Using Industry 4.0 Know-how, North German Region is Going 100% Renewable: Test Run for the Energy Transition
As of 1 December 2016, an energy system of the future will be developed in Northern Germany as part of the large-scale project NEW 4.0. From 2035, around 4.5 million residents in the federal states of Hamburg and Schleswig-Holstein will be provided with power by renewable energy sources alone. Applying Industry 4.0 systems, the project will demonstrate how imbalances in production and consumption can be offset based on renewable energies. Northern Germany is playing an important role in Germany's energy transition: Schleswig-Holstein as an energy supplier with an ever increasing number of onshore and offshore wind farms, and the city state of Hamburg as a location for industry and large power consumers. As part of the NEW 4.0 project, the states of Hamburg and Schleswig-Holstein have been merged into one consistent energy region. The overall objective is to serve as a showcase for Germany and to demonstrate within a European context that the energy transition is indeed feasible: NEW 4.0 will showcase how a region with 4.5 million residents can be supplied with regenerative energy as early as 2035 using 100% safe, affordable, eco-friendly and socially acceptable energy sources that can lead to a reduction in CO2 emissions by 50 to 70%.

Jocelyn Timperley for BusinessGreen: A new energy storage technology currently under development by Siemens is set to see excess wind energy converted to heat rocks, allowing the energy to be stored using an insulated cover. The system consists of a fan that uses an electrically-heated air flow to heat the stones to high temperatures, with the thermal energy then converted back to electricity when needed using a steam turbine. The simple principle of the set-up promises to deliver a low-cost way of storing energy, Siemens said, with the only limit to the concept being the space required for the rock-filled insulated container.

High Tech High Chula Vista strives to empower its students to ask the big questions and make big changes in the world. Climate change is one of the most pressing issues in our world, making solar energy one of the most effective responses that HTHCV has at its disposal.
Derek Markham for TreeHugger: This startup is reinventing the solar panel, and aims to cut the cost of integrating clean power and energy storage to homes by half. Home solar has the potential to reduce, and even eliminate, electricity costs for many people, but even with the rapid advancements we're seeing in solar technology, there are still weak points that can be addressed and overcome, such as energy storage and 'smart' home integration. But a newcomer to the residential solar scene believes it has the answer, in the form of a standalone solar and battery unit which can be used singly or connected in an array, and which may be able to lower the overall costs considerably. SunCulture's SolPad solar device integrates solid state batteries directly into the solar panels themselves, offering its users the ability to not only generate their own clean electricity, but to also store if for use after dark or during peak demand times, when electricity costs are higher. The SolPad units also incorporate an inverter, which converts the electricity from the DC generated and stored by the device to the AC required by most household appliances, and includes "intelligent software" that communicates with both the users and with their home's systems, allowing for granular control over which rooms or devices will receive the solar power.

Robert Ferris for CNBC: Elon Musk tweeted on Thursday that he hopes to unveil a Tesla/SolarCity solar roof with a new integrated battery pack and Tesla car charger on Oct. 28. Musk first began teasing the next generation Powerwall at an event for Tesla owners in Paris earlier this year, according to Electrek. At the time, he had said the company would roll out the new battery in "July or August." SolarCity's merger with Tesla has aroused skepticism and even ire from some investors and analysts, even after Musk outlined his reasons for combining the two companies in his second installment of his "Master Plan" in late July.

Katie Fehrenbacher for Fortune: Solar panel maker and farm developer SunPower is embracing the latest in computing technology to help lower the cost of its solar panel farms while minimizing the impact that the farms have on land. The Richmond, Calif.-based company on Tuesday announced an array of new technology that it’s using to design, build, operate, and monitor big solar panel farms that are built to sell energy to utilities and large companies.

Experts anticipate cost reductions of 24%-30% by 2030 and 35%-41% by 2050, under a median or 'best guess' scenario, driven by bigger and more efficient turbines, lower capital and operating costs, and other advancements
In the last ten years, the installed global solar energy capacity has multiplied nearly 50 times. The cost of purchasing and installing a solar panel has decreased by 80 percent in five years and is still falling. The comparable cost of electricity generation has made solar energy the cheapest energy source today, from being the most expensive only six years ago. This is truly a green revolution.

Katherine Tweed for GreenTechMedia: In many parts of the world, wind power is cheap. That is particularly true in the U.S., where onshore wind already rivals the cost of natural gas in some regions. But wind power will likely get even cheaper, according to new research from Lawrence Berkeley National Laboratory published in Nature Energy, with contributions from the National Renewable Energy Laboratory, University of Massachusetts, and participants in the International Energy Agency Wind Technology Collaboration Program. The study surveyed more than 160 wind experts across the globe. Many had deep expertise in very specific regions, but the overall findings were similar: The cost of wind will continue to come down through 2030. There are significant variations in the current costs for wind by region, but researchers "found a considerable amount of agreement” in overall reductions as a percentage of that total cost, said lead author Ryan Wiser, a senior scientist at Berkeley Lab.

By Reuters: “We fear a second wave of bankruptcies,” said the head of an association of EU solar producers. A sharp increase in solar power production in China and a sharp fall in domestic demand have sparked a sudden surge of cut-price exports, undermining a China-EU agreement to limit damage to European producers. China produced 27 gigawatts (GW) of solar photovoltaic (PV) modules in the first half of 2016, an increase of 37.8 percent and installed 20 GW of new solar power capacity in the same period, three times as much as the same period a year ago. However, demand has since tailed off. Solar projects operational since July face a reduced price paid by grid operators for their power. Cont'd...
The efficiency gain equals to approximately $2.5M additional energy being produced over a 100MW power plant's lifetime, on average at the global level.
ScienceDaily: Energy storage is crucial for taking full advantage of solar power, which otherwise suffers interruptions from cloudy skies and nightfall. In the past few years, concentrating solar power plants have begun producing additional electricity at night and during peak demand periods by using stored heat energy to propel a steam turbine. Current thermal energy storage systems rely on materials that store less energy per kilogram, requiring more material at a greater cost to meet energy storage requirements. Now, researchers at the U.S. Department of Energy's (DOE's) Argonne National Laboratory have designed an inexpensive thermal energy storage system that will be significantly smaller and perform more than 20 times better than current thermal systems.

The SolarEdge PV inverter combines sophisticated digital control technology with efficient power conversion architecture to achieve superior solar power harvesting and best-in-class reliability. The fixed-voltage technology ensures the solar inverter is always working at its optimal input voltage over a wider range of string lengths and regardless of environmental conditions. A proprietary data monitoring receiver has been integrated into the inverter and aggregates the power optimizer performance data from each PV module. This data can be transmitted to the web and accessed via the SolarEdge Monitoring Portal for performance analysis, fault detection and troubleshooting of PV systems.
