BEST4Hy: paving the way for a sustainable management of end-of-life fuel cells

Horizon 2020 research and innovation project BEST4Hy – SustainaBlE SoluTions FOR recycling of end-of-life Hydrogen technologies – is developing low-environmental-impact technologies for the recovery and recycling of materials vital to the hydrogen supply chain, while considering the policy framework that could support sustainable management of end-of-life (EoL) fuel cells. This article introduces the BEST4Hy project and provides an analysis of the challenges and opportunities associated with the recycling of EoL hydrogen technologies.

Electrodeionization processes for ultrapure water production in green hydrogen generation

It is well documented that all electrolysers require ultrapure water (UPW) as a feedstock for hydrogen production. Nine litres of water are required to produce 1 kg of hydrogen, and approximately 200 litres per hour of UPW are required per MW of electrolyser capacity. The importance of UPW is to ensure the efficiency and longevity of the electrolyser through the prevention of fouling or scaling. Electrodeionization (EDI) is an electrochemical membrane process that may be used as part of the UPW preparation. This article aims to explain the EDI process and highlight its advantages, especially for high capacities that will be needed as hydrogen generation scales up.

Green ammonia production: harnessing green hydrogen

Ammonia, a cornerstone of the global food supply chain, has traditionally been produced through carbon-intensive methods. This article discusses the need for and potential of green ammonia, which is produced by integrating green hydrogen with the Haber-Bosch process. It highlights the challenges such integration presents, innovative solutions to overcome them, and the positive impact of doing so.

The role of solid oxide electrolyzers in the green hydrogen landscape

In a world grappling with the urgent need to reduce carbon emissions, the future of hydrogen is undeniably bright. As the demand for low-carbon hydrogen continues to grow, we find ourselves on the cusp of a transformative energy shift. According to the two-degree Paris Agreement scenario, the demand for low-carbon hydrogen is projected to reach a staggering 343 million metric tonnes per annum (Mtpa). Of this potential demand, green hydrogen is expected to account for 70%, or roughly 241 Mtpa. Now, compare that to today’s reality, where a mere 80 Mtpa is being produced as grey hydrogen worldwide. This means that the green hydrogen market alone is poised to become three times the size of the current grey hydrogen market.
