Energy storage systems developer Demand Energy and Latin America microgrid pioneer Rio Grande Renewables this week announced a record-breaking project in Costa Rica.
The two companies have commissioned a battery storage-plus-solar-PV microgrid at Establishment Labs, a Costa Rican medical manufacturing plant, said Demand Energy in a press release.
The microgrid is said to be the largest in Central America and includes a 500kW, 1MWh lithium-ion battery connected to 276kW of solar PV.
The system is designed to provide multiple on-site and grid-assisting services, including peak demand reduction, solar variability smoothing and backup power for critical loads in the event of an outage.
It is controlled by Demand Energy’s Distributed Energy Network Operating System (DEN.OS™), which optimises how energy storage, distributed generation and other distributed energy resources interact and perform. Read more →
Delegates at next year’s Energy Storage Europe Conference will hear a plea for open business models (Pic: Energy Storage Europe 2016).
Energy storage developers and asset owners should aim to be technologically neutral to make the most of global markets, experts will hear next year.
Florian Mayr, partner and storage expert of management consultancy Apricum, is due to make the case for technologically open business models at the Energy Storage Europe Conference 2017 in Düsseldorf, Germany.
These models can benefit most from the growth of international storage markets as flexibility becomes a key factor for success in the industry, he claims.
“Today storage markets are still comparatively small and characterised by individual, often geographically determined application cases,” he said. Read more →
The Dulas solar-powered direct-drive vaccine fridge uses phase-change materials to store vaccines more effectively, helping save human lives.
By Jason Deign
Phase-change materials (PCMs) are boldly going into an energy storage realm where even the most modern battery technologies have failed to deliver: saving lives.
Dulas, a Welsh renewable energy technology company, is using PCMs in place of batteries as an essential component of solar-powered direct-drive refrigerators for off-grid vaccine storage in developing countries.
On Monday the company announced a contract to supply 345 of its VC200 fridges to health and aid agencies working in Yemen, Sierra Leone and Nigeria.
The company said the deal represented “a significant expansion” of its partnerships with the World Health Organisation (WHO), the United Nations Children’s Fund (UNICEF) and the Institute of Human Virology in Nigeria.
Dulas will be sending 60 fridges to the Institute of Human Virology, 143 to the WHO in Yemen and 142 to UNICEF in Sierra Leone. “There is the potential for further orders in the near future,” said the company. Read more →

A UK energy storage system developer is looking to go from 650 installations today to 1m by 2020 with an aggregation-based residential business model.
London-based Moixa Energy Holdings is positioning itself as a utility’s friend by aggregating residential storage assets into a virtual power plant that provides ancillary grid services, then sharing the rewards with its customer base.
On its website, the company claims its GridShare service can earn homeowners between GBP£50 and £75 a year, or “almost 15% of the average electricity bill.”
Chief executive Simon Daniel told Energy Storage Report that 2016 was a scaling-up year for Moixa, which began piloting smart battery technology in 2012 and launched its current products two years ago.
The company is expecting to shift up to 100,000 storage systems within the next 36 months, Daniel said. And although Moixa is looking to bolster sales abroad, most of that capacity could go online in the UK. Read more →

Military enthusiasm for energy storage applications is at an all-time high, according to one supplier close to the industry.
“There’s no doubt that their interest is strong,” said Ryan O’Keefe, senior vice president of business development at the power conversion systems maker Ideal Power.
Energy storage is seen as one of a number of technologies that can help military chiefs offset costs and risks while allowing troops to operate more independently in the battlefield, he said.
“They identified quite some time ago that their military bases, wherever they are, are at the mercy of the electric grid. The military is clearly in planning mode for how to make their operations resilient.”
Ideal Power is currently working with “a couple” of military suppliers on how to improve frontline logistics and power quality. Read more →
