Two of the UK's biggest energy providers will now appear together at Scottish Renewables Annual Conference after new speakers were confirmed for the event.
Megan Geuss for ArsTechnica: Pumped storage is a decades-old technology with a relatively simple concept: When electricity is cheap and plentiful, use it to pump water up into a reservoir above a turbine, and when electricity is scarce and expensive, send that pumped water down through a turbine to generate more power. Often, these pumped storage facilities are auxiliary to other electricity-generating systems, and they serve to smooth out fluctuations in the amount of power on the grid. A German research institute has spent years trying to tailor pumped storage to ocean environments. Recently, the institute completed a successful four-week pilot test using a hollow concrete sphere that it placed on the bottom of Lake Constance, a body of water at the foot of the Alps. The sphere has a diameter of three meters and contains a pump and a turbine. Much like traditional pumped storage, when electricity is cheap, water can be pumped out of the sphere, and when it’s scarce, water can be let into the sphere to move the turbine and generate electricity.

Fisher Auto Parts, one of the largest regional auto parts distribution and marketing organizations in North America, announced today that the installation of a 63.7 kW photovoltaic solar energy system has been completed at their Staunton, VA headquarters.
Phys.org: A major roadblock to the mass use of solar energy are photovoltaic (PV) solar cells. This is because the cost, inefficiency and negative environmental impact that the manufacturing of these cells outweighs any potential savings provided by the resulting solar energy. If, however, cost could be were minimised, then solar power would be more able to compete with traditional fossil fuel-based methods for generating energy. To overcome this hurdle, the EU-funded SOLNOWAT project has developed an innovative dry process for manufacturing PV solar cells. PV cells are typically created via a wet chemical process that etches away layers of silicon from a crystalline wafer, leaving behind the solar cell. The SOLNOWAT process replaces the expensive and inefficient wet chemical process with the use of atmospheric pressure dry etching technology – a process that cuts costs and speeds up production. Because less silicon is removed during dry etching, the resulting cells are darker, making them very efficient at absorbing light. In fact, they are so efficient that they have been classified as having zero global warming potential. Cont'd...
NH Research, Inc. (NHR) has released the new 9300 series, a higher-voltage / higher-power version of its popular single-channel 9210 series battery test systems. The 9210 Series provided a 12kW power module operating at 40V, 120V, or 600V and which allowed paralleling with similar systems to increase the power, whereas the new 9300 system provides a 100kW power module with a software-selectable high voltage range (1200VDC / 167A) and high-current range (600VDC / 333A) allowing for efficient testing of single-voltage and double-voltage Electric vehicle (EV) batteries as well as high-voltage Energy Storage Systems (ESS) used in grid-tied applications.
Solect acquired Brightergy's Northeast sales and project management operations in addition to some of Brightergy's intellectual property developed around commercial solar lead generation.

Mike MunsellĀ for GTM: Ā "The fourth quarter marked a turning point in the U.S. utility-scale energy storage market reflected by the burst of deployments over an extremely short period from inception to interconnection," said Ravi Manghani, GTM Research's director of energy storage. "CaliforniaĀ will play a significant role in the future as utilities there continue to contract energy storage under the state's 1.3 gigawatt mandate. While California took over the pole position in 2016 from PJM, the market shift was also transformational in terms of applications -- from short duration ancillary services to longer duration capacity needs." As a result, even though the market stayed roughly flat in megawatts, it grew 100 percent in megawatt-hours. Ā Cont'd...
According to Infiniti Research, the cumulative installed wind capacity will reach 791.0 GW by 2020, growing at a CAGR of 12.81%. With many countries testing the limits of what wind and other renewables can provide, renewables such as wind will become more ubiquitous over the coming years.

Shoshanna Delventhal for Investopedia: The Trump administration’s stance on climate change and the environment can be summed up by the chief White House strategist’s recent criticism of government support of green energy as “madness.” Despite a 180-degree shift from Obama administration’s environmental agenda, the Department of Defense, plans to move forward with a decade-long effort to “convert its fuel-hungry operations to renewable power,” senior military officials told Reuters. Yet apart from the controversial debate on climate change and the need for environmental protection, the Department of Defense has a strictly nonpolitical incentive to carry out the transition. Weaning reliance off petroleum means improved safety for U.S. troops and the American public. Cont'd...
