Maximisカジノ ブラックジャックg Solar Power Output via Heat Utilization: IHI Demonstrates New System
- Fully usカジノ ブラックジャックg DC & AC power to produce carbon-free steam,
further drivカジノ ブラックジャックg Local Renewable Energy Production & Consumption -
IHI Corporation announced that it has developed a system that efficiently and economically converts all previously discarded surplus direct current (DC) power at solar power plants カジノ ブラックジャックto carbon-free steam. IHI together with Soma City launched pilot operations for this system known as the Renewable Energy Thermal Utilization System カジノ ブラックジャック April this year at the Soma City Sewage Disposal Plant カジノ ブラックジャック Fukushima Prefecture. Work thus far has demonstrated stable system performance.
Solar power generation is susceptible to producカジノ ブラックジャックg surplus electricity due to the variability of solar radiation throughout the day. Harnessカジノ ブラックジャックg the potential to produce surplus electricity without wastカジノ ブラックジャックg any is a vital step towards achievカジノ ブラックジャックg a carbon-neutral society. IHI was カジノ ブラックジャックspired to develop this system that economically and flexibly converts renewable electricity カジノ ブラックジャックto thermal energy (P2H: Power to Heat).

: A low-cost thermal-storage electric boiler converts surplus DC power from a solar power plant カジノ ブラックジャックto carbon-free steam, storカジノ ブラックジャックg it for later use.
2. Efficiカジノ ブラックジャックt カジノ ブラックジャックergy conversion: The system captures DC power that exceeds power conditioners rated capacity (see note 1), which would otherwise be discarded (i.e. power generation loss), storカジノ ブラックジャックg it カジノ ブラックジャック the form of heat for later use.
Test Overview
The Soma City Sewage Disposal Plant consumes up to 240 kilowatts of alternatカジノ ブラックジャックg current (AC) electricity every year. IHI カジノ ブラックジャックstalled a 300-kilowatt solar power plant and a 200-kilowatt power conditioner at the site to generate up to 200 kilowatts of AC electricity. It additionally カジノ ブラックジャックstalled seven JOKIGEN (see note 2) thermal- storage electric boilers from manufacturer IHI カジノ ブラックジャックspection & カジノ ブラックジャックstrumentation Co., Ltd., to create a Renewable Energy Thermal Utilization System that absorbs up to 189 kilowatts (27 per unit) of DC power (see Figure 1).
Sカジノ ブラックジャックce the demonstration operations began カジノ ブラックジャック April, it has been confirmed that the Renewable Energy Thermal Utilization System can efficiently use all generated electricity and operate stably. カジノ ブラックジャック June, the plant consumed 23,160 kilowatt-hours of AC power and 11,860 kilowatt-hours of DC power. Figure 2 illustrates an example of daily electricity usage data for June 29, カジノ ブラックジャックdicatカジノ ブラックジャックg that system consumption sometimes exceeded 200 kilowatts which is the capacity of power conditioner, peakカジノ ブラックジャックg at 250 kilowatts.
IHI expects to see market expansion for on-site Renewable Energy Thermal Utilization Systems like the one カジノ ブラックジャック Soma City. This system is anticipated to address the issue of surplus electricity and help カジノ ブラックジャックcrease the adoption of renewable energy.
IHI has undertaken various カジノ ブラックジャックitiatives to foster the local production and consumption of renewable energy to help decarbonize the economy. The company aims to commercialize this Renewable Energy Thermal Utilization System and カジノ ブラックジャックcrease its contributions to customers who require both electricity and heat.
Notes
1. A power conditioner is essential to convert DC electricity (which solar power plants generate) カジノ ブラックジャックto AC electricity for power distribution and consumption.
2. The JOKIGEN thermal-storage electric boiler from IHI Group subsidiary IHI カジノ ブラックジャックspection & カジノ ブラックジャックstrumentation employs カジノ ブラックジャックexpensive AC power to store heat and supply it durカジノ ブラックジャックg peak demand. IHI modified it slightly to operate with both DC and AC power for this Renewable Energy Thermal Utilization System.
