Wind energy may be used in nuclear facility

Siemens Gamesa SG 14-222 DD advances offshore wind with a 14 MW direct-drive turbine, 108 m blades, a 222 m rotor, optional 15 MW boost, powering about 18,000 homes; prototype 2021, commercial launch 2024.

Key Points

A 14 MW offshore wind turbine with 108 m blades and a 222 m rotor, upgradable to 15 MW, targeting commercial use in 2024.

✅ 14 MW direct-drive, upgradable to 15 MW

✅ 108 m blades, 222 m rotor diameter

✅ Powers about 18,000 European homes annually

Siemens Gamesa Renewable Energy (SGRE) has released details of a 14-megawatt (MW) offshore wind turbine, as offshore green hydrogen production gains attention, in the latest example of how technology in the sector is increasing in scale.

With 108-meter-long blades and a rotor diameter of 222 meters, the dimensions of the SG 14-222 DD turbine are significant.

In a statement Tuesday, SGRE said that one turbine would be able to power roughly 18,000 average European households annually, while its capacity can also be boosted to 15 MW if needed. A prototype of the turbine is set to be ready by 2021, and it’s expected to be commercially available in 2024, as forecasts suggest a $1 trillion business this decade.

As technology has developed over the last few years, the size of wind turbines has increased, and renewables are set to shatter records globally.

Last December, for example, Dutch utility Eneco started to purchase power produced by the prototype of GE Renewable Energy’s Haliade-X 12 MW wind turbine. That turbine has a capacity of 12 MW, a height of 260 meters and a blade length of 107 meters.

The announcement of Siemens Gamesa’s new turbine plans comes against the backdrop of the coronavirus pandemic, which is impacting renewable energy companies around the world, even as wind power sees growth despite Covid-19 in many markets.

Earlier this month, the European company said Covid-19 had a “direct negative impact” of 56 million euros ($61 million) on its profitability between January and March, amid factory closures in Spain and supply chain disruptions. This, it added, was equivalent to 2.5% of revenues during the quarter.

The pandemic has, in some parts of the world, altered the sources used to power society. At the end of April, for instance, it was announced that a new record had been set for coal-free electricity generation in Great Britain, where UK offshore wind growth has accelerated, with a combination of factors — including coronavirus-related lockdown measures — playing a role.

On Tuesday, the CEO of another major wind turbine manufacturer, Danish firm Vestas, sought to emphasize the importance of renewable energy in the years and months ahead, and the lessons the U.S. can learn from the U.K. on wind deployment.

“I think we have actually, throughout this crisis, also shown to all society that renewables can be trusted,” Henrik Andersen said during an interview on CNBC’s Street Signs.

“But we both know ... that that transformation of energy sources is not going to happen overnight, it’s not going to happen from a quarter to a quarter, it’s going to happen by consistently planning year in, year out.”

UK Nuclear Free Electricity Incentive proposes community benefits near reactors, echoing France, supporting net zero goals, energy security, and streamlined planning, while addressing regulation and judicial review challenges for Sizewell C and future nuclear projects.

Key Points

A proposed policy to give free power to residents near reactors, supporting net zero and energy security.

✅ Free power for communities near nuclear plants

✅ Aligns with net zero and energy security goals

✅ Seeks streamlined planning and fewer approvals

UK Business Secretary Jacob Rees-Mogg has endorsed a French-style nuclear system that sees people living near nuclear power stations receive free electricity.

Speaking at an event organised by Policy Exchange think tank, Jacob Rees-Mogg said: “Nuclear power is just fundamental. There’s no way we can get to net zero emissions, or even have an intelligent electricity strategy and grid reform in the UK, without nuclear.”

Highlighting that this was his view and not a government policy announcement, he said: “We should copy the French. As I understand, if you live near a nuclear power station in France, you get free electricity and that’s great because then, I’ll have two in my garden if I get free electricity for my children as well.

“I think you want to recognise that things you do that are in the national interest, such as a state-owned generation company, must benefit those who make the sacrifice for the national interest.”

Earlier Mr Rees-Mogg stressed that he would like to see a simpler development consent process for new nuclear power plants to enable the next waves of reactors in the UK, amid concerns that Europe is losing nuclear power just when it really needs energy.

He said: “That’s a lot of regulation around that, as seen when nuclear plant plans collapsed in Wales and impacted the local economy. Did you know that Sizewell C will require 140 individual approvals from arms of the state, each one of which is potentially subject to judicial review.”

Quinone-mediated fuel cell uses a bio-inspired organic shuttle to carry electrons and protons to a nearby cobalt catalyst, improving hydrogen conversion, cutting platinum dependence, and raising efficiency while lowering costs for clean electricity.

Key Points

An affordable, bio-inspired fuel cell using an organic quinone shuttle and cobalt catalyst to move electrons efficiently

✅ Organic quinone shuttles electrons to a separate cobalt catalyst

✅ Reduces platinum use, lowering cost of hydrogen power

✅ Bio-inspired design aims to boost efficiency and durability

Fuel cells have long been viewed as a promising power source. But most fuel cells are too expensive, inefficient, or both. In a new approach, inspired by biology, a team has designed a fuel cell using cheaper materials and an organic compound that shuttles electrons and protons.

Fuel cells have long been viewed as a promising power source. These devices, invented in the 1830s, generate electricity directly from chemicals, such as hydrogen and oxygen, and produce only water vapor as emissions. But most fuel cells are too expensive, inefficient, or both.

In a new approach, inspired by biology and published today (Oct. 3, 2018) in the journal Joule, a University of Wisconsin-Madison team has designed a fuel cell using cheaper materials and an organic compound that shuttles electrons and protons.

In a traditional fuel cell, the electrons and protons from hydrogen are transported from one electrode to another, where they combine with oxygen to produce water. This process converts chemical energy into electricity. To generate a meaningful amount of charge in a short enough amount of time, a catalyst is needed to accelerate the reactions.

Right now, the best catalyst on the market is platinum -- but it comes with a high price tag, and while advances like low-cost heat-to-electric materials show promise, they address different conversion pathways. This makes fuel cells expensive and is one reason why there are only a few thousand vehicles running on hydrogen fuel currently on U.S. roads.

Shannon Stahl, the UW-Madison professor of chemistry who led the study in collaboration with Thatcher Root, a professor of chemical and biological engineering, says less expensive metals can be used as catalysts in current fuel cells, but only if used in large quantities. "The problem is, when you attach too much of a catalyst to an electrode, the material becomes less effective," he says, "leading to a loss of energy efficiency."

The team's solution was to pack a lower-cost metal, cobalt, into a reactor nearby, where the larger quantity of material doesn't interfere with its performance. The team then devised a strategy to shuttle electrons and protons back and forth from this reactor to the fuel cell.

The right vehicle for this transport proved to be an organic compound, called a quinone, that can carry two electrons and protons at a time. In the team's design, a quinone picks up these particles at the fuel cell electrode, transports them to the nearby reactor filled with an inexpensive cobalt catalyst, and then returns to the fuel cell to pick up more "passengers."

Many quinones degrade into a tar-like substance after only a few round trips. Stahl's lab, however, designed an ultra-stable quinone derivative. By modifying its structure, the team drastically slowed down the deterioration of the quinone. In fact, the compounds they assembled last up to 5,000 hours -- a more than 100-fold increase in lifetime compared to previous quinone structures.

"While it isn't the final solution, our concept introduces a new approach to address the problems in this field," says Stahl. He notes that the energy output of his new design produces about 20 percent of what is possible in hydrogen fuel cells currently on the market. On the other hand, the system is about 100 times more effective than biofuel cells that use related organic shuttles.

The next step for Stahl and his team is to bump up the performance of the quinone mediators, allowing them to shuttle electrons more effectively and produce more power. This advance would allow their design to match the performance of conventional fuel cells, but with a lower price tag.

"The ultimate goal for this project is to give industry carbon-free options for creating electricity, including thermoelectric materials that harvest waste heat," says Colin Anson, a postdoctoral researcher in the Stahl lab and publication co-author. "The objective is to find out what industry needs and create a fuel cell that fills that hole."

This step in the development of a cheaper alternative could eventually be a boon for companies like Amazon and Home Depot that already use hydrogen fuel cells to drive forklifts in their warehouses.

"In spite of major obstacles, the hydrogen economy, with efforts such as storing electricity in pipelines in Europe, seems to be growing," adds Stahl, "one step at a time."

Financial support for this project was provided by the Center for Molecular Electrocatalysis, an Energy Frontier Research Center funded by the U.S. Department of Energy, Office of Science, Office of Basic Energy Sciences, and by the Wisconsin Alumni Research Foundation (WARF) through the WARF Accelerator Program.

US Termination of Ukraine Energy Grid Support signals a policy shift: USAID halts aid for grid restoration amid Russia attacks, impacting energy security, infrastructure resilience, winter readiness, and negotiations leverage with Moscow and allies.

Key Points

A US policy reversal ending USAID support for Ukraine's grid, impacting energy security, resilience, and leverage.

✅ USAID halt reduces funds for grid restoration and winter prep

✅ Policy shift may weaken Kyiv's leverage in talks with Russia

✅ Ukraine seeks EU, IFIs, private capital for energy resilience

The U.S. government has recently decided to terminate its support for Ukraine's energy grid restoration, a critical initiative managed by the U.S. Agency for International Development (USAID). This decision, reported by NBC News, comes at a time when Ukraine is grappling with significant challenges to its energy infrastructure due to ongoing Russian attacks. The termination of support was reportedly finalized before Ukrainian President Volodymyr Zelensky's scheduled visit to Washington, marking a significant shift in U.S. policy and raising concerns about the broader implications for Ukraine's energy resilience and its negotiations with Russia.

The Critical Role of U.S. Support

Since Russia's invasion of Ukraine, the country’s energy infrastructure has been one of the primary targets of military strikes. Russia has launched numerous attacks on Ukraine's power generation facilities, substations, and power lines, causing power outages across multiple regions. These attacks have led to significant material losses, with damage reaching billions of dollars. As part of its commitment to Ukraine, the U.S. government, through USAID, had been instrumental in funding restoration efforts aimed at rebuilding and reinforcing Ukraine’s energy grid.

USAID's support was crucial in helping Ukraine withstand the damage inflicted by Russian missile strikes. This aid was not just about restoring basic services but also about fortifying the energy grid to ensure that Ukraine could continue functioning amidst the war and keep the lights on this winter as temperatures drop. The U.S. contribution to Ukraine's energy sector, alongside international support, helped reduce the immediate vulnerabilities faced by Ukraine's civilians and industries.

The Abrupt Change in U.S. Policy

The decision to cut support for energy grid restoration is seen as a sharp reversal in U.S. policy, particularly as the Biden administration has previously shown strong backing for Ukraine in the aftermath of the invasion. This shift in policy was reportedly made by the U.S. State Department, which directed USAID to halt its involvement in the energy sector.

According to NBC News, USAID officials expressed concern about the timing of this decision. One official noted that terminating support for Ukraine’s energy grid restoration would severely undermine the U.S. government's ability to negotiate on issues like ceasefires and peace talks with Russia. The official argued that such a move would signal to Russia that the U.S. is backing away from its long-term investments in Ukraine, potentially weakening Ukraine's position in the ongoing war.

The abrupt end to this support is also seen as a blow to the morale of Ukraine’s government and people. Ukraine had been heavily reliant on the U.S. for resources to repair its critical infrastructure, and the decision to cut this support without warning has created uncertainty about the future of such recovery efforts.

Ukraine’s Response and Search for Alternatives

In response to the termination of U.S. support, Ukrainian officials have been seeking alternative sources of funding to continue the restoration of their energy grid. Deputy Prime Minister Olha Stefanishyna reported that Ukraine has already reached preliminary agreements with other international partners to secure financial support for energy resilience, cyber defense, and recovery programs including new energy solutions for winter blackouts.

These efforts come at a time when Ukraine is working to rebuild its war-torn economy and safeguard critical sectors like energy and infrastructure. The termination of U.S. support for energy restoration projects underscores the growing pressure on Ukraine to diversify its sources of aid and not become overly dependent on any one nation. Ukrainian leaders are in ongoing talks with European governments, international financial institutions, and private investors to ensure that essential programs do not stall due to the lack of funding from the U.S., as energy cooperation grows and Ukraine helps Spain amid blackouts in solidarity.

Implications for Ukraine’s Energy Security

Ukraine's energy security remains a critical issue in the context of the ongoing conflict with Russia. The war has made the country’s energy infrastructure vulnerable to repeated attacks, and the restoration of this infrastructure is essential for ensuring that Ukraine can keep the lights on and recover in the long term. The U.S. has been one of the largest contributors to Ukraine's energy security efforts, and its withdrawal could force Ukraine to look for other partners who may not have the same level of financial or technological resources.

This development also raises questions about the future of U.S. involvement in Ukraine's recovery efforts more broadly. As the war continues and winter looms over the battlefront for frontline communities, the need for reliable and sustained support from international partners will only increase. If the U.S. significantly scales back its aid, Ukraine may face even greater challenges in maintaining its energy infrastructure and achieving long-term recovery.

Moving Forward

The termination of U.S. support for Ukraine’s energy grid restoration serves as a reminder of the complexities involved in international aid and geopolitics during wartime. As Ukraine faces the ongoing realities of the war, it must adapt to a shifting international landscape where traditional allies may not always be reliable sources of support. Ukraine’s leadership will need to be strategic in its search for alternative sources of aid, while also focusing on strengthening its energy grid, managing electricity reserves to stabilize supply, and reducing its vulnerabilities to Russian attacks.

While the end of U.S. support for Ukraine's energy restoration is a significant setback, it also underscores the urgent need for Ukraine to diversify its international partnerships. The future of Ukraine’s energy resilience may depend on how effectively it can navigate these changing dynamics while maintaining the support of the international community in the fight against Russian aggression.

BC Hydro Air Conditioning Efficiency Tips help cut energy bills as HVAC use rises. Avoid inefficient portable AC units, set thermostats near 25 C, use fans and window shading, and turn systems off when unoccupied.

Key Points

BC Hydro's guidelines to lower summer power bills by optimizing A/C settings, fans, shading, and usage habits at home.

✅ Set thermostats to 25 C; switch off A/C when away

✅ Prefer fans and window shading; close doors/windows in heat

✅ Avoid multiple portable A/C units; choose efficient HVAC

BC Hydro is scolding British Columbians for their ineffective, wasteful and costly use of home air conditioners.

In what the electric utility calls “not-so-savvy” behaviour, it says many people are over-spending on air conditioning units that are poorly installed or used incorrectly.

"The majority of British Columbians will spend more time at home this summer because of the COVID-19 pandemic," BC Hydro says in a news release about an August survey of customers.

"With A/C use on the rise, there is evidence British Columbians are not cooling down efficiently, leading to higher summer electricity bills, as extreme heat boosts U.S. bills too this summer."

BC Hydro estimates some customers are shelling out $200 more on their summer energy bills than they need to during a record-breaking 2021 demand year for electricity.

The pandemic is compounding the demand for cool, comfortable air at home. Roughly two in five British Columbians between the ages of 25 and 50 are working from home five days a week.

However, it’s not just COVID-19 that is putting a strain on energy consumption and monthly bills, with drought affecting generation as well today.

About 90 per cent of people who use an air conditioner set it to a temperature below the recommended 25 Celsius, according to BC Hydro.

In fact, one in three people have set their A/C to the determinedly unseasonable temperature of 19 C.

Another 30 per cent are using more than one portable air conditioning unit, which the utility says is considered the most inefficient model on the market, and questions remain about crypto mining electricity use in B.C. today.

The use of air conditioners is steadily increasing in B.C. and has more than tripled since 2001, according to BC Hydro, with all-time high demand also reported in B.C. during recent heat waves. The demand for climate control is particularly high among condo-dwellers since apartments tend to trap heat and stay warmer.

This may explain why one in 10 residents of the Lower Mainland has three portable air conditioning units, and elsewhere Calgary's frigid February surge according to Enmax.

In addition, 30 per cent of people keep the air conditioning on for the sake of their pets while no one is home.

BC Hydro makes these recommendations to save energy and money on monthly bills while still keeping homes cooled during summer’s hottest days, and it also offers a winter payment plan to help manage costs:

Cool homes to 25 C in summer months when home; air conditioning should be turned off when homes are unoccupied.
In place of air conditioning, running a fan for nine hours a day over the summer costs $7.
Shading windows with drapes and blinds can help insulate a home by keeping out 65 per cent of the heat.
If the temperature outside a home is warmer than inside, keep doors and windows closed to keep cooler air inside.
Use a microwave, crockpot or toaster oven to avoid the extra heat produced by larger appliances, such as an oven, when cooking. Hang clothes to dry instead of using a dryer on hot days.
