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.

Green-Y Energy offers Mechanical Energy Storage

Swiss startup 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 produces Thermal Energy Storage Material

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.

4. Hydropower

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.

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.

5. Wind Energy

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. The sustainability of blade material is one of the challenges the industry faces today. To tackle this, startups are creating bladeless technologies and recyclable thermoplastic materials to manufacture blades.

6. Bioenergy

Bioenergy constitutes a type of renewable energy derived from biomass sources. Liquid biofuels with quality comparable to gasoline are directly blended for use in vehicles. To achieve this quality, companies improve biofuel processes and upgrade techniques. The majority of biofuel conversion processes like hydrothermal liquefaction (HTL), pyrolysis, plasma technology, pulverization, and gasification use thermal conversion for obtaining biofuels.

Further, upgrade techniques like cryogenic, hydrate, in-situ, and membrane separation are used for removing sulfur and nitrogen content. Similarly, the fermentation process produces bioethanol which is easy to blend directly with gasoline. Fermentation also has the ability to convert waste, food grains, and plants into bio-ethanol, thereby providing feedstock variability.

Energy-dense feedstocks result in optimum fuel quality. For this reason, startups and big companies consider algal and microalgal feedstocks for use in the aforementioned conversion processes.

Phycobloom produces Algal Bio-Oil

is a British startup that uses synthetic biology to produce bio-oil from algae. The startup’s genetically engineered algae release this oil into the surroundings. Since the same batch of algae is reused, it makes the process fast and inexpensive. Considering that algae require only air, water, and sunlight to grow, this technology also closes the loop between greenhouse gas emissions and fuel production. The startup’s solution thus lowers the dependency of the transportation sector on fossil fuels.

Bioenzematic Fuel Cells (BeFC) provides Paper-based Biofuel Cell

French startup generates electricity using a paper-based biofuel cell system. The system combines carbon electrodes, enzymes, and microfluidics. The enzymes convert glucose and oxygen into electricity using a miniature paper material. The technology is suitable for low-power applications, like sensor data collection and transmission.

7. Grid Integration

Grid integration technologies primarily include transmission, distribution, and stabilization of renewable energy. Scaling up variable renewable energy generation is often far from demand centers which results in transmission and distribution losses. To overcome this, energy-efficient, grid electronic technologies such as Gallium Nitride (GaN) and Silicon Carbide (SiC) semiconductors are leveraged.

The challenge of frequency and voltage fluctuation due to variable renewable energy generation is solved through microcontroller-based solutions. Despite these technologies, stabilization of the grid is a huge challenge due to intermittent energy usage. Vehicle-to-grid (V2G) technology empowers the stabilization of the grid during peak hours while grid-to-vehicle (G2V) solutions leverage the vehicle as a storage unit. As a result, both the energy and transportation industry benefits.

This enables the generation and transmission of large-scale renewable energy, empowering utilities to easily transition to cleaner fuels.

8. Green Hydrogen

Hydrogen gas has the highest energy density of all fuels and produces near-zero greenhouse gas emissions (GHG). However, most hydrogen is derived from non-renewable sources in the form of grey and brown hydrogen. In the past decade, developments in renewable energy and fuel cells have pushed the shift to green hydrogen. While cleaner, it also struggles with the problems of low energy conversion efficiency of fuel cells and challenges in transportation. For these reasons, the developments in green hydrogen focus on improving hydrogen storage, transport, and distribution.
