Biomass Cogeneration Plants for the Hotel Industry

Reduce energy costs, operate efficiently.

The hotel industry is under pressure: The loss of revenue due to the COVID-19 pandemic has not yet been absorbed by a long shot, and energy prices are rising immeasurably.

How are hotels supposed to cope with the costs? After all, it’s impossible to do without energy — guest rooms and spa areas need to be heated, and hot summers cry out for reliable air conditioning.

More and more hotels are therefore switching to a more stable and cost-effective energy supply. Renewable energy sources make this possible.

We compare the most important renewable energies and show you the advantages and disadvantages.

Renewable energies for the hotel industry

If you want to operate efficiently and score points with your consumers, you can’t do without renewable energies.
They have long since proven that they not only benefit the climate, but also help protect businesses from rising energy prices.
For the hotel industry, there are several options for climate-friendly and cost-saving energy generation. What are they? We have summarized them for you:

Wind energy has been an integral part of our power supply for years – its share is over 15 percent (source: The Federal Government of Germany) and it continues to rise. Wind energy is now also available as an energy source for individual buildings. These so-called small wind turbines can do a lot for the climate-friendly image of a hotel – but do not yet convince with their efficiency.

Solar Energy

The large roof areas of hotel facilities are perfect for installing solar collectors and photovoltaic systems on them. Solar thermal systems make optimum use of solar energy down to the last ray of sunlight to generate energy cost-effectively and in a climate-neutral manner. A small restriction: the sun must be shining, of course. So there is a certain dependence on weather conditions and location.

Biomass Cogeneration Plants

Biomass cogeneration plants are ideal for hotels. They operate with maximum efficiency by being able to generate electricity as well as heat and cooling – and they do so using cost-effective fuels such as wood chips and pellets. Another advantage of cogeneration units is that they are highly economical if they are in operation around the clock – ideal for hotels with constant energy requirements.

More and more hotel operators are opting for a combined heat and power plant to generate heat, cold and electricity. The reason is obvious: hotels need a lot of energy, around the clock. Combined heat and power plants can cover just that. In fact, they work most effectively when they are in use non-stop. If a cogeneration plant is operated with biomass such as wood chips or pellets, fuel costs are also reduced, because wood as a fuel is unbeatably cheap.

The energy generated can be used directly by the hotel – excess energy can be sold to the local electricity provider, so additional money can be earned thanks to feed-in tariffs. And not to forget the upgrading and improved green image of your property.

Advantages of combined heat and power plants with wood-fired electricity generation:

Power Generation

Electricity can be fully or partially self-consumed. In addition, electricity can be fed into the public power grid and sold on the free market.

Heat Generation

The heat can be used to heat the hotel, spa or pool. In addition, the heat can be used to produce hot water.

Cooling Generation

In addition to heat, cold can also be produced in combination with an absorption refrigeration system. This can be used as a good complement to air conditioning.

Do you have questions?

We have compiled the answers to important questions for you.

Is a biomass CHP unit worthwhile for my company?

A biomass CHP unit with wood-fired power generation is particularly worthwhile for companies that require constant large amounts of thermal energy for their operations – even in summer. This is because a biomass cogeneration plant is only maximally economical if it operates at full load for a certain number of hours per year. Alternatively, excess heat energy can also be converted into cooling energy in the summer.

What are the requirements for the use of a CHP unit?

Our CHP units generate electricity and heat all year round. Therefore, there should be sufficient electricity and heat demand throughout the year.

Technical requirements:
To ensure a smooth start-up of the system on site, the customer will provide the following on-site installations:

  • Foundation with sufficient access to all system components
  • Sufficient building (if installed indoors)
  • Sufficient air supply with adequate circulation rate (if installed in the building)
  • Three-phase connection with 400 V, 100 A
  • External fuel silo in close proximity to the E5 unit.
  • Space for conveyors and storage
  • Space for ash house for ash discharge
  • Heat extraction (5000 l/h ∆T 25°C)

How much does a biomass CHP unit for wood-fired power generation cost?

A plant for wood-fired power generation is a very individual solution, where the investment costs and also the running costs can be very different. In addition, the various fuels and, if applicable, their processing also result in varying costs. Depending on the application in the process or in the building, different subsidy amounts also come into play, so that a generalization of the total costs is hardly possible.

What fund support options are available?

Companies that use wood-fired power generation by means of a biomass cogeneration plant to generate energy and thus make a contribution to climate protection receive financial support at many levels in Germany. In addition to the feed-in tariff for surplus electrical energy, the German Federal Ministry of Economics and Export Control (BAFA) supports corresponding projects.

The Kreditanstalt für Wiederaufbau (KfW) also supports climate-friendly rethinking with development loans and repayment subsidies of up to 55 percent of the eligible costs. And the individual German states and regions also reward the use of biomass CHP units as progressive and environmentally friendly energy generation.
