Picture this: the looming shadow of climate change is finally receding. The planet's temperature is stabilising. Rainforests and coral reefs are beginning to thrive once more. This isn't just wishful thinking - it can be our reality if we embrace the power of hydrogen. Hydrogen is simple to harness, simple to use, and has the potential to bring clean energy to every corner of the globe. As leading energy expert Marco Alvera explains, if we're going to heal the climate, we need to start thinking big. So whether you're a policy-maker, a business person, an activist, or just simply curious, this book is a blueprint for how to get us there.
