We hardly ever talk about how much land we sacrifice just to slightly water down fossil fuel.

In the United States, tens of millions of acres of farmland are used to grow corn for ethanol. That corn is not there to feed people. It mostly exists so that roughly ten percent of the gasoline in a car tank can be biological instead of fossil.

If you take that same land and cover it with solar panels and some wind turbines, the picture changes completely. On the same area, you could generate many times more usable energy than you get from the ethanol made from the corn. And if you use this clean electricity to split water into hydrogen, you end up with far more chemical energy in hydrogen than in the ethanol that is being blended into fuel today.

A Simple Thought Experiment

Imagine this. We stop growing corn for ethanol. We replace combustion engines with engines that run on hydrogen. Then we use the freed farmland for solar and wind and feed that power into electrolysis. The result is that you can, in principle, supply something close to the entire current energy demand of the transport sector in the form of hydrogen fuel, without asking people to drive less.

Where Policy Went Wrong

While this is technically possible, politics has gone in a very different direction. In many countries, including Germany, governments heavily pushed battery cars for a while with subsidies and marketing, but only a small part of the population really switched. Then those subsidies were cut back again, and now most of what is left are plans to ban combustion engines at some point in the future. Instead of honestly admitting that battery cars are still not where they need to be and looking seriously at better fitting technologies like hydrogen, the focus just moved from support to pressure.

The Problem With Battery Cars

Personally, I do not see battery cars as a good solution right now. Batteries are heavy, expensive, slow to recharge, and they wear out over time, so the car keeps losing range and value. A used battery car is a risky purchase because the most important and most expensive component, the battery, can already be half gone. It is inconvenient to depend on charging infrastructure that is not equally available to everyone, and even as range slowly improves, long charging times remain a big problem.

Why Hydrogen Fits Better

Hydrogen cars can use electric motors powered by fuel cells, so they keep the strong efficiency and instant torque of electric drive, but with fast refueling and long range much closer to what people expect from combustion cars. For ordinary drivers, this feels far more natural than being tied to long charging stops and constant worries about battery health. In my eyes, hydrogen is also more environmentally friendly than constantly producing and replacing giant battery packs that sooner or later end up as waste.

The sad part is that hydrogen still gets very little serious support compared to battery cars. It is treated as something experimental instead of as a real option. If we invested in hydrogen cars and infrastructure today with the same intensity that battery cars once received subsidies, I am convinced we would finally see a real shift away from fossil fuel. Once hydrogen cars are available in large numbers on the used market, and research brings their prices close to combustion cars, people will start buying them on their own simply because they fit their everyday life much better.

The Real Tragedy

We are using huge areas of good farmland to grow fuel crops just to slightly greenwash fossil gasoline, while policy chases a battery solution that does not work for most people. When we could use the same land to produce clean energy and hydrogen for engines that actually fit the way people already use and want to use their vehicles.
