Electricity generation, transmission and distribution

1. Completely cease the use of coal in electricity generation. The share of coal should not exceed 10% and be reduced to zero by 2025.

Reasons:

  1. use of coal in electricity generation: 5 billion tonnes per year
  2. greenhouse gas emissions: 13 billion tonnes of CO2 equivalent per year
  3. coal-fired power plants account for 37% of global CO2 emissions and 72% of total greenhouse gas emissions in the electricity generation sector
  4. the amount of harmful substances emitted into the atmosphere leads to premature death - about 3.7 million people
  5. mutation and destruction of some fish species, amphibians
  6. freshwater consumption and pollution.

2. Reduce the use of oil in electricity generation by 10% annually within 10 years.

Reasons:

  1. use of oil in electricity generation: 220 million tons per year
  2. greenhouse gas emissions: 650 million tons per year of CO2 equivalent.

3. Use electro-plasma instead of regent technologies at thermal and nuclear power plants - water softening and desalinization for thermal and nuclear power plants*.

Reasons:

  1. high energy consumption for maintaining power plants
  2. presence of acidic and alkaline sewage waters

* Water softening and desalinization for thermal and nuclear power plants.

The introduction of reagent-free electro-plasma technologies for preparing softened water for feeding heating systems and desalinized water for boilers of electric power units makes it possible to:

  • eliminate the use of reagent facilities (for iron sulfate, alkali, acid, etc., their transportation, warehousing and storage, the preparation of reagent solutions, as well as the maintenance and repair of tank facilities and pumps);
  • exclude preliminary water heating up to 40°C, reduce water consumption for own needs;
  • eliminate ion filter regeneration, acidic and alkaline effluents;
  • eliminate the use of expensive ion resin;
  • reduce the cost  of maintenance and overhaul by 80%;
  • reduce electricity consumption for technological needs;
  • automate the technological process, which will significantly increase the reliability of equipment operation, improve the working conditions of maintenance personnel and reduce their number 5-6-fold;
  • eventually reduce the cost of water treatment 3-fold;
  • obtain ultrapure and desalinized water with an electrical conductivity of 0.06-0.08 μS/cm* and Si02<20 μg/l.

*microsiemens; siemens - unit of measurement of electrical conductivity.

Experience has shown that use of the above-mentioned ultrapure water reduces the corrosion rate of the equipment 10-15-fold compared with water that has a conductivity of 0.15-0.20 μS/cm, which is characteristic of existing reagent water treatment technologies.
