Selective adsorption

Envirotec Magazine

The crystal structure of the K-GIS zeolite adsorbent: The size of cavities in the crystal is slightly larger than the CO2 molecule, permitting CO2 to enter the crystal and be adsorbed while larger molecules such as methane are excluded. Biogas from sewage sludge, garbage, and similar sources consists of approximately 60% methane and 40% CO2.

CH4nge is in the air? Comparing laser and FID for landfill emissions monitoring

Envirotec Magazine

The accurate and effective monitoring of surface methane emissions levels is critical to the safe operation of landfill and waste management sites. However, methane monitoring equipment can sometimes be more of a hinderance than a help. Another way? It is able to detect emissions from 1-10,000ppm or from 0.1%

Hydrogen-Powered Data Centers Poised to Transform AI Infrastructure

Hydrogen Fuel News

These facilities promise faster deployment times and a significantly lower carbon footprint compared to conventional setups connected to strained energy grids. The hydrogen is delivered in tanks and, currently, most of it originates from natural gas using processes like steam methane reforming.

Could trash-to-energy technology feed hydrogen demand?

GreenBiz

Early pioneers of these hydrogen-from-waste technologies such as Ways2H, SGH2 Energy (SGH2) and Standard Hydrogen say not only are they making carbon-free, energy-rich fuel, their approaches also will divert mountains of trash from landfills and waterways, cutting greenhouse gas emissions. . There are other ways to make hydrogen.

Heard of “Net-Zero Oil” or “Carbon Negative” Bioenergy? In 2023 You Will

DeSmogBlog

Salmon might seem like a good alternative to meat, in a world that needs to shift away from carbon-intensive cattle — at least the fish farming industry would have you see it that way. Carbon Capture and Storage. Below, a handful of DeSmog writers dive into the issues they’ll be watching in 2023. Aquaculture. Next year you will.
