Two reactors going to Darlington

Wave Energy Converters can deliver marine power to the grid, with DOE-backed PacWave enabling offshore testing, robust designs, and renewable electricity from oscillating waves to decarbonize coastal communities and replace diesel in remote regions.

Key Points

Wave energy converters are devices that transform waves' oscillatory motion into electricity for the grid or loads.

✅ DOE's PacWave enables full-scale, grid-connected offshore testing.

✅ Multiple designs convert oscillating motion into torque and power.

✅ Ideal for islands, microgrids, and replacing diesel generation.

Waves off the coast of the U.S. could generate 2.64 trillion kilowatt hours of electricity per year — that’s about 64% of last year’s total utility-scale electricity generation in the U.S. We won’t need that much, but one day experts do hope that wave energy will comprise about 10-20% of our electricity mix, alongside other marine energy technologies under development today.

“Wave power is really the last missing piece to help us to transition to 100% renewables, ” said Marcus Lehmann, co-founder and CEO of CalWave Power Technologies, one of a number of promising startups focused on building wave energy converters.

But while scientists have long understood the power of waves, it’s proven difficult to build machines that can harness that energy, due to the violent movement and corrosive nature of the ocean, combined with the complex motion of waves themselves, even as a recent wave and tidal market analysis highlights steady advances.

″Winds and currents, they go in one direction. It’s very easy to spin a turbine or a windmill when you’ve got linear movement. The waves really aren’t linear. They’re oscillating. And so we have to be able to turn this oscillatory energy into some sort of catchable form,” said Burke Hales, professor of cceanography at Oregon State University and chief scientist at PacWave, a Department of Energy-funded wave energy test site off the Oregon Coast. Currently under construction, PacWave is set to become the nation’s first full-scale, grid-connected test facility for these technologies, a milestone that parallels U.K. wind power lessons on scaling new industries, when it comes online in the next few years.

“PacWave really represents for us an opportunity to address one of the most critical barriers to enabling wave energy, and that’s getting devices into the open ocean,” said Jennifer Garson, Director of the Water Power Technologies Office at the U.S. Department of Energy.

At the beginning of the year, the DOE announced $25 million in funding for eight wave energy projects to test their technology at PacWave, as offshore wind forecasts underscore the growing investor interest in ocean-based energy. We spoke with a number of these companies, which all have different approaches to turning the oscillatory motion of the waves into electrical power.

Different approaches
Of the eight projects, Bay Area-based CalWave received the largest amount, $7.5 million. 

″The device we’re testing at PacWave will be a larger version of this,” said Lehmann. The x800, our megawatt-class system, produces enough power to power about 3,000 households.”

CalWave’s device operates completely below the surface of the water, and as waves rise and fall, surge forward and backward, and the water moves in a circular motion, the device moves too. Dampers inside the device slow down that motion and convert it into torque, which drives a generator to produce electricity, a principle mirrored in some wind energy kite systems as they harvest aerodynamic forces.

“And so the waves move the system up and down. And every time it moves down, we can generate power, and then the waves bring it back up. And so that oscillating motion, we can turn into electricity just like a wind turbine,” said Lehmann.

Another approach is being piloted by Seattle-based Oscilla Power, which was awarded $1.8 million from the DOE, and is getting ready to deploy its wave energy converter off the coast of Hawaii, at the U.S. Navy Wave Energy Test site.

Oscilla Power’s device is composed of two parts. One part floats on the surface and moves with the waves in all directions — up and down, side to side and rotationally. This float is connected to a large, ring-shaped structure which hangs below the surface, and is designed to stay relatively steady, much like how underwater kites leverage a stable reference to generate power. The difference in motion between the float and the ring generates force on the connecting lines, which is used to rotate a gearbox to drive a generator.

″The system that we’re deploying in Hawaii is what we call the Triton-C. This is a community-scale system,” said Balky Nair, CEO of Oscilla Power. “It’s about a third of the size of our flagship product. It’s designed to be 100 kilowatt rated, and it’s designed for islands and small communities.”

Nair is excited by wave energy’s potential to generate electricity in remote regions, which currently rely on expensive and polluting diesel imports to meet their energy needs when other renewables aren’t available, and similar tidal energy for remote communities efforts in Canada point to viable models. Before wave energy is adopted at-scale, many believe we’ll see wave energy replacing diesel generators in off-the-grid communities.

A third company, C-Power, based in Charlottesville, Virginia, was awarded more than $4 million to test its grid-scale wave energy converter at PacWave. But first, the company wants to commercialize its smaller scale system, the SeaRAY, which is designed for lower-power applications. 

″Think about sensors in the ocean, research, metocean data gathering, maybe it’s monitoring or inspection,” said C-Power CEO Reenst Lesemann on the initial applications of his device.

The SeaRAY consists of two floats and a central body, the nacelle, which contains the drivetrain. As waves pass by, the floats bob up and down, rotating about the nacelle and turning their own respective gearboxes which power the electric generators.

Eventually, C-Power plans to scale up its SeaRAY so that it’s capable of satellite communications and deep water deployments, before building a larger system, called the StingRAY, for terrestrial electricity generation.

Meanwhile, one Swedish company, Eco Wave Power, is taking another approach completely, eschewing offshore technologies in favor of simpler wave power devices that can be installed on breakwaters, piers, and jetties.

“All the expensive conversion machinery, instead of being inside the floaters like in the competing technologies, is on land just like a regular power station. So basically this enables a very low installation, operation, and maintenance cost,” explained CEO Inna Braverman.

UK EV Per-Mile Taxes are reshaping road pricing and vehicle taxation for electric cars, raising fairness concerns, climate policy questions, and funding needs for infrastructure and charging networks across the country.

Key Points

They are per-mile road charges on EVs to fund infrastructure, raising fairness, emissions, and vehicle taxation concerns.

✅ Propose tax relief or credits for EV owners

✅ Consider emission-based road user charging

✅ Invest in charging networks and road infrastructure

As the UK continues its push towards a greener future with increased adoption of electric vehicles (EVs) and surging EV interest during supply disruptions, a growing number of electric car drivers are voicing their frustration over the current tax system. The debate centers around the per-mile vehicle taxes that are being proposed and implemented, which many argue are unfairly burdensome on EV owners. This issue has sparked a broader campaign advocating for a more equitable approach to vehicle taxation, one that reflects the evolving landscape of transportation and environmental policy.

Rising Costs for Electric Car Owners

Electric vehicles have been hailed as a crucial component in the UK’s strategy to reduce carbon emissions and combat climate change. Government incentives, such as grants for EV purchases and tax breaks, have been instrumental in encouraging the shift from petrol and diesel cars to cleaner alternatives, even as affordability concerns persist among many UK consumers. However, as the number of electric vehicles on the road grows, the financial dynamics of vehicle taxation are coming under scrutiny.

One of the key issues is the introduction and increase of per-mile vehicle taxes. While these taxes are designed to account for road usage and infrastructure costs, they have been met with resistance from EV drivers who argue that they are being disproportionately affected. Unlike traditional combustion engine vehicles, electric cars typically have lower running costs compared to petrol or diesel models and, in many cases, benefit from lower or zero emissions. Yet, the current tax system does not always reflect these advantages.

The Taxation Debate

The crux of the debate lies in how vehicle taxes are structured and implemented. Per-mile taxes are intended to ensure that all road users contribute fairly to the maintenance of transport infrastructure. However, the implementation of such taxes has raised concerns about fairness and affordability, particularly for those who have invested heavily in electric vehicles.

Critics argue that per-mile taxes do not adequately take into account the environmental benefits of driving an electric car, noting that the net impact depends on the electricity generation mix in each market. While EV owners are contributing to a cleaner environment by reducing emissions, they are also facing higher taxes that could undermine the financial benefits of their greener choice. This has led to calls for a reassessment of the tax system to ensure that it aligns with the UK’s climate goals and provides a fair deal for electric vehicle drivers.

Campaigns for Fairer Taxation

In response to these concerns, several advocacy groups and individual EV owners have launched campaigns calling for a more balanced approach to vehicle taxation. These campaigns emphasize the need for a system that supports the transition to electric vehicles and recognizes their role in reducing environmental impact, drawing on ambitious EV targets abroad as useful benchmarks.

Key proposals from these campaigns include:

1. Tax Relief for EV Owners: Advocates suggest providing targeted tax relief for electric vehicle owners to offset the costs of per-mile taxes. This could include subsidies or tax credits that acknowledge the environmental benefits of EVs and help to make up for higher road usage fees.

2. Emission-Based Taxation: An alternative approach is to design vehicle taxes based on emissions rather than mileage. This system would ensure that those driving high-emission vehicles contribute more to road maintenance, while EV owners, who are already reducing emissions, are not penalized.

3. Infrastructure Investments: Campaigners also call for increased investments in infrastructure that supports electric vehicles, such as charging networks and proper grid management practices that balance load. This would help to address concerns about the adequacy of current road maintenance and support the growing number of EVs on the road.

Government Response and Future Directions

The UK government faces the challenge of balancing revenue needs with environmental goals. While there is recognition of the need to update the tax system in light of increasing EV adoption, there is also a focus on ensuring that any changes are equitable and do not disincentivize the shift towards cleaner vehicles, while considering whether the UK grid can handle additional EV demand reliably.

Discussions are ongoing about how to best implement changes that address the concerns of electric vehicle owners while ensuring that the transportation infrastructure remains adequately funded. The outcome of these discussions will be critical in shaping the future of vehicle taxation in the UK and supporting the country’s broader environmental objectives.

Conclusion

As electric vehicle adoption continues to rise in the UK, the debate over vehicle taxation becomes increasingly important. The campaign for fairer per-mile taxes highlights the need for a tax system that supports the transition to cleaner transportation while also being fair to those who have made environmentally conscious choices. Balancing these factors will be key to achieving the UK’s climate goals and ensuring that all road users contribute equitably to the maintenance of transport infrastructure. The ongoing dialogue and policy adjustments will play a crucial role in shaping a sustainable and just future for transportation in the UK.

National Grid Cybersecurity Component Removal signals NCSC and GCHQ oversight of critical infrastructure, replacing NR Electric and Nari Technology grid control systems to mitigate supply chain risk, cyber threats, and blackout risk.

Key Points

A UK move to remove China-linked grid components after NCSC/GCHQ advice, reducing cyber and blackout risks.

✅ NCSC advice to remove NR Electric components

✅ GCHQ-linked review flags critical infrastructure risks

✅ Aims to cut blackout risk and supply chain exposure

Britain's National Grid has started removing components supplied by a unit of China-backed Nari Technology's from the electricity transmission network over cybersecurity fears, reflecting a wider push on protecting the power grid across critical sectors.

The decision came in April after the utility sought advice from the National Cyber Security Center (NCSC), a branch of the nation's signals intelligence agency, Government Communications Headquarters (GCHQ), amid campaigns like the Dragonfly campaign documented by Symantec, the newspaper quoted a Whitehall official as saying.

National Grid declined to comment citing "confidential contractual matters." "We take the security of our infrastructure very seriously and have effective controls in place to protect our employees and critical assets, while preparing for an independent operator transition in Great Britain, to ensure we can continue to reliably, safely and securely transmit electricity," it said in a statement.

The report said an employee at the Nari subsidiary, NR Electric Company-U.K., had said the company no longer had access to sites where the components were installed, at a time when utilities worldwide have faced control-room intrusions by state-linked hackers, and that National Grid did not disclose a reason for terminating the contracts.

It quoted another person it did not name as saying the decision was based on NR Electric Company-U.K.'s components that help control and balance the grid, respond to work-from-home demand shifts, and minimize the risk of blackouts.

It was unclear whether the components remained in the electricity transmission network, the report said, amid reports of U.S. power plant breaches that have heightened vigilance.

NR Electric Company-U.K., GCHQ and the Chinese Embassy in London did not immediately respond to requests for comment outside of business hours.

Britain's Department for Energy Security and Net Zero said that it did not comment on the individual business decisions taken by private organizations. "As a government department we work closely with the private sector to safeguard our national security, and to support efforts to fast-track grid connections across the network," it said in a statement.

UK Coal Phase-Out signals an energy transition, accelerating decarbonization with offshore wind, solar, and storage, advancing net-zero targets, cleaner air, and a just transition for communities impacted by fossil fuel decline.

Key Points

A policy to end coal power in the UK, boosting renewables and net-zero goals while improving air quality.

✅ Coal electricity fell from 40% in 2012 to under 3% by 2022

✅ Offshore wind and solar expand capacity; storage enhances reliability

✅ Just transition funds retrain workers and support coal regions

The United Kingdom is poised to mark a significant milestone in its energy history by phasing out coal power entirely, ending a reliance that has lasted for 142 years. This decision underscores the UK’s commitment to combating climate change and transitioning toward cleaner energy sources, reflecting a broader global energy transition away from fossil fuels. As the country embarks on this journey, it highlights both the achievements and challenges of moving towards a sustainable energy future.

A Historic Transition

The UK’s relationship with coal dates back to the Industrial Revolution, when coal was the backbone of its energy supply, driving factories, trains, and homes. However, as concerns over air quality and climate change have mounted, the nation has progressively shifted its focus toward renewable energy sources amid a global decline in coal-fired electricity worldwide. The decision to end coal power represents the culmination of this transformation, signaling a definitive break from a past heavily reliant on fossil fuels.

In recent years, the UK has made remarkable strides in reducing its carbon emissions. From 2012 to 2022, coal's contribution to the country's electricity generation plummeted from around 40% to less than 3%, as policies like the British carbon tax took effect across the power sector. This dramatic decline is largely due to the rise of renewable energy sources, such as wind, solar, and hydroelectric power, which have increasingly filled the gap left by coal.

Environmental and Health Benefits

The move away from coal power has significant environmental benefits. Coal is one of the most carbon-intensive energy sources, releasing substantial amounts of carbon dioxide (CO2) and other harmful pollutants into the atmosphere. By phasing out coal, the UK aims to significantly reduce its greenhouse gas emissions and improve air quality, which has been linked to serious health issues such as respiratory diseases and cardiovascular problems.

The UK government has set ambitious net zero policies, aiming to achieve net-zero carbon emissions by 2050. Ending coal power is a critical step in reaching this target, demonstrating leadership on the global stage and setting an example for other countries still dependent on fossil fuels. This transition not only addresses climate change but also promotes a healthier environment for future generations.

The Role of Renewable Energy

As the UK phases out coal, renewable energy sources are expected to play a central role in meeting the country's energy needs. Wind power, in particular, has surged in prominence, with the UK leading the world in offshore wind capacity. In 2020, wind energy surpassed coal for the first time, accounting for over 24% of the country's electricity generation.

Solar energy has also seen significant growth, contributing to the diversification of the UK’s energy mix. The government’s investments in renewable energy infrastructure and technology have facilitated this rapid transition, providing the necessary framework for a sustainable energy future.

Economic Implications

While the transition away from coal power presents environmental benefits, it also carries economic implications. The coal industry has historically provided jobs and economic activity, particularly in regions where coal mining was a mainstay, a dynamic echoed in analyses of the decarbonization of Canada's electricity grid and its regional impacts. As the UK moves toward a greener economy, there is an urgent need to support communities that may be adversely affected by this transition.

To address potential job losses, the government has emphasized the importance of investing in retraining programs and creating new opportunities in the renewable energy sector. This will be vital in ensuring a just transition that supports workers and communities as the energy landscape evolves.

Challenges Ahead

Despite the progress made, the journey toward a coal-free UK is not without challenges. One significant concern is the need for reliable energy storage solutions to complement intermittent renewable sources like wind and solar. Ensuring a stable energy supply during periods of low generation will be critical for maintaining grid reliability.

Moreover, public acceptance and engagement will be crucial, as illustrated by debates over New Zealand's electricity transition and its pace, as the UK navigates this transition. Engaging communities in discussions about energy policies and developments can foster understanding and support for the changes ahead.

Looking to the Future

The UK’s decision to phase out coal power after 142 years marks a significant turning point in its energy policy and environmental strategy. This historic shift not only aligns with the country’s climate goals but also showcases its commitment to a cleaner, more sustainable future.

As the UK continues to invest in renewable energy and transition away from fossil fuels, it sets an important example for other nations, including those on China's path to carbon neutrality, grappling with similar challenges. By embracing this transition, the UK is not only addressing pressing environmental concerns but also paving the way for a greener economy that can thrive in the decades to come.

Global Renewable LCOE Trends reveal offshore wind costs down 32%, with 10MW turbines, lower CAPEX and OPEX, and parity for solar PV and onshore wind in Europe, China, and California, per BloombergNEF analysis.

Key Points

Benchmarks showing falling LCOE for offshore wind, onshore wind, and solar PV, driven by larger turbines and lower CAPEX

✅ Offshore wind LCOE $78/MWh; $53-64/MWh in DK/NL excl. transmission

✅ Onshore wind $47/MWh; solar PV $51/MWh, best $26-36/MWh

✅ Cost drivers: 10MW turbines, lower CAPEX/OPEX, weak China demand

World offshore wind costs have fallen 32% from just a year ago and 12% compared with the first half of 2019, according to a BNEF long-term outlook from BloombergNEF.

In its latest Levelized Cost of Electricity (LCOE) Update, BloombergNEF said its current global benchmark LCOE estimate for offshore wind is $78 a megawatt-hour.

“New offshore wind projects throughout Europe, including the UK's build-out, now deploy turbines with power ratings up to 10MW, unlocking CAPEX and OPEX savings,” BloombergNEF said.

In Denmark and the Netherlands, it expects the most recent projects financed to achieve $53-64/MWh excluding transmission.

New solar and onshore wind projects have reached parity with average wholesale power prices in California and parts of Europe, while in China levelised costs are below the benchmark average regulated coal price, according to BloombergNEF.

The company's global benchmark levelized cost figures for onshore wind and PV projects financed in the last six months are at $47 and $51 a megawatt-hours, underscoring that renewables are now the cheapest new electricity option in many regions, down 6% and 11% respectively compared with the first half of 2019.

BloombergNEF said for wind this is mainly down to a fall in the price of turbines – 7% lower on average globally compared with the end of 2018.

In China, the world’s largest solar market, the CAPEX of utility-scale PV plants has dropped 11% in the last six months, reaching $0.57m per MW.

“Weak demand for new plants in China has left developers and engineering, procurement and construction firms eager for business, and this has put pressure on CAPEX,” BloombergNEF said.

It added that estimates of the cheapest PV projects financed recently – in India, Chile and Australia – will be able to achieve an LCOE of $27-36/MWh, assuming competitive returns for their equity investors.

Best-in-class onshore wind farms in Brazil, India, Mexico and Texas can reach levelized costs as low as $26-31/MWh already, the research said.

Programs such as the World Bank wind program are helping developing countries accelerate wind deployment as costs continue to drop.

BloombergNEF associate in the energy economics team Tifenn Brandily said: “This is a three- stage process. In phase one, new solar and wind get cheaper than new gas and coal plants on a cost-of- energy basis.

“In phase two, renewables reach parity with power prices. In phase three, they become even cheaper than running existing thermal plants.

“Our analysis shows that phase one has now been reached for two-thirds of the global population.

“Phase two started with California, China and parts of Europe. We expect phase three to be reached on a global scale by 2030.

“As this all plays out, thermal power plants will increasingly be relegated to a balancing role, looking for opportunities to generate when the sun doesn’t shine or the wind doesn’t blow.”

Offshore Wind Cost Competitiveness is rising as larger turbines boost megawatt output, cut LCOE, and trim maintenance and installation time, enabling projects in New England to rival natural gas pricing while scaling reliably.

Key Points

It describes how larger offshore turbines lower LCOE and O&M, making U.S. projects price competitive with natural gas.

✅ Larger turbines boost MW output and reduce LCOE.

✅ Lower O&M and faster installation cut lifecycle costs.

✅ Competes with gas in New England bids, per BNEF.

Massive offshore wind turbines keep getting bigger, as projects like the biggest UK offshore wind farm come online, and that’s helping make the power cheaper — to the point where developers say new projects in U.S. waters can compete with natural gas.

The price “is going to be a real eye-opener,” said Bryan Martin, chairman of Deepwater Wind LLC, which won an auction in May to build a 400-megawatt wind farm southeast of Rhode Island.

Deepwater built the only U.S. offshore wind farm, a 30-megawatt project that was completed south of Block Island in 2016. The company’s bid was selected by Rhode Island the same day that Massachusetts picked Vineyard Wind to build an 800-megawatt wind farm in the same area, while international investors such as Japanese utilities in UK projects signal growing confidence.

Bigger turbines that make more electricity have cut the cost per megawatt by about half, a trend aided by higher-than-expected wind potential in many markets, said Tom Harries, a wind analyst at Bloomberg New Energy Finance. That also reduces maintenance expenses and installation time. All of this is helping offshore wind vie with conventional power plants.

“You could not build a thermal gas plant in New England for the price of the wind bids in Massachusetts and Rhode Island,” Martin said Friday at the U.S. Offshore Wind Conference in Boston. “It’s very cost-effective for consumers.”

The Massachusetts project could be about $100 to $120 a megawatt hour, according to a February estimate from Harries, though recent UK price spikes during low wind highlight volatility. The actual prices there and in Rhode Island weren’t disclosed.

For comparison, a new U.S. combine-cycle gas turbine ranges from $40 to $60 a megawatt-hour, and a new coal plant is $67 to $113, according to BNEF data.

A new power plant in land-constrained New England would probably be higher than that, and during winter peaks the region has seen record oil-fired generation in New England that underscores reliability concerns. More importantly, gas plants get a significant portion of their revenue from being able to guarantee that power is always available, something wind farms can’t do, said William Nelson, a New York-based analyst with BNEF. Looking only at the price at which offshore turbines can deliver electricity is a “narrow mindset,” he said.
