Siddiqui also noted that with time and usage, C4 and C5 can produce byproducts, which themselves are harmful and affect the efficiency and safety of breaker functions. “As regulations change and requirements become stricter, C4 and C5 may fall under future greenhouse gas regulations. According to Naeem Siddiqui, head of Offer Management—Switchgear Americas with Siemens Energy, there are only a few main alternatives currently being used, which include fluoronitrile (C4), fluoroketone (C5), and clean air. Among the items delivered by ABB were advanced converter transformers and components such as bushings and tap changers. The new route was expected to be longer, avoiding the Malacca Strait, while incorporating fueling stations, ports, bridges, industry, and infrastructure through Southeast Asia and into the Indian Ocean.
In this experiment, researchers combined NTT’s beam-shaping technology with MHI’s light-receiving technology to improve the efficiency of laser wireless power transmission. The efficiency of optical wireless power transmission technology is generally low, and improvement of efficiency is an issue for practical use. Microwave wireless power transmission is already in practical use and its use is expanding. In recent years, wireless power transmission technologies for devices such as smartphones, wearable devices, drones, and electric vehicles, which can supply electricity without using cables, have garnered increasing attention. This marks the world’s highest efficiency of an optical wireless power transmission (Figure 1) using a silicon photoelectric conversion element in an environment with strong atmospheric turbulence.
In this experiment, the average electrical power extracted from the receiving panel was 152 W (Figure 4), corresponding to a wireless power transmission efficiency of 15%, defined as the ratio of received electrical power to transmitted optical power. An optical wireless power transmission experiment was conducted on a runway at the Nanki-Shirahama Airport. From January to February 2025, MHI conducted an optical wireless power transmission experiment on a runway at the Nanki-Shirahama Airport in Shirahama Town, Nishimuro District, Wakayama Prefecture (Figure 2).
Strengthening America’s Electric Power Grid: How the Government and Industry Are Improving T&D Systems
That’s why we offer customizable solutions tailored to meet the specific needs and requirements of each application.

Business Overview
For the experiment, MHI optimized the beam design to achieve the desired intensity profile at a distance of one kilometer. In this study, MHI proposed a beam shaping method that enables intensity uniformity after long-distance propagation. From a safety perspective, the optical transmission system and the receiving panel were each installed inside booths to prevent accidental exposure to high-power laser beams and the scattering of reflected light.
