Strategy

Priorities in Technology Development

In order to achieve its vision for the growth, development-focus, and conventional businesses in the Group Management Policies 2023, the IHI Group concentrates research budgets and human resources on the fields of these businesses to conduct technology development.
In fiscal 2024, the Group strengthened the structure of the Corporate Research and Development Division in order to accelerate the transition process from technology development into commercialization. Before the structural change, technology development to explore new technological and business fields had been collectively carried out by the Technology Platform Center, but the development functions toward new product launches were extracted and transferred to the newly-established Integrated Development Center. This organizational division will further promote fundamental technology development and provision of higher added value to products and services in collaboration with business divisions and affiliated companies, allowing technology development to move into commercialization quickly.

Growth Businesses

In the fields of aero engines and space, which are both the Group’s growth businesses, the Group is in the midst of developing technology related to the weight reduction and electrification of aircraft and equipment as well as sustainable aviation fuel (SAF) to make aircraft eco-friendly.

Development-focus Businesses

In the field of clean energy, which is the Group’s development-focus business, ammonia is positioned to be a sustainable fuel that does not emit CO₂ when combusted. In order to stimulate its demand and build a value chain for it, the Group is proceeding with the development of a 100% ammonia combustion gas turbine along with ammonia combustion technology for large-scale thermal power generation boilers.

Conventional Businesses

Within fields concerning resources, energy & environment, social infrastructure, and industrial systems & general-purpose machinery, which involve the Group’s conventional businesses, the Group promotes CO₂ emissions reduction and labor-saving technology as well as automation on the basis of lifecycle business.

Risks

Currently, international conditions and market environment are changing with astonishing speed, and existing businesses and technologies are likely to become obsolete within a short period of time. Under these circumstances, if the Group is unable to quickly provide services and products that solve social issues, there is potential risk of losing its competitiveness. This could have a significant effect on corporate value and financial condition. Moreover, if future predictions turn out to be incorrect, new ideas and developed technologies may not function as predicted in the market or cause unexpected issues.

Opportunities

The IHI Group possesses fundamental technologies, including rotating machinery, combustion, and welding, developed over many years as a specialist in both industrial and social infrastructure. In addition, through the development of new technology, products, services, and business models, it is possible for the Group to create new business chances in response to market changes and to maintain providing new value. Furthermore, the introduction of model-based development, a development method that utilizes simulation technology, can shorten development time and enable developed technologies to be put to practical use sooner, thereby leading to the creation of business opportunities. This gives the IHI Group a major opportunity to strengthen its competitiveness and ensure business sustainability, directly contributing to an increase in corporate value.

Initiatives

Achieving a Carbon-neutral World

Combined application of multiple technologies is essential for the IHI Group to contribute to achieving carbon neutrality by 2050. Consequently, the Group is simultaneously developing a variety of technologies, including fuel substitution into CO₂-free fuels and carbon recycling.
During the transition period toward carbon neutrality, it is also necessary to research and develop technologies for enhancing the efficiency of existing power generation plants and for reducing CO₂ emissions from them.

Utilization of Carbon-neutral Fuels

Efforts toward Making Use of Ammonia Fuel

The IHI Group has been developing technology for using ammonia not only as an inexpensive, safe hydrogen carrier but also as a carbon-neutral fuel with no CO₂ emissions during combustion.
In 2023, IHI signed a joint development agreement (JDA) with GE Vernova’s Gas Power Business. Going forward, combustion technology concepts will be evaluated for their ability to meet key operational requirements and the impact on the entire power plant.
In 2024, the Group implemented the world’s first demonstration testing of ammonia substitution at a commercial level, and achieved large-volume substitution of fuel ammonia (thermal capacity ratio: 20%). In addition, the Group is considering production of green ammonia derived from renewable energy with its overseas partners.
In order to promote the use of ammonia as fuel, the Group believes it necessary to build a value chain from production, transportation and storage to utilization, and for this purpose, established the IHI Corporation x Tohoku University Co-creation Research Center of Ammonia Value Chain for Carbon Neutrality together with Tohoku University. The Center is in the process of exploring issues and finding technological solutions for building this value chain.

Ammonia Production Using Renewable Energy

IHI has been developing a device to produce CO₂-free ammonia using hydrogen derived from renewable energy, and has confirmed that the device can produce ammonia at the target efficiency (ammonia production volume: 1 kg/day). IHI will continue more testing to verify the entire process, with the aim of scaling up the device and its commercialization.

Carbon Recycling

Capturing CO₂ and Converting It into Valuable Products

The IHI Group is developing technologies related to chemical absorption, which captures CO₂ from exhaust gas of business sites, and the direct air capture (DAC) technology, which captures CO₂ directly from the air. The IHI Group is also promoting the development of CCU^* technologies, with which the captured CO₂ is converted into valuable products, such as methane used as fuel, lower olefin used as a raw chemical material, and SAF.
The IHI Group’s methanation equipment uses an originally developed catalyst that boasts one of the longest service life spans in the world. Methanation is a key technology for carbon neutrality because it enables the utilization of existing city gas infrastructures.

Carbon dioxide capture, utilization

Sustainable Aviation Fuel (SAF)

The IHI Group continues to investigate and develop technology toward commercialization of SAF, which will help reduce CO₂ emissions from aero engines.
Regarding the development of SAF synthesis technology, the Group is conducting joint research with the Institute of Sustainability for Chemicals, Energy and Environment (ISCE²)^*. Based on the firsthand knowledge gathered during another ongoing joint development of lower olefin synthesis using CO₂ as a raw material, the research was conducted by efficiently exploring and adjusting test conditions such as catalyst composition and reaction conditions using machine learning, which is a type of AI. As a result, a catalyst with high performance in SAF synthesis was developed. This catalyst has achieved the world’s top-level performance as an SAF synthesis catalyst that causes H₂ and CO₂ to react directly, recording a 26% yield of liquid hydrocarbons with five or more carbon atoms (C5+ yield), which are raw material for SAF.
In fiscal 2024, to verify the entire liquid hydrocarbon synthesis process, the Group installed a small-scale production test rig on the ISCE² site that can produce 5 kg of liquid hydrocarbons per day. To ensure the feasibility of the entire process, the Group will continue to gather reactor data and optimize the synthesis plant’s operating conditions.

Open Innovation

The IHI Group regards collaboration with external partners important. Taking part in the global ecosystem communities, the Group encourages rapid and high-quality innovation through extensive collaboration with universities, research institutes, and customers.
In addition to the above-mentioned collaborations with Tohoku University and the ISCE², the Group implemented new joint research projects with Stanford University SUNCAT and Princeton University in fiscal 2024. Under these collaborations, the development of pioneering technologies is ongoing by taking advantage of the respective strengths.
With the goal of achieving early commercialization through collaboration with external parties, the Ignition Base (commonly known as i-Base), its base for open innovation, provides the Group with opportunities for deep discussions with its customers and helps it create new businesses.
In addition, the Group is seeking new technologies, joint research themes, and partners in Japan and overseas (in North America, Europe, and Asia).

Interfirm Collaboration in the Industrial Robotics Field

In order to accelerate the development of technology related to robot operating system (ROS), the IHI Group has been a participant in the ROS-Industrial Consortium since 2023. The Consortium is an open-source project bringing the advanced capabilities of ROS software to industrial-related hardware and application. The Group and the ROS-Industrial Consortium are in joint development of a fleet control system (maintaining a high level of efficiency in operation and control of multiple robots). The Group is making contributions toward accelerating the social implementation of robots by providing demonstration fields to the Consortium while acquiring knowledge about ROS industrial applications and system development.

Product Innovation

The World’s Largest Methanation Equipment

The IHI Group is developing methanation equipment, which is one of CCU equipment to manufacture fuel of e-methane (synthetic methane) through catalytic reaction between CO₂ emitted from plants and other facilities and hydrogen. Consideration is being given toward scaling up the conventional standard model (with a methane production of 12.5 Nm³/h) to a medium-sized model (500 Nm³/h) and even greater models. Taking a look at an example, the Group received a contract in 2022 that it would deliver a methanation unit for a carbon-recycling blast furnace^* in the East Japan Works Chiba District of JFE Steel Corporation in 2025. The unit is supposed to recycle 24 metric tons of CO₂ per day from exhaust gas and produce 500 Nm³ of methane per hour.
IHI’s methanation equipment currently holds one of the largest manufacturing capabilities in the world. The Group regards this contract as a good opportunity to work on materializing even greater equipment.

This carbon-recycling blast furnace is under construction in the course of developing low-carbon technologies using external hydrogen and CO₂ contained in blast furnace exhaust gas, based on the “Hydrogen Utilization in Iron and Steelmaking Processes Project, Japan’s Green Innovation Fund,” the New Energy and Industrial Technology Development Organization (NEDO)’s commissioned and subsidized research and development project JPNP21019.

100% Ammonia Gas Turbine Combustion System

In 2022, IHI successfully demonstrated the world’s first CO₂-free power generation using a 2 MW-class gas turbine fueled only by liquid ammonia^* and currently aims at putting this technology into practical use in 2026. In 2023, the Company signed a joint development agreement (JDA) with GE Vernova to develop a new gas turbine combustor that is capable to use ammonia for power generation and compatible with GE Vernova’s large-scale gas turbines. Combustion testing is being conducted at IHI’s facilities in Japan, and aiming to a potential commercially available product by 2030.

Ammonia Combustion Equipment

In 2024, IHI conducted the world’s first large-scale demonstration test (thermal capacity ratio: 20%) of ammonia fuel substitution for the large-scale commercial coal-fired power generator at the JERA Hekinan Thermal Power Plant (Hekinan City, Aichi Prefecture)^*. In this demonstration test, a 20% substitution of ammonia fuel was achieved, and it was confirmed that sulfur oxides (SOx) were decreased by about 20% and nitrogen oxides (NOx) were the same or less than before the substitution to ammonia fuel (combustion of conventional fuel only). Regarding N₂O, which has a strong greenhouse effect, no emission was confirmed (below the detection limit), and good results were obtained. It was also confirmed that operability was the same as before the substitution to ammonia fuel (combustion of conventional fuel only). Based on the results of the demonstration test, IHI is working to establish high-ratio combustion technologies fueled 50% or more by ammonia in thermal power plants and to develop a 100% ammonia-fueled combustion burner.
