Additionally, startups are developing thin-film cells to make solar panels flexible, cost-effective, lightweight, and environment-friendly.
To improve PV performance, emerging companies are devising technologies to concentrate solar power using mirrors and lenses. Innovations in PV materials, such as the use of perovskite, are increasing energy conversion multifold. These innovations are further coupled with photovoltaic designs that enable maximum efficiency and high productivity.
Together, they promote sustainability through recycling, minimum resource utilization, and the use of alternate materials.

Its bifacial perovskite and silicon solar modules generate more power than conventional systems. Additionally, Beyond Silicon offers its modules as drop-in replacements for existing silicon PV module manufacturing processes. This enables PV module manufacturers to produce and sell high-efficiency modules, enhancing their profitability while lowering system costs.
The energy grid is one of the most complex infrastructures and requires quick decision-making in real-time, which big data and AI algorithms enable for utilities. Beyond grid analytics and management, AI''s applications in the renewables sector include power consumption forecasting and predictive maintenance of renewable energy sources.
It further enables IoE applications that predict grid capacity levels and carry out time-based autonomous trading and pricing. With innovations in cloud computing, virtual power plants (VPP) supplement the power generation from utilities. In addition, startups utilize data analytics and machine learning for renewable energy model designing and performance analysis.
German startup Likewatt develops Optiwize, a patented software solution that provides energy parameter analysis using machine learning. Optiwize also calculates historical power consumption and carbon dioxide emissions as well as features renewable energy audits and weather forecasting. This allows individual and collective consumers to observe real-time consumption patterns. Moreover, it enables power producers to hybridize different technologies and optimize load sizing.
Resonanz is a German startup that enables automated intelligent energy trading. The startup''s software tools, rFlow and rMind, integrate and manage data in real-time to create autonomous algorithmic decisions. Furthermore, the rDash interface visualizes production forecasts, market price indicators, and accounting data that aid decisions. Through these products, the startup enables market participants to increase their share of sustainable energy and returns at the same time.
DESS localizes renewable energy generation and storage, overcoming irregularity in production. Based on economic and other requirements, startups offer a range of battery and batteryless solutions. For instance, flow batteries leverage low and consistent energy, whereas solid-state batteries are lightweight and provide high energy density. For applications that require large amounts of energy, in a short period of time, capacitors and supercapacitors are also used.
Due to concerns regarding discharging, safety, and environmental pollution, startups are devising batteryless storage alternatives such as pumped hydro and compressed air technologies. On the other hand, surplus energy is converted to other forms of energy such as heat or methane for storage and reconversion through Power-to-X (P2X) technology.
Swiss startup Green-Y Energy develops compressed air energy storage technology. By increasing energy density while doubling the heat and cold extraction, the startup reduces the required storage volume as well as provides heat energy and cooling for domestic use. The process is also sustainable since water and air are the only working fluids. In addition, this compressed air is stored in durable and inexpensive commercial pressure tanks, allowing building managers and homeowners to integrate renewable energy systems.
MGA Thermal is an Australian startup that enables thermal energy storage. The startup''s product, Miscibility Gap Alloys, has a melting phase and a solid phase contact.

Moreover, the materials and containment units used are recyclable, safe, affordable, and easy to use. The large-scale storage potential of this solution enables renewable energy utility companies to provide continuous electricity even during peak hours.
Hydropower is the energy derived from moving water. Unlike solar and wind, hydro energy is predictable and, hence, more reliable. Besides, hydroelectric dams, as well as ocean-based energy harnessed from tides, currents, and waves, offer high energy density while reducing dependency on conventional sources.
The innovations in these renewable sources focus on energy converters and component improvements for harvesting energy more efficiently. Within hydropower, small-scale hydroelectric dams and tidal barrages enable decentralized energy generation.

Iranian startup GED Company offers microturbines for distributed generation of hydroelectricity from water streams like canals and rivers. The startup''s floating drum turbine (FDT) consists of an undershot waterwheel that floats on the water stream using a buoyant skid and is anchored with cables or hinged arms. The rotation of FDT by the stream produces electricity. The solution is low-cost, efficient, and ensures reliable distributed generation for electrification in remote and underdeveloped locations.
Despite being one of the oldest energy resources, the rapidly evolving nature of the wind energy sector makes it one of the major trends. Startups are devising offshore and airborne wind turbines to reduce the demand for land-based wind energy. Innovations in this field often integrate with other energy sources such as floating wind turbines, solar, or tidal energy.
To further improve efficiency, there are constant advances in the aerodynamic designs of the blades. Startups also develop efficient generators and turbines for high-energy conversion.
