HOLZKRAFTWERK CW1800-400x4

The CW1800-400 X4 energy system with Jenbacher engines, which was commissioned in September 2021, have been tailored to meet the needs of wood gas. The engines are the world's first 60-Hertz wood gas engines and deliver 1.8 megawatts of power. This energy system from us uses the waste heat from four Jenbacher J412 engines as well as the heat generated during gasification with a total output of around 2.8 MW of thermal energy for district heating. The combined heat and power configuration allows the Shingu City wood gas power plant to achieves an overall fuel efficiency of more than 90%. In addition, many kilograms of valuable biochar are produced per operating hour, which can be used for barbecuing, as animal feed supplementation or for soil fertilisation.

The use of biomass for decentralised power and heat generation is an increasingly important aspect of the energy transition and fully supports Japan's goals to decarbonise its power sector. Our wood-fired power plants, powered by Jenbacher engines, provide sustainable and reliable energy due to the constant availability of wood.  In addition, INNIO's engines provide a disconnectable power source for the grid to support frequency stability due to the increasing share of intermittent renewable energy sources such as photovoltaics (PV). These plants are optimised for the use of wood gas and offer an alternative solution for decentralised power generation, which is a renewable "green energy". The wood gas CHP plant offers high efficiency in electricity generation as it uses bark and branches as fuel as well as the chopped log wood.

The CHP plant is expected to use about 20,000 tonnes of unused woody biomass from the Kinan region annually. The material will be chipped and used as fuel in the CHP plant, with the heat used to dry the wood chips. The heat from the plant makes it possible to keep drying costs low and use freshly cut wood as fuel. Other uses for the residual heat are currently being explored.

This wood-fired power plant is the first in the APAC region to run with SynCraft technology. The combination of our gasification system with INNIO's Jenbacher engine technology will provide a continuous supply of renewable electricity to the Japanese power grid for the next 20 years. INNIO and SynCraft have had a very good partnership for a long time. The technical teams of our two companies have jointly developed products in terms of performance, efficiency and life cycle costs to achieve the highest possible plant availability.
