Sorption heat storage system performance heavily depends on the operating temperature. It is found that testing temperatures reported in literature vary widely. In respect to the building application for space heating, reported testing temperatures are often outside of application scope and at times even incomplete. This has led to application performance overestimation and prevents sound comparison between reports. This issue is addressed in this paper and a remedy pursued by proposing a static temperature and vapor pressure-based testing guideline for building-integrated sorption heat storage systems. By following this guideline, comparable testing results in respect to temperature gain, power and energy density will be possible, in turn providing a measure for evaluation of progress.

“…Thermochemical energy storage can offer a low pressure and low seasonal energy requirement at high energy densities [144]. It was predicted that thermal energy storage and hydrogen storage may develop rapidly and have the most promising applications in the future [145]. Dominkovic and Krajacic [146] built an integrated model to optimize the share of district energy supply versus individual cooling and reduce the operating costs in energy systems with and without proper energy storage solutions in Singapore.…”

The global COVID-19 pandemic has had strong impacts on national and international freight, construction and tourism industry, supply chains, and has resulted in a rapid decline in the demand for traditional energy sources. In fact, research has outlined that urban areas depend on global supply chains for their day-to-day basic functions, including energy supplies, food and safe access to potable water. The disruption of global supply chains can leave many urban areas in a very vulnerable position, in which their citizens may struggle to obtain their basic supplies, as the COVID-19 crisis has recently shown. Therefore, solutions aiming to enhance local food, water and energy production systems, even in urban environments, have to be pursued. The COVID-19 crisis has also highlighted in the scientific community the problem of people’s exposure to outdoor and indoor pollution, confirmed as a key element for the increase both in the transmission and severity of the contagion, on top of involving health risks on their own. In this context, most nations are going to adopt new preferential policies to stimulate the development of relevant sustainable energy industries, based on the electrification of the systems supplied by renewable energy sources as confirmed by the International Energy Agency (IEA). Thus, while there is ongoing research focusing on a COVID 19 vaccine, there is also a need for researchers to work cooperatively on novel strategies for world economic recovery incorporating renewable energy policy, technology and management. In this framework, the Sustainable Development of Energy, Water and Environment Systems (SDEWES) conference provides a good platform for researchers and other experts to exchange their academic thoughts, promoting the development and improvements on the renewable energy technologies as well as their role in systems and in the transition towards sustainable energy systems. The 14th SDEWES Conference was held in Dubrovnik, Croatia. It brought together around 570 researchers from 55 countries in the field of sustainable development. The present Special Issue of Energies, specifically dedicated to the 14th SDEWES Conference, focuses on four main fields: energy policy for sustainable development, biomass energy application, building energy saving, and power plant and electric systems.

[11] TCS, which can upgrade the stored heat at an arbitrary temperature with high heat storage densities, [12][13][14][15] and no heat loss, [16] is more suitable for efficient utilization of low-grade thermal energy.…”

3D Graphene (3D‐GF) modified with different additive concentrations (phytic acid [PA] and ascorbic acid [AA]) is developed and then combined with different LiOH contents by the hydrothermal method to obtain composite materials. It can be found that the addition of PA and AA will not destroy the carbon skeleton structure of 3D‐GF. With increasing additive content, the thermal conductivities of modified 3D‐GF first increase and reach their maximum values at 8 mg mL−1. The modified 3D‐GF with the highest thermal conductivity is selected to be combined with different LiOH contents. The addition of PA and AA can broaden the charging temperature range from 60–110 to 30–200 °C and improve the LiOH hydration rate and heat storage density. Compared with the PA‐modified composite, the AA‐modified composite shows smaller (about 7.6 nm) and more uniform LiOH·H2O particles (the particles size standard deviation of 3D‐GF‐AA‐LiOH·H2O is 1.1503), a larger specific surface area (119 m2 g−1), higher heat storage density (the highest value of 2763 kJ kg−1 for LiOH⋅H2O, which can be about 4.2 times of pure LiOH), and less influenced by the change of LiOH content (the thermal conductivity standard deviation of 3D‐GF‐AA‐LiOH·H2O is 0.123).
