[Seminar] Latest Status of Next-Generation Energy Technologies Pursued by NTT

[Speaker] EY Strategy and Consulting Co., Ltd. Transaction and Corporate Finance M&A Advisory Director Naoki Saito [Key Lecture Content] In recent years, the grid-scale battery business has garnered significant attention from practitioners, particularly in the renewable energy sector. However, it is also true that there are several challenges that remain to be addressed for further investment expansion. In this lecture, we will explain the finance environment, various markets utilized for revenue generation, and the diversifying business schemes that could influence the success or failure of investment expansion. We will also introduce the current challenges related to each theme, the efforts of market participants towards their resolution or improvement, and future outlooks. [Lecture Items] 1. Overview of the business surrounding grid-scale batteries (historical trends, etc.) 2. Diversifying business schemes 3. Current challenges hindering further investment expansion (finance methods, etc.) 4. Various initiatives towards problem-solving 5. Q&A / Business card exchange

[Speaker] Hiroaki Izuma, Advisor, Business Creation Division, Tohoku Electric Power Co., Inc. Director, Osaka University Foresight Co., Ltd. [Key Lecture Content] Renewable energy (solar power, wind power) is unstable, so Short-term Energy Storage (SDES) is necessary. The main SDES is lithium-ion batteries, which can store energy for several hours, but as the ratio of renewable energy is expected to reach about 50% in the future, Long-term Energy Storage (LDES) will be required. LDES can store energy from 10 hours to several months. The technological classifications of LDES include electrochemical, mechanical, thermal, and chemical methods. In this lecture, we will explain the characteristics of each LDES method, promising overseas startups, and the progress of social implementation, providing insights into new business opportunities. [Lecture Items] 1. Background for the need for LDES 2. Characteristics of the four technological methods 3. Promising overseas LDES startups and social implementation (1) Electrochemical method (2) Mechanical method (3) Thermal method (4) Chemical method 4. Comparison between overseas and Japan 5. Q&A / Business card exchange

[Speaker] Kazuki Miyamoto, Representative/Analyst, VentureClef, USA [Key Lecture Content] AI development has stepped into the realm of singularity, with technology evolving at an exponential rate. OpenAI will release AGI (AI comparable to human intelligence). President Trump is promoting AI innovation, and a rush to build gigawatt-class AI data centers has begun across the United States. Tesla is entering semiconductor manufacturing, producing AI processors in-house, and equipping them in robots and cars. They are vertically integrating core technologies from chips to AI. The Trump administration has initiated the development of "domestic AI," exporting it to allied countries and launching an initiative to dominate the global market. The AI moonshot project will have an immeasurable impact on the U.S. industry and economy. The ripple effects will spread to the global society, including Japan. Japanese companies are required to understand the U.S. AI megatrend and prepare for this wave. [Lecture Items] <1> Intelligence <2> Infrastructure <3> Hardware <4> Economy
