Geothermal Power

Environmentally friendly and stable geothermal energy can generate electricity throughout the years regardless of weather conditions. Yokogawa has participated in dozens of geothermal power projects in Japan, Southeast Asia, Africa and other regions, providing a variety of measurement and control technologies.

Biomass Power thumbnail

Biomass Power

Biomass can help thermal power plants reduce their carbon dioxide emissions. Yokogawa measurement and control technologies are used all over the world in many types of biomass power plants.

Waste to Energy thumbnail

Waste to Energy

Waste-to-energy (WTE) technology provides an environmentally sound solution to an ever-growing challenge of waste disposal in urban areas. It also addresses the growing need for alternate energy sources. Yokogawa systems that over 150 WTE plants and other types of waste incineration facilities count on play a key infrastructure role in making our world cleaner and more efficient.

Wind Power thumbnail

Wind Power

A great many wind farms with large numbers of wind turbines have been constructed in recent years around the world, and offshore wind farms are now becoming popular. Yokogawa provides solutions that help to ensure the stable power supply by making operations more efficient and by enabling remote and centralized monitoring of multiple wind power generation systems.

Hydro Power

Hydropower is the most widely-used renewable source of energy and plays a major role in electricity generation in some regions. Yokogawa supplies control and instrumentation products and solutions for hydropower plants around the world.

Ocean Thermal Energy Conversion thumbnail

Ocean Thermal Energy Conversion

Ocean thermal energy conversion (OTEC) is a unique technology that utilizes the temperature difference between the ocean surface and deep ocean water and is applicable in tropical and sub-tropical coastal regions. Its capability to generate a stable supply of electricity around the clock makes it well suited for meeting baseload demand.


Industrial hydrogen fuel cells can be used to produce hydrogen and oxygen from distilled water as well as run in reverse to generate electricity. Fuel cells can also be used in conjunction with intermittent energy sources like solar or wind to provide regulated continuous energy output.


Geothermal power plants create electricity from geothermal energy. These power plants are similar to other steam turbine station; however their heat source is that of the earth's core. The created steam is used to turn the turbine for the production of electricity. Technologies include Dry steam, Flash steam and Binary cycle power stations with Binary cycle being the most common geothermal plant in current production. In the process of geothermal power generation the facility needs to monitor various processes, as in this case steam line pressure sits in remote from control room's location.


A manufacturer of lime using an Allen-Bradley Series 5 PLC wanted local data viewing and network connectivity. The PLC was wired directly to a rotary kiln and measured kiln temperature, pressure, rotary speed and material feed rate.


Yokogawa’s industrial automation (IA) product and service offerings, industry domain knowledge, and VigilantPlant approach – which emphasizes safe, secure, and uninterrupted operations -- provide a solid foundation for an Industrial Internet of Things that specifically addresses the requirements of process automation, particularly for the OT side of the equation. To be able to provide an equally solid foundation for the IT side, Yokogawa is partnering with Cisco Systems and other industry leaders.


This white paper provides an overview of how Yokogawa believes its customers can best prepare for and position themselves to benefit from IIoT-enabled technology and solutions and digitalization in general to emerge as the successful connected industrial enterprises of the future.


The worlds of process automation and production management have been converging for some time. What once used to be islands of automation and production management functionality connected through highly proprietary integration schemes that were costly to maintain have developed into integrated platforms that provide seamless data exchange between the world of automation and the plant floor, the functions of production and operations management, and integration with business level systems.


The automation suppliers that will be successful in the long term will be those that effectively address application or industry specific problems for end users with a value proposition that cannot be ignored. These problems exist throughout the process industries today, and they won't be solved by simply offering a product, but through a combination of hardware, software, services, application expertise, and knowledge.


In ARC's view, customers need a compelling business value proposition to justify investment in any kind of automation. Vigilance and VigilantPlant were created with this in mind. Yokogawa's vision with VigilantPlant is to create an environment where plant personnel and operators are well informed, alert, and ready to take action. 


Yokogawa has come a long way in making its message clear to the world of process automation. Last year, the company embarked on a full-scale global marketing campaign to make customers aware of the company's focus on system reliability, security, dependability, and robustness. Dubbed "Vigilance", the campaign created a unified message for the company and greatly helped expand awareness of the Yokogawa brand and corporate philosophy.


Process automation end users are under more pressure than ever to do more with less. The current economic climate means that many automation capital projects are on hold. With capital budgets tighter than ever, users instead focus on operational budgets (where cost cutting is also a key concern), or on automation investments with a very rapid return on investment.


In today's dynamic industrial marketplace, the only constant is change. Raw material costs, energy costs, market demands, environmental and safety regulations, technology, and even the nature of the labor force itself are constantly changing, and not always in predictable directions.

Yokogawa Technical Report

Environmental friendliness (E) must be assessed in today's product design in addition to the conventional design considerations of quality (Q), cost (C), and lead time (D). Hence, the product design system must be urgently restructured in order to minimize the environmental impact of a product throughout its life-cycle from purchase of the materials and parts, through manufacturing and distribution, to use and disposal.
