Reply: AEM and stable oxide electrolyzer are toddler applied sciences in comparison with alkaline electrolyzer and proton alternate membrane electrolyzer, leaving ample house for additional analysis and growth.
An important a part of the AEM electrolyzer is the AEM stack, the place the water-splitting response takes place. The only cell is separated into two half components by anion alternate membrane. Every half-part consists of a fuel diffusion layer (GDL), electrode, and bipolar plate. Just 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 strain 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 make sure 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 present’s purposes, it additionally must be low value, straightforward to course of and produced by sustainable processes.
A number of expertise suppliers and analysis establishments are engaged in creating superior AEM expertise to boost the effectivity of the general course of. For example, in September 2022, the Korean Institute of Supplies Science (KIMS) succeeded in creating non-precious metal-based high-efficiency and sturdy anion alternate membrane water electrolysis expertise. Additional, Honeywell Worldwide Inc. additionally developed a brand new catalyst-coated membrane (CCM) expertise in March 2022 for the manufacturing of inexperienced hydrogen. Honeywell is specializing in CCM expertise for use within the anion alternate membrane and proton alternate membrane (PEM).
An space the place a stable oxide electrolyzer is usually thought to wish additional enchancment is its vulnerability to degradation from excessive working temperatures. The comparatively excessive value and complex fabrication are additionally substantial points that have to be thought-about.

Reply: Electrical energy value is the important thing consideration to make the method possible, and therefore Iceland is an effective selection. Nevertheless, the benefit of manufacturing methanol from inexperienced hydrogen is that it’s a globally traded commodity with a well-established international distribution community. This permits for finding the manufacturing services the place the price of making inexperienced hydrogen is most economical; typically, that is in areas far-off from major markets. With the declining worth of electrical energy manufacturing from renewable power sources comparable 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 present’s state of affairs, the absolute best answer for firms to attenuate the price of inexperienced hydrogen manufacturing can be commercializing inexperienced hydrogen. Dashing up each potential commercialization undertaking 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) Presently, inexperienced methanol is majorly getting used as a gas; what could be the rising software 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, comparable to formaldehyde and acetic acid, that are additional utilized in foams, adhesives, solvents, plywood subfloors, washer fluid, windshields, and so forth. 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 comparable to adhesives, paint, and plywood for the constructing and development trade.
Direct methanol gas cells (DMFCs) are useful resulting from their low temperature and atmospheric strain 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 could open the opportunity of gas cell-powered digital gadgets comparable to laptops, computer systems, and cellphones.
Q6) In some components of the world, water is scarce. As inexperienced hydrogen manufacturing is estimated to extend, what applied sciences other than desalination can be out there 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 12 months. That is only one.5 ppm of freshwater out there on Earth. In lots of purposes, hydrogen have to be combusted by means of gas cells, which convert hydrogen fuel into water and electrical energy. As a lot of the water can be recovered, it won’t typically return to the unique water our bodies and be handled as consumed. Moreover, within the coming years, most inexperienced hydrogen can be produced based mostly on renewable power sources comparable to wind and photo voltaic.
Q7) While you talked about that Rolls Royce not too long ago 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 attenuate the carbon footprint. Lately Rolls Royce and easyJet carried out a floor check for inexperienced hydrogen within the aero engine. Nevertheless, this can be a pilot undertaking, and Rolls Royce has not but shared this info, however liquid hydrogen continues to be not utilized in airports.
Q8) Liquified and gaseous types of inexperienced H2 and coproduct storage and transportation are nonetheless probably the most outstanding challenges because of the lack of devoted infrastructure since they incur large prices, which is essential for export markets comparable 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 value be reduce down by the tip 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 , that are listed as follows –
1) Pipeline: The development of recent devoted hydrogen pipelines and the repurposing of present pure fuel pipelines are two choices that can be utilized. Nevertheless, repurposing pipelines is taken into account an efficient hydrogen transport different.
2) Transport: For very long-distance (round 3,000 km), the price of transportation by means of transport is economical. Presently, potential expertise for hydrogen transport isn’t out there; thereby, hydrogen may be transferred with the conversion of hydrogen into its derivatives, comparable to ammonia, together with different choices, comparable to liquid hydrogen and liquid natural hydrogen carriers (LOHCs). In liquid hydrogen, there can be extra power losses resulting from sturdy cooling and compression necessities. A LOHC has a low conversion value; nevertheless, transporting this by way of transport consumes extra gas. 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 answer, owing to the supply of established infrastructure. Hydrogen may be transported both in compressed fuel containers or within the type of LCoH.
The levelized value of hydrogen (LCoH) and levelized value of finish product (LCoX) for hydrogen are based mostly on varied parameters, comparable to distance of transportation, diameter of pipes, and compression value. Transportation prices may be decreased by repurposing present pure fuel pipelines, geopolitical feasibility, and technological developments, amongst others.
Q9) Which electrolyzer expertise is healthier 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 purposes, 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 provides a manufacturing tax credit score of as much as $3/kg for matching the parity with different different fuels?
Reply: Presently, there are completely different applied sciences available in the market; for example, PEM and alkaline applied sciences. Alkaline expertise is healthier for mega initiatives. The primary advantage of this expertise is its liquid electrocatalyst. It negates the requirement for pricey metallic supplies. Both means, we will look into the motivation for inexperienced H2 and associated purposes; 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 tip customers to undertake modern applied sciences.
