There’s a better answer than electric cars

Erich Sixt, chairman and chief executive officer of the Pullach, Germany-based global car rental company that bears his family’s name, recently described electric cars as a “costly political error” given their still inferior range, long charging times and the huge investment necessary to expand the charging infrastructure. It may have been a self-serving statement, but he may also well be right: If a paper correctly estimates cost of extracting carbon dioxide from air, regulators could do better to concentrate on that technology rather than on forcing vehicle electrification.
Carbon Engineering is a company co-founded by Harvard physicist David Keith and funded, among others, by Microsoft founder Bill Gates. Since 2015, the firm has been running a CO2 extraction plant in Canada, testing out a technology that was until recently rejected as too costly. Keith and his collaborators, who wrote the paper, have used an independent cost assessment to calculate that using the process they developed allows capture of a metric ton of carbon dioxide at the cost of $94 to $232, depending on variable costs such as price of natural gas.
That is far lower than previous estimates for the technology, ranging from $550 to $1,300 per ton. The paper’s authors explain that the reduction comes from simply using industrial equipment already available on the market without much customization, a strategy they put in place at the Canadian plant.
At Keith’s prices, investing in CO2 capture can be a better idea both for consumers and for the environment than car electrification. According to the International Energy Agency, increasing the number of electric cars on the road from the current 2 million to 280 million by 2040 will only displace 1 percent of the expected global CO2 emissions, largely because other demand for carbon-based energy, including from planes and ships, will push emissions up – and because electricity to power the giant electric vehicle fleet won’t come entirely from clean sources. To achieve this unimpressive result, carmakers have already pledged some $90 billion in EV investment, and that’s not counting the cost of the ubiquitous infrastructure necessary to give EVs mass appeal, the investment needed to expand power generation and network capacity and the government subsidies to electric car buyers.
Since late last year, Carbon Engineering’s plant has been producing fuel from CO2 it extracts by combining it with hydrogen. The fuel is compatible with current internal combustion engines, so there’s no need for carmakers to invest in different technology. Since burning synthetic fuel can only release as much CO2 as was used in its production, the whole cycle is pretty much carbon-neutral.
Keith calculates that at scale, his technology can produce fuel at $1 a liter ($3.79 per gallon) – significantly higher than the current wholesale prices. There’s no question that going over from fossil fuel to the synthetic liquids would need to be subsidized by environmentally-friendly governments, but such subsidies have a distinct advantage over incentives for EV owners and investment in parallel infrastructure: Nothing will need to change for the enormous existing fleet of cars, about 1 billion of them. Existing gas stations will be able to handle the new liquids just as they do fossil fuel, too.
Obviously, producing enough synthetic fuel to reduce emissions significantly will require lots of extraction capacity. According to the paper, building a plant capable of capturing 980,000 tons of CO2 a year requires some $1.1 billion of capital investment, which could be brought down to $780 million if construction begins at scale. To cut the CO2 emissions predicted by the IEA for 2040 by 1 percent, or by 357 million tons, would require $284 billion at Keith’s estimated prices. That number, however, is comparable with the total investment necessary to go over to electric cars. Besides, there are other carbon capture technologies that can be deployed directly at industrial facilities that use fossil fuels; developing them at scale could lower the required investment.
None of this is to say electric cars shouldn’t be developed or sold. There are plenty of true believers who will buy them, probably enough to support some production and investment. It’s just that governments, which have recently latched on to vehicle electrification as compulsory, and even begun putting out competing dates for their future bans on the sales of cars with internal combustion engines, may actually be wrong-headed.
There’s no pressing need for regulators to rush into embracing the imperfect technology behind today’s EVs and pushing it on manufacturers and consumers. Other technology exists that could use the regulatory attention and at least some of the government funds going into EV promotion. Promoting its development won’t necessarily pay off, but it could well lead to better, less traumatic outcomes for an important established industry and for a billion people who use its products.
