Solar Is Now 33% Cheaper Than Gas Power in US, Guggenheim Says

O2 Tidal Turbine delivers tidal energy in Orkney, Scotland, supplying grid-connected renewable power via EMEC and enabling green hydrogen production, providing clean electricity with predictable generation from strong coastal currents.

Key Points

A 2 MW, grid-connected tidal device in Orkney that delivers clean power and enables EMEC green hydrogen production.

✅ 2 MW capacity; powers ~2,000 UK homes via EMEC grid

✅ Predictable renewable output from strong coastal currents

✅ Enables onshore electrolyzer to produce green hydrogen

“The world’s most powerful” tidal turbine has been hooked up to the onshore electricity grid in Orkney, a northerly archipelago in Scotland, and is ready to provide homes with clean, green electricity, even as a major UK offshore windfarm begins supplying power this week.

The tidal turbine, known as the O2, was developed by Scottish engineering firm Orbital Marine Power. On July 28, they announced O2 “commenced grid connected power generation” at the European Marine Energy Centre (EMEC) in Orkney, meaning it's all set up and providing energy to the local power grid, similar to another Scottish tidal project that recently powered nearly 4,000 homes.

The 74-meter-long (242-foot) turbine is said to be “the world’s most powerful” tidal turbine. It will lay in the waters off Orkney for the next 15 years with the capacity to meet the annual electricity demand of around 2,000 UK homes. The 2MW turbine is also set to power the EMEC’s land-based electrolyzer that will generate green hydrogen (hydrogen made without fossil fuels) that can also be used as a clean energy source, in a UK energy system that recently set a wind generation record for output.

“Our vision is that this project is the trigger to the harnessing of tidal stream resources around the world and, alongside investment in UK offshore wind, to play a role in tackling climate change whilst creating a new, low-carbon industrial sector,” Orbital CEO, Andrew Scott, said in a press release.

Tidal energy is harnessed by converting energy from the natural rise and fall of ocean tides and currents. The O2 turbine consists of two submerged blades with a 20-meter (65-foot) diameter attached to a turbine that will move with the shifting currents of Orkney’s coast to generate electricity. Electricity is then transferred from the turbine along the seabed via cables towards the local onshore electricity network, a setup also being used by a Nova Scotia tidal project to supply the grid today.

This method of harnessing energy is not just desirable because it doesn't release carbon emissions, but it’s more predictable than other renewable energy sources, such as solar or Scotland's wind farms that can be influenced by weather conditions. Tidal energy production is still in its infancy and there are relatively few large-scale tidal power plants in the world, but many argue that some parts of the world could potentially draw huge benefits from this innovative form of hydropower, especially coastal regions with strong currents such as the northern stretches of the UK and the Bay of Fundy in Atlantic Canada.

The largest tidal power operation in the world is the Sihwa Lake project on the west coast of South Korea, which harnesses enough power to support the domestic needs of a city with a population of 500,000 people. However, once fully operational, the MeyGen tidal power project in northern Scotland hopes to snatch its title.

Hydrogen vs Battery-Electric Vehicles compare FCEV and BEV tech for range, charging and refueling, zero-emissions, infrastructure in Canada, highlighting urban commuting, heavy-duty use, fast 5-minute fills, 30-minute fast charging, and renewable hydrogen from surplus wind.

Key Points

Hydrogen FCEVs suit long range and heavy-duty use; BEVs excel in urban commutes with overnight charging.

✅ FCEVs refuel in about 5 minutes; ideal for long range and heavy duty.

✅ BEVs fit urban commuting with home or night charging; fewer stops.

✅ Hydrogen enables energy storage from surplus wind and hydro power.

We’re constantly hearing that battery-electric cars are the future, as automakers pursue Canada-U.S. collaboration on EVs across the industry, so I was surprised to see that companies like Toyota, Honda and Hyundai are making hydrogen fuel-cell cars. Which technology is better? Could hydrogen still win? – Pete, Kingston

They’re both in their electric youth, relatively speaking, but the ultimate winner in the race between hydrogen and battery electric will likely be both.

“It’s not really a competition – they’ll both co-exist and there will also be plug-in hydrogen hybrids,” said Walter Merida, director of the Clean Energy Research Centre at the University of British Columbia. “Battery-electric vehicles [BEVs] are better for an urban environment where you have time to recharge and fuel-cell electric vehicles [FCEVs] are better-suited for long range and heavy duty.”

Last year, there were 9,840 BEVs sold in Canada, up from 5,130 the year before. If you include plug-in hybrids, the number sold in 2017 grows to 18,560, though many buyers now face EV shortages and wait times amid high gasoline prices.

And how many hydrogen vehicles were sold in Canada last year?

#google#

None – although Hyundai leased out about a half-dozen hydrogen Tucsons in British Columbia for $599 a month, which included fuel from Powertech labs in Surrey.

In January, Toyota announced it will be selling the Mirai in Quebec later this year. And Hyundai said it will offer about 25 Nexos for sale.

“It’s chicken or egg,” said Michael Fowler, a professor of chemical engineering at the University of Waterloo. “Car manufacturers won’t release cars into the market unless there’s a refuelling station and companies won’t build a refuelling station unless there are cars to fuel.”

Right now, there are no retail hydrogen refuelling stations in Canada. While there are plans under way to add stations in B.C., Ontario and Quebec, we’re still behind Japan, Europe and California, though experts outline how Canada can capitalize on the U.S. EV pivot to accelerate progress.

“In 2007, Ontario had a hydrogen strategy and they were starting to develop hydrogen vehicles and they dropped that in favour of the Green Energy Act and it was a complete disaster,” Fowler said. “The reality is the government of the day listened to the wrong people.”

It’s tough to pinpoint a single reason why governments focused on building charging stations instead of hydrogen stations, Merida said.

“It’s ironic, you know – the fuel cell was invented in Vancouver. Geoffrey Ballard was one of the pioneers of this technology,” Merida said. “And for a while, Canada was a global leader, but eventually government programs were discontinued and that was very disruptive to the sector.”

HYDROGEN FOR THE MASSES?

While we tend to think of BEVs when we think of electric cars, fuel-cell vehicles are electric, too; the hydrogen passes through a fuel cell stack, where it mixes with oxygen from the atmosphere to produce an electric current.

That current powers electric motors to drive the wheels and extra energy goes to a battery pack that’s used to boost acceleration (it’s also charged by regenerative braking).

Except for water that drips out of the hydrogen car, they’re both zero-emission on the road.

But a big advantage for hydrogen is that, if you can find a station, you can pull up to a pump and fill up in five minutes or less – the same way we do now at nearly 12,000 gas stations.

Compare that with fast-charging stations that can charge a battery to 80 per cent in 30 minutes – each station only handles one car at a time. What if you get there and it’s busy – or broken? And right now, there are only 139 of them in Canada.

And at slower, Level 2 stations, cars have to be plugged in for hours to recharge.

In a 2018 KPMG survey of auto executives, 55 per cent said that moves to switch entirely to pure battery-electric vehicles will fail because there won’t be enough charging stations, and some critics argue the 2035 EV mandate is delusional given infrastructure constraints.

“Ontario just invested $20-million in public charging stations and that’s going to service 100 or 200 cars a day,” Fowler said. “If you were to invest that in hydrogen stations, you’d be able to service thousands of cars a day.”

And when you do charge at a station, you might not be using clean power, as 18% of Canada’s 2019 electricity came from fossil fuels according to national data, Fowler said.

“At least in Ontario, in order to charge at a public station during the day, you have to rev up a natural-gas plant somewhere,” Fowler said. “So the only way you’re getting zero emissions is when you can charge at night using excess nuclear, hydro or wind that’s not being used.”

But hydrogen can be made when surplus green energy is stored, Fowler said.

“In Ontario, we have lots of wind in the spring and the fall, when we don’t need the electricity,” he said.

And eventually, you’ll be able to connect your fuel-cell vehicle to the grid and sell the power it produces, Merida said.

“The amount of power generation you have in these moving platforms is quite significant,” Merida said.

There are other strikes against battery-electric, including reduced range by 30 per cent or more in the winter and the need to upgrade infrastructure such as electrical transformers so they can handle more than just a handful of cars on each street charging at night, Fowler said.

In that KPMG survey, executives predicted a nearly equal split between BEVs, FCEVs, hybrids and gasoline engines by 2040.

“Battery-electric vehicles will serve a certain niche – they’ll be small commuter vehicles in certain cities,” Fowler said. “But for the way we use cars today – the family car, the suburban car, buses and probably trucks – it will be the fuel cell.”

IEA Grid Expansion Warning highlights stalled investment in power lines and transmission infrastructure, risking renewable energy rollout for solar, wind, EVs, and heat pumps, and jeopardizing climate targets under the Paris Agreement amid connection bottlenecks.

Key Points

IEA alert urging grid investment to expand transmission, connect renewables, and keep 1.5 C climate goals on track.

✅ 80 million km of lines needed by 2040, per IEA

✅ Investment must double to $600B annually by 2030

✅ Permitting delays stall major cross-border projects

Stalled spending on electrical grids worldwide is slowing the rollout of renewable energy and could put efforts to limit climate change at risk if millions of miles of power lines are not added or refurbished in the next few years, the International Energy Agency said.

The Paris-based organization said in the report Tuesday that the capacity to connect to and transmit electricity is not keeping pace with the rapid growth of clean energy technologies such as solar and wind power, electric cars and heat pumps being deployed to move away from fossil fuels, a gap reflected in why the U.S. grid isn't 100% renewable today.

IEA Executive Director Fatih Birol told The Associated Press in an interview that there is a long line of renewable projects waiting for the green light to connect to the grid, including UK renewable backlog worth billions. The stalled projects could generate 1,500 gigawatts of power, or five times the amount of solar and wind capacity that was added worldwide last year, he said.

“It’s like you are manufacturing a very efficient, very speedy, very handsome car — but you forget to build the roads for it,” Birol said.

If spending on grids stayed at current levels, the chance of holding the global increase in average temperature to 1.5 degrees Celsius above pre-industrial levels — the goal set by the 2015 Paris climate accords — “is going to be diminished substantially,” he said.

The IEA assessment of electricity grids around the globe found that achieving the climate goals set by the world’s governments would require adding or refurbishing 80 million kilometers (50 million miles) of power lines by 2040 — an amount equal to the existing global grid in less than two decades.

Annual investment has been stagnant but needs to double to more than $600 billion a year by 2030, the agency said, with U.S. grid overhaul efforts aiming to accelerate upgrades.

It’s not uncommon for a single high-voltage overhead power line to take five to 13 years to get approved through bureaucracy in advanced economies, while lead times are significantly shorter in China and India, according to the IEA, though a new federal rule seeks to boost transmission planning.

The report cited the South Link transmission project to carry wind power from northern to southern Germany. First planned in 2014, it was delayed after political opposition to an overhead line meant it was buried instead, while more pylons in Scotland are being urged to keep the lights on, industry says. Completion is expected in 2028 instead of 2022.

Other important projects that have been held up: the 400-kilometer (250-mile) Bay of Biscay connector between Spain and France, now expected for 2028 instead of 2025, and the SunZia high-voltage line to bring wind power from New Mexico to Arizona and California, while Pacific Northwest goals are hindered by grid limits. Construction started only last month after years of delays.

On the East Coast, the Avangrid line to bring hydropower from Canada to New England was interrupted in 2021 following a referendum in Maine, as New England's solar growth is also creating tension over who pays for grid upgrades. A court overturned the statewide vote rejecting the project in April.

Green Hydrogen for Steelmaking enables decarbonization in Germany by powering electrolyzers with wind turbines at Salzgitter. Partners Vestas, Avacon, and Linde support renewable hydrogen for iron ore reduction, cutting CO2 in heavy industry.

Key Points

Hydrogen from renewable-powered electrolysis replacing coal in iron ore reduction, cutting CO2 emissions from steelmaking

✅ 30 MW Vestas wind farm powers 2x1.25 MW electrolyzers.

✅ Salzgitter, Avacon, Linde link sectors to replace fossil fuels.

✅ Targets CO2 cuts in iron ore reduction and steel smelting.

A major green hydrogen facility in Germany has started operations, with those behind the project hoping it will help to decarbonize the energy-intensive steel industry in the years ahead. 

The "WindH2" project involves German steel giant Salzgitter, E.ON subsidiary Avacon and Linde, a firm specializing in engineering and industrial gases, and aligns with calls for hydrogen-ready power plants in Germany today.

Hydrogen can be produced in a number of ways. One method includes using electrolysis, with an electric current splitting water into oxygen and hydrogen, and advances in PEM hydrogen technology continue to improve efficiency worldwide.

If the electricity used in the process comes from a renewable source such as wind or solar, as underscored by recent German renewables gains, then it's termed "green" or "renewable" hydrogen.

The development in Germany is centered around seven new wind turbines operated by Avacon and two 1.25 megawatt (MW) electrolyzer units installed by Salzgitter Flachstahl, which is part of the wider Salzgitter Group. The facilities were presented to the public this week. 

The turbines, from Vestas, have a hub height of 169 meters and a combined capacity of 30 MW. All are located on premises of the Salzgitter Group, with three situated on the site of a steel mill in the city of Salzgitter, Lower Saxony, northwest Germany, where grid expansion woes can affect project timelines.

The hydrogen produced using renewables will be utilized in processes connected to the smelting of iron ore. Total costs for the project come to roughly 50 million euros (around $59.67 million), with the building of the electrolyzers subsidized by state-owned KfW, while a national net-zero roadmap could reduce electricity costs over time.

"Green gases have the wherewithal to become 'staple foodstuff' for the transition to alternative energies and make a considerable contribution to decarbonizing industry, mobility and heat," E.ON's CEO, Johannes Teyssen, said in a statement issued Thursday.

"The jointly realized project symbolizes a milestone on the path to virtually CO2 free production and demonstrates that fossil fuels can be replaced by intelligent cross-sector linking," he added.

According to the International Energy Agency, the iron and steel sector is responsible for 2.6 gigatonnes of direct carbon dioxide emissions each year, a figure that, in 2019, was greater than the direct emissions from sectors such as cement and chemicals. 

It adds that the steel sector is "the largest industrial consumer of coal, which provides around 75% of its energy demand."

The project in Germany is not unique in focusing on the role green hydrogen could play in steel manufacturing.

Across Europe, projects are also exploring natural gas pipe storage to balance intermittent renewables and enable sector coupling.

H2 Green Steel, a Swedish firm backed by investors including Spotify founder Daniel Ek, plans to build a steel production facility in the north of the country that will be powered by what it describes as "the world's largest green hydrogen plant."

In an announcement last month the company said steel production would start in 2024 and be based in Sweden's Norrbotten region.

Other energy-intensive industries are also looking into the potential of green hydrogen, and examples such as Schott's green power shift show parallel decarbonization. A subsidiary of multinational building materials firm HeidelbergCement has, for example, worked with researchers from Swansea University to install and operate a green hydrogen demonstration unit at a site in the U.K.

Ukraine Wind Energy Resilience shields the grid with wind power along the Black Sea, dispersing turbines to withstand missile attacks, accelerate clean energy transition, aid EU integration, and strengthen energy security and rapid recovery.

Key Points

A strategy in Ukraine using wind farms to harden the grid, ensure clean power, and speed recovery from missile strikes.

✅ Distributed turbines reduce single-point-of-failure risk

✅ Faster repair of substations and lines than power plants

✅ Supports EU-aligned clean energy and grid security goals

The giants catch the wind with their huge arms, helping to keep the lights on in Ukraine — newly built windmills, on plains along the Black Sea.

In 15 months of war, Russia has launched countless missiles and exploding drones at power plants, hydroelectric dams and substations, trying to black out as much of Ukraine as it can, as often as it can, even amid talk of limiting attacks on energy sites that has surfaced, in its campaign to pound the country into submission.

The new Tyligulska wind farm stands only a few dozen miles from Russian artillery, but Ukrainians say it has a crucial advantage over most of the country’s grid, helping stabilize the system even as electricity exports have occasionally resumed under fire.

A single, well-placed missile can damage a power plant severely enough to take it out of action, but Ukrainian officials say that doing the same to a set of windmills — each one tens of meters apart from any other — would require dozens of missiles. A wind farm can be temporarily disabled by striking a transformer substation or transmission lines, but these are much easier to repair than power plants.

“It is our response to Russians,” said Maksym Timchenko, CEO of DTEK Group, the company that built the turbines in the southern Mykolaiv region — the first phase of what is planned as Eastern Europe’s largest wind farm. “It is the most profitable and, as we know now, most secure form of energy.”

Ukraine has had laws in place since 2014 to promote a transition to renewable energy, both to lower dependence on Russian energy imports, with periods when electricity exports resumed to neighbors, and because it was profitable. But that transition still has a long way to go, and the war makes its prospects, like everything else about Ukraine’s future, murky.

In 2020, 12% of Ukraine’s electricity came from renewable sources — barely half the percentage for the European Union. Plans for the Tyligulska project call for 85 turbines producing up to 500 megawatts of electricity. That’s enough for 500,000 apartments — an impressive output for a wind farm, but less than 1% of the country’s prewar generating capacity.

After the Kremlin began its full-scale invasion of Ukraine in February 2022, the need for new power sources became acute, prompting deliveries such as a mobile gas turbine power plant to bolster capacity. Russia has bombarded Ukraine’s power plants and cut off delivery of the natural gas that fueled some of them.

Russian occupation forces have seized a large part of the country’s power supply, and Russia has built power lines to reactivate the Zaporizhzhia plant in occupied territory, ensuring that its output does not reach territory still held by Ukraine. They hold the single largest generator, the 5,700-megawatt Zaporizhzhia Nuclear Power Plant, which has been damaged repeatedly in fighting and has stopped transmitting energy to the grid, with UN inspectors warning of mines at the site during recent visits. They also control 90% of Ukraine’s renewable energy plants, which are concentrated in the southeast.

The postwar recovery plans Ukraine has presented to supporters including the European Union, which it hopes to join, feature a major new commitment to clean energy, even as a controversial proposal on Ukraine’s nuclear plants continues to stir debate.

California EV Sales 2023 show rising BEV market share, strong Tesla Model Y and Model 3 demand, hybrid growth, and ICE decline, per CNCDA Q3 data, underscoring California auto trends and ZEV policy momentum.

Key Points

BEVs hit 21.5% YTD in 2023 (22.3% in Q3); 35.4% with hybrids, as ICE share fell and Tesla led the California market.

✅ BEVs 21.5% YTD; 22.3% in Q3 per CNCDA data

✅ Tesla Model Y, Model 3 dominate; 62.9% BEV share

✅ ICE share down to 64.6%; hybrids lift to 35.4% YTD

The California New Car Dealers Association (CNCDA) reported on November 1, 2023, that sales of battery electric cars accounted for 21.5% of new car sales in the Golden State during the first 9 months of the year and 22.3% in the third quarter. At the end of Q3 in 2022, sales of electric cars stood at 16.4%. In 2021, that number was 9.1%. So, despite all the weeping and wailing and gnashing of teeth lately about green new car wreck warnings in some coverage, the news is pretty good, at least in California.

When hybrid and hydrogen fuel cell vehicles are included in the calculations, the figure jumps up 35.4% for all vehicles sold year to date in California. Not surprisingly this means EVs still trail gas cars in the state, with the CNCDA reporting ICE market share (including gasoline and diesel vehicles) was 64.6% so far this year, down from 71.6% in 2022 and 88.4% in 2018.

California is known as the vanguard for automotive trends in the country, with shifts in preferences and government policy eventually spreading to the rest of the country. While the state’s share of electric cars exceeds one fifth of all vehicles sold year to date, the figure for the US as a whole stands at 7.4%, with EV sales momentum into 2024 continuing nationwide. California has banned the sale of gas-powered vehicles starting in 2035, and its push toward electrification will require a much bigger grid to support charging, although the steady increase in the sale of electric cars suggests that ban may never need to be implemented as people embrace the EV revolution.

Not surprisingly, when digging deeper into the sales data, the Tesla Model Y and Model 3 dominate sales in the state’s electric car market this year, at 103,398 and 66,698 respectively. Tesla’s overall market share of battery electric car sales is at 62.9%. In fact, the Tesla Model Y is the top selling vehicle overall in California, followed by the Model 3, the Toyota RAV4 (40,622), and the Toyota Camry (39,293).

While that is good news for Tesla, its overall market share has slipped from 71.8% year to date last year at this time. Competing models from brands like Chevrolet, BMW, Mercedes, Hyundai, Volkswagen, and Kia have been slowly eating into Tesla’s market share. Overall, in California, Toyota is the sales king with 15% of sales, even as the state leads in EV charging deployment statewide, followed by Tesla at 13.5%. In the second quarter, Tesla narrowly edged out Toyota for top sales in the state before sales swung back in Toyota’s favor in the third quarter.

That being said, Tesla’s sales in the state climbed by 38.5% year to date, while Toyota’s actually shrank by 0.7%. Time will tell if Tesla’s popularity with the state’s car buyers improves and it can overtake Toyota for the 2023 crown, even as U.S. EV market share dipped in early 2024, or if other EV makers can offer better products at better prices and lure California customers who want to purchase electric cars away from the Tesla brand. Certainly, no company can expect to have two thirds of the market to itself forever.
