This strategic misstep could lead to a loss of innovative capital and talent,
while competitors benefit from America's retreat from clean energy leadership.
Ultimately, this could reshape the global economic landscape, leaving the U.S. behind.
(01:44):
Kia has unveiled the PV5 WAV, a wheelchair-accessible electric vehicle
at the Future of the Car Summit in partnership with Motability Operations Lakelty.
This vehicle aims to enhance mobility for wheelchair users, their families and caregivers,
featuring a side entry system and third-row tip-up seat for convenience and safety.
(02:07):
The PV5 WAV will be produced at Kia's eco-friendly plant in Korea
and it highlights Kia's commitment to sustainable mobility.
The model includes innovations like a quick-use wheelchair ramp
and specialized fastening systems alongside software applications for users with disabilities.
Kia's collaboration with Motability, the UK's largest vehicle-leasing company
(02:32):
for persons with disabilities, underscores its dedication to accessibility.
The company plans to expand its accessible vehicle offerings to more regions,
aligning with its vision of becoming a leader in sustainable mobility solutions.
And now, pivot our discussion towards the main clean tech topic.
(02:59):
Alright everybody, welcome to another episode of Innovation Pulse,
where we break down the latest in clean tech and sustainable solutions.
I'm your host, Donna, and as always, I'm joined by the man who knows way too much
about renewable energy and is not afraid to show it, Yakov Lasker.
Thanks for that introduction, Donna. Always keeping me humble.
(03:21):
But yes, I've been diving into something fascinating that's happening
as we rapidly expand our wind energy infrastructure worldwide.
It's something that sounds almost like science fiction, but it's becoming a real concern.
Oh, I love a good renewable energy mystery. Lay it on me, Yakov.
Well, as countries race to meet their net zero targets, we're seeing massive expansion of offshore wind farms.
(03:46):
But here's the catch. We're discovering that in some conditions, wind farms can actually steel each other's wind.
Wait, what? How does a wind farm steel wind? That sounds like something from a cartoon.
It does sound strange, but it's a real phenomenon called the wake effect.
Basically, as wind turbines extract energy from the air, they slow down the wind behind them.
(04:10):
So if you have one wind farm and then build another one downwind from it,
that second farm gets less powerful wind and generates less electricity.
So it's like standing behind someone at a concert. They block your view, or in this case, your wind?
That's a pretty good analogy. The technical explanation is that spinning turbines create a wake as they extract energy from the wind.
(04:33):
This wake can stretch surprisingly far, more than 100 kilometers beyond very large offshore wind farms under certain weather conditions.
100 kilometers? That's like, what, 60 miles? That's way farther than I would have guessed.
Exactly, though researchers say it's more typically tens of kilometers.
(04:54):
But still, when you're planning offshore wind development, that's a significant distance to consider.
And studies suggest that if a wind farm is built upwind of another, it can reduce the downwind producer's energy output by as much as 10% or more.
That seems like a big deal for an industry where margins matter. Is this a new discovery?
(05:16):
The principle has been known for a while, but it's becoming more pressing for a few key reasons.
First, the sheer scale of offshore expansion happening right now. Second, modern wind farms are bigger and denser than ever before.
And third, countries are in a rush to meet climate targets, which means cramming more turbines into available ocean space.
(05:41):
I guess I never thought about the ocean getting crowded. But when you think about it, there are only so many prime spots for wind farms, right?
Right. Take the North Sea in Europe. It's seeing a massive wind boom, and simulations show that wake effects are likely to increase in the coming decades as more wind farms come online.
The denser and bigger the wind farm, the stronger the wake effect.
(06:04):
So do developers have a solution? I mean, can't they just space things out better?
That's part of the challenge. In the UK, they've launched a new research project this spring specifically to study this issue.
The project lead, Pablo Uro from the University of Manchester, points out that to achieve net zero, the UK needs to triple its offshore wind capacity in less than five years.
(06:28):
Triple in five years? That's ambitious.
Very. And Uro says this means deploying thousands more turbines, many of which will operate very close to existing ones.
So these wake effects are becoming more impactful. There are already disputes between UK offshore wind farm developers over potential wake impacts.
This reminds me of those old water rights disputes in the American West. You're stealing my water. Now it's, you're stealing my wind.
(06:56):
That's actually a common term for it, wind theft. Though as one Norwegian lawyer specializing in offshore wind, Iroq Finceros points out,
the term is a bit misleading because nobody actually owns the wind.
Fair point. So what makes understanding these wake effects so difficult?
Several things. Current guidelines on how much offshore wind farms should be spaced apart may not reflect how far these wakes actually reach.
(07:25):
Plus, turbines are getting much bigger. The latest models have blades spanning more than a hundred metres. That's the length of a football pitch.
One of these massive turbines can power around 18,000 to 20,000 average European households.
That's impressive. But I'm guessing bigger turbines might create bigger wake problems?
(07:48):
Exactly. A bigger rotor diameter may create a longer wake, though researchers say more study is needed on that specific aspect.
But the other complicating factor is that offshore wind farms are built in clusters.
When you have multiple farms, they all interact with each other in complex ways.
So it's not just farm A affecting farm B, but potentially farms C, D and E all in the mix too?
(08:13):
Precisely. Iroq says when you have six wind farms, understanding how they all interact becomes much more complex.
But that's exactly what we'll be facing as development continues.
Are there any international implications to this? I mean, wind doesn't respect national borders, right?
That's becoming a growing concern. Finzeros led a study looking at how a planned wind farm in Norway could negatively affect a downwind farm in Denmark.
(08:41):
He warns this could lead to legal and political conflicts between countries.
I hadn't even considered the cross-border aspect. I guess the North Sea touches multiple countries.
It does. And Iroq raises this point too. Currently the disputes in the UK are between UK wind farms,
but what happens when there's a dispute between a UK wind farm and a Dutch, Belgian or French one?
(09:05):
These kinds of international issues need to be anticipated.
From an economic standpoint, how big of a problem is this for developers?
It can be significant. Building offshore wind farms involves enormous costs, special vessels, complex installation procedures and more.
Developers need to project a certain energy output over 25 to 30 years to justify their investment.
(09:29):
Even a relatively small, unexpected reduction in energy output can make a project financially non-viable.
So losing 10% of your expected output because someone built a wind farm upwind of you could be the difference between profit and loss?
Absolutely. And this creates another risk Finzeros calls the race to the water phenomenon.
Countries rushing development to secure the best spots first, potentially ignoring other important aspects like marine environmental protection.
(09:59):
This all sounds like it could really slow down the transition to clean energy if not managed properly.
That's the concern. But Finzeros suggests there are solutions.
European countries could cooperate and consult with one another when planning wind farms and introduce clear regulations to manage wind as a shared resource.
(10:20):
Similar to how they handle other shared marine resources like cross-border oil deposits or fish stocks.
So treating wind like other natural resources that already have established international agreements?
Exactly. And he points out that these European countries generally have good political relations which helps.
Everyone shares the goal of decarbonizing energy sectors quickly, so fighting over wind isn't in anyone's interest.
(10:47):
And this isn't just a European issue, right?
Not at all. China is rapidly expanding its offshore wind farms and researchers there are also studying the growing impact of wake effects.
It's truly a global challenge as we shift to more renewable energy.
It's fascinating how each clean energy solution comes with its own unique challenges that we need to solve.
(11:10):
So what's the takeaway for our listeners?
I think it's that the transition to renewable energy isn't just about building more turbines.
It requires careful planning, international cooperation and new frameworks for managing shared resources like wind.
The good news is there's tremendous interest in solving these problems.
(11:31):
When Uro announced his research project in March, he was flooded with emails from interested parties.
That's encouraging. It sounds like the industry recognizes the issue and is working to address it.
Definitely. As Uro puts it, we need to understand this. We need to progress more on the modeling because we need this amount of offshore wind to get to net zero.
(11:54):
We have to deliver this.
Well, there you have it folks. The unexpected challenge of wind theft and the race to solve it.
Thanks for joining us for another episode of Innovation Pulse where we keep our finger on the beating heart of sustainability solutions.
Until next time, I'm Donna.
