Natural gas storage

Squeeze it, chill it, or let a porous solid hold it at a fraction of the pressure.

Adsorbed Natural Gas (ANG): How It Works, Storage Capacity and Limits: Adsorbed natural gas storage puts a porous solid inside the tank, which then holds four to five times more methane at 35 bar than the empty vessel would. The heat, the leftover gas and the packing density are where the engineering gets hard.
Natural Gas Storage Tanks: CNG Tank Types, Capacity, Standards, Safety: An 80-liter steel cylinder at 200 bar holds about 13 kg of methane and weighs over 100 kg empty. Every later design of CNG storage tanks, from carbon fiber wraps to vacuum jackets, tries to change that ratio.
CNG vs LNG: How Compression and Liquefaction Compare for Vehicles: Both fuels are the same methane. One is squeezed to 250 bar, the other cooled to −162 °C, and that single choice decides tank size, station cost and which trucks each one suits.
Renewable Natural Gas (RNG): Where It Comes From and How It Is Used: Raw biogas from a landfill is barely half methane. Cleaned up to pipeline quality, it becomes a fuel that fills the same CNG cylinders and LNG tanks as fossil gas, with a very different carbon score.
Is Natural Gas Clean? Methane, Emissions and the Cleanest Fossil Fuel: Burned, natural gas releases about 43% less carbon dioxide than coal for the same energy, the basis of its name as the cleanest fossil fuel. Leaked, its methane traps heat about 30 times more strongly than CO2 over a century. Both facts belong in the answer.

Cylinders, regulators, fast-fill stations and the vehicles that convert cheapest.

What Is CNG? Compressed Natural Gas Vehicles and Their Fuel Explained: Natural gas pressed into steel or composite cylinders at 200–250 bar powers more than twenty million compressed natural gas vehicles worldwide, from Delhi buses to Italian hatchbacks. Here is what the fuel is and how it behaves.
CNG Fueling Stations: How Fast-Fill and Time-Fill Systems Are Built: A CNG station is a compressor plant with a dispenser attached. Its layout depends on one question: do vehicles arrive at random during the day, or park at the same depot every night?
Converting a Vehicle to Natural Gas: Kit Parts, EPA Rules and Payback: A gasoline engine needs surprisingly little hardware to burn methane. The difficult parts are the cylinder package, the emissions paperwork and the arithmetic that decides whether the conversion ever pays for itself.
Natural Gas Motorcycles, Scooters and Auto-Rickshaws: How They Run: Small two-stroke engines were among the dirtiest vehicles on Asian streets. Natural gas cleaned up Delhi's auto-rickshaws within a few years, but fitting a cylinder to a motorcycle proved much harder.

Where no pipe reaches, gas travels by road to factories, mines and remote towns.

Virtual Pipeline Explained: CNG and LNG Travel as a Pipeline on Wheels: Where a gas main would take years to build or never pay back, the gas can come by truck instead. A virtual pipeline, or pipeline on wheels, replaces steel in the ground with trailers on a schedule.
Stranded and Flared Gas: Small-Scale Ways to Capture and Use It: Satellites counted 167 billion cubic meters of gas burned in oil-field flares in 2025. Most of it sits at sites too small or remote for a pipeline, which is where trucks, small plants and generators come in.
LNG Trucking: Cryogenic Fuel Tanks, HPDI and Spark Engines, Hold Time: A heavy truck that needs 1,000 km between fills cannot carry enough compressed gas. Liquefied at −162 °C, the same methane takes less than half the tank volume CNG needs, at the price of a fuel that is always slowly boiling.

The same storage problem with a smaller molecule: 700-bar tanks, liquid hydrogen, hydrides.

Hydrogen Storage Guide: Methods, Tanks, Densities and Their Limits: A kilogram of hydrogen carries almost three times the energy of a kilogram of gasoline, yet at room conditions it fills about eleven cubic meters. Each of the hydrogen storage methods is a different answer to that mismatch.
Hydrogen vs Natural Gas: Energy Density, Flames, Leaks and Storage: Hydrogen and methane share pipes, burners and even some tanks in the plans of gas utilities, yet they behave like different fuels the moment they leave the valve.
Metal Hydrides and MOFs: How Solids Hold Hydrogen, and What It Costs: A canister of metal powder can hold more hydrogen per liter than a 700 bar tank, at a pressure of a few bar. It also weighs many times more, and it gets hot when you fill it.
Hydrogen Blending in Natural Gas Grids: Limits, Energy Content, Trials: Twenty percent hydrogen by volume sounds like a fifth of the way to a hydrogen grid. In energy terms it replaces about seven percent of the natural gas, and that gap shapes every argument about blending.
