Methane to hydrogen energy storage

How to save methane consumption compared to conventional hydrogen production?

Compared with conventional hydrogen production via industrial SMR approach, saving in methane consumption by the new approach corresponds to the amount of combusted methane as substituted by solar thermal energy via CSE, and by solar PV electricity for the separation of H 2 and CO 2 products .

Does mixing hydrogen and methane increase energy storage capacity?

Here, we show, from first-principles theoretical calculations, that mixing hydrogen and methane gas may significantly increase the energy storage capacity compared with either pure hydrogen or methane.

Can natural gas convert methane into hydrogen?

Researchers from Pacific Northwest National Laboratory (PNNL) and West Virginia University (WVU), in collaboration with industry partners Southern California Gas Company (SoCalGas) and C4-MCP, have developed a process that converts methane—the primary component of natural gas—into hydrogen while emitting zero CO2.

How can hydrogen be stored?

Physical storage of hydrogen via compression or liquefaction is the currently the most mature technology but requires significant energy.

How much methane is saved per kg of hydrogen produced?

Additionally, the methane saving and CO 2 emission reduction per kg of hydrogen produced are up to 1.29 and 3.55 kg (at 0.16 V), respectively.

Is methane pyrolysis a viable option for sustainable hydrogen production?

As the costs of renewable energy continue to decline, the feasibility of such integrations will likely increase, making methane pyrolysis an even more attractive option for sustainable hydrogen production. Moreover, the development of markets for carbon byproducts will play a pivotal role in driving economic viability of methane pyrolysis.
