As an expert in the field of energy and sustainability, I have a deep understanding of the costs and benefits associated with various energy sources, including hydrogen fuel and petrol. The question of whether hydrogen fuel is cheaper than petrol is a complex one, involving a multitude of factors such as production costs, distribution, and current market prices.

To begin with, the cost of hydrogen fuel is primarily determined by its production method. There are three main ways to produce hydrogen: steam methane reforming, electrolysis using electricity, and biomass gasification. Each method has its own cost implications. Steam methane reforming, which is currently the most common method, involves extracting hydrogen from natural gas, a process that is relatively inexpensive but contributes to greenhouse gas emissions. Electrolysis, on the other hand, can be powered by renewable energy sources, making it a cleaner option, but it is currently more expensive than steam methane reforming. Biomass gasification is another method that can be cost-effective and environmentally friendly, but it is still under development and not widely used.

The cost of petrol, on the other hand, is influenced by factors such as crude oil prices, refining costs, taxes, and distribution costs. Petrol prices can fluctuate significantly due to geopolitical events, changes in supply and demand, and other market forces.

Comparing the two, it's important to consider the entire lifecycle cost, including production, distribution, and end-use. While the production cost of hydrogen fuel is currently higher than that of petrol, especially when produced through electrolysis, the potential for cost reduction through technological advancements and economies of scale is significant. For instance, the reduction in the cost of solar panels, as mentioned in the provided reference, could make renewable hydrogen more competitive.

Moreover, the infrastructure for hydrogen fuel is still in its early stages compared to the well-established petrol infrastructure. This means that the distribution and refueling costs for hydrogen are currently higher. However, as the infrastructure develops and more vehicles are converted to use hydrogen fuel, these costs are expected to decrease.

It's also worth noting that the environmental impact of hydrogen fuel is generally lower than that of petrol. Hydrogen fuel cells produce water as their only emission, whereas petrol combustion releases carbon dioxide and other pollutants. This environmental benefit could become a significant factor in the cost equation as regulations tighten and the demand for cleaner energy sources grows.

In conclusion, while hydrogen fuel is not currently cheaper than petrol when considering all aspects of the cost, it has the potential to become more cost-effective in the future. The transition to renewable energy sources for hydrogen production, advancements in technology, and the development of infrastructure will play crucial roles in determining the future cost competitiveness of hydrogen fuel.
