As the global energy transition accelerates, the article explores the potential of repurposing existing oil and gas pipelines for hydrogen transportation. Despite financial barriers, the hydrocarbon industry is actively investigating modifications required for this shift. Challenges such as hydrogen embrittlement and energy density disparities drive the need for innovative solutions like using austenitic stainless steel and fiber-reinforced polymer for pipeline materials. Further, safety measures and maintenance protocols in handling hydrogen's flammability are vital considerations. The article delves into pipe-in-pipe systems as a promising solution to monitor and capture any leaked hydrogen within pipelines. While the economic viability of retrofitting pipelines versus constructing new ones varies, collaborations between different industries are highlighted as a strategy for advancing hydrogen development. The repurposing of workforces from traditional fossil fuels to hydrogen is also emphasized as a way to future-proof the industry. Overall, the article presents a positive outlook on the pioneering innovations in repurposing pipelines for a hydrogen-fueled future.
