Energy use of crypto-currencies – bitcoin in particular – has been criticized as 'unsustainable' although estimates are wide-ranging at 20‑80 Terrawatt-Hours (TWh) annually. Through the first six months of 2019 bitcoin mining consumed some 29 TWh, up significantly from around 45 TWh in 2018, the International Energy Agency (IEA) finds.
ExxonMobil and Global Thermostat have developped an agile solution of soaking up carbon dioxide emissions from the air – notably from industrial facilities and power stations. Test runs are currently underway at a pilot plant at SRI International, an R&D facility in California. The data collected there will help ExxonMobil evaluate possibilities to scale up the application.
Turbine inlet temperatures already exceed the melting points of turbine blade materials in modern facilities but researchers have come up with a novel approach to turn the heat even higher. Nekomimi film cooling, developed by Kawasaki and B&B Agema, allows to further increase temperatures at the combustor exit and high-pressure turbine stage inlet.
Pouakai NZ, part of the US infrastructure investor 8 Rivers Capital, is developing a clean hydrogen, fertiliser and power generation facility at a cost of up to $4 billion. The plant, designed to produce clean hydrogen for use in power generation and supercritical CO2 for enhanced oil recovery, is expected start operations by 2024.
The European Union has dedicated €4 million ($4.5m) for research on new designs for biogas-fuelled, small-scale cogeneration engines - in a bid to open up the heat and power sector for mainstream renewables. Named SmartCHP, the solution could have a market potential of up to €4billion, according to the lead research coordinator, BTG Biomass Technology Group.
Comparing fuel costs, the International Energy Agency (IEA) said hydrogen-based direct iron reduction for steel production could allow for substitution to green energy – if the hydrogen is generated from electrolysis. “Hydrogen could become an attractive option to indirectly electrify industrial high-temperature heat," analysts said, "either via direct combustion or blending with natural gas.”
General Electric has decided to close down the 750 MW Inland Empire Energy Center (IEEC) in California some 20 years before the end of its lifetime. The steam-cooled H-class turbines had taken hours to start and repeatedly suffered technical problems, which hampered a swift dispatch of the CCGT and ultimately rendered it uneconomical.
Feasible Inc., a Californian battery analytics platform company, has received a major cash injection from Chrysalix Venture Capital’s RoboValley Fund to help promote its newly-developed intelligence platform EchoStat. Based on real-time analytics, the system provides actionable insight to solve challenges related to battery design and manufacturing.
General Electric has developed three new grid analytic methods that combine domain expertise with artificial intelligence (AI) and machine learning (ML) to tackle challenges in electric grid operations. The offer addresses storm readiness, network connectivity and inertia in a bid to enable more stable grid operations and security of power supply.
Norwegian energy giant Statkraft and flexible grid specialist Statera have entered a 15-year partnership to develop a 1 GW virtual power plant (VPP) in the UK. Consisting of flexible reciprocating gas and energy storage, the VPP will match demand with supply from various energy sources “within seconds.” Ultimately, the partnership is meant to bring Statkraft’s VPP capacity to 2 GW.
Kawasaki Heavy Industries of Japan is advancing the development of a floating power plant that will operate on regasified LNG, targeting utility customers in remote areas of Southeast Asia. The barge-based LNG-to-Power solution will be the first of its kind able to generate 100,000 kilowatts of electricity.
