Power plant needed to meet energy demand

Air-gen Protein Nanowire Generator delivers clean energy by harvesting ambient humidity via Geobacter-derived conductive nanowires, generating continuous hydrovoltaic electricity through moisture gradients, electrodes, and proton diffusion for sustainable, low-waste power in diverse climates.

Key Points

A device using Geobacter protein nanowires to harvest humidity, producing continuous DC power via proton diffusion.

✅ 7 micrometer film between electrodes adsorbs water vapor.

✅ Output: ~0.5 V, 17 uA/cm2; stack units to scale power.

✅ Geobacter optimized via engineered E. coli for mass nanowires.

They found it buried in the muddy shores of the Potomac River more than three decades ago: a strange "sediment organism" that could do things nobody had ever seen before in bacteria.

This unusual microbe, belonging to the Geobacter genus, was first noted for its ability to produce magnetite in the absence of oxygen, but with time scientists found it could make other things too, like bacterial nanowires that conduct electricity.

For years, researchers have been trying to figure out ways to usefully exploit that natural gift, and they might have just hit pay-dirt with a device they're calling the Air-gen. According to the team, their device can create electricity out of… well, almost nothing, similar to power from falling snow reported elsewhere.

"We are literally making electricity out of thin air," says electrical engineer Jun Yao from the University of Massachusetts Amherst. "The Air-gen generates clean energy 24/7."

The claim may sound like an overstatement, but a new study by Yao and his team describes how the air-powered generator can indeed create electricity with nothing but the presence of air around it. It's all thanks to the electrically conductive protein nanowires produced by Geobacter (G. sulfurreducens, in this instance).

The Air-gen consists of a thin film of the protein nanowires measuring just 7 micrometres thick, positioned between two electrodes, referencing advances in near light-speed conduction in materials science, but also exposed to the air.

Because of that exposure, the nanowire film is able to adsorb water vapour that exists in the atmosphere, offering a contrast to legacy hydropower models, enabling the device to generate a continuous electrical current conducted between the two electrodes.

The team says the charge is likely created by a moisture gradient that creates a diffusion of protons in the nanowire material.

"This charge diffusion is expected to induce a counterbalancing electrical field or potential analogous to the resting membrane potential in biological systems," the authors explain in their study.

"A maintained moisture gradient, which is fundamentally different to anything seen in previous systems, explains the continuous voltage output from our nanowire device."

The discovery was made almost by accident, when Yao noticed devices he was experimenting with were conducting electricity seemingly all by themselves.

"I saw that when the nanowires were contacted with electrodes in a specific way the devices generated a current," Yao says.

"I found that exposure to atmospheric humidity was essential and that protein nanowires adsorbed water, producing a voltage gradient across the device."

Previous research has demonstrated hydrovoltaic power generation using other kinds of nanomaterials – such as graphene-based systems now under study – but those attempts have largely produced only short bursts of electricity, lasting perhaps only seconds.

By contrast, the Air-gen produces a sustained voltage of around 0.5 volts, with a current density of about 17 microamperes per square centimetre, and complementary fuel cell solutions can help keep batteries energized, with a current density of about 17 microamperes per square centimetre. That's not much energy, but the team says that connecting multiple devices could generate enough power to charge small devices like smartphones and other personal electronics – concepts akin to virtual power plants that aggregate distributed resources – all with no waste, and using nothing but ambient humidity (even in regions as dry as the Sahara Desert).

"The ultimate goal is to make large-scale systems," Yao says, explaining that future efforts could use the technology to power homes via nanowire incorporated into wall paint, supported by energy storage for microgrids to balance supply and demand.

"Once we get to an industrial scale for wire production, I fully expect that we can make large systems that will make a major contribution to sustainable energy production."

If there is a hold-up to realising this seemingly incredible potential, it's the limited amount of nanowire G. sulfurreducens produces.

Related research by one of the team – microbiologist Derek Lovley, who first identified Geobacter microbes back in the 1980s – could have a fix for that: genetically engineering other bugs, like E. coli, to perform the same trick in massive supplies.

"We turned E. coli into a protein nanowire factory," Lovley says.

"With this new scalable process, protein nanowire supply will no longer be a bottleneck to developing these applications."

Ontario Nuclear Refurbishment Economic Impact powers growth as Bruce Power's MCR and OPG's Darlington unit 2 refurbishment drive jobs, supply-chain spending, medical isotopes, clean baseload power, and lower GHG emissions across Ontario and Canada.

Key Points

It is the measured gains from Bruce Power's MCR and OPG's Darlington refurbishment in jobs, taxes, and clean energy.

✅ CAD7.6B-10.6B impact in Ontario; CAD8.1B-11.6B nationwide.

✅ Supports 60% nuclear supply, jobs, and medical isotopes.

✅ MCR and Darlington cut GHGs, drive innovation and supply chains.

The 13-year Major Component Replacement (MCR) project being undertaken as part of Bruce Power's life-extension programme, which officially began with a reactor taken offline earlier this year, will inject billions of dollars into Ontario's economy, a new report has found. Meanwhile, the major project to refurbish Darlington unit 2 remains on track for completion in 2020, Ontario Power Generation (OPG) has announced.

The Ontario Chamber of Commerce (OCC) said its report, Major Component Replacement Project Economic Impact Analysis, outlines an impartial assessment of the MCR programme and related manufacturing contracts across the supply chain. The report was commissioned by Bruce Power.

"Our analysis shows that Bruce Power's MCR project is a fundamental contributor to the Ontario economy. More broadly, the life-extension of the Bruce Power facility will provide quality jobs for Ontarians, produce a stable supply of medical isotopes for the world's healthcare system, and deliver economic benefit through direct and indirect spending," OCC President and CEO Rocco Rossi said."As Ontario's energy demand grows, nuclear truly is the best option to meet those demands with reduced GHG [greenhouse gas] emissions. The Bruce Power MCR Project will not only drive economic growth in the region, it will position Ontario as a global leader in nuclear innovation and expertise."

According to the OCC's economic analysis, the MCR's economic impact on Ontario is estimated to be between CAD7.6 billion (USD5.6 billion) and CAD10.6 billion. Nationally, its economic impact is estimated to be between CAD8.1 billion and CAD11.6 billion. It estimates that the federal government will receive CAD144 million in excise tax and CAD1.2 billion in income tax, while the provincial government will receive CAD300 million and CAD437 million. Ontario’s municipal governments are estimated to receive a collective CAD192 million in tax.

The nuclear industry currently provides 60% of Ontario’s daily energy supply needs, with Pickering life extension plans bolstering system reliability, and is made up of over 200 companies and more than 60,000 jobs across a diversity of sectors such as operations, manufacturing, skilled trades, healthcare, and research and innovation, the report notes.

Greg Rickford, Ontario's minister of Energy, Northern Development and Mines, and minister of Indigenous Affairs, said continued use of the Bruce generating station which recently set an operating record would create jobs and advance Ontario’s nuclear industrial sector. "It is great to see projects like the MCR that help make Ontario the best place to invest, do business and find a job," he said.

The MCR is part of Bruce Power's overall life-extension programme, which started in January 2016. Bruce 6 will be the first of the six Candu units to undergo an MCR which will take 46 months to complete and give the unit a further 30-35 years of operational life. The total cost of refurbishing Bruce units 3-8 is estimated at about CAD8 billion, in addition to CAD5 billion on other activities under the life-extension programme, which is scheduled for completion by 2053.

Darlington milestones

OPG's long-term refurbishment programme at Darlington, alongside SMR plans for the site announced by the province, began with unit 2 in 2016 after years of detailed planning and preparation. Reassembly of the reactor, which was disassembled last year, is scheduled for completion this spring, and the unit 2 refurbishment project remains on track for completion in early 2020. At the same time, final preparations are under way for the start of the refurbishment of unit 3.

"We've entered a critical phase on the project," Senior Vice President of Nuclear Refurbishment Mike Allen said. "OPG and our project partners continue to work as an integrated team to meet our commitments on Unit 2 and our other three reactors at Darlington Nuclear Generating Station."

A 350-tonne generator stator manufactured by GE in Poland is currently in transit to Canada, where it will be installed in Darlington 3's turbine hall as the province also breaks ground on its first SMR this year.

The 10-year Darlington refurbishment is due to be completed in 2026, while the province plans to refurbish Pickering B to extend output beyond that date.

Labor National Electricity Market Reform aims to rebalance NEM rules, support a fair-dinkum clean energy target, enable renewable zones, bolster storage and grid reliability, empower households, and unlock CEFC investment via the Finkel review.

Key Points

Labor's plan to overhaul NEM rules for households, clean energy targets, renewable zones, storage, and CEFC investment.

✅ Revises NEM rules to curb big generators' market power

✅ Backs a clean energy target informed by the Finkel review

✅ Expands renewable zones, storage, and CEFC finance

Australia's Labor leader Bill Shorten has called for significant changes to the rules governing the national electricity market, saying they are biased in favour of big energy generators, leaving households worse off even with measures like a WA electricity bill credit in place.

He said the national electricity market (NEM) rules are designed to help the big companies recoup the money they spent on purchasing government assets, a dynamic echoed in debates like a Calgary market overhaul dispute unfolding in Canada, rather than encourage households to generate their own power, and they need to change faster to adapt to consumer needs.

His comments hint at a possible overhaul of the NEM’s governance structure under a future Labor government, because the current rule-making process is too cumbersome and slow, with suggested rules changes taking years to be introduced.

Daniel Andrews defends claims that civil liberties a 'luxury' in fight against terrorism

Labor had promoted a similar idea in the lead-up to the 2016 election, with its call for an electricity modernization review, but now the Finkel review has been released it would be used to guide such a review.

In a speech to the Australian Financial Review’s National Energy Summit in Sydney on Monday, Shorten recommitted Labor to negotiating a “fair-dinkum” clean energy target with the Turnbull government, amid modelling that a strong clean energy target can lower electricity prices, saying “it’s time to put away the weapons of the climate change wars” and work together to find a way forward.

He said the media and business can all share the blame for Australia’s lost decade of energy policy development, with examples abroad showing how leadership steers change, such as in Alberta where Kenney's influence on power policy has been pronounced, but “we need to stop spoiling for a fight and start seeking a solution”.

“The scare campaigns and hyper-partisanship that got Australia into this mess, will not get us out of it,” he will say.

“That’s why, a bit over four months ago, before the chief scientist released his report, I wrote to the prime minister offering an olive branch.

“I said Labor was prepared to move from our preferred position of an emissions intensity scheme and negotiate a fair-dinkum clean energy target.

“That offer was greeted with some cynicism in the media. But let me be crystal clear – I made that offer in good faith, and that offer still stands.”

Shorten said Australia needs to resolve the current “gas crisis” and do more to drive investment in renewable energy that delivers more reliable electricity, a priority underscored by the IEA's warning that falling global energy investment risks shortages, and if Labor wins the next election it will organise Australia into a series of renewable energy zones – as recommended by the chief scientist, Alan Finkel – that identify wind, solar, pumped hydro and geothermal resources, and connect them to the existing network.

“These zones would be based on both existing generation and storage in the area – and the potential for future development,” he said.

Australia's politics only barrier to clean energy system, report finds

“Identifying these zones – from eastern Queensland, north-east New South Wales, west Victoria, the Eyre Peninsula in South Australia and the entire state of Tasmania – will also plant a flag for investors – signalling future sites for job-creating projects.”

Shorten also said Labor will free up the Clean Energy Finance Corporation to invest in more generation and more storage.

“Under Labor, the return benchmark for the CEFC was set at the weighted average of the Australian government bond rate.

“Under this government, it was initially increased to the weighted average plus 4% to 5% and is now set at the average plus 3% to 4%.

“Setting the return benchmark too high defeats the driving purpose of the CEFC and it holds back the crucial investment Australia needs – right now – in new generation and storage.

“This is why a Labor government would restore the original benchmark return of the Clean Energy Finance Corporation, to invest in more generation, more storage and more jobs.”

California Storm Outages and Landslides strain utilities, trigger flooding, road closures, and debris flows, causing widespread power cuts and infrastructure damage as emergency response teams race to restore service, clear slides, and support evacuations.

Key Points

California Storm Outages and Landslides are storm-driven power cuts and slope failures disrupting roads and utilities.

✅ Tens of thousands face prolonged power outages across regions

✅ Landslides block highways, damage property, hinder access

✅ Crews restore grids, clear debris, support shelters and evacuees

California is grappling with a dual crisis of power outages and landslides following a severe storm that has swept across the state. The latest reports indicate widespread disruptions affecting thousands of residents and significant infrastructure damage. This storm is not only a test of California's emergency response capabilities but also a stark reminder of the increasing vulnerability of the state to extreme weather events, and of the U.S. electric grid in the face of climate stressors.

Storm’s Impact on California

The recent storm, which hit California with unprecedented intensity, has unleashed torrential rain, strong winds, and widespread flooding. These severe weather conditions have overwhelmed the state’s infrastructure, leading to significant power outages that are affecting numerous communities. According to local utilities, tens of thousands of homes and businesses are currently without electricity. The outages have been exacerbated by the combination of heavy rain and gusty winds, which have downed power lines and damaged electrical equipment.

In addition to the power disruptions, the storm has triggered a series of landslides across various regions. The combination of saturated soil and intense rainfall has caused several hillside slopes to give way, leading to road closures and property damage. Emergency services are working around the clock to address the aftermath of these landslides, but access to affected areas remains challenging due to blocked roads and ongoing hazardous conditions.

Emergency Response and Challenges

California’s emergency response teams are on high alert as they coordinate efforts to manage the fallout from the storm. Utility companies are deploying repair crews to restore power as quickly as possible, but the extensive damage to infrastructure means that some areas may be without electricity for several days. The state’s Department of Transportation is also engaged in clearing debris from landslides and repairing damaged roads to ensure that emergency services can reach affected communities.

The response efforts are complicated by the scale of the storm’s impact. With many areas experiencing both power outages and landslides, the logistical challenges are immense. Emergency shelters have been set up to provide temporary refuge for those displaced by the storm, but the capacity is limited, and there are concerns about overcrowding and resource shortages.

Community and Environmental Implications

The storm’s impact on local communities has been profound. Residents are facing not only the immediate challenges of power outages and unsafe road conditions but also longer-term concerns about recovery and rebuilding. Many individuals have been forced to evacuate their homes, and local businesses are struggling to cope with the disruption.

Environmental implications are also significant. The landslides and flooding have caused considerable damage to natural habitats and have raised concerns about water contamination and soil erosion. The impact on the environment could have longer-term consequences for the state’s ecosystems and water supply.

Climate Change and Extreme Weather

This storm underscores a growing concern about the increasing frequency and intensity of extreme weather events linked to climate change. California has been experiencing a rise in severe weather patterns, including intense storms, prolonged droughts, and extreme heat waves that strain the grid. These changes are putting additional strain on the state’s infrastructure and emergency response systems.

Experts have pointed out that while individual storms cannot be directly attributed to climate change, the overall trend towards more extreme weather is consistent with scientific predictions. As such, there is a pressing need for California to invest in infrastructure improvements and resilience measures, and to consider accelerating its carbon-free electricity mandate to better withstand future events.

Looking Ahead

As California deals with the immediate aftermath of this storm, attention will turn to recovery and rebuilding efforts. The state will need to address the damage caused by power outages and landslides while also preparing for future challenges posed by climate change.

In the coming days, the focus will be on restoring power, clearing debris, and providing support to affected communities. Long-term efforts will likely involve reassessing infrastructure vulnerabilities, improving emergency response protocols, and investing in climate resilience measures across the grid.

EU Energy Price Crisis drives soaring electricity bills as natural gas sets pay-as-clear power prices; leaders debate price caps, common gas purchasing, market reform, renewables, and ETS changes amid Ukraine war supply shocks.

Key Points

A surge in gas-driven power costs linked to pay-as-clear pricing, supply shocks, and policy rifts across the EU market.

✅ Gas sets marginal power price via pay-as-clear mechanism

✅ Spain pushes decoupling and temporary price caps

✅ EU weighs joint gas buying, efficiency, more renewables

Nothing grabs politicians' attention faster than angry voters, and they've had plenty to be furious about as natural gas and electricity bills have soared to stomach-churning levels in recent months, as this UK natural gas analysis illustrates across markets.

That's led to a scramble to figure out ways to get those costs down, with emergency price-limiting measures under discussion — but that's turning out to be very difficult, so the likeliest result is that EU leaders meeting later this week won't come up with any solutions.

“There is no single easy answer to tackle the high electricity prices given the diversity of situations among Member States. Some options are only suitable for specific national contexts,” the European Commission said on Wednesday. “They all carry costs and drawbacks.” 

The initial problem was a surge in gas demand in Asia last year coupled with lower-than-normal Russian gas deliveries that left European gas storage at unusually low levels. Now the war in Ukraine is making matters even worse, as pressure grows for the bloc to rapidly cut its imports of Russian oil, coal and natural gas — although some national leaders reject the economic costs that would entail.

"We will end this dependence as quickly as we can, but to do that from one day to the next would mean plunging our country and all of Europe into a recession," German Chancellor Olaf Scholz warned on Wednesday.

The problem for the bloc is that its liberalized electricity market is tightly tied to the price of natural gas; power prices are set by the final input needed to balance demand — called pay-as-clear — which in most cases is set by natural gas. That's led to countries with large amounts of cheaper renewable or nuclear energy seeing sharp spikes in power prices thanks to the cost of that final bit of gas-fired electricity.

A Spanish-led coalition that includes Portugal, Belgium and Italy wants deep reforms to the EU price model, fueling a broader electricity market revamp debate in Brussels.

Others, such as the Netherlands and Germany, strongly oppose such an approach, echoing how nine countries oppose reforms at the EU level, and want to focus on cushioning the effects of the high prices on consumers and businesses, while letting the market operate. 

A third group, largely in Central Europe, wants to use the price spike to revamp or scrap the bloc's Emissions Trading System and to rethink its Fit for 55 climate legislation.

The European Commission has been holding the middle ground — arguing that the current market model makes sense, but encouraging countries to boost the amount of renewable electricity, in a wake-up call to ditch fossil fuels for Europe, to cut energy use and increase efficiency.

In draft conclusions of this week's European Council summit, seen by POLITICO, EU leaders, amid a France-Germany tussle over reform, call for things like a common approach to buying gas, aimed at preventing countries from competing against each other. But there's no big movement on electricity prices.

“It does not seem realistic to expect a result on the energy discussion at this European Council,” one diplomat said, stressing that the governments will need to see more analysis before committing to any more steps.

Looking for action
Spain wanted a much more robust response. Madrid has been arguing since last summer for “decoupling” gas from the electricity market; together with Portugal, it also mulled limiting the wholesale price of electricity to €180 per megawatt-hour — a proposal that Spain abandoned under fire from industry and consumer groups. 

Now Madrid is pushing to get a specific permission in the summit's final conclusions that would allow countries to voluntarily apply certain short-term solutions such as gas price cap strategies, according to a draft with track changes seen by POLITICO.

The issue with a cap is if gas prices are higher than the cap, Spain might not be able to buy any gas.
