When the wind blows power flows, but what if electricity could still flow when the air is still?
Storing energy has long been a dream of wind-energy producers hoping to supply a consistent source of green power to the electrical grid — without using expensive batteries.
A Nisku firm thinks it has the answer, a revolutionary concept that could change the face of energy distribution.
Lancaster Wind Systems says by turning wind energy into hydraulic power, inert nitrogen gas can be compressed in thousands of kilometres of unused pipelines across North America — creating a sort of giant pressure tank.
Wind turbines would add pressure to the network, and small electricity-creating turbines tied into the system would draw off that pressure, producing power in a closed-loop system right where the electricity is needed.
"You might have 200 generators in a major city, each in the 1.5-megawatt to four-megawatt range. And since the nitrogen is returned to the pipeline, there are no emissions," said Dave McConnell, president and CEO of Lancaster.
He thinks electricity transmission lines will one day be a memory, with the continent's energy moving around as pressurized gas. The project has attracted funding from the Sustainable Development Technology Canada fund, and also raised millions from private investors.
With 18 patents already filed and more on the way, Lancaster has a working one-megawatt wind turbine producing hydraulic power, and plans to open a pilot project this summer in which 42 minutes of energy will be stored in a short pipeline section. A major pipeline company is supplying the material.
A wind turbine today is basically blades turning a shaft in a generator unit that creates electricity, with all the heavy equipment at the top of a strong mast.
Lancaster has turned that around. Its unit acts more like a windmill, with a lighter mast supporting the blades and hydraulic tubing, and the heavy equipment on the ground.
Currently the research focus is on details of transferring the energy to storage.
"That is where we are at, the mechanism of transferring this energy into a vessel. We can't talk about it, except that when the fluid comes down it is under pressure," said Arnie Barr, a field supervisor.
McConnell points out there is no hydraulic fluid in the storage system; it is simply moved into a tank and then sent back up the mast to be recompressed by the power of the wind.
"There is a pressure exchanger to convert the energy in the (hydraulic) fluid into the storage medium (nitrogen gas)," he said.
And that is about the limit of what Lancaster will say.
"There is a lot of concern about intellectual property. People drive in here and we kick them out. We have never spoken of this system to the media before," McConnell said.
However, he will discuss the turbine system, which is now fully patented.
All wind-power units today must govern their turbine speed in an effort to produce the appropriate 60-hertz supply frequency required by the power grid.
But because Lancaster is capturing energy in hydraulics and not directly producing electricity, this is not an issue. It can take all the power of the wind at any time of the day or night, and create its electricity at a steady rate.
"We aren't trying to restrict ourselves by feathering our blades. We don't care if the wind goes up or down, we don't have to worry about fluctuations. We just take the energy and store it," said systems analyst Terry van Gemert.
After a lifetime in the offshore-oil business, McConnell said he returned to Canada with the idea of buying a couple of drilling rigs. But then he had a better idea.
"The oilpatch is all feathers and chickens (bad and good years). My forte is hydraulics, and I spent time in Europe in the 1990s, where they are very concerned about green energy."
McConnell said it shouldn't be a surprise that Lancaster staff are oil people, as are most of the backers.
"The reality is the change in public thinking. Just look at Texas," which has 20 times more wind power installed than Alberta, as well as most of the U.S. petroleum industry.
"They will be one of the biggest players in green energy."
ITER Nuclear Fusion advances tokamak magnetic confinement, heating deuterium-tritium plasma with superconducting magnets, targeting net energy gain, tritium breeding, and steam-turbine power, while complementing laser inertial confinement milestones for grid-scale electricity and 2025 startup goals.
Key Points
ITER Nuclear Fusion is a tokamak project confining D-T plasma with magnets to achieve net energy gain and clean power.
✅ Tokamak magnetic confinement with high-temp superconducting coils
✅ Deuterium-tritium fuel cycle with on-site tritium breeding
✅ Targets net energy gain and grid-scale, low-carbon electricity
It sounds like the stuff of dreams: a virtually limitless source of energy that doesn’t produce greenhouse gases or radioactive waste. That’s the promise of nuclear fusion, often described as the holy grail of clean energy by proponents, which for decades has been nothing more than a fantasy due to insurmountable technical challenges. But things are heating up in what has turned into a race to create what amounts to an artificial sun here on Earth, one that can provide power for our kettles, cars and light bulbs.
Today’s nuclear power plants create electricity through nuclear fission, in which atoms are split, with next-gen nuclear power exploring smaller, cheaper, safer designs that remain distinct from fusion. Nuclear fusion however, involves combining atomic nuclei to release energy. It’s the same reaction that’s taking place at the Sun’s core. But overcoming the natural repulsion between atomic nuclei and maintaining the right conditions for fusion to occur isn’t straightforward. And doing so in a way that produces more energy than the reaction consumes has been beyond the grasp of the finest minds in physics for decades.
But perhaps not for much longer. Some major technical challenges have been overcome in the past few years and governments around the world have been pouring money into fusion power research as part of a broader green industrial revolution under way in several regions. There are also over 20 private ventures in the UK, US, Europe, China and Australia vying to be the first to make fusion energy production a reality.
“People are saying, ‘If it really is the ultimate solution, let’s find out whether it works or not,’” says Dr Tim Luce, head of science and operation at the International Thermonuclear Experimental Reactor (ITER), being built in southeast France. ITER is the biggest throw of the fusion dice yet.
Its $22bn (£15.9bn) build cost is being met by the governments of two-thirds of the world’s population, including the EU, the US, China and Russia, at a time when Europe is losing nuclear power and needs energy, and when it’s fired up in 2025 it’ll be the world’s largest fusion reactor. If it works, ITER will transform fusion power from being the stuff of dreams into a viable energy source.
Constructing a nuclear fusion reactor ITER will be a tokamak reactor – thought to be the best hope for fusion power. Inside a tokamak, a gas, often a hydrogen isotope called deuterium, is subjected to intense heat and pressure, forcing electrons out of the atoms. This creates a plasma – a superheated, ionised gas – that has to be contained by intense magnetic fields.
The containment is vital, as no material on Earth could withstand the intense heat (100,000,000°C and above) that the plasma has to reach so that fusion can begin. It’s close to 10 times the heat at the Sun’s core, and temperatures like that are needed in a tokamak because the gravitational pressure within the Sun can’t be recreated.
When atomic nuclei do start to fuse, vast amounts of energy are released. While the experimental reactors currently in operation release that energy as heat, in a fusion reactor power plant, the heat would be used to produce steam that would drive turbines to generate electricity, even as some envision nuclear beyond electricity for industrial heat and fuels.
Tokamaks aren’t the only fusion reactors being tried. Another type of reactor uses lasers to heat and compress a hydrogen fuel to initiate fusion. In August 2021, one such device at the National Ignition Facility, at the Lawrence Livermore National Laboratory in California, generated 1.35 megajoules of energy. This record-breaking figure brings fusion power a step closer to net energy gain, but most hopes are still pinned on tokamak reactors rather than lasers.
In June 2021, China’s Experimental Advanced Superconducting Tokamak (EAST) reactor maintained a plasma for 101 seconds at 120,000,000°C. Before that, the record was 20 seconds. Ultimately, a fusion reactor would need to sustain the plasma indefinitely – or at least for eight-hour ‘pulses’ during periods of peak electricity demand.
A real game-changer for tokamaks has been the magnets used to produce the magnetic field. “We know how to make magnets that generate a very high magnetic field from copper or other kinds of metal, but you would pay a fortune for the electricity. It wouldn’t be a net energy gain from the plant,” says Luce.
One route for nuclear fusion is to use atoms of deuterium and tritium, both isotopes of hydrogen. They fuse under incredible heat and pressure, and the resulting products release energy as heat
The solution is to use high-temperature, superconducting magnets made from superconducting wire, or ‘tape’, that has no electrical resistance. These magnets can create intense magnetic fields and don’t lose energy as heat.
“High temperature superconductivity has been known about for 35 years. But the manufacturing capability to make tape in the lengths that would be required to make a reasonable fusion coil has just recently been developed,” says Luce. One of ITER’s magnets, the central solenoid, will produce a field of 13 tesla – 280,000 times Earth’s magnetic field.
The inner walls of ITER’s vacuum vessel, where the fusion will occur, will be lined with beryllium, a metal that won’t contaminate the plasma much if they touch. At the bottom is the divertor that will keep the temperature inside the reactor under control.
“The heat load on the divertor can be as large as in a rocket nozzle,” says Luce. “Rocket nozzles work because you can get into orbit within minutes and in space it’s really cold.” In a fusion reactor, a divertor would need to withstand this heat indefinitely and at ITER they’ll be testing one made out of tungsten.
Meanwhile, in the US, the National Spherical Torus Experiment – Upgrade (NSTX-U) fusion reactor will be fired up in the autumn of 2022, while efforts in advanced fission such as a mini-reactor design are also progressing. One of its priorities will be to see whether lining the reactor with lithium helps to keep the plasma stable.
Choosing a fuel Instead of just using deuterium as the fusion fuel, ITER will use deuterium mixed with tritium, another hydrogen isotope. The deuterium-tritium blend offers the best chance of getting significantly more power out than is put in. Proponents of fusion power say one reason the technology is safe is that the fuel needs to be constantly fed into the reactor to keep fusion happening, making a runaway reaction impossible.
Deuterium can be extracted from seawater, so there’s a virtually limitless supply of it. But only 20kg of tritium are thought to exist worldwide, so fusion power plants will have to produce it (ITER will develop technology to ‘breed’ tritium). While some radioactive waste will be produced in a fusion plant, it’ll have a lifetime of around 100 years, rather than the thousands of years from fission.
At the time of writing in September, researchers at the Joint European Torus (JET) fusion reactor in Oxfordshire were due to start their deuterium-tritium fusion reactions. “JET will help ITER prepare a choice of machine parameters to optimise the fusion power,” says Dr Joelle Mailloux, one of the scientific programme leaders at JET. These parameters will include finding the best combination of deuterium and tritium, and establishing how the current is increased in the magnets before fusion starts.
The groundwork laid down at JET should accelerate ITER’s efforts to accomplish net energy gain. ITER will produce ‘first plasma’ in December 2025 and be cranked up to full power over the following decade. Its plasma temperature will reach 150,000,000°C and its target is to produce 500 megawatts of fusion power for every 50 megawatts of input heating power.
“If ITER is successful, it’ll eliminate most, if not all, doubts about the science and liberate money for technology development,” says Luce. That technology development will be demonstration fusion power plants that actually produce electricity, where advanced reactors can build on decades of expertise. “ITER is opening the door and saying, yeah, this works – the science is there.”
BC Hydro COVID-19 Bill Relief provides payment deferrals, no-penalty payment plans, Crisis Fund grants up to $600, and utility bill assistance as customers face pandemic layoffs, social distancing, and increased home power usage.
Key Points
A BC Hydro program offering bill deferrals, no-penalty plans, and up to $600 Crisis Fund grants during COVID-19.
✅ Defer payments or set no-penalty payment plans
✅ Apply for up to $600 Customer Crisis Fund grants
✅ Measures to ensure reliable power and remote customer service
BC Hydro is implementing a program, including bill relief measures, to help people pay their bills if they’re affected by the novel coronavirus.
The Crown corporation says British Columbians are facing a variety of financial pressures related to the COVID-19 pandemic, as some workplaces close or reduce staffing levels and commercial power consumption plummets across the province.
BC Hydro said it also expects increased power usage as more people stay home amid health officials’ requests that people take social distancing measures, even as electricity demand is down 10% provincewide.
Under the new program, customers will be able to defer bill payments or arrange a payment plan with no penalty, though a recent report on deferred operating costs outlines long-term implications for the utility.
BC Hydro says some customers could also be eligible for grants of up to $600 under its Customer Crisis Fund, if facing power disconnection due to job loss, illness or loss of a family member, while in other jurisdictions power bills were cut for households during the pandemic.
The company says it has taken precautions to keep power running by isolating key facilities, including its control centre, and by increasing its cleaning schedule, a priority even as some utilities face burgeoning debt amid COVID-19.
It has also closed its walk-in customer service desks to reduce risk from face-to-face contact and suspended all non-essential business travel, public meetings and site tours, and warned businesses about BC Hydro impersonation scams during this period.
Los Angeles Power Station Fire prompts LADWP to shut a Northridge/Reseda substation, causing a San Fernando Valley outage amid a heatwave; high-voltage equipment and mineral oil burned as 94,000 customers lost power, elevator rescues reported.
Key Points
An LADWP substation fire in Northridge/Reseda caused a major outage; 94,000 customers affected as crews restore power.
✅ Fire started around 6:52 p.m.; fully extinguished by 9 p.m.
✅ High-voltage gear and mineral oil burned; no injuries reported.
✅ Outages hit Porter Ranch, Reseda, West Hills, Granada Hills.
About 94,000 customers were without electricity Saturday night after the Los Angeles Department of Water and Power shut down a power station in the northeast San Fernando Valley that caught fire, the agency said.
The fire at the station in the Northridge/Reseda area of Los Angeles started about 6:52 p.m. and involved equipment that carries high-voltage electricity and distributes it at lower voltages to customers in the surrounding area, the department said, even as other utilities sometimes deploy wildfire safety shut-offs to reduce risk during dangerous conditions.
The department shut off power to the station as a precautionary move, and it is restoring power now that the fire has been put out, similar to restoration after intentional shut-offs in other parts of California. Initially, 140,000 customers were without power. That number had been cut to 94,000 by 11 p.m.
The power outage comes as much of California baked in heat that broke records, and rolling blackout warnings were issued as the grid strained. A record that stood 131 years in Los Angeles was snapped when the temperature spiked at 98 degrees downtown.
People reported losing power in Porter Ranch, Winnetka, West Hills, Canoga Park, Woodland Hills, Granada Hills, North Hills, Reseda and Chatsworth, KABC TV reported, highlighting electricity inequality across communities.
Shortly after the blaze broke out, firefighters found a huge container of mineral oil that is used to cool electrical equipment on fire, Los Angeles Fire Department spokesman Brian Humphrey told the Los Angeles Times. The incident underscores infrastructure risks that in some regions have required a complete grid rebuild after severe storms.
Firefighters had the blaze under control by 8:30 p.m. and were able to put it out by 9 p.m., Humphrey said. "These were fierce flames, with smoke towering more than 300 feet into the sky," he told the newspaper.
No one was injured.
Firefighters rescued people who were stranded in elevators, Humphrey said.
Gulf Power renewable energy contract underscores a Florida PSC-approved power purchase from Bay County's municipal solid waste plant, delivering 13.65 MW at a fixed price, boosting fuel diversity, lowering landfill waste, and saving customers money.
Key Points
A fixed-price PPA for 13.65 MW from Bay County's waste-to-energy plant, approved by Florida PSC to cut costs.
✅ Fixed-price purchase; pay only for energy produced.
✅ 13.65 MW from Bay County waste-to-energy facility.
✅ Cuts landfill waste and natural gas dependency.
The Florida Public Service Commission (PSC) approved Tuesday a contract under which Gulf Power Company will purchase all the electricity generated by the Bay County Resource Recovery Facility, a municipal solid waste plant, similar to SaskPower-Manitoba Hydro deal structures seen elsewhere, over the next six years.
“Gulf’s renewable energy purchase promotes Florida’s fuel diversity, further reducing our dependency on natural gas,” PSC Chairperson Julie Brown said. “This renewable energy option also reduces landfill waste, saves customers money, and serves the public interest.”
The contract provides for Gulf to acquire the Panama City facility’s 13.65 megawatts of renewable generation for its customers beginning in July 2017. Gulf will pay a fixed price, aligned with approaches in Alberta's clean electricity RFP programs, and only pays for the energy produced. The contract is expected to save approximately $250,000 and provides security for customers, a contrast to overruns at the Kemper power plant project, because if the plant does not supply energy, Gulf does not have to provide payment.
This contract is the third renewable energy contract between Gulf and Bay County, at a time when the Southern California plant closures may be postponed, continuing agreements approved in 2008 and 2014. In making the decision, the PSC considered Gulf’s need for power and developments such as the Turkey Point license renewal process, as well as the contract’s cost-effectiveness, payment provisions, and performance guarantees, as required by rule.
Ontario Global Adjustment Supreme Court Appeal spotlights a constitutional challenge to Ontario's electricity charge, pitting National Steel Car against the IESO over regulatory charge vs tax, procurement policy, and renewable energy feed-in tariff contracts.
Key Points
An SCC leave bid on whether Ontario's global adjustment is a valid regulatory charge or an unconstitutional tax.
✅ Appeals Court revived case for full record review
✅ Dispute centers on regulatory charge vs tax classification
✅ FIT renewables contracts and procurement policies at issue
The Ontario government wants the Supreme Court of Canada to weigh in on a constitutional challenge being brought against a large provincial electricity charge, a case the province claims raises issues of national importance.
Ontario’s attorney general and its Independent Electricity System Operator applied for permission to appeal to the Supreme Court in January, according to the court’s website.
The province is trying to appeal a Court of Appeal decision reinstating the challenge from November that said a legal challenge by Hamilton, Ont.-based National Steel Car Ltd. should be sent back to a lower-court for a full hearing.
Court reinstates constitutional challenge to Ontario's hefty ‘global adjustment’ electricity charge National Steel Car appealing decision in legal challenge of Ontario electricity fee it calls an unconstitutional tax Doug Ford’s cancellation of green energy deals costs Ontario taxpayers $231 million National Steel Car launched its legal challenge in 2017, with the maker of steel rail cars claiming the province’s global adjustment electricity charge was a tax intended to fund certain post-financial-crisis policy goals. Since it is allegedly a tax, and one not imposed by the provincial legislature, the company’s argument is the global adjustment is unconstitutional, and also in breach of a provincial law requiring a referendum for new taxes.
The global adjustment mostly bridges the gap between the province’s hourly electricity price and the price guaranteed under contracts and regulated rates with power generators. It also helps cover the cost of building new electricity infrastructure and providing conservation programs, but the fee now makes up most of the commodity portion of a household power bill in the province.
Ontario argued the global adjustment is a valid regulatory charge, and moved to have National Steel Car’s challenge thrown out. An Ontario Superior Court judge agreed, and dismissed the challenge in 2018, saying it was “plain, obvious and beyond doubt” it could not succeed. However, an appeals court judge disagreed, writing in a decision last November that the “merits should not have been determined on a pleadings motion and without the development of a full record.”
In filings made to the Supreme Court, both the IESO and Ontario’s Ministry of the Attorney General argued their proposed appeals raise “issues of national and public importance,” such as whether incorporating environmental and social policy goals in procurement could turn attempts by a public body to recover costs into an unconstitutional tax.
Most applications for leave to appeal to the Supreme Court are dismissed, but the Ontario government claims the court’s guidance is required in this case, as it could lead to questions being raised about other fees or charges, such as money raised from fishing licences.
“A failure to dispose of this claim at the pleadings stage may well result in such uncertainty that public authorities across Canada decline to incorporate the kind of environmental and social policy goals objected to in this case into the decisions they make about how to spend funds raised from regulatory charges,” the filing from the attorney general states. “Alternatively, it may induce governments not to engage in cost recovery in connection with publicly supplied goods and services, which can otherwise be sound public policy.”
The government has so far had to pay National Steel Car $250,000 in legal costs “to avoid responding to the credible claim that the Global Adjustment is an unconstitutional tax,” said David Trafford of Morse Shannon LLP, one of National Steel Car’s lawyers.
“The application for leave to appeal is the next step in this effort to avoid having to respond to the case on the merits,” Trafford added in an email.

National Steel Car has particularly taken issue with the part of the global adjustment that funded contracts for renewable energy under a “feed-in tariff” program, or FIT, which the company called “the main culprit behind the dramatic price increases for electricity.”
The FIT program has been ended, but contracts awarded under it remain in place and form part of the global adjustment. Ontario’s auditor general estimated in 2015 that electricity consumers would pay $9.2 billion more for renewable energy under the government’s guaranteed-price program, a figure that later featured in a dispute between the auditor and the electricity regulator that drew political attention.
National Steel Car said its global adjustment costs grew from $207,260 in 2008 to almost $3.4 million in 2016, reflecting how high electricity rates have pressured manufacturers, to almost $3.4 million in 2016. For 2018, there was approximately $11.2 billion in global adjustment collected, according to the IESO’s reporting.
A spokesperson for the IESO said it “is not in a position to comment” because the case is still before the courts.
Electricity prices have been an ongoing problem for both Ontario consumers and politicians, which the previous Liberal government tried to address in 2017 by, among other things, refinancing global-adjustment costs through the Fair Hydro Plan and other measures.
Since National Steel Car filed its lawsuits, though, the Liberals lost power in the province and were succeeded in 2018 by Premier Doug Ford and the Progressive Conservatives, who made changes to the previous government’s power policies, including legislation to lower electricity rates introduced early in their mandate.
The province has also pursued interprovincial power arrangements, including building on an electricity deal with Quebec as part of its broader energy strategy.
“The present government of Ontario does not agree with the former government’s electricity procurement program, which ceased awarding new contracts in 2016,” Ontario’s attorney general said in a filing. “However, Ontario submits that (the lower-court judge) was correct in holding that it does not give rise to a claim susceptible to being remedied by the courts.”
EPA Power Plant Emissions Rule proposes strict greenhouse gas limits for coal and gas units, leveraging carbon capture (CCS) under the Clean Air Act to cut CO2 and accelerate decarbonization of the U.S. grid.
Key Points
A proposed EPA rule setting CO2 limits for coal and gas plants, using CCS to cut power-sector greenhouse gases.
✅ Applies to existing and new coal and large gas units
✅ Targets near-zero CO2 by 2038 via CCS or retirement
✅ Cites grid, health, and climate benefits; faces legal challenges
The Biden administration has proposed new limits on greenhouse gas emissions from coal- and gas-fired power plants, its most ambitious effort yet to roll back planet-warming pollution from the nation’s second-largest contributor to climate change.
A rule announced by the Environmental Protection Agency could force power plants to capture smokestack emissions using a technology that has long been promised but is not used widely in the United States, and arrives amid changes stemming from the NEPA rewrite that affect project reviews.
“This administration is committed to meeting the urgency of the climate crisis and taking the necessary actions required,″ said EPA Administrator Michael Regan.
The plan would not only “improve air quality nationwide, but it will bring substantial health benefits to communities all across the country, especially our front-line communities ... that have unjustly borne the burden of pollution for decades,” Regan said in a speech at the University of Maryland.
President Joe Biden, whose climate agenda includes a clean electricity standard as a key pillar, called the plan “a major step forward in the climate crisis and protecting public health.”
If finalized, the proposed regulation would mark the first time the federal government has restricted carbon dioxide emissions from existing power plants, following a Trump-era replacement of Obama’s power plant overhaul, which generate about 25% of U.S. greenhouse gas pollution, second only to the transportation sector. The rule also would apply to future electric plants and would avoid up to 617 million metric tons of carbon dioxide through 2042, equivalent to annual emissions of 137 million passenger vehicles, the EPA said.
Almost all coal plants — along with large, frequently used gas-fired plants — would have to cut or capture nearly all their carbon dioxide emissions by 2038, the EPA said, a timeline that echoed concerns raised during proposed electricity pricing changes in the prior administration. Plants that cannot meet the new standards would be forced to retire.
The plan is likely to be challenged by industry groups and Republican-leaning states, much like litigation over the Affordable Clean Energy rule unfolded in recent years. They have accused the Democratic administration of overreach on environmental regulations and warn of a pending reliability crisis for the electric grid. The power plant rule is one of at least a half-dozen EPA rules limiting power plant emissions and wastewater treatment rules.
“It’s truly an onslaught” of government regulation “designed to shut down the coal fleet prematurely,″ said Rich Nolan, president and CEO of the National Mining Association.
Regan denied that the power plant rule was aimed at shutting down the coal sector, but acknowledged — even after the end to the 'war on coal' rhetoric — “We will see some coal retirements.”
