<p>Scheduled for opening in 2022, the Suita Sustainable Smart Town (SST) is Panasonic’s third such endeavor following the Fujisawa SST and the Tsunashima SST in Japan.</p>
<h3>Panasonic’s approach to and goals for its SST projects</h3>
<p>Panasonic’s concept for a sustainable smart town is one where residing families can continue to live in comfort. Rather than focusing on infrastructure technologies, the idea is to create a town with residents’ lifestyles as the main focus.</p>
<p>Bringing together a range of elements – including energy, security, mobility and wellness – Panasonic proposes a smart community that considers residents’ comfort, regional characteristics, and future lifestyles. By designing an entire smart town (including homes and facilities) optimized to these conditions, Panasonic aims to build smart infrastructure to support new ways of living.</p>
<p>Through its development of eco-friendly, comfortable towns that incorporate the gifts of nature and facilitate safe, secure lifestyles over the long time, Panasonic will proactively roll out new smart town concepts both in Japan and abroad.</p>
<h3>Initiatives for the new Suita SST</h3>
<p>Panasonic is currently testing the viability of a commercial-use pure hydrogen fuel cell generator at the Tsunashima SST and the Tokyo 2020 Olympic Village. From April 2022, Panasonic will continue testing at its plant in Kusatsu, Shiga Prefecture, aiming to create an RE100 factory.</p>
<h3>Contributing to reduced CO<sub>2</sub> emissions through sustainable town development</h3>
<p><strong>Fujisawa Sustainable Smart Town</strong></p>
<p>The Fujisawa Sustainable Smart Town (SST) opened in 2014. In this SST, Panasonic is aiming for a 70% reduction in CO2 emissions compared to 1990, and is thus currently engaged in a range of initiatives to achieve this target. These initiatives include the installation of solar panels, storage batteries, and energy-saving equipment in the town’s detached homes, facilities, and public areas.</p>

<p><strong>Tsunashima Sustainable Smart Town</strong></p>
<p>At Tsunashima, which opened in 2018, Panasonic is aiming for a 40% reduction in CO<sub>2</sub> emissions compared to 2005. To achieve this goal, it is promoting efforts to implement systems that save, create and store energy; mutually share energy; increase building insulation performance; and improve energy-saving awareness through visualization of energy usage.</p>

<p><strong>Suita Sustainable Smart Town</strong></p>
<p>The Suita SST is scheduled to open in spring 2022. Through control of demand and visualization of town-wide energy usage, Panasonic aims to promote lower energy consumption throughout the town. In addition, by bringing in energy from renewable sources to cover the whole town’s energy consumption, Panasonic aims to create a 100% renewable energy town.</p>

            <div class="field field--name-field-ces-body field--type-text-long field--label-hidden field__item"><h3>RE100 solution using pure hydrogen fuel cell generators</h3>
<p>Panasonic plans to demonstrate a renewable energy (RE) solution in which 100% of the electricity consumed in business activities is supplied from renewable sources. This is achieved by using an in-house power generation system combining pure hydrogen fuel cell generators, photovoltaic generators and storage batteries. This is the world's first<sub>1</sub> attempt to create an "RE100 factory" through the full-scale use of hydrogen.<sub>2</sub></p>
<p>Equipment composition can be customized depending on installation conditions, and demonstrations are scheduled to begin at an in-house factory in April 2022.</p>
<p><iframe allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture" allowfullscreen="" frameborder="0" height="450" src="https://www.youtube.com/embed/e1RuXfkNrhc" title="YouTube video player" width="800"></iframe></p>
<h3>Use of renewable energy throughout the factory</h3>
<p>Current demonstration of the RE100 solution can generate 2.7 GWh of power. Five RE100 systems can cover the average energy consumption of one Panasonic factory.<sub>3</sub></p>
<h3>Proposing different RE100 solutions based on customer requirements</h3>
<p>Integrated control of the three pieces of equipment required for RE100 (as well as an energy management system) will be demonstrated at Kusatsu RE100. From an ESG perspective, the results of the Kusatsu RE100 demonstration will enable us to propose new solutions to customers requiring 100% renewable energy (factories, buildings, shops, etc.).</p>

<p><strong>Full-scale use of hydrogen to contribute to the achievement of a decarbonized society</strong></p>
<p>Panasonic’s pure hydrogen fuel cell generator boasts the industry’s highest electrical efficiency at 56%. It also has a power output of 5 kW, which can also be increased by linking multiple generators. With a a strong track record in fuel cell batteries lasting many years and a history of outstanding reliability, Panasonic's accumulated expertise has been applied to this new product. Demonstrations are under way in various locations with an aim of creating hydrogen-based society.</p>
<p><strong>In operation and under demonstration</strong></p>
<p>At a demonstration in Yamanashi Prefecture, excess renewable energy generated at a solar power station is used to generate hydrogen, which is then supplied to pure hydrogen fuel cell generators installed at factories and commercial facilities. All three pure hydrogen fuel cell generators, each with an output of 5 kW, can produce approximately 90 kWh in total per day.</p>
<p><iframe allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture" allowfullscreen="" frameborder="0" height="450" src="https://www.youtube.com/embed/e1RuXfkNrhc" title="YouTube video player" width="800"></iframe></p>
<p>HARUMI FLAG, the city complex to be built on the former site of the Olympic Village in Tokyo, will be home to genuine hydrogen infrastructure. Through collaborations with companies in other industries, hydrogen will be supplied via a pipeline to these pure hydrogen fuel cell generators. The city has a total of five blocks, including four residential blocks and one commercial block. Six of these 5 kW generators will be installed in all four of the city’s residential blocks, for a total power generation capacity of 120 kW. The power generated is to be used in the lighting and air conditioning of common areas.</p>
<p><strong>Effective use of energy and a hydrogen-based society</strong></p>
<p>As global use of renewable energy increases, the storage and usage of hydrogen generated through the electrolysis of water using surplus power will also increase. Pure hydrogen fuel cell generators can be used due to their ability to regulate power supply.</p>
<p>The ability to link multiple pure hydrogen fuel cell batteries allows the product to be used for a wide range of applications. Along with the the ability to link multiple units based on space, another advantage includes generating the desired output.</p>
