PHOTOVOLTAICS

The sun is an important renewable energy source: emission-free, inexhaustible and free of charge.
The photovoltaics systems nowadays have a long service life (up to 30 years), pay for themselves after a few years and can be recycled up to 95% .
In combination with storage technologies (battery, P2G, etc.), their use can be evened out.


SOLAR THERMAL ENERGY

Solar thermal energy is the energy that harnesses the heat from sunlight and converts it into usable thermal energy. A solar thermal system uses the energy to heat drinking water and feeds it into a buffer storage to support the heating system.  Advantages are similar to the ones of Photovoltaics.

COMPLEMENTARY TECHNOLOGIES

"Hybrid projects" are characterized by the fact that they combine different technologies (generation, storage, geothermal energy, etc.).
enso also deals with the topic of the optimal combination of energy sources in all projects: Hydropower + solar energy, solar + hydrogen and other hybrid concepts.


GREEN AND TURQUOISE HYDROGEN

• Green hydrogen is produced by splitting water, with the energy for electrolysis coming entirely from renewable energies. As no greenhouse gases are emitted during the production of green hydrogen, it is considered a climate-friendly alternative to fossil fuels.

• Turquoise hydrogen, which can be produced energy-efficiently from natural gas, represents a CO2 - neutral production, and even a CO2 - reduction if biogas is used. In addition to hydrogen, the process also produces pure graphite as a usable by-product.

Green/turquoise hydrogen, also in the form of e-fuels, offers enormous potential as a raw material, energy carrier and storage medium to contribute to the decarbonization of energy- and CO2-intensive processes. Possible applications are in transportation (where electrification is not possible or sensible), in industry and in heat supply.

STORAGE TECHNOLOGIES

The ability to store electrical energy is the pivot point of the energy transition. Because only if we can store renewable energy will we be independent of time, supply and demand. There are several forms of storage available, such as

• Pumped storage
• Green hydrogen
• Power-to-gas
• Battery as short-term storage

HYDROPOWER

Investing in hydropower means investing in an economical, environmentally friendly and socially responsible way.  Hydropower is a proven, sophisticated and economically competitive technology.

• Hydropower is efficient: Hydropower is able to achieve an impressive efficiency rate (ratio between energy generated and used) of between 65% (pumped hydropower plants) and 88% - dwarfing all other technologies (wind, solar, thermal power plants) showing efficiency rates between 30% and 40% only

• Hydropower is reliable: it flows in any weather and at any time of day – water flow is on the one hand seasonally depending but on the other hand highly predictable and available 24 hours - balancing out short-term fluctuations, which in turn ensures security of supply

• Hydropower is social: quality of life improves, jobs and apprenticeships are created, infrastructure is improved (e.g. in countries such as Turkey, Albania)

• Hydropower is ecological: construction in harmony with nature, CO2-free, very little structural intervention for power plants up to 50 MW - we attach great importance to adapting to the environment and architectural styles.

WIND ENERGY

The advantages of wind energy: unlimited availability (in the right locations), no pollutant emissions, contribution to climate protection through sustainable and clean electricity without polluting the environment and wasting resources, increasing independence of supply and contributes to decarbonization.
