A very significant admission by the US FERC chairman that the issue of integrating variable sources of power is not such a big issue

Wind Power and Reliability: The Roles of Baseload and Variable Resources Federal Energy Regulatory Commission (FERC) Chairman Jon Wellinghoff has stated that “baseload capacity is going to become an anachronism” and that no new nuclear or coal plants may ever be needed in the United States. Quote from Press Release: “1.  This fact sheet explains […]

Is Wind Power Reliable? Capacity Credit of Wind Energy

Is Wind Power Reliable   The following is a commentary on David Milborrow’s article in “New Power UK/Issue 1/February 2009”.   As David says, you would not design a thermal power generating system which did not have built in reserve. He has answered his comment about those letter writers being unconcerned (or unaware) that there […]

Article in IET queries role of wind power and balancing costs in the UK

David Millborrow is a Claverton participant…. Thanks to Hugh Sharman for forwarding this piece. This article from David Millborrow seems to pretty much demolish this article.. .. http://tx1.fcomet.com/~claverto/cms/download/316/ …………………………………. Quote ” Today, the UK is committed to European Union targets to deliver 35 per cent of electricity from renewables by 2020. Starting from a base of […]

Gas Turbines on the Isle of Man: A Case Study between the Manx Electricity Authority and Cranfield University. IDGTE paper at Cranfield, Thursday 19 March.

In the volatile energy market effective use of the available technological, energy and financial resources is now, more than ever, highly pursued. In a combined cycle power plant, gas turbines are the prime mover of power generation. Therefore, detailed understanding and monitoring of gas turbine performance, health condition and associated costs have a deep impact in the decision making process concerning the plant’s operational and maintenance strategy.

In this context, research collaboration between Manx Electricity Authority (MEA) and Cranfield University has been carried out since 2001 and a series of technologies and software have been and are still being developed at Cranfield University and some of them have been integrated into MEA Combined Cycle Gas Turbine Power Plant in Pulrose, Isle of Man. During this constructive and successful collaboration period, the University has been fortunate to acknowledge the industrial needs and make significant academic contributions through ongoing research projects jointly supported by both MEA and EPSRC. On the other hand, MEA has valued the complexity of asset management concerning the gas turbine and the combined cycle, therefore enhancing its trading and operational capabilities through the application of developed performance, diagnostic, trading and economic analysis software.

BBC newsitem: Rapid-charge/discharge modified lithium-ion batteries

   Interesting item claims scientists have developed “affordable”, rapid-charge / discharge modified lithium-ion batteries. This improvement might make a significant difference to the prospects for practical EVs / PHEVs, by extension to G2V for smoothing wind energy outputs.   http://news.bbc.co.uk/1/hi/sci/tech/7938001.stm

(IGCC) Integrated Gasification Combined Cycle for Carbon Capture & Storage

Abstract

This paper endeavours to give an objective account of the background to gasification based processes for power generation with carbon capture. Such processes are a development of IGCC plant designs in which coal or heavy fuel oil is first gasified and to produce a fuel gas for a CCGT unit. Although the IGCC concept does lend itself, very well, to high levels of carbon capture, and could lead the way to the hydrogen economy, it does create some important technical challenges. In particular, it restricts the type of gasifier that can be used to the high temperature entrained flow type. Furthermore, because the fuel gas that is produced in an IGCC consists of over 90% hydrogen, this will reduce the efficiency of the plant. Given that the hydrogen economy is some decades away, a more reasonable gasification-type option would be to produce natural gas from coal. This substitute natural gas could be used as a fuel gas in standard gas turbines (with no efficiency penalty) and can be used to supplement the UK and EU fast declining reserves of natural gas. The main drawback is that only about half as much carbon would be captured as in the IGCC “clean coal” systems currently being envisaged.

BBC talks about Dynamic Demand (smart fridges) and Smart Metering.

BBC programme “You and Yours” discussed the issues in a pretty comprehensive and well researched manner..  A representative from David Hirst’s (A Claverton Member)  RLTek company described how the frequency sensitive device, fitted to fridges, which are now being sold in UK can help the grid. Also talked to the Opposition spokesman on energy about Smart […]
