FAQs

What applications can I use fuel cells for?

Logan Energy can provide fuel cell installations for both small scale (less than 30kWe) UPS system and small (5kWe) to large scale (50MWe) prime power installations as an integrated energy centre. Fuel cells can be used as a form of CHP (Combined Heat and Power) or CCHP (Combined Cooling Heating and Power) in applications that have a relatively constant heating/cooling load.

Transport solutions can also be provided.

What sizes of fuel cells do Logan Energy have available?

We have a wide range from 1kWe to 50MWe. Logan Energy does not manufacture cells but have close relationships with the manufacturers and an extensive understanding of installations built up over the last 15 years. This allows us to remain independent of products and manufacturer and select the most appropriate solution for our clients.

What are the prices compared to traditional internal combustion engines?

Fuel cells will have a higher initial capital cost, but with a life expectancy of 20 years they will provide savings over the full lifecycle when compared to a traditional internal combustion engine.

Are there different types of fuel cells?

Yes, the fuel cell sector has a wide range of different technologies, each have their place in different applications. Logan Energy has the knowledge and experience to design and install systems utilising the most appropriate technology to obtain the most efficient, cost effective solutions.

What fuels do they run on?

Pure hydrogen is not necessarily required. Many fuels with a viable hydrogen source can be utilised, for example, natural gas, digester gas, waste streams from manufacturing, methanol and LPG. It is also often possible to blend fuels if the need arises.

Depending on your application, it may be easiest in the first instance to use natural gas (e.g. due to existing natural gas connections), then move to alternative sources as they become more available or financially viable.

What are the carbon savings?

Using natural gas as a fuel we are achieving 40% savings when compared with the conventional grid electricity and gas boilers. Using renewable fuels this obviously becomes 100%.

How do efficiencies of fuel cells compare to internal combustion engines?

Due to fuel cells using a chemical reaction rather than a combustion process, fuel cells deliver the highest efficiency of any form of distributed generation. For example:

Natural gas engines 30- 42%
Direct fuel cell/turbine 58- 65%

Efficiencies are higher again when the fuel cell is considered as a form of CHP/CCHP.

Do Logan Energy have many fuel cell systems operational in the UK?

Yes, we have a number of installations across the UK, we are happy to set up a visit to an installation. Additionally, the fuel cell in the Transport for London Palestra building in London is housed in a display pod at the entrance and is available for public viewing. It has been operating since February 2009.

Are fuel cells reliable?

Fuel cells are highly reliable, partly due to the fact that there are no moving parts in the fuel cell stack. Depending on the specifics of the system, generally there will be a light maintenance check each quarter, with annual more extensive maintenance; Logan Energy can also provide these maintenance services.

Many of our clients choose fuel cells to provide essential power in the event of grid failure due to the high reliability and security of supply.

How do I evaluate if a fuel cell is right for my building?

The Logan Energy team can carry out an evaluation of your requirements and present our proposals. We will only propose fuel cells if they are appropriate for your needs.
