Reducing your harmful emission output was once a desirable option, then commonplace and now it’s a legal requirement.
There have been ever-increasing regulations put on levels of pollution allowed, this will only become more stringent as the UK target Net-Zero emissions by 2050, and other countries follow the UK's example.
The latest updates to the 'Medium Combustion Plant Directive (MCPD)' have put further requirements that all power generators must comply to - with some exception, see the MCPD section below.
Becoming more environmentally friendly and conscious has never been so much at the forefront of society as it is today. Companies that take the extra steps to cut their environmentally damaging emissions, therefore reduce their negative impact on the planet and carbon footprint, are not only meeting the increasingly strict laws but also without a doubt looked more favourable on by the average customer.
Reducing your pollution should be the main concern for all organisations, both small and large, private or state-run. Products on this website found in the Power Systems Page offer low carbon and emission efficient means of energy generation. Also further down on this page we have information on our advanced active emissions control system, Selective Catalytic Reduction (SCR), which will help make your generators compliant with MCPD. Alternatively, you can speak to us if you would like to discuss your needs and see how we could help you.
Medium Combustion Plant Directive - MCPD
In November 2015 a new directive was signed and approved that regulates emission output on medium combustion plants. This 'Medium Combustion Plant Directive' over the next two decades continue to affect just how the UK can generate power.
For clarification, a Medium Combustion Plant is any form of equipment that burns fuel (with some exceptions) and has a rated thermal input of between 1MW to 50MW - equating to electrical output of between 330kW and 17MW.
The MCPD targets the reduction, control and better monitoring of emission output. To help reduce the effects on the environment and to general human health, by lowering air pollution.
New regulations in the MCPD affect new plants as well as previously installed and commissioned sites that have received a contract with the grid on or after the 20th of December 2018.
Backup standby generators are too included in these regulations. If they run for 50 hours or less and operate only for emergency purposes, then they're excluded from the new rules. However, if these backup generators are also used in grid balancing services or run over the 50 hours, then they must comply.
We can use to make your generator MCPD compliant, while also making your grid balancing services more economically viable, through using SCR - More information below
Selective Catalytic Reduction - SCR
SCR is one of the most fuel-efficient and cost-effective technologies available in helping the reduction of emissions for diesel engines.
It is an advanced active emissions control system that uses a liquid-reductant agent, which is injected through a special catalyst into the exhaust system of a diesel engine. This liquid-reductant agent is a non-toxic fluid, composed of automotive-grade urea and purified water, or otherwise known as Diesel Exhaust Fluid (DEF).
This liquid sets off a chemical reaction in the exhaust that converts nitrogen oxides into nitrogen, water and tiny amounts of carbon dioxide (CO2). SCR technology alone can achieve NOx reductions of up to 98 per cent - as guaranteed by our manufacturer.
An SCR kit not only reduces NOx emissions, there are also reductions in Hydrocarbons (HC) and Carbon Monoxides (CO) emissions by 50-90 per cent, and Particulate matter (PM) emissions by 30-50 per cent. CO2 reductions can also be targeted if requested.
SCR is a tried and well tested technology, having been used for decades to reduce stationary source emissions. Furthermore, marine vessels are regularly fitted with SCR technology, such as cargo vessels, tugboats and ferries. Due to its exceptional returns in both economic and environmental benefits, SCR is used all over the world, often to help meet emission laws. It can now also be found in a growing number of diesel passenger and commercial vehicles.
SCR will help you meet the MCPD requirements and be able to keep you operating as you do now.
If you would like to know about applying SCR onto your generator, then please don't hesitate to get in contact with us to discuss your needs.
