The document defines key terms in the hydrogen economy, including production methods like electrolysis and steam reforming, storage forms such as compressed and liquid hydrogen, and the criteria for 'clean hydrogen' and 'zero-emission motor vehicles'.

The policy brief examines the nature of China's energy investments in Africa, contrasting upstream extractive projects with downstream power generation. It highlights a problematic bias toward large-scale hydroelectric dams, which the author suggests may be a way for China to export its own domestic overcapacity in dam building while ignoring environmental and geopolitical risks. The document calls for African agency in agenda-setting to transition toward greener technologies like solar and fuel cells, ensuring that investments create local jobs and support structural transformation rather than merely facilitating resource export.

The paper proposes a 'lightweighting first' strategy to drastically reduce tractive load in automobiles, trucks, and aircraft, making electric and hydrogen powertrains more affordable and efficient. It argues that integrating advanced materials like carbon-fiber composites with smarter logistics and urban planning can lead to an oil-free U.S. transportation sector by 2050, providing significant economic savings and carbon emission reductions.

The text proposes the 'Hypercar' as a solution to the inefficiencies and environmental damage of the traditional steel-based automobile industry. By combining ultralight composite materials, low-drag design, and hybrid-electric propulsion (specifically hydrogen fuel cells), Hypercars could drastically reduce fuel consumption and emissions. However, the author emphasizes that technological efficiency alone cannot solve traffic congestion or urban sprawl, necessitating a shift toward 'New Urbanist' design, market-based parking costs, and improved community planning to reduce the necessity of car travel.

The paper proposes a 'hypercar' design based on the synergy of advanced-polymer-composite monocoques, ultralow drag, and hybrid-electric propulsion. It argues that this approach can increase fuel economy by 4–10 times compared to conventional cars, potentially reaching 60–120 km/l with fluid fuels or 250 km/l with fuel cells. The author emphasizes that the primary barriers to adoption are cultural rather than technical, as the industry relies on incremental steel-based design. Strategically, the shift to composites would lower fixed tooling costs, reduce reliance on oil, and enable a transition to distributed energy systems via fuel-cell vehicles acting as power plants.

The document outlines four plausible scenarios for the year 2010 based on federal regulatory roles and financial environments. It advocates for a 'water soft path' paradigm shift, moving from centralized, demand-driven 'gray infrastructure' toward decentralized, efficient, and integrated 'green infrastructure.' The author identifies drivers for this transition, including end-use efficiency, waterless sanitation, stormwater harvesting, and technological spill-overs from the distributed energy revolution, such as fuel cells and hybrid-electric vehicles.

The paper assesses the South African TVET system's capacity to support a green transition, specifically focusing on the Green Hydrogen Economy. It evaluates the existing Centres of Specialisation (CoS) model and pilot programmes from Bambili Advisory and the National Business Initiative (NBI) to recommend a flexible, demand-led approach to green skills development. The authors argue for a 'capabilities approach' over narrow occupational competencies to ensure a just transition for youth.

The report investigates the impact of a transition to a green hydrogen economy on TVET-level employment in South Africa, contrasting domestic development with international export opportunities. It identifies key sectors for skill development—including chemicals, electrical machinery, and PGM mining—and argues that while GHE jobs are expected to grow significantly after 2030, the TVET system must address structural gaps and develop specialized curricula in fuel cell and electrolyser manufacturing to support a just transition for workers in coal and refining.

The document examines South Africa's nascent green hydrogen economy, positioning the country in the 'technological readiness' phase of market development. It argues that while some input manufacturing is emerging, there is a critical need for coordinated industrial and energy policies—including capital grants and electricity tax exemptions—to drive commercial production. A central focus is the Technical and Vocational Education and Training (TVET) sector, where the author identifies a 'wide chasm' between graduates and employment. The paper advocates for a shift toward 'anticipatory governance' and 'skills foresight' to better align vocational training with the evolving demands of the green hydrogen value chain, ensuring a just transition for workers displaced from the coal industry.

The report analyzes three scenarios—Ordinary Effort, Promoting Sustainability, and Green Growth—to model China's energy demand and carbon emissions through 2020. It finds that while industry will remain the primary energy consumer, aggressive policies in energy efficiency, fuel switching to natural gas, and the expansion of renewables and nuclear power can significantly decouple GDP growth from energy consumption and carbon emissions. Specifically, the Green Growth scenario demonstrates that carbon emissions could increase by only 50% compared to more than doubling under a business-as-usual approach, provided there is substantial investment in clean energy infrastructure and rigorous enforcement of efficiency standards across the industrial, transportation, and building sectors.

The authors propose a heuristic framework to bridge the gap between governance research and technological innovation systems (TIS). By integrating the TIS approach with the multi-level perspective (MLP) on socio-technical transitions, the framework allows researchers to analyse the causal relationship between governance arrangements—defined by who governs, how they govern, and what is governed—and the functionality of an innovation system over time. The authors argue that the effectiveness of governance depends on the TIS's stability and its alignment with existing socio-technical regimes.

The paper argues that incremental improvements are insufficient to address the unsustainability of current road transport, which is locked into a regime of oil and car dependence. Using a multi-level perspective, the authors identify three 'niches' for radical innovation: novel vehicle/fuel technologies (Niche 1), a shift from product ownership to mobility services (Niche 2), and post-industrial lifestyles that reduce overall travel demand (Niche 3). In Sweden, Niche 1 is seen as reaching a 'take-off' phase, particularly with biofuels and hybrids, supported by a history of niche experiments and targeted policies. In the UK, the transition is slower and more 'technology push' driven, though congestion charging in London is highlighted as a successful intervention. The authors conclude that a sustainable future requires the co-evolution and 'niche-accumulation' of all three pathways, as technology alone cannot solve social issues like congestion or obesity, nor can it fully mitigate climate change without demand reduction.

The document defines Renewable Energy Certificates (RECs) as tradable instruments representing one megawatt hour (MWh) of renewable electricity generation. It distinguishes between compliance markets, driven by state policies like Renewable Portfolio Standards, and voluntary markets driven by consumer preference. The text highlights the importance of third-party certification, such as Green-e®, to ensure credibility and outlines how factors like technology type and local demand influence pricing. It further clarifies that RECs differ from carbon offsets and explains the distinction between bundled green electricity and unbundled REC purchases.

The document outlines how U.S. climate policies typically target large 'smokestack' emitters and fuel importers to cover approximately 80 percent of emissions. It explains that while regulated facilities face compliance costs—such as purchasing GHG allowances—non-regulated facilities may encounter indirect costs passed through from suppliers. The text highlights that businesses can mitigate costs through energy efficiency and leverage new market opportunities by producing low-GHG technologies.
