Energy service contract – effective practical application.
The introduction of own energy sources at the enterprise is often slowed down not only because the customer does not have a sufficient number of working capital or the unavailability of loans. The operation and maintenance of the plant on its own requires qualified specialists and imposes an additional burden on the power engineering department of the enterprise. In this case, the best solution may be an energy service contract. As a result of its implementation the customer receives a reliable energy supply and significant cost savings without being distracted from the main activity. Since 2019 GreenTech Energy company has been actively and quite successfully developing this area concluding energy service contracts with various enterprises.

Hydrogen application for power generation: ecological issues.
The energy sector is in a constant state of change, perhaps more than ever.
Stricter emissions requirements have come on the
heels of shifting public support for environmental sustainability. Gas turbines are now expected to burn more variations of fuel and be more flexible in their application, all while competing with wind, solar, and battery storage systems. Alternatives to natural gas like hydrogen have garnered intense interest due to clean burning qualities and government support. Accordingly, most manufacturers offer turbines that can handle some level of natural gas-hydrogen blend. They are working to create future-proof turbines that can efficiently run on 100 % hydrogen or a high hydrogen blend.
Transition process to
hydrogen power generation is called decarbonization.
Many developed countries
endorsed the programs of hydrogen technologies development support.
These technologies are first
of all the technologies of green hydrogen generation. It is produced from the water by means of electrolysis with using electric power generated by renewable power stations.

Update on the extended engine portfolio of Anglo Belgian Corporation.
Now ABC is more than 100 years old and it still strongly believes in the need for internal combustion engines. In the old days, the focus was mainly on fuel consumption, but this has changed dramatically. Now, the market asks mainly for higher power output, lower consumption, lower emissions and a diversity of utilized fuels such as bio-fuels, gas, low sulfur heavy fuel, etc.
Although this clearly
increases the complexity of the engine, a simple engine design with easy maintenance and operation is the key for customer satisfaction. In these conditions, ABC has followed its clients and has a new D36 engine range available with a power output of 650 kW/cylinder at 750 rpm, for as well marine as power generation applications. This engine is equipped with the latest technology such as common rail, a double stage charging system, exhaust gas recirculation and variable valve timing which results in a low fuel consumption with low emissions.

Creating a high-performance water pump for power plants on the base of DM21/21 engine.
The decision to develop and create a high-performance water pump for power plants was made by design bureau of Ural diesel-motors plant due to the use of diesel engines in power plants with increased resistance of the cooling system radiators. That is why it was necessary to increase the pressure and flow rate at different engine operating conditions.
The hydrodynamic calculation of the flow part of the serial pump is carried out. A new
impeller design is proposed to achieve the necessary pump parameters. The hydrodynamic calculation of the flow part of the upgraded pump is carried out. The results of tests of the upgraded water pump on the non-motorized stand of the enterprise are presented.

Biogas power station for pulp and paper mill in Austria.
For 125 years, AustroCel Hallein has been wellknown for high-quality cellulose products at Hallein Location. With the production of environmentally-friendly textile pulp and the use of the side streams resulting from this in the form of bioenergy, the company has positioned itself as a forwardthinking industrial company. In 2016 it was decided to construct biogas power station on the site of the enterprise. Under the contract MWM Austria GmbH supplied TCG 2032 V16 gas engine power plant rated at 3.77 MW to the site. The main advantage of the MWM TCG 2032 gas genset units is a high fuel utilization ratio and low operating costs. This was achieved thanks to the improved spark plugs.
Result is large inter-service intervals: the first maintenance – after 4,000 hours, overhaul – after 80,000 hours. The consumption of lubricating oil is 30 % lower than that of the competitors. The station operates in cogeneration cycle and generates electric and thermal power for technological needs of the enterprise. It uses biogas generated from industrial wood residue as the main fuel.

Automotive components: experience of their using for gas engine power plants.
Gas engines are widely used not only as the drives for power stations but also in automobile transport.
This circumstance leads to the unification of many consumable parts. To what extent this is legitimate and whether it is possible to use cheaper car parts as part of a power plant, the author considers on the base of the presented material. First of all, it is necessary to determine what is the main difference between the engines used in road transport and in gas engine power plants.
Operating mode is the most important and fundamental difference between automotive and industrial gas-piston engines. In the first case, the engines are designed to operate in a mixed load cycle, with a short-term achievement of 100 % power as opposed to power plants. 

Golden lightnings, the main prizes in the sphere of small-scale distributed and alternative power generation, have been awarded in Moscow.
The solemn ceremony of the VIII Distributed Power Generation – Great Achievements International Award took place in the Congress Hall of the Chamber of Commerce and Industry of the Russian Federation in Moscow on December, 11. The highprestige Award for the best project in the field of distributed and alternative power generation was established by the Russian Distributed Power Generation Association with the support of the Business Russia business community, the Ministry of Energy of the Russian Federation, the State Duma Energy Committee, and sparked a great interest of the industry related energy enterprises and representatives of business and government. The ceremony held in the capital city of Russia was attended by representatives of more than 50 companies, finalists of the Award. The Internet broadcast of the ceremony on the website of the Distributed Power Generation Association attracted the attention of over a thousand people.
72 projects have been included into the shortlist of the Award.
