An alternative to conventional methods of storing energy
Biochar has a porous structure with a high surface area, making it an excellent material for adsorbing and storing hydrogen gas. This offers a sustainable alternative to conventional storage methods.
Poplar wood chip biochar, in particular, is chemically stable, ensuring safe and efficient hydrogen storage. Under optimal conditions, it can hold up to 3 wt% of its own weight in hydrogen.
The scalability and cost-effectiveness of biochar compared to other storage materials make it economically attractive. Furthermore, biochar’s ability to regenerate after hydrogen release minimizes waste at the same time. According to a recent economic benefit analysis conducted in China, the internal rate of return for biochar used for hydrogen storage is approximately 22%.
