Wave and tidal energy are forms of renewable energy harnessed from the movement of ocean waters. Wave energy captures the kinetic energy of ocean waves, converting it into electricity using devices such as oscillating water columns or point absorbers. Tidal energy harnesses the gravitational forces between the earth, moon, and sun, generating power as tides rise and fall. Both sources have the potential to provide sustainable and predictable energy, reducing reliance on traditional fossil fuels.

Underfloor heating is used to heat the floor as well as the ambient surroundings, utilizing an underfloor warm water pipe or an electric cable. The heat from an underfloor heating system travel from the ground to cool the above-head level, thus ensuring uniform heat distribution. An underfloor heating system helps in controlling indoor climatic conditions by elevating the surface temperatures. The thermal comfort provided by these systems eliminates the need for radiators or other heating systems.

Lighting refers to the deliberate use of light to achieve various practical or aesthetic effects. It encompasses both artificial light sources, such as lamps and fixtures, and natural light, which can be harnessed through architectural features like windows and skylights.

The Global Hydrogen Review is an annual publication by the International Energy Agency that tracks hydrogen production and demand worldwide, as well as progress in critical areas such as infrastructure development, trade, policy, regulation, investments and innovation

Industrial lighting refers to the specialized illumination systems designed and utilized within industrial facilities such as manufacturing plants, warehouses, and production or assembly lines. These lighting solutions are engineered to meet the unique challenges and requirements of industrial environments, providing adequate brightness, uniform coverage, and durability to support various operational tasks. Industrial lighting fixtures often incorporate robust materials such as high-impact polycarbonate or aluminum, and may feature resistance to dust, moisture, or extreme temperatures. Additionally, these lighting systems are tailored to enhance worker safety, productivity, and visual comfort, while also contributing to energy efficiency and cost-effectiveness within industrial settings.

High purity gas refers to gases that have been refined to remove impurities, achieving purity levels typically above 99.99%. These gases are essential for applications requiring precise and controlled environments, such as in electronics manufacturing, healthcare, and others, ensuring optimal performance and reliability.
