UK Hydrogen Storage Caverns enable long-duration, low-carbon electricity balancing, storing surplus wind and solar power as green hydrogen in salt formations to enhance grid reliability, energy security, and net zero resilience by 2035 and 2050.

Key Points

They are salt caverns storing green hydrogen to balance wind and solar, stabilizing a low-carbon UK grid.

✅ Stores surplus wind and solar as green hydrogen in salt caverns

✅ Enables long-duration, low-carbon grid balancing and security

✅ Complements wind and solar; reduces dependence on flexible CCS

The U.K. government must kick-start the construction of large-scale hydrogen storage facilities if it is to meet its pledge that all electricity will come from low-carbon electricity sources by 2035 and reach legally binding net zero targets by 2050, according to a report by the Royal Society.

The report, "Large-scale electricity storage," published Sep. 8, examines a wide variety of ways to store surplus wind and solar generated electricity—including green hydrogen, advanced compressed air energy storage (ACAES), ammonia, and heat—which will be needed when Great Britain's electricity generation is dominated by volatile wind and solar power.

It concludes that large scale electricity storage is essential to mitigate variations in wind and sunshine, particularly long-term variations in the wind, and to keep the nation's lights on. Storing most of the surplus as hydrogen, in salt caverns, would be the cheapest way of doing this.

The report, based on 37 years of weather data, finds that in 2050 up to 100 Terawatt-hours (TWh) of storage will be needed, which would have to be capable of meeting around a quarter of the U.K.'s current annual electricity demand. This would be equivalent to more than 5,000 Dinorwig pumped hydroelectric dams. Storage on this scale, which would require up to 90 clusters of 10 caverns, is not possible with batteries or pumped hydro.

Storage requirements on this scale are not currently foreseen by the government, and the U.K.'s energy transition faces supply delays. Work on constructing these caverns should begin immediately if the government is to have any chance of meeting its net zero targets, the report states.

Sir Chris Llewellyn Smith FRS, lead author of the report, said, "The need for long-term storage has been seriously underestimated. Demand for electricity is expected to double by 2050 with the electrification of heat, transport, and industrial processing, as well as increases in the use of air conditioning, economic growth, and changes in population.

"It will mainly be met by wind and solar generation. They are the cheapest forms of low-carbon electricity generation, but are volatile—wind varies on a decadal timescale, so will have to be complemented by large scale supply from energy storage or other sources."

The only other large-scale low-carbon sources are nuclear power, gas with carbon capture and storage (CCS), and bioenergy without or with CCS (BECCS). While nuclear and gas with CCS are expected to play a role, they are expensive, especially if operated flexibly.

Sir Peter Bruce, vice president of the Royal Society, said, "Ensuring our future electricity supply remains reliable and resilient will be crucial for our future prosperity and well-being. An electricity system with significant wind and solar generation is likely to offer the lowest cost electricity but it is essential to have large-scale energy stores that can be accessed quickly to ensure Great Britain's energy security and sovereignty."

Combining hydrogen with ACAES, or other forms of storage that are more efficient than hydrogen, could lower the average cost of electricity overall, and would lower the required level of wind power and solar supply.

There are currently three hydrogen storage caverns in the U.K., which have been in use since 1972, and the British Geological Survey has identified the geology for ample storage capacity in Cheshire, Wessex and East Yorkshire. Appropriate, novel business models and market structures will be needed to encourage construction of the large number of additional caverns that will be needed, the report says.

Sir Chris observes that, although nuclear, hydro and other sources are likely to play a role, Britain could in principle be powered solely by wind power and solar, supported by hydrogen, and some small-scale storage provided, for example, by batteries, that can respond rapidly and to stabilize the grid. While the cost of electricity would be higher than in the last decade, we anticipate it would be much lower than in 2022, he adds.

Millstone COVID-19 safety concerns center on a nuclear refueling outage in Connecticut, temporary workers, OSHA complaints, PPE shortages, and disinfecting protocols, as Dominion Energy addresses virus precautions, staffing, and cybersecurity for safe voting infrastructure.

Key Points

Employee and union claims about PPE, cleaning, and OSHA compliance during a refueling outage at the nuclear plant.

✅ 10 positive cases; 750 temporary workers during refueling outage

✅ Union cites PPE gaps, partitions, and disinfectant effectiveness

✅ Dominion Energy notes increased cleaning, communication, staffing

Workers at Connecticut's only nuclear power plant worry that managers are not taking enough precautions against the coronavirus, as some utilities weigh on-site staffing measures to maintain operations, after 750 temporary employees were brought in to help refuel one of the two active reactors.

Ten employees at the Millstone Power Station in Waterford have tested positive for the virus, and, amid a U.S. grid pandemic warning, the arrival of the temporary workers alarms some of the permanent employees, The Day newspaper reported Sunday.

"Speaking specifically for the guard force, there's a lot of frustration, there's a lot of concern, and I would say there's anger," said Millstone security officer Jim Foley.

Foley, vice president of the local chapter of the United Government Security Officers of America, noted broader labor concerns such as unpaid wages for Kentucky miners while saying security personnel have had to fight for personal protective equipment and for partitions at access points to separate staff from security.

Foley also has filed a complaint with the Occupational Safety and Health Administration saying Millstone staff are using ineffective cleaning materials and citing a lack of cleaning and sanitizing, as telework limits at the EPA drew scrutiny during the pandemic, he said.

Officials at Millstone, owned by Dominion Energy, have not heard internal criticism about the plant's virus precautions, Millstone spokesman Kenneth Holt said.

"We've actually gotten a lot of compliments from employees on the steps we've taken," he said. "We've stepped up communications with employees to let them know what's going on."

As another example of communication efforts, COVID-19 updates at Site C have been published to keep workers informed.

Millstone recently increased cleaning staff on the weekends, Holt said, and there is regular disinfecting at the plant.

Separately, utility resilience remains a concern, as extended outages for tornado survivors in Kentucky may last weeks, affecting essential services.

Responding to the complaint about ineffective cleaning materials, Holt said staff members early in the pandemic went to a Home Depot and got a bottle of disinfectant that wasn't approved by the federal government as effective against the coronavirus. An approved disinfectant was brought in the next day, he said.

The deaths of nearly 2,500 Connecticut residents have been linked to COVID-19, the disease caused by the virus. More than 29,000 state residents have tested positive. As of Sunday, hospitalizations had declined for 11 consecutive days, to over 1,480.

With more people working remotely, utilities have reported higher residential electricity use during the pandemic, affecting household bills.

For most people, the coronavirus causes mild or moderate symptoms, such as fever and cough, that clear up in two to three weeks. For some, especially older adults and people with existing health problems, it can cause more severe illness, including pneumonia, and death.

In other developments related to the coronavirus:

SAFE VOTING

Secretary of the State Denise Merrill released a plan Monday aimed at making voting safe during the Aug. 11 primary and Nov. 3 general election.

Merrill said her office is requiring all cities and towns in the state to submit plans for the two elections that include a list of cleaning and safety products to be used, a list of polling locations, staffing levels at each polling location, and the names of polling workers and moderators.

Municipalities will be eligible for grants to cover the extra costs of holding elections during a pandemic, including expenses for cleaning products and increased staffing.

Merrill also announced her office and the Connecticut National Guard will perform a high-level cybersecurity assessment of the election infrastructure of all 169 towns in the state to guard against malicious actors.

Merrill's office also will provide network upgrades to the election infrastructures of 20 towns that have had chronic problems with connecting to the elections system.

ERCOT Texas Fall Grid Forecast outlines ample power supply, planned maintenance outages, and grid reliability, citing PUC oversight and Gov. Abbott's remarks, with seasonal assessment noting mild demand yet climate risks and conservation alerts.

Key Points

ERCOT's seasonal outlook for Texas on fall power supply, outages, and reliability expectations under PUC oversight.

✅ Projects sufficient supply in October and November

✅ Many plants scheduled offline for maintenance

✅ Notes PUC oversight and Abbott's confidence

Gov. Greg Abbott said Tuesday that the Texas power grid is prepared for the fall months and referenced a new seasonal forecast by the state’s grid operator, which typically does not draw much attention to its fall and spring grid assessments because of the more mild temperatures during those seasons.

Tuesday’s new forecast by the Electric Reliability Council of Texas showed that there should be plenty of power supply to meet demand in October and November. It also showed that many Texas power plants are scheduled to be offline this fall for maintenance work. Texas power plants usually plan to go down in the fall and spring for repairs to improve reliability ahead of the more extreme temperatures in winter and summer, when Texans crank up their heat and air conditioning and raise demand for power.

ERCOT for at least a decade announced its seasonal forecasts, but did not do so on Tuesday. The grid operator stopped announcing the reports after the 2021 winter storm event. A spokesperson for the grid operator, which posted the report to its website midday without notifying the public or power industry stakeholders, said there were no plans to discuss the latest forecast and referred questions about it to the Public Utility Commission, which oversees ERCOT. Abbott appoints the board of the PUC.

Abbott on Tuesday expressed his confidence about the grid in a news release, which included photos of the governor sitting at a table with incoming ERCOT CEO Pablo Vegas, outgoing interim CEO Brad Jones and Public Utility Commission Chair Peter Lake.

“The State of Texas continues to monitor the reliability of our electric grid, and I thank ERCOT and PUC for their hard work to implement bipartisan reforms we passed last year and for their proactive leadership to ensure our grid is stronger than ever before,” Abbott said in the release.

Abbott has not previously shared or called attention to ERCOT’s forecasts as he did on Tuesday.

Up for reelection this fall, Abbott has faced continued criticism, including from the Sierra Club over his handling of the 2021 deadly power grid disaster, when extended freezing temperatures shut down natural gas facilities and power plants, which rely on each other to keep electricity flowing. The resulting blackouts left millions of Texans without power for days in the cold, and hundreds of people died.

ERCOT’s forecasts for fall and spring are typically the least worrisome seasonal forecasts, energy experts said, because temperatures are usually milder in between summer and winter, even as ERCOT has issued an RFP to procure winter capacity to address shortages, so demand for power usually does not skyrocket like it does during extreme temperatures.

But they’ve warned that climate change could potentially lead to more extreme temperatures during times when Texas hasn’t experienced such weather in the past. For example, in early May six power plants unexpectedly broke down when a spring heat wave drove power demand up and highlighted broader heat-related blackout risks across the grid. ERCOT asked Texans to conserve electricity at home at the time.

Abbott released the seasonal report at a time when he has asserted unprecedented control over ERCOT. Although he had no formal role in ERCOT’s search for a new permanent CEO, he put a stranglehold on the process, The Texas Tribune previously reported. Since the winter storm, Abbott’s office has also dictated what information about the power grid ERCOT has released to the public.

Texas Blackout Liability Ruling clarifies appellate court findings in Houston, citing deregulated energy markets, ERCOT immunity, wholesale generators, retail providers, and 2021 winter storm lawsuits over grid failures and wrongful deaths.

Key Points

Houston judges held wholesale generators owe no duty to retail customers, limiting liability for 2021 blackout lawsuits.

✅ Court cites deregulated market and lack of privity to consumers

✅ Ruling shields generators from 2021 winter storm civil suits

✅ Plaintiffs plan appeals; legislature may address liability

Nearly three years after the devastating Texas blackout of 2021, a panel of judges from the First Court of Appeals in Houston has determined that major power companies cannot be held accountable for their failure to deliver electricity during the power grid crisis that unfolded, citing Texas' deregulated energy market as the reason.

This ruling appears likely to shield these companies from lawsuits that were filed against them in the aftermath of the blackout, leaving the families of those affected uncertain about where to seek justice.

In February 2021, a severe cold front swept over Texas, bringing extended periods of ice and snow. The extreme weather conditions increased energy demand while simultaneously reducing supply by causing power generators and the state's natural gas supply chain to freeze. This led to a blackout that left millions of Texans without power and water for nearly a week.

The state officially reported that almost 250 people lost their lives during the winter storm and subsequent blackout, although some analysts argue that this is a significant undercount and warn of blackout risks across the U.S. during severe heat as well.

In the wake of the storm, Texans affected by the energy system's failure began filing lawsuits, and lawmakers proposed a market bailout as political debate intensified. Some of these legal actions were directed against power generators whose plants either ceased to function during the storm or ran out of fuel for electricity generation.

After several years of legal proceedings, a three-judge panel was convened to evaluate the merits of these lawsuits.

This week, Chief Justice Terry Adams issued a unanimous opinion on behalf of the panel, stating, "Texas does not currently recognize a legal duty owed by wholesale power generators to retail customers to provide continuous electricity to the electric grid, and ultimately to the retail customers."

The opinion further clarified that major power generators "are now statutorily precluded by the legislature from having any direct relationship with retail customers of electricity."

This separation of power generation from transmission and retail electric sales in many parts of Texas resulted from energy market deregulation in the early 2000s, with the goal of reducing energy costs, and prompted electricity market reforms aimed at avoiding future blackouts.

Under the previous system, power companies were "vertically integrated," controlling generators, transmission lines, and selling the energy they produced directly to regional customers. However, in deregulated areas of Texas, competition was introduced, creating competing energy-generating companies and retail electric providers that purchase power wholesale and then sell it to residential consumers; meanwhile, electric cooperatives in other parts of the state remained member-owned providers.

Tré Fischer, a partner at the Jackson Walker law firm representing the power companies, explained, "One consequence of that was, because of the unbundling and the separation, you also don't have the same duties and obligations [to consumers]. The structure just doesn't allow for that direct relationship and correspondingly a direct obligation to continually supply the electricity even if there's a natural disaster or catastrophic event."

In the opinion, Justice Adams noted that when designing the Texas energy market, amid renewed interest in ways to improve electricity reliability across the grid, state lawmakers "could have codified the retail customers' asserted duty of continuous electricity on the part of wholesale power generators into law."

The recent ruling applies to five representative cases chosen by the panel out of hundreds filed after the blackout. Due to this decision, it is improbable that any of the lawsuits against power companies will succeed, according to the court's interpretation.

However, plaintiffs' attorneys have indicated their intention to appeal. They may request a review of the panel's opinion by the entire First Court of Appeals or appeal directly to the state supreme court.

The state Supreme Court had previously ruled that the Electric Reliability Council of Texas (ERCOT), the state's power grid operator, enjoys sovereign immunity and cannot be sued over the blackout.

This latest opinion raises the question of who, if anyone, can be held responsible for deaths and losses resulting from the blackout, a question left unaddressed by the court. Fischer commented, "If anything [the judges] were saying that is a question for the Texas legislature."

Advanced Traffic Light System for Geothermal Safety models fracture growth and friction with rock physics, geophones, and supercomputers to predict induced seismicity during hydraulic stimulation, enabling real-time risk control for ETH Zurich and SED.

Key Points

ATLS uses rock physics, geophones, and HPC to forecast induced seismicity in real time during geothermal stimulation.

✅ Real-time seismic risk forecasts during hydraulic stimulation

✅ Uses rock physics, friction, and fracture modeling on HPC

✅ Supports ETH Zurich and SED field tests in Iceland and Bedretto

The Swiss Earthquake Service and ETH Zurich want to make geothermal energy safer, so news piece from Switzerland earlier this month. This is to be made possible by new software, including machine learning, and the computing power of supercomputers. The first geothermal tests have already been carried out in Iceland, and more will follow in the Bedretto laboratory.

In areas with volcanic activity, the conditions for operating geothermal plants are ideal. In Iceland, the Hellisheidi power plant makes an important contribution to sustainable energy use, alongside innovations like electricity from snow in cold regions.

Deep geothermal energy still has potential. This is the basis of the 2050 energy strategy. While the inexhaustible source of energy in volcanically active areas along fault zones of the earth’s crust can be tapped with comparatively little effort and, where viable, HVDC transmission used to move power to demand centers, access on the continents is often much more difficult and risky. Because the geology of Switzerland creates conditions that are more difficult for sustainable energy production.

Improve the water permeability of the rock

On one hand, you have to drill four to five kilometers deep to reach the correspondingly heated layers of earth in Switzerland. It is only at this depth that temperatures between 160 and 180 degrees Celsius can be reached, which is necessary for an economically usable water cycle. On the other hand, the problem of low permeability arises with rock at these depths. “We need a permeability of at least 10 millidarcy, but you can typically only find a thousandth of this value at a depth of four to five kilometers,” says Thomas Driesner, professor at the Institute of Geochemistry and Petrology at ETH Zurich.

In order to improve the permeability, water is pumped into the subsurface using the so-called “fracture”. The water acts against friction, any fracture surfaces shift against each other and tensions are released. This hydraulic stimulation expands fractures in the rock so that the water can circulate in the hot crust. The fractures in the earth’s crust originate from tectonic tensions, caused in Switzerland by the Adriatic plate, which moves northwards and presses against the Eurasian plate.

In addition to geothermal energy, the “Advanced Traffic Light System” could also be used in underground construction or in construction projects for the storage of carbon dioxide.

Quake due to water injection

The disadvantage of such hydraulic stimulations are vibrations, which are often so weak or cannot be perceived without measuring instruments. But that was not the case with the geothermal projects in St. Gallen 2013 and Basel 2016. A total of around 11,000 cubic meters of water were pumped into the borehole in Basel, causing the pressure to rise. Using statistical surveys, the magnitudes 2.4 and 2.9 defined two limit values ??for the maximum permitted magnitude of the earthquakes generated. If these are reached, the water supply is stopped.

In Basel, however, there was a series of vibrations after a loud bang, with a time delay there were stronger earthquakes, which startled the residents. In both cities, earthquakes with a magnitude greater than 3 have been recorded. Since then it has been clear that reaching threshold values ??determines the stop of the water discharge, but this does not guarantee safety during the actual drilling process.

Simulation during stimulation

The Swiss Seismological Service SED and the ETH Zurich are now pursuing a new approach that can be used to predict in real time, building on advances by electricity prediction specialists in Europe, during a hydraulic stimulation whether noticeable earthquakes are expected in the further course. This is to be made possible by the so-called “Advanced Traffic Light System” based on rock physics, a software developed by the SED, which carries out the analysis on a high-performance computer.

Geophones measure the ground vibrations around the borehole, which serve as indicators for the probability of noticeable earthquakes. The supercomputer then runs through millions of possible scenarios, similar to algorithms to prevent power blackouts during ransomware attacks, based on the number and type of fractures to be expected, the friction and tensions in the rock. Finally, you can filter out the scenario that best reflects the underground.

Further tests in the mountain

However, research is currently still lacking any real test facility for the system, because incorrect measurements must be eliminated and a certain data format adhered to before the calculations on the supercomputer. The first tests were carried out in Iceland last year, with more to follow in the Bedretto geothermal laboratory in late summer, where reliable backup power from fuel cell solutions can keep instrumentation running. An optimum can now be found between increasing the permeability of rock layers and an adequate water supply.

The new approach could make geothermal energy safer and ultimately help this energy source to become more accepted, while grid upgrades like superconducting cables improve efficiency. Research also sees areas of application wherever artificially caused earthquakes can occur, such as in underground mining or in the storage of carbon dioxide underground.

Netherlands vs Canada Solar Power compares per capita capacity, renewable energy policies, photovoltaics adoption, rooftop installations, grid integration, and incentives like feed-in tariffs and BIPV, highlighting efficiency, costs, and public engagement.

Key Points

Concise comparison of per capita capacity, policies, technology, and engagement in Dutch and Canadian solar adoption.

✅ Dutch per capita PV capacity exceeds Canada's by wide margin.

✅ Strong incentives: net metering, feed-in tariffs, rooftop focus.

✅ Climate, grid density, and awareness drive higher yields.

When it comes to harnessing solar power, the Netherlands stands as a shining example of efficient and widespread adoption, far surpassing Canada in solar energy generation per capita. Despite Canada's vast landmass and abundance of sunlight, the Netherlands has managed to outpace its North American counterpart, which some experts call a solar power laggard in solar energy production. This article explores the factors behind the Netherlands' success in solar power generation and compares it to Canada's approach.

Solar Power Capacity and Policy Support

The Netherlands has rapidly expanded its solar power capacity in recent years, driven by a combination of favorable policies, technological advancements, and public support. According to recent data, the Netherlands boasts a significantly higher per capita solar power capacity compared to Canada, where demand for solar electricity lags relative to deployment in many regions, leveraging its smaller geographical size and dense population centers to maximize solar panel installations on rooftops and in urban areas.

In contrast, Canada's solar energy development has been slower, despite having vast areas of suitable land for solar farms. Challenges such as regulatory hurdles, varying provincial policies, and the high initial costs of solar installations have contributed to a more gradual adoption of solar power across the country. However, provinces like Ontario have seen significant growth in solar installations due to supportive government incentives and favorable feed-in tariff programs, though growth projections were scaled back after Ontario scrapped a key program.

Innovation and Technological Advancements

The Netherlands has also benefited from ongoing innovations in solar technology and efficiency improvements. Dutch companies and research institutions have been at the forefront of developing new solar panel technologies, improving efficiency rates, and exploring innovative applications such as building-integrated photovoltaics (BIPV). These advancements have helped drive down the cost of solar energy and increase its competitiveness with traditional fossil fuels.

In contrast, while Canada has made strides in solar technology research and development, commercialization and widespread adoption have been more restrained due to factors like market fragmentation and the country's reliance on other energy sources such as hydroelectricity.

Public Awareness and Community Engagement

Public awareness and community engagement play a crucial role in the Netherlands' success in solar power adoption. The Dutch government has actively promoted renewable energy through public campaigns, educational programs, and financial incentives for homeowners and businesses to install solar panels. This proactive approach has fostered a culture of energy conservation and sustainability among the Dutch population.

In Canada, while there is growing public support for renewable energy, varying levels of awareness and engagement across different provinces have impacted the pace of solar energy adoption. Provinces like British Columbia and Alberta have seen increasing interest in solar power, driven by environmental concerns, technological advancements, and economic benefits, as the country is set to hit 5 GW of installed capacity in the near term.

Climate and Geographic Considerations

Climate and geographic considerations also influence the disparity in solar power generation between the Netherlands and Canada. The Netherlands, despite its northern latitude, benefits from relatively mild winters and a higher average annual sunlight exposure compared to most regions of Canada. This favorable climate has facilitated higher solar energy yields and made solar power a more viable option for electricity generation.

In contrast, Canada's diverse climate and geography present unique challenges for solar energy deployment. Northern regions experience extended periods of darkness during winter months, limiting the effectiveness of solar panels in those areas. Despite these challenges, advancements in energy storage technologies and hybrid solar-diesel systems are making solar power increasingly feasible in remote and off-grid communities across Canada, even as Alberta faces expansion challenges related to grid integration and policy.

Future Prospects and Challenges

Looking ahead, both the Netherlands and Canada face opportunities and challenges in expanding their respective solar power capacities. In the Netherlands, continued investments in solar technology, grid infrastructure upgrades, and policy support will be crucial for maintaining momentum in renewable energy development.

In Canada, enhancing regulatory consistency, scaling up solar installations in urban and rural areas, and leveraging emerging technologies will be essential for narrowing the gap with global leaders in solar energy generation and for seizing opportunities in the global electricity market as the energy transition accelerates.

In conclusion, while the Netherlands currently generates more solar power per capita than Canada, with the Prairie Provinces poised to lead growth in the Canadian market, both countries have unique strengths and challenges in their pursuit of a sustainable energy future. By learning from each other's successes and leveraging technological advancements, both nations can further accelerate the adoption of solar power and contribute to global efforts to combat climate change.
