The Benefits of an Archimedean Screw Hydropower Turbine

Energy generated from flowing water resources gives the highest efficiency rating of all sustainable energy sources!

The Archimedean Screw hydropower turbine is a new application of an ancient technology. For thousands of years the screw was used to pump water up from rivers or streams to irrigate farm land. Now, using the same system in reverse the Archimedean Screw is being used to harness the power of the water to generate hydroelectricity. Hydropower installations generate renewable energy from flowing water resources. This could be from a lake, river, stream or from old mill sites.

Archimedean Screw turbines offer a hydropower solution that is:

  • Commercially attractive & cost effective
  • Practical & efficient
  • Fish-friendly
  • Easy implementation in existing situations (no civil constuction work)
  • Insensitive to clogging
  • Low maintenance costs
  • Improvement of water quality
  • Self regulating to changing water flow
  • Long life time
  • Scaleable & bespoke

This technology lets you harness the power of the water that flows over or through your land. Once your turbine has been commissioned and connected to the grid you’ll be generating hydro-electric power 24 hours a day, seven days a week. Whether the power is for your own property, to sell back to the grid or a combination of both, the Archimedean Screw will likely pay for itself several times over in the course of its operational lifetime (depending on the feed-in tariffs available) . And what’s more these turbines can be scaled to suit all needs – from small domestic applications to huge industrial installations.

If you’re not sure whether your site is suitable for an Archimedean Screw we’ve put together a checklist of requirements for your reference. Archimedean Screw turbines offer a uniquely flexible hydropower solution that can be installed at sites with a broad range of topographical features. But there are some fundamental requirements your land will need if a project can go ahead.

The basic requirements required for an Archimedean Screw hydro turbine are:

  • A water source with a drop of at least 1.5 metres
  • Access rights to that water source
  • A grid hook-up point less than 500 metres from the water source – unless the Screw is being used for ‘off grid’ generation only.

If your site satisfies these criteria then there’s every chance you will be able to harness the power of the waterway to generate hydroelectricity. And Eco Evolution will be delighted to pilot your scheme all the way through to delivery.

If you’re still not sure whether your site is right for an Archimedean Screw turbine, get in touch and we will be happy to discuss the specifications and requirements in greater depth.

A Week of Celebrations and Awards for Eco Evolution!

What a week of celebrations it has been here at Eco Evolution!

The week began with a trip to Salerno to celebrate our Silver wedding anniversary. Hard to believe its been 25 years since we tied the knot!  The weather, scenery, locally grown and sourced foods and wines were just amazing. Definitely a return trip on the cards in the not too distant future 🙂 On Thursday night while we were enjoying our last night in Salerno I received a message telling me that I had won an award at the Blog Awards Ireland.

Public sector award pic4

On Friday we were presented with the Public Sector Excellence in Business Award for our contribution to the renewable energy sector in Ireland. Eco Evolution are hydro design specialists and offer advice and consultancy services to the public sector. The public sector is an important sector for us as it is through public projects that showcase these renewable technologies that public awareness and interest is created and increased. By supporting and implementing smaller scale renewable energy projects around the country the Public Sector can also help to educate the public more about these technologies and therefore possibly develop public acceptance and alleviate public concern about larger developments. The Public Sector needs to lead by example so it is important that they are seen to embrace these renewable technologies to help combat the effects of climate change and to help meet our 2020 targets.

Clean, green hydropower at Gara Bridge, Devon

The Archimedean Screw hydropower turbine is a new application of an ancient technology. For thousands of years the screw was used to pump water up from rivers or streams to irrigate farm land. Now, using the same system in reverse the Archimedean Screw is being used to harness the power of the water to generate hydroelectricity. This technology lets you harness the power of the water that flows over or through your land. Once it has been hooked-up your turbine will generate hydro-electric power 24 hours a day, seven days a week.

Whether the power is for your own property, to sell back to the grid or a combination of both, the Archimedean Screw will likely pay for itself several times over in the course of its operational lifetime. And what’s more these turbines can be scaled to suit all needs – from small domestic applications like the Gara Bridge scheme or to huge industrial installations like the hydropower project at Shane’s Castle. The hydro project at Shane’s Castle was the first of its kind in Northern Ireland and rated at 214 kilowatts it is the largest single Archimedean Screw generator ever manufactured.

hydro 5 (800x600)The hydropower scheme at Gara Bridge was developed to provide a renewable source of power to a private dwelling with any excess sold to the National Grid. The maximum output of this particular project is 15kW. The enclosed compact design which is suitable for smaller hydropower projects was the preferred design of screw for this particular site and the design also helped to minimise the installation cost.

Closed Compact –  Key Benefits:

  • Screw + trough + gearbox + generator are all assembled into a single unit at the factory.
  • Civil works on site reduced to a minimum.
  • Installation time considerably reduced (approx 3-4 hours)

Archimedean Screw turbines offer a uniquely flexible hydropower solution that can be installed at sites with a broad range of topographical features. But there are some fundamental requirements your land will need if a project can go ahead. If you’re not sure whether your site is suitable for an Archimedean Screw we’ve put together a checklist of requirements for your reference.

Naturally we will conduct a detailed feasibility study on your behalf but there are a few key features whose presence will determine the location’s viability for a Screw.

The basic requirements to host a screw are:

  • A water source with a drop of at least 1.5 metres
  • Access rights to that water source
  • A grid hook-up point less than 500 metres from the water source – unless the Screw is being used for ‘off grid’ generation only.

If your site satisfies these criteria then there’s every chance you will be able to harness the power of the waterway to generate hydroelectricity.

Renewable Energy Support Scheme – Public Consultation 2015

Update! The department of Communications, Energy and Natural Resources have extended the public consultation until 18 September 2015.

 

Two public consultation documents, published by Minister for Energy Alex White on Friday 31st July 2015 seek views on the renewable energy technologies that currently receive financial support from the State, and whether the Government should broaden the range of technologies it supports. One consultation focuses on renewable electricity technologies, while the other focusses on renewable heat systems.
The future of energy is in your hands!

The future of energy is in your hands!

The consultation on renewable electricity supports says that, while wind energy will continue to make an important contribution to meeting Ireland’s renewable energy targets, it should be complemented by other technologies to meet the country’s renewable energy ambitions. It says these could include bioenergy, solar, offshore wind, wave and tidal technologies if they are both technically feasible and cost effective, and says the consultation will help determine whether supports are necessary to develop these technologies.
The consultation will also explore the potential and value of providing supports to micro-generation and smaller community-based projects.
The Renewable Heat Incentive consultation document proposes a renewable heat incentive (RHI) to encourage larger industrial and commercial heat users to switch to systems that produce heat from renewable sources, including biomass. It will inform an assessment of the feasibility of various technologies deployed to produce heat from renewables and tariffs “at a level that represents the most cost effective transition to the levels of renewable heat required.”
The consultations will help determine the criteria for financial support schemes to replace existing programmes, including the REFIT schemes, which expire at the end of this year. They both emphasise the importance of citizen and stakeholder engagement in the development of renewable energy policy and infrastructure.

Renewable Energy Support Scheme – Public Consultation 2015

 Minister White said: “Encouraging the use of renewable electricity and heat sources will help us meet ambitious targets to reduce carbon emissions and tackle global warming. The energy White Paper, which I will publish in October, will set us on a path to transform Ireland’s energy production and consumption patterns so that, by 2050, our system will be largely decarbonised. One objective is to develop and broaden the range of renewable energy technologies at our disposal, which will also drive innovation and create green jobs.
“Our energy transition must respect citizens, who recognise the need to stop global warming, but who may also be concerned about the impact of energy technology and infrastructure on their communities. These consultations give everyone the opportunity to express their views on the renewable electricity and heat technologies that Government could support, before any decisions are made.”
The 2009 EU Renewable Energy Directive set Ireland a legally binding target of meeting 16% of its energy requirements from renewable sources by 2020. Ireland is committed to meeting 40% of electricity demand from renewable sources, as well as 12% of heat demand and 10% of transport fuel. Last October, the European Council reached political agreement on a target of a 40% reduction in European greenhouse gas emissions by 2030. The agreement committed the EU as a whole to increase the proportion of energy it gets from renewable sources to 27%.
The consultation will remain open until 17:30 Friday 11th September.
