Clean Tech Business

Policies and Basic Approach

We have identified climate change as one of the key themes of sustainability management in our Medium-term Management Plan 2023. We have also stipulated in our Environmental Policy that we will strive to develop and promote technologies and new businesses that reduce environmental impact. As the Mitsui & Co. group, we are actively working to resolve social issues through a wide range of global business activities. Moreover, we announced our goal to achieve net-zero emissions as our Vision for 2050, aiming to halve our GHG impact by 2030 compared to 2020 levels. To achieve this goal, we are positioning technological innovation in the environment and clean tech fields as a core strategic field, and we have stipulated in our Environmental Policy that we will strive to develop and promote technologies and new businesses that reduce environmental impact. In April 2020, we set up our Energy Solutions Business Unit to speed up the progress of complex and adaptive initiatives, and are working to promote existing initiatives, formulate new projects, and pursue and expand investment opportunities in this field.

Goals and Targets

  • Increasing the percentage of renewable energy (including hydropower) in Mitsui's equity-based electricity generation capacity to 30% by 2030.
  • Contributing to technological innovation and reduction of environmental impact by accelerating and expanding our business and R&D activities in the clean tech field, including businesses related to alternative fuels such as hydrogen, ammonia, and next-generation ethanol, EV-related and battery-related businesses, energy management businesses, low-carbon production in the steel industry, recycling businesses, and CCS and CCU businesses.

Introduction of Internal Carbon Pricing System

At Mitsui, we introduced the internal carbon pricing system in April 2020 in order to increase the medium to long-term resilience of businesses emitting large volumes of GHG, and to encourage the development of projects that are effective at reducing GHG emissions. Regarding new business projects, in projects with potential risks or opportunities from GHG regulations, etc., we have added analysis of the potential impact of a 2°C scenario to the project screening factors, as well as the reasonableness of countermeasures in the event these risks are realized. We are also using the internal carbon pricing system to assess risks in existing projects.

Environmental ("Green") Business Assessment Working Group

We have set a goal of net-zero emissions in our vision for 2050, and we aim to halve our GHG impact compared with 2020 levels by 2030. To achieve these goals, we will need not only to take action on projects that emit large amounts of GHGs, but also to increase our efforts to create projects that will help to reduce GHG emissions while improving profits. For these reasons, we have decided to establish the Environmental ("Green") Business Assessment Working Group. Its role will be to carry out comprehensive evaluations as part of the screening of new projects with the potential to turn climate change responses, such as the development of renewable energy, into opportunities. The evaluations will include qualitative factors, such as the strategic significance of initiatives from ESG perspectives.

Hydrogen Station Business in California

  • Energy Solutions Business Unit
  • Performance Materials Business Unit

California is an area that is famous for pioneering environmental initiatives and as of 2020, there were over 9,000 fuel cell vehicles ("FCEV") being used in the state, around twice as many as in Japan. Mitsui was quick to take notice of this, and we have launched a business collaboration with FirstElement Fuel, Inc. ("FEF"), the largest hydrogen station developer and operator in California. FEF currently operates 23 hydrogen stations and it will continue this development into the future in order to facilitate the further spread of FCEV. Following on from passenger vehicles, from 2024, operators of commercial vehicles such as buses and trucks in California will be required to transition to zero-emission vehicles, so we plan to build a hydrogen refueling framework, including hydrogen stations, to ensure that important commercial vehicles can continue to operate over sufficient distances and with appropriate cargo capacities. As another example of our FCEV-related business, in 2016 we invested in Norway's Hexagon Composites ASA, the world leading manufacturer of lightweight pressure cylinders, and we are working with the company to develop trailers for transporting hydrogen using pressure cylinders. Together with FEF, we will use these trailers to launch a framework for lower-cost distribution of hydrogen to hydrogen stations.

Hydrogen Supply Chain Business

  • Energy Solutions Business Unit

We are involved with the Advanced Hydrogen Energy Chain Association for Technology Development (AHEAD). In 2020, we conducted the world's first large-scale hydrogen transportation demonstration project in which hydrogen was transported from Brunei to Japan (Kawasaki City) in the form of methylcyclohexane (MCH) and used to co-fire a gas power generation facility. This approach to transporting hydrogen using MCH is known as the organic chemical hydride (OCH) method. It converts hydrogen into a substance that is a liquid at normal temperature and pressure that is easy to handle and can be safely stored and transported. Another advantage of MCH is that it can be stored using existing petroleum infrastructure. This demonstration project has set the stage for the construction of a hydrogen supply chain which is a new form of energy supply.

Battery Systems for Mobility Applications

  • Energy Solutions Business Unit

Against a backdrop of growing environmental awareness and the need for air pollution control measures, the electrification of mobility has begun in earnest, mainly in Europe and China. Electrification will cover a wide range of fields in the future, from passenger cars to route buses, scooters, ships, and industrial machinery. We expect that electrification will progress in a wide range of fields in the future. Our affiliated company Forsee Power SAS is working to build an ecosystem that takes batteries previously used for mobility and reuses them as stationary storage batteries. In addition to manufacturing and selling battery systems essential for the electrification of mobility, Forsee provides battery leasing services (Battery as a Service) with a view to future battery reuse and recycling.

Electricity Resource Development and Power Management

The Smart Grid and Distributed Electricity Resources

  • Infrastructure Projects Business Unit

Demand for energy has been growing throughout the world, especially in Asia and Africa, along with the steady economic growth of these regions. The power sector has seen a pronounced trend towards Decarbonization, Decentralization, and Digitalization (the "3 D's"), and a rapid shift is underway towards renewable energy, which is more environment-friendly. Mitsui & Co. is responding to the "3 D's" trend not only through the development of utility scale solar power and wind power projects, but also through the global roll-out of distributed power generation projects that provide service closer to the end-user. Globally, approximately one billion people—mostly in Asia and Africa—have limited access to electricity*, and for India also, this is a major problem. At the same time, mobile phone penetration rates tend to be very high even in the inadequately-electrified regions of India and Africa, making electricity necessary for communication purposes. In 2017, we invested in OMC Power Private Limited (OMC), which is specialized in a business model with a combination of solar power and batteries to implement a distributed electricity generation business in which electricity is produced and consumed locally. With mobile carriers' telecom towers being the anchor customers, OMC supplies reliable electricity to local businesses and communities as well. OMC provides stable and affordable electricity mainly through environment-friendly solar power, as well as enhancing the lives and economic prosperity of rural communities. Currently, OMC operates 196 power generation plants, which supply power to 209 telecom towers, 5,000 local businesses, and approximately 100,000 residents in 15,000 households. We will be working with OMC to deliver electricity to other inadequately-electrified regions.
We also help to supply electricity to sub-Saharan Africa through our investment and participation in M-KOPA Holdings Ltd. ("M-KOPA"). M-KOPA runs a business called the Solar Home System ("SHS"), through which solar panels are installed on the roofs of houses or small stores, and solar power generation is used to provide power for lighting, mobile phone chargers, and home appliances (radios and televisions). Up until recently, more than 600 million people living in sub-Saharan Africa have been using kerosene, which is a fossil fuel, for lighting and cooking, because of the delayed development of the power transmission grid. However, thanks to the SHS, there has been a reduction in kerosene use, helping to reduce the environmental load. In Africa, a large increase in demand for electricity is expected as a result of the improved living standards and lifestyle changes that will result from future rapid economic growth. By accelerating efforts to strengthen and expand the services M-KOPA provides, we will support more convenient and comfortable lives for people living in Africa.

An Energy Management Business that uses Battery-powered ICT Systems

  • Energy Solutions Business Unit

While the amount of new renewable energy is increasing globally, issues such as growing loads on transmission and distribution systems, an imbalance in the burden of electricity charges, and complicated supply and demand coordination are becoming issues. In response to these issues, we have invested in Stem and Sunverge, two companies that offer energy management services that employ energy storage ICT systems. We are also working on the development of new business models to meet diversifying needs -- for example, providing solutions that package Stem's energy storage system and Forefront Power's distributed solar power. Forefront Power is a wholly-owned subsidiary engaged in the distributed solar business for industrial and commercial consumers and public institutions in North America. Another issue is the increasing volatility in the electricity market due to the rapid spread of renewable energy. We are responding to new needs due to structural changes by providing solutions such as price hedging and supply and demand adjustment functions. In Europe, through such initiatives as our investment in Evora Energy Limited of Ireland, we are doing our part to help business expansion and functional improvement in the electric power logistics sector.

Natural Gas Electricity Generation

  • Energy Business Unit II
  • Infrastructure Projects Business Unit

Fukushima Gas Power Co., Ltd., a company in which we have a 29% stake, has two natural gas-fired power generation facilities at its Fukushima Natural Gas Power Plant at Soma, Fukushima Prefecture. These have a total power output of 1.18 million kW. The power generation facilities use a gas turbine combined-cycle system with high power generation efficiency. This combination of a gas turbine and a steam turbine generates a lower level of CO2 than conventional thermal power generation methods.
This project is in line with Fukushima Prefecture's goals of the "introduction of energy with a low environmental impact" and "new urban development". Through the promotion of this project, Mitsui & Co. will contribute to the economic revitalization in the Hama-dori region of Fukushima prefecture to help in its ongoing recovery from the 2011 earthquake. We will continue to work on the sustainable and stable supply of resources that are essential for social development and the creation of a society that is in harmony with the environment.

EV (Electric Vehicles)

  • Mobility Business Unit I
  • Energy Solutions Business Unit

Among the mobility (transportation) fields that we have defined as our new growth fields, we expect electrification (the shift to electric vehicles) to be particularly promising. In Europe, where the introduction of EVs is gathering momentum, we are building a comprehensive business model that supports the changeover to EVs, including infrastructure, and are expanding it in other regions as well.
We are organically linking several companies in which we have an interest. These include EV makers (Lucid Group, CaetanoBus-Fabricação De Carroçarias S.A、Letenda Inc.), battery pack manufacturers (Forsee Power SAS), and an energy management company that uses EV batteries (The Mobility House). We aim to build a new business model that can provide comprehensive solutions. For example, if a city considers switching its fixed-route buses to EV, we would like to help the city speed up its changeover to electric vehicles. In concrete terms, we can offer a comprehensive range of services including EV bus supply, battery leasing, and energy management. Furthermore, in future we are also considering businesses involved in the reuse and re-leasing of used batteries. We will begin these initiatives in Europe and the United States, and then expand them to Asia.

ZEV (Zero Emission Vehicle) Bus Operations in Europe

  • Mobility Business Unit I

In December 2017 we invested in Caetano Bus, S.A. of Portugal. This company has been involved in the development of electric buses since 2010. In 2016 they began the sale of ramp buses used to transport passengers within airports, and in 2017 the company started commercial production and sales of electric transit buses in Europe. We are using our global network to help in the expansion of sales of the company’s buses. As an example of Caetano's global expansion, a total of 34 single-deck electric buses were delivered to two London routes in the spring of 2020. The company also completed the development of an FC (fuel cell-powered) transit bus at the end of 2020. Beginning with Germany and Saudi Arabia, we have started selling FC buses that use Toyota fuel cell systems. In our partnership with Caetano Bus, we will continue looking to provide the optimal solutions suitable for operations seeking to achieve a carbon-free society.

Participation in the CCS Business

  • Energy Business Unit I

CCS stands for Carbon Capture and Storage. We have invested in CCS company Storegga Geotechnologies Limited ("SG") of the UK. SG, through its wholly owned subsidiary Pale Blue Dot Energy Limited, is developing the Acorn CCS project to capture, transport, and store CO2 emitted from the UK and neighboring countries, to reduce CO2 emissions and achieve CO2 Net-zero emissions by 2050, a target that has been set by the UK government. The Acorn CCS project will use depleted oil and gas fields where production has ceased as reservoirs for the storage of CO2. In this way, the project will reutilize existing infrastructure and will achieve cost competitiveness. SG is also working to commercialize its Direct Air Capture technology to extract CO2 directly from the atmosphere. We will use our knowledge of upstream oil and gas businesses and our extensive business network to help SG strengthen its business base through management participation and business alliances. Utilizing our comprehensive abilities together with the knowledge gained in the UK and Europe where development of governmental rules and regulations of Carbon Capture, Utilization, and Storage ("CCUS") businesses is advanced, we aim to develop a global CCUS business that will include Asia and will provide CO2 reduction solutions to the world.

CCU — Producing Methanol in the U.S. that Effectively Uses CO2

  • Basic Materials Business Unit

Our affiliate, Fairway Methanol LLC, decided in March 2021 to expand its facilities to increase methanol production (approximately 130,000 tons per year) by purchasing and effectively utilizing by-product carbon dioxide (CO2) from surrounding plants (up to approximately 180,000 tons per year) as the source. The decision to expand its facilities was made to maximize the effective capacity of the existing plant, and carbon dioxide sourced from neighboring plants will be used as the raw material for the plant's newly added capacity. This is a CCU (Carbon Capture and Utilization) initiative, which involves separating and effectively utilizing carbon dioxide. Under this concept, CO2 is considered a resource that can be reused as a material or fuel, thus realizing carbon recycling to reduce emissions into the atmosphere.
Demand for methanol is expected to grow steadily in the future as a basic raw material for a variety of industries, including housing and construction materials, high-performance resins for automobiles and electronics, and pharmaceuticals. Recently, methanol has also been attracting attention as a key chemical substance that can be sourced from carbon dioxide. Mitsui has been engaged in the methanol trading business for many years. In addition to the business in North America where this expansion will take place, Mitsui is also involved in a methanol production business in Saudi Arabia.
Through the stable supply of methanol, Mitsui is supporting the development of a wide range of industries and contributing to the realization of a sustainable society. Furthermore, to achieve Net-Zero Emissions by 2050, which is the target set in our Medium-term Management Plan, we will make use of our existing businesses and the know-how we have accumulated through them to promote initiatives to realize a decarbonized society.
