Electric Vehicles are the Future if We Can Let Go of the Past

May 13, 2021

By Rowen Huxtable

A worldwide transition away from internal combustion (IC) vehicles to electric vehicles (EV) and fuel cell vehicles (FCV) is under way. Australia will be better off in many ways from this transition but the government’s approach will determine whether we maximise the benefit or whether we miss out.

In 2019-2020 Australia spent about $22 billion on imported refined petroleum. That’s about twice the total export value of the beef industry and nearly equal to our export income from gold mining. Replacing imported energy with energy made in Australia would give us a major wealth boost. If we, as farmers say, used electric vehicles with energy generated on the farm, the money would stay on the farm.

For vehicle users, electricity is much cheaper than petrol or diesel. And EVs have a much lower moving part count so they require less maintenance.

Petroleum import dependence is not just a major cost. It is a major risk. The imports come from politically unstable regions through seas that are increasingly contested. In April 2021, Australia notionally had 68 days worth of crude oil to hand, according to the International Energy Agency. This capacity includes the recent government purchase of about five days’ worth of supply from the USA – now stored in Texas – and crude oil on ships or in refineries in Asia.

It would be unwise to count on this overseas oil as being available to Australia in a crisis. Even if crude oil gets here, Australia has limited refining capacity. Australia’s refineries are small and uneconomic. Twenty years ago we had eight refineries. Since then six have closed and the remaining two are at risk of closure.

The upshot is that Australia has only 30 days of petrol and jet fuel and 20 days of diesel to deliver food to people in the event of a disruption.

A distributed renewable energy grid is a far more secure way of powering our vehicles.

Petroleum is not the only risk. Currently, IC vehicles are made by the ‘A’ team on longer production runs than EVs or FCVs. So they are cheaper. But this will change and experience in other technology areas shows that the relative price change can happen very quickly.

Ford, GM, Mazda, Mitsubishi, Volkswagen and Toyota are all planning to phase out ICs. The USA and Europe have aggressive plans to phase out IC vehicles sales. We risk being unprepared and forced to buy expensive legacy vehicles made by the ‘B’ team.

Lithium supply and battery recycling will be an issue for the EV industry but this is an opportunity for Australia not a showstopper. Australia has the second largest lithium deposits in the world. So Australia is well placed to manufacture batteries. Lithium recycling technology exists now and will improve. Lithium recycling does take energy but Australia has abundant energy.

Fuel cell vehicles (FCVs) are an alternative to batteries. An FCV has a hydrogen tank, a fuel cell to get energy from the hydrogen, and an electric motor and controller. The worldwide FCV industry is expected to grow by over 11 per cent per annum over the next 5 years with the strongest growth in Korea, China and Japan.

Technology to make bulk hydrogen from seawater using solar power is in its infancy but will develop rapidly due to worldwide demand for low emissions energy. Australia, with its abundant solar energy, ready access to seawater and plenty of space to build production plants, could be the best placed country in the world to make hydrogen.

Australia has a fledgling EV and FCV industry. H2X is planning to manufacture FCV tractors and cars in Wollongong. Ace and Uniti are planning electric van and car manufacture in Adelaide. Nexport is setting up an electric bus manufacturing facility in Moss Vale. FonzMoto and Savic are advertising Australian-made electric motorbikes. The world vehicle industry is being disrupted and we will never have a better chance to get into the market.

In Australia, there are over 700 deaths per annum caused by particulates, ozone and nitric oxide emitted by IC vehicles. Traffic noise has been shown to affect children’s learning ability and increase the rate of heart attack.

The transition away from IC vehicles should be done in a smart way, picking the lowest hanging fruit first. Sure, if you want to tow your boat across the Nullarbor you might need an IC vehicle for a while. But most vehicle trips are short hauls to work and to the shops. Cars at the office or shopping centre could charge while the car is parked. Mining companies could charge up their vehicles at the mine. Early morning delivery vans could charge once they get back to the depot.

Transitioning away from IC vehicles means that Australia could become a leading world supplier of hydrogen, a leading purveyor of recycling technology, a leading battery manufacturer and a vehicle manufacturer. It could be a more secure, wealthier and healthier country.

To maximise the benefit, the government needs to support the new industries and technologies involved rather than clinging to fossil fuel. And the government needs to lead and communicate properly. The voters deserve better than mindless slogans about weekends being ruined.

    1. It seems our electoral cycle and a stubborn conservative bent is blunting an overarching community desire, especially amongst the young.to seek the shift to renewable energy replacing fossil fuel-use; to help us mitigate man's accentuation of detrimental climate changes.
      I.C. Government-owned vehicles should be phased out in not less than 5 years and incentivised and subsidies used to assist strong Renewable's start-ups,
      especially aimed at transport.
      Home Solar Power should be looped locally with local battery storage utilizing economies of scales and separated from industry-use power accept where access capacity overflow assists industry.
      Pilbara NSW fracking and the attendant gas pipeline must be scrapped for it's breath-taking environmental vandalism and rural/human health destruction/risks.

    2. It concerns me how little fuel we had in store and given the Pandemic experience one would hope this would compel us to become more resilient n protecting a good number of things here.
