Wash. Company Captures Carbon from Natural Gas for Building Roads

Contractors test workability

A Washington company says it has developed a way to capture carbon from natural gas and use it to make asphalt to build roads. Modern Hydrogen uses a process called methane pyrolysis that produces clean hydrogen out of methane and captures the carbon from that gas before it reaches the atmosphere. Methane, which is four parts hydrogen […]

Tribes and dairy farmers made a model renewable energy program. It’s about to get even better

About 85,000 gallons a day of cow manure and food waste flow into the pit at Werkhoeven Dairy in Monroe, Washington. The digester captures methane that powers a generator, producing enough renewable energy for nearly 700 homes. This is an example of one of the uses of hydrogen that can come from RNG.

Tour participants got a close look at a sample of the carbon that will soon be captured at the dairy digester. A Bothell, Wash.-based company called Modern Hydrogen will extract granulated carbon from methane to produce pure hydrogen.
“So this technology lets them take that methane that’s getting delivered to them and convert it to hydrogen so that they can burn the hydrogen and then collect the carbon instead of spewing it in the air,” Robinson said.
The only emissions from burning hydrogen is water vapor. It’s about the cleanest fuel out there. And methane is just about the dirtiest, before it’s burned. It’s more than 25 times more potent than carbon dioxide at trapping heat in the atmosphere, according to the Environmental Protection Agency.
The technology comes from Modern Hydrogen, previously known as Modern Electron. The Bothell, Wash.-based company is focused on reducing emissions from biogas, like what Qualco Energy produces from cow manure, within the existing gas infrastructure.
