Energy Storage
One of the key factors that will determine the amount of gas used in power generation over future years is the cost and effectiveness of energy storage. The cheaper the storage, the more intermittent renewables will be able to be introduced to grids, and the less gas that will be required; especially in higher latitudes where solar is not available part of the year.

Oct 5 – Working with the utility Hamburg Energie the Technical University Hamburg Harburg (TUHH), Siemens is developing a thermal storage solution to be paired with wind energy, which it hopes “will set a future standard in efficiency.” Excess wind energy is used to heat rock-fill, protected by an insulated cover – when stored electricity is needed a steam turbine converts the heat energy back to electricity. Tests in spring 2017 will evaluate the energy conversion of a 36 MWh test bed based on a container holding approximately 2,000 cubic meters of rock-fill.
The world’s largest lithium-ion battery power storage – a 20 MW/80 MWh Tesla Powerpack – will be put in place at SoCal Edison’s Mira Loma substation in an effort to better harness renewable energy sources. California Public Utilities Commission (CPUC) had mandated an accelerated procurement of power storage to counteract energy shortages following the Aliso Canyon gas leak.
Aug 30 – EDF Energy Renewables, the UK renewables arm of the French utility, will install a 49 MW battery power storage at its West Burton CCGT in Nottinghamshire. The final decision was made after EDF won a contract as part of a 200-MW Enhanced Frequency Response (EFR) tender by the UK's National Grid.
A total of eight projects secured contracts in the EFR tender; other winners include Vattenfall, Low Carbon, RES, Element Power, E.on UK and Belectric.
Aug 25 – Southern California Edison has selected a subsidiary of AltaGas to build a 20 MW storage project with a discharge capacity of 80 MWh east of Los Angeles. AltaGas Pomona Energy Storage will build, own and operate the project, which is estimated to cost up to $45 million and is meant to be operational by December. State regulators urge utilities to procure storage to avoid power outages.
Aug 25 – More than 20 days after Malta’s Prime Minister Joseph Muscat attended the ‘Sail-away Ceremony’, the gas storage ship destined to support power stations in Malta is still docked in Singapore. No fixed date has been set for its departure – so it is unclear whether will reach Malta as planned in mid-September.
Affordable storage is seen as the missing link between intermittent renewable power and reliable energy supply. McKinsey research anticipates costs could fall to $200 per kWh in 2020 – half of today’s price, which would help transform the energy mix of many nations. By 2025, costs of power storage are expected to fall to $160 kWh or less, making it affordable to use for utilities and grid operators.
China National Petroleum Corporation (CNPC) and Russia’s Gazprom have agreed to form a joint venture for gas-fired power generation and underground gas storage in China. The MoU was signed on Saturday after detailed discussions on Russian gas supplies via the western route – the so-called ‘Power of Siberia’ pipeline is already under construction.
Flexibility of power network hinges on storing excess electricity and demand response to alleviate the impact of intermittent generation. California and Germany used subsidies as a trigger to advance power storage; yet to further commercialise these technologies the industry needs market-based regulation that remunerates flexibility and puts in place a level playing field between different assets.
News in Brief
FlatFish drone inspects Shell fields off Brazil
May 25 – Shell and Petrobras have contracted Saipem to use its FlatFish subsea drone in pilot projects to inspect two ultra-deepwater oil and gas fields offshore Brazil in over 2,000-meter depth. Initial tests will be carried out at Saipem’s base in Trieste, Italy, with a view to deploying the drone to Brazilian waters in the third quarter of 2022.
Gazprom cuts off supplies to Finland
May 24 – Gazprom has completely suspended gas supplies to Gasum after the Finish company refused to pay in roubles, the two companies said in separate statements. Gasum is confident it will be able to supply all its customers with gas imported through the Balticconnector (2.6 Bcm/y) from Estonia.
Heisco wins tender in Kuwait
May 23 – Heavy Engineering Industries and Shipbuilding Company (Heisco) has won a KD1.8 million ($6.4 million) tender – floated by the energy ministry of Kuwait – to install, examine and test four high voltage transformers at the Doha East Power Generation and Water Distillation Station. Heisco, founded in 1974 and listed on the Kuwait Stock Exchange, has developed into one of the largest energy engineering groups in the emirate.
JERA issues bond to finance power plant upgrades
May 20 – Japan’s leading LNG importer and power producer JERA has issued its first energy transition bond to help finance the accelerated deployment of decarbonisation technologies like hydrogen and ammonia co-firing, as well as the decommissioning of older thermal power stations. The bond is offered in two tranches: a 12 billion yen ($83 million) for a 5-year bond with a 0.420% per annum coupon, and a 8 billion yen $62 million) for a 10-year bond with a 0.664% rate coupon.
Rolls-Royce conducts laser field tests in the US
May 18 – Rolls-Royce has successfully conducted laser field tests to demonstrate ‘deep magazine’ power capability for directed applications in connection with Lockheed Martin’s layered laser defense project. Deep magazine power can be provided by a battery-only system, but the Rolls-Royce ColdFire system includes both battery-powered and near-continuous firing modes provided by M250 gas turbine engines.
Gas vs oil ratio increases in the Bakken
May 17 – The ratio of natural gas to crude oil production has risen in North Dakota’s Bakken region since 2008, and continues to accelerate. According to the US Energy Information Administration's (EIA) Drilling Productivity Report, annual gas gross withdrawals in the Bakken increased by 9% to an annual high of 2.97 Bcf/d in 2021, even though the region’s crude oil production fell by 6%.
Middle East shifts to gas power
May 16 – The Middle East, a region vulnerable to climate change, is undergoing a major shift from petroleum-based power plants towards gas-fired generation and renewable power sources. Capacity additions of over 185.46 GW are the pipeline, according to ResearchandMarkets, as the regions electricity demand for industry and residential cooling is set to grow. In fact, cooling already accounts for 70% of residential power demand.
Carbon utilisation in strong demand
May 13 – The market for carbon utilisation is forecast to grow rapidly from the 2030s onwards to surpass $285 billion by 2042, driven by rising climate commitments and a favourable regulatory framework. In its latest report IDTechEx also highlights the role of technology advances such as thermodynamics which help sequester CO2 permanently.
MTU gensets approved for biofuels
May 12 – Rolls-Royce has gained approval to use synthetic fuels in its MTU Series 4000 and Series 1600 diesel engines for power generation application. Field testing confirmed both engines can use a range of sustainable fuels including biomass-to-liquid, hydrotreated vegetable oil and power-to-liquid fuels such as e-diesel.
E.ON tells Germans how to save gas
May 11 – A large-scale switch to heat pumps, solar power and better demand-side management could help save Germany nearly 100 TWh of natural gas per year, E.ON has said, calling on households to contribute to Europe’s efforts to reduce reliance on Russian gas imports. “If 10% of the homes in Germany are equipped with solar PV installations, 20% of gas boilers are replaced by heat pumps, and the average temperature in all households is reduced by one degree Celsius on average, this would lead to natural gas savings of 103 TWh per year," E.ON Energy CEO Filip Thon said, noting this volume would equate to about 30% of Germany’s current gas imports from Russia.
Exelon Q1 earnings lower following Constellation cave-out
May 10 – Exelon has reported lower first quarter earnings and a higher operating revenue, having completed the separation of Constellation Energy – Excelon’s former power gen business. Focussing now solely on transmission and distribution, Exelon’s net income from continuing operations for the first quarter of 2022 decreased to $0.49 per share from $0.53 a share in pre-year period. In contrast, adjusted operating earnings notched up to $0.64 per share, primarily due to due to higher electric distribution earnings at ComEd from higher rate base and higher allowed electric distribution. Rate increases at Excelon’s group companies PECO, BGE, and PHI were partially offset by higher depreciation expenses at BGE and PHI.
