Energy Storage

Los Angeles Department of Water and Power (LADWP), a municipal utility, has confirmed plans to convert its Intermountain Power Plant in Utah from coal to natural gas, and then to 100 percent hydrogen. Right from the start of the new 840 MW gas power unit in 2025, hydrogen will fuel 30% of its operation and the ratio will be increased to full hydrogen fuelling by 2045.

The United Kingdom and Germany are ready to expand their cooperation in offshore wind and take the lead on hydrogen production in Europe. Together, the two countries are home to 85% of Europe’s installed offshore wind farms whose excess low-cost electricity output can be used to produce hydrogen, which can then be stored in the natural gas grid.

Setting the pace for modular onsite power, Aggreko will install a hybrid power unit at Resolute Mining’s operation fot the Syama gold project in Mali. The expandable 70 MW hybrid plant will reduce the mine’s electricity costs by 40% by combining thermal and solar generation with battery storage.

Tesla’s decision to build Gigafactory-4 – its first European factory for battery cells and e-vehicles – in German is expected to bring an “enormous boost” for the country's lagging shift to electric mobility. Economy minister Peter Altmaier called the surprise announcement by Tesla CEO Elon Musk a "milestone" for the production of battery cells production and the rollout of e-mobility.

Sun-soaked Saudi Arabia is taking steps to use excess renewable energy to evolve into a global supplier of commercially competitive hydrogen. Mitsubishi Hitachi Power Systems (MHPS), developer of a large hydrogen gas turbine, says Saudi Giga-scale projects like NEOM can help the kingdom achieve its transformation to a ‘Hydrogen Society’.

Nearly all utility-scale battery systems installed in the United States over the past five years use lithium-ion technology, according to government findings. Provided all battery system additions will be completed as planned, and no capacity is retired, the total battery storage capacity in the U.S. could exceed 2,500 MW by 2023.

China-Australian Maoneng Group has been selected by AGL Energy to install four batteries with a total capacity of 200MW/400MWh in New South Wales by 2023, underpinned by a 15-year offtake agreement. The aim is to ensure stable supply and power prices at times of peak demand.

2019 will be a record year for investment in advanced lithium-ion batteries with over $350 million already spent in the first half of the year, notably by automotive giants and oil companies. This figure indicates that full-year 2019 investment will be higher than the last year’s $600 million.

Manufacturing capacity of all types of lithium-ion sub chemistries is expected to grow to just over 770 GWh by 2026. More than half of this manufacturing resides in China today but other key markets like Germany, Sweden, Hungary and Poland will ramp up production starting from 2021.

Highview Power is about to switch on the world’s first cryogenic, or liquid air, energy storage at a decommissioned thermal power station in the north of England. Provided developers can secure a stable, contracted return, the 50 MW/250 MWh CRYOBattery will start operation by 2022.

New York Public Service Commission has given the green light for the Ravenswood project, a 316 MW battery-based energy storage that would replace ageing fossil-fuelled capacity in NYC. If built, the project will be the first major use of energy storage for peakload power in the U.S. Northeast.

Bracing against the risk of wild-fires, the Californian utility Pacific Gas and Electric (PG&E) shut off electricity to hundreds of thousands of customers in 34 California counties. The impact of these shutoffs could have been buffered by supplying electricity from energy storage facilities.

Slovenian energy solution provider NGEN has invested over 15 million Euros to install the largest Tesla Powerpack storage system in Europe. The 12.6 MW/22.2 MWh battery energy storage system (BESS) is used for grid balancing and will soon be accompanied by a second, similar-sized unit.

In California, energy storage is becoming a viable alternative to peakload gas power units. Pacific Gas & Electric (PG&E) is developing utility-scale storage with a combined capacity of 567.5 MW and 4-hour duration, aiming to replace three gas-fired power plants.

German engineering giant Siemens is partnering with Hydrogen Renewables Australia (HRA) to develop a 5,000 MW wind and solar farm in Western Australia. Siemens electrolysers will convert the renewable power into low-cost renewable hydrogen for export to Asian markets.
