Breaking the waves for inventors
During the next two years, Danish wave power inventors can have their ideas tested at a new test basin in Nissum Bredning, Denmark. The Danish Energy Agency has granted DKK 2 million (where DKK is the Danish krone) to the construction and operation of this test facility, which aims to provide ordinary inventors with a quiet place where they can experiment and verify their ideas.

Several wave power devices with imaginative names such as Poseidon, WavePlane, Wave Plough, Wave Dragon, Wave Turbine and Backward Bent Duct Buoy have already received grants from the government. To date, 17 different ideas have been subsidised for model engineering, development and testing. A newly-founded 'Association for Wave Power' is in contact with 35 inventors, many of whom are awaiting confirmation of funding to start building and testing their models. The association has DKK 2 million of public money to subsidise these inventions.

This procedure appeals to the broad public, allowing ordinary inventors to come forward with their ideas. One or more of these ideas might prove to be the ideal way of exploiting wave power energy. It is also possible for inventors from abroad to have their ideas tested at the new facility.

Energy efficient, low emission MSW incineration
A planned 25% expansion of the municipal solid waste (MSW) incineration capacity at one of four feed lines and corresponding ovens at the Amagerforbrændingen CHP plant near Copenhagen will generate 40% more electricity and at the same time reduce current emission levels. The 25% increase corresponds to an additional 17,000 tonnes of MSW.

The total project will include the expansion and re-furbishment of all four lines, at a total cost of
DKK 180 million ­ of which 23% of the cost is to be dedicated to environmental improvements, 7% to removing NOx from flue gas and 17% for bottom slag improvements.

The CHP plant's current flue gas cleaning installations already remove more than 90% of acids, fly ash and heavy metals. The current cleaning facilities also remove dioxins from the plant's flue gas.

When the total project is completed, which is expected in the summer of 2001, the plant will have an incineration capacity of 395,000 tonnes of MSW and will supply heat and electricity to more than 100,000 households.

New Danish Centre for Urban Ecology
Urban Ecology is more than saving energy ­ it means conserving resources and creating links between house building and the environment. This has a wide range of aspects, such as aesthetics, behaviour patterns of the inhabitants and the right choice of building materials.

A new 'Danish Centre for Urban Ecology' located at Aarhus aims to channel the expertise of environmental-friendly construction methods into industry and to communicate a message of sustainable behaviour to the people who live and work in a certain urban area. The involvement of local inhabitants is just as important as technical development.

At present, the technical trend is towards increased use of simple design, as well as the use of materials with an extended lifespan and the ability to look good with age. Today, more than 50,000 building materials are available; many of these are excellent, but some are problematic and even harmful to people and the environment in the long term The Centre is currently arranging courses, organising networks and creating a database of best practice in sustainable building solutions and urban ecology projects.

Dutch wind technology for China
Planned for a site near Huhhot in Inner Mongolia, China, the Huitengxile Wind Farm will have a total of 21 MW installed capacity. The contract for delivery of 35 turbines was signed in September 1998, and will be carried out with support from a 'MILIEV' (Industry and Environment Programme of the Dutch Ministry of Foreign Affairs) grant and with Chinese funding. The project involves a total investment of some NLG 34 million (where NLG is the Dutch guilder).

NedWind ­ a subsidiary of NEG Micon ­ will be supplying the turbines, which will be produced in the Netherlands. The turbines are of the NEG Micon three-bladed NM600-150/43 type, with a capacity to 600 kW and a rotor diameter of 43 m. For the Huitengxile site, which has a wind regime of the IEC class I, the steel towers will have a hub height of 40 m. The nominal capacity of the stall-controlled, doubled-speed turbines will be reached at a wind speed of 14 m/s and will continue up to 25 m/s. It is expected that the project will be completed before the end of 1999.

Landfill gas expertise exported to Spain
Combined Landfill Projects Ltd (CLP), the largest independent landfill gas developer in the UK, has secured its first contract in Spain. The project, based at Conica-Montemarta landfill site near Seville, is to design, finance, install, operate and maintain the site, which has the potential to be one of the largest schemes in the country. So far, relatively few landfill gas projects have been developed in Spain.

In an agreement with Abonos Organicos Sevilla SA, owners and operators of the landfill and waste recycling facility at Conica-Montemarta, CLP will have exclusive rights to generate over 4 MW of electricity.

The first phase of the project, to be implemented during 1999, will generate 2 MW of electricity, with up to 900 kW of the output being used in the waste recycling plant. The balance of the electricity produced will be sold to the local electricity distribution system. Later phases of the project will add a further 2 MW of capacity, thus doubling the output of the project and enabling up to 12,000 Spanish households to benefit from renewable energy.

Financing secured for the world's largest straw-fired power station
Impax Capital Corporation Ltd has successfully arranged the financing of £60 million (where £ is the UK pound) for the construction of a 31 MW straw-fired power station near Ely, in Cambridgeshire, UK.

The Ely Power Station has been developed by Energy Power Resources Ltd, which is majority owned by Electra Fleming, the venture capital group. FLS miljø A/S, a subsidiary of the Danish conglomerate FLS Industries A/S, has been selected to design, build and operate the Power Station, which began construction in September 1998. The power station will consume around 200,000 tonnes of straw per year and generate sufficient electricity to supply around 65,000 homes. The electricity will be sold under a Non-Fossil Fuel Obligation (NFFO) contract from the start of operations until 2013, after which it will be sold at the available market rate.

Bayerische Hypo ­ und Vereinsbank AG and De National Investeringsbank NV are providing a £52 million senior debt facility for the two years of construction, which will be repaid over the first twelve years of operation. The equity is provided by Energy Power Resources Ltd and Cinergy Global Ely Inc in the form of ordinary and preference shares totalling £8 million. Cinergy Global Ely Inc, which will have a 30% stake in the project, is a subsidiary of Cinergy Corporation, of Cincinnati, Ohio.
