Hi! Welcome to SRN’s new blog! We were keen to set up a platform for our network to share news, information about events, exciting research opportunities, and, most importantly, to reflect upon our sustainability experiences. We look forward to seeing this site develop and hearing your comments! 



  1. Thanks for writing the blog about your visit. Sounds like an interesting day. A few comments – as you mention, I find it surprising that much less wood is burnt than coal – surely this gives a lower power output? Can you summarise briefly sourcing of biofuel?
    Gaby, it’s good practice to spell out acronyms in full (Corporate Social Responsibility), first time at least – it’s really offputting for public or experts in different fields who aren’t familiar with the terms (or even use the same three letters for a different term…!)

    1. Hi Neil – many thanks for your comment and sorry for the delay in responding to you. It’s great to see people engaging with our content 🙂 This site is pretty new for us and we are just getting to grips with wordpress. I will look into your questions and come back to you with a response. Many thanks, Sarah

    Hi Neil. Thanks for reading and commenting on our blog. Yes, significantly less wood by volume is now burnt in the station than coal was two or three years ago. And you’re right that it does have a lower power output as a result. The average energy content by volume of wood pellets (which Ironbridge uses) is roughly half as much as coal (click on the link I’ve copied in below to compare the energy contents of a range of fuels). The station’s total power output when coal was used was 12,00MW whilst it is now 600MW. I think the reason E.On are happy producing a lower power output is that they are using the station as an experiment about which to learn about making electricity using biomass at larger scales. With regards to your question about the sourcing of biofuel, E.On imports all of the wood it uses at Ironbridge from North America (I think mostly, if not all, from Canada). We were told that many of the forests from which the pellets are coming from are being killed by the North American pine beetle. There are many interesting questions about where wood pellets will come from as biomass becomes more popular to produce electricity at increasingly larger scales.

    Here’s a link to the Biomass Energy Centre’s website where it lists the energy content of a variety of fuels: http://www.biomassenergycentre.org.uk/portal/page?_pageid=75,20041&_dad=portal&_schema=PORTAL.

  3. Many thanks for your informative comments Jeremy! 🙂
