A brand new report gives an summary of the hydrogen worth chain, together with an appraisal of various manufacturing strategies, distribution and the place the authors imagine will probably be used. Market initelligence agency IDTechX writes
Decarbonization efforts have gained momentum globally in recent times. Renewable vitality, electrification, and battery storage are major options. Nonetheless, some sectors stay troublesome to decarbonize utilizing such strategies, together with heavy trade, heating, and sure transport sectors, reminiscent of aviation and delivery. Hydrogen gives a promising resolution for these difficult sectors. Its potential as a gasoline, vitality provider, and chemical feedstock has led to many governments formulating nationwide hydrogen methods. Consequently, corporations are seizing market alternatives, supplying a spread of companies, merchandise, and applied sciences. The burgeoning hydrogen market is drawing consideration from stakeholders globally.
A cohesive worth chain is crucial for realizing hydrogen’s potential, encompassing low-carbon hydrogen manufacturing, storage, and distribution infrastructure, which align with end-user demand. Analogous to the oil & gasoline sector, the hydrogen worth chain contains upstream (manufacturing), midstream (storage & transport), and downstream (end-use) segments. Every section poses distinctive technical and socio-economic challenges. The report “Hydrogen Economic system 2023-2033: Manufacturing, Storage, Distribution & Purposes” analyzes many of those points.

Hydrogen economic system: Standing vs ambition
At the moment, over 98% of worldwide hydrogen originates from fossil fuel-based gray and black hydrogen, produced utilizing steam methane reforming and coal gasification. These strategies considerably contribute to CO2 emissions. In response, quite a few corporations are pioneering low-carbon hydrogen manufacturing methods, specializing in blue hydrogen (pure gasoline reforming with CO2 seize) or inexperienced hydrogen (water electrolysis utilizing renewable vitality).
The vitality transition necessitates new low-carbon hydrogen amenities. Consequently, governments are establishing definitive manufacturing targets for upcoming years. As an example, the UK targets 10GW of low-carbon hydrogen by 2030 (2.5 million tonnes of blue H2 yearly, 5GW inexperienced H2), whereas the US goals for 10 million tonnes yearly. A number of different nations even have bold manufacturing targets. Nonetheless, the tempo of recent manufacturing web site challenge announcement and improvement lags behind these targets as a result of excessive prices of manufacturing (particularly for inexperienced H2), lack of supporting renewable and CCUS infrastructure, lengthy lead occasions to creating closing funding selections, in addition to challenges in securing financing and allowing. Coupled with an inadequate midstream storage and distribution community, there may be an immense alternative for improvement and innovation in each expertise and infrastructure throughout the worth chain.
Blue hydrogen manufacturing applied sciences
At the moment, blue hydrogen, derived from pure gasoline, is probably the most cost-effective low-carbon hydrogen manufacturing technique, having an estimated levelized value of hydrogen (LCOH) of round US$2-4/kg H2. As compared, inexperienced hydrogen has a a lot larger LCOH at US$4-10/kg H2, relying on the manufacturing technique and regional elements like renewable vitality availability. Thus, blue hydrogen is seen as a transitional resolution till inexperienced hydrogen turns into commercially viable.
A number of applied sciences can produce blue hydrogen. Essentially the most prevalent is steam methane reforming (SMR). Different scalable strategies utilizing methane have emerged, such because the partial oxidation (POX) course of, which transforms waste hydrocarbon feedstocks into worthwhile syngas and is utilized in some refineries globally. One other notable technique is autothermal reforming (ATR), a hybrid of SMR and POX.
ATR is favored for its vitality effectivity and compatibility with carbon seize applied sciences, essential for cost-efficient blue hydrogen manufacturing. Noteworthy initiatives using ATR embrace Air Merchandise’ Internet-Zero Hydrogen Power Complicated in Alberta, leveraging Topsoe’s SynCOR expertise. IDTechEx anticipates SMR, POX, and ATR to steer the blue hydrogen sector within the coming decade, with ATR doubtlessly dominating new manufacturing capability by 2034. Extra on such subjects, in addition to novel reforming applied sciences, reminiscent of methane pyrolysis and electrified SMR, is offered in IDTechEx’s “Blue Hydrogen Manufacturing & Markets 2023-2033: Applied sciences, Forecasts, Gamers” report.
Inexperienced hydrogen manufacturing applied sciences
Inexperienced hydrogen, produced by way of water electrolysis powered by renewable vitality, is garnering important curiosity. A number of applied sciences exist for its manufacturing. Essentially the most established is the alkaline water electrolyzer (AWE), which makes use of a potassium hydroxide (KOH) alkaline electrolyte. Benefiting from reasonably priced building and catalytic supplies like nickel and metal, AWE boasts decrease capital prices than its counterparts. Nonetheless, its dynamic operability is poor, and its effectivity is low below atmospheric strain. Therefore, pressurized AWEs have emerged in the marketplace, with most gamers supplying such methods.
The proton trade membrane electrolyzer (PEMEL) is the most well-liked expertise as it might probably combine extraordinarily nicely with renewables and comply with their profile, ramping manufacturing up or down inside minutes. This expertise has a special construct and working precept to the AWE, utilizing polymer membranes, primarily Nafion, because the electrolyte. The draw back is its dependency on platinum group metallic (PGM) electrocatalysts, notably iridium oxide on the anode – iridium is a pricey and scarce mineral. Consequently, minimizing PGM use and growing various catalysts is a key trade focus.
Different applied sciences embrace the stable oxide electrolyzer (SOEL), using a ceramic electrolyte, and the anion trade membrane electrolyzer (AEMEL), which goals to merge some great benefits of AWE and PEMEL. Nonetheless, IDTechEx predicts AWE and PEMEL will lead the market within the coming decade as a result of their established presence. Reducing electrolyzer plant prices (CAPEX/OPEX), working large-scale crops, and increasing electrolyzer manufacturing capability is crucial for the long run. Nonetheless, entry to reasonably priced renewable electrical energy will in the end decide inexperienced hydrogen’s success. Extra on such subjects, in addition to detailed evaluation of the electrolyzer market and gamers, is offered in IDTechEx’s “Inexperienced Hydrogen Manufacturing: Electrolyzer Markets 2023-2033” report.
