What is CCUS (Carbon Capture, Utilization, Storage)? Carbon Capture, Utilization, and Storage (CCUS) is a set of processes used to “capture” carbon dioxide (CO2) from emissions generated by large-scale industrial and power generation processes. CCUS is a decarbonization solution that can be used in any process that uses a fossil fuels – including power generation, steelmaking, cement production, refining and petrochemical production, natural gas processing, and ammonia and fertilizer production. Once CO2 is captured, it can be transported for use in certain industrial processes or for safe and permanent sequestration underground. How is CO2 captured? There are three main categories...

Hydrogen is a versatile energy carrier. It is one of the most efficient fuels on Earth, with the highest energy content per weight. Hydrogen can be stored for extended periods of time, making it a valuable complement to other renewable sources in the electricity system. Hydrogen can be produced from almost all energy resources. A color code system identifies the different means: Grey Hydrogen – is produced by steam reforming of natural gas. Today, this is the most common process. Blue Hydrogen – comes from the same process, but the resulting CO2emissions are captured and stored (CCS). Green Hydrogen – is produced by...

What is a diaphragm compressor? Diaphragm compressors move (and compress) gas using a set of three, flexible diaphragm membranes. Gas enters the compressor’s process head from an external tank or process on its down-stroke. On the up-stroke, the diaphragms flex, reducing the area inside the chamber, pushing the gas out of the compressor (and on to the process/application). The oscillating movement of the diaphragms is driven by a reciprocating piston and crankshaft mechanism. Only the process diaphragm and the compressor’s process head come in contact with the gas. This is important because the diaphragms prevent hydraulic fluid (or oil from...

What are Hydrogen Fuel Cells? Hydrogen fuel cells produce electricity in a similar way that lithium-ion battery cells power electric cars – but Hydrogen fuel cells do not run down or need recharging. Like a battery, a Hydrogen fuel cell consists of two electrodes: a negative electrode (or anode) and a positive electrode (or cathode)—sandwiched around a polymer electrolyte membrane. Process for Hydrogen Fuel Cells Hydrogen (stored in tanks or reformers) is fed using Sundyne PPI compressors to the anode side of the fuel cell, while oxygen (from the air) is fed to the cathode side. On the anode side, a...
