BC Hydro still in dark about cause of blackout

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.

HVDC-WISE Project accelerates HVDC technology integration across the European transmission system, delivering a planning toolkit to boost grid reliability, resilience, and interconnectors for renewables and offshore wind amid climate, cyber, and physical threats.

Key Points

EU-funded project delivering tools to integrate HVDC into Europe's grid, improving reliability, resilience, and security.

✅ EU Horizon Europe-backed consortium of 14 partners

✅ Toolkit to assess extreme events and grid operability

✅ Supports interconnectors, offshore wind, and renewables

A partnership of 14 leading European energy industry companies, research organizations and universities has launched a new project to identify opportunities to increase integration of HVDC technology into the European transmission system, echoing calls to invest in smarter electricity infrastructure from abroad.

The HVDC-WISE project, in which the University of Strathclyde is the UK’s only academic partner, is supported by the European Union’s Horizon Europe programme.

The project’s goal is to develop a toolkit for grid developers to evaluate the grid’s performance under extreme conditions and to plan systems, leveraging a digital grid approach that supports coordination to realise the full range of potential benefits from deep integration of HVDC technology into the European transmission system.

The project is focused on enhancing electric grid reliability and resilience while navigating the energy transition. Building and maintaining network infrastructure to move power across Europe is an urgent and complex task, and reducing losses with superconducting cables can play a role, particularly with the continuing growth of wind and solar generation. At the same time, threats to the integrity of the power system are on the rise from multiple sources, including climate, cyber, and physical hazards.

Mutual support

At a time of increasing worries about energy security and as Europe’s electricity systems decarbonise, connections between them to provide mutual support and routes to market for energy from renewables, a dynamic also highlighted in discussions of the western Canadian electricity grid in North America, become ever more important.

In modern power systems, this means making use of High Voltage Direct Current (HVDC) technology.

The earliest forms of technology have been around since the 1960s, but the impact of increasing reliance on HVDC and its ability to enhance a power system’s operability and resilience are not yet fully understood.

Professor Keith Bell, Scottish Power Professor of Future Power Systems at the University of Strathclyde, said:

As an island, HVDC is the only practical way for us to build connections to other countries’ electricity systems. We’re also making use of it within our system, with one existing and more planned Scotland-England subsea link projects connecting one part of Britain to another.

“These links allow us to maximise our use of wind energy. New links to other countries will also help us when it’s not windy and, together with assets like the 2GW substation now in service, to recover from any major disturbances that might occur.

“The system is always vulnerable to weather and things like lightning strikes or short circuits caused by high winds. As dependency on electricity increases, insights from electricity prediction specialists can inform planning as we enhance the resilience of the system.”

Dr Agusti Egea-Alvarez, Senior Lecturer at Strathclyde, said: “HVDC systems are becoming the backbone of the British and European electric power network, either interconnecting countries, or connecting offshore wind farms.

“The tools, procedures and guides that will be developed during HVDC-WISE will define the security, resilience and reliability standards of the electric network for the upcoming decades in Europe.”

Other project participants include Scottish Hydro Electric Transmission, the Supergrid Institute, the Electric Power Research Institute (EPRI) Europe, Tennet TSO, Universidad Pontificia Comillas, TU Delft, Tractebel Impact and the University of Cyprus.

Climate change

Eamonn Lannoye, Managing Director of EPRI Europe, said: “The European electricity grid is remarkably reliable by any standard. But as the climate changes and the grid becomes exposed to more extreme conditions, energy interdependence between regions intensifies and threats from external actors emerge. The new grid needs to be robust to those challenges.”

Juan Carlos Gonzalez, a senior researcher with the SuperGrid Institute which leads the project said: “The HVDC-WISE project is intended to provide planners with the tools and know-how to understand how grid development options perform in the context of changing threats and to ensure reliability.”

HVDC-WISE is supported by the European Union’s Horizon Europe programme under agreement 101075424 and by the UK Research and Innovation Horizon Europe Guarantee scheme.

U.S. Data Center Power Demand is straining electric utilities and grid reliability as AI, cloud computing, and streaming surge, driving transmission and generation upgrades, demand response, and renewable energy sourcing amid rising electricity costs.

Key Points

The rising electricity load from U.S. data centers, affecting utilities, grid capacity, and energy prices.

✅ AI, cloud, and streaming spur hyperscale compute loads

✅ Grid upgrades: transmission, generation, and substations

✅ Demand response, efficiency, and renewables mitigate strain

U.S. electric utilities are facing a significant new challenge as the explosive growth of data centers puts unprecedented strain on power grids across the nation. According to a new report from Reuters, data centers' power demands are expected to increase dramatically over the next few years, raising concerns about grid reliability and potential increases in electricity costs for businesses and consumers.

What's Driving the Data Center Surge?

The explosion in data centers is being fueled by several factors, with grid edge trends offering early context for these shifts:

• Cloud Computing: The rise of cloud computing services, where businesses and individuals store and process data on remote servers, significantly increases demand for data centers.
• Artificial Intelligence (AI): Data-hungry AI applications and machine learning algorithms are driving a massive need for computing power, accelerating the growth of data centers.
• Streaming and Video Content: The growth of streaming platforms and high-definition video content requires vast amounts of data storage and processing, further boosting demand for data centers.

Challenges for Utilities

Data centers are notorious energy hogs. Their need for a constant, reliable supply of electricity places  heavy demand on the grid, making integrating AI data centers a complex planning challenge, often in regions where power infrastructure wasn't designed for such large loads. Utilities must invest significantly in transmission and generation capacity upgrades to meet the demand while ensuring grid stability.

Some experts warn that the growth of data centers could lead to brownouts or outages, as a U.S. blackout study underscores ongoing risks, especially during peak demand periods in areas where the grid is already strained. Increased electricity demand could also lead to price hikes, with utilities potentially passing the additional costs onto consumers and businesses.

Sustainable Solutions Needed

Utility companies, governments, and the data center industry are scrambling to find sustainable solutions, including using AI to manage demand initiatives across utilities, to mitigate these challenges:

• Energy Efficiency: Data center operators are investing in new cooling and energy management solutions to improve energy efficiency. Some are even exploring renewable energy sources like onsite solar and wind power.
• Strategic Placement: Authorities are encouraging the development of data centers in areas with abundant renewable energy and access to existing grid infrastructure. This minimizes the need for expensive new transmission lines.
• Demand Flexibility: Utility companies are experimenting with programs as part of a move toward a digital grid architecture to incentivize data centers to reduce their power consumption during peak demand periods, which could help mitigate power strain.

The Future of the Grid

The rapid growth of data centers exemplifies the significant challenges facing the aging U.S. electrical grid, with a recent grid report card highlighting dangerous vulnerabilities. It highlights the need for a modernized power infrastructure, capable of accommodating increasing demand spurred by new technologies while addressing climate change impacts that threaten reliability and affordability.  The question for utilities, as well as data center operators, is how to balance the increasing need for computing power with the imperative of a sustainable and reliable energy future.

Alberta Hydropower Potential highlights renewable energy, dams, reservoirs, grid flexibility, contrasting wind and solar growth with limited investment, regulatory hurdles, river basin resources, and decarbonization pathways across Athabasca, Peace, and Slave River systems.

Key Points

It is the technical capacity for new hydro in Alberta's river basins to support a more reliable, lower carbon grid.

✅ 42,000 GWh per year developable hydro identified in studies.

✅ Major potential in Athabasca, Peace, and Slave River basins.

✅ Barriers include high capital costs, market design, water rights.

When you think about renewable energy sources on the Prairies, your mind may go to the wind farms in southern Alberta, or even the Travers Solar Project, southeast of Calgary.

Most of the conversation around renewable energy in the province is dominated by advancements in solar and wind power, amid Alberta's renewable energy surge that continues to attract attention. 

But what about Canada's main source of electricity — hydro power?

More than half of Canada's electricity is generated from hydro sources, with 632.2 terawatt-hours produced as of 2019. That makes it the fourth largest installed capacity of hydropower in the world. 

But in Alberta, it's a different story. 

Currently, hydro power contributes between three and five per cent of Alberta's energy mix, while fossil fuels make up about 89 per cent.

According to Canada's Energy Future report from the Canada Energy Regulator, by 2050 it will make up two per cent of the province's electricity generation shares.

So why is it that a province so rich in mountains and rivers has so little hydro power?

Hydro's history in Alberta
Hydro power didn't always make up such a small sliver of Alberta's electricity generation. Hydro installations began in the early 20th century as the province's population exploded. 

Grant Berg looks after engineering for hydro for TransAlta, Alberta's largest producer of hydro power with 17 facilities across the province.

"Our first plant was Horseshoe, which started in 1911 that we formed as Calgary Power," he said. 

"It was really in response to the City of Calgary growing and having some power needs."

Berg said in 1913, TransAlta's second installation, the Kananaskis Plant, started as Calgary continued to grow.

Some bigger installations were built in the 1920s, including Ghost reservoir, but by mid-century population growth increased.

"Quite a large build out really, I think in response to the growth in Alberta following the war. So through the 1950s really quite a large build out of hydro from there."

By the 1950s, around half of the province's installed capacity was hydro power.

"Definitely Calgary power was all hydro until the 1950s," said Berg. 

Hydro potential in the province 
Despite the current low numbers in hydroelectricity, Alberta does have potential. 

According to a 2010 study, there is approximately 42,000 gigawatt-hours per year of remaining developable hydroelectric energy potential at identified sites. 

An average home in Alberta uses around 7,200 kilowatt-hours of electricity per year, meaning that the hydro potential could power 5.8 million homes each year. 

"This volume of energy could be sufficient to serve a significant amount of Alberta's load and therefore play a meaningful role in the decarbonization of the province's electric system," the Alberta Electric System Operator said in its 2022 Pathways to Net-Zero Emissions report.

Much of that potential lies in northern Alberta, in the Athabasca, Peace and Slave River basins.

The AESO report says that despite the large resource potential, Alberta's energy-only market framework has attracted limited investment in hydroelectric generation. 

Hydro power was once a big deal in Alberta, but investment in the industry has been in decline since the 1950s. Climate change reporter Christy Climenhaga explains why.
So why does Alberta leave out such a large resource potential on the path to net zero?

The government of Alberta responded to that question in a statement. 

"Hydro facilities, particularly large scale ones involving dams, are associated with high costs and logistical demands," said the Ministry of Affordability and Utilities. 

"Downstream water rights for other uses, such as irrigation, further complicate the development of hydro projects."

The ministry went on to say that wind and solar projects have increased far more rapidly because they can be developed at relatively lower cost and shorter timelines, and with fewer logistical demands.

"Sources from wind power and solar are increasingly more competitive," said Jean-Denis Charlebois, chief economist with the Canadian Energy Regulator. 

Hydro on the path to net zero
Hydro power is incredibly important to Canada's grid, and will remain so, despite growth in wind and solar power across the province.

Charlebois said that across Canada, the energy make-up will depend on the province. 

"Canadian provinces will generate electricity in very different ways from coast to coast. The major drivers are essentially geography," he said. 

Charlebois says that in British Columbia, Manitoba, Quebec and Newfoundland and Labrador, hydropower generation will continue to make up the majority of the grid.

"In Alberta and Saskatchewan, we see a fair bit of potential for wind and solar expansion in the region, which is not necessarily the case on Canada's coastlines," he said.

And although hydro is renewable, it does bring its adverse effects to the environment — land use changes, changes in flow patterns, fish populations and ecosystems, which will have to be continually monitored. 

"You want to be able to manage downstream effects; make sure that you're doing all the proper things for the environment," said Ryan Braden, director of mining and hydro at TransAlta.

Braden said hydro power still has a part to play in Alberta, even with its smaller contributions to the future grid. 

"It's one of those things that, you know, the wind doesn't blow or the sun doesn't shine, this is here. The way we manage it, we can really support that supply and demand," he said.

Miami Valley Windstorm Power Outages disrupted thousands as 60 mph gusts toppled trees, downed power lines, and damaged buildings. Utility crews and emergency services managed debris, while NWS alerts warned of extended restoration.

Key Points

Region-wide power losses from severe winds in the Miami Valley, causing damage, debris, and restoration.

✅ 60 mph gusts downed trees, snapped lines, blocked roads

✅ Crews from DP&L worked extended shifts to restore service

✅ NWS issued wind advisories; schools, businesses closed

On a recent day, powerful winds tore through the Miami Valley, causing significant disruption across the region. The storm, which was accompanied by gusts reaching dangerous speeds, led to windstorm power outages affecting thousands of homes and businesses. As trees fell and power lines were snapped, many residents found themselves without electricity for hours, and in some cases, even days.

The high winds, which were part of a larger weather system moving through the area, left a trail of destruction in their wake. In addition to power outages, there were reports of storm damage to buildings, vehicles, and other structures. The force of the wind uprooted trees, some of which fell on homes and vehicles, causing significant property damage. While the storm did not result in any fatalities, the destruction was widespread, with many communities experiencing debris-filled streets and blocked roads.

Utility companies in the Miami Valley, including Dayton Power & Light, quickly mobilized crews, similar to FPL's storm response in major events, to begin restoring power to the affected areas. However, the high winds presented a challenge for repair crews, as downed power lines and damaged equipment made restoration efforts more difficult. Many customers were left waiting for hours or even days for their power to be restored, and some neighborhoods were still experiencing outages several days after the storm had passed.

In response to the severe weather, local authorities issued warnings to residents, urging them to stay indoors and avoid unnecessary travel. Wind gusts of up to 60 miles per hour were reported, making driving hazardous, particularly on bridges and overpasses, similar to Quebec windstorm outages elsewhere. The National Weather Service also warned of the potential for further storm activity, advising people to remain vigilant as the system moved eastward.

The impact of the storm was felt not only in terms of power outages but also in the strain it placed on emergency services. With trees blocking roads and debris scattered across the area, first responders were required to work quickly and efficiently to clear paths and assist those in need. Many residents were left without heat, refrigeration, and in some cases, access to medical equipment that relied on electricity.

Local schools and businesses were also affected by the storm. Many schools had to cancel classes, either due to power outages or because roads were impassable. Businesses, particularly those in the retail and service sectors, faced disruptions in their operations as they struggled to stay open without power amid extended outages that lingered, or to address damage caused by fallen trees and debris.

In the aftermath of the storm, Miami Valley residents are working to clean up and assess the damage. Many homeowners are left dealing with the aftermath of tree removal, property repairs, and other challenges. Meanwhile, local governments are focusing on restoring infrastructure, as seen after Toronto's spring storm outages in recent years, and ensuring that the power grid is secured to prevent further outages.

While the winds have died down and conditions have improved, the storm’s impact will be felt for weeks to come, reflecting Florida's weeks-long restorations after severe storms. The region will continue to recover from the damage, but the event serves as a reminder of the power of nature and the resilience of communities in the face of adversity. For residents affected by the power outages, recovery will require patience as utility crews and local authorities work tirelessly to restore normalcy.

Looking ahead, experts are urging residents to prepare for the next storm season by ensuring that they have emergency kits, backup generators, and contingency plans in place. As climate change contributes to more extreme weather events, it is likely that storms of this magnitude will become more frequent. By taking steps to prepare in advance, communities across the Miami Valley can better handle whatever challenges come next.

Iceland Bitcoin Mining Energy Shortage highlights surging cryptocurrency and blockchain data center electricity demand, as hydroelectric and geothermal power strain to cool servers, stabilize grid, and meet rapid mining farm growth amid Arctic-friendly conditions.

Key Points

Crypto mining data centers in Iceland are outpacing renewable power, straining the grid and exceeding residential electricity demand.

✅ Hydroelectric and geothermal capacity nearing allocation limits

✅ Cooling-friendly climate draws energy-hungry mining farms

✅ Grid planning and regulation lag rapid data center growth

The value of bitcoin may have stumbled in recent months, but in Iceland it has known only one direction so far: upward. The stunning success of cryptocurrencies around the globe has had a more unexpected repercussion on the island of 340,000 people: It could soon result in an energy shortage in the middle of the Atlantic Ocean.

As Iceland has become one of the world's prime locations for energy-hungry cryptocurrency servers — something analysts describe as a 21st-century gold-rush equivalent — the industry’s electricity demands have skyrocketed, too. For the first time, they now exceed Icelanders’ own private energy consumption, and energy producers fear that they won’t be able to keep up with rising demand if Iceland continues to attract new companies bidding on the success of cryptocurrencies, a concern echoed by policy moves like Russia's proposed mining ban amid electricity deficits.

Companies have flooded Iceland with requests to open new data centers to “mine” cryptocurrencies in recent months, even as concerns mount that the country may have to slow down investments amid an increasingly stretched electricity generation capacity, a dynamic seen in BC Hydro's suspension of new crypto connections in Canada.

“There was a lot of talk about data centers in Iceland about five years ago, but it was a slow start,” Johann Snorri Sigurbergsson, a spokesman for Icelandic energy producer HS Orka, told The Washington Post. “But six months ago, interest suddenly began to spike. And over the last three months, we have received about one call per day from foreign companies interested in setting up projects here.”

“If all these projects are realized, we won’t have enough energy for it,” Sigurbergsson said.

Every cryptocurrency in the world relies on a “blockchain” platform, which is needed to trade with digital currencies. Tracking and verifying a transaction on such a platform is like solving a puzzle because networks are often decentralized, and there is no single authority in charge of monitoring payments. As a result, a transaction involves an immense number of mathematical calculations, which in turn occupy vast computer server capacity. And that requires a lot of electricity, as analyses of bitcoin's energy use indicate worldwide.

The bitcoin rush may have come as a surprise to locals in sleepy Icelandic towns that are suddenly bustling with cryptocurrency technicians, but there’s a simple explanation. “The economics of bitcoin mining mean that most miners need access to reliable and very cheap power on the order of 2 or 3 cents per kilowatt hour. As a result, a lot are located near sources of hydro power, where it’s cheap,” Sam Hartnett, an associate at the nonprofit energy research and consulting group Rocky Mountain Institute, told the Washington Post.

Located in the middle of the Atlantic Ocean and famous for its hot springs and mighty rivers, Iceland produces about 80 percent of its energy in hydroelectric power stations, compared with about 6 percent in the United States, and innovations such as underwater kites illustrate novel ways to harness marine energy. That and the cold climate make it a perfect location for new data-mining centers filled with servers in danger of overheating.

Those conditions have attracted scores of foreign companies to the remote location, including Germany's Genesis Mining, which moved to Iceland about three years ago. More have followed suit since then or are in the process of moving. 

While some analysts are already sensing a possible new revenue source for the country that is so far mostly known abroad as a tourist haven and low-budget airline hub, others are more concerned by a phenomenon that has so far mostly alarmed analysts because of its possible financial unsustainability, alongside issues such as clean energy's dirty secret that complicate the picture. Some predictions have concluded that cryptocurrency computer operations may account for “all of the world’s energy by 2020” or may already account for the equivalent of Denmark's energy needs. Those predictions are probably too alarmist, though. 

Most analysts agree that the real energy-consumption figure is likely smaller, and several experts recently told the Washington Post that bitcoin — currently the world's biggest cryptocurrency — used no more than 0.14 percent of the world’s generated electricity, as of last December. Even though global consumption may not be as significant as some have claimed, it still presents a worrisome drain for a tiny country such as Iceland, where consumption suddenly began to spike with almost no warning — and continues to grow fast.

Some networks are considering or have already pushed through changes to their protocols, designed to reduce energy use. But implementing such changes for the leading currency, bitcoin, won't be as easy because it is inherently decentralized. The companies that provide the vast amounts of computing power needed for these transactions earn a small share, comparable to a processing fee or a reward.

They are the source of the Icelandic bitcoin miners’ income — a revenue source that many Icelanders are still not quite sure what to make of, especially if the lights start flickering.
