Scientist wants to use CO2 to generate clean electricity


Today solar and wind power becomes more and more commonplace, but there is still a basic problem that comes with these solutions, how do you store the energy produced to be used at a later time? Scientists at GE Global Research have decided to try and solve this problem by storing some of the heat generated by thermal solar power plants in carbon dioxide.

These power plants concentrate solar rays with vast fields of mirrors and use the heat to generate steam that spins a turbine. The carbon dioxide stored under ground is cooled to a solid dry ice state using excess grid power, and when extra electricity is needed, for instance during night, the heated salt then can be used to warm up the solid CO2 to a “supercritical” state between a gas and solid.

Royal Philips have just introduced a new instant fit LED replacement tube intended to greatly reduces the cost of replacing existing fluorescent tube lighting compared to other energy efficient LED technology alternatives.

The commercial sector has for a long time been better than the residential sector at both reducing cost, and energy use, by dropping incandescent for fluorescent lighting. However, lighting a commercial building like a factory or a large store still requires vast quantities of power, and changing from fluorescent lighting to a LED based solution has until now required a large investment that will take a long time to recoup.

For just this reason Philips has developed a new InstantFit LED lamp that fits in to existing lighting fixtures, and that requires no rewiring. LED tube lamps use up to 50 percent less energy compared with common linear fluorescent tube lighting and also require less maintenance due to their long lifetime.

Back in September 2011, Mayor of London Boris Johnson called for a zero-emission taxi in London by the end of the decade. Today Nissan just unveiled the Nissan NV200 London Taxi, a vehicle that might just make that target achievable. The NV200 London Taxi will offer significantly reduced CO2 outputs compared to current taxi models. Something that should make the Mayor smile as it shares the same focus as his Air Quality strategy for London.

The NV200 will come in two version. One features a 1.5 dCi 89 HP EuroV diesel engine and a 6-speed manual drivetrain, that achieves 53.3 Miles per Gallon on a combined cycle. This achieves almost a 50% fuel saving compared to the, until now most efficient TX4, with it’s combined cycle figure of 35.3 Miles per Gallon. An all-electric e-NV200 concept is also set to undergo trials in the Capital.

With increased demands for individual mobility, and with more people moving in to the big cities, the need for an efficient, but environmentally friendly urban transportation solution is needed. You could of course buy a bicycle, a solution that has been available even longer then cars. A regular bike will take you where you want to go in your local area at zero carbon emission, and at the same time it gives you exercise. Yet today a lot of people still have a tendency to take the car, even for going to the local shop a 10 min walking distance down the road.

BMW Motorrad has seen the signs of the times and is expanding its business activities to include the facet of urban mobility. The first stage of development was an e-scooter concept vehicle presented at the BMW Motorrad Innovation Day 2011. Shortly after this, the corresponding design study of an e-scooter saw its premiere, the BMW Concept e. The latter embodies the aesthetic vision of an electrically powered scooter. On July 27th 2012 in London, BMW Motorrad presented the highly promising third stage of development. The near-production ready prototype of an e-scooter that might soon become part of everyday road traffic in cities throughout the world, the BMW C evolution.

General Electric recently demonstrated a breakthrough water treatment method, they call AquaSel non-thermal brine concentrator (NTBC) technology, that virtually eliminates any water losses in ingredient water production. At a major global beverage company in Asia, GE recently conducted a pilot study were they achieved a near-zero liquid discharge (ZLD), and reduced water costs, without the normal energy expenses associated with a thermal evaporation system.

With today’s technology, bottling companies typically use 75 to 85 % of the incoming water for bottled water and the variety of soft drinks they produce, and the rest is discharged as a waste stream. Using GE’s AquaSel technology, these companies could safely treat and reuse the water, to achieve 99+ percent recovery in their plants.

Scania has been awarded the ‘Energy and Environmental Prize for 2012’ from the German motorist organisation Automobil Kraftfahrer-Schutz (KS), for their intelligent cruise control system, Scania Active Prediction. The system can deliver a fuel saving of up to 3% when driving on undulating stretches of road by using GPS to determine the vehicle’s position and to predict the topography of the road ahead.

At first look a reduction of 3% might not seem a lot, and for a car this might be true, but if you instead apply the percentages on a 40-tonne truck combination (tractor unit and semitrailer) running 180,000 km/year, a fuel saving of 3 percent would reduce fuel consumption by about 1,700 litres (almost 450 gallons) per year. This would be equivalent to an annual reduction in fuel costs of almost €2,300 (about $2,800), and even more important a reduction in carbon dioxide emissions of over 4 tonnes.
