Scientists at Stanford University in the US have discovered great advances in the development of fuel cells. A research team led by Haotian Wang, a former Stanford student, found that compressing a platinum catalyst by just a fraction of a nanometer raises catalytic activity almost twice, which is a very significant fact in the development of clean energy sources. Catalysts are used to carry out chemical reactions faster, with the simultaneous use of less energy. The performance of a metal catalyst depends on its electronic structure, that is, the way the electrons are arranged in its orbit. “Our tuning technology can make fuel cells significantly more energy efficient, and will certainly increase their efficiency,” said Yi Cui, a professor of materials science at Stanford University.

MAN Diesel & Turbo has secured an order for two turbocharged trains for an Iranian refinery south of Tehran. The trains to be delivered are part of MAN’s ReTPac concept (Refinery Train Package) of trains. The engines were ordered by the Iranian company EPC Nargan and will serve in the hydrotreatment process, while ensuring maximum production efficiency. The current order is a clear sign of the success of MAN Diesel & Turbo’s ReTPac concept, which is specially designed for use in refinery production.

Man Diesel & Turbo won the tender for a contract to procure additional diesel engine parts for three new cruisers ordered from Costa Asia and P&O Cruises of Australia. Both companies are members of Carnival Corporation & plc, the world’s most famous company with more than 100 cruisers worldwide. Each ship will have 2 × 14 V 48/60 CR + 3 × 8L 48/60 CR mid-stroke MAN engines that will produce 62,400 kW of power. The engines will be delivered to “Fincantieri shipyards” in Monfalcone (Gulf of Trieste) and to Marghera Venezia at the end of 2019. The three new cruisers that will be provided with new MAN engines weigh up to 133,500 tons, are 323 meters long and can carry up to 4,000 passengers.

MAN Diesel & Turbo has completed the construction of a new power plant in the Solomon Islands, near the capital Honiara, and signed a contract to take full responsibility for the plant’s installations and design. The project was launched with the help of experts from Denmark and Australia. This was one of the largest projects (Lungga Project) in the Solomon Islands in the last 20 years and the power plant will soon restore electricity in Honiara. MAN’s four MAN 9L 27/38 engines will run all the power and add 10 megawatts to the power plant. Solomon Islands has a large number of islands in the southern Pacific. The capital of Hoinara is estimated to have about 523,000 inhabitants.

MAN Diesel & Turbo and MV Werften have already signed a contract for two cruisers that will be equipped with MAN engines, with a registered weight of 200,000 tons each, and these two ships, with 48/60 CR engines of 96,000 kW, will be the largest on market. The ships will be delivered in operation by 2020-2021. years. The ships will cross the southern and eastern oceans throughout Asia, and especially in China. Genting Hong Kong is an active company that has been working with cruisers for 23 years, and they recently announced that they have started new works with the new brand “Dream Cruises”, which will also include ships with built-in MAN engines.

The Australian Antarctic Division (AAD) has selected MAN Diesel & Turbo as its engine supplier for installation on icebreakers and supply and research vessels. The main engines selected are two 16V 32/44 CR motors, both producing 9,600 kW. These engines were chosen for their high reliability and economy – which are characteristics of particular importance in demanding operating conditions, which include temperatures below -30 degrees Celsius, as well as expeditions of extended duration. The icebreaker, designed by Danish marine research company Knud E. Hansen, is produced by Serco Defense, while the first subcontractor is DMS Maritime. The handover of the vessel to AAD is scheduled for April 2020. The new icebreaker will succeed the old research vessel “Aurora Australis” and will have higher cargo capacity, increased durability and operational flexibility, high environmental standards, as well as state-of-the-art research, rescue and supply capabilities. work.

Fincantieri chose MAN Diesel & Turbo to build new engines ordered from Costa Asia and P&O Cruises from Australia. These two companies are part of the world’s largest transportation company Carnival Corporation, with a fleet of more than 100 cruisers. Each boat will have 2 × 14V 48/60 CR + 3 × 8L48 / 60 CR mid-stroke MAN engines, meaning it will produce up to 62,400 kW of power. Each newly built ship will be 323 meters long and weigh 133,500 tons. While choosing the best cruiser engine, the owners of Fincantieri decided to pay attention to the power, safety, redundancy and reliability of the engine.

On October 8, the U.S. celebrated National Hydrogen and Fuel Cell Day, selected according to the atomic mass of hydrogen (1,008), first marked last year. The main areas of application of this technology are fuel cell electric vehicles (FCEVs), which have the potential to significantly reduce US oil use and harmful emissions that contribute to climate change. In addition, such cars can be twice as efficient as today’s gasoline vehicles. That’s why FCEVs are an important part of the U.S. Department of Energy’s energy portfolio that complements other sustainable transportation options.
The beginnings of the development of this technology can be traced back to the mid-1970s and the first oil embargo, when a group of scientists met with leaders from the private sector and the federal government in Albuquerque to discuss possible new technologies. Over time, laboratory scientists have helped teach industrialists the production of optimized electrodes that are the foundation of fuel cells and this collaboration has led to great advances and enabled 40 years later to drive commercial vehicles on fuel cells. In particular, significant progress has been made in the field of this technology in the United States in recent years:
Hyundai and Toyota have unveiled their FCEVs for commercial sale, while several major automakers such as Honda, GM and BMW are working to introduce the same in the near future.
In California, hydrogen is one of the options for refueling at more than 20 gas stations.
The Ministry of Energy co-financed the use of more than 1,600 fuel cells in forklifts and emergency power supplies for mobile phone towers, and the success of these installations led to the use of an additional 18,000 fuel cells without Ministry funding.
Research funded by the ministry has halved projected high costs of automotive fuel cells and quadrupled fuel cell life since 2007.

Solutions that include fuel cell electric vehicles are an important part of reducing global warming to the required levels, and with hydrogen production from environmentally friendly sources, carbon emissions could be reduced by more than 90%.

On October 11, ITM Power opened its fourth public hydrogen car charging station in London. Hydrogen is produced at the Center for Excellence in Engineering and Manufacturing (CEME) in Rainham, East London, by electrolysis of water using photovoltaic energy.
The station is part of a HyFIVE project co-financed by the European Fuel Cells and Hydrogen Joint Undertaking and the UK Low Emission Vehicle Office (OLEV). The aim of the project is to demonstrate fuel cell cars in several European areas through the early use of more than 120 vehicles and 6 hydrogen filling stations. After the first two existing London stations, Rainham is the second London station opened as part of this project. The first opened in Teddington in May this year, and the third is scheduled to open in Cobham. The other three HyFIVE stations are located in Innsbruck, Austria, and in the Danish cities of Aaarhus and Korsor.

In August, the Finnish corporation Wärtsilä signed a contract with the Spanish shipyard Construcciones Navales del Norte SL (LaNaval) in the city of Sestau for the design and delivery of a liquefied natural gas propulsion system for a new RoRo passenger ferry, with the possibility of developing another ship. The ship is being built for the Spanish owner Baleària, a leading carrier serving the Balearic Islands.
The ship should start regular sailing in 2019 and it will be the first RoRo passenger ferry in the Mediterranean and one of the largest ferries in Europe. This environmentally efficient ‘smart ship’ will be 232 meters long and have a capacity for 331 vehicles and 1,700 passengers, of which 70% can be accommodated in cabins. The speed of the ship will be able to reach 24 knots. To ensure passenger comfort, Wärtsilä will apply strict noise and vibration reduction standards to its main and auxiliary engines, propellers and maneuvering thrusters. With natural gas propulsion, the ship’s environmental footprint will be very acceptable as Wärtsil’s solution reduces CO2 emissions by 25%, NOx by 85%, while sulfur and particulate matter are almost completely eliminated.
