“…Consumers will be able to choose a low carbon energy source that best fits their needs and what may be more suitable in their area or for their socioeconomic status. Sector coupling with hydrogen energy allows for an increased integration of energy end-use and multiple supply sectors (He et al, 2021;Travers, 2021). This allows for an increased efficiency and flexibility of a hydrogen economy, as well as working with electrification to reduce the cost of decarbonization (Van Nuffel, 2018).…”

In recent years, there has been an increased interest in hydrogen energy due to a desire to reduce greenhouse gas emissions by utilizing hydrogen for numerous applications. Some countries (e.g., Japan, Iceland, and parts of Europe) have made great strides in the advancement of hydrogen generation and utilization. However, in the United States, there remains significant reservation and public uncertainty on the use and integration of hydrogen into the energy ecosystem. Massachusetts, similar to many other states and small countries, faces technical, infrastructure, policy, safety, and acceptance challenges with regards to hydrogen production and utilization. A hydrogen economy has the potential to provide economic benefits, a reduction in greenhouse gas emissions, and sector coupling to provide a resilient energy grid. In this paper, the issues associated with integrating hydrogen into Massachusetts and other similar states or regions are studied to determine which hydrogen applications have the most potential, understand the technical and integration challenges, and identify how a hydrogen energy economy may be beneficial. Additionally, hydrogen’s safety concerns and possible contribution to greenhouse gas emissions are also reviewed. Ultimately, a set of eight recommendations is made to guide the Commonwealth’s consideration of hydrogen as a key component of its policies on carbon emissions and energy.

“…Energy sector decarbonization is a very complex issue where many political, environmental, economic, social, and ethical aspects should be considered all together (Papadis & Tsatsaronis, 2020;Watari et al, 2021). However, the ratio cost -efficiency in emission reduction could influence energy industry in production technologies associated with the full supply chains involved (Speirs et al, 2018;Parkinson et al, 2019), so it is importance to develop an integrated energy system framework with multiple energy drivers in providing cost-effective energy system decarbonization (He et al, 2021).…”

We live demanding times and after two pandemic years the energy prices are rising worldwide. The world is hungry for energy and climate change calls for lower emissions. The major power energy sector challenges are the increased energy demand due to industrial activity, climate change, demographic pressures, and urbanization trends, including pandemic. The companies need efficient and reliable energy and decarbonization technologies to succeed. Industries and power generation companies had to take on many challenges while running their business operations. However, the process of decarbonization takes time and includes the energy transition away from conventional fuels, from coal to gas and then to hybrid systems with renewables and cleaner fuels, such as hydrogen. The aim of this paper is to set a basis to pinpoint the subject of “Supply chains Decarbonization” within the Power energy sector as one of the tough challenges yet to come. The main objective of this article research is to provide a critical review of the commitments for decarbonization of supply-chains with focus on the power energy sector, based on international business experts and research articles. The methodologies used for this research is based on very recent research papers and studies review of major consulting groups, publishers, and energy sustainability councils. Pros and cons hypotheses are being organized as Highlights/ Lowlights over long or short run, in the conjecture of various consulting experts. The findings reveal that consulting groups express concerns and attention for the risks, some of the risks could be significant, results are less to be noted in the short run, but the results and the achievements are to be considered in the longer period. Google trend shows that the syntagms of “decarbonization” and “energy transition” are well known and searched.

“…We incorporate these storage technologies and their interactions, within the previously developed framework for electricity-H 2 infrastructure modeling, Decision Optimization for Low-carbon Power and Hydrogen Networks (DOLPHyN). 17 To properly model the operational attributes of LH2 and LOHC, we update the model to (a) account for the energetics and cost associated with possible state transitions of H 2 , resulting from adding these storage technologies into the supply chain and (b) introduce linking constraints across representative periods of hourly system operation to enable their possible use for long-term storage of energy. As a case study, the updated DOLPHyN model is applied to the study system outcomes for the U.S. Northeast region, where ambitious policies on deep decarbonization by mid-century have to contend with regional resource availability 18,33 (e.g., low-quality solar) and high spatial concentration of energy demand.…”

Hydrogen can be valuable for deep decarbonization of electricity systems as well as energy end-uses where direct electricity is challenged. While most hydrogen supply chain analyses focus on storing hydrogen as compressed gas hydrogen (CGH 2 ) storage, hydrogen storage systems with lower capital cost of storage capacity such as liquefied hydrogen (LH 2 ) and liquid organic hydrogen carriers (LOHC) may provide a differentiated value for energy system decarbonization. However, the latter systems have disadvantages (e.g., higher capital cost of charge/ discharge capacity, boil-off, high energy requirement for conversion/ reconversion) that could impede their deployment. In this study, we expand upon a previously developed electricity-hydrogen infrastructure planning model, DOLPHyN, to explore the value of liquid hydrogen solutions for energy storage and transport in a deeply decarbonized energy system. First, we show that TOL-LOHC (i.e., toluene-based LOHC) and LH 2 are beneficial as seasonal energy storage systems, while CGH 2 is more suitable for shorter-duration storage (e.g., weekly) cycling. The addition of LH 2 and LOHC enables more efficient utilization of deployed electric generation and power-to-hydrogen generation infrastructures. Second, we show that LH 2 is more favorable than LOHC for providing long-term storage for the power sector because its primary capital costs and energy penalty for conversion are incurred during charging periods, which typically correspond to when renewable energy is more abundant. Cost effectiveness of LH 2 is based on accounting for boil-off rates of largescale LH 2 systems. Third, we show that commercial viability of LOHC is strongly tied to the ability to lower the energetic consumption of the dehydrogenation process as well as its capital cost.
