20 min readFeb 12, 2024

Introduction

Coal gasification is a process that converts coal into synthesis gas (syngas), which is a mixture of carbon monoxide (CO) and hydrogen (H2), along with other gases such as carbon dioxide (CO2) and methane (CH4). The syngas produced through coal gasification can be used as a feedstock for the production of various chemicals, fuels, and energy products, including hydrogen.

Here’s a detailed overview of the coal gasification process and the subsequent production of hydrogen:

Coal Preparation: The coal used in the gasification process is typically pulverized into fine particles to increase its surface area and improve its reactivity. This pulverized coal is then mixed with water to form a coal-water slurry, which is easier to handle and feed into the gasifier.
Gasification: The coal-water slurry is fed into a gasifier, which operates at high temperatures (typically between 700°C to 1,500°C) and pressures. In the gasifier, the coal undergoes a series of chemical reactions in the presence of a controlled amount of oxygen (O2) and steam (H2O). These reactions result in the breakdown of the coal into syngas, which primarily consists of carbon monoxide (CO) and hydrogen (H2), along with other gases such as carbon dioxide (CO2) and methane (CH4).
Syngas Cleanup: The raw syngas produced from the gasifier contains impurities such as sulfur compounds, particulate matter, and trace contaminants. Before further processing, the syngas is subjected to a cleanup process to remove these impurities. This typically involves processes such as sulfur removal, tar and particulate removal, and acid gas removal.
Shift Conversion: The raw syngas may undergo a shift conversion process to adjust the ratio of hydrogen to carbon monoxide in the syngas. This is typically achieved through the water-gas shift reaction, where carbon monoxide reacts with steam to produce carbon dioxide and additional hydrogen.
Hydrogen Separation: After the syngas has been cleaned and adjusted in composition, hydrogen separation processes are employed to separate hydrogen from the other gases present in the syngas stream. Common methods for hydrogen separation include pressure swing adsorption (PSA), membrane separation, and cryogenic distillation.
Hydrogen Purification: The separated hydrogen may undergo further purification steps to remove any remaining impurities and ensure high purity levels. This may involve additional purification processes such as pressure swing adsorption (PSA), membrane separation, or catalytic purification.
Hydrogen Compression: The purified hydrogen is then compressed to the desired pressure for storage, transportation, or further use. Compression increases the density of hydrogen and reduces its volume for more efficient handling and storage.
Storage and Distribution: The compressed hydrogen may be stored in tanks or cylinders for later use or distributed through pipelines or tanker trucks to end-users or industrial consumers.
Carbon Capture Unit: This critical component underscores our commitment to environmental responsibility by mitigating carbon emissions. Through a comprehensive evaluation of the technology’s implementation costs and operational efficiencies, we illustrate its pivotal role in enhancing the plant’s sustainability profile. Explore how the integration of carbon capture technology aligns with our financial objectives while advancing environmental stewardship in the blue hydrogen production process.

Overall, coal gasification followed by hydrogen production involves a series of complex chemical and physical processes aimed at converting coal into hydrogen-rich syngas, cleaning and purifying the syngas, and separating and purifying the hydrogen for various applications. This process offers a versatile and potentially cleaner alternative to traditional coal combustion for energy and chemical production.

Product costing for hydrogen production

Product costing involves determination of Fixed cost, Variable cost and cost overheads. Let us do this calculation for our 50000 kg per day capacity plant. To break down the per kg production cost into fixed cost, variable cost, and overhead components, we need to understand the nature of these costs and how they relate to the production of hydrogen through coal gasification.

Fixed Costs: Fixed costs are expenses that do not vary with the level of production. These costs remain constant regardless of the amount of hydrogen produced. Examples of fixed costs in hydrogen production might include depreciation, administrative salaries, insurance premiums, and facility rent or lease payments.
Variable Costs: Variable costs are expenses that vary with the level of production. These costs increase or decrease in direct proportion to the amount of hydrogen produced. Examples of variable costs in hydrogen production could include raw materials (e.g., coal, water), direct labor, utilities (e.g., electricity, water, natural gas), and maintenance costs.
Overhead Costs: Overhead costs are indirect expenses necessary for the operation of the plant but not directly tied to production. These costs support the overall operation and administration of the business. Examples of overhead costs in hydrogen production might include facility maintenance, security, quality control, and regulatory compliance expenses.

Estimation of Raw material:

If coal is used as the raw material for hydrogen production through coal gasification process, the primary raw material required would be coal itself. Coal gasification involves converting coal into synthesis gas (syngas), which is a mixture of hydrogen, carbon monoxide, and other gases. This syngas can then be further processed to extract pure hydrogen.

The raw materials required for coal gasification-based hydrogen production are:

Coal: This serves as the primary feedstock for the gasification process. Coal is reacted with steam (H₂O) and sometimes oxygen (O₂) or air to produce syngas through gasification reactions. The composition of the syngas depends on the gasification process parameters and the type of coal used.
Water (H₂O): Steam is typically used as a reactant in the coal gasification process to facilitate the conversion of coal into syngas. The steam reacts with carbon in the coal to produce hydrogen and carbon monoxide.

In addition to coal and water, various auxiliary materials may also be required depending on the specific design and operational requirements of the coal gasification plant. These auxiliary materials could include catalysts, sulfur removal agents, and other chemicals used for process control and environmental compliance.

It’s worth noting that coal gasification for hydrogen production is a complex process that requires careful management of operating conditions, as well as environmental and safety considerations due to the potential for emissions of pollutants such as sulfur compounds and particulate matter.

Estimation of Coal required per day

To determine the amount of coal needed for hydrogen production through coal gasification, we need to consider the stoichiometry of the gasification reaction and the desired output of hydrogen. The exact amount of coal required will depend on factors such as the composition of the coal, the efficiency of the gasification process, and any losses during the conversion process.

The general gasification reaction for coal can be represented as follows:

C + H₂O -> CO + H₂

This equation shows that one mole of carbon (C ) reacts with one mole of water (H₂O) to produce one mole of carbon monoxide (CO) and one mole of hydrogen (H₂).

Let’s proceed with the calculation based on some assumptions:

Assume the coal used has a high carbon content, typically around 80%.
Assume an ideal gasification process with no losses or inefficiencies.
Determine the stoichiometric ratio between coal and hydrogen produced.

Given these assumptions, the stoichiometric ratio between coal and hydrogen can be calculated based on the stoichiometry of the gasification reaction:

1 mole of coal produces 1 mole of hydrogen.

Since the molar mass of coal can vary significantly depending on its composition and type, we’ll use an average value of approximately 25 g/mol for our calculation.

Now, let’s calculate the amount of coal needed to produce 50,000 kg (or 50,000,000 g) of hydrogen per day:

Number of moles of hydrogen = mass of hydrogen / molar mass of hydrogen Number of moles of hydrogen = 50,000,000 g / 2 g/mol = 25,000,000 mol

Since the stoichiometric ratio between coal and hydrogen is 1:1, the number of moles of coal required is the same as the number of moles of hydrogen:

Number of moles of coal = 25,000,000 mol

Finally, we convert the number of moles of coal to mass using the molar mass of coal:

Mass of coal = number of moles of coal × molar mass of coal Mass of coal = 25,000,000 mol × 25 g/mol = 625,000,000 g = 625,000 kg

Therefore, approximately 625,000 kg of coal is needed per day to produce 50,000 kg of hydrogen through coal gasification.

To calculate the cost of coal for hydrogen production through coal gasification, we need to consider the price of coal per unit mass and multiply it by the amount of coal required per day.

Let’s assume a hypothetical price of coal in India, for example, 5,000 INR per metric ton (1 ton = 1,000 kg). Please note that actual prices may vary significantly.

Given that we calculated the amount of coal needed per day to be approximately 625,000 kg, we can proceed with the calculation:

Convert the price of coal to the same unit as the mass of coal (per kg): 5,000 INR per metric ton = 5 INR per kg
Multiply the price of coal per kg by the amount of coal required per day: Cost of coal = Price of coal per kg × Mass of coal required per day = 5 INR/kg × 625,000 kg = 3,125,000 INR per day

Therefore, based on our assumptions and hypothetical coal price, the estimated cost of coal for hydrogen production through coal gasification would be 3,125,000 INR per day.

Please note that actual coal prices can vary significantly depending on factors such as location, quality, market demand, and supply chain logistics. It’s essential to obtain up-to-date pricing information from reliable sources for accurate cost estimations.

Estimation of Water & Other Raw material required per day

To calculate the water and other raw material requirements for hydrogen production through coal gasification, we need to consider the stoichiometry of the gasification reaction and any additional chemicals or materials required for the process.

Water (H₂O): As mentioned earlier, steam (water vapor) is typically used as a reactant in the coal gasification process. The steam reacts with carbon in the coal to produce hydrogen and carbon monoxide according to the following reaction:

C + H₂O -> CO + H₂

Given that one mole of water (H₂O) is consumed per mole of hydrogen (H₂) produced, and we already calculated that 50,000 kg of hydrogen is produced per day, we can use the molar mass of water (18 g/mol) to calculate the amount of water required.

Number of moles of water = mass of hydrogen / molar mass of water = 50,000,000 g / 18 g/mol ≈ 2,777,778 mol

Therefore, approximately 2,777,778 moles of water are required per day for hydrogen production.

Other Raw Materials and Chemicals: Depending on the specific coal gasification process and operational requirements, additional raw materials and chemicals may be needed. These could include:

Oxygen (O₂) or air: In some gasification processes, oxygen or air may be used as a reactant alongside steam to facilitate the conversion of coal into syngas.
Catalysts: Certain catalysts may be used to enhance the efficiency of the gasification reaction or to promote specific chemical reactions within the gasifier.
Sulfur removal agents: Coal often contains sulfur compounds, which can lead to the formation of sulfur-containing gases during gasification. Therefore, sulfur removal agents may be required to reduce sulfur emissions and comply with environmental regulations.
Process additives: Various additives may be used to adjust the properties of the syngas or to control impurities in the gas stream.

The specific quantities of these additional materials will depend on the process design and operational parameters of the coal gasification plant. Detailed engineering studies and process simulations are typically conducted to optimize the use of these materials and ensure efficient operation of the gasification process.

Please note that the quantities provided here are based on idealized stoichiometric calculations and may vary in practice depending on factors such as process efficiency, purity requirements, and operational conditions.

Cost of Water & Other raw material required per day:

To calculate the cost of water and other raw materials for hydrogen production through coal gasification, we need to determine the prices of these materials in India and then multiply them by the quantities required per day.

Let’s assume hypothetical prices for water and other raw materials:

Water (H₂O): The cost of water can be negligible for industrial purposes, especially if it’s sourced locally or treated on-site. However, we can estimate the cost based on the price of water utilities in India. Let’s assume a hypothetical cost of 5 INR per cubic meter (1 cubic meter = 1000 liters).
Other Raw Materials and Chemicals: The prices of other raw materials and chemicals can vary widely depending on their types and suppliers. Without specific information, it’s challenging to provide accurate estimates. However, we can assume a lump-sum cost to cover these materials. Let’s assume a hypothetical cost of 10,000 INR per day for simplicity.

Now, let’s calculate the cost of water and other raw materials:

Water:

Cost of water per cubic meter = 5 INR
Volume of water required per day = 2,777,778 moles × (18 g/mol / 1000 g/L) ≈ 50,000 cubic meters
Total cost of water per day = Cost of water per cubic meter × Volume of water required per day = 5 INR/m³ × 50,000 m³ = 250,000 INR per day

Other Raw Materials and Chemicals:

Total cost of other raw materials and chemicals per day = 10,000 INR

Therefore, the estimated total cost of water and other raw materials for hydrogen production through coal gasification is:

Cost of water: 250,000 INR per day
Cost of other raw materials and chemicals: 10,000 INR per day

Please note that these are simplified estimates and actual costs may vary based on factors such as market prices, supplier agreements, and specific project requirements. It’s essential to obtain up-to-date pricing information from reliable sources for accurate cost estimations.

Fixed Cost for Coal Gasification Plant:

Let’s identify the specific expenses that contribute to fixed costs in hydrogen production through coal gasification. Here’s a breakdown of common fixed costs:

Depreciation: Depreciation expense accounts for the gradual loss in value of capital assets over their useful life. This includes equipment, machinery, and infrastructure used in the coal gasification plant.
Administrative Salaries: Salaries and wages for administrative staff responsible for managing and overseeing the operations of the plant.
Insurance Premiums: Premiums paid for insurance coverage to protect against various risks, including property damage, liability claims, and business interruption.

Maintenance Contracts: Costs associated with maintenance contracts for equipment and machinery, including routine inspections, repairs, and preventive maintenance services.
License and Permit Fees: Fees paid for various licenses, permits, and regulatory approvals required to operate the coal gasification plant.

Let’s estimate the fixed cost component for a 50000 kg per day capacity plant:

Depreciation: 500,000 INR/day
Administrative Salaries: 300,000 INR/day
Insurance Premiums: 100,000 INR/day
Rent or Lease Payments: 200,000 INR/day
Property Taxes: 100,000 INR/day
Utilities (Fixed Portion): 200,000 INR/day
Maintenance Contracts: 200,000 INR/day
License and Permit Fees: 100,000 INR/day

Now, let’s sum up these expenses to calculate the total fixed cost per day:

Total Fixed Costs = Depreciation + Administrative Salaries + Insurance Premiums + Rent or Lease Payments + Property Taxes + Utilities (Fixed Portion) + Maintenance Contracts + License and Permit Fees

Total Fixed Costs = 500,000 INR/day + 300,000 INR/day + 100,000 INR/day + 200,000 INR/day + 100,000 INR/day + 200,000 INR/day + 200,000 INR/day + 100,000 INR/day

Total Fixed Costs = 1,700,000 INR/day

Therefore, the total fixed cost component in hydrogen production through coal gasification is approximately 1,700,000 INR per day.

or fixed cost per kg of hydrogen produced = INR 1,700,000/50000 = INR 34 per kg.

Variable Cost for a Coal Gasification Plant:

To break down the variable cost component in hydrogen production through coal gasification, let’s identify the specific expenses that vary with the level of production. Here’s a breakdown of common variable costs:

Raw Materials: Expenses related to the purchase of raw materials, such as coal and water, which are directly consumed in the production process.
Direct Labor: Wages and benefits for the personnel directly involved in operating and maintaining the coal gasification plant.
Utilities (Variable Portion): Utility expenses that vary based on the level of usage, such as electricity, water, and natural gas consumed during the production process.
Maintenance and Repair Costs: Expenses for maintenance activities, including repairs and replacements of equipment and machinery, which may vary depending on the level of production and wear and tear.
Fuel Costs: Costs associated with the purchase of fuel used in the production process, such as natural gas or other fuels required for heating and processing.
Chemicals and Catalysts: Expenses for the purchase of chemicals and catalysts used in the coal gasification process to enhance efficiency or control reactions.

Let’s assume the following breakdown for the variable cost component:

Raw Materials (Coal and Water): 2,708,000 INR/day
Direct Labor: 400,000 INR/day
Utilities (Variable Portion): 320,000 INR/day
Maintenance and Repair Costs: 160,000 INR/day
Fuel Costs: 240,000 INR/day
Chemicals and Catalysts: 400,000 INR/day

Now, let’s sum up these expenses to calculate the total variable cost per day:

Total Variable Costs = Raw Materials + Direct Labor + Utilities (Variable Portion) + Maintenance and Repair Costs + Fuel Costs + Chemicals and Catalysts

Total Variable Costs = 2,708,000 INR/day + 400,000 INR/day + 320,000 INR/day + 160,000 INR/day + 240,000 INR/day + 400,000 INR/day

Total Variable Costs = 4,228,000 INR/day

Therefore, the total variable cost component in hydrogen production through coal gasification is approximately 4,228,000 INR per day.

So Variable cost per Kg Hydrogen produced = 4,228,000 INR/50000 = INR 84.56 per Kg

Indirect Cost or Cost Overhead:

To break down the overhead cost component in hydrogen production through coal gasification, let’s identify the specific expenses that support the overall operation of the plant but are not directly tied to production volume. Here’s a breakdown of common overhead costs:

Facility Maintenance: Expenses for the upkeep and maintenance of the plant’s infrastructure, including buildings, equipment, and machinery.
Security: Costs associated with security measures to protect the plant’s assets, facilities, and personnel.
Quality Control and Regulatory Compliance: Expenses related to ensuring product quality, meeting regulatory requirements, and conducting compliance activities.
Environmental Compliance: Costs associated with environmental monitoring, emissions control, and compliance with environmental regulations.
Administrative Expenses: General administrative expenses, including office supplies, communication, and other administrative overhead.
Training and Development: Costs related to employee training, skills development, and professional development programs.
Research and Development: Expenses for research and development activities aimed at improving processes, products, or technologies related to hydrogen production.

Let’s assume the following breakdown for the overhead cost component:

Security: 100,000 INR/day
Quality Control and Regulatory Compliance: 300,000 INR/day
Environmental Compliance: 100,000 INR/day
Administrative Expenses: 200,000 INR/day
Training and Development: 50,000 INR/day
Research and Development: 110,000 INR/day

Now, let’s sum up these expenses to calculate the total overhead cost per day:

Total Overhead Costs = Facility Maintenance + Security + Quality Control and Regulatory Compliance + Environmental Compliance + Administrative Expenses + Training and Development + Research and Development

Total Overhead Costs = 200,000 INR/day + 100,000 INR/day + 300,000 INR/day + 100,000 INR/day + 200,000 INR/day + 50,000 INR/day + 110,000 INR/day

Total Overhead Costs = 1,060,000 INR/day

Therefore, the total overhead cost component in hydrogen production through coal gasification is approximately 1,060,000 INR per day.

Hence, Cost overhead per kg hydrogen produced = INR 1,060,000/ 50000 = INR 21.2 per Kg

Per Kg Hydrogen Production Cost:

Total Per kg Hydrogen production cost = Direct cost (Fixed cost + Variable cost) + Indirect cost

= INR 34 + INR 84.56 + INR 21.20 = INR 139.76

Conclusion:

In conclusion, coal gasification offers a promising pathway for hydrogen production, presenting a versatile and potentially cleaner alternative to traditional coal combustion. Through a series of chemical and physical processes, coal is converted into synthesis gas (syngas), which primarily consists of carbon monoxide (CO) and hydrogen (H2), along with other gases such as carbon dioxide (CO2) and methane (CH4). This syngas can then be further processed to extract and purify hydrogen for various industrial applications.

One of the key advantages of coal gasification is its ability to utilize coal, a readily available and abundant resource, in a more environmentally sustainable manner compared to conventional coal combustion. By converting coal into syngas, coal gasification reduces the emissions of pollutants such as sulfur dioxide (SO2), nitrogen oxides (NOx), and particulate matter, leading to cleaner air and reduced environmental impact.

Furthermore, coal gasification enables the production of hydrogen, a versatile and clean energy carrier with numerous applications across various sectors. Hydrogen can be used as a feedstock for the production of ammonia, methanol, and other chemicals, as well as a fuel for transportation, power generation, and energy storage. Its combustion produces only water vapor as a byproduct, making it a promising solution for reducing greenhouse gas emissions and addressing climate change.

Additionally, coal gasification can enhance energy security by diversifying energy sources and reducing dependence on imported fuels. It provides a domestic source of hydrogen production, leveraging existing coal reserves and infrastructure to meet growing energy demand while reducing reliance on fossil fuel imports.

However, it’s important to acknowledge that coal gasification also presents challenges and considerations, including the management of byproducts such as carbon dioxide (CO2) and the environmental impact of coal mining and processing. Effective carbon capture, utilization, and storage (CCUS) technologies are needed to mitigate CO2 emissions from coal gasification plants and address climate concerns.

Furthermore, the economics of coal gasification and hydrogen production depend on various factors, including capital costs, operating costs, market demand, and government policies and incentives. Continued research, innovation, and collaboration are essential to further improve the efficiency, affordability, and environmental performance of coal gasification technologies.

In conclusion, coal gasification holds significant potential for hydrogen production, offering a pathway towards cleaner energy production, enhanced energy security, and sustainable economic development. With ongoing advancements in technology and supportive policy frameworks, coal gasification can play a valuable role in the transition towards a low-carbon energy future.
