In this episode of Innovate and React, host I sit down with Jonas Massa, co-founder of AKROS Energy, to tackle the pressing challenges of hydrogen storage and transportation. While green hydrogen is a promising energy carrier for fluctuating renewables, its highly flammable nature poses significant safety and regulatory hurdles, especially for decentralized applications involving non-specialist personnel. Jonas breaks down why conventional storage methods, like highly pressurized vessels or toxic ammonia, fall short for widespread, small-scale use.
To solve this, AKROS Energy is developing a revolutionary method that stores hydrogen in everyday, non-toxic salts, namely potassium bicarbonate and potassium formate. Jonas explains their streamlined, low-temperature catalytic process and they want to scale it up. A great alternative to Ammonia and LOHC.
