Great River Energy HQ awarded Platinum LEED certification

Proton Conducting Fuel Cells enable reversible hydrogen energy storage, coupling electrolyzers and fuel cells with ceramic catalysts and proton-conducting membranes to convert wind and solar electricity into fuel and back to reliable grid power.

Key Points

Proton conducting fuel cells store renewable power as hydrogen and generate electricity using reversible catalysts.

✅ Reversible electrolysis and fuel-cell operation in one device

✅ Ceramic air electrodes hit up to 98% splitting efficiency

✅ Scalable path to low-cost grid energy storage with hydrogen

If we want a shot at transitioning to renewable energy, we’ll need one crucial thing: technologies that can convert electricity from wind, sun, and even electricity from raindrops into a chemical fuel for storage and vice versa. Commercial devices that do this exist, but most are costly and perform only half of the equation. Now, researchers have created lab-scale gadgets that do both jobs. If larger versions work as well, they would help make it possible—or at least more affordable—to run the world on renewables.

The market for such technologies has grown along with renewables: In 2007, solar and wind provided just 0.8% of all power in the United States; in 2017, that number was 8%, according to the U.S. Energy Information Administration. But the demand for electricity often doesn’t match the supply from solar and wind, a key reason why the U.S. grid isn't 100% renewable today. In sunny California, for example, solar panels regularly produce more power than needed in the middle of the day, but none at night, after most workers and students return home.

Some utilities are beginning to install massive banks of cheaper solar batteries in hopes of storing excess energy and evening out the balance sheet. But batteries are costly and store only enough energy to back up the grid for a few hours at most. Another option is to store the energy by converting it into hydrogen fuel. Devices called electrolyzers do this by using electricity—ideally from solar and wind power—to split water into oxygen and hydrogen gas, a carbon-free fuel. A second set of devices called fuel cells can then convert that hydrogen back to electricity to power cars, trucks, and buses, or to feed it to the grid.

But commercial electrolyzers and fuel cells use different catalysts to speed up the two reactions, meaning a single device can’t do both jobs. To get around this, researchers have been experimenting with a newer type of fuel cell, called a proton conducting fuel cell (PCFC), which can make fuel or convert it back into electricity using just one set of catalysts.

PCFCs consist of two electrodes separated by a membrane that allows protons across. At the first electrode, known as the air electrode, steam and electricity are fed into a ceramic catalyst, which splits the steam’s water molecules into positively charged hydrogen ions (protons), electrons, and oxygen molecules. The electrons travel through an external wire to the second electrode—the fuel electrode—where they meet up with the protons that crossed through the membrane. There, a nickel-based catalyst stitches them together to make hydrogen gas (H2). In previous PCFCs, the nickel catalysts performed well, but the ceramic catalysts were inefficient, using less than 70% of the electricity to split the water molecules. Much of the energy was lost as heat.

Now, two research teams have made key strides in improving this efficiency, and a new fuel cell concept brings biological design ideas into the mix. They both focused on making improvements to the air electrode, because the nickel-based fuel electrode did a good enough job. In January, researchers led by chemist Sossina Haile at Northwestern University in Evanston, Illinois, reported in Energy & Environmental Science that they came up with a fuel electrode made from a ceramic alloy containing six elements that harnessed 76% of its electricity to split water molecules. And in today’s issue of Nature Energy, Ryan O’Hayre, a chemist at the Colorado School of Mines in Golden, reports that his team has done one better. Their ceramic alloy electrode, made up of five elements, harnesses as much as 98% of the energy it’s fed to split water.

When both teams run their setups in reverse, the fuel electrode splits H2 molecules into protons and electrons. The electrons travel through an external wire to the air electrode—providing electricity to power devices. When they reach the electrode, they combine with oxygen from the air and protons that crossed back over the membrane to produce water.

The O’Hayre group’s latest work is “impressive,” Haile says. “The electricity you are putting in is making H2 and not heating up your system. They did a really good job with that.” Still, she cautions, both her new device and the one from the O’Hayre lab are small laboratory demonstrations. For the technology to have a societal impact, researchers will need to scale up the button-size devices, a process that typically reduces performance. If engineers can make that happen, the cost of storing renewable energy could drop precipitously, thereby moving us closer to cheap abundant electricity at scale, helping utilities do away with their dependence on fossil fuels.

New England oil-fired generation surges as ISO New England manages a cold snap, dual-fuel switching, and a natural gas price spike, highlighting winter reliability challenges, LNG and pipeline limits, and rising CO2 emissions.

Key Points

Reliance on oil-burning power plants during winter demand spikes when natural gas is costly or constrained.

✅ Driven by dual-fuel switching amid high natural gas prices

✅ ISO-NE winter reliability rules encourage oil stockpiles

✅ Raises CO2 emissions despite coal retirements and renewables growth

New England is relying on oil-fired generators for the most electricity since 2018 as a frigid blast boosts demand for power and natural gas prices soar across markets. 

Oil generators were producing more than 4,200 megawatts early Thursday, accounting for about a quarter of the grid’s power supply, according to ISO New England. That was the most since Jan. 6, 2018, when oil plants produced as much as 6.4 gigawatts, or 32% of the grid’s output, said Wood Mackenzie analyst Margaret Cashman.  

Oil is typically used only when demand spikes, because of higher costs and emissions concerns. Consumption has been consistently high over the past three weeks as some generators switch from gas, which has surged in price in recent months. New England generators are producing power from oil at an average rate of almost 1.8 gigawatts so far this month, the highest for January in at least five years. 

Oil’s share declined to 16% Friday morning ahead of an expected snowstorm, which was “a surprise,” Cashman said. 

“It makes me wonder if some of those generators are aiming to reserve their fuel for this weekend,” she said.

During the recent cold snap, more than a tenth of the electricity generated in New England has been produced by power plants that haven’t happened for at least 15 years.

Burning oil for electricity was standard practice throughout the region for decades. It was once our most common fuel for power and as recently as 2000, fully 19% of the six-state region’s electricity came from burning oil, according to ISO-New England, more than any other source except nuclear power at the time.

Since then, however, natural gas has gotten so cheap that most oil-fired plants have been shut or converted to burn gas, to the point that just 1% of New England’s electricity came from oil in 2018, whereas about half our power came from natural gas generation regionally during that period. This is good because natural gas produces less pollution, both particulates and greenhouse gasses, although exactly how much less is a matter of debate.

But as you probably know, there’s a problem: Natural gas is also used for heating, which gets first dibs. Prolonged cold snaps require so much gas to keep us warm, a challenge echoed in Ontario’s electricity system as supply tightens, that there might not be enough for power plants – at least, not at prices they’re willing to pay.

After we came close to rolling brownouts during the polar vortex in the 2017-18 winter because gas-fired power plants cut back so much, ISO-NE, which has oversight of the power grid, established “winter reliability” rules. The most important change was to pay power plants to become dual-fuel, meaning they can switch quickly between natural gas and oil, and to stockpile oil for winter cold snaps.

We’re seeing that practice in action right now, as many dual-fuel plants have switched away from gas to oil, just as was intended.

That switch is part of the reason EPA says the region’s carbon emissions have gone up in the pandemic, from 22 million tons of CO2 in 2019 to 24 million tons in 2021. That reverses a long trend caused partly by closing of coal plants and partly by growing solar and offshore wind capacity: New England power generation produced 36 million tons of CO2 a decade ago.

So if we admit that a return to oil burning is bad, and it is, what can we do in future winters? There are many possibilities, including tapping more clean imports such as Canadian hydropower to diversify supply.

The most obvious solution is to import more natural gas, especially from fracked fields in New York state and Pennsylvania. But efforts to build pipelines to do that have been shot down a couple of times and seem unlikely to go forward and importing more gas via ocean tanker in the form of liquefied natural gas (LNG) is also an option, but hits limits in terms of port facilities.

Aside from NIMBY concerns, the problem with building pipelines or ports to import more gas is that pipelines and ports are very expensive. Once they’re built they create a financial incentive to keep using natural gas for decades to justify the expense, similar to moves such as Ontario’s new gas plants that lock in generation. That makes it much harder for New England to decarbonize and potentially leaves ratepayers on the hook for a boatload of stranded costs.

Manitoba NDP Geothermal Conversion Program offers full-cost heat pump installation for 5,000 homes, lowering electricity bills, funding contractor training and rebates, and cutting greenhouse gas emissions via geothermal energy administered by Efficiency Manitoba.

Key Points

A plan funding 5,000 home heat pump conversions to cut electricity bills, reduce emissions, and expand installer capacity.

✅ Covers equipment and installation for 5,000 homes

✅ Cuts electricity bills up to 50% vs electric heat

✅ Administered by Efficiency Manitoba; trains contractors

An NDP government would cover the entire cost for 5,000 families to switch their homes to geothermal energy, New Democrats have promised.

If elected on Oct. 3, the NDP will pay for the equipment and installation of new geothermal systems at 5,000 homes, St. James candidate Adrien Sala announced outside a St. Boniface home that previously made the switch. 

The homes that switch to geothermal energy could save as much as 50 per cent on their electricity bills, Sala said.

"It will save you money, it will grow our economy and it will reduce greenhouse gas emissions. And I think we can safely call that a win, win, win," Sala said.

Geothermal energy is derived from heat that is generated within the Earth.

The NDP said each conversion to geothermal heating and cooling would cost an estimated $26,000, and comes as new turbine investments advance in Manitoba, and it would take four years to complete all 5,000 conversions.

The program would be administered through Efficiency Manitoba, the Crown corporation responsible for conserving energy, as Manitoba Hydro's new president navigates changes at the utility. The NDP estimates it will cost $32.5 million annually over the four years, at a time of red ink at Manitoba Hydro as new power generation needs loom. Some of that money would support the training of more contractors who could install geothermal systems.

Subsidies get low pickup: NDP
Sala wouldn't say Wednesday which homeowners or types of homes would be eligible.

He said the NDP's plan would be a first in Canada, even as Ontario's energy plan seeks to address growing demand elsewhere.

"What we've seen elsewhere is where other jurisdictions have used a strict subsidy model, where they try to reduce the cost of geothermal, and while Ontario reviews a halt to natural gas generation to cut emissions, approaches differ across provinces. We really haven't seen a lot of uptake in those other jurisdictions," Sala said.

"This is an attempt at dealing with one of those key barriers for homeowners."

Efficiency Manitoba runs a subsidy program for geothermal energy through ground source heat pumps, supporting using more electricity for heat across the province, valued at up to $2.50 per square foot. It is estimated a 1,600 sq. ft. home switching from an electric furnace to geothermal will receive a rebate of around $4,000 and save around $900 annually on their electricity bills, the Crown corporation said.anitoba homeProgressive Conservative spokesperson Shannon Martin questioned how NDP Leader Wab Kinew can afford his party's numerous election promises.

"He will have no choice but to raise taxes, and history shows the NDP will raise them all," said Martin, the McPhillips MLA who isn't seeking re-election.

Wednesday's announcement was the first for the NDP in which Kinew wasn't present. The party has criticized the Progressive Conservatives for leader Heather Stefanson showing up for only a few announcements a week.

Sala said Kinew was busy preparing for the debate later in the day.

"This stuff is near and dear to Wab's heart, and frankly, I think he's probably hurting that he's not here with us right now."

Ontario Off-Peak Electricity Rate offers 8.2 cents per kWh for 24 hours, supporting Time-of-Use and Tiered Regulated Price Plan customers, including residential, small business, and farms, under Ontario Energy Board guidelines during temporary relief.

Key Points

A temporary 8.2 cents per kWh all-day price for RPP customers, covering TOU and Tiered users across Ontario.

✅ Applies 24 hours daily at 8.2 cents per kWh for 21 days

✅ Covers residential, small business, and farm RPP customers

✅ Valid for TOU and Tiered plans set by the Ontario Energy Board

 The Ontario government has announced electricity relief with electricity prices set at the off-peak price of 8.2 cents per kilowatt-hour, 24 hours per day for 21 days starting January 18, 2022, until the end of day February 7, 2022, for all Regulated Price Plan customers. The off-peak rate will apply automatically to residential, small businesses and farms who pay Time-of-Use or Tiered prices set by the Ontario Energy Board.

This rate relief includes extended off-peak rates to support small businesses, as well as workers and families spending more time at home while the province is in Modified Step Two of the Roadmap to Reopen.

As part of our mandate, we set the rates that your utility charges for the electricity you use in your home or small business. These rates appear on the Electricity line of your bill, and we administer protections such as disconnection moratoriums for residential customers. We also set the Delivery rates that cover the cost to deliver electricity to most residential and small business customers.

Types of electricity rates

For residential and small business customers that buy electricity from their utility, there are two different types of rates (also called prices here), and Ontario also provides stable electricity pricing for larger users. The Ontario Energy Board sets both once a year on November 1:

Time-of-Use (TOU)

With TOU prices, the price depends on when you use electricity, including options like ultra-low overnight pricing that encourage off-peak use.

There are three TOU price periods:

• Off-peak, when demand for electricity is lowest and new offerings like the Ultra-Low Overnight plan can encourage shifting usage. Ontario households use most of their electricity – nearly two thirds of it – during off-peak hours.
• Mid-peak, when demand for electricity is moderate. These periods are during the daytime, but not the busiest times of day, and utilities like BC Hydro are exploring similar TOU structures as well.
• On-peak, when demand for electricity is generally higher. These are the busier times of day – generally when people are cooking, starting up their computers and running heaters or air conditioners.

Bangladesh Rooppur Nuclear Power Plant advances nuclear energy with IAEA support and ROSATOM construction, boosting energy security, baseload capacity, and grid reliability; 2400 MW units aid development, regulatory compliance, and newcomer infrastructure milestones.

Key Points

A 2400 MW nuclear project in Rooppur, built with IAEA guidance and ROSATOM, to boost Bangladesh's reliable power.

✅ Two units totaling 2400 MW for stable baseload supply

✅ IAEA Milestones and INIR reviews guide safe deployment

✅ ROSATOM builds; national regulator strengthens oversight

The beginning of construction at Bangladesh’s first nuclear power reactor on 30 November 2017 marked a significant milestone in the decade-long process to bring the benefits of nuclear energy to the world’s eighth most populous country. The IAEA has been supporting Bangladesh on its way to becoming the third ‘newcomer’ country to nuclear power in 30 years, following the United Arab Emirates in 2012 and Belarus in 2013.

Bangladesh is in the process of implementing an ambitious, multifaceted development programme to become a middle-income country by 2021 and a developed country by 2041. Vastly increased electricity production, with the goal of connecting 2.7 million more homes to the grid by 2021, is a cornerstone of this push for development, and nuclear energy will play a key role in this area, said Mohammad Shawkat Akbar, Managing Director of Nuclear Power Plant Company Bangladesh Limited. Bangladesh is also working to diversify its energy supply to enhance energy security, reduce its dependence on imports and on its limited domestic resources, he added.

#google# In the region, India's nuclear program is taking steps to get back on track, underscoring broader momentum.

“Bangladesh is introducing nuclear energy as a safe, environmentally friendly and economically viable source of electricity generation,” said Akbar.  The plant in Rooppur, 160 kilometres north-west of Dhaka, will consist of two units, with a combined power capacity of 2400 MW(e). It is being built by a subsidiary of Russia’s State Atomic Energy Corporation ROSATOM. The first unit is scheduled to come online in 2023 and the second in 2024, reflecting progress similar to the UK's latest nuclear power station developments.  “This project will enhance the development of the social, economic, scientific and technological potential of the country,” Akbar said.

The country’s goal of increased electricity production via nuclear energy will soon be a reality, Akbar said. “For 60 years, Bangladesh has had a dream of building its own nuclear power plant. The Rooppur Nuclear Power Plant will provide not only a stable baseload of electricity, but it will enhance our knowledge and allow us to increase our economic efficiency.

Milestones for nuclear

Bangladesh is among around 30 countries that are considering, planning or starting the introduction of nuclear power, with milestones at nuclear projects worldwide offering context for this progress. The IAEA assists them in developing their programmes through the Milestones Approach — a methodology that provides guidance on working towards the establishment of nuclear power in a newcomer country, including the associated infrastructure. It focuses on pointing out gaps, if any, in countries’ progress towards the introduction of nuclear power.

The IAEA has been supporting Bangladesh in developing its nuclear power infrastructure, including in establishing a regulatory framework and developing a radioactive waste-management system. This support has been delivered under the IAEA technical cooperation programme and is partially funded through the Peaceful Uses Initiative.

Nuclear infrastructure is multifaceted, containing governmental, legal, regulatory and managerial components, in addition to the physical infrastructure. The Milestones Approach consists of three phases, with a milestone to be reached at the end of each.

The first phase involves considerations before a decision is taken to start a nuclear power programme and concludes with the official commitment to the programme. The second phase entails preparatory work for the contracting and construction of a nuclear power plant, as seen in Bulgaria's nuclear project planning, ending with the commencement of bids or contract negotiations for the construction. The final phase includes activities to implement the nuclear power plant, such as the final investment decision, contracting and construction. The duration of these phases varies by country, but they typically take between 10 and 15 years.

“The IAEA Milestones Approach is a guiding document and the Integrated Work Plan (IWP) is the important means of bringing all of the stakeholders in Bangladesh together to ensure the fulfilment of all safety, security, and safeguards requirements of the Rooppur NPP project,” said Akbar. “This IWP enabled Bangladesh to develop a holistic approach to implementing IAEA guidance as well as cooperating with national stakeholders and other bilateral partners towards the development of a national nuclear power programme.”

When completed, the two units of the Rooppur Nuclear Power Plant will have a combined power capacity of 2400 MW(e). (Photo: Arkady Sukhonin/Rosatom)

INIR Mission

The Integrated Nuclear Infrastructure Review (INIR) is a holistic peer review to assist Member States in assessing the status of their national infrastructure for introducing nuclear power. The IAEA completed its first INIR mission to Bangladesh in November 2011, making recommendations on how to develop a plan to establish the nuclear infrastructure. Nearly five years later, in May 2016, a follow-up mission was conducted, which noted the progress made — Bangladesh had established a nuclear regulatory body, had chosen a site for the power plant and had completed site characterization and environmental impact assessment.

“The IAEA and other bodies, including those from experienced countries, can and do provide support, but the responsibility for safety and security will lie with the Government,” said Dohee Hahn, Director of the IAEA’s Division of Nuclear Power, at the ceremony for the pouring of the first nuclear safety-related concrete at Rooppur on 30 November 2017. “The IAEA stands ready to continue supporting Bangladesh in developing a safe, secure, peaceful and sustainable nuclear power programme.”

Nova Scotia Power Rate Increase Settlement faces UARB scrutiny as regulators weigh electricity rates, fuel costs, storm rider provisions, Bill 212 limits, and Muskrat Falls impacts on ratepayers and affordability for residential and industrial customers.

Key Points

A deal proposing 13.8% electricity hikes for 2023-2024, before the UARB, covering fuel costs, a storm rider, and Bill 212.

✅ UARB review may set different rates than the settlement

✅ Fuel cost prepayment and hedging incentives questioned

✅ Storm rider shifts climate risk onto ratepayers

Nova Scotia Premier Tim Houston is calling on provincial regulators to reject a settlement agreement between Nova Scotia Power and customer groups that would see electricity rates rise by nearly 14% electricity rate hike over the next two years.

"It is our shared responsibility to protect ratepayers and I can't state strongly enough how concerned I am that the agreement before you does not do that," Houston wrote in a letter to the Nova Scotia Utility and Review Board late Monday.

Houston urged the three-member panel to "set the agreement aside and reach its own conclusion on the aforementioned application."

"I do not believe, based on what I know, that the proposed agreement is in the best interest of ratepayers," he said.

The letter does not spell out what his Progressive Conservative government would do if the board accepts the settlement reached last week between Nova Scotia Power and lawyers representing residential, small business and large industrial customer classes.

Other groups also endorsed the deal, although Nova Scotia Power's biggest customer — Port Hawkesbury Paper — did not sign on.

'We're protecting the ratepayers'
Natural Resources Minister Tory Rushton said the province was not part of the negotiations leading up to the settlement.

"As a government or department we had no intel on those conversations that were taking place," he said Tuesday. "So, we saw the information the same as the public did late last week, and right now we're protecting the ratepayers of Nova Scotia, even though the province cannot order Nova Scotia Power to lower rates under current law. We want to make sure that that voice is still heard at the UARB level."

Rushton said he didn't want to presuppose what the UARB will say.

"But I think the premier's been very loud and clear and I believe I have been, too. The ratepayers are at the top of our mind. We have different tools at our [disposal] and we'll certainly do what we can and need to [do] to protect those ratepayers."

The settlement agreement
If approved by regulators, rates would rise by 6.9 per cent in 2023 and 6.9 per cent in 2024 — almost the same amount on the table when hearings before the review board ended in September.

The Houston government later intervened with legislation, known as Bill 212, that capped rates to cover non-fuel costs by 1.8 per cent. It did not cap rates to cover fuel costs or energy efficiency programs.

In a statement announcing the agreement, Nova Scotia Power president Peter Gregg claimed the settlement adhered "to the direction provided by the provincial government through Bill 212."

Consumer advocate Bill Mahody, representing residential customers, told CBC News the proposed 13.8 per cent increase was "a reasonable rate increase given the revenue requirement that was testified to at the hearing."

Settlement 'remarkably' similar to NSP application
The premier disagrees, noting that the settlement and rate application that triggered the rate cap are "remarkably consistent."

He objects to the increased amount of fuel costs rolled into rates next year before the annual true up of actual fuel costs, which are automatically passed on to ratepayers.

"If Nova Scotia Power is effectively paid in advance, what motive do they have to hedge and mitigate the adjustment eventually required," Houston asked in his letter.

He also objected to the inclusion of a storm rider in rates to cover extreme weather, which he said pushed the risk of climate change on to ratepayers.

Premier second-guesses Muskrat Falls approval
Houston also second-guessed the board for approving Nova Scotia Power's participation in the Muskrat Falls hydro project in Labrador.

"The fact that Nova Scotians have paid over $500 million for this project with minimal benefit, and no one has been held accountable, is wrong," he said. "It was this board of the day that approved the contracts and entered the final project into rates."

Ratepayers are committed to paying $1.7 billion for the Maritime Link to bring the green source of electricity into the province, while rate mitigation talks in Newfoundland lack public details for their customers.

Although the Maritime Link was built on time and on budget by an affiliated company, only a fraction of Muskrat Falls hydro has been delivered because of ongoing problems in Newfoundland, including an 18% electricity rate hike deemed unacceptable by the province's consumer advocate.

"I find it remarkable that those contracts did not include different risk sharing mechanisms; they should have had provisions for issues in oversight of project management. Nevertheless, it was approved, and is causing significant harm to ratepayers in the form of increased rates."

Houston notes that because of non-delivery from Muskrat Falls, Nova Scotia Power has been forced to buy much more expensive coal to burn to generate electricity.

Opposition reaction
Opposition parties in Nova Scotia reacted to Houston's letter.

NDP Leader Claudia Chender dismissed it as bluster.

"It exposes his Bill 212 as not really helping Nova Scotians in the way that he said it would," she said. "Nothing in the settlement agreement contravenes that bill. But it seems that he's upset that he's been found out. And so here we are with another intervention in an independent regulatory body."

Liberal Leader Zach Churchill said the government should intervene to help ratepayers directly.

"We just think that it makes more sense to do that directly by supporting ratepayers through heating assistance, lump-sum electricity credits, rebate programs and expanding the eligibility for that or to provide funding directly to ratepayers instead of intervening in the energy market in this way," he said.

The premier's office said that no one was available when asked about an interview on Tuesday.

"The letter speaks for itself," the office responded.

Nova Scotia Power issued a statement Tuesday. It did not directly address Houston's claims.

"The settlement agreement is now with the NS Utility and Review Board," the utility said.

"The UARB process is designed to ensure customers are represented with strong advocates and independent oversight. The UARB will determine whether the settlement results in just and reasonable rates and is in the public interest."
