Read More"Carbon footprints of various sources of heat – biomass combustion and CHPDH comes out lowest " – William Orchard.
The analysis indicates that burning biomass in large scale CHP has significant benefits compared to Anaerobic digestion of biomass and then burning the gas in CHP or in boilers. The table follows the convention of treating the growing of biomass and the CO2 it absorbs as one process and then the use of biomass as […]
Read MoreNational Grid comes out for Biogas in a big way – 50% of UK gas demand
Acording 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 […]

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 […]

Clean Air Power Limited are converting UU’s diesel trucks at Davyhulme the sewage treatment works serving the large Northern City of Manchester, famous for its football teams, to run on dual fuel diesel-biomethane. The basic idea has been around for years, essentially methane is fed into the inlet of an ordinary diesel engine, where the […]

UK 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.

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. Nigeria is forecasting LNG production of around 60 million tones per annum by 2012, bringing in around $60 billion of income – not a bad return for what was flared off as a waste product until 1999. High natural gas prices in the US are also bringing forward huge resources of ‘tight’ natural gas that are now economic to produce. Such gas needs more wells than normal gas and so requires the higher gas prices we have now – historically low natural gas prices in the US have acted to leave the ‘tight gas’ in the ground but it is now economic to bring it to market.

Desert Rose – Fresh Water & Forest Cover
Desert Rose – Fresh Water & Forest Cover
By Dr Richard Lawson
2008 Conference Paper Synopsis: Desert Rose is a conceptual approach to using two resources – sunlight and seawater – that coastal tropical areas have in abundance to supply two resources that are in short supply and dwindling – fresh water and forest cover. It suggests that once past a critical point, the growth in forest and water tend to become a self-propagating system. Energy costings relating to developing this concept are addressed.
