The oxidation of metals in water to produce hydrogen is an innovative and promising method for generating clean energy. This process involves using metals such as aluminum (Al), magnesium (Mg), and iron (Fe) that react with water to release hydrogen gas. Here’s a breakdown of how this works, along with the technical and chemical challenges that need to be addressed.

Why Metal Oxidation using Water for Hydrogen Production?

1. Abundant Resources: Metals such as aluminum, magnesium, and iron are among the most abundant elements in the Earth’s crust, making them readily available.
2. Localized Production: Metal oxidation can be employed for small-scale, on-site hydrogen generation, eliminating the need for hydrogen transport and storage infrastructure.
3. Carbon-Free: Unlike conventional hydrogen production methods that involve fossil fuels, metal oxidation is inherently carbon-free, with the reaction producing only hydrogen and harmless metal hydroxides as byproducts.
4. Recycling and Circular Economy: Utilizing recycled metals, particularly from post-industrial waste, scrap could provide a sustainable and cost-effective source of hydrogen, promoting a circular economy

How Metal Oxidation Works

Metal oxidation is when a metal reacts with oxygen to form metal oxides. In hydrogen production, this is often used in thermochemical cycles to help generate hydrogen from water. The metal reacts with oxygen to form a metal oxide, and then the metal oxide is used in a subsequent reaction to release hydrogen.

Basic Reaction: When metals oxidize, that is, they react with water (H₂O) to form metal hydroxides and hydrogen gas (H₂). For example, the reaction of aluminum with water can be simplified as follows:

2Al + 6H2​O → 2Al(OH)3 ​+ 3H2​

In this reaction, aluminum reacts with water to produce aluminum hydroxide and hydrogen gas. This is called as metal oxidation chemically. For Zinc:

Zn +2H2​O → Zn(OH)2​ + H2​

Electrochemical Process: The oxidation of metals can also be understood through electrochemical principles. When a metal oxidizes, it loses electrons (is oxidized) and forms metal ions. These electrons can be transferred to protons (H⁺) in the water, leading to the formation of hydrogen gas. This process can be harnessed in electrochemical cells or Fuel cells to produce hydrogen efficiently.

Metals with high potential:

• Aluminum (Al): Reacts readily with water, especially in the presence of a catalyst or at elevated temperatures.
• Magnesium (Mg): Reacts with water, producing hydrogen gas. It is a lightweight metal, making it attractive for hydrogen production.
• Iron (Fe): While less reactive than aluminum and magnesium, iron can still produce hydrogen when oxidized, especially under specific conditions.

Other promising Metals for Hydrogen Production

• Zinc (Zn): Zinc is a promising candidate for hydrogen production due to its high reactivity with water. It can produce hydrogen at room temperature and is abundant and inexpensive. Zinc-based systems can also be designed to regenerate zinc from zinc oxide, making the process potentially sustainable.
• Copper (Cu): While not as reactive as zinc, copper can still participate in hydrogen production under specific conditions. Recent research has focused on enhancing the activity of copper-based catalysts to improve hydrogen generation.
• Nickel (Ni): Nickel is another metal that can oxidize in water to produce hydrogen. It is often used in alloy form or as a catalyst to enhance the efficiency of hydrogen production.

Technical and Chemical Challenges

Despite its potential, the oxidation of metals in water for hydrogen production faces several challenges:

Passivation Layers or oxide layers:

• Problem: Many metals, especially aluminum and magnesium, form a protective oxide layer on their surface when exposed to air or water. This layer inhibits further oxidation, slowing down the reaction and reducing hydrogen production. This oxide layer can grow thicker over time, which can inhibit the metal’s reactivity and efficiency.
• Solution: Researchers are exploring methods to remove or prevent the formation of these layers, such as using catalysts or modifying the metal surface.

Catalyst Metal degradation:

This is the metal specifically used as a catalyst in the oxidation reactions for hydrogen production. Over time, as it participates in these reactions, it can degrade due to structural or compositional changes. This degradation can reduce the metal’s effectiveness in the reaction process.

Reaction Rate:

• Problem: The rate of hydrogen production can be slow, especially for metals like iron. This limits the efficiency of the process for practical applications.
• Solution: Using catalysts can significantly enhance the reaction rate. Transition metals, such as nickel or cobalt, are often added to improve the kinetics of the reaction.

Energy Input:

• Problem: Some metal oxidation processes require an initial energy input (e.g., heating) to initiate the reaction, which can reduce the overall efficiency.
• Solution: Developing methods to utilize renewable energy sources (like solar energy) to provide the necessary activation energy is an area of ongoing research.

Oxygen consumption:

Efficient oxygen transport to and from the metal surface is essential for maintaining reaction rates. Inadequate oxygen transport can slow down the process or make it less efficient.

Cost and Availability:

• Problem: The cost of metals and catalysts can be a barrier to large-scale hydrogen production. Additionally, the availability of certain metals may be limited.
• Solution: Research is focused on using more abundant and cheaper materials, as well as recycling metals from waste sources to reduce costs.

Environmental Impact:

• Problem: The extraction and processing of metals can have negative environmental impacts, including habitat destruction and pollution.
• Solution: Sustainable practices, such as using recycled metals and minimizing waste, are essential to mitigate these impacts.

Recent Developments in Metal Oxidation for Hydrogen Production

Catalyst Development: New catalysts are being developed to enhance the oxidation process. For example, researchers are investigating the use of metal nanoparticles that can improve the reaction rate and efficiency.

• Hybrid Systems: Combining metal oxidation with other hydrogen production methods, such as electrolysis or photocatalysis, is being explored to create hybrid systems that maximize hydrogen output.
• Nanostructured Materials: The use of nanostructured metals can increase surface area and improve reaction kinetics, leading to more efficient hydrogen production.

Conclusion

The oxidation of metals in water is a promising method for generating sustainable, carbon-free hydrogen. While there are technical and chemical challenges to overcome, ongoing research is focused on developing efficient catalysts, improving reaction rates, and creating hybrid systems to enhance hydrogen production. With continued advancements, this technology could play a significant role in the transition to a cleaner energy future.

While methods such as water electrolysis and natural gas reforming have traditionally been the main pathways for hydrogen production, metal oxidation in water has gained considerable attention as a sustainable and carbon-free alternative. This process, where metals such as aluminum (Al), magnesium (Mg), iron (Fe), and others react with water to produce hydrogen, offers localized and on-demand hydrogen production, without the carbon emissions linked to fossil fuels.

Why hydrogen Fuel?

Let us explore the key reasons behind using Hydrogen as a fuel in Transportation.

The global transport sector’s contribution to total CO2 emissions is close to 25%. Hence need to de-carbonize the transport sector as quickly as possible to arrest the global warming which is accelerating.

Decarbonizing transport refers to the process of reducing and eventually eliminating greenhouse gas emissions (GHG) associated with the transportation sector. This is crucial for combating climate change, as transportation is a major contributor to global CO2 and NOx emissions.

Hydrogen reacts or burns in air (with oxygen) releasing heat and water vapor only. This reaction highlights that no carbon containing products or CO/CO2 emissions at the point of use. No other green house gases (GHG). Here it is assumed complete burn or complete oxidation at normal temperature and pressure. Burning hydrogen at high pressure, high temperature in closed chamber results in production of NOx gases. However no CO/CO2 is produced.

Similarly when hydrogen is used in a fuel cell, hydrogen generates only electricity, water, and heat when it reacts with oxygen, through an electro chemical reaction. No carbon dioxide (CO2) or no other GH gas is produced when using hydrogen in a fuel cell because no combustion happens. Thus hydrogen as a clean fuel, no harm to environment, good for the climate to sustain. This makes hydrogen a very attractive option for transportation and power generation.

Hydrogen has highest gravimetric energy density (see the table) being the primary reason for considering hydrogen as a strong contender, as an alternative among all types of fuels. In simple terms, by weight, hydrogen holds a highest amount of energy. Approximately 3 kilograms of gasoline required to provide the same amount of energy as 1 kilogram of hydrogen. This physical aspect makes hydrogen as an energy carrier as well. This makes it extremely attractive for both transportation and stationary power applications.

Challenges:

Under normal pressure and temperature conditions, 1 kg of hydrogen occupies approximately 12,000 Litres where as 1 kg of gasoline = 1.34 Litres.

You can now imagine!

Due to its extremely low density, hydrogen in gaseous form takes up huge volume at normal atmospheric pressure. That is by volumetric energy density, hydrogen is the lowest among all. Hence for all practical purposes of hydrogen use, it has to be compressed or liquefied, this is the major roadblock in using hydrogen in transportation other than hydrogen is highly flammable and can ignite easily in normal conditions.

Hence in mobility applications like heavy duty, long haul transport, hydrogen storage requirements can significantly limit passenger and cargo space. Similarly, in passenger vehicles, there’s a trade-off between passenger space, comfort and range.

Reasons for considering Hydrogen as an alternative fuel, comparing with Battery electric vehicles (BEV):

It’s suitable for larger vehicles where battery weight could be prohibitive.

Heavy-duty transport is the ideal use case for hydrogen. The long-range capabilities and fast refueling mean they can match and exceed the performance of diesel trucks, while producing zero emissions at the tailpipe.

For long haul trucking, hydrogen provide a potential answer that could balance distance coverage, weight, and refueling duration. They have the capability to offer a range similar to that of diesel trucks and can be refueled less than 15 minutes. (using Liquid Hydrogen).

There are only two approaches for utilizing hydrogen fuel in transportation.

Hydrogen internal combustion engine (H2ICE or HICE):

This method involves burning hydrogen directly in an internal combustion engine, same like gasoline or diesel vehicles. This combustion generates power to drive the wheels. While emissions are cleaner, near zero CO2 than fossil fuel engines, they still produce NOx (nitrogen oxides), requiring additional exhaust control technologies. We must note that no CO/CO2 emissions are produced in the combustion of hydrogen directly in the engine (except some traces of CO2 from the burned lubricants). No solid particles are produced from the combustion exhaust.

The efficiency of H2ICE is approximately in the range of 38-40% inline with that of conventional gasoline, diesel counterparts.

Hydrogen engines are entirely mechanical, same like gasoline, diesel powered vehicles today.

Hydrogen Fuel Cell based Electric Vehicle (H2FC):

Here, hydrogen from onboard storage tank is converted back into electricity via a fuel cell onboard the vehicle. This generated electricity then powers the electric motor. However, due to energy losses during the conversion process (assuming green hydrogen is used), FCEVs require roughly 2.3 times more electricity to operate compared to battery electric vehicles. No mechanical or combustion process is involved as fuel cell, produces electricity through an electrochemical reaction.

Fuel cell based vehicles are pure zero emission vehicles (ZEV) as no CO2, NOx, unburnt fuels or solid particles are emitted, because there is no combustion or burning at all!

Onboard hydrogen storage challenges remains the same as that of H2ICE powered. There’s a trade-off between space and range.

Relative strengths of H2ICE and H2FC:

Heavy Commercial vehicles (HCV) of significant weight are often required to have extensive range and high-power capabilities. As such, HCVs, including long-haul trucks (LH), are prime candidates for hydrogen based. The hydrogen combustion engine (Hydrogen engines) presents a promising alternative to battery electric and fuel cell electric vehicles, contributing to the goal of a carbon dioxide-free commercial vehicle industry.

Potential Cost Advantage: H2ICE vehicles are cost-effective alternative to fuel cell vehicles, due to their simpler technology and adaptation of existing (gasoline) engine infrastructure.

H2ICEs could leverage the existing network of gas stations, thus easing the smooth transition to hydrogen fuel.

H2FC boast high efficiency (in terms of Fuel Tank Hydrogen to electricity), strictly zero emissions in par with a battery electric vehicle (BEV). However the cost is very high, and a very complex system, however intensive R&D is happening across to overcome the issues and huge cost associated.

.Hydrogen fuel in transportation is still in its infancy. However both H2FCV and H2ICE, have the potential to revolutionize the automotive industry by providing sustainable and eco-friendly transportation solutions.

What is Tri-gen?

The Tri-gen system, owned and operated by FuelCell Energy, produces three products: renewable electricity, renewable hydrogen, and usable water. This is achieved using renewable biogas supplied through a pipeline to the facility. Biogas is produced from organic waste or sewage water.

Tri-gen is expected to help

• To reduce more than 9,000 tons of CO₂ emissions from the power grid each year
• To reduce diesel consumption by more than 420,000 gallons per year, using hydrogen-powered fuel cell Class 8 trucks in port operations
• To avoid more than six tons of grid NOx emissions

The clean energy system produces 2.3-megawatts of renewable electricity. Part of this will be utilized by TLS Long Beach to support its 100% operations at the port. This is the Toyota’s first logistics facility, powered by onsite generated, 100 percent renewable energy.

Surplus electricity generated is supplied to the local utility company, Southern California Edison. This is in accordance with the California Bioenergy Market Adjustment Tariff (BioMAT) program. Hence contributing a renewable, robust, and cost-effective baseload electricity generation resource to the power grid.

The new system can generate up to 1,400 gallons of water daily. This water is then repurposed for the car wash operations at TLS for vehicles arriving at the port prior to delivery to customers. This practice aids in decreasing the strain on local water supplies by saving around half a million gallons annually.

The high level technology behind

Renewable Biogas primarily consists of methane gas. And methane (from Natural gas) is used for the production of hydrogen commercially through a well known industry process called steam methane reforming (SMR) process.

Internal reforming using fuel cells is the cutting-edge technology that holds promise for direct hydrogen production from natural gas within the fuel cell itself. This is achieved by a special electrocatalyst embedded in the fuel electrode’s porous structure. The internally produced hydrogen and carbon monoxide (via in-situ steam reforming) are immediately consumed by the cell through electrochemical process generating clean electricity, water vapour at the output. Initial calculations suggest this technology offers very high conversion rates (potentially 100%) due to the continuous removal of hydrogen for direct power generation.

This fuel cell based technology is a highly efficient, combustion-free process that emits virtually no air pollutants.

Fuel cell type: High temperature, Carbonate Fuel Cell

Tri-gen system has the capacity to generate up to 1,200 kg of hydrogen per day. This hydrogen is used to fuel Toyota’s incoming light-duty fuel cell electric vehicle (FCEV) Mirai and also to supply hydrogen to the nearby heavy-duty hydrogen refueling station. This supports the logistics and drayage operations of TLS at the port.

Starting from January 1, 2024, California’s Advanced Clean Fleet Regulation will permit only zero-emission trucks to register as new drayage trucks. By the year 2035, it will be mandatory for all drayage trucks to be zero-emission. The Tri-gen platform is already supporting FCEV Class 8 trucks and is prepared to aid the ongoing transition to zero-emission trucks up until 2035.

The production of hydrogen can be adjusted based on the demand. After the construction of the Tri-gen system was completed last year, Toyota used the renewable hydrogen produced to fuel the first Toyota Mirai vehicles at TLS in January of this year. In April, the first heavy-duty FCEV Kenworth T680 Class 8 truck was fueled at the adjacent Shell HD filling station using renewable hydrogen produced by Tri-gen.

Statements from Toyota and FuelCell Energy

Chris Reynolds, Chief Administrative Officer, Toyota, said, “By utilizing only renewable hydrogen and electricity production, TLS Long Beach will blaze a trail for our company1. Working with FuelCell Energy, together we now have a world-class facility that will help Toyota achieve its carbon reduction efforts.”

FuelCell Energy CEO Jason Few said, “FuelCell Energy is committed to helping our customers surpass their clean energy objectives. By working with FuelCell Energy, Toyota is making a powerful statement that hydrogen-based energy is good for business, local communities, and the environment.”

Conceptualized in October 2019, Mercedes-Benz GenH2 Trucks, powered by liquid hydrogen based fuel cells, have undergone rigorous testing on both test tracks and public roads. Daimler Truck is taking the next step by building a first customer-trial fleet of these hydrogen-powered trucks. Now companies like Amazon, Air Products, INEOS, Holcim, and Wiedmann & Winz are participating in these trials, gaining initial experience in CO2-free long-distance transport.

The company aims to introduce the series version of the Mercedes-Benz GenH2 Truck in the second half of the decade, 2027.

The Mercedes-Benz GenH2 Trucks

• GenH2 Trucks inherit characteristics of the conventional Mercedes-Benz Actros long-haul truck in terms of payload, range and performance

• Hydrogen Fuel Cell System from cellcentric, a cutting-edge fuel-cell system that operates in a parallel hybrid configuration. This system combines the benefits of both hydrogen fuel cells and a battery to optimize efficiency and power delivery.

• The fuel cells generate a total power output of 300 kilowatts (kW) (equivalent to 2x 150 kW) .
• The battery, with a capacity of 70 kilowatt-hours (kWh), provides additional power when needed, reaching up to 400 kW temporarily
• At 70 kWh, the storage capacity of the battery is relatively low, as it is not intended to meet energy needs, but mainly to be switched on to provide situational power support for the fuel cell, for example during peak loads while accelerating or while driving uphill fully loaded. At the same time, the relatively light battery allows a higher payload. It is recharged with braking energy and excess fuel-cell energy.
• Daimler Truck prefers liquid hydrogen ( -253 degree C) in the development of hydrogen-based drives
• Two stainless-steel liquid-hydrogen tanks carry a total of 88 kilograms of liquid hydrogen (44 kg each). The stainless-steel tank system consists of two tubes, one within the other, that are connected to each other, and vacuum insulated.
• Electric Motors: In a pre-series version, the two electric motors are designed for a total of 2 x 230 kW continuous power and 2 x 330 kW maximum power.
• Range and Payload: The GenH2 Trucks offer an impressive range of up to 1,047 kilometers (approximately 620 miles) on one fill of liquid of hydrogen , that is 88kg of hydrogen. Thus 1047 KM per 88 kg of H2.
• They can carry a substantial payload up to 25 tons (50,000 pounds)with a gross vehicle weight of 40 tons (80,000 pounds).
• The semi-trailer tractors will operate on specific routes in Germany, transporting materials such as building supplies, sea containers, and cylinder gases.
• During these trials, the GenH2 Trucks will be refueled at designated public liquid hydrogen filling stations in Wörth am Rhein and the Duisburg area.
• For the first time, a new refueling process for liquid hydrogen will be used in the customer-trial fleet: the so-called “sLH2 technology” (sLH2 = “subcooled” liquid hydrogen). The technology was developed jointly with Linde and is freely available to all interested companies via an ISO standard.
• The innovative approach enables, among other things, an even higher storage density compared to LH2 and easier refueling within 10–15 minutes.
• These trucks represent a significant step toward CO₂-free long-distance transport and showcase the potential of hydrogen as a clean energy source for heavy-duty vehicles .
