Case study for the second stage: Reflections on the preliminary decision-making for Shenhua Dow Yulin Coal Chemical Project. Dear netizens: Hello everyone! In the previous issue, we discussed the “double-high” decision for the PPS project, which is a case where both scientific and commercial evaluations were successful. Today let’s discuss another case—a project that provided valuable lessons during the initial planning stage. I did not experience this case personally; it is rather a well-known project in the chemical industry: the Shenhua Dow Yulin Circular Economy Coal Comprehensive Utilization Project. High hopes were placed in it, but it ended with the partner withdrawing and the project being shelved. I wasn’t at the scene, so many details cannot be confirmed, but based on public reports, its experiences during the initial planning stage offer some insights that are worth considering when understanding several key issues in the phase of innovation development. I. Project Background Around 2005, Shenhua Group and Dow Chemical began planning to build a super-large-scale coal chemical project in Yulin, Shaanxi. The plan was to use coal as raw material and, through processes such as coal gasification, methanol synthesis, and methanol-to-olefins conversion, produce various chemical products including olefin derivatives. The scale of this project was extremely astonishing at that time: the initial planned investment amounted to as much as 150 billion yuan, but after several adjustments it was reduced to around 126 billion yuan. If completed, it would have been the largest single coal chemical project in the world at that time. From the initiation of planning in 2005, to the signing of a framework agreement between the two parties in 2007, and then to the laying of the foundation for the project in 2009, it took nearly a decade to conduct evaluations, reviews, and make adjustments to the plans for this project. But in 2014, news reached the market: Dow Chemical had explicitly withdrawn from the project. Although Shenhua stated at the time that the project had not been halted, by 2015 the company faced financial difficulties, and this project worth hundreds of billions was effectively postponed indefinitely. Why has a project that has been under development for a decade and has required substantial upfront investment reached this point? Where is the problem? II. What were the problems in the preliminary feasibility study phase? According to public reports, there were several notable issues with this project during its preliminary feasibility study stage. First, scientific validation has been in progress for a decade, but the market environment has undergone fundamental changes. The preliminary feasibility studies for the Shenhua Dow project were carried out with great care. It is reported that this project had its process plan revised nine times over a decade, with the target number of products decreasing from over 70 initially to just over 30. The approval procedures for environmental impact assessments, water resource evaluations, feasibility study reports, etc., have also been completed. From a technical perspective, this project underwent extremely thorough scientific validation. The core technologies of coal chemical processing—coal gasification, methanol synthesis, and MTO—already had multiple industrial plants in operation at that time, so there was no lack of technical precedents. But the problem is: the market environment has changed. During the project feasibility study period, international oil prices continued to decline, prices of chemical products weakened, and the cost advantage of coal chemical industry gradually diminished. It is reported that in 2014, “the prospects for the chemical industry were not as optimistic as they had been at first, and the market was relatively weak.” After the financial crisis in 2008, Dow Chemical’s performance declined significantly, with its net profit dropping by nearly 80%, forcing the company to take measures such as laying off employees and closing factories. Shenhua has also been affected by the sharp decline in coal prices since the second half of 2011. A project was evaluated for ten years, during which the market environment, the operating conditions of partners, and industry cycles all underwent significant changes. The assumptions made during the business case preparation – high oil prices, high prices for chemical products, and healthy financial conditions of the partners – were no longer valid when it was time to actually move forward with the project. Second, as the scale of investment continues to expand, there is a significant discrepancy between economic cost calculations and actual conditions. It is reported that the Shenhua Dow project was initially expected to cost around $10 billion, but the investment amount later increased to over 120 billion yuan. Analysts point out: “The coal situation is poor, and Shenhua doesn’t have that much capital of its own.” ” The scale of investment is one of the most critical variables in the economic evaluation of a project. As the investment budget expanded from the initial 10 billion dollars to higher figures, the project’s payback period and internal rate of return changed significantly. But the problem isn’t the expansion of investment scale itself—increased investment in large-scale projects is a common phenomenon during the planning phase. The question is: when signs of an expanding investment scale appear, did the project’s decision-makers promptly reevaluate its economic viability, and did they stop at a critical point to reconsider whether the project was still worth pursuing? Third, the environmental sensitivity and policy risks of coal chemical projects were not adequately anticipated. The Shenhua Dow project went through an environmental impact assessment approval process that lasted nearly a decade. The project is located in the desert area of northern Shaanxi, where the ecological environment is fragile and the progress of the environmental impact assessment is slow. It is reported that the total environmental protection investment for these two main projects amounts to 7.175 billion yuan; “over the past decade, efforts have mainly focused on environmental impact assessment, design adjustments, and the optimization of product lines.” Over the course of a decade, the process design was changed nine times, largely as a response to the evolving environmental constraints. The trend of tightening environmental policies can be anticipated at the outset of a project. The water consumption, carbon emissions, and waste discharge associated with coal deep-processing projects are naturally subject to increasingly stringent environmental protection regulations. But in the initial market feasibility study, were these environmental compliance costs properly anticipated and taken into account in the economic model? When the environmental impact assessments were gradually carried out over a decade, did anyone systematically evaluate how much the continuous tightening of policies would affect the economic viability of the projects? Answers to these questions cannot be found in public reports—but what happened later showed that the project ultimately failed to start on a full scale, with the lengthy environmental impact assessment being one of the key reasons for this. Fourth, under resource constraints, project managers may have biased assessments of economic prospects. This isn’t to say that the managers at Shenhua or Dow are unprofessional. On the contrary, both parties are leading enterprises in their respective fields. But it is precisely because of the project’s enormous scale, the high expectations placed on it by all parties involved, and the substantial initial investments required—that reportedly, the project covers an area of 18,000 mu (about 13 square kilometers), with the designed recoverable reserves of the coal mines amounting to 1.287 billion tons, and the investment in just the coal mines exceeding 4.2 billion yuan—that such large figures themselves can create a psychological tendency to think that \"this project is too big and too important to be halted.\" When adverse changes occurred in both the business performance of partner Dow Chemical and the market environment, the feasibility study continued. The environmental impact assessment remained pending approval. The project kept cycling through a process of “studying, modifying, and re-studying,” with no one making the decision to say, “It’s time to stop now.” III. Root cause analysis: The cumulative problems in circular reasoning. From the perspective of the seven-stage model, there are several aspects of the Shenhua Dow project’s innovation incubation phase that merit reflection. A lot of scientific reasoning was done, but it wasn’t enough to guide critical business decisions. The project took ten years to justify, with the plan changing nine times, reflecting thorough deliberation. However, the argument takes too long, and the market assumptions set at the beginning of the argument are no longer valid by the end of it. The market environment has changed, but the reasoning still relies on old assumptions. The assumptions of a business case need to be updated dynamically. The business case during the innovation incubation phase is not something that can be completed once and then set aside. When significant changes occur in the external environment—oil prices, market supply and demand, the operational conditions of partners—it becomes necessary to reevaluate the original business case. Market validation cannot “serve for a decade at a time”; it needs to be calibrated regularly. The scale of investment expanded rapidly, but a Go/No-Go decision was not made in a timely manner. The investment scale underwent a significant change from the initial projections to the final actual budget, yet the project continues to move forward. This is one of the most common problems in the innovation incubation phase – failing to say No when it’s necessary, and continuing forward driven by sunk costs. The long-term costs of environmental constraints may be underestimated. The Shenhua Dow project spent a significant amount of time in the early stages on environmental impact assessments, which shows that environmental factors are indeed key determinants of the project’s feasibility. But if environmental constraints could be assessed more carefully during the innovation development stage – not just to determine whether an environmental impact assessment can be approved, but also to consider whether compliance costs will continue to rise, whether the construction period will be extended, and whether stricter policies will alter the economic viability of the project – decisions might be made more cautiously. IV. If I could do it again, these are some of my thoughts after reviewing this case on my own. First, the business case should be regularly calibrated. It is not sealed off after just one completion, but rather re-evaluated every six months or a year, whenever there are significant changes in the external environment. This mechanism is even more important, especially for large projects whose approval process can be very long. With such a mechanism in place, when oil prices fall and the performance of partners deteriorates, the decision-makers can promptly receive signals that the conclusions of the business case are changing. Second, once there is a significant deviation from the investment budget, it should trigger a thorough re-evaluation. It’s not that investment must be halted just because it has increased; rather, questions such as “why is it increasing” and “is it still economically viable after the increase” need to be seriously discussed at the decision-making level. But in practice, once many projects enter the lengthy process of \"evaluation and approval,\" a certain inertia develops – all resources are directed toward moving forward, with few asking whether it is still necessary to proceed at this point. Third, the impact of environmental constraints on the economic viability of projects deserves to be included in risk analysis. Large-scale chemical projects are inherently deeply affected by environmental policies. During the innovation incubation phase, policy risk assessment is not merely about whether an environmental impact assessment can be approved; it also involves considering more long-term issues: will environmental protection costs continue to rise? Will policies be tightened further? If the worst-case scenario occurs, can the project still be established? V. Final Thoughts: The Shenhua Dow project, just like the phenylacetic acid project I was involved in, has made me deeply understand the importance of not skipping any steps during the innovation development phase. The difference is that the issue with the phenylacetic acid project lies in insufficient depth of analysis and incomplete risk identification ； The problems with the Shenhua Dow project stem from rapid changes in the market environment, expanding investment scales, and tightening environmental regulations. What they have in common is that they all sowed the seeds of future failure at the stage of innovation incubation. One reason is that the necessary analyses were not conducted thoroughly, and the other is that the reasoning process took too long; the assumptions made at the beginning are no longer valid in the new market conditions, yet work continues based on those old assumptions. This also confirms an important principle in the innovation incubation phase: business case development is not a one-time task. It requires dynamic calibration. When the market changes, the conclusions of the arguments may change as well. Just because the argument has been made does not mean it no longer needs to be examined. Preview for the next issue: Issue 18 – Conclusion and reflection on the innovation incubation phase. By reviewing PPS’s successful achievement of the “double high” standards as well as the lessons learned from the Shenhua Dow case, what can we draw from these two examples—one positive and one negative? What are the most core principles in the innovation incubation phase? The next issue will cover the final stages of phase two.
