Utility Scale Storage

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.

A team of scientists led by the University of Glasgow has discovered a more efficient method of splitting water into hydrogen and oxygen using electricity which it says could almost double the amount of hydrogen produced per millivolt.

The Balkan nation is planning a tender for 50 MW of utility scale solar capacity on a public-private partnership basis with help from the International Finance Corporation. The World Bank’s private finance arm is procuring a technical, environmental and social consulting firm to advise on the project.

The government of the Philippines will spend $500 million on solar-powered water supply and desalination in remote areas of Mindanao, the second-largest island in the archipelago. Elsewhere, a Finnish study has suggested drought-hit Iran could benefit from renewable-powered desalination.

Canadian business Caledonia Mining Corporation plc wants to build a power plant at its Blanket mine near Gwanda, in southern Zimbabwe.

The South African utility has issued a 20-strong tender for 50 kW solar inverters and mounting structures, to be used in four power plants. Although it is unclear whether the tender marks the energy company’s first step into solar energy, the procurement follows the recent publication of South Africa’s Integrated Resource Plan. Eskom is reportedly developing a renewables-linked large scale storage project which may explain the need for inverters.

Although PV trails wind and nuclear in terms of its anticipated future footprint, the opposition party’s attempt to outflank left of center rivals on climate change has resulted in one of the world’s most ambitious national roadmaps towards a zero-carbon future.

The Netherlands-administered Caribbean island last year saw almost half its power demand provided by a 4.1 MW solar-plus-storage plant, commissioned in late 2017. The facility generated 6.5 million kWh of the 14.3 million kWh of electricity consumed in the territory in 2018.
