  • Valves, Actuators & Regulators Blog: Crucial Role for Valves, Regulators & Actuators in Blue Hydrogen Production Podcast

    Jim Cahill
    You may have heard of various color adjectives used to describe hydrogen production based on the amount of CO2 produced as a byproduct. Green hydrogen comes from renewable energy sources, powering an electrolyzer to split water into hydrogen and oxygen. Blue hydrogen is produced from typical sources like natural gas, but the CO2 produced as a byproduct is captured and stored away. This decarbonization process is one…

  • Valves, Actuators & Regulators Blog: Control Valve Selection in Plastic Pyrolysis Applications

    Jim Cahill
    Since their introduction over a century ago, plastic products have become ubiquitous. Unfortunately, plastic waste degrades very slowly, and over time it breaks down into microplastics that harm the environment. Some efforts to address this problem involve replacing plastics with biodegradable alternatives, while others seek to recycle plastics after use. However, recycling plastic is difficult compared to materials…
