Carbon Capture and Storage through Methane Hydrate Displacement

Energy Research and Development

Research

A system designed to help engineers sculpt and refine engine designs to improve their efficiency and power.

Crystalline solids composed of gas molecules trapped within a lattice of water molecules. According to the research, they can hold various forms of fuel including natural gas and hydrogen, and are readily available in the planet's oceans.

Process of capturing carbon dioxide emissions and storing them to prevent release into the atmosphere. The research proposes using methane hydrates as a storage medium.

United States

Research project conducted by PNNL to develop and validate a computer model demonstrating CO2 capture through methane hydrate displacement. The study quantifies molecular-level interactions between gases and water to show that methane can be efficiently replaced with CO2 in gas hydrate structures.
