Sept 8 – ABB and China's BYD have entered a strategic collaboration to develop new solutions for energy storage, used to backstop the fast ramp up of renewables with energy storage in off-grid and on-grid solutions.
ABB's products and technology for grid storage, electric vehicle charging and integrated marine systems, combined with BYD's knowledge in battery technology, "can broadly address worldwide energy storage requirements," the companies said.
New electrolysis stack technology from Canadian developer Hydrogenics offers a megawatt conversion capacity of 85%, paving the way for advanced gas power energy storage. "Creating a highly efficient link between the electrical grid and the natural gas system power to gas unlocks the massive energy storage capacity which we have already built and paid for," Daryl Wilson, chief executive at Hydrogenics told Gas to Power Journal.
UK-based research firm Highview Power Storage and GE Oil & Gas have announced a licencing and technology collaboration agreement to develop large-scale liquid air energy storage (LAES) systems. The technology is “ideally suited” for gas-fired peaker power plants, according to GE who struck the partnership to explore opportunities to improve operations of existing plants through the addition of energy storage.
Feb 19 – The German government has awarded €6.5 billion for E.ON's 5-megawatt energy storage project, named M5BAT (modular multi-megawatt multi-technology medium-voltage battery storage).
Works on the power storage will start in the autumn and E.ON said it expects the facility to start operation in 2015.
The project is a unique battery storage system, E.ON said and will focus on "renewables integration, testing of distributed regulating energy provision to promote grid stability, and power price arbitrage."
A 500 kilowatt-hour peak load shifting unit is to be installed at the Discovery Science Center in Southern California by GE as part of efforts to reduce peak demand on the grid. The GE storage and Princeton Power Systems (PPS) inverter control system is expected to shift 10-20% of daily electrical load to off-peak time periods, freeing up peakload power supply for other users.
The California Public Utilities Commission (PUC) has voted in legislation to mandate 1,325 megawatts of energy storage in the state in a move set fast-track expansion of the power-to-gas sector. The PUC vote mandates Pacific Gas and Electric Company, Southern California Edison, and San Diego Gas & Electric to install extra storage capacity by 2020.
Oct 1 - The Spanish government has halted work on the Castor offshore submarine gas storage plant following more than 200 minor earthquakes nearby, off the eastern coast of Valencia.
The Castor facility is one of the country's biggest investments in gas infrastructure and is meant to cover 30 percent of Spain's daily gas consumption. It was the first European project to issue so-called "project bonds".
