Entergy to spin off nuclear plants into independent company

Methane Hydrate CO2 Sequestration uses carbon capture and nitrogen injection to swap gases in seafloor hydrates along the Gulf of Mexico, releasing methane for electricity while storing CO2, according to new simulation research.

Key Points

A method injecting CO2 and nitrogen into hydrates to store CO2 while releasing methane for power.

✅ Nitrogen aids CO2-methane swap in hydrate cages, speeding sequestration

✅ Gulf Coast proximity to emitters lowers transport and power costs

✅ Revenue from methane electricity could offset carbon capture

The world is quickly realizing it may need to actively pull carbon dioxide out of the atmosphere to stave off the ill effects of climate change. Scientists and engineers have proposed various carbon capture techniques, but most would be extremely expensive—without generating any revenue. No one wants to foot the bill.

One method explored in the past decade might now be a step closer to becoming practical, as a result of a new computer simulation study. The process would involve pumping airborne CO2 down into methane hydrates—large deposits of icy water and methane right under the seafloor, beneath water 500 to 1,000 feet deep—where the gas would be permanently stored, or sequestered. The incoming CO2 would push out the methane, which would be piped to the surface and burned to generate electricity, whether sold locally or via exporters like Hydro-Que9bec to help defray costs, to power the sequestration operation or to bring in revenue to pay for it.

Many methane hydrate deposits exist along the Gulf of Mexico shore and other coastlines. Large power plants and industrial facilities that emit CO2 also line the Gulf Coast, where EPA power plant rules could shape deployment, so one option would be to capture the gas directly from nearby smokestacks, keeping it out of the atmosphere to begin with. And the plants and industries themselves could provide a ready market for the electricity generated.

A methane hydrate is a deposit of frozen, latticelike water molecules. The loose network has many empty, molecular-size pores, or “cages,” that can trap methane molecules rising through cracks in the rock below. The computer simulation shows that pushing out the methane with CO2 is greatly enhanced if a high concentration of nitrogen is also injected, and that the gas swap is a two-step process. (Nitrogen is readily available anywhere, because it makes up 78 percent of the earth’s atmosphere.) In one step the nitrogen enters the cages; this destabilizes the trapped methane, which escapes the cages. In a separate step, the nitrogen helps CO2 crystallize in the emptied cages. The disturbed system “tries to reach a new equilibrium; the balance goes to more CO2 and less methane,” says Kris Darnell, who led the study, published June 27 in the journal Water Resources Research. Darnell recently joined the petroleum engineering software company Novi Labs as a data scientist, after receiving his Ph.D. in geoscience from the University of Texas, where the study was done.

A group of labs, universities and companies had tested the technique in a limited feasibility trial in 2012 on Alaska’s North Slope, where methane hydrates form in sandstone under deep permafrost. They sent CO2 and nitrogen down a pipe into the hydrate. Some CO2 ended up being stored, and some methane was released up the same pipe. That is as far as the experiment was intended to go. “It’s good that Kris [Darnell] could make headway” from that experience, says Ray Boswell at the U.S. Department of Energy’s National Energy Technology Laboratory, who was one of the Alaska experiment leaders but was not involved in the new study. The new simulation also showed that the swap of CO2 for methane is likely to be much more extensive—and to happen quicker—if CO2 enters at one end of a hydrate deposit and methane is collected at a distant end.

The technique is somewhat similar in concept to one investigated in the early 2010s by Steven Bryant and others at the University of Texas. In addition to numerous methane hydrate deposits, the Gulf Coast has large pools of hot, salty brine in sedimentary rock under the coastline. In this system, pumps would send CO2 down into one end of a deposit, which would force brine into a pipe that is placed at the other end and leads back to the surface. There the hot brine would flow through a heat exchanger, where heat could be extracted and used for industrial processes or to generate electricity, supporting projects such as electrified LNG in some markets. The upwelling brine also contains some methane that could be siphoned off and burned. The CO2 dissolves into the underground brine, becomes dense and sinks further belowground, where it theoretically remains.

Either system faces big practical challenges, and building shared CO2 storage hubs to aggregate captured gas is still evolving. One is creating a concentrated flow of CO2; the gas makes up only .04 percent of air, and roughly 10 percent of the smokestack emission from a typical power plant or industrial facility. If an efficient methane hydrate or brine system requires an input that is 90 percent CO2, for example, concentrating the gas will require an enormous amount of energy—making the process very expensive. “But if you only need a 50 percent concentration, that could be more attractive,” says Bryant, who is now a professor of chemical and petroleum engineering at the University of Calgary. “You have to reduce the [CO2] capture cost.”

Another major challenge for the methane hydrate approach is how to collect the freed methane, which could simply seep out of the deposit through numerous cracks and in all directions. “What kind of well [and pipe] structure would you use to grab it?” Bryant asks.

Given these realities, there is little economic incentive today to use methane hydrates for sequestering CO2. But as concentrations rise in the atmosphere and the planet warms further, and as calls for an electric planet intensify, systems that could capture the gas and also provide energy or revenue to run the process might become more viable than techniques that simply pull CO2 from the air and lock it away, offering nothing in return.

US Power Grid Blackouts highlight aging infrastructure, rising outages, and declining reliability per DOE and NERC data, with weather-driven failures, cyberattack risk, and underinvestment stressing utilities, transmission lines, and modernization efforts.

Key Points

US power grid blackouts are outages caused by aging grid assets, severe weather, and cyber threats reducing reliability.

✅ DOE and NERC data show rising outage frequency and duration.

✅ Weather now drives 68-73% of major failures since 2008.

✅ Modernization, hardening, and cybersecurity investments are critical.

The United States power grid has more blackouts than any other country in the developed world, according to new data and U.S. blackout warnings that spotlight the country’s aging and unreliable electric system.

The data by the Department of Energy (DOE) and the North American Electric Reliability Corporation (NERC) shows that Americans face more power grid failures lasting at least an hour than residents of other developed nations.

And it’s getting worse.

Going back three decades, the US grid loses power 285 percent more often than it did in 1984, when record keeping began, International Business Times reported. The power outages cost businesses in the United States as much as $150 billion per year, according to the Department of Energy.

Customers in Japan lose power for an average of 4 minutes per year, as compared to customers in the US upper Midwest (92 minutes) and upper Northwest (214), University of Minnesota Professor Massoud Amin told the Times. Amin is director of the Technological Leadership Institute at the school.

The grid is becoming less dependable each year, he said.

“Each one of these blackouts costs tens of hundreds of millions, up to billions, of dollars in economic losses per event,” Amin said. “… We used to have two to five major weather events per year [that knocked out power], from the ‘50s to the ‘80s. Between 2008 and 2012, major outages caused by weather, reflecting extreme weather trends, increased to 70 to 130 outages per year. Weather used to account for about 17 to 21 percent of all root causes. Now, in the last five years, it’s accounting for 68 to 73 percent of all major outages.”

As previously reported by Off The Grid News, the power grid received a “D+” grade on its power grid report card from the American Society of Civil Engineers (ASCE) in 2013. The power grid grade card rating means the energy infrastructure is in “poor to fair condition and mostly below standard, with many elements approaching the end of their service life.” It further means a “large portion of the system exhibits significant deterioration” with a “strong risk of failure.”

“America relies on an aging electrical grid and pipeline distribution systems, some of which originated in the 1880s,” the 2013 ASCE report read. “Investment in power transmission has increased since 2005, but ongoing permitting issues, weather events, and limited maintenance have contributed to an increasing number of failures and power interruptions.”

As The Times noted, the US power grid as it exists today was built shortly after World War II, with the design dating back to Thomas Edison. While Edison was a genius, he and his contemporaries could not have envisioned all the strains the modern world would place upon the grid and the multitude of tech gadgets many Americans treat as an extension of their body. While the drain on the grid has advanced substantially, the infrastructure itself has not.

There are approximately 5 million miles of electrical transmission lines throughout the United States, and thousands of power generating plants dot the landscape. The electrical grid is managed by a group of 3,300 different utilities and serve about 150 million customers, The Times said. The entire power grid system is currently valued at $876 billion.

Many believe the grid is vulnerable to an attack on substations and other threats.

Former Department of Homeland Security Secretary Janet Napolitano once said that a power grid cyber attack is a matter of “when” not “if,” as Russians hacked utilities incidents have shown.

Ontario Comprehensive Electricity Plan delivers Global Adjustment reductions for industrial and commercial non-RPP customers, lowering electricity rates, shifting renewable energy costs, and enhancing competitiveness across Ontario businesses in 2022, with additional 4 percent savings.

Key Points

Ontario's plan lowers Global Adjustment by shifting renewable costs, cutting industrial and commercial bills 15-17%.

✅ Shifts above-market non-hydro renewable costs to the Province

✅ Reduces GA for industrial and commercial non-RPP customers

✅ Additional 4% savings on 2022 bills after GA deferral

As of January 1, 2022, industrial and commercial electricity customers will benefit from the full savings introduced through the Ontario government’s Comprehensive Electricity Plan, which supports stable electricity pricing for industrial and commercial companies, announced in Budget 2020, and first implemented in January 2021. This year customers could see an additional four percent savings compared to their bills last year, bringing the full savings from the Comprehensive Electricity Plan to between 15 and 17 per cent, making Ontario a more competitive place to do business.

“Our Comprehensive Electricity Plan has helped reverse the trend of skyrocketing electricity prices that drove jobs out of Ontario,” said Todd Smith, Minister of Energy. “Over 50,000 customers are benefiting from our government’s plan which has reduced electricity rates on clean and reliable power, allowing them to focus on reinvesting in their operations and creating jobs here at home.”

Starting on January 1, 2021, the Comprehensive Electricity Plan reduced overall Global Adjustment (GA) costs for industrial and commercial customers who do not participate in the Regulated Price Plan (RPP) by shifting the forecast above-market costs of non-hydro renewable energy, such as wind, solar and bioenergy, from the rate base to the Province, alongside energy-efficiency programs that complement demand reduction efforts.

“Since taking office, our government has listened to job creators and worked to lower the costs of doing business in the province. Through these significant reductions in electricity prices through the Comprehensive Electricity Plan, customers all across Ontario will benefit from significant savings in their business operations in 2022,” said Vic Fedeli, Minister of Economic Development, Job Creation and Trade. “By continuing to reduce electricity costs, lowering taxes, and cutting red tape our government has reduced the cost of doing business in Ontario by nearly $7 billion annually to ensure that we remain competitive, innovative and poised for economic recovery.”

As part of its COVID response, including electricity relief for families and small businesses, Ontario had deferred a portion of GA between April and June 2020 for industrial and non-RPP commercial customers, with more than 50,000 customers benefiting. Those same businesses paid back these deferred GA costs over 12 months, between January 2021 and December 2021, while the province prepared to extend disconnect moratoriums for residential customers.

During the pandemic, residential electricity use rose even as overall consumption dropped, underscoring shifts in load patterns.

Now that the GA deferral repayment period is over, industrial and non-RPP commercial customers will benefit from the full cost reductions provided to them by the Comprehensive Electricity Plan, alongside temporary off-peak rate relief that supported families and small businesses. This means that, beginning January 1, 2022, these businesses could see an additional four per cent savings on their bills compared to 2021, as new ultra-low overnight pricing options emerge depending on their location and consumption.

Manitoba Hydro Phone Scam targets small businesses with disconnection threats, prepaid card payments, caller ID spoofing, phishing texts, and door-to-door fraud; hang up, verify your account directly, and never share banking information.

Key Points

A scam where callers threaten disconnection and demand prepaid cards; verify account status directly with Manitoba Hydro.

✅ Hang up and call Manitoba Hydro at 1-888-624-9376 to verify.

✅ Never pay by prepaid cards, gift cards, or crypto.

✅ Hydro will not cut power on one-hour notice.

Manitoba Hydro is warning customers, particularly small business owners, to be wary of high-pressure scammers, as Ontario utilities warn of scams in other provinces, threatening to shut off their electricity.

The callers demand the customer to make immediate payment by a prepaid card. Often, the calls are made in the middle of the day at a busy time, frightening the customer with aggressive threats about disconnection, as hydro disconnections have made headlines elsewhere, says hydro spokesman Bruce Owen.

"They tell them 'we have a truck on the way to cut off your power. If you don't pay in the next hour you're out of luck,'" he said.

"And because these folks have inventory in freezers and they have customers … they're willing to fork over several hundred or even several thousand dollars on a prepaid card to somebody they don't know to keep the lights on."

Maybe the business owners can't recall, with everything happening, including discussions about Hydro One peak rates in Ontario, if they've made their payments on time. They start second-guessing and believing the person on the other line, Owen says.

And they worry about losing thousands of dollars in business if they lose power. So they're more than willing to run out to a store, buy a prepaid debit card and provide the number to the caller.

"Their goal is to manipulate you into sending money before you figure out it's a scam," said Chris McColm, hydro's security and investigations supervisor. "These people are crooks and you should hang up on them."

For any customers that are in arrears, hydro will work with them to resolve the issue, Owen said.

"We do not have to take that extreme measure of cutting off or disconnecting anybody. That's not the business we're in — we don't strong arm people that way," he said.

"Anybody who's threatening to cut off your power with an hour or half-an-hour notice, well it's it's no better than someone waiting around the corner, waiting the club you over the head in the dark of night. That's what they are."

Fraud reports soar

The power utility has recorded a nearly-300 per cent jump in the number of fraud-related complaints this year over 2017. There have been 862 phone, text and e-mail scams and that could still go much higher.

The current statistics from 2018 have only calculated up to Oct. 31. In 2017, there were 221.

That jump in numbers doesn't necessarily mean there are more scammers out there.

It could simply mean people are finally getting wise to fraudsters and reporting it more, Owen says.

"At the same token, we don't hear of everybody who's been taking advantage of because once they've found out that they've been hoodwinked they don't want to tell anybody because they're so embarrassed," he said.

"These scammers can be very convincing and anyone can be victimized," McColm said.

If you are able to think clearly when some high-pressure caller gets you on the line, Owen suggests asking a few simple questions to challenge their legitimacy:

• What street am I on?
• What does my business look like? 
• What's the weather outside right now?

Phone scammers can falsify their caller ID information to make it appear they're calling from a local number, but what you'll find is most of them aren't in Winnipeg or Manitoba and likely not even this country or continent, Owen says.

The key to being safe is simply to never give out banking information, Owen says. It's a message that has been stressed for years and 80-90 per cent of people understand it, but it's that other 10-20 per cent that are still being victimized.And it's not just phone calls. Many other fraud-related complaints to Manitoba Hydro this year concerned unsolicited text messages to customers saying they had been overbilled, or faced retroactive charges elsewhere, and were eligible for a refund.

This scam is also aimed at getting a customer's personal banking information, under the guise of having money put back into their account.

Also, many people, especially seniors living alone, continue to be targeted by aggressive door-to-door fraudsters, and cases like the electricity theft ring in Montreal underscore the risks, McColm says. However, he adds, hydro employees always display photo ID and will never demand to come into a home. 

If you're unsure whether a phone call, text or email is real or a scam, contact Manitoba Hydro at 1-888-624-9376.

UK power grid bottleneck is stalling renewable energy, with connection queues, planning delays, and transmission infrastructure gaps raising costs, slowing decarbonization, and deterring investment as government considers reforms led by a new chief adviser.

Key Points

Delays and capacity gaps that hinder connecting new generation and demand, raising costs and slowing decarbonization.

✅ Connection queues delay projects for years

✅ Planning and NIMBY barriers stall transmission builds

✅ Investment costs on bills risk political pushback

During his three decades at investment bank Morgan Stanley, Franck Petitgas developed a reputation for solving problems that vexed others. Fixing the UK’s creaking power grid could be his most challenging task yet.

Earlier this year, Prime Minister Rishi Sunak appointed Petitgas as his chief business adviser, and the former financier has been pushing to tackle the gridlock that’s left projects waiting endlessly for a connection, an issue he sees as one of the biggest problems for industry.

But there are no easy solutions to tackle the years-long queue to get on the grid or the drawn-out planning process for building clean power generation, with the energy transition stalled by supply delays compounding the problem. And sluggish progress in expanding and improving the electricity network is preventing the construction of new housing developments and offices, as well as slowing the transition to greener power.

That transition has already taken a knock after Sunak last week controversially watered down some of the UK’s climate ambitions, citing in part the cost to consumers. He also acknowledged the issues surrounding the grid and promised the “most transformative plans” in response, drawing on lessons from Europe’s power crisis where applicable. Those are due to be unveiled within weeks. 

Shortly after his appointment, Petitgas offered reassurances to business leaders at a meeting in Downing Street that solutions were being worked on, according to people familiar with the matter. But there’s a lack of confidence across business that enough will be done.

Cost is a big factor in the expansion of the electricity grid, and some argue a state-owned generation model could ease bills over time. Improving the onshore network alone could require investment of between £100 billion and £240 billion ($122-$293 billion) by 2050, according to a government analysis last year. 

With network expansion funded through power bills, that’s a big ask, particularly with Sunak trailing in polls ahead of an election expected next year.

“It’s very difficult for politicians to say more money should be on bills,” said Emma Pinchbeck, chief executive of Energy UK, a trade body. “So you get to a situation where no one wants to pay for the infrastructure investment until it’s really sticky, and that’s where we’ve got to with the grid.”

There are huge competitive and economic implications if the UK falls further behind. With US President Joe Biden spending an estimated $370 billion on climate measures through his Inflation Reduction Act, and China already a world leader in electric vehicles, Britain’s grid inaction is holding it back in the global race to decarbonize, said Jess Ralston, an analyst at the Energy and Climate Intelligence Unit think tank.

“The UK is dithering and delaying, and not making any strategic decisions,” she said. “You can see companies just saying ‘I’m going to the US, or I’m going to China’.” 

In a statement, the government said it’s a “priority to speed up the time taken to connect new power generators and power consumers to the grid.” It added that it’s taking “significant steps to accelerate grid infrastructure,” including support for new Channel interconnectors announced this year.

The government expects demand for electricity to double by 2035 and that will mean more generation that needs to be linked up to the network by cables and pylons. Local grids will also have to expand to accommodate more connection points for electric vehicles and homes, and invest in large-scale energy storage capacity to balance supply.

But so far, the rapid rise in renewable energy investment has not been accompanied by matching spend on the power network, according to BloombergNEF, a pattern seen in Germany’s grid expansion woes as well.

“The pace and scale of what we now have to deliver is significantly different from the last few decades,” said Carl Trowell, president of UK strategic infrastructure at National Grid. “It’s a national endeavor.”

In June, Electricity Networks Commissioner Nick Winser sent the government recommendations for how to accelerate construction of more transmission infrastructure. He said efforts to decarbonize the power sector will be “wasted if we cannot get the power to homes and businesses.”

“We need a seriously stronger sense of urgency,” said Kevin O’Donovan, country manager for Statkraft UK, which is holding off investment in four wind farms and two solar projects due to grid connection delays.

In addition to cost, the other major stumbling block is planning. Politicians in the governing Conservative Party are wary of angering voters with new infrastructure in rural areas that typically vote Tory. Across the country, “Not In My Back Yard” campaigners – NIMBYs — pose a major challenge to projects.

Petitgas, 62, retired from Morgan Stanley last year after nearly 30 years at the bank, where he led its international division from London. The issues over connections and planning have been repeatedly pointed out to Petitgas by investors and trade groups over a series of meetings this year, according to people familiar with the matter, requesting anonymity discussing private talks.

Yet with a general election looming and the issue plagued by political headaches, many are skeptical that Sunak can find the solutions needed.

One business chief said Downing Street considers the issue too tricky and expensive to tackle in the short-term. Others are concerned that while Petitgas has license from Sunak, he doesn’t have influence across the relevant departments to get grids to the top of the agenda.

Wind Farms

Multiple parts of the UK’s climate plans are under pressure. Earlier this month, an auction for contracts to build new wind farms received zero bids from developers, even as wind leads the power mix in many regions, marking yet another green setback. 

The UK is already behind on its target of having 50 gigawatts of offshore wind built by 2030, up from 14 GW today. The challenge is accelerating development without railroading local communities.

Within Sunak’s Conservative Party, some lawmakers are pushing back on new infrastructure in their local areas. A group including Environment Secretary Therese Coffey and former Home Secretary Priti Patel is campaigning against building new pylons across a stretch of eastern England.

According to Adam Bell, director of policy at consultancy Stonehaven, backbench pressure means Sunak is unlikely to take major action on the grid in the near term. He doesn’t see the prime minister accepting Winser’s recommendations, least of all accelerating planning decisions.

“Over the last year, Sunak has favored party management over things that will benefit the country,” Bell said.

Rising Greenhouse Gas Concentrations drive climate change, with CO2, methane, and nitrous oxide surging; WMO data show higher radiative forcing, elevated pre-industrial baselines, and persistent atmospheric concentrations despite Paris Agreement emissions pledges.

Key Points

Increasing atmospheric CO2, methane, and nitrous oxide levels that raise radiative forcing and drive warming.

✅ WMO data show CO2 at 407.8 ppm in 2018, above decade average

✅ Methane and nitrous oxide surged, elevating total radiative forcing

✅ Concentrations differ from emissions; sinks absorb about half

The World Meteorological Organization (WMO) says the increase in CO2 was just above the average rise recorded over the last decade.

Levels of other warming gases, such as methane and nitrous oxide, have also surged by above average amounts.

Since 1990 there's been an increase of 43% in the warming effect on the climate of long lived greenhouse gases.

The WMO report looks at concentrations of warming gases in the atmosphere rather than just emissions.

The difference between the two is that emissions refer to the amount of gases that go up into the atmosphere from the use of fossil fuels, such as burning coal for coal-fired electricity generation and from deforestation.

Concentrations are what's left in the air after a complex series of interactions between the atmosphere, the oceans, the forests and the land. About a quarter of all carbon emissions are absorbed by the seas, and a similar amount by land and trees, while technologies like carbon capture are being explored to remove CO2.

Using data from monitoring stations in the Arctic and all over the world, researchers say that in 2018 concentrations of CO2 reached 407.8 parts per million (ppm), up from 405.5ppm a year previously.

This increase was above the average for the last 10 years and is 147% of the "pre-industrial" level in 1750.

The WMO also records concentrations of other warming gases, including methane and nitrous oxide, and some countries have reported declines in certain potent gases, as noted in US greenhouse gas controls reports, though global levels remain elevated. About 40% of the methane emitted into the air comes from natural sources, such as wetlands, with 60% from human activities, including cattle farming, rice cultivation and landfill dumps.

Methane is now at 259% of the pre-industrial level and the increase seen over the past year was higher than both the previous annual rate and the average over the past 10 years.

Nitrous oxide is emitted from natural and human sources, including from the oceans and from fertiliser-use in farming. According to the WMO, it is now at 123% of the levels that existed in 1750.

Last year's increase in concentrations of the gas, which can also harm the ozone layer, was bigger than the previous 12 months and higher than the average of the past decade.

What concerns scientists is the overall warming impact of all these increasing concentrations. Known as total radiative forcing, this effect has increased by 43% since 1990, and is not showing any indication of stopping.

There is no sign of a slowdown, let alone a decline, in greenhouse gases concentration in the atmosphere despite all the commitments under the Paris agreement on climate change and the ongoing global energy transition efforts," said WMO Secretary-General Petteri Taalas.

"We need to translate the commitments into action and increase the level of ambition for the sake of the future welfare of mankind," he added.

"It is worth recalling that the last time the Earth experienced a comparable concentration of CO2 was three to five million years ago. Back then, the temperature was 2-3C warmer, sea level was 10-20m higher than now," said Mr Taalas.

The UN Environment Programme will report shortly on the gap between what actions countries are taking to cut carbon, for example where Australia's emissions rose 2% recently, and what needs to be done to keep under the temperature targets agreed in the Paris climate pact.

Preliminary findings from this study, published during the UN Secretary General's special climate summit last September, indicated that emissions continued to rise during 2018, although global emissions flatlined in 2019 according to the IEA.

Both reports will help inform delegates from almost 200 countries who will meet in Madrid next week for COP25, following COP24 in Katowice the previous year, the annual round of international climate talks.
