Carbon tax to drive up fuel costs

HARRY MCGEE, Political Correspondent

The new carbon tax at a rate of €15 per tonne will result in increases of 4.2 cent in the price of petrol and almost 5c in the price of diesel from midnight tonight.

The Minister for Finance Brian Lenihan announced the measure in today’s Budget speech, saying it was designed to change behaviour to reduce greenhouse gas emissions.

“The most effective way to to put a price on carbon. This will encourage innovation by incentivising companies to bring low carbon products and services to the market,” he said.

The measure will yield a total of €250 million next year and some €330 million in a full year.

Notably, the Minister said that not all of the revenue would be ringfenced to encourage lower carbon emissions. He said some would be used to boost energy efficiency, some to support rural transport and some to alleviate fuel poverty.

He added that the tax “will also allow us to maintain or reduce payroll costs”, an indication that it will not be revenue neutral.

Some €50 million of the revenue will be used to fund measures for households at risk of fuel poverty to make their homes warmer.

The excise changes for oil, gas and kerosene will come into effect from tonight but price increases in coal, peat will not occur until May 2010.

The changes will lead to increase of an estimated 39 cent for a bale of peat briquettes and €1.79 for a 40kg bag of coal.

The latest study from the ESRI estimates the changes will cost households an average of between €2 and €3 per week, or up to €156 per year.

Evance R9000 Vs Proven WT6000

“The Evance R9000 is the latest variant of the long established 5kW small wind turbine from the UK manufacturer Iskra, recently re-branded as Evance.

The R9000 is the first turbine to be equipped with Reactive Pitch technology, a unique control concept developed and patented by Evance. Reactive Pitch guarantees that the blades will capture exactly the right amount of energy according to the wind speed and generator loading conditions.

At low to moderate wind speeds the Reactive Pitch mechanism captures the maximum energy possible from the wind by holding the blades with absolute precision at the maximum efficiency position.

At higher wind speeds, when the energy in the wind exceeds the maximum capacity of the generator, the R9000’s unique Reactive Pitch mechanism automatically pitches the blades. This regulates energy capture, rotor speed, and the loads experienced by the turbine structure. It will therefore capture the full 5kW power, and the reduction in stresses mean that the R9000 offers greater safety and survivability

The R9000 also has a patented high-efficiency generator which converts up to 96% of the energy captured from the wind into useful electricity. The generator is specifically designed for the R9000, and is integrated into the turbine’s rotor.

What all that means is that the Evance R9000 can capture more energy across the range of wind speeds, especially the lower and moderate speeds that are normally experienced on the majority of the mainland UK.
The combination of the advanced pitch control, which is much more effective than the Proven’s “coning” mechanism, and the more efficient generator enable the Evance R9000 to out perform the Proven WT6000 at lower to moderate wind speeds…”

Eco Evolution featured in the Irish Independent – hydro electric

  • Hydro electricity — Hydro electric generation — even on a small scale — can be a more cost-effective and, more importantly, predictable and consistent method of generating electricity on both a micro and commercial scale. If you are lucky enough to have a decent size stream running through your farm, it may certainly be worth looking at.

Co Wexford-based Eco Evolution (www.EcoEvolution.ie) is the agent in Ireland for the Landustrie range of Archimedean Screw hydro turbines supplied by Mann Power Consulting Ltd, the Archimedean Screw hydro turbine specialists in the UK.

Frank Gethings is the MD of the Ferns-based company, which specialises in the micro-generation technologies of wind turbines, Landustrie hydro turbines and solar PV systems. It also supplies and installs solar thermal systems, air-to-water heat pumps and mechanical ventilation with heat recovery (MVHR) systems.

The Archimedean Screw is old technology used as water pumps to lift water from one level to another. Landustrie manufactures two types of the Archimedean Screw, one for pumping water — as originally designed — and the other to generate electricity using the flow of water in the reverse direction, downwards to turn the screw and generate power.

Mr Gethings says: “The requirements for driving the screw are quite low, with a minimum head requirement of just 1m, up to a maximum of 10m. There is a minimum flow requirement of 100 litres/sec, which is the equivalent of a sizeable stream.”

These are said to have many advantages over the more traditional types of hydro turbines; the most important of these probably being the fact that they are fish friendly. Also, leaves and debris simply pass through the turbine with no fine screening required.

“They are also highly efficient across a large flow variation, with a hydraulic efficiency of 87pc and a water-to-wire efficiency of 77pc. They are suitable for small, domestic applications from 1kW up to larger commercial applications of 350kW.

“With each application we would have to do a feasibility study on each site and then the Archimedean hydro-electric plant would be custom-made to suit the site.” Small plants would generate as little as 1kW, while bigger plants could generate up to 350kW handling a water flow of up to 10,000 litres/sec.

“Old mills are ideal sites as the civil works are already in place and there is the potential to generate up to 15kW or so, depending on what’s there.”

Planning permission would be required for such an installation, and in the UK they have gone through all the processes to establish it as a fish-friendly design. Being site specific, it could be hard to estimate the price of installing such a facility, but MannPower Consulting has produced a chart in an effort to do just that.

Turning the screw on power

Turning age old technology on its head has started to allow one Irish company to produce electricity from flowing water.

Ferns based company Eco Evolution (www.EcoEvolution.ie) has become the first in the country to commercialise the Rehart range of Archimedean screw hydro turbines.

Frank Gethings, managing director of Eco Evolution, said “Archimedean screws were traditionally used as water pumps to lift water from one level to another. Archimedean screw hydro turbines work in reverse. Water from a river or stream flows down the screw causing it to rotate. The screw is coupled to a generator via a gearbox and hence power is generated.”

Like many green energy companies they supply wind turbines and solar panels but are finding huge interest in hydropower.

The system can range from 1kW up to 130kW on a single screw system. The first large system of 120kW is to be installed in Omagh, Co. Tyrone, to provide electricity for a leisure centre.

The Archimedean screw is suited to low head sites and can cater for heads of between one and 10 metres height and can take flow rates ranging from 100 to 10,000 litres per second.

For larger flows, two or more screws can be used.

Frank said there is scope for installing it on farms but having an existing mill or works will greatly reduce the cost. It costs €20,000 for the equipment for the 1kW system, but additional site works have to be carried out. Cost efficiency is an issue of scale. A 300kW system might cost €1,000 per kWh to install but a 1kW system might be €20,000.

The system allows debris to flow through and has also been proven to be fish friendly.

“… It is a point echoed across the industry. ”The general trend for energy costs will be an upward one and there is also the advent of carbon taxes to consider,” says Frank Gethings, Managing Director of Eco Evolution in Ferns, Co. Wexford. His company offers a wide range of renewable solutions, with wind electricity generating equipment to the fore and a new line in hydro electricity products just becoming available. Gone are the days when these technologies were the preserve of immense ESB projects: They can now be incorporated seamlessly into many business premises.

“Water has been used for energy generation for centuries, but Archimedean screw hydro turbines are relatively new to the market – they’re a 21st century application of an ancient technology,” says Gethings. “They are suitable for small domestic applications from 1kW up to larger applications of 350kW.” Both wind and hydro power work on simple principles: the rotor is turned by wind or water; a generator attached to the rotor then generates power that can be fed into the building’s power supply. Another renewable energy solution is solar power; a technology that has been around for years yet is only coming into affordable, mainstream usage now – particularly helping to reduce heating costs…”
