Aira launches residential heat pump with minimalist design
The Sweden-based heat pump provider said its new product is one of the slimmest and most compact system available on the market to date.
What does the UK budget mean for solar, storage?
Spending commitments outlined by UK Chancellor Rachel Reeves include investment in planning departments, more funds for heat pump grants, confirmation of funding for commercial hydrogen projects, and more cash for the Department of Energy Security and Net Zero.
As more buildings use heat pumps, four technologies can provide grid support
Wider use of electric heat pumps to heat buildings creates a larger market for renewable energy, but also presents challenges, which can be met through building insulation and weatherization, cold climate heat pumps, thermal energy storage systems, and higher-voltage distribution grids, a report says.
New sun simulator, light-soaking tools for perovskite solar cells, modules
MBJ Solutions, a German testing equipment specialist, recently launched two new products for developers of perovskite and perovskite silicon tandem devices. The MBJ Steady State Sun Simulator is designed for cells and small perovskite module research, and the MBJ Light Soaking Unit is for aging tests and preconditioning.
Arriba Technologies launches solarized heating-cooling system
Arriba Technologies, a UK heating and cooling specialist, has developed a solar-integrated heating and cooling unit with a DC electrical system, all in a single package. It is installed at a 750 kW plant at Cambridge’s Rosie Hospital and won the Lighthouse Heat Pump Award at the European Heat Pump Association’s heat pump forum in September.
Climate data-based methodology for residential air-source heat pump sizing
A European research team proposed a new air-source heat pump sizing approach that utilizes long-term climate data and adjusts system operation based on actual local climate conditions. The sizing algorithm incorporates peak heat demand, unitary final energy demand, and seasonal heat demand across different house sizes.
With or without PV, air-source heat pumps are among cheapest residential heating sources
New research from Germany shows that identifying the cheapest residential heating source remains challenging, as the final results depend on the assumptions made and energy prices. The scientists, however, demonstrated that air-water heat pumps and gas heating systems are currently the most cost-effective solutions.
BASF receives funding for world’s largest industrial heat pump
The German government has awarded a €310 million ($336 million) funding package to chemical manufacturer BASF for the construction of an industrial heat pump with a capacity of up to 500,000 metric tons of steam per year. It will use waste heat from steam crackers for CO2-free stream production.
Dutch PV sector calls for consumption incentives as end of net metering looms
Dutch trade body Holland Solar is urging the new Dutch government to introduce self-consumption incentives for batteries, boiler tanks, and heat pumps used in combination with PV systems, as the country plans to phase out net metering by 2027.
Air-to-water heat pump for solar-assisted district heating
Researchers in Denmark have found that using a large-scale air-to-water heat pump in solar district heating may significantly reduce its levelized cost of heat. The proposed system configuration was simulated for an existing district heating plant in Denmark and was found to improve the flexibility of the system in response to energy prices.
