Climate sustainability through a dynamic duo: Green hydrogen and crypto driving energy transition and decarbonization

Apoorv Lal, Fengqi You

Climate change persists as a pressing global issue due to high greenhouse gas emissions from fossil fuel-based energy sources. A transition to a greener energy matrix combined with carbon offsetting is imperative to mitigate the rate at which global temperature ascends. While countries have deployed faith in green hydrogen to accelerate worldwide decarbonization efforts, the concurrent rise of blockchain-operated crypto-applications, such as bitcoin, has exacerbated climate change concerns. In this study, we propose technological solutions that combine the green hydrogen infrastructure with bitcoin mining operations to catalyze environmental and socioeconomic sustainability in climate change mitigation strategies. Since the present state of crypto-operations undeniably contributes to worldwide carbon emissions, it becomes vital to explore opportunities for harnessing the widespread enthusiasm for bitcoin as an aid toward a sustainable and climate-friendly future. Our findings reveal that green hydrogen production, paired with crypto-operations, can accelerate the deployment of solar and wind power capacities to boost conventional mitigation frameworks. Specifically, leveraging the economic potential derived from green hydrogen and bitcoin for incremental investment in renewable energy penetration, this dynamic duo can enable capacity expansions of up to 25.5% and 73.2% for solar and wind power installations. Therefore, the proposed technological solutions that leverage green hydrogen and bitcoin mining, bolstered with appropriate policy interventions, can not only strengthen renewable power generation and carbon offsetting capacities but also contribute significantly to achieving climate sustainability.

The impact of digital financial inclusion on China's energy consumption: does economic decentralization matter?

Jiayu Zhou, Z. G. Liu

Based on China's provincial panel data from 2011 to 2020, this paper empirically analyzes the impact of digital financial inclusion(DFI) on regional energy consumption(ECI) using two-way fixed effects model, panel threshold effects model and instrumental variables regression. The results show that, firstly, DFI`s development has an obvious inhibitory effect on the intensity of regional energy consumption. Meanwhile, the heterogeneity analysis finds that there are obvious regional differences, differences in the degree of financial agglomeration and differences in their own dimensions in the inhibitory effect of DFI on regional energy consumption. Specifically, the energy-saving effect of digital finance is more obvious in the western region of China, in regions with a lower degree of financial agglomeration, and the strongest inhibitory effect is the breadth of digital inclusion coverage. In addition, the threshold effect analysis shows that the energy-saving effect of DFI not only increases with DFI`s development, but also exists in a non-linear pattern of significant "marginal increment" as the degree of economic decentralization increases. To this end, China should make greater efforts to develop DFI and optimize its industrial structure; formulate differentiated development policies that take into account the resource endowment, industrial structure and technological level of each region; and improve its macroeconomic governance system by taking into account the level of DFI`s development in the region, as well as the power of financial decision-making and financial management..

Overview of Energy Systems in Africa: A Comprehensive Review

Michael M. Santos, Ana Teresa Vaz Ferreira, JoĂŁo Lanzinha

Africa has abundant solar resources but only 2% of its current capacity is generated from renewable sources. Photovoltaics (PV) offer sustainable, decentralized electricity access to meet development needs. This review synthesizes the recent literature on PV in Africa, with a focus on Mozambique. The 10 most cited studies highlight the optimization of technical components, such as storage and bifacial modules, and challenges in integrating large-scale PV. Case studies demonstrated Mozambique’s potential for PV applications in water heating, irrigation, and rural electrification. These benefits include reduced emissions and energy access. However, barriers, such as high costs, lack of infrastructure, and training, exist. While solar cookers are insufficient, thermal systems have unrealized potential. Mozambique’s urban and rural electrification rates are 57% and 13%, respectively, despite its energy resources. Targeted policies, financing, and community engagement are essential for promoting adoption. While PV can sustainably expand electricity access, coordinated efforts must address costs, infrastructure, maintenance, and social factors for successful implementation. Mozambique has immense solar potential, but strategic planning and support are critical to unlocking these benefits. This review provides insights into optimizing PV systems and policy frameworks for a clean and inclusive energy production future in Africa, to synthesize the 10 most cited studies on photovoltaic solar energy in Africa, and to deeply reflect upon the current energy needs in Mozambique, the benefits of employing PV and solar thermal systems, and the challenges of implementing such systems within the Mozambican context.

The Hidden Environmental Cost of Cryptocurrency: How Bitcoin Mining Impacts Climate, Water and Land

Sanaz Chamanara, Kaveh Madani

Based on a multi-attribute assessment of the environmental impacts and challenges associated with global Bitcoin (BTC) mining activities around the globe, we call for urgent action by the scientific, policy, and advocacy communities. The worldwide BTC mining network consumed 173.42 TWh of electricity during the 2020–2021 period, bigger than the electricity consumption of most nations. The mining process emitted over 85.89 Mt of CO2eq in the same timeframe, equivalent to the emission caused by burning 84 billion pounds of coal or running 190 natural gas-fired power plants. The environmental footprint of BTC mining is not limited to greenhouse gas emissions. In 2020–2021, the global water footprint of BTC mining was about 1.65 km 3, more than the domestic water use of 300 million people in rural Sub-Saharan Africa. The land footprint of the global BTC mining network during this period was more than 1,870 square kilometers, 1.4 times the area of Los Angeles. These striking numbers highlight the heavy reliance of the BTC network on fossil fuels and natural resource-intensive energy sources, resulting in major but unmonitored and unregulated environmental footprints. To mitigate the environmental costs of BTC mining, immediate policy interventions, technological advancements, and scientific research are crucial. Proposed measures include enhanced transparency, economic and regulatory tools, developing energy-efficient alternative coins, and the adoption of greener blockchain validation protocols.

The Environmental Footprint of Bitcoin Mining Across the Globe: Call for Urgent Action

Sanaz Chamanara, S. Arman Ghaffarizadeh, Kaveh Madani

Abstract Based on a multi‐attribute assessment of the environmental impacts and challenges associated with global Bitcoin (BTC) mining activities around the globe, we call for urgent action by the scientific, policy, and advocacy communities. The worldwide BTC mining network consumed 173.42 TWh of electricity during the 2020–2021 period, bigger than the electricity consumption of most nations. The mining process emitted over 85.89 Mt of CO 2 eq in the same timeframe, equivalent to the emission caused by burning 84 billion pounds of coal or running 190 natural gas‐fired power plants. The environmental footprint of BTC mining is not limited to greenhouse gas emissions. In 2020–2021, the global water footprint of BTC mining was about 1.65 km 3 , more than the domestic water use of 300 million people in rural Sub‐Saharan Africa. The land footprint of the global BTC mining network during this period was more than 1,870 square kilometers, 1.4 times the area of Los Angeles. These striking numbers highlight the heavy reliance of the BTC network on fossil fuels and natural resource‐intensive energy sources, resulting in major but unmonitored and unregulated environmental footprints. To mitigate the environmental costs of BTC mining, immediate policy interventions, technological advancements, and scientific research are crucial. Proposed measures include enhanced transparency, economic and regulatory tools, developing energy‐efficient alternative coins, and the adoption of greener blockchain validation protocols.

Decentralized solar-powered cooling systems for fresh fruit and vegetables to reduce post-harvest losses in developing regions: a review

Waseem Amjad, Anjum Munir, Fatima Akram, Aditya Parmar ¡ 7 authors

Abstract The availability of on-farm storage and processing is a critical challenge facing small farmers, which hinders agricultural productivity. Thirty per cent of the food produced globally is lost after harvest, with the proportion being exceptionally high in low- and middle-income countries due to a lack of on-farm handling and storage facilities. Conventional cold-storage solutions have not taken off at the smallholder level, mainly due to a lack of availability and access to reliable grid electricity. Therefore, off-grid decentralized solar-powered cold-storage units can play a vital role in preserving the produce at production sites and enhancing livelihood and rural development with a minimal carbon footprint. To maintain low temperatures at every step of the agricultural value chain, known as the ‘cold chain’, several technology vendors aim to improve the shelf life and user benefit. Small-scale farmers, which account for two-thirds of all food losses, are another group they focus on. This study examines the existing situation, importance and potential opportunities of decentralized cold-storage systems for fresh fruit and vegetables. In addition to economic, social, technological and environmental limitations, this study examines the triumphs and challenges of incorporating solar-energy-powered cold storage into developing communities. Although the private sector, NGOs and some government agencies are working to promote decentralized cold-storage facilities, relatively little has been done so far to have a significant influence on post-harvest losses and food security. There are still knowledge gaps on decentralized cold-storage facilities. The primary operational constraint is the economic situation of end users and the lack of financing alternatives for smallholder farmers.

A Multi-Stakeholder Governance Model for Decentralized Energy Access in Rural Communities

Mohammed Lawal Giwah, Zamathula Queen Sikhakhane Nwokediegwu, Emmanuel Augustine Etukudoh, Ebimor Yinka Gbabo

Decentralized energy systems are increasingly recognized as a viable solution for extending electricity access to rural communities underserved by traditional grid infrastructure. However, their sustainability and scalability are often compromised by fragmented governance, limited community participation, and weak institutional coordination. This paper proposes a comprehensive multi-stakeholder governance model tailored to the complexities of decentralized energy delivery in rural contexts. Grounded in governance theory and stakeholder analysis, the model emphasizes five core principles: inclusivity, transparency, accountability, subsidiarity, and resilience. It clearly delineates the roles of government actors, private sector players, communities, and non-governmental organizations, and establishes mechanisms for collaborative decision-making, financial alignment, and adaptive oversight. The paper also explores policy and implementation considerations, including regulatory harmonization, blended financing strategies, and capacity building for local stakeholders. By addressing the institutional gaps that hinder rural electrification efforts, the proposed model contributes both theoretically to energy governance literature and practically to policy design and implementation. It offers a scalable, equitable framework that embeds trust, coordination, and long-term sustainability into decentralized energy transitions.

Techno-Economic Evaluation of Hydrogen-Based Cooking Solutions in Remote African Communities—The Case of Kenya

Nikolas SchĂśne, Raluca Dumitrescu, Boris Heinz

Hydrogen has recently been proposed as a versatile energy carrier to contribute to archiving universal access to clean cooking. In hard-to-reach rural settings, decentralized produced hydrogen may be utilized (i) as a clean fuel via direct combustion in pure gaseous form or blended with Liquid Petroleum Gas (LPG), or (ii) via power-to-hydrogen-to-power (P2H2P) to serve electric cooking (e-cooking) appliances. Here, we present the first techno-economic evaluation of hydrogen-based cooking solutions. We apply mathematical optimization via energy system modeling to assess the minimal cost configuration of each respective energy system on technical and economic measures under present and future parameters. We further compare the potential costs of cooking for the end user with the costs of cooking with traditional fuels. Today, P2H2P-based e-cooking and production of hydrogen for utilization via combustion integrated into the electricity supply system have almost equal energy system costs to simultaneously satisfy the cooking and electricity needs of the isolated rural Kenyan village studied. P2H2P-based e-cooking might become advantageous in the near future when improving the energy efficiency of e-cooking appliances. The economic efficiency of producing hydrogen for utilization by end users via combustion benefits from integrating the water electrolysis into the electricity supply system. More efficient and cheaper hydrogen technologies expected by 2050 may improve the economic performance of integrated hydrogen production and utilization via combustion to be competitive with P2H2P-based e-cooking. The monthly costs of cooking per household may be lower than the traditional use of firewood and charcoal even today when applying the current life-line tariff for the electricity consumed or utilizing hydrogen via combustion. Driven by likely future technological improvements and the expected increase in traditional and fossil fuel prices, any hydrogen-based cooking pathway may be cheaper for end users than using charcoal and firewood by 2030, and LPG by 2040. The results suggest that providing clean cooking in rural villages could economically and environmentally benefit from utilizing hydrogen. However, facing the complexity of clean cooking projects, we emphasize the importance of embedding the results of our techno-economic analysis in holistic energy delivery models. We propose useful starting points for future aspects to be investigated in the discussion section, including business and financing models.

An Adaptive Staggered Investment Strategy for promotion of residential rooftop solar PV installations in India

Anu G Kumar, M R Sindhu, Vivek Mohan, Rekha Viswanathan ¡ 5 authors

Rooftop solar PV in India has seen good progress in the Commercial and industrial sectors, but the progress in the domestic sector is relatively slow due to the high initial installation cost. Thus, there arises the need for good market models for Rooftop Solar (RTS) implementation. This paper conducts a comparative study of workable RTS market models by employing the discounted cash flow method, as per the recent regulatory guidelines. Market models are formulated and tested for a typical residential high-rise apartment complex in India comprising 15 storied buildings with a combined maximum demand of 180kVA. The results suggest that the centralized community RTS model of 80kWp capacity with upfront financing is suitable when compared to the decentralized individual model, as it has the lowest levelized cost of 3.39 ₹/kWh and a payback period of 5.5 years. With the federal subsidy, the prosumer levelized cost reduces to 2.06 ₹/kWh with a payback period of 3.3 years. Thus grid parity is achieved for all tariff tier rates. With adaptive staggering strategy, this scheme is validated to be more attractive for the urban residential microgrids, as the solar installation of 80kWp and its cost can be staggered and even reduced over the planning period. Hence capital installation and operation costs can be distributed over the stipulated time interval. The study result gives RTS stakeholders insight into selecting the most cost-effective market model to suit their requirements. Financial analysis of the proposed models provides input to the customers, developers, and policymakers to assess the financial merit of adopting the suitable business model for RTS development. The proposed analysis can be replicated for high-rise residential buildings, especially in cities with high electricity tariffs. With time, a decrease in solar PV installation price and an increase in grid price are expected; hence, the overall investment cost gets reduced and staggered.

Can green finance improve China's haze pollution reduction? The role of energy efficiency

Hao Zhang, Ye Duan, Jun Yang, Han Zeng-lin ¡ 5 authors

Green finance is crucial to advancing the decrease of haze pollution in my nation as a new kind of environmental governance. This research constructs a comprehensive evaluation system of green finance to analyze the impact of green finance on haze pollution reduction and to consider the mediating role of energy efficiency in 30 provinces and regions in China. Through a series of robustness tests, the mechanism and path of green finance on haze pollution reduction are confirmed. The main conclusions are as follows: First, the development of green finance has a positive effect on haze pollution reduction. Second, the upgrading of industrial structure and the improvement of technological level are important paths for green finance to promote haze pollution reduction, and can also have an indirect impact through energy efficiency. The moderating and mediating effects of energy efficiency and green finance can effectively promote the reduction of haze pollution. In other words, the development of green finance can achieve the goal of reducing haze pollution by improving energy efficiency. Third, there is regional heterogeneity in green finance for haze pollution reduction, and regions with high levels of green finance are more effective in reducing haze pollution. Fourth, environmental Supervision, environmental decentralization and average wind speed can promote haze pollution reduction, economic development to some extent exacerbated the haze pollution. Based on the above research conclusions, this paper puts forward corresponding countermeasures and suggestions.

A review of renewable off-grid mini-grids in Sub-Saharan Africa

Oluleke Babayomi, Babatunde Olubayo, Iheanacho H. Denwigwe, Tobiloba Somefun ¡ 8 authors

Sub-Saharan Africa (SSA) is home to 75% of the world’s unelectrified population, and approximately 500 million of these live in rural areas. Off-grid mini-grids are being deployed on a large scale to address the region’s electrification inequalities. This study aims to provide a comprehensive review of the research on the off-grid renewable mini-grids in SSA. The study covers the current status of the level of deployment of off-grid mini-grids. It also reviews multi-criteria decision-making models for optimizing engineering, economics, and management interests in mini-grid siting and design in SSA. The statuses of financing, policy, and tariffs for mini-grids in SSA are also studied. Finally, the current status of energy justice research in respect of mini-grids in SSA is reviewed. The study shows the important role of decentralized renewable technologies in the electrification of SSA’s rural population. Within a decade since 2010, the rural electrification rate of SSA has increased from 17% to 28%, and 11 million mini-grid connections are currently operational. Despite these gains, the literature points to several injustices related to the present model by which SSA’s renewable mini-grids are funded, deployed, and operated. Hence, several recommendations are provided for the effective application of the energy justice framework (EJF) for just and equitable mini-grids in SSA.

100 Important Questions about Bitcoin’s Energy Use and ESG Impacts

Murray A. Rudd

Bitcoin critics have argued that energy-intensive Bitcoin production and adoption will exacerbate global warming. Conversely, Bitcoin advocates have been dismayed by critics’ apparent lack of willingness to scrutinize Bitcoin’s potential role in helping to improve the economics of renewable energy investments, reduce net emissions from methane venting and flaring, increase electricity grid efficiency, and provide higher-order environmental, social, and governance (ESG) benefits. Given the disparate views, there is a pressing need to identify key knowledge needs regarding Bitcoin’s net energy use, carbon emissions, and direct and indirect ESG impacts. I used a variation on the ‘key questions’ horizon scanning approach to identify 100 questions that, if answered, could help provide credible evidence to support policymakers’, investors’, and research funders’ decision-making on issues relating to the impact of Bitcoin production and adoption. The questions are distributed across 13 themes (ranging from energy use to social impacts). The breadth of knowledge required to answer key questions highlights the need to build research capacity, encourage collaborative cross-sectoral and -disciplinary research, and develop a prioritized research agenda. Defensible evidence for investors, regulators, and policymakers needs to consider Bitcoin’s complex net impacts on energy use and environmental, social, and governance benefits.

Decentralized Electrification Pathways in Sub-Saharan Africa—Assessment of Experiences and Business Models

George Arende, Sofia Gonçalves

Abstract The transition to “SDG7 -modern and sustainable energy for all” may reconfigure the lives of citizens who live “outside the grid” in the rural communities in sub-Saharan Africa. The decentralization approach for developing renewable energy in sub-Saharan Africa has constantly been promoted as a means to rural electrification. This paper reviews the barriers to private sector participation in decentralized electrification projects and the solutions that have been proposed and implemented. It is not only the economic approaches that are analysed but also some of the solutions or drivers that have contributed to rural electrification. There are specific technological pathways which have proven fruitful in sub-Saharan Africa that are unique to its economic and demographic settings and that otherwise would not be adopted or used in developed countries. This paper finally analyses these technological pathways with the objective of matching the drivers and obstacles to potential solutions. Long term energy planning with the integration of regional power pools is instrumental to reduce CAPEX as well as to increase the market size. Blended financing together with already working technologies such as pay-as-you-go, and mobile money will be the pillars to meeting SDG7 goals.

A mini-review of practical interventions of renewable energy for climate change in Sub-Saharan Africa in the last decade (2010–2020): implications and perspectives

Jean Mulopo

As part of the Kyoto Protocol, several Sub-Saharan Africa countries vowed to use more renewable energy sources, and the number of Sub-Saharan Africa countries that have undertaken renewable energy initiatives has expanded considerably over the preceding decade. However, assuring demand while reducing climate change has always been one of the most significant difficulties confronting the global energy sector. This review looks at the state of practical renewable energy interventions in Sub-Saharan Africa countries over the last decade (2010-2020), focusing on infrastructure development and accessibility, decentralization, distribution, and communal acceptance, donor funding and private sector involvement, and the role of state political influence in renewable energy strategies. This study's findings suggest that renewable energy interventions in Sub-Saharan Africa are based on mature and commercialized technologies, that natural resources for energy generation have not been fully explored, and that ongoing research and development on raw material or feedstock availability will benefit regional and national projects. The findings also show that off-grid technology interventions exist in Sub-Saharan Africa. However, the adoption of a decentralized approach to renewable energy generation, particularly in rural areas, financing, and the need for integrated project design and implementation, which includes factors such as community mobilization, social, economic, institutional, and technical engagement, have all hampered the implementation of such technologies.

A comparative analysis of biogas and hydrogen, and the impact of the certificates and blockchain new paradigms

Karen Mould, Fábio Silva, S. Knott, Brian O’Regan

Solar and wind energy technologies, due to their nature of weather dependency, have been recognized as not the complete solution for the renewable energy transition. Creating a solution for the short fall is empirical if we are to remove the dependency on fossil fuels and reach net zero targets. The production of hydrogen, biogas and other gases can be produced sustainably, which can also allow for the utilization of waste materials or the ability to store energy and allow a greater positive impact on our environment. However, production of these gases is not always as transparent or environmentally friendly as perceived, so with the aid of certification and blockchain, we can create a system that can guarantee their environmentally positive origin, and ultimately help assist the transition to a greener future. This paper explores the varying production methods, with consideration to their environmental impact, and the implications of the use of certificates and blockchain to monitor production, trade and usage.

Rural electrification subsidy estimation: a spatial model development and case study

Lefu Maqelepo, Nathaniel J. Williams, Jay Taneja

Abstract A global push to achieve universal electricity access, paired with drastic reductions in the cost of decentralized electricity technologies, has led to significant research on how best to roll out access to rural communities in sub-Saharan Africa. Various geospatial electrification models have been developed to aid the decision-making process considering decentralized grid alternatives such as mini-grids and solar home systems. Despite these tools suggesting that in many cases, decentralized systems are a more cost-effective electricity access pathway, grid extension still predominates in practice. This is due, at least in part, to institutional structures in most countries that provide significant direct and indirect subsidies to grid extension projects, commonly through publicly-owned utilities. These sources of finance are generally not available to primarily privately operated off-grid energy service providers. However, the subsidy provided for grid extension projects is not well understood. In this paper, we employ utility grid extension costs and revenue data, and geospatial grid infrastructure data to estimate the size and distribution of subsidy implicitly provided to rural grid extension projects for 129 communities in Mombasa County, Kenya. We also estimate subsidies for hypothetical off-grid electricity systems in the same communities that would deliver equivalent services to the grid. We allocate the cost of shared medium voltage (MV) distribution infrastructure using a marginal and an average cost method for grid extension and compare these with subsidies for off-grid systems. We find that the average of average subsidy per customer across communities for grid extension is US$5,118 and US$5,330 for the two MV cost allocation methods respectively, while for the off-grid systems the corresponding average of average subsidies are US$3,380, using a real discount rate of 1.3% evaluated from a nominal discount rate of 8% and inflation rate of 6.7%. Our results show that in the communities in our case study, 40% and 37% of the communities would command less subsidy while served by minigrids over the grid, and the switch would save 50% and 54% of the total cost for average and marginal cost allocation methods respectively. We also show that by using a multi-model approach to electrification and by reallocation of implicit subsidies that have been exclusive to grid extension to other technology options utilities can cast the net wider, without an increase in budgets.
