Florida, USA-based energy storage start-up Concept by US is due to start shipping its all-in-one battery systems to Africa in May.

For the African market, the company has created a 50Hz, 220V, three-phase version of its Powerstation 247 Plus integrated battery system. It will be installing the units in Africa on behalf of an un-named African energy firm.

Units will be going into African locations ranging from high-end resorts to small off-grid communities, said Sara Kissing, vice president and chief operating officer.

The Powerstation 247 Plus is a solar, wind and diesel genset-ready edition of what Concept by US claimed was the market’s first true integrated home storage system when it launched last year.

Concept by US expects to sell 800 units this year, split almost evenly between African and America. In the US, the company’s biggest markets are California, Texas and Florida.

The concept that could put AC on ice

Thermal energy storage such as that being commercialised by Ice Energy may have a much greater impact than just doing away with the duck curve.

If sold at scale, it could also effectively put traditional air conditioning (AC) out of business in large areas of the world where AC is essential for daytime workplace and home cooling.

Ice Energy is already bracing itself for growing demand in sunny US territories where increasing distributed solar penetration is causing regulators to move away from net metering plans.

In places such as Hawaii, the shift away from net metering is depriving solar-equipped homeowners of electricity bill reductions and forcing them to look at alternative ways to save money with PV. Powering AC units is one option.

AC is one of the biggest daytime and evening energy loads of households in hot locations. With net metering, much of electricity you need to drive AC units can come for free from any excess you have poured into the grid.

Ice Energy’s plan to end the duck curve

Thermal energy storage developer Ice Energy is gearing up to increase sales of a product that has the potential to end California’s famous ‘duck curve’.

The Southern California Public Power Authority (SCPPA) has already announced plans to buy up to 100 of Ice Energy’s Ice Bear 20 residential cooling systems, which completed testing about a month ago.

The 20 ton-hour systems use energy when there is excess production, for example at night, to create ice that is then used for cooling during peak electricity consumption periods, such as evenings.

“At 9.6kW per Ice Bear 20, the order will potentially add nearly 1MW of new energy storage and peak demand reduction capacity to the SCPPA network, saving energy, improving efficiency and reducing emissions,” said Ice Energy.

The deal marks Ice Energy’s debut in the residential energy storage market, a move the company unveiled in Energy Storage Report last year, and follows growing utility interest in using Ice Bears for demand response.

The utility response to grid defection

Utilities are seeking new ways to respond to grid defection as the economics of solar-plus-storage make it easier for homeowners to disconnect.

A report called The Economics of Grid Defection, by the Rocky Mountain Institute (RMI), concludes that in territories such as Hawaii off-grid solar plus storage is already economically competitive with remaining on the electricity network.

Tens of millions of customers will defect in other areas such as California and New York as solar plus storage achieves grid parity by 2030, and possibly even 2020, the RMI predicts.

And grid defection is by no means a US-only phenomenon.

In many parts of Australia and Germany, for example, the business case for residential PV and storage is still far from convincing, but that has not stopped homeowners from installing systems for a whole host of other reasons.
