In-depth Q&A: How will the UK’s hydrogen strategy help achieve net-zero?

In this post, Carbon Brief highlights bottom lines from the 121-page strategy and analyzes a few of the main talking points around the UKs hydrogen strategies.

On the other hand, company decisions around the extent of hydrogen usage in domestic heating and how to guarantee it is produced in a low-carbon method have actually been delayed or put out to consultation for the time being.

The UKs new, long-awaited hydrogen method supplies more information on how the government will support the development of a domestic low-carbon hydrogen sector, which today is essentially non-existent.

Specialists have alerted that, with hydrogen in brief supply in the coming years, the UK should prioritise it in “hard-to-electrify” sectors such as heavy market as capability expands.

Hydrogen will be “critical” for accomplishing the UKs net-zero target and could satisfy up to a 3rd of the nations energy needs by 2050, according to the government.

Why does the UK need a hydrogen technique?

The main range is based on illustrative net-zero consistent situations in the sixth carbon budget impact assessment and the complete range is based upon the entire variety from hydrogen technique analytical annex. Source: UK hydrogen strategy.

The strategy does not increase this target, although it keeps in mind that the government is “familiar with a possible pipeline of over 15GW of projects”.

Prior to the brand-new method, the prime ministers 10-point strategy in November 2020 included strategies to produce 5 gigawatts (GW) of yearly low-carbon hydrogen production capability in the UK by 2030. Presently, this capacity stands at virtually absolutely no.

As the chart below programs, if the federal governments strategies come to fulfillment it might then expand considerably– making up in between 20-35% of the nations overall energy supply by 2050. This will need a major expansion of infrastructure and skills in the UK.

There were likewise over 100 recommendations to hydrogen throughout the federal governments energy white paper, showing its potential usage in numerous sectors. It likewise includes in the industrial and transportation decarbonisation methods released previously this year.

The level of hydrogen use in 2050 imagined by the strategy is somewhat greater than set out by the CCC in its latest recommendations, however covers a comparable variety to other studies.

Hydrogen is extensively seen as a vital part in plans to accomplish net-zero emissions and has been the subject of considerable buzz, with numerous countries prioritising it in their post-Covid green healing plans.

The Climate Change Committee (CCC) has actually kept in mind that, in order to strike the UKs carbon budgets and achieve net-zero emissions, choices in locations such as decarbonising heating and vehicles require to be made in the 2020s to enable time for facilities and automobile stock changes.

In its new technique, the UK government makes it clear that it sees low-carbon hydrogen as a crucial part of its net-zero plan, and says it wants the country to be a “international leader on hydrogen” by 2030.

Business such as Equinor are pressing on with hydrogen developments in the UK, however industry figures have cautioned that the UK threats being left behind. Other European countries have pledged billions to support low-carbon hydrogen growth.

Critics also characterise hydrogen– many of which is presently made from gas– as a method for nonrenewable fuel source business to preserve the status quo. (For all the benefits and downsides of hydrogen, see Carbon Briefs thorough explainer.).

Today we have released the UKs very first Hydrogen Strategy! This is our plan to: kick-start a whole market release the market to cut expenses ramp up domestic production unlock ₤ 4bn of private capital assistance 9k jobs #BuildBackGreenerhttps:// t.co/ aHZTr5yYeR– Kwasi Kwarteng (@KwasiKwarteng) August 17, 2021.

The strategy also required a ₤ 240m net-zero hydrogen fund, the production of a hydrogen area heated with the gas by 2023, and increasing hydrogen mixing into gas networks to 20% to lower dependence on natural gas.

A current All Party Parliamentary Group report on the role of hydrogen in powering market consisted of a list of demands, mentioning that the government must “expand beyond its existing dedications of 5GW production in the upcoming hydrogen strategy”. This call has been echoed by some market groups.

Hydrogen development for the next years is anticipated to start gradually, with a government aspiration to “see 1GW production capability by 2025” laid out in the technique.

The document consists of an exploration of how the UK will expand production and produce a market for hydrogen based upon domestic supply chains. This contrasts with Germany, which has actually been aiming to import hydrogen from abroad.

In some applications, hydrogen will take on electrification and carbon capture and storage (CCS) as the very best means of decarbonisation.

Its versatility indicates it can be utilized to take on emissions in “hard-to-abate” sectors, such as heavy industry, however it currently suffers from high costs and low effectiveness..

Nevertheless, just like the majority of the federal governments net-zero strategy documents so far, the hydrogen strategy has been postponed by months, leading to unpredictability around the future of this new market.

What variety of low-carbon hydrogen will be prioritised?

The CCC has cautioned that policies must establish both blue and green alternatives, “instead of just whichever is least-cost”.

Green hydrogen is used electrolysers powered by renewable electrical power, while blue hydrogen is used natural gas, with the resulting emissions captured and saved..

Jess Ralston, an analyst at thinktank the Energy and Climate Intelligence Unit (ECIU), stated in a statement that the government need to “live to the risk of gas market lobbying triggering it to dedicate too heavily to blue hydrogen therefore keeping the country locked into fossil fuel-based innovation”.

In the example selected for the assessment, gas routes where CO2 capture rates are below around 85% were excluded..

The figure listed below from the consultation, based on this analysis, reveals the impact of setting a limit of 15-20gCO2e per megajoule (MJ) of hydrogen (red bar). In this example, those production techniques above the red line, consisting of some for producing blue hydrogen, would be excluded.

This opposition came to a head when a recent study led to headings stating that blue hydrogen is “worse for the climate than coal”.

” If we desire to show, trial, start to commercialise and after that roll out the usage of hydrogen in industry/air travel/freight or any place, then we require enough hydrogen. We cant wait till the supply side deliberations are complete.”.

The former is basically zero-carbon, but the latter can still lead to emissions due to methane leaks from gas facilities and the truth that carbon capture and storage (CCS) does not record 100% of emissions..

The strategy keeps in mind that, sometimes, hydrogen used electrolysers “could become cost-competitive with CCUS [carbon storage, capture and utilisation] -allowed methane reformation as early as 2025”..

Prof Robert Gross, director of the UK Energy Research Centre, tells Carbon Brief that, in his view, it is “most likely a bit unhelpful to get too preoccupied with the blue vs green hydrogen argument”. He says:.

There was considerable pushback on this conclusion, with other scientists– including CCC head of carbon spending plans, David Joffe– pointing out that it relied on very high methane leakage and a short-term procedure of international warming capacity that emphasised the impact of methane emissions over CO2.

At the heart of lots of discussions about low-carbon hydrogen production is whether the hydrogen is “green” or “blue”.

In May, S&P Global Platts reported that Rita Wadey– hydrogen economy deputy director at the Department for Business, Energy & & Industrial Strategy (BEIS)– stated that, instead of “blue” or “green”, the UK would “think about carbon intensity as the main aspect in market development”.

Supporting a variety of projects will offer the UK a “competitive advantage”, according to the government. Germany, by contrast, has stated it will focus exclusively on green hydrogen.

CO2 equivalent: Greenhouse gases can be revealed in terms of carbon dioxide equivalent, or CO2eq. For an offered quantity, different greenhouse gases trap various amounts of heat in the atmosphere, an amount understood as the global warming potential. Co2 equivalent is a way of comparing emissions from all greenhouse gases, not simply carbon dioxide.

The strategy mentions that the percentage of hydrogen provided by particular innovations “depends upon a series of assumptions, which can only be checked through the marketplaces response to the policies set out in this strategy and real, at-scale deployment of hydrogen”..

The new strategy mainly avoids utilizing this colour-coding system, but it states the federal government has actually devoted to a “twin track” approach that will include the production of both ranges.

Quick (hopefully) assessing this blue hydrogen thing. Basically, the papers calculations possibly represent a case where blue H ₂ is done truly severely & & without any sensible regulations. And after that cherry-picked an environment metric to make it look as bad as possible. https://t.co/Jx0FdDfdx5— David Joffe (@david_joffe) August 13, 2021.

The document does not do that and instead says it will supply “additional detail on our production strategy and twin track method by early 2022”.

The chart below, from a document detailing hydrogen expenses released along with the main method, reveals the anticipated declining cost of electrolytic hydrogen in time (green lines). (This includes hydrogen made using grid electricity, which is not technically green unless the grid is 100% sustainable.).

Glossary.

As it stands, blue hydrogen made using steam methane reformation (SMR) is the least expensive low-carbon hydrogen offered, according to government analysis consisted of in the technique. (For more on the relative costs of various hydrogen ranges, see this Carbon Brief explainer.).

The CCC has actually previously stated that the government needs to “set out [a] vision for contributions of hydrogen production from various paths to 2035” in its hydrogen technique.

Environmental groups and many researchers are sceptical about blue hydrogen provided its associated emissions.

It has likewise launched an accompanying report, prepared by consultancies E4Tech and Ludwig-Bölkow-Systemtechnik (LBST), which examines optimum appropriate levels of emissions for low-carbon hydrogen production and the methodology for computing these emissions.

The CCC has previously defined “appropriate emissions reductions” for blue hydrogen compared to fossil gas as “at least 95% CO2 capture, 85% lifecycle greenhouse gas cost savings”.

For its part, the CCC has recommended a “blue hydrogen bridge” as a beneficial tool for attaining net-zero. It says permitting some blue hydrogen will reduce emissions faster in the short-term by replacing more nonrenewable fuel sources with hydrogen when there is inadequate green hydrogen available..

The government has actually released a consultation on low-carbon hydrogen requirements to accompany the method, with a pledge to “finalise design elements” of such standards by early 2022.

How will hydrogen be used in various sectors of the economy?

” As the strategy confesses, there will not be considerable amounts of low-carbon hydrogen for some time. [] we require to use it where there are few alternatives and not as a like-for-like replacement of gas,” Dr Jan Rosenow, director of European programmes at the Regulatory Assistance Project, in a declaration.

Dedications made in the brand-new strategy consist of:.

Coverage of the report and government advertising materials emphasised that the governments strategy would provide adequate hydrogen to replace natural gas in around 3m houses each year.

Juliet Phillips, senior policy consultant and UK hydrogen professional at thinktank E3G informs Carbon Brief the method had “exposed” the door for uses that “dont add the most worth for the climate or economy”. She adds:.

It includes prepare for hydrogen heating trials and consultation on “hydrogen-ready” boilers by 2026.

Some applications, such as industrial heating, may be essentially impossible without a supply of hydrogen, and many specialists have actually argued that these hold true where it ought to be prioritised, at least in the short-term.

Michael Liebrich of Liebreich Associates has organised making use of low-carbon hydrogen into a “ladder”, with existing applications– such as the chemicals market– given top concern.

However, in the real report, the federal government stated that it expected “overall the need for low carbon hydrogen for heating by 2030 to be relatively low (<< 1TWh)".. One notable exemption is hydrogen for fuel-cell automobile. This is consistent with the governments focus on electric vehicles, which many researchers deem more efficient and cost-efficient technology. The CCC does not see comprehensive usage of hydrogen outside of these minimal cases by 2035, as the chart listed below shows. The government is more optimistic about the usage of hydrogen in domestic heating. Its analysis suggests that as much as 45TWh of low-carbon hydrogen might be put to this usage by 2035, as the chart below shows. Illustrative hydrogen demand in 2030 (blue) and 2035 (purple). Source: UK hydrogen technique. The new strategy is clear that industry will be a "lead alternative" for early hydrogen usage, starting in the mid-2020s. It also states that it will "likely" be very important for decarbonising transport-- especially heavy goods automobiles, shipping and aviation-- and stabilizing a more renewables-heavy grid. Although low-carbon hydrogen can be utilized to do whatever from fuelling cars and trucks to heating homes, the reality is that it will likely be restricted by the volume that can probably be produced. My lovelies, I just dropped Version 4 of the Clean Hydrogen Ladder! For anybody new to all this, the ladder is my effort to put usage cases for tidy hydrogen into some sort of benefit order, due to the fact that not all use cases are similarly likely to prosper. 1/10 pic.twitter.com/I8HpqQjlKS— Michael Liebreich (@MLiebreich) August 15, 2021. Call for evidence on "hydrogen-ready" industrial equipment by the end of 2021. Require proof on phaseout of carbon-intensive hydrogen production in industry "within a year". Stage 2 of the ₤ 315m Industrial Energy Transformation Fund.A ₤ 55 million Industrial Fuel Switching 2 competition in 2021. The committee emphasises that hydrogen use must be limited to "locations less suited to electrification, particularly shipping and parts of market" and supplying flexibility to the power system. This remains in line with the CCCs suggestion for its net-zero path, which sees low-carbon hydrogen scaling approximately 90TWh by 2035-- around a third of the size of the existing power sector. Government analysis, included in the strategy, suggests prospective hydrogen need of approximately 38 terawatt-hours (TWh) by 2030, not consisting of blending it into the gas grid, and increasing to 55-165TWh by 2035. Nevertheless, the technique also consists of the choice of utilizing hydrogen in sectors that might be better served by electrification, particularly domestic heating, where hydrogen needs to take on electric heatpump.. However, the starting point for the range-- 0TWh-- recommends there is significant uncertainty compared to other sectors, and even the greatest price quote is only around a 10th of the energy currently utilized to heat UK houses. " Stronger signals of intent could steer personal and public financial investments into those locations which include most worth. The government has not plainly set out how to pick which sectors will take advantage of the preliminary organized 5GW of production and has rather mostly left this to be determined through trials and pilots.". Reacting to the report, energy scientists pointed to the "small" volumes of hydrogen anticipated to be produced in the future and urged the government to select its priorities thoroughly. 4) On page 62 the hydrogen technique mentions that the government anticipates << 1 TWh of energy for heating to come from hydrogen by 2030. Present energy need in the UK for space and warm water heating is 435 TWh according to Ofgem. So 1 TWh is 0.2%. Thats about 67,000 houses.-- Jan Rosenow (@janrosenow) August 17, 2021. " I would suggest to opt for these no-regret options for hydrogen need [in market] that are currently offered ... those should be the focus.". Much will depend upon the development of expediency research studies in the coming years, and the federal governments upcoming heat and structures technique might likewise offer some clearness. Gniewomir Flis, a project supervisor at Agora Energiewende, tells Carbon Brief that-- in his view-- blending "has no future". He describes:. Finally, in order to create a market for hydrogen, the government states it will examine mixing approximately 20% hydrogen into the gas network by late 2022 and aim to make a decision in late 2023. How does the government plan to support the hydrogen industry? The new hydrogen technique verifies that this business model will be settled in 2022, making it possible for the very first agreements to be designated from the start of 2023. This is pending another consultation, which has actually been released alongside the primary technique. According to the federal governments press release, its favored design is "developed on a similar premise to the overseas wind agreements for distinction (CfDs)", which considerably cut expenses of new overseas wind farms. " This will provide us a much better understanding of the mix of production technologies, how we will satisfy a ramp-up in need, and the role that new innovations could play in accomplishing the levels of production needed to satisfy our future [6th carbon budget plan] and net-zero commitments.". Hydrogen demand (pink location) and percentage of last energy consumption in 2050 (%). My lovelies, I simply dropped Version 4 of the Clean Hydrogen Ladder! Call for proof on phaseout of carbon-intensive hydrogen production in market "within a year"." As the method admits, there wont be considerable amounts of low-carbon hydrogen for some time. 4) On page 62 the hydrogen strategy specifies that the government anticipates << 1 TWh of energy for heating to come from hydrogen by 2030. Sharelines from this story. Much of the resulting press protection of the hydrogen strategy, from the Financial Times to the Daily Telegraph, concentrated on the prepare for a hydrogen industry "subsidised by taxpayers", as the cash would come from either higher expenses or public funds. These contracts are designed to get rid of the cost gap between the preferred innovation and nonrenewable fuel sources. Hydrogen manufacturers would be given a payment that bridges this gap. Now that its method has actually been published, the federal government states it will collect proof from assessments on its low-carbon hydrogen standard, net-zero hydrogen fund and the company model:. The 10-point strategy included a pledge to develop a hydrogen service design to motivate personal investment and an earnings system to offer funding for business model. However, Anne-Marie Trevelyan-- minister for energy, clean growth and climate modification at BEIS-- informed the Times that the expense to provide long-term security to the market would be "extremely little" for specific households. As it stands, low-carbon hydrogen remains pricey compared to nonrenewable fuel source alternatives, there is uncertainty about the level of future demand and high dangers for business aiming to go into the sector.
