Scientists over the world have for long tinkered with the idea of generating clean electricity with the help of bacteria, which the world knows can transfer electricity into metals and minerals. Taking forward the research, a team of scientists at the University of East Anglia has found that marine bacteria called Shewanella Oneidensis, have proteins that can produce an electric current by simply touching the mineral surface.

While producing hydrogen by simply using solar energy and water seem to be the holy grail of clean energy, actually the process isn’t as simple as the one you might have tried out in your chemistry lab. Producing large quantities of hydrogen, while making use of minimum amount of electricity uses catalysts, which are usually, made using expensive and rare-earth metals, driving up the cost of hydrogen hence produced. As a solution, two chemistry professors from the University of Calgary have created a new method of water-splitting catalysts using abundant metals.
Virginia-based energy company, Dominion has teamed up with FuelCell Energy to develop the largest fuel cell power plant in North America. The environmentally friendly power plant will be built in Connecticut and will use a clean process to transform natural gas into electricity. Once operational, the plant will produce 14.9MW of clean power, enough to provide electricity to 15,000 urban homes.
While there is no dearth of engineers who are planning to build some of the fastest and the most energy efficient trains in the world, a team of researchers from University of Birmingham in UK are working to develop a hydrogen fuel cell powered train that is entirely zero emission. Though, the first iteration developed won’t win any awards on the design or the amenities onboard, it could definitely serve as a stepping stone for a greener future of public transportation.
While cleaning up our lawns on a sunny weekend, we often forget that conventional lawnmowers that are powered by gasoline engines produce not just noise, but a variety of greenhouse gases that pollute the environment. Moreover, gas-powered lawnmowers aren’t easy to start and their maintenance cost is also very high. Industrial designer Otto Polefko has come up with a concept lawnmower that solves all the above mentioned problems.
While the world is constantly on the hunt for clean and emission-free energy, hydrogen seems to be the perfect fuel. However, even after being the most abundant element in the universe, hydrogen doesn’t exist in its pure form on our planet. Most of it is found either in water or other chemicals, requiring a kind of extractor before we can use it to generate power. Conventionally extraction procedures highly depend on fossil fuels, which reduce the eco friendly credentials of hydrogen.
One thing common with all energy generating techniques, be it renewable or conventional, is that once the source of energy or fuel runs out the reaction stops and hence the power generation also ends. We know that the basic laws governing these reactions won’t allow the system to produce energy without fuel, however a new research by a team of material scientists at Harvard University have proved that energy can continue to flow even if the fuel runs out.
Gas powered vehicles are pollution-intensive, electric cars are slow and take hours to recharge, so one possible eco friendly solution for driving in the future is hydrogen fuel cells. However, like all upcoming technologies, hydrogen fuel cells too are marred with drawbacks such as high cost and lack of refueling infrastructure.
After operating its data centers and HQ with a 650KW solar array and a 500KW Bloom Energy’s fuel cell installation, eBay has escalated its green efforts by partnering once again with Bloom Energy to develop the largest fuel cell powered data center in the US. The new 6MW renewable data center will make it the country’s largest fuel cell installation.
