LATEST NEWS New report warns of massive amount of water used by traditional power plants to generate electricity A report published today by the European Wind Energy Association highlights the fact that that traditional power stations use vast amounts of water to generate power – and calls for this to be taken into account by Governments when they set energy and climate change policy. EWEA’s report “Saving Water with Wind power stations in Europe use 4.5 billion cubic meters of water a year, mainly for cooling purposes. This is equivalent to three Olympicsized swimming pools being consumed every minute, or the amount of water used by 82 million EU citizens annually. Energy production accounts for 44% of the EU’s total water use, way ahead of agriculture (24%), the public water supply (21%) and industry (11%). The study warns that such plants are contributing to Europe’s water scarcity, whereas wind energy uses hardly any water to generate clean electricity. EWEA is urging European Heads of Government meeting on 20th-21st March to take this into account when they formulate energy and climate change policies. RenewableUK’s Director of External is a very precious resource – water restrictions were imposed in the UK in the summer of 2012 in areas hit by wind energy is that it requires hardly any water to keep generating. This report is a timely reminder of the environmental impact of other technologies which use vast amounts of water for cooling. When Governments set energy policy, they should take this into account – it’s not just the carbon footprint that matters, but also the water swallowed up by these other thirsty generators”.

But the jobs and the UK-wide economic reboot won’t happen to the full unless Government policy is 100% supportive. “To make the most of our world-beating sector need certainty on policy, with Government standing four-square behind us to achieve growth at a brisk away, or other European countries will leap in and grab as many of the manufacturing opportunities as they can. “In particular, we’re hoping the Chancellor George Osborne will make his support clear in his Budget Speech next week. The industry is calling on him not to freeze the Carbon Price Floor, as that would send the wrong signal about the Government’s commitment to encouraging low-carbon generation. fossil fuels and make clean power more attractive should be promoted rather than scaled back”.
majority aren’t in favour of fracking.
47% within this age group are in favour of carbon capture and storage, and a mere 42% support fracking. The survey shows that younger people are generally more supportive of wind, and 51% were in favour of carbon capture and storage.

WESTERN PLAINS ENERGY (WPE) BIOGAS PROJECT
About Western Plains Energy (WPE) Western Plains Energy (WPE) is an ethanol production facility in Gove County, Kansas, USA. WPE started producing fuel grade ethanol as well as distiller’s dry and wet grains in 2004. The feedstock used by the plant to produce ethanol includes corn and milo. The original plant was a 30,000,000 gallon faceplate design which was increased to 40,000,000 gallons as part of an expansion in Currently, WPE produces approximately 2005. 50,000,000 gallons of denatured ethanol annually.
The Challenge
Himark worked closely with WPE to determine the technical and economic potential of the biogas plant and assess the energy potential of available waste streams. Himark developed plans, process diagrams, and business cases, and issued its licenced technology. During the engineering and construction stage, Himark worked with vendors to ensure proper design and implementation of the technology. Furthermore, Himark provided training and testing services to ensure the optimal operation of the facilities.
In the last several years, the US Environmental Protection Agency (EPA) has been updating renewable fuel standard regulations and some US states have been adopting a low carbon fuel standard, which has provided incentive to ethanol plants to replace natural gas or coal with biogas.
It is pertinent to note that Western Plains Energy received a USD 5 million grant from USDA Government for the construction of the biogas plant, after a two year vetting process of technologies of twenty four waste-to-energy solutions providers.
To command premium pricing for ethanol products, achieve savings in the form of D5 RINS and low energy bill, and ensure stable energy supply, WPE was on the lookout for a technology that could utilize locally available contaminated sand-laden cow manure (extremely dirty feedstock) to produce energy to power its ethanol operations.
Today Western Plains Energy (WPE) stands as an Advanced Biofuel producer and one of the largest biogas plants in world. It has an input capacity of 2800 tonnes a day of dry material and 1000 tonnes of wet material. The feedstock it uses includes cattle feedlot manure, ethanol plant waste, slaughter-house waste and municipal organics, which are rich in sand, dirt, rocks, plastic, and cellulose.
Himark BioGas Solution WPE went through a rigorous technology assessment process, and selected Himark’s patented IMUS™ technology for its reliability and success with contaminated feedstock.
WPE produces over 2,500 gigajoules (GJ) of heat a day, equivalent to 11 Megawatt (MW) of electricity capacity.

leading to increased maintenance costs and downtime. For this reason many engine manufacturers stipulate a maximum H S concentration in their warranties. One of the most common ways of reducing the H S concentration is to inject iron chloride into the digester slurry or feed substrate, converting the H S into iron sulphide particles. additional process control functions with dedicated pumps and storage vessels and therefore has associated on-going operational costs. James Hladkij, the AD Technician at the Cory Waste Management site in Westonsuper-Mare said:

and waste gas control treatment and use equipment, combined with Allison analysers, has enabled Cory Waste Management to protect its combined, heat and power (CHP) plant at minimal installation and operational cost. package the desulphurisation system
at the Cory site features the Allison Engineering AWITE Biogas analyser which is supplied with its own air compressor and uses a combination of PID and Fuzzy Logic control to automate the injection of small quantities of air (0.5 to 1%) into the gas stream within the digester. The oxygen converts the hydrogen sulphide (H S) to elemental sulphur and water, a process which is completely automatic and does not require any operator input and so eliminates additional operational and maintenance costs. The H S concentration in biogas from anaerobic digestion (AD) can be up to 2,000 to 3,000 ppm. When the biogas is burnt in a CHP plant to generate electricity the H S breaks down, producing a weak sulphuric acid that can cause corrosion within the engine,
We need to protect our CHP plant operations and maintaining H S concentration levels to less than 300 ppm is essential part of this process. achieve levels of less than 100 ppm and at minimal operational cost. From small agricultural sites to larger industrial AD plants, accurate and dependable online gas composition analysis is an essential part of this process and the Awite range provides a wide choice of options. The range comprises the Awi-Eco, a low cost, compact discontinuous analyser which provides 50 CH and CO measurements per day, with 4-20 mA output and USB connection. For more sophisticated monitoring and analysis requirements the Awi-Flex provides continuous measurement for CH, CO, HS, O and H. This system connection. Most importantly, it can and pressure inputs and undertake automated desulphurisation control. All Awite analysers use a rugged, touch screen industrial interface which allows easy access to recorded data, sensor parameters and system diagnostics. This ensures that all information is instantly available, remotely.

Industrial Effluent Solutions Kings Lynn, East Anglia Project: Supply and Installation of industrial effluent works Client: Tulip Foods H2OK were appointed by a large food processing company to undertake the replacement of an existing effluent treatment plant.
Within the system, dissolved air is pumped in at the bottom of the unit so that the effluent forms a light, airy mousse on the surface. This layer is removed and pumped to a sludge tank for removal and disposal by tanker. This process reduces the level of suspended solids strength and also the COD level which needs to be kept to a minimum in order to minimise the trade effluent consent charges.
H2OK’s works included the design, supply, installation and commissioning of an appropriate industrial effluent treatment plant, specially designed to cater for the type and volume of waste generated on site. The system reduces the strength of effluent from the site in order to reduce significantly, the waste disposal costs for the client. H2OK had successfully undertaken similar schemes for the client at a number of sites in the South West region, making H2OK an obvious choice for the site in East Anglia.
H2OK work with a company who is a market leader in effluent treatment who provide state of the art technology which operates with environmentally friendly organic chemicals that are bio-degradable. The equipment selected by our engineers included a balance tank, flocculation unit and a floatation system which is designed to remove solids from the effluent.
Installation of the equipment required careful planning. Space on site was limited, leaving little free space for new equipment and measures had to be put in place to ensure the existing plant could operate throughout the scheme.
The project was completed in a very short timeframe and we have continuous correspondence with the client to ensure the operation of the plant is at its optimum at all times.
