The COP21 climate conference held in Paris in late 2015 placed climate change at the top of international and economic efforts. Hydrogen and fuel cells are part of the solution to the climate crisis and could become the cornerstone of tomorrow’s energy and transportation systems.

Key industries such as oil refineries, ammonia production, glass production, the food industry, glass, metal and electronics production have been using hydrogen for decades. Market research firm Markets expects the current hydrogen market to grow from the current $ 118 billion to $ 152 billion by 2021. In recent decades, the economic and environmental benefits of hydrogen have led many to promote the development of hydrogen as an energy carrier. In combination with oxygen in fuel cells (electrochemical energy conversion devices), hydrogen can produce carbon-free electricity and heat and water as the only by-product. Hydrogen is a clean and efficient alternative to the conventional fossil fuels it has in abundance.

Cars remain one of the most attractive areas for the application of fuel cells, although it is the application with the most challenges from a technological and economic perspective, as the use of hydrogen as a fuel to generate energy or start up faces a number of challenges.
Namely, hydrogen is not the primary naturally available source of energy, but it is an energy carrier, such as electricity, which needs an external energy source to separate hydrogen atoms from other atoms in complex molecules such as water, hydrocarbons or biomass. Today, more than 95% of hydrogen is obtained from fossil fuels through high-carbon processes, but alternative production technologies are already beginning to emerge, among which water electrolysis in particular provides a promising way to produce green hydrogen – hydrogen produced by renewable energy with low carbon emissions. – and facilitate the integration of renewable energy sources into the energy production system.
In addition to water electrolysis, the solution to the wider use of fuel cell cars could lie in a coordinated investment approach between infrastructure stakeholders, car manufacturers and government bodies globally and locally to ensure a synchronized system of hydrogen production and distribution and fuel cell sales. would solve the problem of interdependence of these two sectors, ie investment in fuel cell filling stations and investment in the production of fuel cell cars. The H2Mobility initiative in Germany and similar projects in Japan and California are good role models for such efforts.

In 2015, the size of the global marine diesel engine market was 33.43 million kilowatts, an increase of 10.2% over the previous year. Global production of marine diesel engines is largely concentrated in China, Japan and South Korea. South Korea mainly produced low-speed diesel engines, while China and Japan focused primarily on medium-speed engines.
In 2015, aided by the growth of vessel production, shipboard diesel engine production in China increased by 15.1% to 16.99 million kilowatts, of which 41.2% were low-speed, 40.1% medium-speed and 18.7% high-speed marine engines.
In China, most marine diesel engines are manufactured under patent licenses. The low-speed engine area is dominated by MAN, Wärtsilä and Mitsubishi Heavy Industries; in the mid-range, Wärtsilä, MAN and Caterpillar had a combined market share of 82%, while the high-speed brands primarily include MTU, Deutz, MWM, SACM, Pielstick, Ruston and Paxman.
The Chinese marine diesel engine market is quite young and underdeveloped in terms of production technology and research and development capacity. As a result, most high-tech motor products remain dependent on imports. In 2015, China imported $ 1.07 billion marine diesel engines and exported $ 94.95 million, with a deficit of as much as $ 970 million.
In the Chinese low-speed engine market, Hudong Heavy Machinery, Dalian Marine Diesel and Yichang Marine Diesel Engine had a share of approximately 95.9%, in the medium-speed diesel engine market Weichai Heavy Machinery and CSSC Marine Power had a share of 58.9%, while are among the manufacturers of high-speed diesel engines primarily Weichai Heavy Machinery, Shaanxi Diesel Engine Heavy Industry and Henan Diesel Engine Industry, of which Weichai Heavy Machinery has a market share of approximately 26%.

To improve competitiveness in the marine diesel engine market, major Chinese manufacturers are working on developing new products.
ReportBuyer’s market research report highlights the following areas:
the size of the market and the competitive environment of marine diesel engines globally and in China;
import and export;
operations and development in China, research and development capabilities and development strategies of 7 global and 16 Chinese marine diesel companies.

Tesloop, a California company that offers transportation services by electric Tesla car, began operations with Tesla Model S in July 2015, which has traveled 200,000 miles (more than 320,000 km) these days. Tesloop began transporting customers from Los Angeles to Las Vegas, and today is expanding its connections and routes and can provide reliable first-hand vehicle information.
The Techcrunch website contacted a Tesloop employee regarding the car. Employee Rahul Sonnad explained that most of the kilometers were covered on the highway, in autopilot mode, and Tesla assures that this does not play any role. Sonnad stated that the Model S battery degraded only six percent, with daily charging to full capacity, while Tesla’s recommended default value is 90%.
However, there were some problems with the vehicle. First, after 30,000 miles, the car informed Tesla of the low engine power. Tesla employees quickly arrived and replaced the front engine.
Another interesting problem occurred after 200,000 miles. The range indicator incorrectly predicted the remaining miles, causing the car to shut down shortly before the miles expired. Tesla explained that this is due to a change in the state of the chemicals in the battery caused by the high mileage. The problem could be solved by updating the car software, which would not be ready for several months, so Tesla solved the problem by replacing the battery and gave us an insight into the loss of capacity after 200 thousand miles.
The only cost of ownership for Tesloop was $ 190 to replace the 12-volt battery and approximately $ 2,500 in tire costs, while Tesla’s eight-year warranty covered everything else. Sonnad pointed out that Tesloop didn’t even have to change brakes after 200,000 miles.

Two new ships designed by Wärtsilä Ship Design were delivered in the second week of September by Wuchang Shipbuilding Industry Group in China. The delivery of these two ships resulted in success for Wärtsilä Design. The contract for all 6 ships was signed back in 2012. Wärtsilä received positive feedback from users who use all 6 ships for important operations. AHTS boats are designed according to Wärtsilä Ship Design’s VS 4612 design, and all meet the specified requirements. The boat has a special design and optimized hull for easier navigation, which results in lower fuel consumption.

The Wartsil Corporation has announced that it will participate in a collaborative project to build autonomous transport ships. The project will improve technology to present autonomous ship transport as a viable option to reduce cost and control. The technology will include artificial intelligence, robotics and remote access to ships. The project is funded by Tekes, the Finnish investment agency and the major corporate investors are Rolls-Royce, Cargotec, Ericsson, Meyer Turku and Tieto. The initial idea is to develop such a transport system for the Baltic Sea by 2025.

Wolfgang Mack, vice president of business development at Capacitor Sciences, claims that lithium-ion battery technology has reached 87% of the maximum energy storage density per cell sold for commercial purposes, and questions future investments in them. He conducted the research after noticing Tesla’s presentation in which it was written that the capacity of the batteries doubles every ten years, and Elon Musk also stated that the capacity of the batteries increases roughly by about 8 to 9% every year. ). Wolfgang Mack’s research shows that in the period from 1995 to 2005 it really doubled in capacity, but from 2005 to 2015 it was not so says, capacity increased by only 16.6%. Mack argues that solar panel and battery technology is almost at its peak, adding that alternatives including supercapacitors should be considered.

MAN Diesel and Turbo has announced a new program that will ensure the sustainability of the company. The program called “Basecamp 3000+” will change the work and strategy of the company and improve price optimization products, their success would reach up to 450 million euros. Under the new plan, each MAN unit will specialize in working in even more detailed areas of work, and some will be refurbished. The work and structure of the company will be simplified. In this program, about 1,400 staff will have the effect of the program.

MAN Diesel and Turbo must deliver three new 18V 48 / 60TS engines to Bangladesh. The units will run a power plant in the Munshiganj district. They see this as a very useful solution in the Dhaka area. This is already the third project that MAN is leading for Doreen Power. The power plant is scheduled to have a capacity of 56.7 MW and will maintain approximately 100,000 households in the Dhaka area with electricity. Alexander Stöckler, vice president, says Bangladesh has developed into a thriving market in recent years. MAN’s 18V48 / 60TS engines will use strong oil and achieve high energy production.

Prošla je 1 godina otkada je otkriveno da je Volkswagen iskoristio software “defeat device” kako bi varali na određenim testovima. Dok Volkswagen pregovara sa radnicima i korisnicima u U.S., već su drugi proizvođači automobila u Europi započeli sličan proces testiranja. Zaključno je da Volkswagen ipak proizvodi motore koji najmanje zagađuju okoliš kako objavljuje grupa Transport & Environment. Renault objavljuje da bi mogli zaustaviti proizvodnju diesel motora u Europi jer su testovi standardnih uvjeta previsoki.

MAN SE, Volkswagen’s German truck manufacturing division, plans to lay off 1,400 workers and thus affect the department’s declining earnings. The head of MAN Diesel & Turbo said that they have to adapt in a continuously demanding market environment, and that the turbomachinery industry is in specific problems and expects orders to remain at currently low levels in the coming years. They plan to increase profits by 450m euros through effective measures, including restructuring. Volkswagen is taking all measures to reduce costs as the car department continues to struggle with the exhaust emissions scandal but is also preparing new technologies such as electric cars. The IG Metall union said separately that in MAN Diesel & Turbo the redundancies include about 1,000 jobs in Germany.
