✅ 1,830-kW array offsets 1,000+ tonnes GHG annually

✅ Supplies ~8% of annual power; saves $200k-$300k per year

✅ 4,574 rooftop panels installed by Enmax in Acheson

Electricity consumption is one of the biggest barriers to going green in the cannabis industry, where the energy demands of cannabis cultivation often complicate sustainability, but an Edmonton-area pot producer has come up with a sunny solution.

Freedom Cannabis unveiled the largest rooftop solar system used by a cannabis facility in Canada at its 126,000-square foot Acheson location, 20 kilometres west of Edmonton, as solar power in Alberta continues to surge, on Tuesday.

The "state-of-the-art" 1,830-kilowatt solar array—made up of 4,574 panels—was supplied by Enmax and will offset more than 1,000 tonnes of greenhouse gas emissions each year, reflecting how new Alberta solar facilities are undercutting natural gas on price, the company said.

That will supply roughly eight per cent of the building's annual power consumption and reduce costs by $200,000 to $300,000 annually.

"This strategy will supplement our operating costs for power by up to eight to 10 per cent, so it is something that in time will save us costs on power requirements," said Troy Dezwart, co-founder of Freedom Cannabis.

Dezwart said sustainability was an important issue to the company from its outset, aligning with an Alberta renewable energy surge that is expected to power thousands of jobs.

"We're fortunate enough to be able to have these types of options and pursue them," said Dezwart.

The entire system cost Freedom Cannabis $2.6 million to build, but nearly a million of that came from a provincial rebate program that has since been cancelled by the UCP government, even as a federal green electricity deal with an Edmonton company signals ongoing support.

The company cited a 2017 report that found cannabis growers in the U.S. used enough electricity to power 1.7-million homes, and said cannabis-related power consumption is expected to increase by 1,250 per cent in Ontario over the next five years, even though Canadian solar demand has been lagging overall.

“It’s more important than ever for businesses to manage their energy footprint, and solar is an important part of that solution,” Enmax director Jason Atkinson, said. “This solar installation will help reduce operating costs and offset a significant portion of GHG emissions for decades to come.”

Freedom says it has other initiatives underway to reduce its footprint, in a region planning the Edmonton airport solar farm among other projects, including water remediation and offering 100 per cent recyclable cannabis packaging tins.

The company's first crops are expected to go to market in December.

Ireland electricity support measures include PSO levy rebates, RESS 2 renewables, CRU-directed EirGrid backup capacity, and grid investment for the Celtic Interconnector, cutting bills, boosting security of supply, and reducing reliance on imported fossil fuels.

Key Points

Government steps to cut bills and secure supply via PSO rebates, RESS 2 renewables, backup power, and grid upgrades.

✅ PSO levy rebates lower domestic electricity bills.

✅ RESS 2 adds wind, solar, and hydro to the grid.

✅ EirGrid to procure temporary backup capacity for winter peaks.

Ireland's Cabinet has approved a package of measures to help mitigate the rising cost of rising electricity bills, as Irish provider price increases continue to pressure consumers, and to ensure secure supplies to electricity for households and business across Ireland over the coming years.

The package of measures includes changes to the Public Service Obligation (PSO) levy (beyond those announced earlier in the year), which align with emerging EU plans for more fixed-price electricity contracts to improve price stability. The changes will result in rebates, and thus savings, for domestic electricity bills over the course of the next PSO year beginning in October. This further reduction in the PSO levy occurs because of a fall in the relative cost of renewable energy, compared to fossil fuel generation.

The Government has also approved the final results of the second onshore Renewable Electricity Support Scheme (RESS 2) auction, echoing how Ontario's electricity auctions have aimed to lower costs for consumers. This will bring significantly more indigenous wind, solar and hydro-electric energy onto the National Grid. This, in turn, will reduce our reliance on increasingly expensive imported fossil fuels, as the UK explores ending the gas-electricity price link to curb bills.

The package also includes Government approval for the provision of funding for back-up generation capacity, to address risks to security of electricity supply over the coming winters, similar to the UK's forthcoming energy security law approach in this area. The Commission for the Regulation of Utilities (CRU), which has statutory responsibility for security of supply, has directed EirGrid to procure additional temporary emergency generation capacity (for the winters of 2023/2024 to 2025/2026). This will ultimately provide flexible and temporary back-up capacity, to safeguard secure supplies of electricity for households and businesses as we deploy longer-term generation capacity.

Today’s measures also see an increased borrowing limit (€3 billion) for EirGrid – to strengthen our National Grid as part of 'Shaping Our Electricity Future' and to deliver the Celtic (Ireland-France) Interconnector, amid wider European moves to revamp the electricity market that could enhance cross-border resilience. An increased borrowing limit (€650 million) for Bord na Móna will drive greater deployment of indigenous renewable energy across the Midlands and beyond – as part of its 'Brown to Green' strategy, while measures like the UK's household energy price cap illustrate the scale of consumer support elsewhere.

Canadian Clean Hydrogen is surging, driven by net-zero goals, tax credits, and exports. Fuel cells, electrolysis, and low-emissions power and transport signal growth, though current production is largely fossil-based and needs decarbonization.

Key Points

Canadian Clean Hydrogen is the shift to make and use low-emissions hydrogen for energy and industry to reach net-zero.

✅ $17B tax credits through 2035 to scale electrolyzers and hubs

✅ Export MOUs with Germany and the Netherlands target 2025 shipments

✅ IEA: 99% of hydrogen from fossil fuels; deep decarbonization needed

As the world races to find effective climate solutions, and toward an electric planet vision, hydrogen is earning buzz as a potentially low-emitting alternative fuel source. 

The promise of hydrogen as a clean fuel source is nothing new — as far back as the 1970s hydrogen was being promised as a "potential pollution-free fuel for our cars."

While hydrogen hasn't yet taken off as the fuel of the future  — a 2023 report from McKinsey & Company and the Hydrogen Council estimates that there is a grand total of eight hydrogen vehicle fuelling stations in Canada — many still hope that will change.

The hope is hydrogen will play a significant role in combating climate change, serving as a low-emissions substitute for fossil fuels in power generation, home heating and transportation, where cleaning up electricity remains critical, and today, interest in a Canadian clean hydrogen industry may be starting to bubble over.

"People are super excited about hydrogen because of the opportunity to use it as a clean chemical fuel. So, as a displacement for natural gas, diesel, gasoline, jet fuel," said Andrew Gillis, CEO of Canadian hydrogen company Aurora Hydrogen. 

Plans for low or zero-emissions hydrogen projects are beginning to take shape across the country. But, at the moment, hydrogen is far from a low-emissions fuel, which is why some experts suggest expectations for the resource should be tempered. 

The IEA report indicates that in 2021, global hydrogen production emitted 900 million tonnes of carbon dioxide — roughly 180 million more than the aviation industry — as roughly 99 per cent of hydrogen production came from fossil fuel sources. 

"There is a concern that the role of hydrogen in the process of decarbonization is being very greatly overstated," said Mark Winfield, professor of environmental and urban change at York University. 

A growing excitement 

In 2020, the government released a hydrogen strategy, aiming to "cement hydrogen as a tool to achieve our goal of net-zero emissions by 2050 and position Canada as a global, industrial leader of clean renewable fuels." 

The latest budget includes over $17 billion in tax credits between now and 2035 to help fund clean hydrogen projects.

Today, the most common application for hydrogen in Canada is as a material in industrial activities such as oil refining and ammonia, methanol and steel production, according to Natural Resources Canada. 

But, the buzz around hydrogen isn't exactly over its industrial applications, said Aurora Hydrogen's Gillis.

"All these sorts of things where we currently have emitting gaseous or liquid chemical fuels, hydrogen's an opportunity to replace those and access the energy without creating emissions at the point of us," Gillis said. 

When used in a fuel cell, hydrogen can produce electricity for transportation, heating and power generation without producing common harmful emissions like nitrogen oxide, hydrocarbons and particulate matter — BloombergNEF estimates that hydrogen could meet 24 per cent of global energy demand by 2050.

A growing industry

Canada's hydrogen strategy aims to have 30 per cent of end-use energy be from clean hydrogen by 2050. According to the strategy, Canada produces an estimated three million tonnes of hydrogen per year from natural gas today, but the strategy doesn't indicate how much hydrogen is produced from low-emissions sources.

In recent years, the Canadian clean hydrogen industry has earned international interest, especially as Germany's hydrogen strategy anticipates significant imports.

In 2021, Canada signed a memorandum of understanding with the Netherlands to help develop "export-import corridors for clean hydrogen" between the two countries. Canada also recently inked a deal with Germany to start exporting the resource there by 2025.

But while a low-emissions hydrogen plant went online in Becancour, Que., in 2021, the rest of Canada's clean-hydrogen industry seems to be in the early stages.

CO2 Tax for UK Offshore Energy Efficiency can accelerate adoption of aero-derivative gas turbines, flare gas recovery, and combined cycle power, reducing emissions on platforms like Equinor's Mariner and supporting net zero goals.

Key Points

A carbon price pushing operators to adopt efficient turbines, flare recovery, and combined cycle to cut emissions.

✅ Aero-derivative turbines beat industrial units on efficiency

✅ Flare gas recovery cuts routine flaring and fuel waste

✅ Combined cycle raises efficiency and lowers emissions

By Tom Baxter

The recent Energy Voice article from the Equinor chairman concerning the Mariner project heralding a ‘significant point of reference’ for growth highlighted the energy efficiency achievements associated with the platform.

I view energy efficiency as a key enabler to net zero, and alongside this the UK must start large-scale storage to meet system needs; it is a topic I have been involved with for many years.

As part of my energy efficiency work, I investigated Norwegian practices and compared them with the UK.

There were many differences, here are three;

1. Power for offshore installations is usually supplied from gas turbines burning fuel from the oil and gas processing plant, and even as the UK's offshore wind supply accelerates, installations convert that to electricity or couple the gas turbine to a machine such as a gas compressor.

There are two main generic types of gas turbine – aero-derivative and industrial. As the name implies aero-derivatives are aviation engines used in a static environment. Aero-derivative turbines are designed to be energy efficient as that is very import for the aviation industry.

Not so with industrial type gas turbines; they are typically 5-10% less efficient than a comparable aero-derivative.

Industrial machines do have some advantages – they can be cheaper, require less frequent maintenance, they have a wide fuel composition tolerance and they can be procured within a shorter time frame.

My comparison showed that aero-derivative machines prevailed in Norway because of the energy efficiency advantages – not the case in the UK where there are many more offshore industrial gas turbines.

Tom Baxter is visiting professor of chemical engineering at Strathclyde University and a retired technical director at Genesis Oil and Gas Consultants

2. Offshore gas flaring is probably the most obvious source of inefficient use of energy with consequent greenhouse gas emissions.

On UK installations gas is always flared due to the design of the oil and gas processing plant.

Though not a large quantity of gas, a continuous flow of gas is routinely sent to flare from some of the process plant.

In addition the flare requires pilot flames to be maintained burning at all times and, while Europe explores electricity storage in gas pipes, a purge of hydrocarbon gas is introduced into the pipes to prevent unsafe air ingress that could lead to an explosive mixture.

On many Norwegian installations the flare system is designed differently. Flare gas recovery systems are deployed which results in no flaring during continuous operations.

Flare gas recovery systems improve energy efficiency but they are costly and add additional operational complexity.

3. Returning to gas turbines, all UK offshore gas turbines are open cycle – gas is burned to produce energy and the very hot exhaust gases are vented to the atmosphere. Around 60 -70% of the energy is lost in the exhaust gases.

Some UK fields use this hot gas as a heat source for some of the oil and gas treatment operations hence improving energy efficiency.

There is another option for gas turbines that will significantly improve energy efficiency – combined cycle, and in parallel plans for nuclear power under the green industrial revolution aim to decarbonise supply.

Here the exhaust gases from an open cycle machine are taken to a separate turbine. This additional turbine utilises exhaust heat to produce steam with the steam used to drive a second turbine to generate supplementary electricity. It is the system used in most UK power stations, even as UK low-carbon generation stalled in 2019 across the grid.

Open cycle gas turbines are around 30 – 40% efficient whereas combined cycle turbines are typically 50 – 60%. Clearly deploying a combined cycle will result in a huge greenhouse gas saving.

I have worked on the development of many UK oil and gas fields and combined cycle has rarely been considered.

The reason being is that, despite the clear energy saving, they are too costly and complex to justify deploying offshore.

However that is not the case in Norway where combined cycle is used on Oseberg, Snorre and Eldfisk.

What makes the improved Norwegian energy efficiency practices different from the UK – the answer is clear; the Norwegian CO2 tax.

A tax that makes CO2 a significant part of offshore operating costs.

The consequence being that deploying energy efficient technology is much easier to justify in Norway when compared to the UK.

Do we need a CO2 tax in the UK to meet net zero – I am convinced we do. I am in good company. BP, Shell, ExxonMobil and Total are supporting a carbon tax.

Not without justification there has been much criticism of Labour’s recent oil tax plans, alongside proposals for state-owned electricity generation that aim to reshape the power market.

To my mind Labour’s laudable aims to tackle the Climate Emergency would be much better served by supporting a CO2 tax that complements the UK's coal-free energy record by strengthening renewable investment.

Hinkley Point C dome lift marks a nuclear reactor milestone in Somerset, as EDF used Big Carl crane to place a 245-tonne steel roof, enabling 2027 startup amid costs, delays, and precision indoor welding.

Key Points

A 245-tonne dome lifted onto Hinkley Point C's first reactor, finishing the roof and enabling fit-out for a 2027 startup.

✅ 245-tonne steel dome lifted by Big Carl onto 44m-high reactor

✅ Indoor welding avoided weather defects seen at Flamanville

✅ Cost now £33bn; first power targeted by end of 2027

Engineers have lifted a steel roof onto a building which will house the first of two nuclear reactors at Hinkley Point in Somerset.

Hundreds of people helped with the delicate operation to get the 245-tonne steel dome into position.

It means the first reactor can be installed next year, ready to be switched on in June 2027.

Engineers at EDF said the "challenging job" was completed in just over an hour.

They first broke the ground on the new nuclear station in March 2017. Now, some 10,000 people work on what is Europe's largest building site.

Yet many analysts note that Europe is losing nuclear power even as demand for reliable energy grows.

They have faced delays from Covid restrictions and other recent setbacks, and the budget has doubled to £33bn, so getting the roof on the first of the two reactor buildings is a big deal.

EDF's nuclear island director Simon Parsons said it was a "fantastic night".

"Lifting the dome into place is a celebration of all the work done by a fantastic team. The smiles on people's faces this morning were something else.

"Now we can get on with the fitting of equipment, pipes and cables, including the first reactor which is on site and ready to be installed next year."

Nuclear minister Andrew Bowie hailed the "major milestone" in the building project, citing its role in the UK's green industrial revolution ambitions.

He said: "This is a key part of the UK Government's plans to revitalise nuclear."

But many still question whether Hinkley Point C will be worth all the money, especially after Hitachi's project freeze in Britain, with Roy Pumfrey of the Stop Hinkley campaign describing the project as "shockingly bad value".

Why lift the roof on?

The steel dome is bigger than the one on St Paul's Cathedral in London.

To lift it onto the 44-metre-high reactor building, they needed the world's largest land-based crane, dubbed Big Carl by engineers.

So why not just build the roof on top of the building?

The answer lies in a remote corner of Normandy in France, near a village called Flamanville.

EDF has been building a nuclear reactor there since 2007, ten years before they started in west Somerset.

The project is now a decade behind schedule and has still not been approved by French regulators.

Why? Because of cracks found in the precision welding on the roof of the reactor building.

In nuclear-powered France, they built the roof in situ, out in the open. 

Engineers have decided welding outside, exposed to wind and rain, compromised the high standards needed for a nuclear reactor.

So in Somerset they built a temporary workshop, which looks like a fair sized building itself. All the welding has been done inside, and then the completed roof was lifted into place.

Is it on time or on budget?

No, neither. When Hinkley C was first approved a decade ago, EDF said it would cost £14bn.

Four years later, in 2017, they finally started construction. By now the cost had risen to £19.5bn, and EDF said the plant would be finished by the end of 2025.

Today, the cost has risen to £33bn, and it is now hoped Hinkley C will produce electricity by the end of 2027.

"Nobody believes it will be done by 2027," said campaigner Roy Pumfrey.

"The costs keep rising, and the price of Hinkley's electricity will only get dearer," they added.

On the other hand, the increase in costs is not a problem for British energy bill payers, or the UK government.

EDF agreed to pay the full cost of construction, including any increases.

When I met Grant Shapps, then the UK Energy Secretary, at the site in April, he shrugged off the cost increases.

He said: "I think we should all be rather pleased it is not the British tax payer - it is France and EDF who are paying."

In return, the UK government agreed a set rate for Hinkley's power, called the Strike Price, back in 2013. The idea was this would guarantee the income from Hinkley Point for 35 years, allowing investors to get their money back.

Will it be worth the money?

Back in 2013, the Strike Price was set at £92.50 for each megawatt hour of power. At the time, the wholesale price of electricity was around £50/MWh, so Hinkley C looked expensive.

But since then, global shocks like the war in Ukraine have increased the cost of power substantially, and advocates argue next-gen nuclear could deliver smaller, cheaper, safer designs.

Baltic States EU Grid Synchronization strengthens energy independence and electricity security, ending IPS/UPS reliance. Backed by interconnectors like LitPol Link, NordBalt, and Estlink, it aligns with NATO interests and safeguards against subsea infrastructure threats.

Key Points

A shift by Estonia, Latvia, and Lithuania to join the EU grid, boosting energy security and reducing Russian leverage.

✅ Synchronized with EU grid on Feb 9, 2025 after islanding tests.

✅ New interconnectors: LitPol Link, NordBalt, Estlink upgrades.

✅ Reduces IPS/UPS risks; bolsters NATO and critical infrastructure.

In a landmark move towards greater energy independence and European integration, the Baltic nations of Estonia, Latvia, and Lithuania have officially disconnected from Russia's electricity grid, a path also seen in Ukraine's rapid grid link to the European system. This decisive action, completed in February 2025, not only ends decades of reliance on Russian energy but also enhances the region's energy security and aligns with broader geopolitical shifts.

Historical Context and Strategic Shift

Historically, the Baltic states were integrated into the Russian-controlled IPS/UPS power grid, a legacy of their Soviet past. However, in recent years, these nations have sought to extricate themselves from Russian influence, aiming to synchronize their power systems with the European Union (EU) grid. This transition gained urgency following Russia's annexation of Crimea in 2014 and further intensified after the invasion of Ukraine in 2022, as demonstrated by Russian strikes on Ukraine's grid that underscored energy vulnerability.

The Disconnection Process

The process culminated on February 8, 2025, when Estonia, Latvia, and Lithuania severed their electrical ties with Russia. For approximately 24 hours, the Baltic states operated in isolation, conducting rigorous tests to ensure system stability and resilience, echoing winter grid protection efforts seen elsewhere. On February 9, they successfully synchronized with the EU's continental power grid, marking a historic shift towards European energy integration.

Geopolitical and Security Implications

This transition holds significant geopolitical weight. By disconnecting from Russia's power grid, the Baltic states reduce potential leverage that Russia could exert through energy supplies. The move also aligns with NATO's strategic interests, enhancing the security of critical infrastructure in the region, amid concerns about Russian hacking of US utilities that highlight cyber risks.

Economic and Technical Challenges

The shift was not without challenges. The Baltic states had to invest heavily in infrastructure to ensure compatibility with the EU grid and navigate regional market pressures such as a Nordic grid blockade affecting transmission capacity. This included constructing new interconnectors and upgrading existing facilities. For instance, the LitPol Link between Lithuania and Poland, the NordBalt cable connecting Lithuania and Sweden, and the Estlink between Estonia and Finland were crucial in facilitating this transition.

Impact on Kaliningrad

The disconnection has left Russia's Kaliningrad exclave isolated from the Russian power grid, relying solely on imports from Lithuania. While Russia claims to have measures in place to maintain power stability in the region, the long-term implications remain uncertain.

Ongoing Security Concerns

The Baltic Sea region has experienced heightened security concerns, particularly regarding subsea cables and pipelines. Increased incidents of damage to these infrastructures have raised alarms about potential sabotage, including a Finland cable damage investigation into a suspected Russian-linked vessel. Authorities continue to investigate these incidents, emphasizing the need for robust protection of critical energy infrastructure.

The successful disconnection and synchronization represent a significant step in the Baltic states' journey towards full integration with European energy markets. This move is expected to enhance energy security, promote economic growth, and solidify geopolitical ties with the EU and NATO. As the region continues to modernize its energy infrastructure, ongoing vigilance against security threats will be paramount, as recent missile and drone attacks on Kyiv's grid demonstrate.

The Baltic states' decision to disconnect from Russia's power grid and synchronize with the European energy system is a pivotal moment in their post-Soviet transformation. This transition not only signifies a break from historical dependencies but also reinforces their commitment to European integration and collective security. As these nations continue to navigate complex geopolitical landscapes, their strides towards energy independence serve as a testament to their resilience and strategic vision.
