Vive la France - Sustainability Leadership

On May 14th 2010, the UK's Prime Minister, David Cameron said "I want us to be the greenest government ever - a very simple ambition and one that I’m absolutely committed to achieving"... 

In 2016, as UK citizens consider their membership of the EU, the news is full of debate about the relative merits of staying or leaving. Whatever the decision, our friends in France can not only teach us about great cooking, but also sustainability leadership. In fact, they have been delivering innovative business models and regulation which has the potential to nudge the nation to be a global sustainability leader. Let's explore some of their innovations in a little bit more detail...

Mobility

Air pollution is becoming a huge problem in large cities (London is not an exception, with an estimated 9,500 premature deaths each year), and in Paris in May 2014, drastic traffic restrictions were imposed.  There's more need than ever, then, for new mobility solutions to be promoted.

Cycle hire

Long before London's cycle hire scheme was launched, back in 2007, Paris introduced their Vélib' cycle hire scheme.  With over 20,000 cycles and more than 1,200 stations, it's a sustainable and fit way to travel within the arrondissements of Paris.

Electric Moped Hire

Soon, there will be two-wheeled collaborative consumption competition, when Cityscoot [in French] launches, an electric moped scheme.  Available to riders over the age of 20 with a valid moped licence, they will be bookable from a smartphone app for €3/15 minutes.

Peugeot Mu Vehicle Hire

Before many car manufacturers recognised the upcoming threat of 'access over ownership' business models, Peugeot launched Mu, allowing users to rent a car, moped or even van, depending on their needs.  Of course, their electric vehicles are available to rent as part of the scheme (e.g. iOn).  The scheme also launched in the UK back in 2010, as well as Germany, Spain and Italy.

Electric Vehicles

It's not just Peugeot who have 100% electric cars available, Renault has a range of vans (Kangoo Z.E.), as well as its tiny Twizy and Zoe, and Citroën (part of the PSA Peugeot Citroën group) has something to offer too with the C-Zero.

And of course, with a significant amount of France's electricity generation coming from nuclear (check out this great site to see the energy mix), there's less of an issue of fossil-fuel power plants polluting the environment.

Finally, Renault have announced a partnership with Connected Energy, where their E-STOR proposition uses batteries from Renault cars to support storage from intermittent renewable sources, or for EV charging solutions.
Solar Roads

France hasn't stopped with the vehicles on the roads, it's even considering the roads themselves.  Colas has introduced Wattway, and there's now a plan for 1000km of roads to be made of solar panels across the country.

Food waste

Food waste is a huge problem at all points along the supply chain from farmer's field, through to the fridge in the customer's home.  France is looking to tackle the problem between the two, banning supermarkets from throwing-away or spoiling food.

Solar / green rooftops



France has another leading policy with new rooftops in commercial zones around France, which must now be built with solar panels, or a 'green roof' covering part of the roof.

Grenelle II - Sustainability Reporting

In April 2012, France decreed that companies must report according to article 225 of law No. 2010-788, or 'Grenelle II', as it's known.  Courtesy of a helpful description from Alcatel-Lucent, it essentially means that corporates must produce an independently-verified report on the environmental, social and societal aspects of their business operations, alongside the financial results.

Corporate Leadership

As well as an active automotive sector referenced above, some other large French corporations are making positive steps to a more sustainable society.

Axa

Axa is a French insurance company, as has woken-up to the fact that climate change poses a fundamental threat to its customers, and therefore it's viability as a sustainable organisation.  It has several impressive initiatives underway:

Veolia

Veolia has long seen the business opportunities around the 'circular economy', and has successfully reinvented itself as a 'resource management' services provider.  It's a member of the Ellen MacArtthur Foundation, and is helping push the circular economy agenda.  One such initiative, is where they have created a recycling loop for small electrical appliances, in partnership with Groupe SEB and Eco-systèmes.


BNP Paribas

Innovative startup, Qarnot Computing, has developed a distributed data centre solution, where schools and offices around Paris can host servers, which are then used to heat their premises, for free, using excess heat as radiators.  BNP Paribas have agreed that 5% of its computing power to support risk calculations will be used via this platform, reducing their carbon emissions required to support this computing effort by 75% (mainly due to reduced cooling needs).

Tesla Powerwall - Energy Storage

Tesla have launched their new internet-enabled energy storage solution, Powerwall.  Aimed at domestic customers, at launch in the US, there is a 10 kWh version for $3,500, or a 7 kWh model for $3,000 (costs exclude the inverter and installation).

*June 10th 2015 update* Tesla have announced that the continuous power from the batteries will be increased from 2.0kW to 5kW, with peak increased from 3.3kW to 7kW. Additionally, it is reported that 38,000 orders were taken within the first week of launch for the Powerwall.

Tesla's $5bn Gigafactory in Nevada, which is aiming to produce 500,000 batteries a year by 2020 means the production facility scale will be there to support the expected demand.  And with Tesla’s CEO, Elon Musk, as Chairman of his cousin’s business SolarCity (the leading full-service solar company in the US), there's a natural route to market.

The solution is also scalable for enterprise and network applications. This is called the Powerpack, and is scalable in 100kWh blocks, up to 10MWh.

Energy storage can help smooth the inherent intermittency of solar energy generation, so has the potential to offer a proposition which could make households effectively become self-sufficient for energy (off-grid).

It should also encourage the uptake of electric vehicles and electrification of heat, helping decarbonise society's energy use.

Hydrogen - an answer to pollution in cities?

For automotive transport, hydrogen power is one possible answer to the huge challenge of cities looking to control their pollution levels - producing tailpipe emissions of water.  But, other than a couple of small scale pilots, the odd bus and taxi funded by a couple of technology grants, the technology isn't going anywhere is it?  Well, car manufacturers seem to think differently, with a recent push for production-ready models being introduced.  In parallel to this, researchers have found potential for the 'wonder material' graphene to potentially support hydrogen fuel cell development.

Below, I'll introduce a selection of hydrogen cars, a reference to public transport solutions, the refuelling infrastructure, and where the hydrogen comes from.



The Car's the Star...

Here's a selection of cars which are powered by Hydrogen now (in alphabetical order).  Some were launched in the last five years, but interestingly,  recent motor shows (especially LA) have seen a bit of a proliferation, which is encouraging that R&D spend is being spent on commercialising the technology.

Most cars have carbon-fibre reinforced hydrogen storage tanks onboard (refilled in as little as 3 minutes).  The hydrogen is then mixed with air (oxygen specifically) in a fuel cell (the clever bit with a catalyst), which generates energy to power an electric motor to the drivetrain.  Additional batteries may provide the ability to capture the energy from braking.

Audi A7 h-Tron

Toyota Mirai



Toyota Mirai
In 1997, Toyota changed the rules of the game, by introducing the Prius.  Well, it's at it again, so we should probably take this pretty seriously - the Mirai.

To attract motorists on the West Coast of the US, they have developed a pretty impressive microsite - check it out here.

*UPDATE - Jan 2015* Toyota have opened their fuel-cell patents to others


Volkswagen Golf SportWagen HyMotion

  • Uses a low-temperature proton exchange membrane (LT-PEM) - presumably very similar to their sister group Audi use in the A7 h-tron, above
Some more details from Autocar here.

Volvo

Back in 2010, Volvo announced work to develop the C30 DRIVe Electric to incorporate a hydrogen fuel cell, to help extend the range.

Public Transport is joining in...


Taxi


For London 2012 Olympics, five iconic black cabs were launched, powered by hydrogen.  Here's a (not that exciting!) video showing them:






They were refuelled at Heathrow, and used to take dignitaries into London.  Apparently, they have a range of 250mph, and one has been as fast as 95mph on a test track.


Bus

Transport for London (TfL) runs a fleet of 8 hydrogen buses on its tourist-friendly RV1 bus route:


RV1 Hydrogen Bus, London

More information can be found here from the 2010 press release.  This of course misses the subsequent news that the buses were temporarily withdrawn from the route during the London 2012 Olympics, as part of a hazardous materials ban.


Refuelling Infrastructure

Of course, having hydrogen vehicles is only part of the puzzle, you also need viable options to refuel them (much like the current 'range anxiety' issues with EVs).  For the UK though, there is some good progress:







*UPDATE - January 2015* In Japan, Tokyo's making investments in hydrogen infrastructure ahead of the 2020 Olympics, in helping reduce its reliance on Nuclear.  As reported by Bloomberg, they are hoping to build 35 refueling stations, and have 6000 hydrogen cars on the road by then.


But where does the Hydrogen come from?

Having tailpipe emissions of just water is pretty attractive, especially in cities like London, which are under incredible pressure to reduce their emissions.  However, it's important that any environmental impact isn't just externalised somewhere else, namely at the point of hydrogen manufacture.

Hydrogen is of course everywhere, in fact it's earth's most abundant element.  The snag is that it tends to hang-around pretty closely with its other element friends, and it takes a fair bit of energy to separate them.  So, the trick is to be able to isolate it, and store it safely.  There are a few options (taken from Toyota's helpful site):

  • Gasification - high temperature organic waste
  • Steam reforming - high temperature reaction between methane (natural gas). and steam
  • Electrolysis - passing current through water, to separate hydrogen and oxygen

Some of these sources aren't free of emissions, so there needs to be an ongoing push to source the energy needed from low-carbon sources, else we won't have delivered a net environmental benefit.  And on that note, it's worth celebrating a UK first, courtesy of Honda, who have recently launched a solar-powered hydrogen production and refuelling facility on their Swindon site - what an incredible achievement!
