Green Fuels Introduces FuelMatic3 Processor for Small Biodiesel Producers

 

Sparks, NV, September, 2012 –(PR.com)– In an exciting development for the production of biodiesel, Green Fuels America Inc. has announced the release of the FuelMatic3 biodiesel processor which produces up to 750 gallons of biodiesel per day from used cooking oil, vegetable oil, animal fats, and tallow. This is now the smallest Green Fuels FuelMatic processor and is especially designed for closed loop production in a world increasingly concerned about climate change and reliance on the volatile price of unsustainable fossil fuels. read more

Could our most abundant resource – air – be the answer to South Africa’s energy problems?

UK Energy storage technology development company Highview Power Storage has built and tested the world’s first Liquid Air Energy Storage plant; and it could be the solution for South Africa’s energy problems.
Liquid Air Energy Storage (LAES) takes excess electricity from the grid at wrong times, such as during the night, and uses it to cool air until it liquefies at minus 196 degrees Celsius.
The liquid air can then be stored cheaply and safely until it is needed, when it is exposed to normal, ambient temperatures. The liquid immediately turns back into gas, expanding by 700 times, which is then used to turn a turbine and feed electricity back to the grid. The exhaust is cold air.
Critically, the system can be scaled to 100s of MWs of power and GWhs of storage, similar to medium scale pumped hydro, but without the requirement for mountains or large volumes of water.
Says Toby Peters, co-founder of Highview and COO, “Our pilot plant is fully operational on the UK grid and being tested for real-time peak shaving. It is delivering very high levels of performance reliability. The system is simple and uses mature components so is ready to be deployed at commercial scale. In fact our most exotic material is stainless steel.”
South Africa is regularly hit by power shortages as demand for electricity out-strips supply.
And with industry predicting power shortages to severely impact mining and steel production for several years to come, they are urgently looking for methods to protect security of supply.
Energy storage time shifts wrong time energy from intermittent renewables or must-run baseload plant to support times of peak demand. As Peters explains, “there is often enough electricity produced, but it is at the wrong time. This problem will only get worse as we deploy more intermittent renewables on our grids. Energy storage allows you to manage the overall available resource.
“While batteries are great at smaller scale and for fast response, the challenge for the industry has been to provide a large scale energy storage solution which does not have to rely on mountains and water.”
In addition to large scale energy storage, Highview’s technology can convert low-grade waste heat from co-located industrial processes to power and provide cooling for commercial use. read more
