US firm Eos Energy Storage has signed two deals in as many weeks as it looks market its aqueous, zinc hybrid technology for off-grid and grid-connected applications.
US firm Axion Power International is set to install a lead-carbon off-grid energy system following a deal with Schneider Electric and fellow American firm Tennessee Solar Solutions.
The system will store energy from renewable sources to power a mobile sustainability laboratory developed by Tennessee based company Urban Green Lab.
Solara now owns the stand-alone unit’s customer and supplier structure as well as all international and European rights to the Solara brand, PV-Tech reports.
"Our goal is to develop the areas of mobile and stationary applications nationally and internationally, as well as expand the existing battery and micro systems business for single and multi-family households in the domestic market," said Frank Heise, one of Solara’s founders.
"The acquisition of the Stand Alone System division ensures the survival of the very well-known brand Solara, particularly in the leisure segment, and we can also focus on other business fields in Germany that are independent of subsidies," Heise added.
The modules are mainly used on boats and motorhomes as well as for rural electrification in developing countries.
Centrosolar employees Frank Heise, Walther Grauerholz and Mirko Held founded Solara in August this year and offers mini grid and backup systems for the solar sector.
Centrosolar has initially filed for bankruptcy, but withdrew the proposed insolvency plan on September 14. Due to conflicts of interest among the creditors, the plan cannot be implemented in the short term. The company group also has a US branch that sells solar modules for residential homes and is not affected in the recent troubles.
US-based Navitas Systems has launched a transportable remote power system with integrated energy storage and power inverter electronics.
According to Navitas Systems, the so-called Frontierion system can be connected to a flexible or rigid solar panel, enabling DC power from the solar panels or the integrated energy storage (lead acid or lithium-ion batteries) to be converted to stable and secure 115/220V AC, 12V DC, and 24V DC power output.
The system is aimed to incorporate multiple layers of protection to include short circuit protection, over-current protection, and externally resettable protection without the need of opening the box.
The Frontierion system is designed to allow users to rapidly deploy and re-deploy mobile power systems that require no fuel for continuous and secure power. The remote power system can come with different sized energy storage modules, ranging from 1.2kWh to 10kWh of total capacity.
“The applications for this new product are numerous, and range from an insurance company's 'Go-Team' responding to a tornado and processing on-site claims while plugged into Frontierion, to a Border agent powering his equipment while the vehicle's engine is off, to a remote construction site needing power for computing and communications,” said Navitas Systems CEO Mil Ovan.
Navitas Systems recently launched a lithium battery family, designed to replace currently used lead-acid batteries in commercial, industrial and military applications.
US sodium-ion battery developer Aquion Energy has elected energy industry expert Tom McDaniel to its board of directors.
McDaniel currently works as director and chairman of the board at smart grid and energy management company Tendril Networks and as director of solar energy firm SunPower. He also works for SemGroup, On Ramp Wireless and Cypress Envirosystems.
A 5MW solar-diesel hybrid power plant connected battery storage is to be installed in Bolivia's Pando province.
Solely diesel generators are currently powering the remote area, located 4,000 metres above sea level and not connected to Bolivia's national grid. The 5MW solar plant is designed to meet half of Pando's capital city Cobija's power demand. The city has 45,000 residents.
Inverter manufacturer SMA is to provide controlling systems, central inverters and battery storage. "The SMA Fuel Save Controller records the energy flows in the stand-alone grid and uses that information to determine the maximum permissible PV power. In this way, we can guarantee permanent system stability and ensure smooth control of the gensets," said SMA senior vice president off-grid and storage Volker Wachenfeld.
Spain's engineering firm Isotron is currently carrying out the construction of the plant.
The plant is aimed to reduce the annual consumption of 20m litres of diesel and save $3m of fuel costs.
The solar power plant is set to start generating 2MW of electricity later this year and increase the capacity over the following months. According to SMA, it is worldwide the biggest plant of its kind.
The plant is fully state-owned.
Microturbine manufacturer Capstone Turbine has signed a contract for a factory protection plan (FPP) for nine C1000 microturbines at Horizon Power Systems locations.
Energy supplier Horizon Power Systems aims to cover nine turbines that currently operate in remote central gas gathering plants in the US Rocky Mountain and mid-continent regions, with the 9MW FPP.
The FPP is an addition to $175m in product backlog and increased the total contract backlog for Capstone Turbine’s FPPs to a record of over $55m.
The Capstone Turbine FPP is designed to secure the reliability of the company’s turbines offering a risk-transfer solution that aims to limit the monetary risk of unplanned maintenance over the contract life. Capstone Turbine power packs, in which the turbines are integrated, reduce flared gas and cycle it back into the production process.
"Most oil and gas producers work in remote locations where an electric utility grid is not an option or unreliable. The Capstone Turbine microturbine becomes the sole source of critical low emission power that our customers have come to rely on," said Sam Henry, president of Horizon Power Systems.
The FPP is set to run over nine years.
Horizon Power Systems has currently over 600 Capstone Turbine microturbines in operation.
US-based Apel Steel has commissioned energy solutions provider ACE LLC Solar to install its energy storage system (ESS) at the company’s 340KW PV plant.
The utility-scale energy harvesting, monitoring and distribution system aims to move the PV plant off the grid to make metal manufacturer Apel Steel independent from the grid.
The ESS, called enerGStation, has a three-phase power at up to 2MW in increments of 100kW. Each integrated inverter is rated at 100kW and can be configured in parallel to provide a 2MW system. The system uses renewable energy when available and sufficient. Otherwise, it uses local energy storage from batteries to deliver the total energy demanded by loads.
The plant is designed to meet 98% of Apel’s annual power demand for its heavy machinery and plant operations. The ESS will save the Alabama company more than $3M on its electricity bills over the 30-year life expectancy of the system, according .
Suntech produced the solar panels and Tenessee-based ACE LLC Solar conducted the final installment of the PV plant along with its ESS.
Ballard Power Systems and Anglo American Platinum (Amplats) are to test a fuel cell-powered microgrid prototype in a remote rural community in South Africa.
The companies will power 34 households in a 12-month trial with a generator system that is fueled by methanol and uses platinum group metals as catalysts. The fuel cell system is integrated into a prototype off-grid solution incorporating a battery bank and inverters that operate within the microgrid.
The system is designed to provide a total of 15kW of power and generate peak power of 70kW.
"This field trial will provide valuable insight into the market requirements of off-grid communities,” said Andrew Hinkly, executive head of marketing at Amplats. South Africa’s Department of Energy (DOE) has chosen the rural community of Naledi Trust as a suitable site for the trial as the area does not have any access to grid power and expanding the national network would be too expensive.
The next phase of the project will be the installment of 200 to 300 units in remote villages across the country, according to Godfrey Oliphant, South Africa’s Deputy Minister of Mineral Resources.
Ballard and Amplats are collaborating with power utility company Eskom and South Africa’s DOE to conduct the field test.
