CHP combustibles

Natural gas, biomethane and propane gas

Natural gas powered CHP units usually do not replace renewable energy from wind and solar power plants. They serve the specific power and heat demand of objects (e.g. hospitals, hotels, factories) or are deployed in district heating networks to balance the fluctuating renewable energies. Therefore they primarily replace the power production from conventional power plants. In combination with their high efficiency CHP units reduce the CO2 emissions by up to 60 % already when powered by natural gas.

Renewable fuels such as upgraded biogas (biomethane) and „green“ hydrogen and synthetic methane (SNG) obtained from renewable electricity, are increasingly being fed into the gas grid. In this way, a climate-neutral CHP operation is possible also with fuel from the gas grid.

Here you will can download our delivery chart for natural gas powered CHP units with all key data (outputs, efficiencies, dimensions, etc.) on one page. Of course our compact CHP modules can also be interconnected to form larger CHP plants.

With some units, propane gas operation is also possible with reduced power. To obtain the corresponding delivery program please contact sales@sokratherm.de.

Hydrogen

The cost-effective, efficient and fully climate-neutral supply of electricity and heat can only succeed by decoupling renewable energy generation and consumption in place and time. To achieve this, a broad infrastructure for synthetic „green“ gases generated from renewable power must be created. Ideally, this will involve the further development of the already existing tightly-knit gas network with ist large-scale storage facilities.

All CHP units built by us can already be operated with up to 20 % hydrogen content in the fuel without any technical adjustments or power reduction. Some series with knock control and adapted engine management can even operate with up to 40 % H2. SOKRATHERM cogeneration units are therefore „H2-READY“ today.

In addition, we will soon provide a first CHP unit with a purely hydrogen-powered combustion engine. Based on this, we will also offer retrofit kits with which existing SOKRATHERM units can be converted to pure hydrogen operation, for example, as part of a planned engine overhaul.

Sewage gas and biogas

The sewage gas generated during the purification process in wastewater treatment plants is very similar to the biogas produced in biogas plants.

Both types of gas can be converted into heat and power in with the CHP units listed in the sewage gas / biogas delivery chart.

Of course also these modules can be combined to form larger CHP schemes or equipped for bivalent operation with natural gas or propane gas or also as an emergency power system to supplying an emergency power rail in isolated operation in the event of a mains failure.

Due to the encapsulation of the CHP units with integrated control and power section in a sound-absorbing case, they are ideally suited for installation in operational buildings.

Delivery and installation in a separate container or concrete space cell is also possible.

Configuration options

Emergency power operation

More power supply safety: Our CHP units can be equipped to provide emergency power in case of a mains failure or blackout.

Configuration options

Containerized CHP unit

We design containers and concrete space cells for the outdoors placement of the CHP unit by your requests - inside and outside.

Configuration options

Steam generation from the exhaust heat

Together with an external steam generation heat exchanger the CHP unit can produce steam from its exhaust heat.

Configuration options

Hot cooling
with 95/80 °C

The heat of a 'hot cooler' compact CHP unit can e.g. be used to power an absorption chiller for trigeneration.

Configuration options

Mobile CHP unit

Our CHPmobile achieves high utilization rates by operating in different sites, e.g. school in winter and public outdoor pool in summer.

more

Configuration options

Zero feed-in control

The zero feed-in control can make effectively stop power from being fed into the public mains by regulating the CHP unit's power production.

more

Configuration options

Heat storage (buffer)

CHP surplus heat can be stored in a heat storage and ceded when it's needed to achieve a smoother and longer CHP utilization rate.

more

Configuration options

Virtual power plant

The SOKRATHERM interface can communitate with the systems of different balancing power providers at lower cost.
