Safe Hydrogen Storage with Salts: Alternative to Pressure Tanks and Ammonia

/

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.

Turning Methane into Value-Chemicals via Photocatalysis

/

In this episode we discuss a novel and sustainable approach to converting methane into valuable chemicals. Currently light hydrocarbons like methane are often simply burned for energy, despite their potential as a carbon source for the chemical industry. Traditional conversion methods like natural gas cracking are energy-intensive, and other functionalization routes require harsh conditions and often toxic chemicals. Dr. Andrés Constantino sharess his research focusing on photocatalysis to achieve the direct functionalization of methane under milder conditions.
The key to this method is a supramolecular catalytic system using FeCl3•6H2O and collidine. When irradiated, the catalyst generates a highly active chlorine radical that efficiently abstracts hydrogen from the inert alkane (methane) to form an alkyl radical. The collidine plays a crucial dual role, acting as a base to quench the resulting HCl and as a ligand that stabilizes the iron tetrachloride core. The radicals were used for allylation chemistry, which retains a useful olefin group in the product.

How ion-exchange resins can make a reaction more sustainable

/

This episode provided a deep dive into how ion exchange resins could revolutionize aldol reactions, making them greener and more sustainable. While traditional catalysts like sodium hydroxide are cheap, their environmental and economic drawbacks make alternative solutions necessary. Ion exchange resins, particularly those with improved linker stability, show promise, though challenges like clogging must be addressed before industrial adoption.

The discussion underscored the broader importance of catalysis in chemical research and industry, particularly in reducing waste, energy consumption, and process costs. As research progresses, these insights could lead to more efficient and sustainable chemical production methods, aligning with the goals of green chemistry. En example is the aldol reaction, an essential process in the chemical industry for producing pseudo-ionone, a precursor for vitamin A. This reaction was used as the model reaction, to investigate the ion-exchange resins as possible heterogeneous catalysts.
