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.

Could green hydrogen be key to a carbon-free economy? The Saudis are going big on something called green hydrogen — a carbon-free fuel made from water by using renewably produced electricity to split hydrogen molecules from oxygen molecules. hydrogen is a lot more expensive than other fuels such as natural gas.

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.

At the same time, Brussels signaled that it will also encourage the development of "blue" hydrogen produced from fossil fuels paired with carbon capture, at least for the time being. The Global CCS Institute, a carbon capture think tank based in London, called the EU's strategy ambitious, but warned against picking winners.
