Vienna is building Europe's largest green heat pump system and aims to become climate neutral by 2040. The scheme, which uses heat from wastewater at the Ebswien purification plant and electricity from the Freudenau hydroelectric power plant, is a pioneering initiative in Europe. The first phase of the project, which will cost around €70 million, will provide district heating to 56,000 homes. The three remaining large heat pumps are expected to double the system capacity by 2027, providing climate-neutral heating to 112,000 homes. Vienna's heating network is one of the largest in Europe.
Bulgaria is focusing on energy storage in its energy transition, investing in battery production plants and battery energy storage systems (BESS) to promote the establishment of hydrogen valleys. Sofia-based startup Hydrogenera has signed its first contract for a 1-MW electrolyser capable of producing 200 cubic meters of hydrogen per hour, or 436 kilograms of hydrogen per day. The company is part of the European Clean Hydrogen Alliance and the Hydrogen Global Initiative. The 1 MW electrolyser is expected to be delivered by the beginning of the second quarter at the latest. Hydrogenera has a 200 kW flagship model with an efficiency of 85%. The company raised €2 million a year ago and is considering an initial public offering next year.
Portland Trust has sold rights to a 255 MW photovoltaic investment project in Romania’s Corbii Mari commune to Nofar Energy. The deal is worth more than €120 million and is expected to start next year with annual production of 362 GWh. Nofar Energy is an Israeli company with a portfolio of operational and renewable energy projects under development in Romania, including the country’s largest photovoltaic plant. Portland Trust is also involved in other major solar power investments in Romania, including the Vişina photovoltaic system and the Otenia 1.5 GW solar power scheme. The deal is expected to support Romania’s national decarbonization strategy.
HyHome is Australia's first hydrogen-powered home, equipped with a hydrogen-powered hot water system, heating, stove and barbecue facilities. The Australian Government's National Hydrogen Strategy has identified hydrogen in the gas grid as a priority area for research, trial and demonstration programmes. HyHome equips the domestic market with 100% hydrogen-compatible appliances. However, challenges in blending hydrogen into the gas grid include allocating the resources required, ensuring compatibility with current gas grid pipes and fittings, and addressing safety concerns. The Australian Hydrogen Center reports that a 100% hydrogen network would reduce network capacity by 13%.
Ready-mix concrete company UltraTech Cement Limited aims to increase its green energy share to 85% by 2030, triple its green energy share to 60% by FY2026, and meet 100 of its green energy needs through renewable energy by 2050. % of electricity demand. The company has a total green energy installation capacity of 691 MW, of which 262 MW comes from waste heat recovery systems and 429 MW from contracted renewable energy. UltraTech is also exploring carbon capture, utilization and storage (CCUS) with startups CarbonOrO, Coomtech and Fortera.
GreenCell Mobility, a pioneer in the electric vehicle (EV) space, has signed a power purchase agreement and made a strategic equity investment in a 1 MW wind-solar hybrid captive power plant in Ratlam, Madhya Pradesh. This measure will reduce CO2 emissions by approximately 38,000 tonnes over the life of the buses and is in line with GreenCell’s long-term ambition to become a net zero company. The company is also exploring the deployment of battery energy storage solutions to ensure end-to-end green operations.
