The global push towards sustainable energy solutions has gained significant momentum . As countries worldwide strive to meet ambitious carbon reduction targets , the valve industry finds itself adapting to new challenges and opportunities presented by emerging technologies . This article explores the latest developments in hydrogen and renewable energy sectors , with a particular focus on the crucial role of valves in these evolving industries . Hydrogen , often hailed as the fuel of the future , is rapidly transitioning from concept to reality . With its potential to decarbonise various sectors , from transportation to heavy industry , hydrogen is becoming a cornerstone of many countries ’ energy strategies .
Hydrogen production and storage
The production of green hydrogen , using renewable energy sources to power electrolysis , is gaining traction globally . This process involves splitting water molecules into hydrogen and oxygen using electricity from renewable sources . It requires specialised valves capable of handling the unique properties of hydrogen , including its low molecular weight and high diffusivity . The electrolysis process presents several challenges for valve technology . Valves must withstand high pressures and temperatures while maintaining perfect sealing to prevent hydrogen leakage . They must also be resistant to hydrogen embrittlement , a phenomenon where hydrogen atoms diffuse into the metal structure , causing it to become brittle and potentially fail . Emerson , a major player in automation solutions , recently secured a significant order in the green hydrogen sector from Cavendish Renewable Technology ( CRT ), an Australian startup . The order includes software , control systems , instrumentation , valves and safety solutions for CRT ’ s hydrogen electrolysers and ammonia processing equipment . This project demonstrates how valve technology integrates with other systems in modern hydrogen production facilities , addressing the entire process from electrolysis to storage and distribution .
