How we think about the future of the pipe industry must evolve. How must tubular design and manufacturing change as we transition to clean energy? Geothermal energy is an area that needs attention and, further, needs very specific attention on tubulars. Tubulars are an important component in the construction of geothermal wells, and we must align our requirements for geothermal energy. Some of the main challenges encountered in geothermal wells are corrosion and scaling. Moreover, temperature becomes a major consideration for tubulars, even more so with the temperature excursion during geothermal production. Perhaps the critical aspect in the design of the geothermal wells involves casing selection and design. Beyond manufacturing casing pipes to withstand these problems, considering the manufacturing of other components, such as connections, float collars, and float shoes, also is essential. Thermal expansion and thermal excursion of casings are well-integrity concerns; thus, casing design is important for long-term sustainability of geothermal wells. Apart from thermal simulations, guidelines and software are needed to undergird the designs to withstand not only temperature excursions but also thermomechanical and thermochemical loadings. Engineered nonmetallic casings also provide an alternative solution because they provide the desired strength and corrosion resistance in addition to meeting the goals of sustainability. Undoubtedly, the future of the tubular industry is going to be revitalized. The question now is how we can retrofit existing abandoned wells for this purpose.

In 2024, all commercial operations at the Pickering Nuclear Generation Station cease and the station will begin its decommissioning process. Ontario Power Generation is currently looking developing a repurposing strategy for the site throughout the decommissioning process, which is expected to be complete by 2064. This project presents a unique opportunity to re-imagine the future of this site, while setting a precedent for the reuse of nuclear sites and facilities once they have reached the end of their life cycle – an issue that will be more prevalent in the coming years. This project proposes a vision for the site to be transformed into parkland using ecological restoration practices, and establishing a Centre for Clean Energy Technology. Using design as a form of research, the project was informed by background research that included a review of existing literature on post-industrial site redevelopment, precedent studies, and site reconnaissance.

South Africa has long recognised the need to eliminate energy poverty, and significant progress has been made since 1996. With the recent global outcry about the use of sustainable and clean energy sources for human and ecological development, it has become essential for countries to upscale the use of non-grid electrification in order to effectively and sustainably eradicate energy poverty. South Africa implements different non-grid electrification programmes which focuses on ensuring universal access to clean energy by all, with one of these initiatives being the Solar Home Systems Programme. This study aims to contribute to academic discussion and knowledge about the role that solar home systems can play in bringing change on the current status of the energy poverty eradication initiatives which negatively affect the environment and the people. The study used a qualitative approach in assessing how the Solar Home Systems Programme contributes to energy poverty eradication and environmental preservation if managed in line with ecological governance principles. Semi-structured interviews were conducted with a total of 40 households in Limpopo and officials from government departments in the province as well as a service provider responsible for the roll-out and maintenance of solar home systems in Limpopo. Framed within the ecological economics theory which advocates for ecological and environmental solutions that take into consideration the future generation, the study established that the solar home systems can eradicate energy poverty and contribute to the protection of the environment if managed in line with ecological governance principles. The study further revealed that the Solar Home Systems Programme in South Africa failed due to lack of proper governance systems that provide solutions for the future as the programme was short-term focused and lacked proper ecological governance systems. In order for the solar home systems to contribute to energy poverty eradication and environmental protection, the study recommends a total overhaul of the programme which includes ensuring that the provision of SHSs is not viewed as a temporary measure that is only meant for poor rural households but a long-term and sustainable initiative.

The Future

As we enter the new century, new fuels may be required for both stationary power and transportation to ameliorate the triple threats of local air pollution, global climate change and dependence on unstable nations for imported oil. Shifting away from fossil fuels may be essential within decades if citizens in the developing world achieve even a significant fraction of the per capita energy consumption enjoyed by the industrial nations. Business-as-usual or evolutionary shifts in energy consumption patterns may not be adequate. New paradigms and new energy initiatives may be required to protect the environment while providing the energy services we have come to expect. Hydrogen could play a significant role as a clean energy carrier in the future for both stationary and transportation markets. Produced from renewable energy or nuclear power, hydrogen could become the backbone of a truly sustainable energy future – an energy system that consumes no non-renewable resources and creates no pollution or greenhouse gases of any type during operation. However, to achieve this potential, hydrogen must overcome serious economic, technological and safety perception barriers before it can displace fossil fuels as the primary energy carrier throughout the world. In this paper we explore the current status of hydrogen and fuel cell systems compared to other fuel options for reducing pollution, greenhouse gas emissions and suggest the introduction of hydrogen into the energy economy.

Clean Energy Source

Nuclear power is a young technology that has developed within a political environment of ever-changing priorities. In the United Kingdom, Government-led central planning of electricity supply has given way to market forces and the future of nuclear power depends on its ability to compete in this competitive environment as well as its wider public acceptance. In only three years, the disciplines of private sector competition have transformed the economics of United Kingdom nuclear operations and the new generation of pressurized water reactor (PWR) at Sizewell is set to lead the world in safety and performance. Taken together with the growing recognition of the need to protect the local and global environment from the products of the combustion of fossil fuels, the prospects for the future of nuclear power as the major clean energy source for the twenty-first century have never been better.
