Tomakomai CCUS Platform Project (Japan)

In Japan, the world's pioneering CCUS project is underway in Tomakomai, Hokkaido, involving the local community and many industries. The Port of Tomakomai is home to a major petroleum value chain and Japan‘s first CO2 capture and storage facility. Taking advantage of this feature, coupled with abundant renewable potential of Hokkaido, the project aims to realize a carbon-recycling business through cross-industry collaboration.

Carbon-recycling promoted in Tomakomai through cross-industry collaboration

Tomakomai is a leading industrial city in Hokkaido. It is home to not only the Yufutsu oil and gas field, the only commercially producing oil and gas field, and the only refinery in Hokkaido, but also many manufacturing plants for automobile, paper, chemical, and other industries. Most notably, this area has Japan's first large-scale CCS demonstration facilities. To put it another way, in Japan, it is practically the only location where the entire value chain from oil production, refining, and underground storage of CO2 is located.

Due to these characteristics of Tomakomai, Deloitte and Japan Petroleum Exploration Company (JAPEX) have begun a feasibility study of a carbon-recycling project through cross-industrial collaboration to achieve net-zero CO2 emissions for the entire city from 2021, under contract with New Energy and Industrial Technology Development Organization (NEDO).

Tomakomai's future vision to achieve with CCUS

Through dialogue with 38 local companies and organizations, Deloitte examined the situation of CO2, heat, and other emissions in Tomakomai and the combination of enterprises that could utilize these resources each other, drawing up a grand design (Figure 1) for the CCUS through cross-industry collaboration. First, CO2 pipelines will be used to connect large CO2 emitters with consumers, and exhaust gas from small CO2 emitters will be collected through the dedicated pipeline. To produce synthetic fuels, which is the primary consumer of CO2, the pipelines will also supply hydrogen, the raw material for the synthetic fuels. In addition, an electricity network will be established to supply locally generated renewable energy. The idea is to comprehensively lead the entire city to zero emissions through the three infrastructures: CO2, hydrogen, and renewable electricity infrastructures.

Having said that, it is not realistic to build all the infrastructure at once, since this plan involves large-scale infrastructure development, and some of the technologies under consideration are not commercially available at this time. Therefore, we developed a scenario in which technically established and economically feasible technologies, such as CO2-absorbing concrete, will be introduced initially and gradually expand deployments (Figure 2).

Deloitte's role in the Tomakomai project

The Tomakomai project is an idea that cannot be implemented by a single entity. It is designed to make effective use of resources, including CO2, through cross-industry collaboration. Coordination among a large number of enterprises is essential for the success of this project. Deloitte thus took on the role of a coordinator and drew a grand design for the project

In order to materialize the grand design, it is necessary to overcome complex challenges ranging from formulating regulations, building consortium to operation of CO2 pipeline. Deloitte is a consulting firm with a diverse range of professionals providing services from strategy consulting, financial advisory, auditing, and assurance. We will bring together these strengths to provide comprehensive support for the Tomakomai project all the way through to social implementation.
