Hydro One and Redline team up on grid modernization

Energy Vault Gravity Storage uses crane-stacked concrete blocks to deliver long-duration, grid-scale renewable energy; a SoftBank Vision Fund-backed, pumped-hydro analog enabling baseload power and a lithium-ion alternative with proprietary control algorithms.

Key Points

Gravity-based cranes stack blocks to store and dispatch power for hours, enabling grid-scale, low-cost storage.

✅ 4 MW/35 MWh modules; ~9-hour duration

✅ Estimated $200-$250/kWh; lower LCOE than lithium-ion

✅ Backed by SoftBank Vision Fund; Cemex and Tata support

Energy Vault, the Swiss-U.S. startup that says it can store and discharge electrical energy through a super-sized concrete-and-steel version of a child’s erector set, has landed a $110 million investment from Japan’s SoftBank Vision Fund to take its technology to commercial scale.

Energy Vault, a spinout of Pasadena-based incubator Idealab and co-founded by Idealab CEO and billionaire investor Bill Gross, unstealthed in November with its novel approach to using gravity to store energy.

Simply put, Energy Vault plans to build storage plants — dubbed “Evies” — consisting of a 35-story crane with six arms, surrounded by a tower consisting of thousands of concrete bricks, each weighing about 35 tons.

This plant will “store” energy by using electricity to run the cranes that lift bricks from the ground and stack them atop of the tower, and “discharge” energy by reversing that process. It’s a mechanical twist on the world’s most common energy storage technology, pumped hydro, which “stores” energy by pumping water uphill, and lets it fall to spin turbines when electricity is needed, even as California funds 100-hour long-duration storage pilots to expand flexibility worldwide.

But behind this simplicity lies some heavy-duty software to orchestrate the cranes and blocks, with a "unique stack of proprietary algorithms" to balance energy supply and demand, volatility, grid stability, weather elements and other variables.

CEO and co-founder Robert Piconi said in a November interview with GTM that the standard array would deliver 4 megawatts/35 megawatt-hours of storage, which translates to nearly 9 hours of duration — the equivalent of building the tower to its height, and then reducing it to ground level. It can be built on-site in partnership with crane manufacturers and recycled concrete material, and can run fully automated for decades with little deterioration, he said.

And the cost, which Piconi pegged in the $200 to $250 per kilowatt-hour range, with room to decline further, is roughly 50 percent below the upfront price of the conventional storage market today, and 80 percent below it on levelized cost, he said, a trend utilities see benefits in as they plan resources.

The result, according to Wednesday’s statement, is a technology that could allow “renewables to deliver baseload power for less than the cost of fossil fuels 24 hours a day,” in applications such as community microgrids serving low-income housing.

Wednesday’s announcement builds on a recent investment from Mexico's Cemex Ventures, the corporate venture capital unit of building materials giant Cemex, along with a promise of deployment support from Cemex's strategic network, and also follows project financing for a California green hydrogen microgrid led by the company. Piconi said in November that the company had sufficient investment from two funding rounds to carry it through initial customer deployments, though he declined to disclose figures.

This is the first energy storage investment for Vision Fund, the $100 billion venture fund set up by SoftBank founder Masayoshi Son. While large by startup standards, it’s in keeping with the capital costs that Energy Vault will face in scaling up its technology to meet its commitments, amid mounting demand in regions like Ontario energy storage that face supply crunches. Those include a 35 megawatt-hour order with Tata Power Company, the energy-producing arm of the Indian industrial conglomerate, first unveiled in November, as well as plans to demonstrate its first storage tower in northern Italy in 2019.

For Vision Fund, it’s also an unusual choice for a storage investment, given that the vast majority of venture capital in the industry today is being directed toward lithium-ion batteries, and even Mercedes-Benz energy storage ventures targeting the U.S. market. Lithium-ion batteries are limited in terms of how many hours they can provide cost-effectively, with about 4 hours being seen as the limit today.

The search for long-duration energy storage has driven investment into flow battery technologies such as grid-scale vanadium systems deployed on utility networks, compressed-air energy storage and variations on gravity-based storage, including a previous startup backed by Gross and Idealab, Energy Cache, whose idea of using a ski lift carrying buckets of gravel up a hill to store energy petered out with a 50-kilowatt pilot project.

IAEA OSART Cernavoda highlights strengthened operational safety at Romania’s Cernavoda NPP, citing improved maintenance practices, simulator training, and deficiency reporting, with ongoing actions on spare parts procurement, procedure updates, and chemical control for nuclear compliance.

Key Points

An IAEA follow-up mission confirming improved operational safety at Cernavoda NPP, with remaining actions tracked.

✅ Enhanced simulator training and crew performance

✅ Improved field deficiency identification and reporting

✅ Ongoing upgrades to procedures, spares, and chemical control

The International Atomic Energy Agency (IAEA) said yesterday that the operator of Romania’s Cernavoda nuclear power plant had demonstrated "strengthened operational safety" by addressing the findings of an initial IAEA review in 2016. The Operational Safety Review Team (OSART) concluded a five-day follow-up mission on 8 March to the Cernavoda plant, which is on the Danube-Black Sea Canal, about 160 km from Bucharest.

The plant's two 706 MWe CANDU pressurised heavy water reactors, reflecting Canadian nuclear projects, came online in 1996 and 2007, respectively.

The OSART team was led by Fuming Jiang, a senior nuclear safety officer at the IAEA, which recently commended China's nuclear security in separate assessments.

"We saw improvements in key areas, such as the procurement of important spare parts, the identification and reporting of some deficiencies, and some maintenance work practices, as evidenced by relevant performance indicators," Jiang said, noting milestones at nuclear projects worldwide this year.

The team observed that several findings from the 2016 review had been fully addressed, including: enhanced operator crew performance during simulator training; better identification and reporting of deficiencies in the field; and improvement in maintenance work practices.

More time is required, it said, to fully implement some actions, including: further improvements in the procurement of important spare parts with relevance to safety; further enhancement in the revision and update of some operating procedures, drawing on lessons from Pickering NGS life extensions undertaken in Ontario; and control and labelling of some plant chemicals.

Dan Bigu, site vice president of Cernavoda NPP, said the 2016 mission had "proven to be very beneficial", adding that the current follow-up mission would "provide further catalyst support to our journey to nuclear excellence".

The team provided a draft report of the mission to the plant's management and a final report will be submitted to the Romanian government, which recently moved to terminate talks with a Chinese partner on a separate nuclear project, within three months.

OSART missions aim to improve operational safety by objectively assessing safety performance, even as the agency reports mines at Ukraine's Zaporizhzhia plant amid ongoing risks, using the IAEA's safety standards and proposing recommendations and suggestions for improvement where appropriate. The follow-up missions are standard components of the OSART programme and, as the IAEA has warned of risks from attacks on Ukraine's power grids, are typically conducted within two years of the initial mission.

California Biofuels vs EV Subsidies examines tradeoffs in decarbonization, greenhouse gas reductions, clean energy deployment, charging infrastructure, energy security, lifecycle emissions, and transportation sector policy to meet climate goals and accelerate sustainable mobility.

Key Points

Policy tradeoffs weighing biofuels and EVs to cut GHGs, boost energy security, and advance clean transportation.

✅ Near-term blending cuts emissions from existing fleets

✅ EVs scale with a cleaner grid and charging buildout

✅ Lifecycle impacts and costs guide optimal subsidy mix

California is at the forefront of the transition to a greener economy, driven by its ambitious goals to reduce greenhouse gas emissions and combat climate change. As part of its strategy, the state is grappling with the question of whether it should subsidize out-of-state biofuels or in-state electric vehicles (EVs) to meet these goals. Both options come with their own sets of benefits and challenges, and the decision carries significant implications for the state’s environmental, economic, and energy landscapes.

The Case for Biofuels

Biofuels have long been promoted as a cleaner alternative to traditional fossil fuels like gasoline and diesel. They are made from organic materials such as agricultural crops, algae, and waste, which means they can potentially reduce carbon emissions in comparison to petroleum-based fuels. In the context of California, biofuels—particularly ethanol and biodiesel—are viewed as a way to decarbonize the transportation sector, which is one of the state’s largest sources of greenhouse gas emissions.

Subsidizing out-of-state biofuels can help California reduce its reliance on imported oil while promoting the development of biofuel industries in other states. This approach may have immediate benefits, as biofuels are widely available and can be blended with conventional fuels to lower carbon emissions right away. It also allows the state to diversify its energy sources, improving energy security by reducing dependency on oil imports.

Moreover, biofuels can be produced in many regions across the United States, including rural areas. By subsidizing out-of-state biofuels, California could foster economic development in these regions, creating jobs and stimulating agricultural innovation. This approach could also support farmers who grow the feedstock for biofuel production, boosting the agricultural economy in the U.S.

However, there are drawbacks. The environmental benefits of biofuels are often debated. Critics argue that the production of biofuels—particularly those made from food crops like corn—can contribute to deforestation, water pollution, and increased food prices. Additionally, biofuels are not a silver bullet in the fight against climate change, as their production and combustion still release greenhouse gases. When considering whether to subsidize biofuels, California must also account for the full lifecycle emissions associated with their production and use.

The Case for Electric Vehicles

In contrast to biofuels, electric vehicles (EVs) offer a more direct pathway to reducing emissions from transportation. EVs are powered by electricity, and when coupled with renewable energy sources like solar or wind power, they can provide a nearly zero-emission solution for personal and commercial transportation. California has already invested heavily in EV infrastructure, including expanding its network of charging stations and exploring how EVs can support grid stability through vehicle-to-grid approaches, and offering incentives for consumers to purchase EVs.

Subsidizing in-state EVs could stimulate job creation and innovation within California's thriving clean-tech industry, with other states such as New Mexico projecting substantial economic gains from transportation electrification, and the state has already become a hub for electric vehicle manufacturers, including Tesla, Rivian, and several battery manufacturers. Supporting the EV industry could further strengthen California’s position as a global leader in green technology, attracting investment and fostering growth in related sectors such as battery manufacturing, renewable energy, and smart grid technology.

Additionally, the environmental benefits of EVs are substantial. As the electric grid becomes cleaner with an increasing share of renewable energy, EVs will become even greener, with lower lifecycle emissions than biofuels. By prioritizing EVs, California could further reduce its carbon footprint while also achieving its long-term climate goals, including reaching carbon neutrality by 2045.

However, there are challenges. EV adoption in California remains a significant undertaking, requiring major investments in infrastructure as they challenge state power grids in the near term, technology, and consumer incentives. The cost of EVs, although decreasing, still remains a barrier for many consumers. Additionally, there are concerns about the environmental impact of lithium mining, which is essential for EV batteries. While renewable energy is expanding, California’s grid is still reliant on fossil fuels to some degree, and in other jurisdictions such as Canada's 2019 electricity mix fossil generation remains significant, meaning that the full emissions benefit of EVs is not realized until the grid is entirely powered by clean energy.

A Balancing Act

The debate between subsidizing out-of-state biofuels and in-state electric vehicles is ultimately a question of how best to allocate California’s resources to meet its climate and economic goals. Biofuels may offer a quicker fix for reducing emissions from existing vehicles, but their long-term benefits are more limited compared to the transformative potential of electric vehicles, even as some analysts warn of policy pitfalls that could complicate the transition.

However, biofuels still have a role to play in decarbonizing hard-to-abate sectors like aviation and heavy-duty transportation, where electrification may not be as feasible in the near future. Thus, a mixed strategy that includes both subsidies for EVs and biofuels may be the most effective approach.

Ultimately, California’s decision will likely depend on a combination of factors, including technological advancements, 2021 electricity lessons, and the pace of renewable energy deployment, and the state’s ability to balance short-term needs with long-term environmental goals. The road ahead is not easy, but California's leadership in clean energy will be crucial in shaping the nation’s response to climate change.

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.

Greengen Misfeasance Ruling details a B.C. Supreme Court decision awarding $10.125 million over wrongfully denied Crown land and water licence permits for a Fries Creek run-of-river hydro project under a BC Hydro contract.

Key Points

A B.C. Supreme Court ruling awarding $10.125M for wrongful denial of Crown land and water licences on Greengen's project.

✅ $10.125M damages for misfeasance in public office

✅ Denial of Crown land tenure and water licence permits

✅ Tied to Fries Creek run-of-river and BC Hydro EPA

A B.C. Supreme Court judge has ordered the provincial government to pay $10.125 million after it denied permits to a company that wanted to build a run-of-the river independent power project near Squamish.

In his Oct. 10 decision, Justice Kevin Loo said the plaintiff, Greengen Holdings Ltd., “lost an opportunity to achieve a completed and profitable hydro-electric project” after government representatives wrongfully exercised their legal authority, a transgression described in the ruling as “misfeasance,” with separate concerns reflected in an Ontario market gaming investigation reported elsewhere.

Between 2003 and 2009, the company sought to develop a hydro-electric project on and around Fries Creek, which sits opposite the Brackendale neighbourhood on the other side of the Squamish River. To do so, Greengen Holdings Ltd. required a water licence from the Minister of the Environment and tenure over Crown land from the Minister of Agriculture.

After a lengthy process involving extensive communications between Greengen and various provincial and other ministries and regulatory agencies, the permits were denied, according to Loo. Both decisions cited impacts on Squamish Nation cultural sites that could not be mitigated.

Elsewhere, an Indigenous-owned project in James Bay proceeded despite repeated denials, underscoring varied approaches to community participation.

40-year electricity plan relied on Crown land
The case dates back to December 2005, when BC Hydro issued an open call for power with Greengen. The company submitted a tender several months later.

On July 26, 2006, BC Hydro awarded Greengen an energy purchase agreement, amid evolving LNG electricity demand across the province, under which Greengen would be entitled to supply electricity at a fixed price for 40 years.

Unlike conventional hydroelectric projects, such as new BC generating stations recently commissioned, which store large volumes of water in reservoirs, and in so doing flood large tracts of land, a run of the river project often requires little or no water storage. Instead, from a high elevation, they divert water from a stream or river channel.

Water is then sent into a pressured pipeline known as a penstock, and later passed through turbines to generate electricity, Loo explained, as utilities pursue long-term plans like the Hydro-Québec strategy to reduce fossil fuel reliance. The system returns water to the original stream or river, or into another body of water. 

The project called for most of that infrastructure to be built on Crown land, according to the ruling.

All sides seemed to support the project
In early 2005, company principle Terry Sonderhoff discussed the Fries Creek project in a preliminary meeting with Squamish Nation Chief Ian Campbell.

“Mr. Sonderhoff testified that Chief Campbell seemed supportive of the project at the time,” Loo said.

Climate Change Consensus and Disinformation highlights the 97% peer-reviewed agreement on human-caused warming, IPCC warnings, and how fossil fuel lobbying, misinformation, and astroturf tactics echo tobacco denial to mislead media and voters.

Key Points

Explains the 97% scientific consensus and the disinformation that obscures IPCC findings and misleads the public.

✅ 97% peer-reviewed consensus on human-caused climate change

✅ Fossil fuel funding drives denial and media misinformation

✅ IPCC and major scientific bodies confirm severe impacts

Orson Johnson says there is no scientific consensus on climate change. He’s wrong. A 2015 study by Drexel University’s Robert Brulle found that nearly $1 billion per year is being spent to support climate change denial. Electric utilities, fossil fuel and transportation sectors outspent environmental and renewable energy sectors by more than 10-to-1, undermining efforts to achieve net-zero electricity emissions globally. It is virtually the same strategy that tobacco companies used to deny the dangers of tobacco smoke, spending hundreds of millions of dollars to delay recognition of harm from tobacco smoke for decades, and today Trump's oil policies can similarly influence Wall Street's energy strategy. These are the same debunked sources Johnson quotes in his commentary.

The authors of six independent peer-reviewed papers on the consensus for human-caused climate change examined “the available studies and conclude that the finding of 97% consensus in published climate research is robust and consistent with other surveys of climate scientists and peer-reviewed studies,” according to an abstract in Environmental Research Letters, and public support for action is strong, with most Americans willing to contribute financially to climate solutions. Of the 30,000 scientists (people with a bachelor’s degree or higher in science) Johnson cites, only 39 specialized in climate science.

A new study by the U.N. Intergovernmental Panel on Climate Change draws on momentum from the Katowice climate summit to warn that “The consequences for nature and humanity are sweeping and severe.”

California’s Office of Planning and Research says: “Every major scientific organization in the United States with relevant expertise has confirmed the IPCC’s conclusion, including the National Academy of Sciences, the American Meteorological Society, the American Geophysical Union, and the American Association for the Advancement of Science. The list of international scientific organizations affirming the worldwide consensus on climate change is even longer.”

Former President Obama argued that decarbonization is irreversible as the clean-energy transition accelerates.

This issue is a symptom of an even larger problem. Recently, Facebook announced it would continue to allow political ads that contain obvious lies. America’s corporate news media has been following the same policy for years. Printing stories and commentary with information that is clearly not true or where data has been cherry-picked to strongly imply a lie, such as claims that Ottawa is making electricity more expensive for Albertans, sets up a false equivalence fallacy in which two incompatible arguments appear to be logically equivalent when, in fact, they are not.

Conservatives focus exclusively on progressive income taxes to argue that rich people pay a disproportionate share of taxes while ignoring that they take a disproportionate share of income, and federal income taxes account for less than half of taxes collected, with almost all of the other taxes being heavily regressive. Critics of single-payer healthcare disregard that almost every other developed country on earth has been using single-payer for decades to provide better care with universal coverage at roughly half the cost. Other examples abound, including recent policy milestones like the historic U.S. climate deal that nevertheless become targets of misinformation. We live in a society where truth is no longer truth, reality is supplanted by alternative facts and where crippling polarization is driven by the inability to agree on basic facts.
