Stanford reported blue energy projects: mixing water and waste water recycling power battery

Scientists at Stanford university team announced a low-cost, durable blue energy research projects, published today in the paper describes a from seawater and freshwater hybrid renewable energy access to energy in the process of preparation of battery technology. Team says blue energy is & throughout; Untapped limitless reserve of renewable energy & other; 。

the team development of this kind of battery is without using film, mechanical parts, energy efficiency and make great progress in battery technology. The battery prototype has been put in the test, the scientists put battery materials in gradient field brine for energy efficiency test, exchange from the Palo Alto waters (per hour Fresh water) Wastewater treatment plant of wastewater collection, as well as from the Half Moon bay area to collect water mixed flushing.

after a 180 - cycle, cell materials with gradient salt paddy field in terms of collecting energy keep the effectiveness of 97%. The team says the technology can be used anywhere in the freshwater and saltwater mix, but wastewater treatment plants is a special practical case studies. Wastewater treatment is energy-intensive, accounts for about 3% of the total power load. Battery technology can help independent power wastewater treatment plants.

the team says, is mixed with water about 0 per cubic meter of water. 65 kilowatt-hours of energy, it is enough to power supply for ordinary family, about 30 minutes. Globally, is located in the coastal areas of the sewage treatment plant of theory of recoverable reserves of about 18000 megawatts, enough to meet the 1700 households a year's supply.

for the implementation of the central committee of the communist party of China under the State Council on further deepening the reform of electric power system of several opinions ( Found [2015] 9) File spirit, since November 2016, the National Development and Reform Commission, the National Energy Administration three nationwide pilot reform has carried out 320 increment distribution business. Pilot reform effectively stimulated the enthusiasm of the social capital investment increment distribution project, promote the development of the distribution network construction, in promoting the distribution network operating efficiency, improving quality of power supply service made a positive exploration, but some areas lack of pilot projects to promote, pilot project to start construction delays.

when sodium and chloride ions released from the battery electrodes to the solution, to produce energy, the electric current to flow from one electrode to another electrode. Waste water and seawater rapid exchange of electrode to absorb sodium and chloride ions and countercurrent current. Result is battery charging and discharging, no upfront investment in energy.
