Increasingly, hydrogen is gaining traction as both a <a href=\"https:\/\/blog.wika.com\/us\/\/knowhow\/momentum-gathers-for-hydrogen-vehicles\/\" target=\"_blank\" rel=\"noopener\">transportation fuel<\/a> and a feedstock for the creation of <a href=\"https:\/\/blog.wika.com\/us\/\/applications\/wika-expertise-in-fertilizer-process-instrumentation\/\" target=\"_blank\" rel=\"noopener\">fertilizers<\/a> and important products, especially when H<sub>2<\/sub> is produced with renewable energy (green hydrogen).<\/p>\n<h2><strong>Types of Hydrogen Compressors<\/strong><\/h2>\n<p style=\"font-weight: 400\">There are several types of gas compressors. Each design has benefits and drawbacks, and the choice of which one to use depends on the particular gas, the available installation space, the desired compression ratio and throughput, etc.<\/p>\n<p style=\"font-weight: 400\">The types of units most commonly used to compress hydrogen include:<\/p>\n<ul>\n<li><strong>Piston compressor <\/strong>\u2013 This is a type of reciprocating\/linear compressor that uses a back-and-forth motion to push the hydraulic rod and piston in order to reduce the volume that the gas occupies. Advantages of a <a href=\"https:\/\/www.wika.com\/en-us\/piston_compressors.WIKA?highlightedText=motor\" target=\"_blank\" rel=\"noopener external\">piston compressor<\/a> include a relatively compact footprint and high compression ratio.<\/li>\n<li><strong>Diaphragm compressor <\/strong>\u2013 This is another type of reciprocating\/linear compressor. But rather than having the piston itself displace the gas, the rod pushes against a flexible disk. This membrane effectively separates the mechanism\u2019s hydraulic oil from the compressed gas. For extra safety and purity, a diaphragm-type hydrogen compressor typically uses metal diaphragms in three places: oil side, intermediate, and gas side.<\/li>\n<li><strong style=\"font-size: 1rem\">Ionic compressor<\/strong><span style=\"font-size: 1rem\"> \u2013 This type of reciprocating\/linear compressor uses a column of ionic fluid rather than a mechanical system to move the piston. Since there are no crankshafts, hydraulic rods, bearings, or seals, ionic compressors experience fewer failures than most other types of hydrogen compressors. The ionic fluid also protects metal parts from <\/span><a style=\"font-size: 1rem\" href=\"https:\/\/blog.wika.com\/us\/\/applications\/measurement-technologies-for-a-hydrogen-economy\/\" target=\"_blank\" rel=\"noopener\">hydrogen permeation and embrittlement<\/a><span style=\"font-size: 1rem\">.<\/span><\/li>\n<li><span style=\"font-size: 1rem\"><strong style=\"font-size: 1rem\">Centrifugal compressor<\/strong><span style=\"font-size: 1rem\"> \u2013 This turbine-based compressor reduces a gas\u2018s volume using an impeller rotating at very fast speeds. Also called a turbo compressor, the advantage is a high throughput using a single stage, provided that the rotational speed is fast enough and the impeller is large enough. One possible downside is its large footprint.<\/span><br \/>\n<\/span><\/li>\n<\/ul>\n<p style=\"font-weight: 400\">Compressors are driven by either a <a href=\"https:\/\/www.wika.com\/en-us\/hydraulic_power_packs.WIKA?highlightedText=hydraulic\" target=\"_blank\" rel=\"noopener external\">hydraulic power unit<\/a> or an electric motor, and it can take two or more stages to sufficiently reduce the volume of hydrogen gas for storage and transport. The initial inlet pressure is 20 to 200 bar, and the eventual outlet pressure is 700 bar or more.<\/p>\n<h2><strong>Hydrogen Compression: A Hot Topic<\/strong><\/h2>\n<p style=\"font-weight: 400\">As the least dense molecule, a tremendous amount of energy is needed to compress hydrogen to the high pressures required. This process greatly increases the gas\u2019s temperature, and significant heat is generated. That\u2019s why mechanical hydrogen compression systems are equipped with <a href=\"https:\/\/www.wika.com\/en-us\/refrigeration_technology.WIKA\" target=\"_blank\" rel=\"noopener external\">refrigeration systems<\/a>, with highly pressurized hydrogen passing through a heat exchanger to cool it to about \u221240\u00b0F (\u221240\u00b0C), making the gas safer to work with and store.<\/p>\n<p style=\"font-weight: 400\">For the hydrogen compression systems with crankshafts, connecting rods, and other mechanical parts, the compressor bearing also heats up, and its temperature needs to be monitored. If a <a href=\"https:\/\/blog.wika.com\/us\/\/applications\/wikas-electronic-switches-offer-high-customization-hydraulic-power-units\/\" target=\"_blank\" rel=\"noopener\">hydraulic power unit<\/a> drives the mechanics, industrial sensors are needed to monitor and control the unit\u2019s pressure, temperature, and fluid levels.<\/p>\n<h2><strong>Measuring Instruments for Hydrogen Compressors<\/strong><\/h2>\n<p style=\"font-weight: 400\">An array of process-grade pressure gauges, pressure transmitters, and temperature sensors keeps hydrogen compressors operating safely and efficiently.
