World-first home hydrogen battery stores 3x the energy of a Powerwall 2

Australian company Lavo has debuted a hydrogen production, storage and conversion system for the home. It stores up to two days' worth of energy from your rooftop solar – and should outlast a lithium battery by many years. So what's the catch?

World first: Dutch brewery burns iron as a clean, recyclable fuel

Yes, iron. Fine iron powder can burn at high temperatures, emitting nothing but rust as a by-product. That rust can be reduced back into iron powder using renewable energy to create a clean, renewable combustion fuel that could have big implications.
