Introduction

SatoClimate change is having an undeniably adverse impact on the human race and natural disasters such as heat waves, floods, typhoons, wildfires, and drought are becoming more frequent.
In response, the international community has established goals to achieve net zero emissions of greenhouse gases this century, such as the Paris Agreement signed in 2015 which advocates maintaining the average rise in global temperatures since the industrial revolution to less than 2°C, and ideally below 1.5°C. The Japanese government has declared its objective of becoming carbon neutral by 2050 as countries around the world increase their efforts to decarbonize. More than 8,000 private-sector companies, institutional investors, and higher education institutions are now engaged in private-sector initiatives under the United Nation’s ‘Race to Zero’ campaign, and an increasing number of financial institutions are calling for net zero initiatives at companies in which they invest as the decarbonization momentum increases.
Global temperature increase is an urgent issue and decarbonization must advance accordingly, while maintaining a reliable supply of energy to support social and economic activities. This will be challenging and we should discuss how Chiyoda Group can support this objective and its decarbonization and recycling vision for the future, while ensuring a reliable energy supply.
Decarbonization while Ensuring a Reliable Energy Supply with LNG

TanakaIt is important to optimize decarbonization and energy supply solutions from short, medium, and long-term
perspectives. While decarbonizing energy is the ultimate goal, renewable energy alone is unlikely to meet demand. Renewable energy including hydrogen, ammonia, and other forms of clean energy will take time and involve substantial sums of money to develop and implement technologies in society and upgrade infrastructure. In the short and medium term, a realistic approach will be to ensure a reliable supply using traditional energy sources and, from a long-term standpoint, reduce, capture, and store CO2 emitted from them while transitioning to renewable and clean energy.
As a Chiyoda Group core business, LNG is an essential source of energy as we progress towards decarbonization because it is reliable and has relatively low environmental impact. I am currently involved with the Qatar LNG project that reduces CO2 emissions through carbon capture, utilization, and storage technology and will support a stable energy supply when complete.
The movement towards decarbonization is also pivotal to our Company’s sustainability and I will create conditions whereby all Chiyoda Group colleagues can explore new technologies, as we tackle global challenges and successfully complete projects that generate profit.
Supporting the Transition to Renewable Energy with Offshore Wind Power

TangeThere were relatively few renewable energy projects when I joined Chiyoda Group in 2009 but, in line with the shift
towards decarbonization over the past 10 years, we have aggressively developed new business in the renewable energy, power generation, and storage fields, including solar power generation, solar thermal generation, biomass power generation, storage systems, and offshore wind power generation.
Offshore wind power generation is expected to play a major role in the transition to renewable energy as a core power source, and national and international companies are planning to develop this market around Japan.
However, projects can take a decade from commercial evaluation to completion and operation and a long-term view is required to increase the weighting of renewable energy in the energy mix.
Although offshore wind power generation is still a relatively small market in Japan, Chiyoda Group receives orders from power generation companies to conduct feasibility studies, basic engineering work and compile budget estimates. Offshore wind power requires both civil engineering and electricity generating proficiency and, although these may not be Chiyoda Group’s main areas of expertise, I believe we can transfer strengths from our core disciplines into these fields.
As we incorporate advanced technologies from Europe, it will be essential to adapt these technologies to the environmental conditions and regulations unique to Japan and Chiyoda Group is in a good position to partner with European firms and other foreign companies to bring European technologies
here. These projects are huge and require advanced engineering and construction technologies. Chiyoda Group’s project management capabilities, accumulated over many years in the petroleum, petrochemical, and gas fields, will be invaluable for their successful completion.
In conversations with clients, I can sense their expectations of Chiyoda Group as an engineering company and I will leverage our strengths as we contribute to offshore wind power generation in Japan.
Delivering Optimal Decarbonization Solutions to Clients from a Multifaceted Approach

SekiguchiIn the Project GX Strategy & Development Department, we are developing strategies for new overseas
projects and to establish decarbonization as a new business pillar. Because the different decarbonization methods have their own unique advantages and disadvantages and implementing them raises different challenges, a solid understanding of the features of each method is required to evaluate each one while, considering their applicability to the industries and companies using them. Understanding unique national and regional traits when considering overseas projects is fundamental. For example, we envision the expansion of CCS* and the introduction of hydrogen and ammonia in countries that use LNG as a primary fuel, whereas switching to LNG is the next step towards decarbonization in countries that use a large proportion of coal. Different countries and regions have dissimilar levels of natural energy resources, such as solar and wind power, and varying policies and priorities for decarbonization is necessary to select the most ideal solution, with an understanding of the unique challenges faced by native companies and people.
Our technological capabilities are also key for delivering optimal solutions to the client and we are currently evaluating the company’s CCS technologies, of which there are many. I wish to create new businesses, while contributing to the decarbonization of society, by delivering optimal solutions to our clients and redefining the value of the Company’s diverse decarbonization technologies.
- * Carbon Capture and Storage
SatoEveryone’s experience in the energy field and your aspirations for decarbonization reinforces the increasing
momentum towards energy transition.
Energy producing equipment is durable and can last for decades. It is therefore essential to rapidly commercialize
technologies for reducing, capturing, and reusing CO2 emissions for installation into existing facilities. I also look forward to observing steady progress towards renewable sources of energy, such as offshore wind power. As an engineering company, Chiyoda Group must utilize its technological capabilities even more effectively, and leverage existing technologies while accepting new challenges.
Supporting Client Decarbonization with our Technological Capabilities and Ability to Implement Technologies in Society

KawaiThere are four key technology issues for capturing and reusing CO2, producing hydrogen and manufacturing carbon neutral products as we progress towards decarbonization and carbon recycling. First is efficiently capturing CO2 from low-density gases that contain impurities; second is stabilizing the fluctuating supply of green hydrogen for delivery to downstream facilities; third is efficiently separating byproducts containing product material for downstream delivery; and fourth is efficient low-cost production while optimizing the overall system. However, these issues are not insurmountable. Chiyoda Group’s strengths derive from: (1) its technological capabilities from combining existing and new technologies based on comprehensive and fair evaluation, while compensating for variances in the physical nature of materials, and (2) its project execution capabilities, derived from business plans, to efficiently manufacture products.
Chiyoda Group contributes by developing proprietary technologies and through new technologies jointly developed with national and international partners. This includes the integration of digital technologies into process technologies, such as next-generation fuel production and chemical
products such as paraxylene and ethylene produced from CO2 and green hydrogen. This also encompasses virtual power plants, optimizing electrical power and heat including solid absorbents that efficiently absorb low-density CO2, and SPERA Hydrogen, Chiyoda Group’s proprietary hydrogen technology.
In addition to the optimal deployment of existing and new technologies, Chiyoda Group can leverage its experience of executing projects during all stages of their life cycle, from feasibility studies to operation and maintenance, to support clients achieve their decarbonization and carbon recycling objectives.
Optimizing the Energy Value Chain with Digital Technologies

FuruichiAs Mr Kawai discussed, and in my experience of using digital technologies to support facility operations, I
think Chiyoda Group is able to accomplish so much because it can combine digital technology capabilities with engineering.
There are many stakeholders in the wide variety of clean energy sources as the world transitions to a decarbonized society and, as the energy value chain becomes more complex, there will be a larger interconnected impact. The ripples from an unplanned event affect the entire value chain, and effective risk management is essential to comprehensively assess and mitigate risks that may influence schedules and costs. Such a process can only be possible by applying lessons learned from many years of EPC project experience. I hope to facilitate the use of digital technology on energy projects to enhance the Company’s project engineering and execution management capabilities. We are aiming to optimize our operations while ensuring resilience by monitoring risks and opportunities throughout the entire energy value chain and applicable systems. The expected role of digital technology includes the collection and visualization of real-time data that facilitates adjustments and decisions which, when combined with experience, enables the creation of indicators and future projections to manage overall operations to the satisfaction of all parties.
Chiyoda Group will continue supporting client business transformation through client new technologies as their industry evolves through decarbonization and carbon recycling, and we will continue developing close and enduring working relationships with our clients as we resolve issues as ‘One
Team’. I aim to create systems and develop a corporate culture that continues to train teams and human resources to identify core issues and their resolution. Working together as ‘One Team’, we will continue to progress as an engineering company, focusing on AI and digital technologies.
Reducing CO2 Emissions in Procurement by Improving Transportation Efficiency

GotoI am responsible for the transportation of procured goods in the Procurement Department and my approach to
decarbonization is slightly different. While ensuring safety and quality, procured equipment and materials must be delivered to worksites when required to avoid schedule impacts, and increasing the transportation efficiency of procured equipment and materials also reduces CO2 emissions.
For example, increasing the load ratio by more efficiently loading products into containers to maximize a ship’s cargo, reduces the number of trips from the loading site to the ship and minimizes their CO2 emissions. I ensure that all project personnel consider the size of equipment and materials at the engineering stage, including packaging specifications, to increase transportation efficiency.
Using digital technology to ensure that all the parties involved in the efficient procurement and transportation of materials and equipment receive real-time information, improves the efficiency and quality of transportation.
Today’s discussion was an opportunity to reflect on sustainability initiatives in transportation. Our attention is naturally drawn to impending and immediate delivery schedules and costs, but I intend to use the Company’s transportation expertise and experience to initiate improvements in sustainability.
SatoI now have a greater understanding of the significant potential of an engineering company like Chiyoda Group,
given the many new technologies, such as hydrogen, next-generation energy, virtual power plants, and AI. Decarbonization should be incorporated into the entire supply chain, and advancing it at the procurement stage makes a substantial contribution.
Chiyoda Group has earned the trust of large international clients though its technological capabilities, track record over many years client and successful execution of projects using superior management capabilities. While responding to changes in the business environment, Chiyoda Group should maintain these competitive strengths and, by exploiting synergies, the Company will be able to deliver innovative solutions to clients and add value to society. Developing new businesses on the path to decarbonization comes with uncertainties in terms of technologies, markets, and regulatory restrictions. I look forward to working with everyone in exploring opportunities for the Chiyoda Group Group to grow and achieve future goals, while contributing to decarbonization in society.
