Energy Storage

Scientists at the University of Maryland have developed an organic polymer electrode which they claim demonstrates stable function for a sodium-ion battery over 50,000 cycles and also offers encouraging performance in magnesium-ion and aluminum-ion storage devices.

In this interview, pv magazine sits down with Greg Tremelling, VP of business development at Oztek Corp, to talk about his company’s semi-custom solutions and where he sees the energy storage industry going.

The microgrid utility has raised enough capital from Shell New Energies to deploy systems across sub-Saharan Africa.

The Smart Energy Hub can operate in electrolysis mode to store renewable energy as hydrogen, or in fuel cell mode to produce electricity and heat from previously produced hydrogen or methane. Its developers are the French Alternative Energies and Atomic Energy Commission and start-up Sylfen.

The French energy giant has acquired U.K. start-up Pivot Power, which has a 2 GW pipeline of storage projects in Britain.

The Swiss multinational has opened a production facility for energy storage systems for the mobility market and placed a 900 kW rooftop array on one of its Italian factories.

The recycling market will experience a tenfold expansion between last year and 2030, driven by EV battery usage and portable electronics. Retrieving valuable metals and minerals is becoming a high priority and several dozen companies are already in position for the first big wave of end-of-life batteries.

As higher concentrations of renewable energy and storage capacity come online, the control systems of today cannot solve the problem of a two-way predictable grid of the future. Enter Pxise Energy Solutions (pronounced “Pice”). Using real-time data and algorithms to make intelligent decisions, the company’s software technology is breaking down barriers for grids to operate with high levels of renewable penetration. Pxise says its software can unleash the benefits that batteries are able to provide.

This has been a breakthrough year for non-battery storage, with key advances in pumped hydro, power-to-gas, and thermal storage technologies. Many industry players are moving beyond pilot projects to contracted projects, which could lead to increased scale and lower costs.

The islands of the Caribbean have been focusing on the deployment of storage solutions, minigrids and microgrids in response to the damage their power systems suffered during the 2017 hurricane season. But with the opportunities, there are also challenges.
