Ontario Launches Hydrogen Innovation Fund

Space-Based Solar Power enables wireless energy transfer from orbital solar arrays, using microwave beaming to rectennas on Earth, delivering clean baseload power beyond weather and night limits, as demonstrated by Caltech and NASA.

Key Points

Space-based solar power beams microwaves from arrays to rectennas, delivering clean electricity beyond weather and night.

✅ Caltech demo proved wireless power transfer in space.

✅ Microwaves beam to rectennas for grid-scale clean energy.

✅ Operates above clouds, enabling continuous baseload supply.

Ali Hajimiri thinks there’s a better way to power the planet — one that’s not getting the attention it deserves. The Caltech professor of electrical engineering envisages thousands of solar panels floating in space, unobstructed by clouds and unhindered by day-night cycles, effectively generating electricity from the night sky for continuous delivery, wirelessly transmitting massive amounts of energy to receivers on Earth.

This year, that vision moved closer to reality when Mr. Hajimiri, together with a team of Caltech researchers, proved that wireless power transfer in space was possible: Solar panels they had attached to a Caltech prototype in space successfully converted electricity into microwaves and beamed those microwaves to receivers, as a demonstration of beaming power from space to devices about a foot away, lighting up two LEDs.

The prototype also beamed a tiny but detectable amount of energy to a receiver on top of their lab’s building in Pasadena, Calif. The demonstration marks a first step in the wireless transfer of usable power from space to Earth, and advances in low-cost solar batteries could help store and smooth that power flow — a power source that Mr. Hajimiri believes will be safer than direct sun rays. “The beam intensity is to be kept less than solar intensity on earth,” he said.

Finding alternative energy sources is one of the topics that will be discussed by leaders in business, science and public policy, including wave energy, during The New York Times Climate Forward event on Thursday. The Caltech demonstration was a significant moment in the quest to realize space-based solar power, amid policy moves such as a proposed tenfold increase in U.S. solar that would remake the U.S. electricity system — a clean energy technology that has long been overshadowed by other long-shot clean energy ideas, such as nuclear fusion and low-cost clean hydrogen.

If space-based solar can be made to work on a commercial scale, said Nikolai Joseph, a NASA Goddard Space Flight Center senior technology analyst, and integrate with peer-to-peer energy sharing networks, such stations could contribute as much as 10 percent of global power by 2050.

The idea of space-based solar energy has been around since at least 1941, when the science-fiction writer Isaac Asimov set one of his short stories, “Reason,” on a solar station that beamed energy by microwaves to Earth and other planets.

In the 1970s, when a fivefold increase in oil prices sparked interest in alternative energy, NASA and the Department of Energy conducted the first significant study on the topic. In 1995, under the direction of the physicist John C. Mankins, NASA took another look and concluded that investments in space-launch technology were needed to lower the cost and move closer to cheap abundant electricity before space-based solar power could be realized.

“There was never any doubt about it being technically feasible,” said Mr. Mankins, now president of Artemis Innovation Management Solutions, a technology consulting group. “The cost was too prohibitive.”

Volvo Electric Heavy-Duty Trucks lead Europe’s e-mobility shift, meeting strict emissions rules with battery-electric drivelines, hydrogen fuel cell roadmaps, fast charging infrastructure, and autonomous freight solutions for regional haulage and urban construction.

Key Points

A battery-electric heavy truck range for haulage and urban construction, targeting zero emissions and compliance.

✅ Up to 44t GCW, ranges up to 300 km per charge

✅ Battery-electric now; hydrogen fuel cells targeted next

✅ Production from 2022; suited to haulage and construction

According to the report published by Allied Market Research, the global electric truck market generated $422.5M (approx €355.1M) in 2019 and is estimated to reach $1.89B (approx €1.58B) by 2027, registering a CAGR of 25.8% from 2020 to 2027, reflecting broader expectations that EV adoption within a decade will accelerate worldwide. 

The surge in government initiatives to promote e-mobility and stringent emission norms on vehicles using fossil fuels (petrol and diesel) is driving the growth of the global electric truck market, while shifts in the EV aftermarket are expected to reinforce this trend. 

Launching a range of electric trucks in 2021
Volvo is among the several companies, including early moves like Tesla's truck reveal efforts, trying to cash in on this popular and lucrative market. Recently, the company announced that it’s going to launch a complete heavy-duty range of trucks with electric drivelines starting in Europe in 2021. Next year, hauliers in Europe will be able to order all-electric versions of Volvo’s heavy-duty trucks. The sales will begin next year and volume production will start in 2022. 

“To reduce the impact of transport on the climate, we need to make a swift transition from fossil fuels to alternatives such as electricity. But the conditions for making this shift, and consequently the pace of the transition, vary dramatically across different hauliers and markets, depending on many variables such as financial incentives, access to charging infrastructure and type of transport operations,” explains Roger Alm, President Volvo Trucks.

Used for regional transport and urban construction operations
According to the company, it is now testing electric heavy-duty models – Volvo FH, FM, and FMX trucks, which will be used for regional transport and urban construction operations in Europe, and in the U.S., 70 Volvo VNR Electric trucks are being deployed in California initiatives as well. These Volvo trucks will offer a complete heavy-duty range with electric drivelines. These trucks will have a gross combination weight of up to 44 tonnes.

“Our chassis is designed to be independent of the driveline used. Our customers can choose to buy several Volvo trucks of the same model, with the only difference being that some are electric and others are powered by gas or diesel. As regards product characteristics, such as the driver’s environment, reliability, and safety, all our vehicles meet the same high standards. Drivers should feel familiar with their vehicles and be able to operate them safely and efficiently regardless of the fuel used,” says Alm.

Fossil free by 2040
Depending on the battery configuration the range could be up to 300 km, claims the company. Back in 2019, Volvo started manufacturing the Volvo FL Electric and FE Electric for city distribution and refuse operations, primarily in Europe, while in the van segment, Ford's all-electric Transit targets similar urban use cases. Volvo Trucks aims to start selling electric trucks powered by hydrogen fuel cells in the second half of this decade. Volvo Trucks’ objective is for its entire product range to be fossil-free by 2040.

Back in 2019, Swedish autonomous and electric freight mobility leader provider Einride’s Pod became the world’s first autonomous, all-electric truck to operate a commercial flow for DB Schenker with a permit on the public road. Last month, the company launched its next-generation Pod in the hopes to have it on the road starting from 2021, while major fleet commitments such as UPS's Tesla Semi pre-orders signal broader demand.

China Compressed-Air Energy Storage enables grid flexibility using salt caverns in Jiangsu, delivering long-duration storage for wind and solar, 60 MW capacity, dispatchable power, and low-cost, safe, round-the-clock clean energy integration.

Key Points

Stores off-peak power by compressing air in salt caverns, then drives turbines on demand to balance renewables.

✅ 60 MW Jintan plant connects to grid; commercial CAES milestone

✅ Uses salt caverns; low-cost long-duration storage; high safety

✅ Balances wind and solar; improves grid flexibility and reliability

China is set to connect its first commercial compressed-air energy storage plant to the grid as it seeks more ways to harness fast-growing clean power resources, including new hydropower alongside other long-duration options such as gravity power technologies for around-the-clock use.

China Huaneng Group Co. said its Jiangsu Jintan Salt Cave project recently underwent four days of successful trials and is now ready for commercial operations. The 60-megawatt plant will be the largest compressed air energy storage plant built anywhere in the world since 1991, and the first in China outside of small-scale technology demonstration projects, as China's electricity demand patterns remain in flux, according to BloombergNEF.

The plant will use electricity at night when demand is low to pump air into an underground salt cavern. Then, when demand is high during the day, it can release the compressed air at high enough pressure to spin a turbine and produce electricity, aligning with projections that 60% electricity by 2060 could be reached according to industry outlooks.

Underground compressed air is considered one of the least costly forms of long-term energy storage and has low safety concerns, according to BloombergNEF. But its reliance on certain topographical features such as underground caverns may limit wider deployment, a challenge shared by other regions weighing large-scale storage options for reliability. It’s gained a foothold in China, with nearly four gigawatts of projects in the pipeline, while there are less than two gigawatts combined planned in the rest of the world. Shandong province said just this week in this year's work plan that it would build three projects using the technology.

The Jintan salt caves in Jiangsu, China’s second-biggest provincial economy just north of Shanghai, can store about 10 million cubic meters of gas, enough to power four gigawatts of compressed air plants, according to a Science and Technology Daily report from last year. 

Energy storage is a key part of China’s plan to build a larger and more flexible grid as it tries to peak carbon emissions before 2030 and zero them out before 2060, alongside continued nuclear energy development to stabilize baseload supply. The country is adding a world-leading amount of wind and solar power every year, but their intermittency strains grids that need to be able to deliver electricity all the time, spurring interest in green hydrogen as a flexible complement. China has set targets of 30 gigawatts of new-energy storage by 2025 and 120 gigawatts of pumped hydro storage by 2030.

CAISO Renewable Curtailments reflect grid balancing under transmission congestion and oversupply, reducing solar and wind output while leveraging WEIM trading, battery storage, and transmission expansion to integrate renewables and stabilize demand-supply.

Key Points

CAISO renewable curtailments are reductions in wind and solar output to balance grid amid congestion or oversupply.

✅ Driven mainly by transmission congestion, less by oversupply.

✅ Peaks in spring when demand is low and solar output is high.

✅ Mitigated by WEIM trades, new lines, and battery storage growth.

The California Independent System Operator (CAISO), the grid operator for most of the state, is increasingly curtailing solar- and wind-powered electricity generation, as reported in rising curtailments, as it balances supply and demand during the rapid growth of wind and solar power in California.

Grid operators must balance supply and demand to maintain a stable electric system as advances in solar and wind continue to scale. The output of wind and solar generators are reduced either through price signals or rarely, through an order to reduce output, during periods of:

Congestion, when power lines don’t have enough capacity to deliver available energy
Oversupply, when generation exceeds customer electricity demand

In CAISO, curtailment is largely a result of congestion. Congestion-related curtailments have increased significantly since 2019 because California's solar boom has been outpacing upgrades in transmission capacity.

In 2022, CAISO curtailed 2.4 million megawatthours (MWh) of utility-scale wind and solar output, a 63% increase from the amount of electricity curtailed in 2021. As of September, CAISO has curtailed more than 2.3 million MWh of wind and solar output so far this year, even as the US project pipeline is dominated by wind, solar, and batteries.

Solar accounts for almost all of the energy curtailed in CAISO—95% in 2022 and 94% in the first seven months of 2023. CAISO tends to curtail the most solar in the spring when electricity demand is relatively low (because moderate spring temperatures mean less demand for space heating or air conditioning) and solar output is relatively high, although wildfire smoke impacts can reduce available generation during fire season as well.

CAISO has increasingly curtailed renewable generation as renewable capacity has grown in California, and the state has even experienced a near-100% renewables moment on the grid in recent years. In 2014, a combined 9.0 gigawatts (GW) of wind and solar capacity had been built in California. As of July 2023, that number had grown to 17.6 GW. Developers plan to add another 3.0 GW by the end of 2024.

CAISO is exploring and implementing various solutions to its increasing curtailment of renewables, including:

The Western Energy Imbalance Market (WEIM) is a real-time market that allows participants outside of CAISO to buy and sell energy to balance demand and supply. In 2022, more than 10% of total possible curtailments were avoided by trading within the WEIM. A day ahead market is expected to be operational in Spring 2025.

CAISO is expanding transmission capacity to reduce congestion. CAISO’s 2022–23 Transmission Planning Process includes 45 transmission projects to accommodate load growth and a larger share of generation from renewable energy sources.

CAISO is promoting the development of flexible resources that can quickly respond to sudden increases and decreases in demand such as battery storage technologies that are rapidly becoming more affordable. California has 4.9 GW of battery storage, and developers plan to add another 7.6 GW by the end of 2024, according to our survey of recent and planned capacity changes. Renewable generators can charge these batteries with electricity that would otherwise have been curtailed.

Electric Fleet Grid Planning aligns utilities, charging infrastructure, distribution upgrades, and substation capacity to meet megawatt loads from medium- and heavy-duty EV trucks and buses, enabling managed charging, storage, and corridor fast charging.

Key Points

A utility plan to upgrade feeders and substations for EV fleets, coordinating charging, storage, and load management.

✅ Plans distribution, substation, and transformer upgrades

✅ Supports managed charging and on-site storage

✅ Aligns utility investment with fleet adoption timelines

As more electric buses and trucks enter the market, future fleets will require a lot of electricity for charging and will challenge state power grids over time. While some utilities in California and elsewhere are planning for an increase in power demand, many have yet to do so and need to get started.

This issue is critical, because freight trucks emit more than one-quarter of all vehicle emissions. Recent product developments offer growing opportunities to electrify trucks and buses and slash their emissions (see our recent white paper). And just last week, a group of 15 states plus D.C. announced plans to fully electrify truck sales by 2050. Utilities will need to be ready to power electric fleets.

Electric truck fleets need substantial power
Power for trucks and buses is generally more of an issue than for cars because trucks typically have larger batteries and because trucks and buses are often parts of fleets with many vehicles that charge at the same location. For example, a Tesla Model 3 battery stores 54-75 kWh; a Proterra transit bus battery stores 220-660 kWh. In Amsterdam, a 100-bus transit fleet is powered by a set of slow and fast chargers that together have a peak load of 13 MW (megawatts). This is equivalent to the power used by a typical large factory. And they are thinking of expanding the fleet to 250 buses.

California utilities are finding that grid capacity is often adequate in the short term, but that upgrade needs likely will grow in the medium term.
Many other fleets also will need a lot of "juice." For example, a rough estimate of the power needed to serve a fleet of 200 delivery vans at an Amazon fulfillment center is about 4 MW. And for electric 18-wheelers, chargers may need up to 2 MW of power each; a recent proposal calls for charging stations every 100 miles along the U.S. West Coast’s I-5 corridor, highlighting concerns about EVs and the grid as each site targets a peak load of 23.5 MW.

Utilities need distribution planning
These examples show the need for more power at a given site than most utilities can provide without planning and investment. Meeting these needs often will require changes to primary and secondary power distribution systems (feeders that deliver power to distribution transformers and to end customers) and substation upgrades. For large loads, a new substation may be needed. A paper recently released by the California Electric Transportation Coalition estimates that for loads over 5 MW, distribution system and substation upgrades will be needed most of the time. According to the paper, typical utility costs are $1 million to $9 million for substation upgrades, $150,000 to $6 million for primary distribution upgrades, and $5,000 to $100,000 for secondary distribution upgrades. Similarly, Black and Veatch, in a paper on Electric Fleets, also provides some general guidance, shown in the table below, while recognizing that each site is unique.

California policy pushes utilities toward planning
In California, state agencies and a statewide effort called CALSTART have been funding demonstration projects and vehicle and charger purchases for several years to support grid stability as electrification ramps up. The California Air Resources Board voted in June to phase in zero-emission requirements for truck sales, mandating that, beginning in 2024, manufacturers must increase their zero-emission truck sales to 30-50 percent by 2030 and 40-75 percent by 2035. By 2035, more than 300,000 trucks will be zero-emission vehicles.

California utilities operate programs that work with fleet owners to install the necessary infrastructure for electric vehicle fleets. For example, Southern California Edison operates the Charge Ready Transport program for medium- and heavy-duty fleets. Normally, when customers request new or upgraded service from the utility, there are fees associated with the new upgrade. With Charge Ready, the utility generally pays these costs, and it will sometimes pay half the cost of chargers; the customer is responsible for the other half and for charger installation costs. Sites with at least two electric vehicles are eligible, but program managers report that at least five vehicles are often needed for the economics to make sense for the utility.

One way to do this is to develop and implement a phased plan, with some components sized for future planned growth and other components added as needed. Southern California Edison, for example, has 24 commitments so far, and has a five-year goal of 870 sites, with an average of 10 chargers per site. The utility notes that one charger usually can serve several vehicles and that cycling of charging, some storage, and other load management techniques through better grid coordination can reduce capacity needs (a nominal 10 MW load often can be reduced below 5 MW).

Through this program, utility representatives are regularly talking with fleet operators, and they can use these discussions to help identify needed upgrades to the utility grid. For example, California transit agencies are doing the planning to meet a California Air Resources Board mandate for 100 percent electric or fuel cell buses by 2040; utilities are talking with the agencies and their consultants as part of this process. California utilities are finding that grid capacity is often adequate in the short term, but that upgrade needs likely will grow in the medium term (seven to 10 years out). They can manage grid needs with good planning (school buses generally can be charged overnight and don’t need fast chargers), load management techniques and some energy storage to address peak needs.

Customer conversations drive planning elsewhere
We also spoke with a northeastern utility (wishing to be unnamed) that has been talking with customers about many issues, including fleets. It has used these discussions to identify a few areas where grid upgrades might be needed if fleets electrify. It is factoring these findings into a broader grid-planning effort underway that is driven by multiple needs, including fleets. Even within an integrated planning effort, this utility is struggling with the question of when to take action to prepare the electric system for fleet electrification: Should it act on state or federal policy? Should it act when the specific customer request is submitted, or is there something in between? Recognizing that any option has scheduling and cost allocation implications, it notes that there are no easy answers.

Many utilities need to start paying attention
As part of our research, we also talked with several other utilities and found that they have not yet looked at how fleets might relate to grid planning. However, several of these companies are developing plans to look into these issues in the next year. We also talked with a major truck manufacturer, also wishing to remain unnamed, that views grid limitations as a key obstacle to truck electrification. 

Based on these cases, it appears that fleet electrification can have a substantial impact on electric grids and that, while these impacts are small at present, they likely will grow over time. Fleet owners, electric utilities, and utility regulators need to start planning for these impacts now, so that grid improvements can be made steadily as electric fleets grow. Fleet and grid planning should happen in parallel, so that grid upgrades do not happen sooner or later than needed but are in place when needed, including the move toward a much bigger grid as EV adoption accelerates. These grid impacts can be managed and planned for, but the time to begin this planning is now.

U.S. Offshore Wind Power Strategy leverages UK offshore wind lessons, contract auctions, and supply chains to scale renewable energy, build wind farms, cut emissions, create jobs, and modernize the grid to meet 2030 climate goals.

Key Points

U.S. plan to scale offshore wind via UK-style contracts, turbines, and supply chains to meet 2030 clean energy goals

✅ Contract-for-difference price guarantees de-risk projects

✅ Scale turbines and ports to cut LCOE and boost capacity

✅ Build coastal grids, transmission, and workforce by 2030

As President Joe Biden’s administration puts its muscle behind wind power with plans to develop large-scale wind farms along the entire United States coastline, the administration can look at how the windiest nation in Europe is transforming its energy grid for an example of how to proceed.

In the search for renewable sources of energy, the United Kingdom has embraced wind power. In 2020, the country generated as much as 24 percent of its electricity from wind power across the grid — enough to supply 18.5 million homes, according to government statistics. 

With usually reliable winds, the U.K. currently has the highest number of offshore turbines installed in the world, with China at a close second.

Experts and industry leaders say it offers valuable lessons on creating a viable market for wind power at the ambitious scale the Biden administration hopes to meet in order to confront climate change and help transition the U.S. economy to renewable energy.

“The U.S. is going to benefit hugely from the early investment that European governments have put into offshore wind,” said Oliver Metcalfe, a wind power analyst at BloombergNEF in London, an independent research group.

Big American plans
On Oct. 13, the White House announced ambitious offshore wind plans to lease federal waters off of the East and West Coasts and Gulf of Mexico to develop commercial wind farms.

The move is part of Biden’s goal to have 30,000 megawatts of offshore wind power produced in the United States by 2030, with projects such as New York's record-setting approval highlighting the momentum. The White House says that would generate enough electricity to power more than 10 million homes and in the process create 77,000 jobs. 

But there is a chasm between where the U.S. is now and where it wants to be within the next decade when it comes to offshore wind power.

“We’re the first generation to understand the science and implications of climate change and we’re the last generation to be able to do something about it.”

The U.S. is not new to wind power; onshore wind in states such as Texas, Oklahoma and Iowa supplied 8.2 percent of the country’s total electricity generation in 2020, according to the U.S. Department of Energy. 

But despite its long coastlines, offshore wind has been a largely untapped resource in the U.S. With a population of about 332 million people, the U.S. currently has just two operational offshore wind farms — off Rhode Island and Virginia — with the capacity to produce 42 megawatts of electricity between them, far from the 1 gigawatt on-grid milestone many are watching. 

In contrast, the U.K., with a population of 67 million people, has 2,297 offshore wind turbines with the capacity to produce 10,415 megawatts of electricity.

Power station or a park?
Just outside of central Glasgow, the host city for the U.N. climate change conference known as COP26, the fruits of years of effort to move away from fossil fuels can be seen and heard

International financiers, including the World Bank are helping developing countries scale wind projects to meet climate goals.

Whitelee Windfarm, the U.K.’s largest onshore wind farm, spreads across 30 square miles on the Eaglesham Moor and includes more than 80 miles of trails for walking, cycling and horseback riding.

With its 539 megawatt capacity, it generates enough electricity for 350,000 homes — more than half the population of Glasgow. 

On a recent gusty fall day, Ian and Fiona Gardner, both 71, were walking their dogs among the wind farm’s 360-foot-tall turbines  

“This is a major contribution to Scotland, to become independent from oil by 2035,” Ian Gardner, an accountant, said. 

Thanks to the rapid technological advances in turbine technology, this wind farm that was completed in 2009, is now practically old school. The latest crop of onshore turbines typically generate double the current capacity of Whitelee’s turbines.

“It took us 20 years to build 2 gigawatts of power. And we’re going to double that in five  years,” said McQuade, an economist. “We can do that because machines are big, efficient, cheap and the supply chain is there.” 

The biggest operational offshore wind farm in the world right now, Hornsea Project One, is about 75 miles off England’s Yorkshire coast in the North Sea.

Owned and operated by Orsted, a former Danish oil and gas giant, in partnership with Global Infrastructure Partners, its 174 turbines have the capacity to generate 1.2 gigawatts — enough to power over 1 million homes and roughly equivalent to a nuclear power plant. 

Benj Sykes, Vice President of U.K. Offshore Wind at Orsted, called Hornsea One a “game changer” in a recent phone interview, citing it as an example of how the industry has scaled up its output to compete with traditional power plants.

But massive projects like Hornsea One took decades to get up and running, as well as government help. According to Malte Jansen, a research associate at the Centre of Environmental Policy at Imperial College London, the British government helped facilitate a “paradigm shift” in renewable energy in 2013.

The electricity market reform policy set up a framework to incentivize investment in offshore wind farms by creating an auction system that guarantees electricity prices to developers in 15-year contracts, alongside new contract awards that add 10 GW to the U.K. grid. 

This means there is no upside in terms of market price fluctuation, but there is no downside either. The policy essentially “de-risked the investment,” Jansen said.

The state contracts allowed the industry to innovate and learn how to develop even larger and more efficient turbines with blades that stretch as long as 267 feet, about three-quarters the size of a U.S. football field. 

While this approach helped companies and investors, it will also have an unintended beneficiary — the U.S., Metcalfe from BloombergNEF said. 

Developers are “taking the lessons they’ve learned building projects in Europe, the cost reductions that they’ve achieved building projects in Europe and are now bringing those to the U.S. market,” he said.
