Sustainable Mobility - What's Next?

Regular readers of my blog or my Twitter feed (@UK_Richard) will know that I've been writing sustainability updates on mobility for several years.  These have included briefs on the global motor shows, reflections on emerging mobility business models, and the inevitable resurgence of cycling in city centres. It's been fascinating to document some of the changes which have happened, including:
  • Hybrid powertrains being an option in almost every model from each manufacturer
  • Disruptive EV-only start-ups providing a wake-up call to the incumbent OEMs caught napping
Tesla Model X, a pure-electric SUV

  • 'Dieselgate' and the accompanying toxic air pollution acting as a 'burning platform' for regulatory change, and even civil unrest
  • The pace of autonomous vehicle technology raising fundamental questions about the role of the driver (not to mention liabilities and the insurance industry) - but potentially providing step change improvements in safety
  • Hydrogen fuel cells refusing to disappear as a viable alternative to lithium-ion batteries, but with unanswered questions about the viability (and sustainability) of a distributed refuelling infrastructure

  • The implication on the electricity grid with EVs acting as portable energy storage, whilst often needing to charge at the same time, during the evening peak
  • Cycle sharing schemes, including the introduction of dockless ones, and e-Bikes


  • Car sharing, evolving into 'Mobility as a Service' (MaaS) models, supporting multi-modal journeys with single payment gateways and routing, allowing train operators to extend their reach beyond the platform
  • Ride hailing business models like Uber, reinforcing the doubts the younger generation have about whether car ownership is even desirable anymore
  • Train electrification and growth of light-rail, including use of batteries, where line electrification isn't economical, or hydrogen fuel-cell powered trains
  • RailBaar static train battery charging
Time to gaze into the crystal ball to outline some of the changes we might expect to see in the next 5-10 years.  In sustainability, experience would suggest that for mass adoption, a few factors need to work together - personal aspiration, the right regulatory framework, cost parity, technology availability, social acceptance, etc.  But it's clear that in the mobility sector, the planets are aligning nicely to allow us to be very optimistic about the future.

Vehicle Design
  • To-date, the majority of EVs have replicated existing form factors (SUVs, saloons, etc.).  However, I expect we'll see three emerging form factors start to gain more traction:
    • Micro-delivery vehicles. Competing perhaps with air-borne drones and pedal-powered solutions, Small form-factor delivery EVs will start to gain market share in busy urban cities.  Deutsche Post's spin-off StreetScooter is a great example.

StreetScooter
    • As on-demand ride-sharing grows in cities, I'm expecting something with more seats than a car, but less than a bus to be the perfect compromise, much like what CityMapper are trialling.  Efficiently and predictably getting people to their destinations, public transport will become desirable again!

    • Finally, as cities become ever louder voices in supporting innovative mobility solutions to combat air pollution, I'd be surprised if we don't start to see a lot more tram systems being built in cities, and perhaps even the trolleybus will return?
  • Modularity of vehicle design seems likely, allowing a vehicle to be 'right-sized' for a particular time of day. However, this will take a few different forms:
    • Allow the physical joining or sensor-based 'platooning' of vehicles travelling on the same route to travel in a 'chain', 'disconnecting' as they branch-off to their final destination
    • An individual vehicle made of modular core components, allowing for example, an extra row of seats, or additional storage to be added
  • Autonomous vehicles are coming, with most manufacturers promising at least one model by 2020/21.  I am expecting a split though:
    • A.) the technology and user experience that allows passengers to avoid driving all together, perhaps exploiting super-fast internet access to watch entertainment, do work, or even keep fit on the move
    • B.) less intrusive autonomous driving capabilities, which do not detract from the enjoyment of driving, but enhance it, whilst providing the option to communicate with other autonomous vehicles and improve occupant safety
  • There's rightly a focus on exhaust emissions from vehicles, and of course EV powertrains will prevent that.  However, one of the 'elephants in the room' is that there's significant energy involved in manufacturing the vehicle in the first place.  As society moves from individual ownership to shared fleets, we should see increasing focus on extending the life, durability and maintenance of vehicles, with
    • Sensors to monitor all aspects of vehicle health remotely, to support preventative maintenance
    • Modularity / ease of disassembly to allow damaged components to be swapped-out
    • Simple battery swap-outs
    • Use of remanufactured parts, whilst retaining (or exceeding) existing warranties
    • Safety features meaning a step-change reduction in accidents
Mobility Ecosystem (including Vehicle to Infrastructure - V2I)

I expect to see a significant increase in the ways vehicles interact with the environment within which they are operating.  There are some barriers to this, including the need for common standards, data privacy and cyber-security, but some concepts are very likely to gain traction, as the 'Internet of Things' (IoT) starts to create the 'smart city' of the future:


  • Traffic signal integration. Essentially an evolution of existing sensors which can detect traffic queuing at red lights, interaction between the approaching vehicle and lights will help smooth traffic through an area, much like what Audi have trialled in the US. Prioritisation could be made to the emergency services, or perhaps even those that pay a premium?
Audi's V2I traffic-light integration
  • Street light integration.  Even with LED luminaries, street light costs are significant - yet often unused roads are being lit.  It's straightforward to detect upcoming traffic (or pedestrians) and turn on lights, only when required.
  • Street light EV charging. With the need for a significant rollout of public EV charging points, allowing vehicles to plug into street lights seems like a pragmatic approach to take.

  • Smart parking.  As a precursor to autonomous vehicles being able to park themselves to charge, we are going to see a proliferation of 'smart parking' solutions. These will help drivers find, reserve and pay for parking spaces, with costs determined by factors like day of week, time, and local traffic and weather conditions.  As around 30% of drivers in urban areas are actively looking for a parking space, this has a huge opportunity to reduce congestion and air pollution.  A virtuous circle could exist where redundant car parks could be converted to green spaces, helping improve air quality further.
  • Vehicle to Home (V2H) / Grid (V2G).  A charged Electric Vehicle is portable energy storage - potentially an important asset to the local electricity grid operator, especially when aggregated across a fleet.  We will start to see incumbent energy suppliers and new aggregators offering incentives for vehicles to be charged (or not charged) at certain locations and times.  And within the home too, a connected EV could act as battery storage to store excess generation from solar panels, and conversely used to power the home at night.
  • Dynamic Wireless EV Charging.  After a recent successful trial by Renault and Qualcomm, we may start to see charging of electric vehicles whilst they are travelling, eliminating the need for static EV charging points.  More generally, inductive charging will grow, removing the hassle of managing burdensome EV cables
  • Dynamic Road Pricing.  Road charging today is relatively crude, either tolls on stretches of road, or charging zones.  In the near future, we will start to see more innovative charging models, based on other factors, such as the number of occupants, which powertrain mode is used, local air quality, etc.
  • Smart-ready Roads.  Autonomous vehicle technology relies on clear road markings and signs.  We are starting to see trials of smarter roads, surely an important prerequisite to facilitate the safe transition to fully autonomous fleets.
  • Inter-modal Integration. With superfast connectivity and big-data solutions, there isn't an excuse now for better integration between different modes of transport. Expect to see boundaries continuing to blur between public and private transport, with incumbents and start-ups offering a seamless experience between rail, road and river, with integrated ticketing systems, timetables (or on-demand), and route optimisation. Deutshe Bahn are looking at providing on-demand last-mile autonomous vehicle pickups from train stations, for example.


Regulation

Finally, it's worth noting the local, regional and national governments, law-enforcement agencies and standards bodies will have an important role to support this rapid change. The following areas will be of particular interest:

  • Managing the transition away from diesel (and perhaps petrol too), with changes required to support scrappage of vehicles, vehicle excise duty, support for dwindling fuel retail outlets, etc.
  • Ensuring compatibility and quality standards for EV charging points
  • 'Rules' for autonomous vehicles, e.g. how should they behave given the choice between crashing into another car, or hitting a pedestrian?
  • How best the insurance industry should evolve to support autonomous vehicles and sharing business models
  • Cyber-security and protection of personal data
  • Protecting the electricity distribution grid from additional supply and demand spikes caused by EV charging and V2G/V2H models
  • Supporting peer-to-peer EV chargepoint models, considering safety of vehicles and users
  • Competition rules, as incumbent vehicle manufacturers, and energy suppliers/distributors may exploit a potentially dominant position
  • EV battery re-use and ultimate disposal
  • Vehicle design and manufacturing standards to support the circular economy, including quality of remanufactured parts
  • Protecting customers if finance houses (e.g. from car manufacturers) have over-exposed themselves to risk with diesel depreciation (most private vehicles are bought on PCP in the UK)
  • Regulation and standards to support new 'smart city' solutions, like dynamic road pricing, smart parking and traffic light integration
  • The decarbonisation of public transport, and allowing new service entrants to challenge the incumbents with innovation business models (i.e. opening-up monopolistic routes to competition)
  • Support for hydrogen refuelling infrastructure
  • Further promotion of safer cycling
  • Standards for inter-modal ticketing solutions
  • Skills training for professional drivers, who may see their roles being taken-over by autonomous vehicles
  • Managing our skies (and underground?) - supporting drones for deliveries and movement of people



To summarise then, we're about to enter an unparalleled level of change in how people and goods move between places.  If we get this right, we'll be moving around in a much cleaner environment, more quickly arriving at our destination, and turning wasteful commute time into productive, creative, social experiences.  Exciting times indeed...

Vehicles powering the future

Since the 'Benz Patent Motorwagen' was launched in 1879, cars have evolved into technological marvels, with new features like electric powertrains and autonomous driving capabilities pushing our expectations into the realms of science fiction.  Additionally, new ownership models like car-sharing mean the once-important aspiration of owning a car has evolved into Generation Y just wanting to access one.

 


However, to-date, the car fundamentally does exactly what the horse and cart did before it - to transport people (and luggage) from A to B.  But is that about to change, with in-car battery storage introducing new propositions and business models?

This week, in partnership with ENEL, Nissan introduced smart grid trials, with the car being an 'energy hub' for the home. 



The concept is straightforward:
  • 'Vehicle to Home' (V2H) allows energy stored in the car battery to be used to power the home - useful when buying electricity directly from the grid may be more expensive, e.g. at peak times
  • 'Vehicle to Grid' (V2G) allows the car owner to sell excess stored energy from the car battery back to the grid, helping to flatten peaks and/or meet short-term energy demand
 

A video from Nissan describes a little more about the concept:



Other energy storage options can be found in static battery solutions much like the recent Tesla Powerwall and a similar approach from Daimler, but of course these can't also transport you to difference places!

Other manufacturers are investing in similar propositions (some using hydrogen fuel cells), with several concepts unveiled at the 44th Tokyo Motor Show in October 2015

 


Models shown above from Toyota, Honda and Mitsubishi respectively.

There are two propositions which seem to make sense to exploit this technology - it will be interesting to see how soon they may appear...

Household energy

In the most basic model, a single household uses their charged car when at home to provide additional energy for their home (V2H), reducing the reliance on peak grid electricity (and avoiding potential high-carbon emitting loads like backup diesel generators).  This can be more intelligent still if the household can also generate their own electricity, e.g. via solar panels... potentially getting close to being 'off grid'.  Excess energy can be sold to the grid (V2G).

Community/collective energy

The proposition above may be attractive enough to households to reverse the trend of declining car ownership, but perhaps that's an irreversible trend.  If so, there may be some innovative business models which emerge, using a fleet of vehicles, where households do not own a vehicle:
  • A community own a fleet of vehicles, leasing vehicles to households/businesses, or providing a car-sharing pool.  This consolidated fleet of batteries together provide a 'virtual distributed energy storage solution'
  • The concept could be extended to public transport too, as electrification emerges as a viable powertrain in buses
  • Combined with solar arrays on a mixture of residential, commercial and industrial premises, a 'portfolio' effect within the geographical community can start to automatically match energy demand with supply, perhaps setting dynamic price signals to nudge behaviours to optimise the system.  Excess energy would be sold to the 'national grid', or neighbouring communities
  • As autonomous vehicles become a reality, could a fleet of driverless taxis spend part of their day ferrying passengers around a city, and during 'downtime', find a local dock to either recharge or sell some of the stored energy to the grid, using predictive 'big data' analysis to be positioned for likely customer pick-ups?

Of course there are a significant number of barriers to overcome:
  • Cost - both Capex and Opex
  • Behaviour change - for households to be willing to share data, to trust the system will work, and to nudge their energy usage to fit the most efficient model
  • Battery density and cycling performance
  • The need for a 'smart grid' (including metering and billing platforms) to be able to manage a hugely complex and dynamic distributed energy lifeform
  • Regulation, with some incumbent parties potentially lobbying against progress
  • Insurance liabilities
  • Operations - servicing, cleaning, asset protection, infrastructure reliability, health & safety, etc. 
...but there are also a large number of parties who may be interested to making it successful, as they want to diversify, or see their traditional revenues/funding decline:
  • Car manufacturers
  • Energy retailers or network operators
  • Data/information firms (Google)
  • Trusted retailers (IKEA?)
  • Cities, or local councils
  • Existing vehicle fleet owner (courier service)

Do you think any of these concepts could become a commercial reality, at scale?

*UPDATE* In fact, BMW are currently running a trial in the US, with 100 BMW i3 drivers, and their utility, PG&E.   As part of the BMW i Charge Forward programme, BMWi will be able to remotely delay the charging of EVs by up to an hour, to better match the grid requirements, whilst allowing the driver to override/opt-out if required.

44th Tokyo Motor Show - Highlights

The Tokyo Motor Show is an opportunity for Japanese manufacturers to reveal their latest production-ready and concept vehicles.  Below is a summary of the vehicles which have sustainability in mind, with some noticeable introductions of 'Vehicle to Home' (V2H) energy systems. Amongst other applications, these can provide short-term emergency power - something Japan is very sensitive to, following the 2011 tsunami and Fukushima disaster.


Toyota FCV Plus (2015) - in 'power sharing' mode


Honda Clarity FCV

Honda's investment in hydrogen energy continues, with the Clarity saloon, the first to incorporate the entire fuel-cell powertrain in the space normally occupied by the engine and transmission.  It has a cruising range of 700km, and the Japanese version of the model can act as a mobile power plant, with an external power feeding inverter.


Honda FCV

Lexus LF-FC

Lexus have introduced the Lexus LF-FC, a fuel-cell powered flagship concept.  Here are the details of the powertrain:

"At the heart of the LF-FC is a high output fuel cell power system that energizes the rear wheels, and also sends power to two in-wheel motors in the front, making the LF-FC all-wheel-drive. This innovative drive system allows precise torque distribution control between the front and rear wheels, giving the full-size sedan exceptional dynamic handling and superior road stability. The strategic placement of the fuel-cell stack at the rear of the vehicle, power control unit at the front and T-formation configured hydrogen fuel tanks result in front and rear weight distribution optimal for a sporty sedan."

Toyota FCV Plus

Hydrogen power is currently the underdog to be the dominant fuel source for mobility solutions in the future, but some manufacturers are investing huge amounts in the technology - see my recent blog to read about some examples (including the Mirai from Toyota).  Toyota has now taken this one step further, and sees hydrogen cars as being an energy source to share with the community.  Specifically, as well as its own hydrogen tank, it can also generate electricity from an external hydrogen source, allowing the power generated to be available at home, work, etc.
