be completely mobile, meaning it can float from place to place, never sitting in a permanent position. Building began in March 2020 and the architects aim for it to be up and running by 2025.

It will be based in Qatar, but has the potential to be located in different areas due to its mobility, and it sits within a region advancing projects such as solar hydrogen production that signal a broader clean-energy shift.

The design includes minimum energy loss and a zero waste principle at its core, aligning with progress in wave energy research that aims to power a clean future. As it will rotate around all day long, this will generate electrical energy to power the whole hotel.

But guests won’t feel too dizzy, as it takes 24 hours for the hotel to spin 360 degrees.

The floating hotel will stay within areas with continuous currents, to ensure that it is always rotating, drawing on ideas from ocean and river power systems that exploit natural flows. This type of green energy production is called ‘vawtau’ (vertical axis wind turbine and umbrella) which works like a wind turbine on the vertical axis, while alternative approaches like kite-based wind energy target stronger, high-altitude currents as well, and functions as a sun umbrella on the coastal band.

Beyond marine-current concepts such as underwater kites, the structure will also make use of rainwater to create power. A cover on the top of the hotel will collect rain to be used for greywater recycling. This is when wastewater is plumbed straight back into toilets, washing machines or outside taps to maximise efficiency.

The whole surface area is around 35,000 m², comparable in scale to emerging floating solar plants that demonstrate modular, water-based infrastructure, and there are a total of 152 rooms. It will have three different entrances so that there is access to the land at any time of the day, thanks to the 140-degree pier that surrounds it.

There will also be indoor and outdoor swimming pools, a sauna, spa, gym, mini golf course and other activity areas.

Electric vehicles to transform the aftermarket … eventually

Heavy-Duty Truck Electrification is disrupting the aftermarket as diesel declines: fewer parts, regenerative braking, emissions rules, e-drives, gearboxes, and software engineering needs reshape service demand, while ICE fleets persist for years.

 

Key Points

Transition of heavy trucks to EV systems, reducing parts and emissions while reshaping aftermarket service and skills.

✅ 33% fewer parts; regenerative braking slashes brake wear

✅ Diesel share declines; EVs and natural gas slowly gain

✅ Aftermarket shifts to e-drives, gearboxes, software and service

 

Those who sell parts and repair trucks might feel uneasy when reports emerge about a coming generation of electric trucks.

There are reportedly about 33% fewer parts to consider when internal combustion engines and transmissions are replaced by electric motors. Features such as regenerative braking are expected to dramatically reduce brake wear. As for many of the fluids needed to keep components moving? They can remain in their tanks and drums.

Think of them as disruptors. But presenters during the annual Heavy Duty Aftermarket Dialogue are stressing that the changes are not coming overnight. Chris Patterson, a consultant and former Daimler Trucks North America CEO, noted that the Daimler electrification plan underscores the shift as he counts just 50 electrified heavy trucks in North America.

About 88% of today’s trucks run on diesel, with the remaining 12% mostly powered by gasoline, said John Blodgett, MacKay and Company’s vice-president of sales and marketing. Five years out, even amid talk of an EV inflection point, he expects 1% to be electric, 2% to be natural gas, 12% to be gasoline, and 84% on diesel.

But a decade from now, forecasts suggest a split of 76% diesel, 11% gasoline, 7% electric, and 5% natural gas, with a fraction of a percent relying on hydrogen-electric power. Existing internal combustion engines will still be in service, and need to be serviced, but aftermarket suppliers are now preparing for their roles in the mix, especially as Canada’s EV opportunity comes into focus for North American players.

“This is real, for sure,” said Delphi Technologies CEO Rick Dauch.

Aftermarket support is needed
“As programs are launched five to six years from now, what are the parts coming back?” he asked the crowd. “Braking and steering. The fuel injection business will go down, but not for 20-25 years.” The electric vehicles will also require a gear box and motor.

“You still have a business model,” he assured the crowd of aftermarket professionals.

Shifting emissions standards are largely responsible for the transformation that is occurring. In Europe, Volkswagen’s diesel emissions scandal and future emissions rules of Euro 7 will essentially sideline diesel-powered cars, even as electric buses have yet to take over transit systems. Delphi’s light-duty diesel business has dropped 70% in just five years, leading to plant closures in Spain, France and England.

“We’ve got a billion-dollar business in electrification, last year down $200 million because of the downturn in light-duty diesel controllers,” Dauch said. “We think we’re going to double our electrification business in five years.”

That has meant opening five new plants in Eastern European markets like Turkey, Romania and Poland alone.

Deciding when the market will emerge is no small task, however. One new plant in China offered manufacturing capacity in July 2019, but it has yet to make any electric vehicle parts, highlighting mainstream EV challenges tied to policy shifts, because the Chinese government changed the incentive plans for electric vehicles.

‘All in’ on electric vehicles
Dana has also gone “all in” on electrification, said chairman and CEO Jim Kamsickas, referring to Dana’s work on e-drives with Kenworth and Peterbilt. Its gasket business is focusing on the needs of battery cooling systems and enclosures.

But he also puts the demand for new electric vehicle systems in perspective. “The mechanical piece is still going to be there.”

The demand for the new components and systems, however, has both companies challenged to find enough capable software engineers. Delphi has 1,600 of them now, and it needs more.

“Just being a motor supplier, just being an inverter supplier, just being a gearbox supplier itself, yes you’ll get value out of that. But in the longhaul you’re going to need to have engineers,” Kamsickas said of the work to develop systems.

Dauch noted that Delphi will leave the capital-intensive work of producing batteries to other companies in markets like China and Korea. “We’re going to make the systems that are in between – inverters, chargers, battery management systems,” he said.

Difficult change
But people working for European companies that have been built around diesel components are facing difficult days. Dauch refers to one German village with a population of 1,200, about 800 of whom build diesel engine parts. That business is working furiously to shift to producing gasoline parts.

Electrification will face hurdles of its own, of course. Major cities around the world are looking to ban diesel-powered vehicles by 2050, but they still lack the infrastructure needed to charge all the cars and truck fleet charging at scale, he added.

Kamsickas welcomes the disruptive forces.

“This is great,” he said. “It’s making us all think a little differently. It’s just that business models have had to pivot – for you, for us, for everybody.”

They need to be balanced against other business demands, including evolving cross-border EV collaboration dynamics, too.

Said Kamsickas: “Working through the disruption of electrification, it’s how do you financially manage that? Oh, by the way, the last time I checked there are [company] shareholders and stakeholders you need to take care of.”

“It’s going to be tough,” Dauch agreed, referring to the changes for suppliers. “The next three to four years are really going to be game changes. “There’ll be some survivors and some losers, that’s for sure.”

California's solar energy gains go up in wildfire smoke

California Wildfire Smoke Impact on Solar reduces photovoltaic output, as particulate pollution, soot, and haze dim sunlight and foul panels, cutting utility-scale generation and grid reliability across CAISO during peak demand and heatwaves.

 

Key Points

How smoke and soot cut solar irradiance and foul panels, slashing PV generation and straining CAISO grid operations.

✅ Smoke blocks sunlight; soot deposition reduces panel efficiency.

✅ CAISO reported ~30% drop versus July during peak smoke.

✅ Longer fire seasons threaten solar reliability and capacity planning.

 

Smoke from California’s unprecedented wildfires was so bad that it cut a significant chunk of solar power production in the state, even as U.S. solar generation rose in 2022 nationwide. Solar power generation dropped off by nearly a third in early September as wildfires darkened the skies with smoke, according to the US Energy Information Administration.

Those fires create thick smoke, laden with particles that block sunlight both when they’re in the air and when they settle onto solar panels. In the first two weeks of September, soot and smoke caused solar-powered electricity generation to fall 30 percent compared to the July average, according to the California Independent System Operator (CAISO), which oversees nearly all utility-scale solar energy in California, where wind and solar curtailments have been rising amid grid constraints. It was a 13.4 percent decrease from the same period last year, even though solar capacity in the state has grown about 5 percent since September 2019.

California depends on solar installations for nearly 20 percent of its electricity generation, and has more solar capacity than the next five US states trailing it combined as it works to manage its solar boom sustainably. It will need even more renewable power to meet its goal of 100 percent clean electricity generation by 2045, building on a recent near-100% renewable milestone that underscored the transition. The state’s emphasis on solar power is part of its long-term efforts to avoid more devastating effects of climate change. But in the short term, California’s renewables are already grappling with rising temperatures.

Two records were smashed early this September that contributed to the loss of solar power. California surpassed 2 million acres burned in a single fire season for the first time (1.7 million more acres have burned since then). And on September 15th, small particle pollution reached the highest levels recorded since 2000, according to the California Air Resources Board. Winds that stoked the flames also drove pollution from the largest fires in Northern California to Southern California, where there are more solar farms.

Smaller residential and commercial solar systems were affected, too, and solar panels during grid blackouts typically shut off for safety, although smoke was the primary issue here. “A lot of my systems were producing zero power,” Steve Pariani, founder of the solar installation company Solar Pro Energy Systems, told the San Mateo Daily Journal in September.

As the planet heats up, California’s fire seasons have grown longer, and blazes are tearing through more land than ever before, while grid operators are also seeing rising curtailments as they integrate more renewables. For both utilities and smaller solar efforts, wildfire smoke will continue to darken solar energy’s otherwise bright future, even as it becomes the No. 3 renewable source in the U.S. by generation.

Hitachi freezes British nuclear project, books $2.8bn hit

Hitachi UK Nuclear Project Freeze reflects Horizon Nuclear Power's suspended Anglesey plant amid Brexit uncertainty, investor funding gaps, rising safety regulation costs, and a 300 billion yen write-down, impacting Britain's low-carbon electricity plans.

 

Key Points

Hitachi halted Horizon's Anglesey nuclear plant over funding and Brexit risks, recording a 300 billion yen write-down.

✅ 3 trillion yen UK nuclear project funding stalled

✅ 300 billion yen impairment wipes Horizon asset value

✅ Brexit, safety rules raised costs and investor risk

 

Japan’s Hitachi Ltd said on Thursday it has decided to freeze a 3 trillion yen ($28 billion) British nuclear power project and will consequently book a write down of 300 billion yen.

The suspension comes as Hitachi’s Horizon Nuclear Power failed to find private investors for its plans to build a plant in Anglesey, Wales, where local economic concerns have been raised, which promised to provide about 6 percent of Britain’s electricity.

“We’ve made the decision to freeze the project from the economic standpoint as a private company,” Hitachi said in a statement.

Hitachi had called on the British government to boost financial support for the project to appease investor anxiety, but turmoil over the country’s impending exit from the European Union limited the government’s capacity to compile plans, people close to the matter previously said.

Hitachi had called on the British government to boost financial support for the project to appease investor anxiety, but turmoil over the country’s impending exit from the European Union and setbacks at Hinkley Point C limited the government’s capacity to compile plans, people close to the matter previously said.

Hitachi had banked on a group of Japanese investors and the British government each taking a one-third stake in the equity portion of the project, the people said. The project would be financed one-third by equity and rest by debt.

The nuclear writedown wipes off the Horizon unit’s asset value, which stood at 296 billion yen as of September-end.

Hitachi stopped short of scrapping the northern Wales project. The company will continue to discuss with the British government on nuclear power, it said.

However, industry sources said hurdles to proceed with the project are high considering tighter safety regulations since a meltdown at Japan’s Fukushima nuclear power plant in 2011 drove up costs, even as Europe’s nuclear decline strains energy planning.

Analysts and investors viewed the suspension as an effective withdrawal and saw the decision as a positive step that has removed uncertainties for the Japanese conglomerate.

Hitachi bought Horizon in 2012 for 696 million pounds ($1.12 billion), fromE.ON and RWE as the German utilities decided to sell their joint venture following Germany’s nuclear exit after the Fukushima accident.

Hitachi’s latest decision further dims Japan’s export prospects, even as some peers pursue UK offshore wind investments to diversify.

Toshiba Corp last year scrapped its British NuGen project after its US reactor unit Westinghouse went bankrupt, while Westinghouse in China reported no major impact, and it failed to sell NuGen to South Korea’s KEPCO.

Mitsubishi Heavy Industries Ltd has effectively abandoned its Sinop nuclear project in Turkey, a person involved in the project previously told Reuters, as cost estimates had nearly doubled to around 5 trillion yen.

Energy crisis: EU outlines possible gas price cap strategies

EU Gas Price Cap Strategies aim to curb inflation during an energy crisis by capping wholesale gas and electricity generation costs, balancing supply and demand, mitigating subsidies, and safeguarding supply security amid Russia-Ukraine shocks.

 

Key Points

Temporary EU measures to cap gas and power prices, curb inflation, manage demand, and protect supply security.

✅ Flexible temporary price limits to secure gas supplies

✅ Framework cap on gas for electricity generation with demand checks

✅ Risk: subsidies, higher demand, and market distortions

 

The European Commission has outlined possible strategies to cap gas prices as the bloc faces a looming energy crisis this winter. 

Member states are divided over the emergency measures designed to pull down soaring inflation amid Russia's war in Ukraine. 

One proposal is a temporary "flexible" limit on gas prices to ensure that Europe can continue to secure enough gas, EU energy commissioner Kadri Simson said on Tuesday. 

Another option could be an EU-wide "framework" for a price cap on gas used to generate electricity, which would be combined with measures to ensure gas demand does not rise as a result, she said.

EU leaders are meeting on Friday to debate gas price cap strategies amid warnings that Europe's energy nightmare could worsen this winter.

Last week, France, Italy, Poland and 12 other EU countries urged the Commission to propose a broader price cap targeting all wholesale gas trade. 

But Germany -- Europe's biggest gas buyer -- and the Netherlands are among those opposing electricity market reforms within the bloc.

Russia has slashed gas deliveries to Europe since its February invasion of Ukraine, with Moscow blaming the cuts on Western sanctions imposed in response to the invasion, as the EU advances a plan to dump Russian energy across the bloc.

Since then, the EU has agreed on emergency laws to fill gas storage and windfall profit levies to raise money to help consumers with bills. 

Price cap critics
One energy analyst told Euronews that an energy price cap was an "unchartered territory" for the European Union. 

The EU's energy sector is largely liberalised and operates under the fundamental rules of supply and demand, making rolling back electricity prices complex in practice.

"My impression is that member states are looking at prices and quantities in isolation and that's difficult because of economics," said Elisabetta Cornago, a senior energy researcher at the Centre for European Reform.

"It's hard to picture such a level of market intervention This is uncharted territory."

The energy price cap would "quickly start costing billions" because it would force governments to continually subsidise the difference between the real market price and the artificially capped price, another expert said. 

"If you are successful and prices are low and you still get gas, consumers will increase their demand: low price means high demand. Especially now that winter is coming," said Bram Claeys, a senior advisor at the Regulatory Assistance Project.

Nearly $1 Trillion in Investments Estimated by 2030 as Power Sector Transitions to a More Decarbonized and Flexible System

Distributed Energy Resources (DER) are surging as solar PV, battery storage, and demand response decarbonize power, cut costs, and boost grid resilience for utilities, ESCOs, and C&I customers through 2030.

 

Key Points

DER are small-scale, grid-connected assets like solar PV, storage, and demand response that deliver flexible power.

✅ Investments in DER to rise 75% by 2030; $846B in assets, $285B in storage.

✅ Residential solar PV: 49.3% of spend; C&I solar PV: 38.9% by 2030.

✅ Drivers: favorable policy, falling costs, high demand charges, decarbonization.

 

Frost & Sullivan's recent analysis, Growth Opportunities in Distributed Energy, Forecast to 2030, finds that the rate of annual investment in distributed energy resources (DER) will increase by 75% by 2030, with the market set for a decade of high growth. Favorable regulations, declining project and technology costs, and high electricity and demand charges are key factors driving investments in DER across the globe, with rising European demand boosting US solar equipment makers prospects in export markets. The COVID-19 pandemic will reduce investment levels in the short term, but the market will recover. Throughout the decade, $846 billion will be invested in DER, supported by a further $285 billion that will be invested in battery storage, with record solar and storage growth anticipated as installations and investments accelerate.

"The DER business model will play an increasingly pivotal role in the global power mix, as highlighted by BNEF's 2050 outlook and as part of a wider effort to decarbonize the sector," said Maria Benintende, Senior Energy Analyst at Frost & Sullivan. "Additionally, solar photovoltaic (PV) will dominate throughout the decade. Residential solar PV will account for 49.3% of total investment ($419 billion), though policy moves like a potential Solar ITC extension could pressure the US wind market, with commercial and industrial solar PV accounting for a further 38.9% ($330 billion)."

Benintende added: "In developing economies, DER offers a chance to bridge the electricity supply gap that still exists in a number of country markets. Further, in developed markets, DER is a key part of the transition to a cleaner and more resilient energy system, consistent with IRENA's renewables decarbonization findings across the energy sector."

DER offers significant revenue growth prospects for all key market participants, including:

  • Technology original equipment manufacturers (OEMs): Offer flexible after-sales support, including digital solutions such as asset integrity and optimization services for their installed base.
  • System integrators and installers: Target household customers and provide efficient and trustworthy solutions with flexible financial models.
  • Energy service companies (ESCOs): ESCOs should focus on adding DER deployments, in line with US decarbonization pathways and policy goals, to expand and enhance their traditional role of providing energy savings and demand-side management services to customers.

Utility companies: Deployment of DER can create new revenue streams for utility companies, from real-time and flexibility markets, and rapid solar PV growth in China illustrates how momentum in renewables can shape utility strategies.
Growth Opportunities in Distributed Energy, Forecast to 2030 is the latest addition to Frost & Sullivan's Energy and Environment research and analyses available through the Frost & Sullivan Leadership Council, which helps organizations identify a continuous flow of growth opportunities to succeed in an unpredictable future.
