Summary: Energy storage is crucial for decarbonizing the electricity sector, especially in residential installations. Home energy management applications play a vital role in enabling active control of appliances and storage systems to achieve efficient energy utilization. However, the emergence of renewable generators and electric vehicles poses challenges due to uncertainties in residential asset operation. This paper introduces a novel home energy management tool that addresses these uncertainties by using a Lexicographic-Interval formulation and prioritizing the impact of random parameters. A benchmark case study validates the proposed tool and demonstrates its ability to handle different tariffs.

Summary: A novel solar-air source heat pump system is proposed to efficiently and stably supply heat in the cold area of North China by using the latent heat of water in the ice tank as the main low-temperature heat source, complemented by solar energy and outdoor air. The system can also be used for cooling in summer, and combined with night energy storage to minimize building operation energy consumption and cost. The optimized system shows efficient operation under extreme weather conditions and a dynamic investment payback period of 3.86 years, presenting a promising way to meet building energy supply in cold areas.

Summary: Many subarctic communities heavily rely on fossil fuels for energy, but solar-assisted ground-coupled heat pumps (SAGCHP) can integrate renewable energy sources. However, it is unclear how such systems would operate in the high North with cold ground, mismatched insolation, and diesel electricity. This paper aims to model a SAGCHP heating a house in Nunavik, Canada to understand its potential and limitations. Simulations were conducted with and without battery storage, revealing complex tradeoffs between four modes of operation. Over ten years, the SAGCHP system reduced fuel consumption by 38.2% (without battery) and 59.1% (with battery).

Summary: This research develops a model to enable the flexible operation of direct air capture (DAC) and maximize the usage of renewable energy. The results demonstrate that DAC can adapt to variable renewable energy without the need for battery energy storage. Furthermore, using physical storage silos could be more cost-effective than using battery energy storage.

Summary: This study compares empirical data on citizen-led renewable energy capacities in Poland with results obtained from a meta-theoretical, empirical analysis of the national energy system. It summarizes the essential factors explaining the low level of citizen energy in Poland, such as a centralized energy system, social, regulatory, and technical lock-ins. Furthermore, the study finds that the size of citizen-installed renewable capacities and the number of collective initiatives in Poland are limited due to various barriers.

Summary: Energy performance contracts are a promising avenue for attracting private investments in renewable energy. This paper presents a hierarchical model of a decentralized energy system with renewable sources and energy storage under a service agreement. The model showcases the interaction between the client and the performance company, considering parameters like net present value, contract duration, and levelized cost of energy. An example of a decentralized power system using only diesel generation is used to demonstrate the benefits of building a photovoltaic system with optimal equipment composition and contract terms, resulting in significant fuel savings.
