Power to Gas Energy Storage

The ‘power’ is electricity that’s not yet used to light up homes, the ‘gas’ is hydrogen and the

process is simple electrolysis: separating the H2 and O components of water.

It’s widely understood to refer to power generated by renewables like wind and solar, and so

electrolysers have been designed especially to handle the intermittency.

The resulting hydrogen is easy to store — it can be turned back into electricity, converted to

natural gas-like methane, or used as fuel for hybrid cars.

As the proportion of renewable energy supply to the electricity grid increases, the ability to

match this unscheduled intermittent supply with demand becomes increasingly problematic. In

fact as the deployment meets and exceeds 20% capacity, as already experienced in many

countries, grid balancing issues become acute leading to the curtailment of wind. This is driving

the need for long term, large scale energy storage solutions.

Power-to-Gas is the process of converting surplus renewable energy into hydrogen gas by rapid

response electrolysis and its subsequent injection into the gas distribution network.

Most developed countries already own a vast energy storage infrastructure through the

pressurisation of existing transmission and distribution infrastructure. This allows it to be

recharged without the need of it being discharged first, so when the wind blows, this can be

taken and used to top up storage, this is critical for storing renewable energy which is

intermittent in its generation.

Power-to-Gas allows for the storage of significant amounts of energy and the provision of CO2

neutral fuels in the form of the resulting renewable energy gas mix of hydrogen and methane.

The hydrogen produced is injected into the natural gas system to displace natural gas, so

reducing greenhouse gas emissions and reliance upon fuel imports. If the power is derived

mainly from renewable power sources, only low-carbon hydrogen will be produced. Thereby the

Power-to-Gas (P2G) approach can facilitate a transition from natural gas to a ‘green’ mixed gas

by making use of both of the existing energy grids on a global scale.

Power-to-Gas is a highly effective way of integrating renewables. It can provide a rapid,

dynamic response to the Independent Grid Operator’s signal to adjust to the variations in

renewable generation output. The siting of a Power-to-Gas facility is not restricted to any

geologic formation as it can be deployed wherever the power and gas grids intersect. It is a

scalable technology.

Power-to-Gas provides the unparalleled energy storage capacity in the TWh range—seasonal

storage capability. It can charge energy several days, or even consecutive weeks, without

needing to discharge the stored energy.
