“…They mentioned that the heat produced by the solar thermal systems varied between 263-433 KWh/m 2 of the solar mirror while the seasonal coefficient of performance of the heat pumps varied between 2.42-2.61. Gurieff et al, 2020 have examined the possibility of creating energy hubs in community hospitals. The authors stated that public hospitals consume large amounts of energy while they have the opportunity to lead the transition to renewable energy.…”

“…Our work is focused on the investigation of using several sustainable energy technologies covering the energy requirements in hospitals and zeroing their net-carbon emissions due to energy use . These clean energy technologies include energy saving technologies, renewable energy technologies as well as low carbon emission technologies (CADDET, 1977, Franco et al, 2017, Gurieff et al, 2020. The possibility of using several financial mechanisms for supporting the clean energy investments in hospitals is also studied.…”

Mitigation of climate change, which is a severe global environmental problem, requires the sharp decrease of greenhouse gas emissions. Hospitals and healthcare facilities consume large amounts of energy compared with other organizations while they mainly use conventional fuels and grid electricity. The aims of the current study are: a) to review the sustainable energy technologies which can be used in hospitals minimizing their carbon emissions due to energy use, and b) to review the existing financial tools which can support the investments of clean energy technologies in hospitals. Published literature indicates that several benign energy technologies have been used in hospitals in developed and less-developed countries. These include: a) energy saving technologies, b) renewable energy technologies, c) low carbon emission technologies, and d) technologies related with green transportation. The most of them are reliable, mature and cost-efficient. Their combined use results in lower carbon emissions in hospitals. Any remaining emissions can be offset with the existing carbon offsetting schemes. Various financial mechanisms can facilitate investments of clean energy technologies in hospitals. It is concluded that several benign energy technologies combined with carbon offsetting schemes can assist hospitals to zero their net carbon emissions due to energy use while the existing financial mechanisms can facilitate and support the required energy investments. The present study is useful to policy makers and hospital’s authorities who are looking forward to minimize the carbon footprint in these organizations complying with current policies for achieving net zero carbon emission societies in the coming decades.

“…The results showed that the expected decrease in the battery prices will improve the resilience of RES when combined with BESS in applications that need high reliability like hospitals in islanded mode. Hospitals as a critical and resilient facility within the public sector facilities can be a leader for the development of flexible demand in the transition to higher shares of RES, and can provide innovation and learning for BESS as a new energy technology in the public sector [32]. The integration of RES with flow batteries is considered to replace backup combustion generators that are used to provide emergency power, to enhance the security of supply, and to convert hospitals from energy sinks to healthy and reliable energy resources.…”

The ambitious target of reaching net-zero greenhouse gas emissions by 2050 in the UK, which includes the decarbonisation of heat and electricity, means the increase of instantaneous power from non-dispatchable renewable energy sources (RESs). The intermittency of RESs will cause stability issues for the grid resulting from the mismatch between generation from RES and load demand. Battery energy storage systems (BESS) can match loads with generation and can provide flexibility to the grid. This study is proposing the health sector as a new flexibility services provider for the grid through BESS. The health sector has large loads that run throughout the year, and by managing this load it can provide flexibility to the grid. Four different scenarios have been evaluated for a range of behind-the-meter (BTM) BESS for a hospital in the UK to provide arbitrage and ancillary services considering the option of installing a photovoltaic (PV) system. It was found that BESS would not be economically viable through arbitrage alone since the payback period was always greater than the BESS lifetime. However, bundling services by participating in the ancillary services market resulted in payback periods as low as 3.10 years for some systems, and the net present value (NPV) could reach more than £5 million. This work provides evidence that the health sector can be a significant player in the transition to a renewables-led energy system, an exemplar for other sectors, and one of the solutions to recovery from the COVID19 pandemic.

“…The application of gas engines for the improvement of the energy supply to hospitals has a decade-long history in Hungary, with both successful and less successful solutions. In the present market environment, and based on the significant (both electric and heatside) energy demands of hospitals (Erdélyi, A., Pulay Gy., 2021), as well as the special distribution of this demand in time, a service package that offers a solution for the provision of essential, continuously available, reliable and quality energy supply (Elekes, A., 2018) may completely transform the present system of relations between hospitals and energy suppliers, creating an arrangement that is successful for both parties (Gurieff, N., Green, D., Koskinen, I., et al, 2020). Another reason why this research is particularly timely is the fact that the majority of the combined gas engine production units established for the KÁP/KÁT (mandatory takeover support, earlier KÁP) electricity sale, which was fairly widespread in the 2000s, have been technically fully amortised, moreover, the heat supply contracts of hospitals are close to expiry or already expired, and they are extended only temporarily with the present equipment and service provider.…”

In the research, we have developed an operational concept based on new energy generation devices, which, in addition to providing heat and electricity, guarantees uninterrupted supply locally and the sale of system services off-site. Based on international experience in the sector, the overall business concept needs to be developed for successful pilot projects. The trends in the technical-economic and regulatory environment examined show that the direction of change, with uncertain outcomes today, is unanimous: they all support the market penetration and the continued profitability of smallscale power plant devices suitable for secondary regulation. An important task is to identify unique elements in the value propositions. The aim of the research is to identify which of the factors such as realized price differential, heat-side revenues, generation utilization, optimized plant operation, scaling, etc. have an impact on the investment, operation, as well as the overall business model and profitability, and to what extent.
