acatech HORIZONS: Hydrogen

You may still vaguely remember hydrogen from your first chemistry lessons. If you burn it, energy is released. Its advantage is that this releases only water, not environmentally harmful gases. If pro-duced in a climate-friendly way, it can help us turn our backs on fossil fuels such as coal and natural gas once and for all and finally make industry, transport and energy supply sustainable. But how does this work and what technologies are already available? Where will the hydrogen come from? What is conceivable in the future and what still needs to happen? If this has piqued your curiosity and you’ve been on the lookout for a fact-based yet easy-to-understand overview of hydrogen for a while then you’re in the right place!
