In addition to — Improving energy efficiency — Environmental benefits related to providing high-efficiency, reliable gas engines we combine — Reducing carbon emissions reduced carbon emissions. — Flexible technology that can be this with the expertise and resources to deliver unbeatable Using a combined heat and power used to provide electricity, product support. (CHP) plant in a hospital is an ideal heating and cooling if required. way of achieving each of these three Whether your requirement is for the supply of a single gas targets. is a clean- engine generator or a complete turnkey power generation burning low carbon emission fuel. facility, we can meet that need. Our ability to add value by A CHP plant facilitates the high efficiency use of this fuel, by Spend less offering an end-to-end service, from initial proposal to recovering not only electricity but reliable long-term maintenance, has led to us becoming a also heat. on energy multi-national company with operations in ten countries and more on across the globe. Our company prides itself on integrity, When a hospital purchases both delivering only the highest quality products whilst providing electricity from the national grid and treatment a reliable accountable localised service. in parallel gas or another fuel for heating this can lead to high costs. Using a gas engine-based CHP plant Benefits of working with Clarke Energy facilitates the purchase of a single fuel Clarke Energy provides flexible solutions for your gas source to achieve both the production generation projects. Our services range from the supply of of electricity and heat. The conversion a gas engine generator, through to the complete turnkey efficiency of a gas engine is very high (>90%) and therefore can result installation of a gas powered generation facility. Clarke Energy in long-term operational cost has a dedicated, top-quality team of sales, , savings for the hospital. project management, commissioning and maintenance staff to meet your needs. We also offer long-term maintenance Hospitals by their nature are high contracts backed up by a strong balance sheet, giving energy consumers. Energy usage in peace of mind with respect to the long-term performance hospitals takes a number of forms including: of your GE gas generation equipment. — Electricity – required to power the lighting and equipment of the facility — Hot water – For cleaning & general use — Steam – For sterilisation, cleaning (more applications needed) — Cooling – For refrigeration, freezing and air conditioning systems.

Each of these energy types can be produced at high efficiency with the assistance of a combined heat and power facility.

Natural gas is an abundant, clean Natural gas generators can be Clarke Energy has a long and low-carbon fossil fuel that can be configured in a number of ways. In extensive experience in the readily utilised for the production of addition to the production of engineering, installation and electricity. The high efficiency of the electricity, generators can also maintenance of combined heat and GE gas engine is well provide heating as hot water or power plants for hospitals. suited to the provision of reliable steam, cooling water and clean decentralised electricity utilising carbon dioxide. The GE Jenbacher gas engine is natural gas as a fuel. — Cogeneration or combined heat known for having the highest levels and power (CHP) of electrical efficiency on the market. The utilisation of natural gas in gas — Trigeneration of combined heat, When coupled with a contractual engines is characterised by the power and cooling (CCHP) maintenance agreement with Clarke lowest carbon dioxide emission — Quadgeneration or CCHP with Energy, it will give peace of mind to levels of all fossil fuels. Due to the carbon dioxide recovery the customer that they will achieve fact natural gas is low in carbon, but — Island mode operation –power the highest levels of availability and has a high hydrogen content, natural production isolated from the have constant returns on their gas has the most favourable carbon electricity grid investment. dioxide balance. The combustion of natural gas produces around Natural gas generation relies upon a 40-50% less carbon dioxide than well-developed and stable natural when coal is burned to produce the gas supply. same amount of energy. Notably it also has low emissions of sulphur dioxide (SO 2), oxides of nitrogen (NOx) and particulate matter.

As a fuel, natural gas is set to become a significant source of power in the coming years. Natural gas is projected to become the most significant fossil energy medium in the next fifty years.
