Loads of insightful dialogue occurred throughout the whole session which generated loads of curiosity among the many attendees. On this article, we’ve lined all of the vital questions that had been raised by the webinar attendees and the responses offered by the panelists. 

Q1) Within the development gear trade, there’s a lack of a hydrogen refueling community and potential competitors from electrical machines (excavators). Will it damage the long-term prospects of the worldwide hydrogen gasoline cell machine market? 

Reply: BIS Analysis doesn’t assume that the potential competitors from electrical machines (excavators) will damage the worldwide hydrogen gasoline cell market’s long-term prospects, particularly for the development and heavy gear trade. The important thing cause is that a number of structural points restrict makes an attempt to extend battery capability when hydrogen gasoline cells are in comparison with lithium battery applied sciences. Alternatively, hydrogen gasoline cells are simpler to broaden, making them a logical resolution for excavators. Additional a number of excavator producers, corresponding to JCB, SANY, and Hyundai Building Gear, are already testing or planning to put money into hydrogen-powered development equipment.

Q2) Since applied sciences corresponding to anion-exchange membrane (AEM) and strong oxide electrolyzer are presently getting used at a smaller scale for producing inexperienced hydrogen, what could be the important thing enchancment areas for these applied sciences for his or her adoption charges to extend?

Reply: AEM and strong oxide electrolyzer are toddler applied sciences in comparison with alkaline electrolyzer and proton trade membrane electrolyzer, leaving ample house for additional analysis and improvement.

A very powerful a part of the AEM electrolyzer is the AEM stack, the place the water-splitting response takes place. The one cell is separated into two half components by anion trade membrane. Every half-part consists of a gasoline diffusion layer (GDL), electrode, and bipolar plate. Much like the normal alkaline electrolyzer, the primary a part of the AEM electrolyzer permits hydrogen and oxygen to be produced beneath 35 bar and 1 bar stress ranges. The opposite half a part of the cell prevents produced oxygen from passing over the high-pressure half half. Thus, AEM should effectively permit hydroxide anions emigrate from the cathode to the anode and be certain that high-purity hydrogen is produced. In different phrases, AEM separates the 2 compartments and prevents the crossover of merchandise and reagents. Therefore, AEM have to be: (i) mechanically secure; (ii) thermally secure; (iii) chemically secure; (iv) ionically conductive; (v) electrochemically secure, and to make it extra helpful for at the moment’s functions, it additionally must be low price, straightforward to course of and produced by sustainable processes.

A number of know-how suppliers and analysis establishments are engaged in growing superior AEM know-how to reinforce the effectivity of the general course of. For example, in September 2022, the Korean Institute of Supplies Science (KIMS) succeeded in growing non-precious metal-based high-efficiency and sturdy anion trade membrane water electrolysis know-how. Additional, Honeywell Worldwide Inc. additionally developed a brand new catalyst-coated membrane (CCM) know-how in March 2022 for the manufacturing of inexperienced hydrogen. Honeywell is specializing in CCM know-how for use within the anion trade membrane and proton trade membrane (PEM).

An space the place a strong oxide electrolyzer is often thought to want additional enchancment is its vulnerability to degradation from excessive working temperatures. The comparatively excessive price and sophisticated fabrication are additionally substantial points that have to be thought-about.

Q3) What financial elements could make a location possible for processing the involved applied sciences? We see that in Iceland, for instance, there’s a strategic state of affairs that enhances the manufacturing of methanol with hydrogen produced utilizing renewable electrical energy, as electrical energy prices are significantly decrease.

Reply: Electrical energy price is the important thing consideration to make the method possible, and therefore Iceland is an effective selection. Nonetheless, the benefit of manufacturing methanol from inexperienced hydrogen is that it’s a globally traded commodity with a well-established world distribution community. This enables for finding the manufacturing services the place the price of making inexperienced hydrogen is most economical; usually, that is in areas far-off from most important markets. With the declining value of electrical energy manufacturing from renewable vitality sources corresponding to wind and photo voltaic, it’s possible to provide e-methanol not solely in Iceland but in addition in lots of locations worldwide. 

This autumn) What firms would undertake strategic actions or developments to lower the prices of inexperienced hydrogen within the upcoming decade? 

Reply: In at the moment’s state of affairs, the absolute best resolution for firms to reduce the price of inexperienced hydrogen manufacturing will probably be commercializing inexperienced hydrogen. Dashing up each potential commercialization venture will assist producers to cut back working prices. Additional, the developments in manufacturing applied sciences are anticipated to decrease the fee burden in upcoming years. 

Q5) At present, inexperienced methanol is majorly getting used as a gasoline; what could be the rising utility areas of inexperienced methanol within the upcoming years?

Reply: Inexperienced methanol could be utilized as a supply of feedstock to fabricate quite a lot of chemical compounds, corresponding to formaldehyde and acetic acid, that are additional utilized in foams, adhesives, solvents, plywood subfloors, washer fluid, windshields, and many others. Lately, it has additionally been more and more utilized in ethylene and propylene.
Inexperienced methanol is more and more utilized in rising trade sectors, together with development, electronics, paints, and others. Inexperienced methanol is used to fabricate development supplies corresponding to adhesives, paint, and plywood for the constructing and development trade.

Direct methanol gasoline cells (DMFCs) are useful resulting from their low temperature and atmospheric stress operations, which permit them to be miniaturized to an distinctive diploma. Mixed with the comparatively straightforward and protected storage and dealing with of methanol, DMFCs might open the opportunity of gasoline cell-powered digital gadgets corresponding to laptops, computer systems, and cell phones.

Q6) In some components of the world, water is scarce. As inexperienced hydrogen manufacturing is estimated to extend, what applied sciences aside from desalination will probably be obtainable to maintain this demand? 

Reply: BIS Analysis analyzed that to provide a kilogram of hydrogen, 9 kg of water is consumed. This can be a concern with respect to the usage of water and the shortage of freshwater. Producing round 2.3 Gt of hydrogen requires about 20.5 Gt or 20.5 billion cubic meters of freshwater per yr. That is only one.5 ppm of freshwater obtainable on Earth. In lots of functions, hydrogen have to be combusted by means of gasoline cells, which convert hydrogen gasoline into water and electrical energy. As a lot of the water will probably be recovered, it is not going to typically return to the unique water our bodies and be handled as consumed. Moreover, within the coming years, most inexperienced hydrogen will probably be produced based mostly on renewable vitality sources corresponding to wind and photo voltaic. 

Q7) Whenever you talked about that Rolls Royce just lately examined hydrogen-based plane, is it liquid or gaseous? 

Reply: The aviation trade is trying towards using a number of sustainable aviation fuels (SAFs) to reduce the carbon footprint. Not too long ago Rolls Royce and easyJet carried out a floor take a look at for inexperienced hydrogen within the aero engine. Nonetheless, this can be a pilot venture, and Rolls Royce has not but shared this data, however liquid hydrogen remains to be not utilized in airports.

Q8) Liquified and gaseous types of inexperienced H2 and coproduct storage and transportation are nonetheless essentially the most outstanding challenges as a result of lack of devoted infrastructure since they incur large prices, which is essential for export markets corresponding to Japan, South Korea, the Center East, and Europe. How can this have an effect on the value of inexperienced H2 ($/kg), and the way can the LCoH/LCoX price be lower down by the top of this decade? 

Reply: We agree that storage and transportation are key challenges within the inexperienced H2 financial system. There are particular choices that the trade is taking a look at, that are listed as follows –

1)    Pipeline: The development of latest devoted hydrogen pipelines and the repurposing of present pure gasoline pipelines are two choices that can be utilized. Nonetheless, repurposing pipelines is taken into account an efficient hydrogen transport different.

2)    Delivery: For very long-distance (round 3,000 km), the price of transportation by means of transport is economical. At present, potential know-how for hydrogen transport isn’t obtainable; thereby, hydrogen could be transferred with the conversion of hydrogen into its derivatives, corresponding to ammonia, together with different choices, corresponding to liquid hydrogen and liquid natural hydrogen carriers (LOHCs). In liquid hydrogen, there will probably be extra vitality losses resulting from robust cooling and compression necessities. A LOHC has a low conversion price; nevertheless, transporting this by way of transport consumes extra gasoline. Ammonia is already traded internationally, however its conversion again to nitrogen and hydrogen isn’t environment friendly, and in addition, it has not been examined for industrial scale.

3)    Vehicles: For last-mile supply, trucking is a viable resolution, owing to the supply of established infrastructure. Hydrogen could be transported both in compressed gasoline containers or within the type of LCoH.

The levelized price of hydrogen (LCoH) and levelized price of finish product (LCoX) for hydrogen are based mostly on varied parameters, corresponding to distance of transportation, diameter of pipes, and compression price. Transportation prices could be decreased by repurposing present pure gasoline pipelines, geopolitical feasibility, and technological developments, amongst others.

Q9) Which electrolyzer know-how is best and extra economical, whether or not PEM or alkaline? Do you assume builders want some subsidy or production-based incentive for inexperienced H2 and associated functions, particularly, inexperienced ammonia/metal/methanol/fertilizer/cement, such because the one launched by the U.S. by means of the Inflation Discount Act (IRA) that offers a manufacturing tax credit score of as much as $3/kg for matching the parity with different different fuels?

Reply: At present, there are completely different applied sciences available in the market; as an illustration, PEM and alkaline applied sciences. Alkaline know-how is best for mega initiatives. The principle advantage of this know-how is its liquid electrocatalyst. It negates the requirement for pricey steel supplies. Both method, we will look into the inducement for inexperienced H2 and associated functions; subsidiaries can promote the manufacturing until a sure interval. Adopting and commercializing all these different fuels are required to decrease prices. For all this, the one options are dashing up the commercialization of merchandise and technological developments and the implementation of insurance policies, together with encouraging the top customers to undertake revolutionary applied sciences.
