Innovative Engineering in Solar Relays

As the demand for higher kVA capacities of solar inverters keeps expanding, higher switching currents need to be accommodated by relays used in these applications.

Super Cathode Battery Technology

This Q&A will focus on the incorporation of BioSolar Super Cathode technology with lithium-ion batteries - and how your technology can achieve significantly higher capacity with costs below $100/kWh, which is less than half of today's lowest cost lithium-ion batteries.

German battery maker launches scheme to share solar power

Reporting by Vera Eckert for Reuters:  German battery maker Sonnenbatterie has launched a scheme to connect households with solar panels and other consumers, aiming to better distribute surpluses of the renewable energy and help members to become more independent of conventional suppliers. The start-up company hopes the scheme, called "sonnenCommunity", will boost demand for its batteries which store solar power, allowing owners to use the clean energy even when weather conditions are not favourable. SonnenCommunity takes the storage idea a step further, allowing solar power to be shared among its members. Sonnenbatterie said the scheme would initially target the 1.5 million solar power producers who, if they sign up to the community, will receive a battery storage system with a starting price of 3,599 euros ($3,812). But eventually, the offer will also be open to non-producers, it added. If the idea of battery-powered buildings takes off, it could pose a challenge to traditional utilities such as RWE and E.ON, which still derive the bulk of their power from big centralised power stations running on fossil fuels.   Full Article:

70% of Mongolian nomads now have solar power

by MIHAI ANDREI for ZME Science:  In many the vast steppes of Mongolia, some things have remained unchanged for centuries. But some things have changed, and big time: according to a new report, almost 3 out of 4 Mongolian nomads are now using solar power. Even if your lifestyle is pretty much Medieval, you can still benefit from advanced technology – that’s the reasoning behind a new government initiative that encourages nomads to use solar power. Mongolia is a geographically large but sparsely populated country. Covering over 600,000 square miles, it only has a population of 3 million people. About 1.2 million of Mongolia’s citizens live in the urban capital of Ulaanbaatar, while the remaining population is widely dispersed throughout the country with a large number residing in rural areas. In total, about a quarter of the population consists of nomadic herders. The per capita income in Mongolia at the start of the millennium was about US$470 per year, with income amongst herders even lower.   Cont'd...

Mercedes Is Proposing A Novel Solution To Meet Energy Storage Demand

By Michael McDonald for OilPrice.com :  Ever since Tesla announced its PowerWall battery project earlier this year, interest in stationary storage and battery technology in general has been explosive. Now, Mercedes Benz has put together an interesting project built around recycled batteries that might help drive even more interest in grid scale utility storage and help to blend the consumer and commercial markets for batteries. Under Mercedes’ new project, a consortium of companies is going to create the world’s largest grid storage facility using used batteries in Lunen, Germany. The project will have the capacity to store 13 megawatts of power (enough to meet the demand of 130,000 homes) based on reusing automotive batteries. The basic premise is that when the battery from an electric vehicle or a plug-in hybrid vehicle is no longer reliable enough to start a car, it still has up to 80% of its original storage capacity remaining. As a result, a large series of these batteries can be connected to store energy from renewable sources like solar and wind power.   Cont'd...

Toronto Hydro to test world's first underwater energy storage system

Dario Balca , CTV Toronto:  Toronto Hydro has announced it will launch the world’s first-ever underwater energy storage system in Lake Ontario. The utility has partnered with Hydrostor Inc., a company that specializes in innovative energy storage systems, for a two-year-pilot project intended to create a backup for the city’s electricity grid big enough to power approximately 350 homes. "We're very excited to see this new technology in action,” said Toronto Hydro CEO Anthony Haines. “Toronto Hydro has been very busy exploring new ways to power our grid, and I think this is the most creative project we've been involved in so far. Supporting innovative solutions for Toronto's power needs will continue to be a focus for our organization." The system works by taking electrical energy and converting it into compressed air so that it can be stored under water in large, balloon-like structures. The storage facility will be located three kilometres off the southern tip of the Toronto Island and 55 metres under water. When the city’s electricity grid needs power, crews will open a valve that lets the pressurized air out. The air is then converted back into electricity and fed into the grid.   Cont'd...

Why Wind Power Has Taken China by Storm

The rapid development of the wind power industry has created a new set of challenges for China to address. Despite this, the GWEC still predicts that China will install an additional 100 GW by the end of 2019, exceeding the country's 200 GW target for 2020 a year ahead of time.

Innovative energy storage project to be unveiled by Ryerson, eCamion

GREG KEENAN - The Globe and Mail:  Ryerson University in Toronto and a high-tech startup company called eCamion Inc. will unveil a pilot project Wednesday that allows energy to be stored in a unit that sits on hydro poles. An eCamion storage unit combined with a smart controller developed by Ryerson researchers and students will enable utilities such as Toronto Hydro to store power, integrate more renewable power and improve the reliability of the system, the company and Ryerson say. The unit uses lithium-ion batteries that charge during off-peak hours of hydro usage and discharge during peak hours. One of the benefits if the storage devices win widespread adoption is better availability of power for recharging electric vehicles, said Hari Subramanian, eCamion’s chief executive officer. “These are the enabling technologies you need for electric vehicles to really have an uptake,” Mr. Subramanian said. In many areas, the current hydro infrastructure could not handle the demand if several electric vehicles in a small section of a city were being recharged at the same time, he said. The storage device allows utilities to “flex their grid” to meet varying demands at various times, he said.   Cont'd...
