Ballard Signs Supply Agreement With Solaris; Receives Initial Order For 10 Fuel Cell Modules For Trolley Buses
Power-Technology.com - Quidnet Energy is hoping to revolutionise energy storage with its underground pumped hydro concept, which uses abandoned oil and gas wells to store and release pressurised water, driving turbines and feeding electricity back into the grid. How does the concept work and how far could it go? Quidnet co-founder Aaron Mandell explains.
As the cost of renewable energy continues to decline and intermittent clean power sources such as wind and solar gain ever an ever larger foothold in the global energy mix, the ability to store energy that can be quickly dispatched when needed has become as important as the development of renewables themselves.
Robust storage options could allow for greater integration of intermittent renewables, as they facilitate flexible capacity-building that relies far less on coal and gas-fired plants for baseload generation, meaning energy storage is a key step in the journey to wean the world off its fossil fuel addiction.

Toshiba Promotes Move to Hydrogen Economy with Construction of Integrated Hydrogen Application Center
Avery Thompson for Popular Mechanics: The first tidal generator in North America has gone online this month in the Bay of Fundy, and is expected to generate enough electricity to power 500 homes.
While most hydro generators harness the energy of falling water, or the energy of the waves, tidal power uses the energy of the high and low tides. At the Bay of Fundy in Nova Scotia, which has the largest tides in the world, that energy is being harnessed to generate 2 megawatts of electrical power.
In the Bay of Fundy, the difference between high and low tide is about 56 feet. Approximately 115 billion tons of water flow in and out of the bay every tidal period. Two renewable energy developers, OpenHydro and Emera, decided to build turbines on the seafloor that could harness that power. Cont'd...
