Anyone who thinks rapid global decarbonization is out of reach should take a look at the floating wind turbine sector. Floating wind seemingly popped up out of nowhere in just the past couple of years, and it has already hooked up with the splashy new green hydrogen trend. Too bad those pesky cryptocurrency speculators are sucking up all the clean kilowatts, but that’s another new trend and a whole ‘nother can of worms.

Floating Wind & Green Hydrogen To The Rescue

For those of you new to the topic, putting a wind turbine on a platform that floats is a technologically difficult exercise, but the payoff is huge in terms of rapid decarbonization. Floating platforms can be tethered to the seabed in deeper waters and/or farther from shore, which takes advantage of prime wind speeds while minimizing opposition from coastal communities.

The green hydrogen angle comes in for squeezing the most available juice possible from wind turbines. Hydrogen is a zero emission fuel that can be combusted to run turbines, or deployed in a fuel cell to generate electricity. At the present time, though, almost all of the global hydrogen supply comes from natural gas. That’s going to change because low-cost renewable energy has upended the economics of hydrogen production, making it financially feasible to “split” hydrogen gas from water with an electrical current.

Since hydrogen acts as a transportable energy storage medium, water-splitting provides a way to salvage excess energy from wind turbines or solar panels. The case for wind turbines is especially strong because winds generally pick up at night, when electricity demand goes down.

Other sustainable hydrogen pathways include biogas, industrial waste gas, wastewater, and waste plastics, but water-splitting seems to be attracting the most attention these days.

Pie In The Sky? No, Wind Turbines That Float

Into this picture steps a venture called Cerulean Winds, which has come up with a financing formula for scaling the floating wind-plus-hydrogen connection to the national level.

The idea would have seemed far fetched just a few years ago, but both the floating wind industry and the green hydrogen industry are rapidly maturing.

“Cerulean utilises a tuned infrastructure project finance (IPF) construct with integrated delivery and finance that is proven for the offshore floating environment,” Cerulean explains. “At its core is the comprehensive understanding of risk for floating infrastructure and the most appropriate allocation of these risks across our partner and stakeholder ecosystem,” the company states.

Cerulean’s “Blueprint” model is aimed at cutting the timeline between applying for a license and producing clean kilowatts. According to the company, its Blueprint platform also provides for more flexibility than the conventional centralized power plant structure, which is a key point in the distributed energy landscape of today. Energy storage and cross-border trading are also in the mix.

Serial Oil & Gas Developers Turn To Green Hydrogen

The new Cerulean proposal is billed as the “UK’s largest offshore decarbonisation development.” At a cost of £10 billion, it would sport at least 200 wind turbines floating wind turbines with integrated green hydrogen systems, in two North Sea areas, West of Shetland and Central North Sea.

Before you get too excited, one leading aim of the project is to provide clean electricity to existing offshore facilities, namely, offshore oil and gas drilling sites. Cerulean projects that 3 gigawatts in hourly capacity will go to the oil and gas industry. Still, that leaves 1.5 gigawatts per hour in capacity for green hydrogen production systems to be located on shore.

If the offshore oil and gas angle sounds rather unappealing, it is. However, the reality is that switching millions of automobiles, buildings, and other systems over to clean power is a time consuming process. A movement is already afoot to replace diesel and gas generators on offshore drilling platforms with clean power. The Cerulean proposal is part of that trend, ramped up with the green hydrogen angle.

Cerulean has just submitted a seabed lease request to Marine Scotland, so if anything happens out there in the North Sea it could be a long way off. However, Cerulean has already set the contractor and financial wheels in motion, and in that regard the project does demonstrate that the oil and gas industry could pivot rapidly into low carbon mode, if it chose to do that.

“Cerulean Winds is led by serial entrepreneurs Dan Jackson and Mark Dixon, who have more than 25 years’ experience working together on large-scale offshore infrastructure developments in the oil and gas industry,” the company explains. “They believe the risk of not moving quickly on basin wide decarbonisation would wholly undermine the objectives set out in the recent North Sea Transition Deal.”

To sweeten the pot, Cerulean anticipates undercutting the cost of conventional gas turbine power for offshore platforms. According to the company, oil and gas operators would not incur any up-front costs from the switchover.

Floating Wind, Green Hydrogen, & Green Jobs, Jobs, Jobs

To make the case for speeding up the lease approval process, Jackson and Dixon are appealing to the potential for the wind-plus-hydrogen project to create thousands of new green jobs. Ideally the fossil energy jobs will phase out over time, but in the meanwhile Cerulean aims to show that the floating wind plus green hydrogen combo can maintain employment in the fossil sector while adding new green jobs to the economy, at scale. According to the company’s analysis, over the next five years the project will help preserve 160,000 oil and gas jobs while adding 200,000 new green jobs.

More Bad News For ExxonMobil

“The development of green hydrogen at scale and £1 billion hydrogen export potential” is another key pot-sweetener offered by Cerulean, and that should really give gas stakeholders the heebie-jeebies.

Looking at you, ExxonMobil. In terms of making global decarbonization happen, the company has lagged far behind Shell, BP, and other legacy fossil energy companies. Instead of pumping more money into proven clean tech fields like wind and solar, ExxonMobil banked on algae biofuel while doubling down on shale gas in recent years, apparently with the idea that it could continue making fossil energy relevant by comparing gas emissions to coal emissions.

The idea of natural gas as a “bridge fuel” has fallen flat for a number of reasons, including evidence that the recent spike in natural gas emissions may have offset any gains from pushing coal out of the power generation picture.

Now that hydrogen fuel cell demand is up, ExxonMobil and other natural gas stakeholders are been banking on increased demand for hydrogen to fuel the global economy’s thirst for natural gas. However, schemes like the Cerulean floating wind proposal are quickly shutting that window.

Gas stakeholders could try leaning on the exploding cryptocurrency market to pitch their wares. Speculative crypto mining is an energy intensive process that could help prop up both gas and coal producers for years to come.

To be clear, not all cryptocurrency is speculative. The firm Power Ledger, for example, is deploying a crypto-plus-blockchain model that helps electricity users share excess clean kilowatts.

It’s the speculative crypto market that has become a huge public relations problem for industries looking to decarbonize. Banking, real estate, auto sales and other high-dollar sectors have been getting cryptocurrency-curious, but energy consumption by crypto mining systems has become a public relations ball-and-chain.

As leading global corporations move into the supply chain phase of decarbonization, crypto miners are vulnerable. Switching to renewable energy is one solution, but in the context of the urgent need for climate action, any sector that adds to the global energy demand load will have to make the case that it is not simply playing carbon whack-a-mole with clean energy resources.

Survey Sunday: we asked how much home charging SHOULD cost, you answered

For the last few weeks, we’ve been running a sidebar survey about how much Electrek readers think it would cost to add EV charging systems to their homes. After receiving over twenty-four hundred responses, here’s what you told us.

In our previous survey, we asked readers why they chose to install solar panels at home. In the recap, many of our commenters mentioned having their systems systems pull double duty — charging home backup batteries and topping off their electric cars. That got us thinking: as more and more first-time EV owners look into the many benefits of home charging, how much do they expect to pay for home charging?

Based on over 2,400 responses, this is what you told us.

What do you expect to pay for home charging?


By the numbers; original content.

The most positive surprise was that more than a third of Electrek readers who responded to the poll already had 240V outlets in their garage, so they expected to pay effectively $0 – their homes are EV ready now!

Of the remaining 64%, 44% were fairly evenly split between a relatively straightforward ~$500-1,000 wiring job with a few wiring or panel upgrades while only about 18% expected to spend over $1,000 due to having an older home, a detached garage, or for some other (apparently pricey and/or inconvenient) reason.

Navigating the questions

Just like you would for home solar, we’d recommend getting a quote from several installers before making a decision. One of our trusted partners, Qmerit, offers a quote-sourcing service called PowerHouse. The service scans pricing from thousands of completed electrification installations across North America to provide the best quotes that take regional variability into account and work with homeowners to “bundle” chargers, installation, and even batteries.

America has arrived at an inflection point in which all of the technical, policy and financial elements are in place to support a societal shift toward whole-home electrification. Now what’s needed is a comprehensive way to assemble these complex elements into a simple, financeable, home-energy retrofit that makes it easier to implement.

QMERIT FOUNDER TRACY PRICE

Qmerit says its new bundling program can flag the potential for federal, state, and local utility incentives like the ones we’ve covered from Illinois utility ComEd and others that can reduce or even eliminate the upfront costs of home installations for many.

California hits back as CARB takes legal action against truck brands

California hits back as CARB takes legal action against truck brands

Following a lawsuit brought against the California Air Resources Board (CARB) by major heavy truck manufacturers over California’s emissions requirements, CARB has struck back with fresh lawsuit of its own alleging that the manufacturers violated the terms of the 2023 Clean Truck Partnership agreement to sell cleaner vehicles.

Daimler Truck North America, International Motors, Paccar and Volvo Group North America sued the California Air Resources Board in federal court this past August, seeking to invalidate the Clean Truck Partnership emissions reduction deal they signed with the state in 2023 to move away from traditional trucks and toward zero-emission vehicles (ZEVs). The main point of the lawsuit was that, because the incoming Trump Administration rolled back Environmental Protection Agency (EPA) policies that had previously given individual states the right to set their own environmental and emissions laws, the truck makers shouldn’t have to honor the deals signed with individual states.

“Plaintiffs are caught in the crossfire: California demands that OEMs follow preempted laws; the United States maintains such laws are illegal and orders OEMs to disregard them,” the lawsuit reads. “Accordingly, Plaintiff OEMs file this lawsuit to clarify their legal obligations under federal and state law and to enjoin California from enforcing standards preempted by federal law.”

After several weeks of waiting for a response, we finally have one: CARB is suing the OEMs right back, claiming that the initial suit proves the signing manufacturers, “(have) unambiguously stated that they do not intend to comply.”

In its lawsuit, CARB argues that monetary damages alone would not make the people of the State of California whole as far as damages are concerned, citing that the stated goal of the 2023 Clean Truck Partnership was, “to achieve emissions reductions that cannot be measured strictly in financial terms,” according to ACT-News.

The agency is asking the court to compel the truck companies to perform on their 2023 obligations or, failing that, to allow CARB to rescind the contract and recover its costs. A hearing on the truck makers’ request for a preliminary injunction was held Friday, with another court date set for November 21, when CARB will seek to dismiss the case brought forth by the truck brands. The outcome of these cases could shape how state and federal government agencies cooperation on emissions rules in the future.

New national law will turn large parking lots into solar power farms

New national law will turn large parking lots into solar power farms

Starting this month, parking lots in South Korea with more than 80 spaces will be required to install solar canopies and carports. But, unlike similar laws that have been proposed in the US, this new law doesn’t just apply to new construction – existing lots will have to comply as well!

South Korea’s Ministry of Trade, Industry and Energy announced in August that it has prepared an amendment to the Enforcement Decree of the Act on the Promotion of the Development, Use, and Diffusion of New and Renewable Energy to the effect that all publicly- and privately-owned parking lots in the Asian country with room for more than 80 vehicles will be compelled to add solar panels to their lots in a move designed to proactively expand renewable energy and create more solar and construction jobs.

In addition to creating jobs and working to stabilize the local grid with more renewable energy, the proposed solar canopies will offer a number of practical, day-to-day benefits for Korean drivers, as well.

The shaded structures will protect vehicles from heavy rain, snow, and the blistering summer sun — keeping interiors cooler, extending the life of plastics and upholstery, and even helping to preserve battery range in EVs and PHEVs by reducing their AC loads (and, of course, provide charging while the cars are parked).

To their credit, Ministry officials absolutely get it. “Through this mandatory installation,” one unnamed official told Asia Business Daily, “we expect to expand the distribution of eco-friendly renewable energy generation facilities while providing tangible benefits to the public. By utilizing idle land such as parking lots, we can maximize land use efficiency. In addition, installing canopy-type solar panels can provide shade underneath, offering noticeable comfort to people using parking lots during hot weather.”

The new rule was approved in late September, and is expected to go into effect later this month, with new installation projects set to begin immediately.

South Korea is proving that an idea like is practical. Here in the US, we’re proving that out, too – the Northwest Fire District in Arizona partnered with Standard Solar to build a conceptually similar, 657 kW solar carport system across 12 parking lots (shown, above) that delivers more than 1.23 million kWh of clean, emissions-free power annually and offsets the equivalent of 185,000 vehicles’ worth of harmful carbon emissions.

That’s just Arizona. In New York, a new initiative to help expand solar into parking lots has more than doubled commercially zoned land where EV charging stations can be sited, “freeing up” an additional 400 million square feet of space throughout the city. 

Sun-rich states like Texas, New Mexico, and Florida could also benefit, and even if we’re “just” adding fresh energy sources to municipal parking, dealer lots, and public schools, we could do a lot to reduce the cost of energy generation for the entire community. And, for what it’s worth, that seems to be right in line with the big reasons why people are choosing to add solar to their homes today.

What do you guys think – would something like this work in the US, or are we too far gone down the sophomoric, pseudo-libertarian rabbit hole to ever dig our way out? Let us know your take in the comments.
