    Moving the electricity sector into a low-carbon future presents many challenges. As supply becomes increasingly intermittent, so the need for fast-responding, flexible demand and generation sources grows. Energy storage is a key source of flexibility to meet this need and has been identified by the UK Smart Grid Forum as a crucial intervention likely to be required for the future smart grid.
  • Panasonic Corporation announced it installed the "Power Supply Container," as a stand-alone photovoltaic power package that it developed, to the National Elementary School Karimunjawa 01 in Karimunjawa Island, Jepara District, Central Jawa Province, Indonesia.
  • AFC Energy plc, a developer of alkaline fuel cell technology, has entered into a heads of agreement with Daniel Inc., a fuel cell focused power plant owner and development company, for an initial 1MW fuel cell system with a follow-on option for a further 3MW project making a total potential sales value of approximately $15 million.

    In today's data center landscape, it has become increasingly important to maintain uptime for business continuity. To avoid costly downtime and sustain uptime in the case of a power event, facilities operators have to deploy a comprehensive power distribution scheme along with emergency power support from an uninterruptible power system (UPS).

    Aluminum occurs is abundance in the earth’s crust and has directly and indirectly plays a role in the energy sector, with prospects to play an expanded role in the future. About a decade ago, one of the world’s large aluminum companies posted job openings for doctoral graduates in chemistry, to develop polymers or long-chain molecules based on aluminum.

    This is the first of our talks with IEEE. In it, Noel Schulz discusses how IEEE's power and energy society (PES) is evolving and how engineers can evolve with it. (And, yes, how you can get that school to put your name over the door.)

    I recently joined a discussion about how gravity might be used to generate and store energy. One of the comments provided a link to Gravity Power, a company that has proposed a modified take on "pumped storage" whereby a vertical water reservoir is used with a heavy piston. During the discussions a few variations on this technology were proposed. I suggested that abandoned open pit mines might represent a good starting point for very large facilities.

    Earlier this week I spoke with an old friend, who works in the utility practice group of a major management consulting firm.  We commiserated about the challenges of getting conservative electric utilities to adopt new technology. My friend opined that the only way to get the attention of utility management is to paint a picture of Armageddon. And there is no surer way to do that, he said, than by talking to them about distributed generation.

    While Ontario has for decades been North America's largest electrical utility, it has often been plagued by political controversy. Many an elected official has used the utility as a means by which to achieve a political agenda. Ongoing political agendas have left the utility saddled with massive debt.

    David Mohler, vice president of emerging technology with Duke Energy advises that "our work to seamlessly integrate storage within a diverse grid ecosystem and unlock its full value is just beginning."

    In January, a report from the Edison Electric Institute painted a bleak picture for the future of investor-owned utilities. It essentially said that the IOU business model, under the current regulatory environment, is not sustainable in the face of expected growth in rooftop solar.

    Mark M. MacCracken, a former chair to the US Green Building Council (USGBC),  gives some insight into California's Resolution E-4586, which will implement a standardized permanent load shifting (PLS) program applicable to SCE, PG&E and SDG&E.

    Grid-scale energy storage technologies are set to play a crucial role in the today's evolving power system. System operators and utilities are continuously working to improve grid efficiency and reliability and look to storage technologies to do so. Storage can lend a helping hand in implementing numerous applications, including renewable integration, power flow optimization, frequency regulation, and congestion management. However, it is important to utilize technologies that can accomplish this in the most economic and efficient way. Let's take a look at the different storage methods that are in use today.

    One of the biggest concerns with many forms of renewable energy is their inability to store active energy during times when the sun isn't out, or when the wind isn't blowing. With these energies gaining popularity and growing at an impressive rate, it seems as though establishing an efficient form of energy storage is a foregone conclusion for the future.

    In February of this year the U.S. Army Corps of Engineers' Engineer Research and Development Center - Coastal Hydraulics Lab (ERDC-CHL) reported that it had deployed the largest Wave Energy Converter (WEC) in the US at their Field Research Facility in Duck, NC. According to their posting, their facility hosted a wave surge actuated device (a system in the "onshore systems" category of pendulor devices, as described by the Department of Energy). The Navy has also tested a wave energy device (more in the general DOE category of "offshore systems") at Marine Corps Base Kaneohe (MCBH). According to a Navy Times posting of last year, the intent is to provide wave produced power to Marine Corps Base Kaneohe, HI by 2014.
