Flipping the pages from one chapter to another is easy to do in a book. In real-life, it can take much longer and often times it's painful, clunky, and expensive. This is why many industries and communities are struggling with a transition from fossil fuels to greener energy: our entire infrastructure for more than a century has been built on fossil fuels. Change can take time. 

The transportation industry was quick to introduce battery-powered vehicles but they're continuing to learn and evolve as they go. Power-levels, recharging capabilities, and cost are all areas that need to improve before seeing widespread adoption. In the trucking segment, however, they're taking a more “hybrid” approach. Not hybrid engines, but rather combustion engines that use greener fuel: hydrogen. 

It's not without trials and tribulations, but for the millions of trucks on the road around the world, revising the fueling method (to green hydrogen) could be much faster and less expensive than overhauling it completely to battery power. The emissions are still low, the engine power is still high, and the number of miles a truck could go each day would remain the same. 

This is the kind of middle-step that the world needs right now in order to get to a fully-electric future. We just need the R&D breakthroughs that will make manufacturing green hydrogen a realistic alternative.
