Energy generation with ocean waves
Ocean waves have a higher power availability than any other renewable energy source and are available 24 hours a day.
The WEPPC project is a power plant (dual energy converter) that is driven by the floats moved by ocean waves and converts these movements into electrical energy. The WEPPC is the only system that uses the rise and fall of the waves, and consequently can use twice the energy of other systems. All the energy of the shafts is transferred to the generator without losses.
- Due to the confirmed availability of at least 4,500 h of swell per year, the economic viability of the power plant is assured from a calculation point of view; the electricity production is above the multiple of a PV plant with the same nominal power.
- The risk of lower wave availability over the course of a year can be considered very low based on the measurement results provided by numerous studies.
- Nevertheless, the assumed availability of the corrugated walkway was again significantly reduced in the calculation and assumed to be only 50%.

A fuel cell, much like a CHP unit, generates electricity and heat simultaneously.
Therefore, it is similarly efficient as the so-called cogeneration. In contrast to the CHP, both energies are generated by so-called cold combustion. The main product is electric power, the by-product is waste heat.
Fuel cells are primarily operated with hydrogen and take the oxygen from the air. Natural gas and other hydrogen-containing fuels can be used indirectly.
Even though the first fuel cell was developed as early as 1840, it was a long road with numerous field tests before it was launched on the market.
Fuel cell technology is the most efficient way of generating energy to date, but also the most expensive. There is no mass production yet, and fuel cells are not yet economically viable without government subsidies.
In economic terms, renewable energies still cannot be calculated into nationwide timetables and can only be used meaningfully in business terms when supply and demand meet.
Unlike natural gas or district heating, electricity can only be stored at great expense, and converting it into methane, which can be stored efficiently, is even more complex.
On-site electricity storage increases the efficiency of renewable energies and offers further revenue opportunities with marketing via the balancing energy market.
Considering the total yield potential
– In-house power consumption,
– Control energy marketing,
– Straightening of the load curve (purchasing) up to the use of the 7,000-hour rule
electricity storage systems make good business sense and are recommended.
A gas engine heat pump provides heating and cooling at the same time with integrated heat recovery and is particularly resource-saving and economical thanks to the primary energy drive.
Compared to conventional heat pumps, gas as the driving energy offers an ecologically and economically sensible alternative to electricity.
The advantage: In addition to the outside air, gas engine heat pumps use the waste heat generated during operation directly as an additional heat source – and thus achieve a significantly higher thermal efficiency.
GMWP allow simultaneous heating and cooling with integrated heat recovery as a system.
GMWP are universally applicable in new and old buildings. As a stand-alone air-water or air-air system or combined as a mixed system.
There are no interruptions in heating operation due to defrosting phases. This causes hardly any energy losses. You will not have comfort problems and you can use it as the only heat source (monovalent) in the whole house.
GMWP complies with all the requirements of the German Renewable Energies Heat Act (EEWärmeG) and the German Energy Saving Ordinance (EnEV).
Network charges are one of the major items in ancillary energy costs, especially in the eastern German states. Pursuant to Section 19 StromNEV, there are various options for reducing the fixed network charges.
Companies with large energy consumption – 10 GWh or more per year – can apply for a reduction in network charges of up to 80% if they comply with the 7,000-hour rule. So the second requirement is 7,000 full load hours per year.
Many companies and organizations that operate in shifts usually end up with 5,000 – 6,000 hours. Full load hours describe the ratio between annual consumption and peak load.
The idea is to reduce peak loads to the point where 7,000 full-load hours can be achieved. In addition to the announced reduction in network charges, this will also lead to a reduction in the power price and simplify energy purchasing, as the base share will increase.
The reduction of peak loads is the task of load management, which includes active load shedding as well as electricity storage and short-term or even sustainable energy generators.
In total, compliance with the 7,000-hour rule leads to a significant reduction in electricity costs – and an economic benefit thanks to the leveling of load profiles.
Germicidal lighting is equipped with a photocatalytically active coating of titanium dioxide (TiO2). It activates atmospheric oxygen and is extremely effective in decomposing bacteria, viruses and germs. But also unpleasant odors are neutralized.
This innovative coating is safe, proven and certified by renowned testing institutes.
How does the germicidal lighting work?
– Broadband disinfection effect
– Meets all antibacterial requirements
– Has an odor-neutralizing and anti-allergenic effect
– Long-term efficient, without regular renewal
– Controls and inhibits the spread of mold and fungi
– For antimicrobial requirements for use in hospitals, hotels, schools and public transportation.
Companies and organizations that are not entitled to deduct input tax pay sales tax on their purchases – i.e., not only on energy deliveries – and thus, on balance, one-fifth more than the competition.
This is distortion of competition – discrimination against companies and organizations that are not entitled to deduct input tax!
The conversion of energy supply into media supply – for example, from electricity into light or from natural gas into heat – saves sales tax, because media supplies are exempt from sales tax.
This model works without the construction of a fiscal unity and independently of new legal regulations – and independently of existing supply contracts.
The media supplier takes over the existing obligations from the contracts – and thus also the risks of deviations from the load profile – so this model is also compatible with companies and organizations subject to tendering and PPP projects.
Electricity and heat can be produced from natural gas using a CHP unit or fuel cell.
But it also works the other way around:
Electricity from renewable sources can be used to produce methane, which can be stored and transported cost-effectively – and converted back into electricity via a CHP unit or fuel cell.
The original idea of DESERTEC was to generate electricity for the world in the Sahara and to transport it in gigantic cable networks to the world.
DESERTEC 2 simplifies this task:
Electricity from the sun is used via Power-2-Gas to generate methane, which can be distributed worldwide by means of methane-powered ships and used to generate electricity at any location. By means of Power-2-Gas, energy can be generated cost-effectively anywhere in the world and used transportably worldwide.

Do you operate emergency generators due to legal requirements or strategic necessities?
Emergency power systems are anything but inexpensive to purchase and require regular maintenance. Thus, the functionality must be proven on a monthly basis with a test run over one hour and the recording of various performance parameters.
The fact that the electricity fed into the grid is remunerated is little consolation, because in many cases the fuel and personnel costs are significantly higher.
The Energy Cloud enables your emergency generators to participate in the balancing energy market. Deviations from reported electricity consumption are balanced nationwide via the balancing energy market. Both consumers (loads) and generators (e.g., CHPs or your backup grid systems) are paid for both providing (standby) and using (run).
The focus of the Energy Cloud is on the provision of this so-called control energy, the utilization is usually well below 50 hours on an annual average, so that conformity with the emission protection law is maintained. All calls are announced in advance and can thus sometimes replace a maintenance run.
Usually, the – market-dependent – remuneration for the provision is 10,000 euros per year per 1,000 kVA of emergency power. The remuneration for the use is again significantly higher.
The prerequisite for participation in the Energy Cloud is the technical integration of your emergency power systems via a special router.
Low wind turbines are an alternative when there is not enough space for photovoltaics and the heat of a CHP cannot be used.
Currently there are 2 power classes: 250 / 500 kW.
The low tower height of 30 meters simplifies the approval process, since such a plant is not space-sensitive.
The minimum distances are reduced:
– 300 meters to residential areas,
– 40 meters to the object,
– 20 meters to roads (40 meters federal highways, 60 meters highways).
SWEAs pay for themselves faster and are deployable sooner (usually after 6 months).
Depending on the wind speed (4 m/s in Bavaria up to 5.5 m/s on the coast), such plants pay for themselves in less than 9 years, not including rising energy prices.
Cold smart grids enable the widespread use of highly efficient heat pumps, they make it possible to use waste heat potentials and the calorific value effect of CHP units and thermal solar energy, thus working considerably better than conventional heating grids and causing seriously less thermal losses at lower production costs.
This makes them more efficient, more intelligent and can be switched off.
In short: Cold grids make heating networks fit for the future
