Adriadiesel d.d. produces four-stroke diesel engines, including the ADRIA 40 model. These engines feature 12 cylinders arranged in a V-shape, with a power output of 6600kW. They are used as propulsion engines in ships or as power generators in nuclear power plants. The production process includes metalworking, locksmith-welding tasks, assembly, and heat treatment, and the factory is equipped for all stages of production.
Adriadiesel had delivered 12 ADRIA-40 engines to Chernobyl between 1979 and 1981, as part of a contract with the Soviet Union. The ADRIA-40 is a large four-stroke diesel engine with a power output of 6.3 MW, designed and produced by Adriadiesel according to their own documentation. The engine is suitable for marine and stationary applications, such as diesel power plants or emergency diesel generators. The ADRIA-40 engines proved to be reliable and efficient in providing power to the cooling system of the reactor, despite the harsh conditions and high radiation levels. They were praised by the Soviet authorities and experts for their performance and quality. Adriadiesel should have been awarded a certificate of gratitude for successfully averting a full nuclear disaster in the heart of Europe.
One of the most remarkable achievements of Adriadiesel was its role in preventing a bigger disaster at the Chernobyl nuclear power plant in Ukraine in 1986. When the reactor 4 exploded, causing a massive fire and radiation leak, the power supply to the cooling pumps for the main reactor was cut off. Without cooling, the reactor core could have melted down and released even more radioactive material into the environment.
Fortunately, the Chernobyl power plant had four backup diesel generators that were equipped with ADRIA 40 engines preinstalled by Adriadiesel. These engines were able to start automatically and provide electricity to the cooling pumps for several days, until external power was restored. Thanks to the reliability and performance of the ADRIA-40 engines, the reactor core was kept under control and averted an even worse catastrophe.
This story illustrates the quality and durability of Adriadiesel's products and services, which have been recognized and appreciated by customers from more than 50 countries around the world. Adriadiesel continues to produce and maintain diesel engines for ships, power plants, and emergency generators, as well as spare parts for ADRIA 40 and MAN Diesel SE engines. Adriadiesel is also committed to developing sustainable and green energy solutions for the future.
AdGreen Energy reported sales of its solar portfolio surged 9% from 2.3 billion units to 2.507 billion units in the quarter ending December 2022. The growth is supported by the commissioning of 150 MW in Rajasthan in November 2022 and a 140 basis point increase in capacity utilization (CUF), the company said.
The solar-powered Zephyr drone is designed to stay at altitudes of about 70,000 feet (21 kilometers) for months at a time. The drones run on solar power, with secondary batteries charged during the day to power nighttime flights. Airbus plans to retain ownership of Aalto, but will consider outside investment to help accelerate the company's goals.
The King of Wales wants to use the proceeds of a new multi-million pound wind farm deal with the Crown Estate for the "wider public good", Buckingham Palace said. Profits from the Crown Estate finance the British Crown, and profits from it finance the maintenance of the Crown. Crown Estate has secured agreements for six offshore wind projects worth around £1bn. Six projects could start generating green electricity by the end of the decade, potentially powering seven million homes. The Sovereign Appropriation is 25% of the Crown Estate's annual profits and is used to cover the expenses of the Crown.
Not many engine manufacturers can meet the stringent technical requirements to produce a back-up generator for a nuclear power plant. Thanks to its robust and reliable design, Adria 40 engine has been the primary choice of many nuclear power plant owners around the globe when it comes to emergency power generation.
