How to Cool a Nuclear ReactorVIDEO ON THE TOPIC: Big Engines Starting Up
Air quality regulations that come into force next year are making water and wastewater companies reconsider the role of diesel equipment in their operations and energy strategy. Poor air quality may not be as visible or obvious as other forms of pollution, but it has a serious impact on all of us, and it is an area in which the UK has a problem.
London recorded concentrations of micrograms of nitrogen dioxide NO2 per cubic metre of air in , compared to the EU safety limit of 40 micrograms. And the capital was not alone - 16 urban areas, including Birmingham, Leeds and Glasgow, were found to have regularly breached limits in a recent legal case brought by the European Commission. Some water utilities own hundreds of diesel generators, which are used as back-up energy sources where needed and are also turned on to avoid peaks in energy prices triad avoidance and as part of demand-side response DSR initiatives.
Yet making these diesels compliant with the three emission types controlled by the MCPD — nitrogen oxides, sulphur oxides, and particulates dust — is likely to involve significant cost.
So will water companies need to rethink their use of diesel entirely? New equipment will have to be compliant with the emissions rules from December But most of the question marks surround the use of existing assets, which will need to be made compliant from onwards, by an exact date which depends on their size and usage.
The problem is that the cost of the technology required to clean up the emissions from these generators may be disproportionate to their value. Many generators are switched on for short periods to avoid using grid electricity during triad periods — times when power from the grid is at its most expensive. Until recently, Environment Agency guidance was that triad avoidance counted as a balancing service, and so unabated diesel generators would be barred from being used in this way.
However, in May the EA made a U-turn on this and confirmed that triad avoidance did not count as a balancing service. Switching to diesel generation during triad periods can be very financially attractive for water companies, so it is likely that many will impose extra operational controls to ensure they keep within the specified 50 hours.
However, some water company sources contacted by WWT believed that the days are numbered for even this kind of activity. It addresses a perceived gap in the control of emissions because larger plants over 50MW are already covered by the Industrial Emissions Directive, while smaller appliances such as heaters and boilers are covered by the Ecodesign Directive. New plants will have to be compliant from 20th December ; all existing plants of over 5MW must be compliant by 1st Jan ; and all existing plants over 1MW must comply by 1st Jan Some water companies have a large numbers of such generators which they use as back-up power sources and as a way of making money through demand-side response DSR arrangements, through the mechanism known as the Capacity Market.
In order to maintain a robust and economical energy supply to our treatment and network facilities, we employ a variety of strategies and technologies. In addition to the renewable energy from our solar and wind turbine business, we also have around diesel generators, and a fleet of combined heat and power CHP engines across our sludge digestion facilities to provide a level of energy resilience.
As a company we continually look for innovative ways to utilise our assets, which benefit our customers either through the services they receive, or bills they pay. The introduction of the MCPD and Specified Generator Control Regulations has required the company to review the impact of these requirements across our business, especially the impact on our diesel generators and the functions that they perform. A cost benefit analysis is being carried out to determine if it is economically viable to upgrade the engines to meet new emission standards, or if we apply operational controls.
In the short term diesel generators will continue to provide a cost effective solution to provide emergency back-up to key water and wastewater facilities, although the continuation of these engines in the energy market is limited.
Longer term, United Utilities is looking into alternative technologies such as batteries, and bio-diesel generators. With vehicle emissions being a major contributor to poor air quality, commercial vehicles are increasingly being required to comply with rules introduced at a city level — examples being the London Ultra Low Emissions Zone set to come into force in April and a mooted plan to ban diesel and petrol cars from Oxford city centre in For this reason, and to boost the overall sustainability of their businesses, some water companies are seeking to become early adopters of electric vehicles.
United Utilities recently announced an ambitious plan to switch its entire fleet of vehicles from diesel to home-produced energy within the next ten years. The water company is aiming to reduce its annual diesel consumption from 4 million litres to zero.
It has already invested in 17 electric vehicles and has nine EV charging points across its sites. In the long run this may prove to be a more efficient use of biogas than injecting it into the gas grid.
Equipment manufacturers serving the water industry — especially those that use diesel engines such as mobile pumping and drainage equipment — have been preparing for some time to make their products fit for the latest round of emissions regulations.
The regulations are categorised based on the engine power rating and ignition type, with each category given limits for the output of carbon monoxide, nitrogen oxides and particulate matter. These standards are applicable to diesel engines from 0 to 56 kW and to all types of engines above 56 kW, therefore bringing in much more stringent regulations for a wider scope of engines.
One of the challenges facing the manufacturing industry will be to build equipment that is the same size and weight and, perhaps most importantly, price as their existing equipment. Engine size and weight will increase with the requirement to fit engines with selective catalytic reduction technology and diesel particulate filters.
For contractors this may impact on the size of vehicle they need to transport equipment and the volume of fuel they use on a daily basis. Engine emissions compliance can also be achieved by retrofitting engines with approved abatement technology. The retrofitting of exhaust post-treatment devices is a common procedure for heavy-duty off-road engines, such as generators or diggers, but generally not possible for compact machines used for tasks such as drain jetting.
The regulations include a transition scheme that takes into account the time difference between the date of engine manufacture and the time it is on the market before being sold. This means contractors may be able to purchase existing equipment for a limited period after the regulations come into effect, though the ongoing spike in demand will probably lead to limited availability.
Drain and sewer cleaning equipment manufacturer Rioned has spent years preparing for the new EU regulations and last year introduced the fully compliant ProfiJet T4 with a v48kW diesel engine. The company also produce machinery fitted with petrol engines including the CityJet Petrol that is available with a 37kW petrol engine with a catalyst. In the build-up to Rioned plan to unveil a range newly adapted equipment for the European market. The machinery needs to be re-designed.

Air Quality and the MCPD: Something in the Air
In recent years it would seem that most technology advances have taken place on two-stroke engines. In part this is due to the fact that marine two-strokes are very specialised engines with few if any counterparts in other industries and rapid change has been needed to ensure that the most popular engine type for medium to large vessels can remain viable in an increasingly regulated environment. With at least 25 different manufacturers plus a number of licensees, the four-stroke market is much more competitive than the two-stroke market. That could make survival for some makers difficult, but four-stroke engines are also used much more extensively for non-marine applications.SEE VIDEO BY TOPIC: Working of Diesel Power Plant

32 Common Red Diesel Fuel Questions & Answers
The leasing and set up costs included the cost of diesel fuel to run them. The nine turbines are located at two different sites in Adelaide, one of them being the now defunct Holden car making facility in the northern suburbs. He said chief executives of public sector agencies were being asked to find cost savings but he promised there would be no job cuts among frontline staff among nurses, teachers, firefighters or police. It was the last state budget before the next state election in March, where Nick Xenophon is expected to have a major influence. Opinion polls show Mr Xenophon is very popular with the electorate and is outpolling the major parties so far, even though the business community is nervous about the potential of an unstable government. Mr Koutsantonis said the public was interested in Mr Xenophon because he was a fresh face back in the state political arena. Mr Koutsantonis said Mr Xenophon tended to side with the conservatives in many of his voting decisions. The Macquarie entity and Canada's Public Sector Pension Investment Board took over the processing of transactions for the next 40 years, and were also given the right to commercialise some data. But the absence of the bank tax meant that projected surpluses for the next four years were all trimmed by various amounts. The government has also lifted a tax on foreign property buyers from 4 per cent to 7 per cent.
Diesel generators cost $339m in SA power fix
Diesel is a fuel that has had a mixed history, with varying levels of take-up by consumers around the world. In the world of transport, diesel engines have offered better fuel economy and torque than comparable gasoline engines. Particularly popular in Europe, diesel established a strong consumer base in both small commuter cars as well as heavy vehicles such as trucks and buses. Diesel is a hydrocarbon fuel with several advantages over gasoline. Its lack of volatility makes it workable to use in a compression-ignition mode, and diesel engines can be run with lean fuel-air ratios. It also has a higher volumetric energy density than gasoline, and thanks to low volatility, diesel engines can run at significantly higher compression ratios without risking detonation. Unfortunately, diesel also comes with its fair share of drawbacks.
