After several years of preparation, Kosovo* is moving ahead with the largest solar thermal project for district heating in the Western Balkans. The pre-qualification tender for a 44 MW collector field with seasonal storage in Pristina, Kosovo, ended on 11 April 2025. This expansion will be driven by the introduction of larger-scale ground-mounted solar parks, contributing to the country's goal of achieving 400 MW of solar capacity. . Kosovo* is developing the Western Balkans' largest solar thermal district heating project, supplying 32,000 citizens with renewable heat while expanding its network with coal plant cogeneration. The estimated time for completion is 30 months plus a six-month commissioning phase. The heat supply in Pristina is particularly inefficient, CO2-intensive and predominantly covered by two coal-fired power plants. The district heating system, however, meets only around 25% of the demand.

The need for long-duration energy storage, which helps to fill the longest gaps when wind and solar are not producing enough electricity to meet demand, is as clear as ever. Several technologies could help to meet this need. But which approaches could be viable on a commercial. . Compressed Air Energy Storage (CAES) has emerged as one of the most promising large-scale energy storage technologies for balancing electricity supply and demand in modern power grids. Think of it like charging a giant “air battery. Compressed air energy storage (CAES) is a promising solution for large-scale, long-duration energy storage. . Air energy storage power generation projects are revolutionizing how we store and utilize renewable energy.

Given that the ideal operating temperature for a solar inverter is approximately 25 °C (Ketjoy et al. 2021a, b) managing heat remains crucial for ensuring longevity, optimizing efficiency, and minimizing thermal losses (Xiao et al. . Solar air conditioning, or "solar-powered air conditioning", refers to any air conditioning (cooling) system that uses solar power. This can be done through passive solar design, solar thermal energy conversion, and photovoltaic conversion (sunlight to electricity). Best for off-grid or hybrid systems. Most mini splits use 500-700 watts per hour per evaporator zone. The indoor unit is installed inside the room, while the outdoor unit is installed outside. . Instead, they cool by evaporation: a fan pulls hot, dry air through wet pads; the evaporation absorbs heat and lowers the air temperature. Pros: Very low energy use, simple, quiet, minimal maintenance, can run easily from a small PV setup.
