Sankei Building's Strategic Investment in Clean Planet

Sankei Building, a leading real estate developer based in Chiyoda, Tokyo, has announced its strategic investment in Clean Planet, another Tokyo-based company, to advance the application of quantum hydrogen energy. This collaboration aims to foster sustainable real estate development by incorporating next-generation clean energy technologies into their projects.

The Imperative for Carbon Neutrality by 2050

With the increasing focus on achieving carbon neutrality by 2050, reducing the environmental impact of electricity consumption in office buildings, residential complexes, hotels, and data centers has become a critical challenge. Enter quantum hydrogen energy, developed by Clean Planet. This innovative energy source boasts a significant advantage: it is affordable, produces zero CO₂ emissions, and can be deployed virtually anywhere while extracting immense thermal energy.

Sankei Building recognizes this technology as a potential game-changer for addressing energy issues in the pursuit of sustainable development. By utilizing quantum hydrogen energy in its owned and operated buildings, the company envisions a future where energy is produced and consumed on-site, promoting local energy self-sufficiency. This approach not only supports sustainable urban development but also ensures energy availability during disasters.

About Clean Planet

Clean Planet, founded in September 2012, has made significant strides in the realm of next-generation energy commercialization. The company emphasizes three pillars: safety, stability, and affordability, as it pushes towards practical implementation. Since its inception, Clean Planet has collaborated with Tohoku University, laying a robust research foundation. Transitioning to a commercialization phase in 2020, the firm now holds 151 patents across 35 countries, reflecting its exceptional technological prowess and intellectual property.

Their technology is versatile, applicable as heat sources in boilers or as part of energy generation systems, and holds promise not just for the industrial sector but also for urban infrastructure. As cities turn to decarbonization strategies, Clean Planet’s offerings are positioned as pivotal solutions in the energy landscape.

Partnership Goals

Through this investment, Sankei Building aims to support Clean Planet's growth and facilitate the societal integration of quantum hydrogen energy. The company will leverage its office buildings and hotels as experimental fields to assess the feasibility of transitioning existing heat source systems to quantum hydrogen energy systems.

By identifying and addressing practical challenges from a real estate developer's perspective, Sankei Building seeks to provide innovative energy solutions that contribute to decarbonization. This endeavor is aimed at generating new environmental values that benefit tenant companies and users alike. Ultimately, this partnership aspires to accelerate the realization of “next-generation sustainable urban development.”

Comments from Leadership

Toshinori Abe, Senior Executive Officer at Sankei Building, expressed:

“As developers, our mission is to adapt to the changing times and create valuable real estate for future generations. We firmly believe that the quantum hydrogen energy developed by Clean Planet has the potential to revolutionize existing energy concepts and could significantly influence future real estate development outcomes. We hope that our partnership will greatly contribute to the creation of safe, sustainable urban environments.”

Hideki Yoshino, President of Clean Planet, added:

“We are sincerely grateful for the strategic investment from Sankei Building, one of Japan's leading developers. Our quantum hydrogen energy is ideally suited for urban use as a clean energy source. With insights from Sankei Building’s extensive experience in urban development, we are committed to expanding this Japan-origin technology as a social infrastructure and contributing to a decarbonized society.”
