Electricity Generator

Summary of Electricity Generator: 

We would like to present a completely new innovative breakthrough technology for generating electricity and cold from low-potential renewable and waste heat energy.

Our technology is based on an absolutely new absorption cycle, in which, unlike others, the generation of electricity is realized even at negative temperatures below the ambient level.

Highly cost-effective autonomous power supply systems of various capacities can be created in that case even at using temperatures of 50-60° C.

The process provides locally distributed and off grid decentralized cooling and energy generation.

The technology is applicable for power supply to individual and industrial consumers.

Project status: 

Our company is developing industrial energy plants, that produce electricity and cooling from ultra lowpotential waste heat. Our technology usues our own  brand new thermodynamic cycle based on a single heat engine (expander) and it  converts waste thermal energy into electrical energy and cooling.

Our solutions can help any traditional power plants and other customers to increase efficiency by 25-30%.

We completed  70% of R&D and created a small prototype with capacity 1kWt. At this stage of our project we are looking for investments to finalize R&D procedures and to set up pilot projects with capacity 100-150 kWt. We see a great interest from our partners from the UAE and South Korea who are ready to provide sites for testing and operating pilot projects.

One of our companies – 'EnTech LLC' Russia was a resident of Skolkovo Innovation Center Russia, http://sk.ru/news, it confirms the incredible level of interest to our solutions.

Description: 

Confidential information.

A new absorption cycle of try generations is proposed. 

The working fluids used here are solutions of low-boiling component (refrigerant) and high-boiling component (absorbent).

The cycle, as shown in Figure 1, includes an expander (turbine) 1 and a chemical compressor consisting of an absorber 2, a pump 3, a solution heat exchanger 4, a steam generator 5, separators 6, 7 and a cooler (heat exchanger) 8. 

The expander is connected on one side to the steam generator (boiler) and the other to the absorber and the heat exchanger (cooler).

In this case, the refrigerant vapor is released from the strong solution at its heating before the turbine and is absorbed by the weak solution after the turbine at its cooling.

Thermal energy is released into the absorption process and the temperature of the working fluid rises. 

The cycle has a two-stage regulation of the composition of the working fluid in the separators 6, 7, and its absorber is equipped of a liquid-steam ejector. 

These features of the cycle make possible to generate electricity and cold with using only one heat engine (turbine) since the cycle has an extended useful temperature range. 

Highly cost-effective autonomous power supply systems of various capacities can be created in that case even at using temperatures of 50-60° C. 

In countries with a hot and humid climate, this technology allows in addition to electricity and cold, to generate a significant amount of fresh water by condensing its vapors from the air.

Local energy sources, such as biomass, solar, geothermal energy, industrial heat waste and the like can be successfully used in this case. Environmentally friendly refrigerants and their absorbents can be used as working body. 

A comparison of some characteristic parameters of the proposed method using an NH3-LiNO3 solution with an ORC cycle (Rankin’s cycle) is shown in the Table.

The experimental technology studies  using a laboratory installation with a power of approximately 1 kW (Figure 2.) show that the technology can be implemented in a relatively short time even with the current state of the art.

The proposed technology allows to significantly increasing the efficiency of generation of electricity, heat and cold from renewable or secondary energy sources and opens up fundamentally new prospects for the further development of clean energy.

Innovative aspect:  

Confidential information.

The new absorption cycle to generate of electricity and cooling, in unlike to the known ones, has a number of characteristic features:

• The generation of electricity and cold is carried out in one heat engine, the expander, at low temperatures, for example, at temperatures from plus 50 to minus 40° C, while the release of the heat at closure of the cycle takes place in the absorber at a higher temperature, for example +30 + 40°C;

• To improve efficiency in the cycle, there is a two-step regulation of the strong solution concentration, the first of which is carried out by a separation or a filtration, and the second by the evaporation. 

• In addition, for the same purpose, the pressure of the exhaust steam after the expander is partially increased by the use of liquid-vapor ejectors using the solution as an injection fluid. 

Such technology is fully environmentally friendly, increases the efficiency of generating energy from renewable or waste heat sources by more than 2 times (from 10-12% to about 20-25%) compared with a similar ORC cycle and can have very wide application.

Benefits:

Our technologies will bring many benefits to the rapidly growing industry of electric vehicles. We can provide charging stations for EV’s with absolutely green, renewable, sustainable and almost free energy. 

Our successful growth will create several types of supporting and partners businesses locally and globally like manufacturing of new type of turbines and generators, heat exchangers, elements of green chemistry, IT solutions and applications , decentralize and off grid power suppliers, new maintenance providers.

No one company around the world has the same level of efficiency – 16-25%  and the same level of capex per  1kW- 500$.

Our nearest competitors are using generators based on Organic Rankine Cycle -ORC, and they have efficiency no more than 10-12 % and capex per 1kW no less than 1000-1200 $.

No one our competitor can generate power and cooling from waste heat colder than 100° Celsius.

We have the highest level of efficiency and capex per 1 kW, and we can generate power and cooling together in a single heat engine at temperatures where no one else works in the world.

We are going to utilize any kind of low potential waste heat energy between 50° and 300° Celsius. There are lots of natural and artificial sources waste heat worldwide:

• Solar heat energy
• Volcanic heat
• Waste heat energy from Data Centers and photovoltaic power fields
• Waste heat from industrial plants
• Waste heat from power plants using any type of fuel, such as natural gas, oil, coal and others

Our technology has  a unique combination of competitive advantages and benefits:

• First of all the process provides locally distributed and fully off grid decentralized  energy and cooling generation.
• Another major benefit is that the power can be generated PERMANENTLY, all day and all night throughout the year.
• Electricity from waste heat are completely renewable, sustainable and unlimited resource 
• Production costs are well below traditional generation  methods

Our technologies are original and breakthrough.

IP ownership:

Our technology is patented and protected from being copied and we use only our own technology  and R&D. 

Additional information:  

Our next step is to produce prototype with capacity  100 kWt and set up a pilot projects in the EU and MENA and other regions across the world.

After that, we will sell our energy systems directly to end users according to their needs and also through professional dealers network and associations.

We will sell our energy systems to any level government energy authorities , power plants, data centers, PV farms, industrial plants with huge amount waste heat energy, R&D centers and universities, charging stations for EV’s and others.
