    1. UK invests $22M in Isentropics Pumped Heat Electricity Storage system

      UK invests $22M in Isentropics Pumped Heat Electricity Storage system

      Can a humble system of gravel and a heat pump provide a breakthrough for utility-scale energy storage? British startup Isentropic thinks so, and this week announced that they’ve raised $22M in project funding and an equity investment from the Energy Technologies Institute (ETI), a collaboration between the U.K. government and companies in the energy industry.

    2. Pumped Hydro Can Pump Twice Daily Due To Solar Power

      Pumped Hydro Can Pump Twice Daily Due To Solar Power

      What’s new is that there is now a new low price trough in the afternoon in Germany due to solar power.  There is one peak price in the morning and another peak price in the late afternoon/early evening. In the mid afternoon on sunny days, wholesale prices are about the same as at midnight. This allows pumped hydro operators to recharge their reservoirs in the afternoon as well as the evening .

    5. Ontario's largest pumped hydro project proposed - height of four Niagra Falls

      Ontario's largest pumped hydro project proposed - height of four Niagra Falls

      The project will use an abandoned deep open pit iron mine.  A reservoir  above the pit will be constructed using nearby waste rock. When the cost of electricity is lower, water in the pit will be raised to the reservoir. In daytime, water from the reservoir can fall the distance of four Niagaras to run the generator deep in the pit.

    6. LightSail's Compressed Air Grid Storage Explanation (good overview)

      LightSail's Compressed Air Grid Storage Explanation (good overview)

      To make CAES more efficient, the LightSail system captures and stores both the mechanical energy and the thermal energy used in compressing air.  To do this, a water mist is infused into the compression chamber as the air is compressed. Water can hold 3,300 times as much heat as the same volume of air, and is able to capture the heat generated by the process more effectively.  Both potential energy in the form of pressurized air and the heated water can be stored.

    9. Analysis: Is Sodium Sulfur (NaS) a viable Grid Storage Solution?

      Analysis: Is Sodium Sulfur (NaS) a viable Grid Storage Solution?
      In September 2011, sodium-sulfur (NaS) batteries at a Mitsubishi Materials Plant in Japan, caught on fire. It took firefighters more than 8 hours to control the blaze, and two weeks to extinguish the fire. NGK Insulators, the company that manufactured the storage system, does not know the cause of the fire, has suspended production of its NaS cells, and advised customers to refrain from using their batteries.

    10. German offshore wind developer looks to Norway pumped hydro storage

      German offshore wind developer looks to Norway pumped hydro storage

      !f wind reaches 20-25% of electricity supply capacity, it could be meeting 100% of demand during off-peak times, making storage essential. “You need the Norwegians for that [for their pumped-hydro capacity]. … we have them on board, as Statoil, Statkraft are the partners of RWE on this project.” [said Vahrenholt of RWE Innogy]

      $15B Wind & Pumped Hydro Projects in Lesotho

      Contractor Harrison & White (Johannesburg) unveiled the Lesotho Highlands Power Project, to be comprised of 6GW of wind and 4GW of pumped hydro over the next 15 years. The projects will be built and equity provided by Harrison & White and the Lesotho government, while debt will come from several undisclosed Chinese financial institutions. The first project will be a 150MW wind farm that is slated to enter construction next year.
