S… Speaker 5 (5_3_Windship Technology _ The Future of Shipping)

The most likely answer to the question, how will we power ships in our green future,

0:05

S… Speaker 5 (5_3_Windship Technology _ The Future of Shipping)

will be a mix of alternative fuels and power sources.

0:08

S… Speaker 5 (5_3_Windship Technology _ The Future of Shipping)

And if a company in the south of England have anything to do with it,

0:11

S… Speaker 5 (5_3_Windship Technology _ The Future of Shipping)

that will include an energy source older than shipping itself, wind.

0:22

S… Speaker 2 (5_3_Windship Technology _ The Future of Shipping)

It's a big day for the Windship Technologies team

0:25

S… Speaker 2 (5_3_Windship Technology _ The Future of Shipping)

at the University of Southampton's R.J. Mitchell Wind Tunnel.

0:29

S… Speaker 2 (5_3_Windship Technology _ The Future of Shipping)

For a century now, this tunnel has been used for testing racing cars,

0:33

S… Speaker 2 (5_3_Windship Technology _ The Future of Shipping)

marine vessels and military aircraft.

0:36

S… Speaker 2 (5_3_Windship Technology _ The Future of Shipping)

But today, this small, self-funded team is making fine aerodynamic adjustments

0:41

S… Speaker 2 (5_3_Windship Technology _ The Future of Shipping)

to a technology that they believe could soon be on the front line in the war against climate change.

0:47

S… Speaker 3 (5_3_Windship Technology _ The Future of Shipping)

Well, today what we're trying to do is improve the efficiency of the wing

0:50

S… Speaker 3 (5_3_Windship Technology _ The Future of Shipping)

and basically produce more thrust, more driving force for the ship.

0:55

S… Speaker 7 (5_3_Windship Technology _ The Future of Shipping)

Let's go for it. Good for a 20.

0:57

S… Speaker 7 (5_3_Windship Technology _ The Future of Shipping)

Let's go 20 minutes per second, please.

1:01

S… Speaker 2 (5_3_Windship Technology _ The Future of Shipping)

Today, a 120th scale model of the Windship System's wings

1:05

S… Speaker 2 (5_3_Windship Technology _ The Future of Shipping)

is being put through its paces.

1:08

S… Speaker 2 (5_3_Windship Technology _ The Future of Shipping)

Painstaking testing like this, along with computational fluid dynamic modelling,

1:13

S… Speaker 2 (5_3_Windship Technology _ The Future of Shipping)

have given the team confidence that this is a zero-carbon propulsion system

1:17

S… Speaker 2 (5_3_Windship Technology _ The Future of Shipping)

for some of the ocean's largest and thirstiest vessels

1:21

S… Speaker 2 (5_3_Windship Technology _ The Future of Shipping)

in an increasingly regulated environment.

1:25

S… Speaker 2 (5_3_Windship Technology _ The Future of Shipping)

Observing the tests on the scale model wings with an independent eye

1:29

S… Speaker 2 (5_3_Windship Technology _ The Future of Shipping)

is Emeritus Professor of Ship Dynamics, Philip Wilson.

1:33

S… Speaker 4 (5_3_Windship Technology _ The Future of Shipping)

They are exactly the same as an aeroplane.

1:35

S… Speaker 4 (5_3_Windship Technology _ The Future of Shipping)

Instead of that way, they're that way.

1:37

S… Speaker 2 (5_3_Windship Technology _ The Future of Shipping)

So they don't need the massive surface area of sails, traditional sails?

1:41

S… Speaker 4 (5_3_Windship Technology _ The Future of Shipping)

They're different technology.

1:43

S… Speaker 2 (5_3_Windship Technology _ The Future of Shipping)

And that's an important point.

1:44

S… Speaker 2 (5_3_Windship Technology _ The Future of Shipping)

This is a very different technology to using conventional sails.

1:48

S… Speaker 2 (5_3_Windship Technology _ The Future of Shipping)

In spite of the name, the Windship Propulsion System only begins with aerodynamics.

1:55

S… Speaker 2 (5_3_Windship Technology _ The Future of Shipping)

The innovative drive train system also uses an electric generator

1:59

S… Speaker 2 (5_3_Windship Technology _ The Future of Shipping)

that kicks in when needed.

2:02

S… Speaker 2 (5_3_Windship Technology _ The Future of Shipping)

The exhaust gases from the generator are cleaned in a carbonator,

2:05

S… Speaker 2 (5_3_Windship Technology _ The Future of Shipping)

and the heat from this reaction and the natural temperature of the exhaust gas

2:10

S… Speaker 2 (5_3_Windship Technology _ The Future of Shipping)

is used to power a steam turbine,

2:12

S… Speaker 2 (5_3_Windship Technology _ The Future of Shipping)

which in turn generates more electrical energy.

2:15

S… Speaker 2 (5_3_Windship Technology _ The Future of Shipping)

All this energy is fed into the electric motor,

2:19

S… Speaker 2 (5_3_Windship Technology _ The Future of Shipping)

driving the propeller in harmony with the thrust from the rigs.

2:23

S… Speaker 2 (5_3_Windship Technology _ The Future of Shipping)

And all that is emitted from the exhaust is clean, white vapour.

2:28

S… Speaker 3 (5_3_Windship Technology _ The Future of Shipping)

With our carbon capture system and heat recovery,

2:31

S… Speaker 3 (5_3_Windship Technology _ The Future of Shipping)

we actually achieve true zero.

2:34

S… Speaker 3 (5_3_Windship Technology _ The Future of Shipping)

So basically no CO2, no NOx, no SOX and no black soot, basically.

2:39

S… Speaker 3 (5_3_Windship Technology _ The Future of Shipping)

So the exhaust fumes that are coming out of the back of the vessel

2:42

S… Speaker 3 (5_3_Windship Technology _ The Future of Shipping)

are actually breathable.

2:44

S… Speaker 1 (5_3_Windship Technology _ The Future of Shipping)

It's a wind-driven technology,

2:47

S… Speaker 1 (5_3_Windship Technology _ The Future of Shipping)

so huge amounts, obviously free and emission-free from the rigs,

2:50

S… Speaker 1 (5_3_Windship Technology _ The Future of Shipping)

coupled with the electric drive system

2:53

S… Speaker 1 (5_3_Windship Technology _ The Future of Shipping)

and carbon capture for the small amount of fossil fuels that we do use.

2:58

S… Speaker 1 (5_3_Windship Technology _ The Future of Shipping)

So truly not net zero, not planting trees,

3:01

S… Speaker 1 (5_3_Windship Technology _ The Future of Shipping)

but really zero technology.

3:03

S… Speaker 2 (5_3_Windship Technology _ The Future of Shipping)

Today, end plates have been added to the wings,

3:05

S… Speaker 2 (5_3_Windship Technology _ The Future of Shipping)

an adjustment that is expected to deliver additional zero-carbon thrust.

3:10

S… Speaker 2 (5_3_Windship Technology _ The Future of Shipping)

With Southampton University post-graduate students assisting,

3:16

S… Speaker 2 (5_3_Windship Technology _ The Future of Shipping)

smoke and ultraviolet light highlights the fluid dynamics that create a powerful side force.

3:22

S… Speaker 2 (5_3_Windship Technology _ The Future of Shipping)

And in the control room, the results, as expected, are impressive.

3:27

S… Speaker 4 (5_3_Windship Technology _ The Future of Shipping)

The tests today were really good.

3:30

S… Speaker 4 (5_3_Windship Technology _ The Future of Shipping)

Windship technology did some tests about a year ago,

3:32

S… Speaker 4 (5_3_Windship Technology _ The Future of Shipping)

and at that point they didn't put end plates on these sails.

3:36

S… Speaker 4 (5_3_Windship Technology _ The Future of Shipping)

And so this time round they looked at the effects of the end plates.

3:39

S… Speaker 4 (5_3_Windship Technology _ The Future of Shipping)

That's really encouraging, actually more than encouraging, 20% more side force.

3:44

S… Speaker 2 (5_3_Windship Technology _ The Future of Shipping)

That side force should convert into 12- to 13-knot top speeds for any future windship-powered vessels.

3:52

S… Speaker 1 (5_3_Windship Technology _ The Future of Shipping)

Where we're targeting bulkers and tankers are burning sort of 25 tonnes of fuel a day,

3:57

S… Speaker 1 (5_3_Windship Technology _ The Future of Shipping)

and that's emitting close to 100 tonnes of CO2 a day.

4:01

S… Speaker 6 (5_3_Windship Technology _ The Future of Shipping)

That's each ship?

4:02

S… Speaker 1 (5_3_Windship Technology _ The Future of Shipping)

That's each ship.

4:03

S… Speaker 1 (5_3_Windship Technology _ The Future of Shipping)

With our technology, on trans-oceanic routes, we need wind routes.

4:08

S… Speaker 1 (5_3_Windship Technology _ The Future of Shipping)

We are down at 7 to 8 tonnes, and the fuel we use is therefore emission-free.

4:14

S… Speaker 1 (5_3_Windship Technology _ The Future of Shipping)

So just on a straight economics, we've cut two-thirds of the fuel bill.

4:18

S… Speaker 2 (5_3_Windship Technology _ The Future of Shipping)

And those projected savings come without loss of cargo capacity.

4:23

S… Speaker 2 (5_3_Windship Technology _ The Future of Shipping)

There's also enough space to sail under some of the world's major bridges into port.

4:28

S… Speaker 2 (5_3_Windship Technology _ The Future of Shipping)

The vertical wings drop down to 12 metres, lower than the clearance of many conventional ships.

4:35

S… Speaker 2 (5_3_Windship Technology _ The Future of Shipping)

Could you apply any of this technology to an existing fleet?

4:39

S… Speaker 1 (5_3_Windship Technology _ The Future of Shipping)

Rigs are fully retrofittable.

4:41

S… Speaker 1 (5_3_Windship Technology _ The Future of Shipping)

You don't get the same savings that you can with the full drivetrain system,

4:44

S… Speaker 1 (5_3_Windship Technology _ The Future of Shipping)

but we can still get 30% to 40% savings.

4:47

S… Speaker 1 (5_3_Windship Technology _ The Future of Shipping)

So the first step is to get rigs on your ship.

4:51

S… Speaker 1 (5_3_Windship Technology _ The Future of Shipping)

Retrofitting a drivetrain is a little harder,

4:53

S… Speaker 1 (5_3_Windship Technology _ The Future of Shipping)

so we're probably looking at new-build type for that.

4:56

S… Speaker 2 (5_3_Windship Technology _ The Future of Shipping)

Wind tunnel results and extensive computer modelling

4:58

S… Speaker 2 (5_3_Windship Technology _ The Future of Shipping)

both indicate that ships that might one day use this innovative technology

5:03

S… Speaker 2 (5_3_Windship Technology _ The Future of Shipping)

will be cheaper to run than conventional tonnage.

5:06

S… Speaker 2 (5_3_Windship Technology _ The Future of Shipping)

It's potentially a compelling proposition.

5:09

S… Speaker 1 (5_3_Windship Technology _ The Future of Shipping)

The worldwide IMO-type legislation will help encourage our shipping community,

5:14

S… Speaker 1 (5_3_Windship Technology _ The Future of Shipping)

which is relatively conservative, as a lot of big areas are,

5:18

S… Speaker 1 (5_3_Windship Technology _ The Future of Shipping)

to move in the right direction.

5:19

S… Speaker 2 (5_3_Windship Technology _ The Future of Shipping)

So what began as the simple sketches of a former ocean racer

5:23

S… Speaker 2 (5_3_Windship Technology _ The Future of Shipping)

and a blend of innovative engineering know-how

5:26

S… Speaker 2 (5_3_Windship Technology _ The Future of Shipping)

has undergone rigorous refinement and scientific testing

5:29

S… Speaker 2 (5_3_Windship Technology _ The Future of Shipping)

to become a cost-reducing, zero-carbon proposition,

5:34

S… Speaker 2 (5_3_Windship Technology _ The Future of Shipping)

looking to take its place on our oceans

5:36

S… Speaker 2 (5_3_Windship Technology _ The Future of Shipping)

and the front line of the war against climate change.

5:40

S… Speaker 1 (5_3_Windship Technology _ The Future of Shipping)

That's the right direction.

5:41

S… Speaker 1 (5_3_Windship Technology _ The Future of Shipping)

Thank you.

5:41

S… Speaker 1 (5_3_Windship Technology _ The Future of Shipping)

All right.
