There are currently 71 waste to energy (WTE) plants in the United States. WTE plants only account for 0.4% of total electricity generation, although there is great potential to increase this percentage in the future.
Seattle is among 17 major North American cities whose "2030 District" is driving high-efficiency district energy systems to share and exchange energy and heat between building partners - saving energy, money and maintenance costs, and providing more reliable power.
University of Cambridge via Biomass Magazine: Â Dr Moritz Kuehnel, from the Department of Chemistry at the University of Cambridge, joint lead author on a new research paper published in Nature Energy, says:
"Lignocellulose is nature's equivalent to armoured concrete. It consists of strong, highly crystalline cellulose fibres, that are interwoven with lignin and hemicellulose which act as a glue. This rigid structure has evolved to give plants and trees mechanical stability and protect them from degradation, and makes chemical utilisation of lignocellulose so challenging."
The new technology relies on a simple photocatalytic conversion process. Catalytic nanoparticles are added to alkaline water in which the biomass is suspended. This is then placed in front of a light in the lab which mimics solar light. The solution is ideal for absorbing this light and converting the biomass into gaseous hydrogen which can then be collected from the headspace. The hydrogen is free of fuel-cell inhibitors, such as carbon monoxide, which allows it to be used for power. Â Full Article:

The High Technology Development Corporations (HTDC) Hawaii Center for Advanced Transportation Technologies (HCATT) is sponsoring a demonstration of a $6.8 million renewable and clean, waste to energy generating system at Joint Base Pearl Harbor-Hickam (JBPHH), on the campus of the Hawaii Air National Guard (HIANG).
Inventing Simple® isn't just a slogan to us, it's a way of life. Using simple plug-and-play ideology, we revolutionized solar installations in 2003 with our Interconnect Systemâ„¢. Our harnessing system is now the gold standard EPC's use around the world. By using simple ideas, we are making solar energy a more affordable and clean power source for future generations.
