Solar steam for industrial processes

Solar steam for industrial processes

Solatom is a solar concentrator designed for generating high temperature heat (steam, hot water or thermal oil) in industrial processes. Solatom's modules are formed by rows of mirrors that track the sun, reflecting the sunlight on a vacuum tube. The fluid circulating through the tube absorbs the reflected energy producing an increase in the temperature of the fluid (up to 300 °C). Each module has a nominal power of 15 kW thermal. When more capacity is needed, the modules are joined together, increasing the total power of the plant. The system is designed for be deployed on the rooftop, with a specific weight under 23 kg/m².

Solid-state refrigerator

India's National Physical Laboratory has developed a portable, solid state cooling technology that does not require the compressor or refrigerant found in conventional refrigerators. It can therefore be operated at a low-power supply of only 75 Watts DC, e.g. directly from solar photovoltaic cells and batteries. The cooler was developed for two main applications: 

1. As a low-cost refrigerator for rural populations to store food and provide affordable comfort

2. To compliment India’s immunization program for rural populations of children by storing vaccines at low temperatures for a long time. 

With a long lifespan and needing little maintenance, the solid state cooler maintains 5 °C at an ambient temperature of 40 °C but can cool to -2 °C if required.

Speed control technology to capture slip-loss energy

Speed control technology to capture slip-loss energy

Jiangsu Cigu Science and Technology Co., Ltd produces winding permanent magnetic coupling adjustable speed drive in motor system. It is a kind of non-contact permanent magnetic drive technology which consists of permanent magnetic rotor, winding rotor and the control system. When there is speed difference between the p-m rotor and winding internal rotor, induced electromotive force will be generated in the winding. By controlling the induced current, speed control and soft start can be realized. During power transmission, the slip power is converted into electric energy to be fedback and reused, which is efficient and energy saving; completely solving the problem of temperature rise of other variable speed regulating devices.

Spinning cylinder for wind power of vessels

Spinning cylinder for wind power of vessels

Windjammers were a class of sailing vessels built from the 1870s to 1900. As engine technology developed, they were slowly phased out and replaced by steamships which were faster and could stay on schedule regardless of wind conditions. But what if the power of wind could be harnessed to create a hybrid solution for today’s modern fleets? That’s the idea behind Norsepower’s Rotor Sail Solution – a spinning cylinder that harnesses wind power to generate the thrust needed to propel vessels. When conditions are favorable, the Norsepower Rotor Sails allow the main engines to be throttled back, saving fuel and reducing emissions while providing the power needed to maintain speed and voyage time.

Stirling engine low-temperature electricity generation

Stirling engine low-temperature electricity generation

Cool Energy have developed a low-temperature Stirling engine for distributed, on-site heat-to-electricity applications. Liquid or gas heat streams are converted into mechanical energy to produce electricity. According to Cool Energy, the system differs from other Stirling engines in that it is optimized to run at lower input heat temperatures than previous engines (150 °C to 400 °C fluids or gas up to 700 °C). The engines are a new approach to the well-known Stirling cycle, employing a new engine configuration, low-cost materials, non-combustion, self-lubricating components, a nitrogen working gas, and long service life.

Stronger concrete with less cement

Stronger concrete with less cement

Cement production accounts for 6–8% of global CO₂ emissions. Thus changing the way concrete is produced is very important in abating climate change. Strongcrete technology better controls the concrete casting process and gives the concrete an improved compaction, making it possible to reduce the cement in the concrete mix by 20% and at the same time improve the quality of the concrete. Strongcrete uses a RolliT robot, a remote controlled, lightweight and electric driven machine that travels over the surface of the soft concrete. It delivers a stronger, flatter and tighter concrete surface thereby reducing very common problems like surface cracks as well as enables better bonding.

Sulfide superionic conductors in solid-state batteries

Sulfide superionic conductors in solid-state batteries

Toyota Motor Corporation and the Tokyo Institute of Technology have discovered superionic conductors with the world’s highest lithium-ion conductivity. They have used the material to develop an all-solid-state battery that it is claimed has achieved a power density three times as high as conventional lithium-ion batteries. All-solid-state batteries can be used, for example, as electric vehicle batteries or as fixed storage to support intermittent renewables, contributing to the reduction of greenhouse gas emissions.

Super-fast broadband enabled dematerialisation

Dematerialisation reflects the move to a more digital society enabled through digital communication, replacing physical objects with digital and on-line equivalents. This also includes reduction in personal travel by moving to on-line transactions. The avoided carbon emissions include: the reduction in embodied carbon from the de-materialisation of CDs, DVDs, games, books, newspapers and mail; and transport emissions savings from personal travel reductions associated with shopping (these savings are offset to a certain extent by an increase in courier/delivery travel emissions).  BT developed a methodology to quantify the carbon benefits associated with super-fast broadband (fibre-optic residential internet access), which is driving the uptake of digital distribution of goods and services.

Current avoided emissions calculated to 0.307 tCO2 per annum per residential fibre broadband connection (2018).

Sustainable pensions

Matter is a sustainable alternative to a normal pension plan that avoids investments in fossil fuels, weapons and tobacco, while more money is invested in companies working towards a sustainable future. A Matter customer can track their savings through a digital platform and see the impact of those savings. Matter claims that we have invested 4 to 5 times as much money in fossil fuels as we can afford to extract and combust if we are to avoid catastrophic climate changes. A calculator shows a Matter customer how much their savings have contributed in terms of reducing CO₂ emissions and waste production.
