Public transportation across the country has been using CNG for decades, with about 12-15% of public transit buses in the U.S. currently running on natural gas (either CNG or LNG – liquefied natural gas). That number is growing, with nearly one in five buses on order today slated to run on natural gas. States with the highest consumption of natural gas for transportation are California, New York, Texas, Georgia, Massachusetts and Washington, D.C.
Gas escaping from pipework needs to be detected quickly. Depending on the type of gas, the consequences range from merely wasteful to fatal. Leaking gas can be environmentally damaging, it can create an explosion risk, and it can even kill thousands of people, as happened in the Bhopal chemical plant disaster.
We know many distributors, engineers and customers have the knowledge needed to select the right valve for their application. But, if you’ve got questions and want to save time, we recommend you download and read our new white paper, “A Guide to Selecting an Excess Flow Valve,” to make sure you’ve completed the checklist.
Our flow monitors, meters and valves find their way into a very diverse range of applications. Equipment designers choose them primarily for their performance, but minimizing the total cost of ownership is usually a concern too.
Those in California have been doing a great job of reducing their water usage, but there’s still a major shortage. Worldwide, water is becoming a precious commodity, which may seem strange when two thirds of the globe is covered in it.
ChemTec is an engineering-driven company, and engineering is really about applying the Laws of Physics. We’re familiar with analyzing gas flow rates, accounting for expansion coefficients, and monitoring the position of suspended magnetic pistons, but optical engineering is outside of our realm. Or it was until a customer set us a challenge we couldn’t resist.
With supply exceeding demand, producing the silicon panels for photovoltaic (PV) power generation has been an intensely competitive business for several years. There are however reports that a turnaround is underway. Solar industry observers like Greentech Media (GTM) state that with capacity growing only slowly, manufacturers are beginning to see signs of better margins ahead.
For most of us, the air we breathe is cleaner now than it was a decade ago. That’s good news, but it does depend on where you live. The American Lung Association’s (ALA) 2015 “State of the Air” report says, “Nearly 138.5 million people—almost 44 percent of the nation—live where pollution levels are too often dangerous to breathe.” The situation is especially bad in the western USA, with many urban areas in California suffering high levels of air pollution.
Gas producer, Air Products (AP), recently unveiled a solar-powered hydrogen fueling station. Their SmartFuel® technology uses electrolysis to make hydrogen from water, so providing fuel cell vehicles with power that’s truly ‘green.’
Fuel cells, which produce electricity by combining hydrogen and oxygen, offer a tantalizing glimpse of an oil-free future. An alternative to carrying heavy batteries, a fuel cell-powered car needs only a supply of hydrogen to generate all the energy it needs.
