Utilisation of geothermal energy in depths above 5 km could contribute considerably to resolving the global problems related to a lack of energy and to glasshouse gases from fossil fuels. The invention describes innovative equipment which makes deep holes in geological formations (rock) by disintegrating the soil into blocks carried to the land surface through the excavated hole filled with liquid, using transport modules yielded up by gas buoyancy interaction in the transport module utilising supercavitation. In an opposite direction—by help of negative buoyancy—the necessary energy carriers, materials and components, or entire devices required for rock excavation, are carried to the bottom. The opportunity to transport rock in entire blocks reduces energy consumption considerably, because the rock is disintegrated in the section volumes only. Some of the extracted rock and material carried from the surface is used to make a casing of the hole using a part of the equipment. The equipment also allows the generation of the necessary high pressure of liquid at the bottom of the hole, to increase permeability of adjacent rock. The equipment as a whole allows by its function that there is almost linear dependence between the price and depth (length) of the produced hole (borehole).

Methanol is produced as a storable and transportable carbon-based energy carrier using at least two different methods. To produce a first methanol portion, water is electrolyzed, preferably using energy from renewable energy sources such as solar or wind power, to produce hydrogen. The hydrogen is then reacted with carbon dioxide to produce the first methanol portion. To produce a second methanol portion, methane is reacted with oxygen. A controller can advantageously be used to control the amount of chemicals in each reaction.

As we move towards a hydrogen economy or use hydrogen as an energy carrier, the need to get heat energy and steam out of the hydrogen is arising more frequently. This invention addresses that need without the atmospheric pollutants which would result from burning carbon based fuels or hydrogen freely in the air. Presented is an invention which has very high overall efficiency and generates no oxides of carbon and nearly zero nitrogen oxide compounds. The generated steam can be used for comfort heating, process heating, electric generation and other common applications requiring steam. The invention can also be used for generation of hot water. The process of steam generation is accomplished by precisely metering the mixing and oxidation of hydrogen and oxygen under controlled conditions. The result of this oxidation reaction is simply only water and heat, which are used to generate steam.
