Reviving the AC/DC debate

Poland Offshore Wind Energy accelerates as PGE exits nuclear leadership, PKN Orlen steps in, and Baltic Sea projects expand to cut coal reliance, meet EU emissions goals, attract investors, and bridge the power capacity gap.

Key Points

A shift from coal and nuclear to Baltic offshore wind to add capacity, cut EU emissions, and attract investment.

✅ PGE drops lead in nuclear; pivots $10bn to offshore wind.

✅ PKN Orlen may assume nuclear role; projects await approval.

✅ 6 GW offshore could add 60b zlotys and 77k jobs by 2030.

PGE, Poland’s biggest power group has decided to abandon a role in building the country’s first nuclear power plant and will instead focus investment on offshore wind energy.

Reuters reports state-run refiner PKN Orlen (PKN.WA) could take on PGE’s role, while the latter announces a $10bn offshore wind power project.

Both moves into renewables and nuclear represent a major change in Polish energy policy, diversifying away from the country’s traditional coal-fired power base, as regional efforts like the North Sea wind farms initiative expand, in a bid to fill an electricity shortfall and meet EU emission standards.

An unnamed source told the news agency, PGE could not fund both projects and cheap technology had swung the decision in favour of wind, with offshore wind competing with gas in some markets. PGE could still play a smaller role in the nuclear project which has been delayed and still needs government approval.

A proposed law is currently before the Polish parliament aiming at facilitating easy construction of wind turbines, mindful of Germany’s grid expansion challenges that have hindered rollout.

If the law is passed, as expected, several other wind farm projects could also proceed.

Polenergia has said it would like to build a wind farm in the Baltic by 2022. PKN Orlen is also considering building one.

PGE said in March that it wants to build offshore windfarms with a capacity of 2.5 gigawatts (GW) by 2030.

Analysts and investors say that offshore wind farms are the easiest and fastest way for Poland to fill the expected capacity gap from coal, with examples like the largest UK offshore wind farm coming online underscoring momentum, and reduce CO2 emissions in line with EU’s 2030 targets as Poland seeks improved ties with Brussels.

The decision to open up the offshore power industry could also draw in investors, as shown by Japanese utilities’ UK offshore investment attracting cross-border capital. Statoil said in April it would join Polenergia’s offshore project which has drawn interest from other international wind companies. “

The Polish Wind Energy Association (PWEA) estimates that offshore windfarms with a total capacity of 6 GW would help create around 77,000 new jobs and add around 60 billion zlotys to economic growth.

Canada Tidal Energy Investment drives Nova Scotia's PLAT-I floating tidal array at FORCE, advancing renewable energy, clean electricity, emissions reductions, and green jobs while delivering 9 MW of predictable ocean power to the provincial grid.

Key Points

Federal funding for a floating tidal array delivering 9 MW of clean power in Nova Scotia, cutting annual CO2 emissions.

✅ $28.5M for Sustainable Marine's PLAT-I floating array

✅ Delivers 9 MW to Nova Scotia's grid via FORCE

✅ Cuts 17,000 tonnes CO2 yearly and creates local jobs

Canada has an abundance of renewable energy sources that are helping power our country's clean growth future and the Government of Canada is investing in renewable energy and grid modernization to reduce emissions, create jobs and invigorate local economies in a post COVID-19 pandemic world.

The Honourable Seamus O'Regan, Canada's Minister of Natural Resources, today announced one of Canada's largest-ever investments in tidal energy development — $28.5 million to Sustainable Marine in Nova Scotia to deliver Canada's first floating tidal energy array.

Sustainable Marine developed an innovative floating tidal energy platform called PLAT-I as part of advances in ocean and river power technologies that has undergone rigorous testing on the waters of Grand Passage for nearly two years. A second platform is currently being assembled in Meteghan, Nova Scotia and will be launched in Grand Passage later this year for testing before relocation to the Fundy Ocean Research Centre for Energy (FORCE) in 2021. These platforms will make up the tidal energy array.  

The objective of the project is to provide up to nine megawatts of predictable and clean renewable electricity to Nova Scotia's electrical grid infrastructure. This will reduce greenhouse gas emissions by 17,000 tonnes of carbon dioxide a year while creating new jobs in the province. The project will also demonstrate the ability to harness tides as a reliable source of renewable electricity to power homes, vehicles and businesses.

Tidal energy — a clean, renewable energy source generated by ocean tides and currents, alongside evolving offshore wind regulations that support marine renewables — has the potential to significantly reduce Canada's greenhouse gas emissions and improve local air quality by displacing electricity generated from fossil fuels.

Minister O'Regan made the announcement at the Marine Renewables Canada 2020 Fall Forum, which brings together its members and industry to identify opportunities and strategize a path forward for marine renewable energy sources.

Funding for the project comes from Natural Resources Canada's Emerging Renewables Power Program, part of Canada's more than $180-billion Investing in Canada infrastructure plan for public transit projects, green infrastructure, social infrastructure, trade and transportation routes and Canada's rural and northern communities, as Prairie provinces' renewable growth accelerates nationwide.

Germany Hydrogen-Ready Power Plants Tender accelerates the energy transition by enabling clean energy generation, decarbonization, and green hydrogen integration through retrofit and new-build capacity, resilient infrastructure, flexible storage, and grid reliability provisions.

Key Points

Germany tender to build or convert plants for hydrogen, advancing decarbonization, energy security, and clean power.

✅ Hydrogen-ready retrofits and new-build generation capacity

✅ Supports decarbonization, grid reliability, and flexible storage

✅ Future-proof design for green hydrogen supply integration

Germany, a global leader in energy transition and environmental sustainability, has recently launched an ambitious call for tenders aimed at developing hydrogen-ready power plants. This initiative is a significant step in the country's strategy to transform its energy infrastructure and support the broader goal of a greener economy. The move underscores Germany’s commitment to reducing greenhouse gas emissions and advancing clean energy technologies.

The Need for Hydrogen-Ready Power Plants

Hydrogen, often hailed as a key player in the future of clean energy, offers a promising solution for decarbonizing various sectors, including power generation. Unlike fossil fuels, hydrogen produces zero carbon emissions when used in fuel cells or burned. This makes it an ideal candidate for replacing conventional energy sources that contribute to climate change.

Germany’s push for hydrogen-ready power plants reflects the country’s recognition of hydrogen’s potential in achieving its climate goals. Traditional power plants, which typically rely on coal, natural gas, or oil, emit substantial amounts of CO2. Transitioning these plants to utilize hydrogen can significantly reduce their carbon footprint and align with Germany's climate targets.

The Details of the Tender

The recent tender call is part of Germany's broader strategy to incorporate hydrogen into its energy mix, amid a nuclear option debate in climate policy. The tender seeks proposals for power plants that can either be converted to use hydrogen or be built with hydrogen capability from the outset. This approach allows for flexibility and innovation in how hydrogen technology is integrated into existing and new energy infrastructures.

One of the critical aspects of this initiative is the focus on “hydrogen readiness.” This means that power plants must be designed or retrofitted to operate with hydrogen either exclusively or in combination with other fuels. The goal is to ensure that these facilities can adapt to the growing availability of hydrogen and seamlessly transition from conventional fuels without significant additional modifications.

By setting such requirements, Germany aims to stimulate the development of technologies that can handle hydrogen’s unique properties and ensure that the infrastructure is future-proofed. This includes addressing challenges related to hydrogen storage, transportation, and combustion, and exploring concepts like storing electricity in natural gas pipes for system flexibility.

Strategic Implications for Germany

Germany’s call for hydrogen-ready power plants has several strategic implications. First and foremost, it aligns with the country’s broader energy strategy, which emphasizes the need for a transition from fossil fuels to cleaner alternatives, building on its decision to phase out coal and nuclear domestically. As part of its commitment to the Paris Agreement and its own climate action plans, Germany has set ambitious targets for reducing greenhouse gas emissions and increasing the share of renewable energy in its energy mix.

Hydrogen plays a crucial role in this strategy, particularly for sectors where direct electrification is challenging. For instance, heavy industry and certain industrial processes, such as green steel production, require high-temperature heat that is difficult to achieve with electricity alone. Hydrogen can fill this gap, providing a cleaner alternative to natural gas and coal.

Moreover, this initiative helps Germany bolster its leadership in green technology and innovation. By investing in hydrogen infrastructure, Germany positions itself as a pioneer in the global energy transition, potentially influencing international standards and practices. The development of hydrogen-ready power plants also opens up new economic opportunities, including job creation in engineering, construction, and technology sectors.

Challenges and Opportunities

While the push for hydrogen-ready power plants presents significant opportunities, it also comes with challenges. Hydrogen production, especially green hydrogen produced from renewable sources, remains relatively expensive compared to conventional fuels. Scaling up production and reducing costs are critical for making hydrogen a viable alternative for widespread use.

Furthermore, integrating hydrogen into existing power infrastructure, alongside electricity grid expansion, requires careful planning and investment. Issues such as retrofitting existing plants, ensuring safe handling of hydrogen, and developing efficient storage and transportation systems must be addressed.

Despite these challenges, the long-term benefits of hydrogen integration are substantial, and a net-zero roadmap indicates electricity costs could fall by a third. Hydrogen can enhance energy security, reduce reliance on imported fossil fuels, and support global climate goals. For Germany, this initiative is a step towards realizing its vision of a sustainable, low-carbon energy system.

Conclusion

Germany’s call for hydrogen-ready power plants is a forward-thinking move that reflects its commitment to sustainability and innovation. By encouraging the development of infrastructure capable of using hydrogen, Germany is taking a significant step towards a cleaner energy future. While challenges remain, the strategic focus on hydrogen underscores Germany’s leadership in the global transition to a low-carbon economy. As the world grapples with the urgent need to address climate change, Germany’s approach serves as a model for integrating emerging technologies into national energy strategies.

Solid-State AC Switching reimagines electrification with silicon-based, firmware-driven controls, smart outlets, programmable circuit breakers, AC-DC conversion, and embedded sensors for IoT, energy monitoring, surge protection, and safer, globally compatible devices.

Key Points

Solid-state AC switching replaces mechanical switches with silicon chips for intelligent, programmable power control.

✅ Programmable breakers trip faster and add surge and GFCI protection

✅ Shrinks AC-DC conversion, boosting efficiency and device longevity

✅ Enables sensor-rich, IoT-ready outlets with energy monitoring

Electricity is a paradox. On the one hand, it powers our most modern clean cars and miracles of computing like your phone and laptop. On the other hand, it’s one of the least updated, despite efforts to build a smarter electricity infrastructure nationwide, and most ready-for-disruption parts of our homes, offices, and factories.

A startup in Silicon Valley plans to change all that, in California’s energy transition where reliability is top of mind, and has just signed deals with leading global electronics manufacturers to make it happen.

“The end point of the electrification infrastructure of every building out there right now is based on old technology,” Thar Casey, CEO of Amber Solutions, told me recently on the TechFirst podcast. “Basically some was invented ... last century and some came in a little bit later on in the fifties and sixties.”

Ultimately, it’s an almost 18th century part of modern homes.

Even smart homes, with add-ons like the Tesla Powerwall, still rely on legacy switching.

The fuses, breakers, light switches, and electrical outlets in your home are ancient technology that would easily understood by Thomas Edison, who was born in 1847. When you flip a switch and instantly flood your room with light, it feels like a modern right. But you are simply pushing a piece of plastic which physically moves one wire to touch another wire. That completes a circuit, electricity flows, and ... let there be light.

Casey wants to change all that. To transform our hard-wired electrical worlds and make them, in a sense, soft wired. And the addressable market is literally tens of billions of devices.

The core innovation is a transition to solid-state switches.

“Take your table, which is a solid piece of wood,” Casey says. “If you can mimic what an electromechanical switch does, opening and closing, inside that table without any actual moving parts, that means you are now solid state AC switching.”

And solid-state is exactly what Silicon Valley is all about.

“Solid state it means it can be silicon,” Casey says. “It can be a chip, it can be smaller, it can be intelligent, you can have firmware, you can add software ... now you have a mini computer.”

That’s a significant innovation with a huge number of implications. It means that the AC to DC converters attached to every appliance you plug into the wall — the big “bricks” that are part of your power cord, for instance — can now be a tiny fraction of the size. Appliance run on DC, direct current, and the electricity in your walls is AC, alternating current; similar principles underpin advanced smart inverters in solar systems, and it needs to be converted before it’s usable, and that chunk of hardware, with electrolytics, magnetics, transformers and more, can now be replaced, saving space in thermostats, CO2 sensors, coffee machines, hair dryers, smoke detectors ... any small electric device.

(Since those components generally fail before the device does, replacing them is a double win.)

Going solid state also means that you can have dynamic input range: 45 volts all the way up to 600 volts.

So you can standardize one component across many different electric devices, and it’ll work in the U.S., it’ll work in Europe, it’ll work in Japan, and it will work whether it’s getting 100 or 120 or 220 volts.

Building it small and building it solid state has other benefits as well, Casey says, including a much better circuit breaker for power spikes as the U.S. grid faces climate change impacts today.

“This circuit breaker is programmable, it has intelligence, it has WiFi, it has Bluetooth, it has energy monitoring metering, it has surge protection, it has GFCI, and here’s the best part: we trip 3000 times faster than a mechanical circuit breaker.”

What that means is much more ambient intelligence that can be applied all throughout your home. Rather than one CO2 sensor in one location, every power outlet is now a CO2 sensor that can feed virtual power plant programs, too. And a particulate matter sensor and temperature sensor and dampness sensor and ... you name it.

“We put as many as fifteen functions ... in one single gang box in a wall,” Casey told me.

Solid state is the gift that keeps giving, because now every outlet can be surge-protected. Every outlet can have GFCI — ground fault circuit interruption — not just the ones in your bathroom. And every outlet and light switch in your home can participate in the sensor network that powers your home security system. Oh, and, if you want, Alexa or Siri or the Google Assistant too. Plus energy-efficient dimmers for all lighting appliances that don’t buzz.

So when can you buy Amber switches and outlets?

In a sense, never.

Casey says Amber isn’t trying to be a consumer-facing company and won’t bring these innovations to market themselves. This July, Amber announced a letter of intent with a global manufacturer that includes revenue, plus MOUs with six other major electronics manufacturers. Letters of intent can be a dime a dozen, as can memoranda of understanding, but attaching revenue makes it more serious and significant.

The company has only raised $6.7 million, according to Craft, and has a number of competitors, such as Blixt, which has funding from the European Union, and Atom Power, which is already shipping technology. But since Amber is not trying to be a consumer product and take its innovations to market itself, it needs much less cash to build a brand and a market. You’ll be able to buy Amber’s technology at some point; just not under the Amber name.

“We have over 25 companies that we’re in discussions with,” Casey says. “We’re going to give them a complete solution and back them up and support them toward success. Their success will be our success at the end of the day.”

Ultimately, of course, cost will be a big part of the discussion.

There are literally tens of billions of switches and outlets on the planet, and modernizing all of them won’t happen overnight. And if it’s expensive, it won’t happen quickly either, even as California turns to grid-scale batteries to ease strain.

Casey is a big cagey with costs — there are still a lot of variables, after all. But it seems it won’t cost that much more than current technology.

“This can’t be $1.50 to manufacture, at least not right now, maybe down the road,” he told me. “We’re very competitive, we feel very good. We’re talking to these partners. They recognize that what we’re bringing, it’s a cost that is cost effective.”

Canada Clean Electricity Expansion is urged by the IEA to meet net-zero targets, scaling non-emitting generation, electrification, EV demand, and grid integration across provinces to decarbonize industry, buildings, and transport while ensuring reliability and affordability.

Key Points

An IEA-backed pathway for Canada to scale non-emitting power, electrification, and grid links to meet net-zero goals.

✅ Double or triple clean generation to replace fossil fuels

✅ Integrate provincial grids to decarbonize dependent regions

✅ Manage EV and heating loads with reliability and affordability

Canada will need more electricity capacity if it wants to hit its climate targets, and cleaning up Canada's electricity will be critical, according to a new report from the International Energy Agency (IEA).

The report offers mainly a rosy picture of Canada's overall federal energy policy. But, the IEA draws attention to Canada's increasing future electricity demands, and ultimately, calls on Canada to leverage its non-emitting energy potential and expand renewable energy to hit its climate targets.  

"Canada's wealth of clean electricity and its innovative spirit can help drive a secure and affordable transformation of its energy system and help realize its ambitious goals," stated Fatih Birol, the IEA executive director, in a news release.

The IEA notes that Canada has one of the cleanest energy grids globally, with 83 per cent of electricity coming from non-emitting sources in 2020. But this reflects nationwide progress in electricity to date; the report warns this is not a reason for Canada to rest on its laurels. More electricity will be needed to displace fossil fuels if Canada wants to hit its 2030 targets, the report states, and "even deeper cuts" will be required to reach net-zero by 2050.

"Perhaps more significantly, however, Canada will need to ensure sufficient new clean generation capacity to meet the sizeable levels of electrification that its net-zero targets imply."

Investing in new coal, oil and gas projects must stop to hit climate goals, global energy agency says
The Liberals have promised to create a 100 percent net-zero-emitting electricity system by 2035, with regulating oil and gas emissions and electric car sales as part of the plan; by then, every new light-duty vehicle sold in Canada will be a zero-emission vehicle. The switch from gas guzzlers to plug-in electric vehicles will create new pressures on Canada's electrical grid, as will any turn away from fossil natural gas for home heating.

To meet these challenges, the IEA warns, Canada would need to double or triple the power generated from non-emitting sources compared to today, a shift whose cost could reach $1.4 trillion according to the Canadian Gas Association. 

"Such a shift will require significant regulatory action," the report states, highlighting the need for climate policy for electricity grids to guide implementation, and that will require the federal government to work closely with provinces and territories that control power generation and distribution.

The report notes that the further integration of territorial and provincial electrical grids could allow fossil fuel-dependent provinces, like Alberta, to decarbonize and electrify their economies.

The report, entitled Canada 2022 Energy Policy Review, offers what it calls an "in-depth" look at the commitments Canada has made to transform its energy policy. Since the IEA conducted its last review in 2015, Canada has committed to cutting greenhouse gas emissions by 40 to 45 per cent from 2005 levels by 2030 and achieving net-zero by 2050 under an extended national target.

The IEA is well-known for the production of its annual World Energy Outlook. The Paris-based autonomous intergovernmental organization provides analysis, data, and policy recommendations to promote global energy security and sustainability. Canada is a part of the intergovernmental body, which also conducts peer reviews of its members' energy policy.

Oil and gas emissions rising
Natural Resources Minister Jonathan Wilkinson responded to the report in the IEA news release.

"This report acknowledges Canada's ambitious efforts and historic investments to develop pathways to achieve net-zero emissions by 2050 and ensure a transition that aligns with our shared objective of limiting global warming to 1.5 degrees Celsius," Wilkinson's statement read.

The report notes that — despite that objective — absolute emissions from Canadian oil and gas extraction went up 26 per cent between 2000 and 2019, largely from increased production.

"Canada will need to reconcile future growth in oil sands production with increasingly strict greenhouse gas requirements," the report states.

On the plus side, the IEA found emissions per barrel of oilsands crude have decreased by 20 per cent in the last decade from technical and operational improvements.

The improving carbon efficiency of the oilsands is a "trend that is expected to continue at even higher rates," said Ben Brunnen, vice-president of oilsands, fiscal and economic policy at the Canadian Association of Petroleum Producers.

That may become important, the IEA report notes, as energy investors and buyers look for low-carbon assets and more countries adopt net-zero policies.

Further innovation, such as carbon capture and storage, could help to turn things around for Canada's oil patch, the report says. The Liberals have also said they will place a hard cap on oil and gas emissions from production, but that does not include the burning of the fossil fuels. 

In 2021, the IEA released a report that determined to achieve net-zero by 2050, among many steps, investments needed to end in coal mines, oil and gas wells. Thursday's report, however, made no mention of that, which disappointed at least one environmental group.

"A glaring omission was that this assessment says nothing about production. We know that the most important thing we can do is to stop using and producing oil and gas," said Julia Levin, a senior climate and energy program manager at Environmental Defence.

"And yet that was absent from this report, and that really is a glaring omission, which is completely out of line with their [the IEA's] own work."

Energy Justice Program drives a renewables-based transition, challenging utility monopolies with legal action, promoting rooftop solar, distributed energy, public power, and climate justice to decarbonize the grid and protect communities and wildlife nationwide.

Key Points

A climate justice initiative advancing renewables, legal action, and public power to challenge utility monopolies.

✅ Challenges utility barriers to rooftop solar and distributed energy

✅ Advances state and federal policies for equitable, public power

✅ Uses litigation to curb fossil fuel dependence and protect communities

The Center for Biological Diversity on Monday rolled out a new program to push back against the nation's community- and wildlife-harming energy system that the climate advocacy group says is based on fossil fuels and a "centralized monopoly on power."

The goal of the new effort, the Energy Justice Program, is to help forge a path towards a just and renewables-based energy future informed by equitable regulation principles.

"Our broken energy system threatens our climate and our future," said Jean Su, the Energy Justice Program's new director, in a statement. "Utilities were given monopolies to ensure public access to electricity, but these dinosaur corporations are now hurting the public interest by blocking the clean energy transition, including via coal and nuclear subsidy schemes that profit off the fossil fuel era."

"In this era of climate catastrophe," she continued, "we have to stop these outdated monopolies and usher in a new electricity future that works for people and the planet."

To meet those goals, the new program will pursue a number of avenues, including using legal action to fight utilities' obstruction of clean energy efforts, helping communities advance local solar programs through energy freedom strategies in the South, and crafting energy policies on the state, federal, and international levels in step with commitments from major energy buyers to achieve a 90% carbon-free goal by 2030.

Some of that work is already underway. In June the Center filed a brief with a federal court in a bid to block Arizona power utility Salt River Project from slapping a 60-percent electricity rate hike on rooftop solar customers—amid federal efforts to reshape electricity pricing that critics say are being rushed—a move the group described (pdf) as an obstacle to achieving "the energy transition demanded by climate science."

The Center is among the groups in Energy Justice NC. The diverse coalition seeks to end the energy stranglehold in North Carolina held by Duke Energy, which continues to invest in fossil fuel projects even as it touts clean energy and grid investments in the region.

The time for a new energy system, says the Energy Justice Program, is now, as climate change impacts increasingly strain the grid.

"Amid this climate and extinction emergency," said Su, "the U.S. can't afford to stick with the same centralized, profit-driven electricity system that drove us here in the first place. We have to seize this once-in-a-generation opportunity to design a new system of accountable, equitable, truly public power."
