“…Research in the field of green deep learning, which is a part of ML, includes optimizing neural network architectures to require less computing power and exploring new ways to train models more sustainably, aims to develop more energy-efficient algorithms and hardware, which reduce the carbon footprint of these technologies [71]. Another important technology is the energy-to-heat conversion technologies (P2H), which transform surplus electrical energy into heat to be stored and used when needed, improving the overall efficiency of energy systems [72].…”

The paradigm of sustainable energy is gaining ground at the historical juncture of the present worldwide push for sustainable development. This is being driven by the latest technological advancements and by a maturing process of public policy evolution toward support for a sustainable energy transition. This paper analyzes, with the support of bibliometric analysis, the specialized literature in order to capture the main themes of interest, as well as their evolution, thus offering a panoramic view of research trends and the significance of implementing correct environmental measures and policies. Covering the period from 1991 to 2024, our exploration filters 2990 articles from the Web of Science database using a query that intersects “sustainable energy”, “renewable energy”, and “sustainable development”, with a nuanced consideration of the political landscape that shapes these domains. Using the advanced capabilities of the R program, the methodology employed facilitates a nuanced workflow of extraction and analysis, allowing for a detailed examination of the proliferation of research over the decades. This paper provides significant results, demonstrating the increasing impact of research through international collaborations, the importance of high-impact journals on sustainability policies, and the growing focus on “renewable energy” and “CO2 emissions”. The analysis of the relevance of term groups in environmental policy development and the correlation between economic growth and CO2 emissions confirms emerging trends. Furthermore, critical directions for future research and the necessity for formulating and implementing coherent sustainability policies are highlighted.

“…Electric heaters, which are commercially available in capacities up to 70 MWh, offer versatile applications in producing both steam and liquid heating media. These heaters can operate as electric resistance or electrode boilers for steam generation and as electric resistance heaters for liquid heating [18]. Direct electrification of industrial process heat has been shown to be applicable across various operational levels within the chemical sector, including central sites, sub-central operations, and unit operations [19,20].…”

The UK chemical industry is the largest consumer of natural gas for process heating and power generation, with an annual consumption of 26.3 TWh and accounts for 2% of UK’s total emissions. Industrial electrification enables moving away from fossil fuels to electricity for generation of lower carbon process heating. This study aims to accelerate the adoption of electric boilers in the UK's chemical industry, aligning with the UK’s ambitious 2035 industrial decarbonisation goals while considering economic impacts, by designing market-based policy interventions and comparing two adoption patterns. A novel multi-period Mixed-Integer Market Penetration Optimisation Model is developed and applied to inform decisions about transitioning from natural gas to electric boilers. The model is applied to a case study of all the heating systems (490 boilers) in the UK chemical industry from 1 MW to 60 MW boilers. At 100% uptake of electric boilers in 2033, the total carbon emissions reduce by 89%, which is above the 2035 UK industry goal of 60% reduction. Results show that effectively implementing a gas tax, electricity subsidy, annual grant and carbon tax can generate sufficient demand-pull to reduce the cost of electric boilers from 30 to 85% depending on the boiler size. A carbon tax starting at £280 per tCO2e and reducing to £170 per tCO2e coupled with electricity subsidies is essential for this transition. The policies are designed such that a win-win is achieved between government and industry; specifically, revenue from the carbon tax and gas tax is used to support the grant and electricity subsidy thereby achieving cost neutrality for government. The research establishes a robust policy timeline that can drive industrial electrification in the UK's chemical sector. It highlights the need for a multi-faceted approach, incorporating various policy instruments to overcome the barriers of high initial capital costs.

“…This technology is advantageous due to the comfortable, silent, and safe operation of the devices, low initial cost, ease of maintenance, energy storage capability, and integration with renewable energy generation devices. The classification of electric heat generation devices in residential and industrial buildings is presented in various studies [8][9][10]. In the vast majority of small-sized households and commercial premises, electric boilers are used, where the conversion of electrical energy into heat is based on resistive heating [11][12][13][14][15][16].…”

The improvement of energy efficiency in HVAC equipment makes the greatest contribution to reducing the environmental impact of household technical equipment on the natural environment. Currently, electric water boilers with resistive heating elements have gained the widest popularity for autonomous household heating systems. Thermoresistive semiconductor heating elements (РТС) represent a new direction in the production of electric water heat generators. An experimental wall-mounted electric boiler with РТС thermoresistive heating elements, with a nominal thermal power of 8 kW-h, was investigated. The characteristic of the РТС heating element within the boiler’s heat exchange unit was determined as a function of temperature. The energy efficiency in the power modulation range of 0.65-8.0 kW-h ranged from 0.983 to 0.988. The specific maximum power of the РТС element was 20 watts/cm2, and the hydraulic resistance of the boiler at a flow rate of 1.0 m3/h was 0.38 m.w.c. Electric indirect heating unit, installed in the design of the serial-produced electric boiler, passed the full test cycle and showed higher energy performance than when using a standard indirect electric heating unit with resistive ETH. Considering that РТС elements have significantly higher reliability and service life, it is recommended to release a trial batch of electric wall-mounted boilers for autonomous household heating systems and small industrial facilities.
