The article discusses three innovative projects driving advancements in green hydrogen production and carbon capture initiatives. Firstly, FiBrane presents a groundbreaking technique for efficiently converting seawater into ultrapure water essential for offshore green hydrogen production. This method can significantly enhance the sustainability of hydrogen production processes, particularly for marine applications. Secondly, the Greensand Future project aims to implement a medium-scale carbon capture and storage solution, intending to store 300,000 tonnes of CO2 annually in a former oilfield. This initiative aligns with the European Union's ambitious net-zero goals and showcases the potential for repurposing existing infrastructure for environmental benefits. Lastly, the HYFLEX project focuses on improving energy efficiency by establishing a hydrogen storage facility with a 10-tonne capacity and expanding the electrolysis capacity of an existing methanol plant. By integrating hydrogen production with methanol manufacturing, this project demonstrates a synergistic approach to enhancing the overall sustainability and productivity of industrial processes. These projects collectively highlight the growing momentum towards innovative solutions in clean energy production and carbon mitigation efforts.
