10% Renewables Policy

Posted by: Adrian Slatcher | Comments Comments Off

Oldham Council has a policy which states that renewable energy generation systems must be built in to new developments of a certain size (10 house units and non domestic 1000m2). These developments must have 10% or more of their energy from on site renewable resources. Oldham Council is one of the first local authorities in the country, and the first in Greater Manchester to have such a policy.

The location of New Cumnock is with an aged mining village near to the border of Ayrshire and Dumfries & Galloway. Due to the diminishing of mining through out the years and the reduction of the textile industry, much of the village has suffered.

The outdoor swimming pool that was built in the 1960s was closed down by the council of East Ayrshire an was taken over by the community under the banner of New Cumnock Environmental Volunteers (NERV). This group was set up to improve the environment and leisure activities in the area. The swimming pool was has had substantial improvements which include new showers, changing facilities and tiling of the pool and the relating surroundings.

The New Housing Association is a charitable housing organization which has been developing housing since 1991. The New Housing Association develops and manages housing for rent, mainly in the Glasgow area. In addition to normal housing, Thenew also develop special needs housing. This is in partnership with specialist care providers.

Kirkhaven Hostel is a newly developed hostel with partnership of Crossreach. Crossreach is a local care agency within Scotland. The hostel will offer 24 hour acre for 14 adults with issues relating to alcohol. The building possesses under floor heating. The heat is generated by solar panels connected to a closed loop geothermal system.

Deighton Centre Wind Turbines

Posted by: Adrian Slatcher | Comments Comments Off

This case study provides information about the two 15 kWp wind turbines installed on the edge of the playing fields adjacent to the Deighton Centre in Huddersfield.
The turbines were installed in May 2006 and generate electricity, without emissions of carbon dioxide, for the Deighton Centre. Any remaining energy generated is exported to the National Grid. The wind turbines are located more than 110m away from the Centre and the nearest residential dwelling is more than 100m away down steep banking. At low wind speeds the difference between background noise levels and noise from the turbines is zero at 60m away from the turbines. At high wind speeds the noise difference is zero at 20m.
Flicker or shadow effect can be caused when turning turbine blades cast a moving shadow and cause a flickering effect. This is not a common effect and is dependant on many factors. The distance between the turbines and the building is sufficient for flicker effect not to be an issue.

Community-owned wind turbine in the Dulas Valley

Posted by: Adrian Slatcher | Comments Comments Off

In the month of April 2003, the UK’s first community owned and developed wind turbine was switched on in the Dulas Valley in Wales. The residents of Pant pert hog village very much enjoyed the idea of a community owned wind turbine. This led to the installation of the 75kW second-hand Vestas wind turbine. The wind turbine is located on the hill above the Centre for Alternative Technology (CAT).

CIS Tower Manchester

Posted by: Adrian Slatcher | Comments Comments Off

In 2005 the CIS Tower in Manchester was transformed into the largest vertical solar array in Europe. The unique £5.5 million project on what is the tallest office building in the UK outside London, began in 2004 when old mosaic tiles began to fail and started falling from the building. Thinking of an environmentally sustainable, long-term solution was difficult, since traditional cladding would have had a negative ecological impact. Therefore, it was proposed to clad the structure in photovoltaic cells, which reached peak capacity in 2006 and now feed directly into the National Grid.

The municipality of Thessaloniki and the Region of Central Macedonia commissioned the Centre for Renewable Energy Sources of Greece (CRES) to study the possibilities of integrating Renewable Energy Technologies to the former Municipal Abattoir building, which will be converted into an athletic and cultural centre.
The early 20th cent. existing building, which is protected by the Ministry of Culture, will be restored and reused for cultural activities. A new building will be constructed near it, in order to house practice halls for weight-lifting, fencing, target-shooting and dancing. Its southern façade supports an inclined surface for the integration of photovoltaics, which are expected to cover a significant part of the energy demands of the building.
CRES is contracted to investigate the following for the new building:-
– Measurements of the expected thermal performance of the building;
– Natural and artificial lighting;
– Integration of Photovoltaics;
– Heating and cooling systems using geothermal heat pumps;

Circle of Wind – Manchester Wind Energy Project

Posted by: Adrian Slatcher | Comments Comments Off

Despite renewables commitments, and an abundance of potential wind energy, the UK only generates 0.5% of its electricity requirements using wind power. Wind energy could cause a significant impact on the UK’s efforts to reduce carbon emissions and meet domestic and European targets. However, action at the local level is needed if the target is to be met. The Circle of Wind project is working with a number of Local Authorities across the city-region to demonstrate that wind turbines can be successfully placed in urban and industrial areas. Feasibility studies are being carried out on potential sites across the city-region. The project aims to be a symbol of Manchester’s commitment to renewable energy and a demonstration that there are local benefits to community ownership of such schemes.

The HYDROSOL research team has developed an innovative, solar reactor, for the production of hydrogen from water vapour, resembling the familiar monolithic catalytic converter of automobiles. The ceramic multi-channelled monolith is heated by asborbing solar radiation and is coated with nano structured materials, which split water vapour passing through the reactor, by trapping its oxygen and leaving in the effluent gas stream pure hydrogen as a product. In a next step, the oxygen trapping material is solar-aided regenerated (i.e. releases the oxygen absorbed) and hence a cyclic operation is established on a closed reactor system. The uniqueness of the HYDROSOL approach is based on the combination of highly active nano particle materials (synthesised by novel routes based on aerosol processes, combustion techniques and reactions under controlled oxygen pressure) and their incorporation as coatings on special refractory ceramic monolithic reactors with high capacity for solar heat absorption.

The severe environmental problems and the continuous increase of oil prices have accelerated the development of applications exploiting Renewable Energy Sources (RES) for electrical energy production. However, the amount of energy produced is characterised by significant fluctuations, mostly because of its dependence on meteorological conditions, which makes it important to develop solutions for short- and long-term energy storage to be later utilised.
The system developed by the HYRES project utilises the time-varying surplus of energy to produce hydrogen which is stored and further utilised in Fuel Cells to produce electrical energy, as a means to compensate for lower RES energy. The system is developed for stand-alone applications of small energy consumers in remote areas.
The system will consist of:
– A 5kWp PV array and 3kWp wind turbines for electrical energy production.
– An electrolyser for hydrogen production, rated at 4kW.
– A hydrogen storage system (compressed hydrogen).
– A 4kW PEM fuel cell.
– Lead acid batteries for short-term storage, rated 3.000Ah at 48V.
– A gen-set for emergency conditions.
– Power electronics converters for power conditioning.
– Control hardware
