Climate Neutrality

In December 2019, the European Commission unveiled an ambitious project, the European Green Deal, which aims to lead the European Union to climate neutrality by 2050. This is a significant challenge for all EU countries, and especially for Poland. The role of hydrogen in the processes of decarbonization of the economy and transport is being discussed in many countries around the world to find rational solutions to this difficult and complex problem. There is an ongoing discussion about the hydrogen economy, which covers the production of hydrogen, its storage, transport, and conversion to the desired forms of energy, primarily electricity, mechanical energy, and new fuels. The development of the hydrogen economy can significantly support the achievement of climate neutrality. The belief that hydrogen plays an important role in the transformation of the energy sector is widespread. There are many technical and economic challenges, as well as legal and logistical barriers to deal with in the transition process. The development of hydrogen technologies and a global sustainable energy system that uses hydrogen offers a real opportunity to solve the challenges facing the global energy industry: meeting the need for clean fuels, increasing the efficiency of fuel and energy production, and significantly reducing greenhouse gas emissions. The paper provides an in-depth analysis of the Polish Hydrogen Strategy, a document that sets out the directions for the development of hydrogen use (competences and technologies) in the energy, transport, and industrial sectors. This analysis is presented against the background of the European Commission’s document ‘A Hydrogen Strategy for a Climate-Neutral Europe’. The draft project presented is a good basis for further discussion on the directions of development of the Polish economy. The Polish Hydrogen Strategy, although it was created later than the EU document, does not fully follow its guidelines. The directions for further work on the hydrogen strategy are indicated so that its final version can become a driving force for the development of the country’s economy.

Climate Neutrality

This paper contributes to the climate policy discussion by focusing on the challenges and opportunities of reaching net zero emissions by 2050 in Italy. To support Italian energy planning, we developed energy roadmaps towards national climate neutrality, consistent with the Paris Agreement objectives and the IPCC goal of limiting the increase in global surface temperature to 1.5 °C. Starting from the Italian framework, these scenarios identify the correlations among the main pillars for the change of the energy paradigm towards net emissions by 2050. The energy scenarios were developed using TIMES-RSE, a partial equilibrium and technology-rich optimization model of the entire Italian energy system. Subsequently, an in-depth analysis was developed with the sMTISIM, a long-term simulator of power system and electricity markets. The results show that, to achieve climate neutrality by 2050, the Italian energy system will have to experience profound transformations on multiple and strongly related dimensions. A predominantly renewable-based energy mix (at least 80–90% by 2050) is essential to decarbonize most of the final energy consumption. However, the strong increase of non-programmable renewable sources requires particular attention to new flexibility resources needed for the power system, such as Power-to-X. The green fuels produced from renewables via Power-to-X will be a vital energy source for those sectors where electrification faces technical and economic barriers. The paper’s findings also confirm that the European “energy efficiency first” principle represents the very first step on the road to climate neutrality.

The article is devoted to the subject of the goals of the climate and energy policy of the European Union, which can have both a positive, and a negative impact on the environmental and energy policies. Positive aspects are the reduction of greenhouse gas emissions, diversification of energy supplies, which should improve Europe independence from energy imports, and increasing the share of renewable energy sources (RES) in the national energy system structures. On the other hand, overly ambitious targets and actions can lead to large losses for the economies of EU Member States. The article also highlights the realities prevailing in the international arena and noncompliance of international actors with global agreements on climate protection.

Nowadays, energy security is a growing concern in state foreignpolicy. Interdependency in the energy field is a very important dimensionof contemporary relations between states and transnational corporations.Energy security is becoming a key issue for the European Union (EU). TheUnion is one of the world’s fastest-growing energy markets and the biggestimporter of energy resources. For the foreseeable future, Europe’s energydependence will probably increase. Facing a shortage of energy, Europe isdependent on imports and the EU member states need to diversify their energysupplies. The Caspian region contains some of the largest undevelopedoil and gas reserves in the world. After the collapse of the Soviet Union, thenewly independent Caspian states became open to foreign investment. Thegrowing energy needs have given the EU a strong interest in developing tieswith energy-producing states in the Caspian region to build the necessarypipeline infrastructure. In this analysis, the pipeline infrastructure that exists orwill be built in the near future will be presented. The analysis will concentrateon routes transporting gas from the Caspian region and the most importantproblems and solutions in designing the midstream energy system in the region.The key aim of the article is to analyse the Southern Gas Corridor (SGC)infrastructure project, which will inevitably contribute to the EU’s energy securityinterest.

A hydrogen energy system will require the production of hydrogen from coal-based gasification plants and its transmission through long distance pipelines at 70 � 100 bar. To overcome some problems of current gasifiers, which are limited in pressure capability, two options are explored, in-plant compression of the syngas and compression of the hydrogen at the plant exit. It is shown that whereas in-plant compression using centrifugal machines is practical, this is not a solution when compressing hydrogen at the plant exit. This is because of the low molecular weight of the hydrogen. It is also shown that if centrifugal compressors are to be used in a pipeline system, pressure drops will need to be restricted as even an advanced two-stage centrifugal compressor will be limited to a pressure ratio of 1.2. High strength steels are suitable for the in-plant compressor, but aluminium alloy will be required for a hydrogen pipeline compressor.

Climate Neutrality

Global trade of green hydrogen will probably become a vital factor in reaching climate neutrality. The sunbelt of the Earth has a great potential for large-scale hydrogen production. One promising pathway to solar hydrogen is to use economically priced electricity from photovoltaics (PV) for electrochemical water splitting. However, storing electricity with batteries is still expensive and without storage only a small operating capacity of electrolyser systems can be reached. Combining PV with concentrated solar power (CSP) and thermal energy storage (TES) seems a good pathway to reach more electrolyser full load hours and thereby lower levelized costs of hydrogen (LCOH). This work introduces an energy system model for finding cost-optimal designs of such PV/CSP hybrid hydrogen production plants based on a global optimization algorithm. The model includes an operational strategy which improves the interplay between PV and CSP part, allowing also to store PV surplus electricity as heat. An exemplary study for stand-alone hydrogen production with an alkaline electrolyser (AEL) system is carried out. Three different locations with different solar resources are considered, regarding the total installed costs (TIC) to obtain realistic LCOH values. The study shows that a combination of PV and CSP is an auspicious concept for large-scale solar hydrogen production, leading to lower costs than using one of the technologies on its own. For today’s PV and CSP costs, minimum levelized costs of hydrogen of 4.04 USD/kg were determined for a plant located in Ouarzazate (Morocco). Considering the foreseen decrease in PV and CSP costs until 2030, cuts the LCOH to 3.09 USD/kg while still a combination of PV and CSP is the most economic system.

Considering the European Union (EU) climate targets, the heating sector should be decarbonized by 80 to 95% up to 2050. Thus, the macro-trends forecast increasing energy efficiency and focus on the use of renewable gas or the electrification of heat generation. This has implications for the business models of urban electricity and in particular natural gas distribution network operators (DNOs): When the energy demand decreases, a disproportionately long grid is operated, which can cause a rise of grid charges and thus the gas price. This creates a situation in which a self-reinforcing feedback loop starts, which increases the risk of gas grid defection. We present a mixed integer linear optimization model to analyze the interdependencies between the electricity and gas DNOs’ and the building owners’ investment decisions during the transformation path. The results of the investigation in a real grid area are used to validate the simulation setup of a sensitivity analysis of 27 types of building collectives and five grid topologies, which provides a systematic insight into the interrelated system. Therefore, it is possible to identify building and grid configurations that increase the risk of a complete gas grid shutdown and those that should be operated as a flexibility option in a future renewable energy system.

Hybrid Renewable Energy

The use of multi sources systems of energy progressed significantly in different industrial sectors. Between all the existing sources of energy, batteries and renewable sources, such as photovoltaic and wind, contain the highest specified energy. However, solar and wind energies are not available all the time, their performance is affected by unpredictable weather changes and therefore, it is difficult to control as it is not always feasible to obtain an accurate mathematical model of the controlled system. Also, uncertainty of the wind power can affect system stability. This paper presents a computer algorithm based on fuzzy logic control (FLC) to estimate the wind and solar energies in a hybrid renewable energy system from natural factors. The wind power was estimated using the wind speed as an input parameter and the solar power was estimated using the temperature and the lighting as input parameters.

The Green Deal of the European Union defines extremely ambitious climate targets for 2030 (−55% emissions compared to 1990) and 2050 (−100%), which go far beyond the current goals that the EU member states have agreed on thus far. The question of which sectors contribute how much has already been discussed, but is far from decided, while the question of which countries shoulder how much of the tightened reduction targets has hardly been discussed. We want to contribute significantly to answering these policy questions by analysing the necessary burden sharing within the EU from both an energy system and an overall macroeconomic perspective. For this purpose, we use the energy system model TIMES PanEU and the computational general equilibrium model NEWAGE. Our results show that excessively strong targets for the Emission Trading System (ETS) in 2030 are not system-optimal for achieving the 55% overall target, reductions should be made in such a way that an emissions budget ratio of 39 (ETS sector) to 61 (Non-ETS sector) results. Economically weaker regions would have to reduce their CO2 emissions until 2030 by up to 33% on top of the currently decided targets in the Effort Sharing Regulation, which leads to higher energy system costs as well as losses in gross domestic product (GDP). Depending on the policy scenario applied, GDP losses in the range of −0.79% and −1.95% relative to baseline can be found for single EU regions. In the long-term, an equally strict mitigation regime for all countries in 2050 is not optimal from a system perspective; total system costs would be higher by 1.5%. Instead, some countries should generate negative net emissions to compensate for non-mitigable residual emissions from other countries.

Hydrogen is receiving increasing attention for achieving carbon abatement in various sectors, including transport, logistics, thermal engineering and industrial feedstock, etc. Hydrogen can also support distributed power supply that raises national energy security. Both commercial and industrial sectors share a common vision that increasing the cost-effectiveness of renewable hydrogen represents their strategic achievement towards substantial sustainability. This paper explains how hydrogen can play seven roles in the energy transition which include large-scale integration of renewable energy into the power grid, medium for storing and distributing energy across sectors and/or regions, a buffer to increase the electric system resilience and clean fuel for fuel cell vehicles to decarbonise transport. Besides, hydrogen can decarbonise building energy consumption and serve as feedstock using captured carbon. Power Assets Holdings Limited (PAH), a global investor in energy and utility-related business, has identified a hydrogen economy as a strategic vision in its business plan for zero carbon readiness in 2035 and a carbon-free business model in 2050. In this paper, the features and attributes of different hydrogen projects, such as H21 and InTEGRel in the UK and Hydrogen Park in South Australia, are discussed to demonstrate the commercial deployment of hydrogen power.
