World’s first solar road opens in France: It’s ridiculously expensive

Kilometer-long road cost $5.2 million to build.

 

The world’s first solar highway has been opened in France, in the not-very-sunny village of Tourouvre au Perche in Normandy. The roadway is just one kilometre (0.6mi) long, but that still works out at 2,800 square metres of photovoltaic cells—enough, hopefully, to power the village’s street lights.

 

The road was built by Colas, a large Anglo-French construction company. Colas has apparently been working on its own solar road tech, called Wattway, for at least five years. Wattway has been tested in car parks, but this is the first time it has been used on an active road. There will now be a two-year test period, to see if Wattway can withstand the rigour of being pounded by thousands of cars and trucks per day, and whether it can actually provide a useful amount of electricity.

 

Usefulness aside, the main problem with constructing solar roads is their crippling cost. One of the main selling points of Wattway, according to Colas, is that each panel is just a few millimetres thick, and can thus be installed on top of an existing road, which in turn massively reduces construction costs. Having said that, the 1km road in Normandy cost €5 million (£4.3m) to build. And that’s for a single lane of a two-lane highway!

One of the Wattway panels up close.

 

Expanding that out to €10m per kilometre for a two-lane solar road, you’re looking at a total cost measured in billions or even trillions of pounds to cover a sizeable portion of a country’s roads with solar panels. France has over a million kilometres of roads; the US has over 6 million. And that’s not counting the larger highways with more than two lanes…

Fortunately, Ségolène Royal, France’s ecology minister, has a much more reasonable goal in mind: she would like to see solar roadways replace one kilometre of every 1000 in France. Again, assuming she means two-lane solar roads at around €10 million per kilometre, the total cost would be €10 billion—not bad, assuming the panels (and the accompany electrical system) don’t need regular maintenance, and that they produce enough electricity to be worth the much higher initial outlay.

Indeed, their questionable efficiency is one of the main reasons that more solar roads aren’t currently being built. Colas says that Wattway’s photovoltaic efficiency is 15 percent, which is pretty good (commercial panels that you might put on your roof are at about 20 percent). But that doesn’t take into account the fact that the solar panels are flat on the ground, rather than angled towards the sun’s trajectory, significantly reducing efficiency at higher latitudes. Heavy traffic could also block sunlight; as could snow, mud, and perhaps standing water after rain.

 

Back in 2014, a 70-metre solar bicycle path was built in the suburbs of Amsterdam in the Netherlands, at the utterly insane cost of €3 million. In its first year it produced about 3,000 kilowatt-hours (kWh) of electricity—enough to power an average home. At the current wholesale price in the UK (about £40 per megawatt-hour), that same €3 million would’ve bought you about 65,000,000 kilowatt-hours of electricity, enough to power about 21,000 homes for a year.

 

Obviously the maths are a bit better on the €5 million road in Normandy, but that’s still an awful lot of money to spend on powering the village’s (population ~3,300) street lights. The Wattway brochure suggests that 2,800 square metres of solar roadway ought to be able to power about 140 homes—about 420MWh per year. Though clearly, if they are just looking to power the village’s street lights, they’re not expecting anywhere near 420MWh in reality—perhaps due to the low amount of direct sunlight in Normandy.

Finally, because it’s Christmas and there’s no one in the office to stop me being mean, let’s talk about Solar Roadways, an Indiegogo project that raised a ridiculous sum of money ($2.2 million) back in 2014. That money, according to Solar Roadways, is being spent “on engineers to help us make a few needed tweaks in our product and streamline our process so that we could go from prototype to production.” Two years later, the first public installation of Solar Roadways is finally being constructed at a Route 66 welcome centre in Missouri.

 

According to the Missouri department of transport (MoDOT), the small 12ft-by-20ft patch of solar road will cost $100,000 to install. That works out at $416 per square foot—about $4,500 per square metre, or $11.6 billion per square mile. Scott Brusaw, founder of Solar Roadways, says there’s about 29,000 square miles of paved roads in the lower 48 US states, and he’d like to turn most of them into solar roads. He’ll need one hell of a Kickstarter to raise $330 trillion—16 times the US national debt—though.

 

Personally, I think Brusaw’s efforts would be better focused on just building a Dyson sphere and solving all of humanity’s energy issues in one fell swoop.

ElectroHydrostatic Actuation Offers Opportunities to Improve Hydraulic System Efficiencies

AEM discusses with Parker Hannifin’s Dale Vanderlaan the potential benefits of ElectroHydrostatic Acutation.

 

ElectroHydrostatic

 

Off-road industrial machines require multi-function implement operation with dynamic duty cycles. In many cases, machine implements demand short bursts of full engine power and brake dynamic loads requiring 50% or more of energy consumed. Many next-generation machines reduce energy loss and improve productivity by incorporating hybrid electric approaches with energy storage. An efficient implement solution enabling the hybrid electric approach is essential to achieve maximum improvement potential.

 

This topic will be discussed during the education session “Fundamentals of Hydraulic Systems” taking place during IFPE 2020. The Association of Equipment Manufacturers (AEM) recently spoke with the session’s presenter, Dale Vanderlaan, R&D engineering manager at Parker Hannifin, to discuss ElectroHydrostatic Actuation, its benefits, what attendees can expect him to share at IFPE 2020, and what key takeaways they’ll get from participating in his education session.

AEM: You are slated to speak at the upcoming IFPE 2020 show in Las Vegas on the topic of hydraulic system fundamentals and, more specifically, ElectroHydrostatic Actuation. What are some benefits that can be gained by companies who employ ElectroHydrostatic Actuation, especially as it compares to some of the other technologies out there?

Dale Vanderlaan: ElectroHydrostatic Actuation is an extremely flexible solution, focused on improving hydraulic system efficiencies. Next generation off-road mobile machines will be electrically powered. Simply powering an existing pump and hydraulic system with a battery does not address the efficiency of the hydraulic system and will require a large battery which takes up a lot of space and can be costly.

By taking an ElectroHydrostatic approach to improve system efficiency, existing cylinders and system infrastructure can be used. Electromechanical types of systems are not practical, so we know that hydraulic cylinders will not be replaced anytime soon. Not having to change cylinder technology is a significant benefit.

Addressing valve loss within a system is also key to improving efficiency. Changing the traditional hydraulic distribution method with a power-on-demand approach can be very beneficial with certain functions. ElectroHydrostatic Actuation does not require a control valve to control the actuator, which eliminates the valve loss for a particular function. If applied to more than one function, additional valve loss can be eliminated.

The flexibility of ElectroHydrostatic Actuation should not be minimized. Being able to apply it to the right need within an application is a key benefit. The ability to distribute power though hydraulics is a definite advantage over an electromechanical approach.

And, finally ElectroHydrostatic Actuation enables energy recovery and it can be accomplished fairly easily in applications where it makes sense. Energy can be recovered and used right away or stored in the battery.

AEM: Do you feel the industry – at least in general – widely understands the benefits that can be gained from ElectroHydrostatic Actuation?

Dale Vanderlaan: Yes, in general, I think that the benefits of ElectroHydrostatic Actuation are understood in the industry. However, I don’t think that the flexibility of the approach is well understood. It does not have to be an all or nothing type of decision, there isn’t a need to add complexity and cost to have a dedicated motor pump for every possible function. It is important to take advantage of the system’s flexibility and target ElectroHydrostatic Actuation to a function where it makes sense.

AEM: What are some frequently asked questions you hear from manufacturers at this point in time about the technology?

Dale Vanderlaan: Performance and cost are the two main areas of concern from manufacturers. The benefits of the technology need to be greater than the cost, and that really comes down to targeting a solution and picking the right technology for an application.

First and foremost, manufacturers want to be sure that the performance and response of a traditional approach are not degraded. I believe that you can get similar performance for mobile applications and often better performance. The key is to understand what the requirements are and work to select the right technology to accomplish the goals.

There are usually questions related to noise as well. When vehicles are powered with batteries, they operate with less noise. Manufacturers want to understand the impact on noise reductions.

AEM: What knowledge do you want attendees of your session at IFPE 2020 to walk away with and be able to implement at their own companies?

Dale Vanderlaan: Electrification is happening at all sorts of levels and adoption rates. It’s about getting ready for it, since it’s a matter of when, not if. Smaller machines are already battery powered. As battery technology improves it will be an enabler to move to the ultimate goal of battery-operated large off-road machines.

Because of this, it is important to move into this next-generation hydraulic system approach. We are seeing one motor driving exiting pump and system, but the real benefits are to be gained by making hydraulic systems more efficient. Parker is the leader in motion and control technology, and has demonstrated this in many applications including aerospace. There are significant improvements when Electrohydraulic Actuation are implemented.
