Agreement with Tokuyama Corporation Concerning Pilot Test of Hydrogen-Powered Absorption Chiller-Heater


EBARA CORPORATION (hereinafter: EBARA) and its group company EBARA REFRIGERATION EQUIPMENT & SYSTEMS CO., LTD. opens in a new tab(hereinafter: Ebara Refrigeration Equipment & Systems) and Tokuyama Corporation opens in a new tab(Head office: Shunan City, Yamaguchi Prefecture; President: Hiroshi Yokota; hereinafter: Tokuyama) have agreed to conduct a joint demonstration test to verify a new hydrogen utilization model using the hydrogen-powered absorption chiller-heater (hereinafter: RHDH model) developed by the EBARA Group. (hereinafter referred to as "Tokuyama") have agreed to conduct joint demonstration tests to verify a new hydrogen utilization model using a hydrogen-fired absorption chiller (hereinafter referred to as "RHDH model") developed by the EBARA Group.

1. Background

Amid the global trend toward decarbonization, studies are underway to use hydrogen, which does not emit CO 2 during combustion, as an effective energy source to combat global warming. Through this demonstration test, the companies will collaborate by taking advantage of their respective fields of expertise to promote the spread of hydrogen-based energy and reduce the environmental burden.

2. Overview

Tokuyama is a comprehensive chemical manufacturer involved in a wide range of products from basic materials to cutting-edge electronics, health, and environmental fields. In conducting this demonstration test, Tokuyama will play a role in providing a stable supply of high-quality hydrogen from the by-product hydrogen generated during the caustic soda manufacturing process. The Ebara Group is an industrial machinery manufacturer that provides technologies and products such as fluid and thermal control in a wide range of fields. In this demonstration test, the aim is to build a model that directly uses hydrogen, and an RHDH type that uses hydrogen as an energy source, developed last year, will be installed at Tokuyama Cultural Gymnasium. The reliability and practicality of long-term continuous operation under actual load will be evaluated by having the product actually provide heating and air conditioning using hydrogen supplied by Tokuyama.

Scheduled start date of examination August 1, 2024
Location 1-1-25 Eguchi, Shunan City, Yamaguchi Prefecture Tokuyama Culture Gymnasium

■About Model RHDH
Model RHDH not only reduces CO 2 emissions by utilizing hydrogen, but also reduces energy consumption by incorporating various new technologies such as variable flow control of cooling water and chilled hot water, energy-saving operation mode, and startup time reduction control *1 In addition, the use of water as refrigerant, which has zero ozone depletion potential and is not flammable or toxic, contributes to the realization of carbon neutrality.

3. Future Plans

EBARA will continue to expand its lineup of hydrogen-fired chiller/heaters as products that directly "use" hydrogen energy and contribute to the realization of an accelerating hydrogen society. Meanwhile, through this demonstration test, Tokuyama will contribute to the realization of a sustainable society by developing new demand for hydrogen for various applications in the chemical industry.
EBARA will accelerate its efforts to achieve carbon neutrality by 2050 and contribute to the realization of a sustainable society as stated in our long-term vision "E-Vision 2030".
 

The EBARA Group will further enhance its corporate value to achieve the Sustainable Development Goals (SDGs) by addressing material ESG issues based on its long-term vision and medium-term management plan.
