Siemens, the state of Saxony and the Fraunhofer Institute have signed a ‘future pact for Görlitz’ and committed to invest around €30 million to develop a competence center for hydrogen technologies. The initiative is meant to ease the effects of region’s structural transformation which has been hit by Siemens’ closure of a long-running turbine manufacturing site.
Power system flexibility is a prerequisite of the clean energy transformation. Fossil power plants were for long deemed vital to ensure flexible supply and system inertia, but “if modern wind and solar power plants are technically able to provide frequency regulation, they should be allowed access to ancillary services, as was done in Spain,” said Enrique Gutierrez, energy analyst at the International Energy Agency (IEA).
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.”
