A new breakthrough could allow sunshine to become one of the most important sources of clean renewable energy, it has been claimed.

Up to now solar power has been a "Cinderella" energy source because storing the sun's energy is so expensive and inefficient.

Now scientists believe they have overcome the problem using technology inspired by photosynthesis in plants.

The system allows small amounts of electricity from solar panels to split water into hydrogen and oxygen. A similar water-splitting reaction occurs during photosynthesis. Later, the gases can be recombined in a fuel cell to produce carbon-free electricity.

Electolysers which split water are already used industrially, but are extremely costly and do not work in everyday conditions.

The new process is cheap and operates at room temperature, with neutral acidity water.

Professor Daniel Nocera, from the Massachusetts Institute of Technology in Boston, who co-led the research, said: "Solar power has always been a limited, far-off solution. Now we can seriously think about solar power as unlimited, and soon."

British expert Professor James Barber, from Imperial College London, said the technology represented a "giant leap" towards generating clean, carbon-free energy on a massive scale.

"This is a major discovery with enormous implications for the future prosperity of humankind," he said. "It opens up the door for developing new technologies for energy production thus reducing our dependence for fossil fuels and addressing the global climate change problem."

More work needs to be done to integrate the new technology into existing solar power systems. But Prof Nocera believes that within 10 years people will be able to power their homes with a combination of solar panels and household fuel cells.

Ontario introduces new 'ultra-low' overnight hydro pricing

Ontario Ultra-Low Overnight Electricity Rates cut costs for shift workers and EV charging, with time-of-use pricing, off-peak savings, on-peak premiums, kilowatt-hour details, and Ontario Energy Board guidance for homes and businesses across participating utilities.

 

Key Points

Ontario's ultra-low overnight plan: 2.4c/kWh 11pm-7am for EVs, shift workers; higher daytime on-peak pricing.

✅ 2.4c/kWh 11pm-7am; 24c/kWh on-peak 4pm-9pm

✅ Best for EV charging, shift work, night usage

✅ Available provincewide by Nov 1 via local utilities

 

The Ontario government is introducing a new ultra-low overnight price plan that can benefit shift workers and individuals who charge electric vehicles while they sleep.

Speaking at a news conference on Tuesday, Energy Minister Todd Smith said the new plan could save customers up to $90 a year.

“Consumer preferences are still changing and our government realized there was more we could do, especially as the province continues to have an excess supply of clean electricity at night when province-wide electricity demand is lower,” Smith said, noting a trend underscored by Ottawa's demand decline during the pandemic.

The new rate, which will be available as an opt-in option as of May 1, will be 2.4 cents per kilowatt-hour from 11 p.m. to 7 a.m. Officials say this is 67 per cent lower than the current off-peak rate, which saw a off-peak relief extension during the pandemic.

However, customers should be aware that this plan will mean a higher on-peak rate, as unlike earlier calls to cut peak rates, Hydro One peak charges remained unchanged for self-isolating customers.

The new plan will be offered by Toronto Hydro, London Hydro, Centre Wellington Hydro, Hearst Power, Renfrew Hydro, Wasaga Distribution, and Sioux Lookout Hydro by May. Officials have said this will be expanded to all local distribution companies by Nov. 1.

With the new addition of the “ultra low” pricing, there are now three different electricity plans that Ontarians can choose from. Here is what you have to know about the new hydro options:

TIME OF USE:
Most residential customers, businesses and farms are eligible for these rates, similar to BC Hydro time-of-use proposals in another province, which are divided into off-peak, mid-peak and on-peak hours.

This is what customers will pay as of May 1 according to the Ontario Energy Board, following earlier COVID-19 electricity relief measures that temporarily adjusted rates:

 Off-peak (Weekdays between 7 p.m. and 7 a.m. and on weekends/holidays): 7.4 cents per kilowatt-hour
 Mid-Peak (Weekdays between 7 a.m. and 11 a.m., and between 5 p.m. and 7 p.m.): 10.2 cents per kilowatt-hour
 On-Peak ( Weekdays 11 a.m. to 5 p.m.): 15.1 cents per kilowatt-hour

TIERED RATES
This plan allows customers to get a standard rate depending on how much electricity is used. There are various thresholds per tier, and once a household exceeds that threshold, a higher price applies. Officials say this option may be beneficial for retirees who are home often during the day or those who use less electricity overall.

The tiers change depending on the season. This is what customers will pay as of May 1:

 Residential households that use 600 kilowatts of electricity per month and non-residential businesses that use 750 kilowatts per month: 8.7 cents per kilowatt-hour.
 Residences and businesses that use more than that will pay a flat rate of 10.3 cents per kilowatt-hour


ULTRA-LOW OVERNIGHT RATES
Customers can opt-in to this plan if they use most of their electricity overnight.

This is what customers will pay as of May 1:

  •  Between 11 p.m. and 7 a.m.: 2.4 cents per kilowatt-hour
  •  Weekends and holidays between 7 a.m. and 11 p.m.: 7.4 cents per kilowatt-hour
  •  Mid-Peak (Weekdays between 7 a.m. and 4 p.m., and between 9 p.m. and 11 p.m.): 10.2 cents per kilowatt-hour
  •  On-Peak (weekdays between 4 p.m. and 9 p.m.): 24 cents per kilowatt-hour

More information on these plans can be found on the Ontario Energy Board website, alongside stable pricing for industrial and commercial updates from the province.

Power firms win UK subsidies for new Channel cables project

UK Electricity Interconnectors secure capacity market subsidies, supporting winter reliability with seabed cables to France and Belgium via the Channel Tunnel, lowering consumer costs, squeezing coal, and challenging new gas plants through cross-border energy trading.

 

Key Points

High-voltage cables linking Britain to Europe, securing backup capacity, cutting costs and boosting winter reliability.

✅ Won capacity market contracts at record-low prices

✅ Cables to France and Belgium via Channel Tunnel, seabed routes

✅ Squeezes coal, challenges new gas; renewables may join market

 

New electricity cables across the Channel to France and Belgium will be a key part of keeping Britain’s lights on during winter amid record electricity prices across Europe in the early 2020s, after their owners won backup power subsidies in a government auction this week.

For the first time, interconnector operators successfully bid for a slice of hundreds of millions’ worth of contracts in the capacity market. That will help cut costs for consumers, given how electricity is priced in Europe today, and squeeze out old coal power plants.

Three new interconnectors are currently being built to Europe, almost doubling existing capacity, with one along the Channel Tunnel and two on the seabed: one between Kent and Zeebrugge and one from Hampshire to Normandy. 

The interconnectors were success stories in this week’s capacity auction, which saw power firms bid to provide backup electricity in the winter of 2021/22. Prices for the four-year contracts hit a record low of £8.40 per kilowatt per year, which analysts described as a shock and well below expectations.

One industry source said the figure was “miles away” from what is needed to encourage companies to build big new gas power stations, which some argue are necessary to fill the gap when the UK’s ageing nuclear reactors close as Europe loses nuclear power across the region over the next decade.

While bad news for those firms, the low price is good for consumers. The subsidies will add about £525m to energy bills, or £5.68 for the average household, compared with £11 for the year before, according to analysts Cornwall Insight.

Existing gas power stations scooped up most of the contracts, but new gas ones lost out, as did several coal plants. Battery storage plants, a standout success in the last auction, fared comparatively poorly after changes to the rules.

Experts at Bernstein bank said the the misses by coal meant that around half the UK’s remaining coal power capacity could close from October 2019, when existing capacity market contracts run out. Chaitanya Kumar, policy adviser at thinktank Green Alliance, said: “Coal’s exit from the UK’s energy system just moved a step closer as coal contracts fell by half compared with last year.”

Tom Edwards, an analyst at Cornwall Insight, said that more interconnectors were likely to bid into future rounds of the capacity market, such as the cable being laid between Norway and the UK. Relying on foreign power supplies was fine, he said, provided Brexit did not make energy trading more difficult and the interconnectors delivered at times of need, where events like Irish grid price spikes illustrate the stress points.

However, one industry source, who wants to see new gas plants built in the UK, said the results showed that the system was not working, amid UK peak power prices that have climbed in recent trading. “That self-sufficiency doesn’t seem to be a priority at a time when we’re breaking away from Europe is a bit weird,” they said.

But the prospects for new gas plants in future rounds of the capacity market look bleak. They will very likely face a new source of competition next year, if energy regulator Ofgem approves a proposal to allow renewables to compete too.

Let’s make post-COVID Canada a manufacturing hub again

Canada Manufacturing Policy prioritizes affordable energy, trims carbon taxes, aligns with Buy America, and supports the resource sector, PPE and plastics supply, nearshoring, and resilient supply chains amid COVID-19, correcting costly green energy policies.

 

Key Points

A policy to boost industry with affordable energy, lower carbon taxes, resource ties, and aligned U.S. trade.

✅ Cuts energy costs and carbon tax burdens for competitiveness

✅ Rebuilds resource-sector linkages and domestic supply chains

✅ Seeks Buy America relief and clarity on plastics regulation

 

By Jocelyn Bamford

Since its inception in 2017, the Coalition of Concerned Manufacturers and Businesses has warned all levels of government that there would be catastrophic effects if policies that drove both the manufacturing and natural resources sectors out of the country were adopted.

The very origins of our coalition was in the fight for a competitive landscape in Ontario, a cornerstone of which is affordable energy and sounding the alarm that the Green Energy Policy in Ontario pushed many manufacturers out of the province.


The Green Energy Policy made electricity in Ontario four times the average North American rate. These unjust prices were largely there to subsidize the construction of expensive and inefficient wind and solar energy infrastructure, even as cleaning up Canada's grid is cited as critical to meeting climate pledges.

My company’s November hydro bill was $55,000 and $36,500 of that was the so-called global adjustment charge, the name given to these green energy costs.

Unaffordable electricity, illustrated by higher Alberta power costs in recent years, coupled with ever-more burdensome carbon taxes, have pushed Canadian manufacturing into the open arms of other countries that see the importance of affordable energy to attract business.

One can’t help but ask the question: If Canada had policies that attracted and maintained a robust manufacturing sector, would we be in the same situation with a lack of personal protective equipment and medical supplies for our front-line medical workers and our patients during this pandemic?  If our manufacturing sector wasn’t crippled by taxes and regulation, would it be more nimble and able to respond to a national emergency?

It seems that the federal government’s policies are designed to push manufacturing out, stifle our resource sector, and kill the very plastics industry that is so essential to keeping our front-line medical staff, patients, and citizens safe, even as the net-zero race accelerates federally.

As the federal government chased its obsession with a new green economy – a strange obsession given our country’s small contribution to global GHGs – including proposals for a fully renewable grid by 2030 advocated by some leaders, it has been blinded from the real threats to our country, threats that became very, very real with COVID-19.

After the pandemic has passed, the federal government must work to make Canada manufacturing and resource friendly again, recognizing that the IEA net-zero electricity report projects the need for more power. COVID-19 proves that Canada relies on a robust resource economy and manufacturing sector to survive. We need to ensure that we are prepared for future crises like the one we are facing now.

Here are five things our government can do now to meet that end:

1. End all carbon taxes immediately.

2. Create a mandate to bring manufacturing back to Canada through competitive offerings and favourable tax regimes.

3. Recognize the interconnections between the resource sector and manufacturing, including how fossil-fuel workers support the transition across supply chains. Many manufacturers supply parts and pieces to the resource sector, and they rely on affordable energy to compete globally.

4. Stop the current federal government initiative to label plastic as toxic. At a time when the government is appealing to manufacturers to re-tool and produce needed plastic products for the health care sector, labelling plastics as toxic is counterproductive.

5. Work to secure a Canadian exemption to Buy America. This crisis has clearly shown us that dependency on China is dangerous. We must forge closer ties with America and work as a trading block in order to be more self-sufficient.

These are troubling times. Many businesses will not survive.

We need to take back our manufacturing sector.  We need to take back our resource sector.

We need to understand the interconnected nature of these two important segments of our gross domestic production, and opportunities like an Alberta–B.C. grid link to strengthen reliability.
If we do not, in the next pandemic we may find ourselves not only without ventilators, masks and gowns but also without energy to operate our hospitals.

Jocelyn Bamford is a Toronto business executive and President of the Coalition of Concerned Manufacturers and Businesses of Canada

Quebec Halts Crypto Mining Electricity Requests

Hydro-Quebec Crypto Mining Pause signals a temporary halt as blockchain power requests surge; energy regulator review will weigh electricity demand, winter peak constraints, tariffs, investments, and local jobs to optimize grid stability and revenues.

 

Key Points

A provincial halt on new miner power requests as Hydro-Quebec sets rules to safeguard demand, winter peaks, and rates.

✅ Temporary halt on new electricity sales to crypto miners

✅ Regulator to rank projects by jobs, investment, and revenue

✅ Winter peak demand and tariffs central to new framework

 

Major Canadian electricity provider Hydro-Québec will temporarily stop processing requests from cryptocurrency miners in order for the company to fulfil its obligations to supply energy to the entire province, while its global ambitions adjust to changing demand, according to a press release published June 7.

Hydro-Québec is experiencing “unprecedented” demand from blockchain companies, which reportedly exceeds the electric utility’s short and medium-term capacity. In this regard, the Quebec provincial government has ordered Hydro-Québec to halt electric power sales to cryptocurrency miners, and, following the New Hampshire rejection of Northern Pass announced a new framework for this category of electricity consumers.

In the coming days, Hydro-Québec will reportedly file an application to local energy regulator Régie de l'énergie, proposing a selection process for blockchain industry projects so as “not to miss the opportunities offered by this industry.” Regulators will reportedly target companies which can offer the province the most profitable economic advantages, including investments and local job creation.

#google#

Régie de l'énergie is instructed to consider “the need for a reserved block of energy for this category of consumers, the possibility of maximizing Hydro-Québec's revenues, and issues related to the winter peak period” as well as interprovincial arrangements like the Ontario-Québec electricity deal under discussion. Éric Filion, President of Hydro-Québec Distribution, said:

"The blockchain industry is a promising avenue for Hydro-Québec. Guidelines are nevertheless required to ensure that the development of this industry maximizes spinoffs for Québec without resulting in rate increases for our customers. We are actively participating in the Régie de l'énergie's process so that these guidelines can be produced as quickly as possible."

With this move, the government of Québec deviates from its decision to reportedly open the electricity market to miners at the end of last month, even as an Ontario-Quebec energy swap helps manage electricity demands. In March, the government said it was not interested in providing cheap electricity to Bitcoin miners, stating that cryptocurrency mining at a discount without any sort of “added value” for the local economy was unfavorable.

Duke Energy will spend US$25bn to modernise its US grid

Duke Energy Clean Energy Strategy targets smart grid upgrades, wind and solar expansion, efficient gas, and high-reliability nuclear, cutting CO2, boosting decarbonization, and advancing energy efficiency and reliability for the Carolinas.

 

Key Points

A plan investing in smart grids, renewables, gas, and nuclear to cut CO2 and enhance reliability and efficiency by 2030.

✅ US$25bn smart grid upgrades; US$11bn renewables and gas

✅ 40% CO2 reduction and >80% low-/zero-carbon generation by 2030

✅ 2017 nuclear fleet 95.64% capacity factor; ~90 TWh carbon-free

 

The US power group Duke Energy plans to invest US$25bn on grid modernization over the 2017-2026 period, including the implementation of smart grid technologies to cope with the development of renewable energies, along with US$11bn on the expansion of renewable (wind and solar) and gas-fired power generation capacities.

The company will modernize its fleet and expects more than 80% of its power generation mix to come from zero and lower CO2 emitting sources, aligning with nuclear and net-zero goals, by 2030. Its current strategy focuses on cutting down CO2 emissions by 40% by 2030. Duke Energy will also promote energy efficiency and expects cumulative energy savings - based on the expansion of existing programmes - to grow to 22 TWh by 2030, i.e. the equivalent to the annual usage of 1.8 million households.

#google#

Duke Energy’s 11 nuclear generating units posted strong operating performance in 2017, as U.S. nuclear costs hit a ten-year low, providing the Carolinas with nearly 90 billion kilowatt-hours of carbon-free electricity – enough to power more than 7 million homes.

Globally, China's nuclear program remains on a steady development track, underscoring broader industry momentum.

“Much of our 2017 success is due to our focus on safety and work efficiencies identified by our nuclear employees, along with ongoing emphasis on planning and executing refueling outages to increase our fleet’s availability for producing electricity,” said Preston Gillespie, Duke Energy chief nuclear officer.

Some of the nuclear fleet’s 2017 accomplishments include, as a new U.S. reactor comes online nationally:

  • The 11 units achieved a combined capacity factor of 95.64 percent, second only to the fleet’s 2016 record of 95.72 percent, marking the 19th consecutive year of attaining a 90-plus percent capacity factor (a measure of reliability).
  • The two units at Catawba Nuclear Station produced more than 19 billion kilowatt-hours of electricity, and the single unit at Harris Nuclear Plant generated more than 8 billion kilowatt-hours, both setting 12-month records.
  • Brunswick Nuclear Plant unit 2 achieved a record operating run.
  • Both McGuire Nuclear Station units completed their shortest refueling outages ever and unit 1 recorded its longest operating run.
  • Oconee Nuclear Station unit 2 achieved a fleet record operating run.

The Robinson Nuclear Plant team completed the station’s 30th refueling outage, which included a main generator stator replacement and other life-extension activities, well ahead of schedule.

“Our nuclear employees are committed to providing reliable, clean electricity every day for our Carolinas customers,” added Gillespie. “We are very proud of our team’s 2017 accomplishments and continue to look for additional opportunities to further enhance operations.”

A New Electric Boat Club Launches in Seattle

Aurelia Boat Club delivers electric boat membership in Seattle, featuring zero-emission propulsion, quiet cruising, sustainable recreation, and a managed fleet with maintenance, insurance, moorage, and charging handled for members seeking hassle-free, eco-friendly boating.

 

Key Points

Aurelia Boat Club is a Seattle membership offering all-electric boats, with maintenance, insurance, and moorage included.

✅ Unlimited access to an all-electric fleet

✅ Maintenance, insurance, moorage, and charging included

✅ Quiet, zero-emission cruising on Seattle waters

 

Seattle's maritime scene has welcomed a new player: Aurelia Boat Club. Founded by former Pure Watercraft employees, Aurelia is poised to redefine electric boating in the city, where initiatives like Washington State Ferries hybrid-electric upgrade are underway. The club's inception follows the unexpected closure of Pure Watercraft, a Seattle-based startup that aimed to revolutionize the pleasure boating industry before its financial troubles led to its downfall.

From Pure Watercraft to Aurelia Boat Club

Pure Watercraft, established in 2011, garnered attention for its innovative electric propulsion systems designed to replace traditional gas-powered motors in boats, while efforts to build the first commercial electric speedboats also advanced. The company attracted significant investment, including a notable partnership with General Motors in 2021, which acquired a 25% stake in Pure Watercraft. Despite these efforts, Pure Watercraft faced financial difficulties and entered receivership in 2024, leading to the liquidation of its assets. 

Amidst this transition, Danylo Kurgan and Mrugesh Desai saw an opportunity to continue the vision of electric boating. Kurgan, formerly a financial analyst at Pure Watercraft and involved in the company's boat club operations, teamed up with Desai, a technology executive and startup investor. Together, they acquired key assets from Pure Watercraft's receivership, including electric outboard motors, pontoon boats, inflatable crafts, battery systems, spare parts, and digital infrastructure. 

Aurelia Boat Club's Offerings

Aurelia Boat Club aims to provide a sustainable and accessible alternative to traditional gas-powered boat clubs in Seattle. Members can enjoy unlimited access to a fleet of all-electric boats without the responsibilities of ownership. The club's boats are equipped with electric motors, offering a quiet and environmentally friendly boating experience, similar to how electric ships are clearing the air on the B.C. coast. Additionally, Aurelia handles maintenance, repairs, insurance, and moorage, allowing members to focus solely on enjoying their time on the water. 

The Future of Electric Boating in Seattle

Aurelia Boat Club's launch signifies a growing interest in sustainable boating practices in Seattle. The club's founders are committed to scaling the business and expanding their fleet to meet the increasing demand for eco-friendly recreational activities, as projects like battery-electric high-speed ferries indicate. By leveraging the assets and knowledge gained from Pure Watercraft, Aurelia aims to continue the legacy of innovation in the electric boating industry.

As the boating community becomes more environmentally conscious, initiatives like Aurelia Boat Club play a crucial role in promoting sustainable practices, and examples such as Harbour Air's electric aircraft highlight the momentum. The club's success could serve as a model for other cities, demonstrating that with the right vision and resources, the transition to electric boating is not only feasible but also desirable.

While the closure of Pure Watercraft marked the end of one chapter, it also paved the way for new ventures like Aurelia Boat Club to carry forward the mission of transforming the boating industry, with regional moves like the Kootenay Lake electric-ready ferry and international innovations such as Berlin electric flying ferry showing what's possible. With a strong foundation and a clear vision, Aurelia is set to make significant waves in Seattle's electric boating scene.
