A session on the lookout at the worth of mixing hydrogen into the current United kingdom fuel grid as a usually means to lessen all round emissions from the network has been introduced by the govt.

Comments is being sought right up until 27 October on the issue of irrespective of whether a selection to start out blending hydrogen into the UK’s gasoline distribution networks would have enough economic price and environmental rewards to assistance decarbonise vitality and heat.

The doc mentioned: “[The] Federal government is aiming to get to a strategic plan final decision in 2023 on no matter if the govt must guidance mixing of up to 20 for each cent hydrogen by volume into the GB gasoline distribution networks. We are examining whether or not there may be worth in acquiring hydrogen mixing readily available to support the early phases of the hydrogen economic system.”

Investigate into hydrogen blending has seemed at how existing all-natural gasoline boilers can use a gas mix with a volume of up to 20 for every cent hydrogen with out getting to make amendments to a heating method.

Whilst hydrogen has no carbon emissions at the point of use, concerns have been raised all over the environmental impacts and expense of producing the gasoline at sufficient scale to decarbonise heating when compared to striving to grow the use of small carbon systems these as warmth pumps.

New study from United kingdom-primarily based innovation charity Nesta has argued that hydrogen was ‘too costly and inefficient’ for widescale use in domestic heating with the majority of provides of the gas as well dependent on fossil fuels for era.

Producing the situation for blending

A person of the possible criteria of the government’s most recent hydrogen mixing session is to contemplate what purpose mixing might perform in addressing heating together with, together with other employs this kind of as transport, energy generation and industrial processes that would be ‘harder to electrify’.

The consultation observed that a selection to blend hydrogen at a volume of up to 20 for every cent in the present GB fuel distribution networks could see a carbon price savings of involving 6 to 7 for every cent from existing fuel need.

Having said that, It included that the risk of cutting some of the emissions from current normal gasoline boilers was not the “primary strategic role” of blending into the current gas grid.  The doc additional that the government’s plan to acquire a final decision by 2026 if it would back again some part for the use of 100 per cent hydrogen in heating houses – together with sector ready technologies this kind of as warmth pumps and reduced carbon heat networks – was also unrelated to the outcomes of the selection to blend hydrogen gas.

The doc mentioned: “Alongside our work on blending, the authorities is performing with sector and regulators on a selection of investigation, improvement and tests jobs, including community trials, to empower strategic choices in 2026 on the job of 100 per cent hydrogen for heat.”

“In mild of these decisions, and as the hydrogen financial state develops outside of our first blending coverage decision, we will proceed to evaluate the strategic role and benefit of blending.”

Some of the major concerns talked over in the new consultation ended up concerns that encouraging blending in the gas grid, even as a suggests to control some of the emissions from the present fuel grid, could serve to sluggish down a motivation to scale up use of minimal carbon heating programs.

The document reported: “We are distinct that mixing is not a substitute for actions that supply whole decarbonisation of heating this kind of as accelerating deployment of heat pumps and small carbon heat networks and taking into consideration the possible position of 100 per cent hydrogen for heat in the for a longer period-time period. It will be important that there is constant messaging that the aim of blending would be to guidance broader hydrogen overall economy development, fairly than to decarbonise heat.”

A strategic conclusion is supposed to be taken above the course of 2023 about whether to transfer ahead with mixing of hydrogen into the current gas networks.  Need to a choice be backed by the govt to start off hydrogen blending up to 20 for every cent, then further more operate would the be carried out to established out what professional aid will be necessary to oversee this perform.

Any decision would be primarily based on components which includes undertaking a mixing safety overview, as perfectly as things to consider from the most up-to-date session about economic and strategic benefit of this kind of a conclusion.

The consultation stated: “We would then search to start the legislative and regulatory process to carry out this, as properly as the course of action to make any physical improvements to GB distribution networks that may possibly be required. Supplied the timelines for this operate, we do not anticipate mixing at a industrial scale to commence in GB prior to 2025-26, at the earliest.”
