Finland’s nascent grid-scale battery market is set to expand rapidly in the coming years, according to Landis+Gyr’s Northern Europe CEO Ari Tolonen.

He told Energy Storage Report his company was pursuing four other energy storage projects in Finland after completing the largest battery plant in the Nordic countries earlier this year.

Up to 4MW of battery storage could be installed across the country “very soon,” he said. “I believe we will see three or four cases a year. I expect to see this kind of system everywhere.”

In August, Landis+Gyr commissioned a 1.2MW, 600kWh battery system for Helen Electricity, a distribution system operator covering the Helsinki area of Finland.

The €2m Helen storage facility was built alongside Finland’s largest solar plant, a 340kW array in Suvilahti, and will also serve an 850kW PV project being built at nearby Kivikko.

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.

HyperSolar moves along lonely path to hydrogen

US-listed technology firm HyperSolar is looking to develop a commercial-scale solar-powered hydrogen generation system after unveiling a working prototype last month.

The Santa Barbara, California-based company is hoping to give the hydrogen fuel cell industry a boost by removing one of hydrogen’s biggest problems: having to transport the gas over long distances.

Hydrogen “is expensive enough in the manufacturing process,” said Tim Young, president and CEO. “When you add on trucking it 500 miles in a pressurised truck, it stops making economical sense.”

Being able to manufacture hydrogen on site, using water and sunlight, could eliminate these costs and open up a vast array of potential energy applications, Young told Energy Storage Report.

These include “thousands and thousands of backup power plants” that “would all love to be hydrogen powered” because the fuel can be stored indefinitely until needed, he said.

What does the PV glut mean for energy storage?

Present forecasts of PV-and-battery adoption could end up significantly underestimating true adoption levels by not taking into account a massive glut in solar capacity.

Josefin Berg, senior analyst for solar demand at IHS Technology, told Energy Storage Report there are currently “several gigawatts’” worth of new solar panels worldwide that nobody wants to buy because of excess supply.

IHS alerted to the potential for manufacturing overcapacity in the PV market back in June, and has forecast there will be a shakeout among what few manufacturers are still left from previous oversupply and consolidation periods.

For now, however, as EnergyTrend noted: “Prices across the PV supply chain have collapsed to new lows in the second half of 2016 due to plunging demand.”

What will happen to the excess PV capacity currently sitting on the shelf is unclear, but in Australia CleanTechnica earlier this month predicted it would lead to a “big solar boom.”

Azores project key for island microgrid credibility

A project on Graciosa, Azores, has become key for the credibility of island-based storage following concerns over another plant more than 1,500km away.

The Younicos project on Graciosa is set to go live within weeks amid speculation that another attempt to power an island off renewables, in El Hierro, Canary Islands, has failed to meet expectations.

El Hierro’s Gorona del Viento plant, which combines an 11.5MW wind farm with a pumped hydro storage system, was launched with much fanfare in 2014. Its initial aim was to replace 80% of diesel generation needed for the island grid.

Last month, the plant operator revealed the EUR€82m Gorona del Viento had allowed El Hierro to run continuously off nothing but renewable energy for 55 hours.

And last week Gorona del Viento said the plant supplied 67% of the island’s power throughout July and had set a new record of 76 hours with 100% renewable production.

Battery key to island’s hybrid system

SMA's Sint Eustatius hybrid solar, battery and diesel plant.

SMA has commissioned a hybrid solar, battery and diesel plant to reduce fossil fuel consumption on the Caribbean island of Sint Eustatius.

 

By Jason Deign

Inverter maker SMA Solar Technology yesterday confirmed commissioning of a hybrid battery, PV and diesel system covering the electricity needs of a small Caribbean island.

The system will allow the 21km2, 3,500-population island of Sint Eustatius, in the Caribbean Netherlands, to cut its fossil-fuel consumption by 30%, equivalent to 800,000 litres of diesel and 2,200 tons of CO2 a year.

The hybrid system includes a 1.9MW solar plant, which can cover more than 23% of the island’s 13.5GWh annual electricity demand, plus 1MW of battery storage.

Diesel genset integration is through SMA’s Fuel Save Controller 2.0 software. SMA also supplied a Sunny Central Storage 1000 battery inverter and a Medium Voltage Power Station 1000.

This “enables a measured solar fraction of up to 88% during sunshine hours and supports the grid with stability functions such as frequency regulation, ramp-rate control for PV and optimisation of diesel genset operation,” SMA said.

Peer-to-peer (P2P) power supplier Open Utility is planning to pressure the UK electricity market regulator towards introducing grid-balancing measures that could include energy storage.

The company, which runs an energy marketplace called Piclo, hopes to convince the Office of Gas and Electricity Markets (Ofgem) that P2P networks are good for consumers and distributed generation asset owners.

“There are significant benefits in better balancing renewables and demand on a local electricity network,” said James Johnston, Open Utility’s CEO and co-founder. “Energy storage will be key in enabling this balancing.”

Currently, he said, UK regulations do little to encourage the use of energy storage in P2P networks. Piclo, which allows businesses to buy renewable power directly from source, does not currently include storage, for example.

However, Johnston said: “If regulations allow for it, incentivising local balancing using P2P energy matching could unlock significant financial rewards for local consumers and generators.”

Viking launches solar-and-cold-storage combo

By Jason Deign

Viking Cold Solutions, a US thermal energy storage start-up, is launching what is likely the world’s first solar-plus-cold-storage combination at Hannover Messe, Germany, this week.

Energy Storage Report understands the offering is not so much an integrated product as a concept aimed at raising awareness of the efficiency of cold storage over batteries.

Using cold storage with grid power can improve the efficiency of energy use by up to 34%, Viking Cold claimed.

Combined with solar, it could cut ongoing energy costs much further while providing a quicker return on investment (ROI) than batteries, the company said.

“We aim for a three-year payback,” said James Bell, president and CEO. “Our return on investment is based on energy savings. The bigger the facility, the bigger the savings. It can be tens of thousands of dollars a year.”
