Almost new gas engine built to operate on biogas generated from a gasification process from woodchip. The project is for The Highland Council in Wick who are carrying out an assessment of possible options for heat supply.
The engine specification is as follows:
- Engine model Jenbacher JMS 620 GS-S.L. (1.5MWe)
- Gas analysis: 15-20% H2; 3%CH4;15-20% CO; 10% CO2; 40-50% N2
- 43 starts
- Generated 6.4MWh
- Operated for 13 hours

National Grid comes out for Biogas in a big way – 50% of UK gas demand
Posted by: | CommentsAcording to National Grid “Renewable gas has the potential to make a significant contribution to the UK’s renewable energy and carbon reduction targets for 2020. And in the longer term, with the right government policies in place, renewable gas could meet up to 50% of UK residential gas demand. Produced mainly via a process of anaerobic digestion (AD) or thermal gasification of the UK’s biodegradeable waste, renewable gas represents a readily implementable solution for delivering renewable heat to homes in the UK.
Renewable gas can also deliver greater security of energy supply for the country as well as a solution for waste management as UK landfill capacity declines. In terms of the cost to the UK of delivering renewable gas, it is estimated that the marginal cost (i.e. that over and above the cost of the waste infrastructure which must be built anyway in the UK to deal with reducing landfill capacity) would be in the region of £10bn. This cost compares well with the likely cost of delivering other large scale renewables such as wind.

This press release is basically saying the UK is at risk of not achieving its Biodegradable Municipal Waste (BMW) landfill diversion target for 2013. This means that energy from waste plants (using anaerobic digestion) are too slow and difficult to procure even with government support for the PFI credits and with the risk of massive fines from the EU to spur local authorities into action. A bit depressing.

Biomethane vehicles open up green driving
Posted by: | CommentsUK business can now take advantage of the first mass scale second generation biofuel to be produced from waste. This is as a result of the launch in the UK of 3 brand new vehicles that have been developed by Volkswagen and Mercedes Benz to run on 100% renewable methane (biomethane)
The Volkswagen Caddy Ecofuel is ideal for companies who operate small white vans or far airport taxis who need 7 seats. The Sprinter NGT is the perfect large van, ideal for supermarkets and with thousands of applications. The Econic articulated truck is ideal for deliveries into cities and between distribution centres. All these vehicles have low environmental impact in terms of noise, NOX and particulates but it is their carbon neutrality when fuelled on biomethane that is transformational.
London aims for 25 anaerobic digesters which will provide 25 sources for biomethane for these vehicles. By making the renewable methane were waste is processed there is a very significant ‘well to wheels’ benefit – avoiding all the emissions associated with producing oil and refining it to diesel and the need to move fuel by road.
A number of major supermarkets are developing AD facilities to reduce their carbon footprint and moving their waste and their goods in vehicles fuelled with biomethane is a compelling proposition. No other combination of fuel and vehicle can come close to the carbon neutrality offered in these OEM produced and highly reliable vehicles with range for a days work and the ability to be refueled within a matter of minutes.
A clear and deliverable path to a sustainable future has arrived in the UK.

Bio-methane fuelled vehicles – John Baldwin CNG Services
Posted by: | CommentsClaverton Conference: 24th Nov 08
(*Also bio-methane or bio methane)
By John Baldwin, MD, CNG Services Ltd
Year 2008 may well be recognised as a turning point in the journey away from fossil fuels and this has major implications for the waste management industry. The increase in oil price to $140/bbl is the market signaling that, to use the words of Shell CEO van der Veer, ‘easy oil’ is running out. The large oil fields that have supplied the world with oil are starting to decline and new resources, such as oil sands in Canada, have much higher levels of CO2 emissions associated with their extraction.
At the same time, countries like Nigeria are capturing and liquefying the natural gas (to make LNG) that is a by product of oil production. Read More→
