Hydrogen can be extracted from fossil fuels and biomass, from water, or from a mix of both. Natural gas is currently the primary source of hydrogen production, accounting for around three quarters of the annual global dedicated hydrogen production of around 70 million tonnes. This accounts for about 6% of global natural gas use. Gas is followed by coal, due to its dominant role in China, and a small fraction is produced from from the use of oil and electricity.
The production cost of hydrogen from natural gas is influenced by a range of technical and economic factors, with gas prices and capital expenditures being the two most important.
Fuel costs are the largest cost component, accounting for between 45% and 75% of production costs. Low gas prices in the Middle East, Russia and North America give rise to some of the lowest hydrogen production costs. Gas importers like Japan, Korea, China and India have to contend with higher gas import prices, and that makes for higher hydrogen production costs.
Capital expenditure (CAPEX) is the other big cost component. CAPEX charges reflect the capital cost of building a new hydrogen production plant, and they depend on the type of technology used as well as the size of the plant. CAPEX costs can range from $403/m3 for small-scale steam reforming plants to $1000/m3 for larger, integrated facilities.
The electricity sector can also play a role in hydrogen production. This form of production uses electricity from renewables to produce hydrogen by electrolysis of water. Despite the fact that electrolysis has the lowest carbon dioxide emissions, it is also the most expensive form of producing hydrogen. High CAPEX costs and lack of access to renewable electricity at competitive prices means that this technology has yet to reach competitive levels.
Overall, the cost of producing hydrogen depends on the production method used, the availability of working capital, and the cost of the raw materials used. For example, when natural gas is used, the cost of production is largely determined by the price of the gas and the capital costs associated with constructing the plant. When electrolysis is used, the cost is largely determined by the cost of the electricity used.
For companies looking to reduce their carbon emissions, understanding the cost of producing hydrogen from different sources is essential. By factoring in all the economic and technical factors, businesses can develop the most cost-effective and sustainable means of generating hydrogen from various sources.
Dedicated electricity generation from renewables or nuclear power offers an alternative to the use of grid electricity for hydrogen production.
With declining costs for renewable electricity, in particular from solar PV and wind, interest is growing in electrolytic hydrogen and there have been several demonstration projects in recent years. Producing all of today’s dedicated hydrogen output from electricity would result in an electricity demand of 3 600 TWh, more than the total annual electricity generation of the European Union.
Despite the fact that dedicated electricity generation from renewables or nuclear power offers a viable alternative to grid electricity for hydrogen production, achieving cost parity with competing energy sources is still a challenge. This is due to the high capital intensity of the electrolysis process, which requires additional investments in storage and conversion technologies. Additionally, due to the large amount of electricity needed to produce hydrogen from electrolysis, the cost of electricity must be competitive.
To meet the targets set forth by the hydrogen economy, the technology must be able to produce hydrogen at a price that is competitive with its alternatives. This could be achieved through a combination of technological advances and policy support, such as dedicated subsidies or schemes like feed-in tariffs.
In addition to electricity costs, the cost of hydrogen production is also heavily dependent on the cost of raw materials used in the process, such as water and natural gas. Furthermore, with regard to natural gas, there is a progressive shift towards the adoption of clean energy sources, such as biogas, resulting in a growing share of renewable hydrogen in the production mix.
Overall, the cost of producing hydrogen is an ever-evolving landscape, with different technologies and sources competing on cost effectiveness. Companies must account for all economic and technical factors to ensure that they are using the most cost-effective and sustainable means of producing hydrogen. With the right combination of policy support and technological advances, it is possible to achieve cost parity with competing energy sources and unleash the potential of the
