A novel 5MW/15MWh liquid air energy storage system is nearing completion at a landfill waste site near the city of Manchester, England. The demonstration system will be connected to the UK grid to provide balancing services.
The system takes waste heat from the jacket around GE Jenbacher landfill gas engines and uses that waste heat to boost the expansion rate of liquefied air to power a 5MW GE turbine.
At about 10% of all EU energy use the scale of cost-effective energy savings and carbon reductions by proper application of building automation and controls is very large. To unlock this potential, there is no need for more EU regulation but rather to ensure MS implementation of existing regulations is in line with an holistic strategy to target this specific savings opportunity.
As we move into a world with increasing amounts of renewable energy on the grid, reliable, affordable and grid-scale energy storage systems are essential. Pumped hydro is one such system.
Hydro power is not only a renewable and sustainable energy source, but its flexibility and storage capacity also make it possible to improve grid stability and to support the deployment of other intermittent renewable energy sources such as wind and solar.
The UN Industrial Development Organisation calculates that 87% of Western Europe’s economically viable small hydropower capacity has been exploited. In Northern Europe that figure rises to 95%. Yet, innovative companies in niche segments are seeing opportunities in hydropower – and good growth.
MJ2, a small French hydro turbine manufacturer increased its turnover in 2014 by 44% to €10 million.
Setting Minimum Efficiency Performance Standards (MEPS) at the point of Least Lifecycle Cost (LCC) is generally considered a best practice for sustainable product policy.
However, the team at Coolproducts challenges this mantra. In their report ‘Fine-tuning the Ecodesign engine’ they find that equipment cost is often overestimated while savings potentials are underestimated, leading to sub-optimal results.
An innovative zero-emissions motor for the refrigeration transport sector powered with liquid nitrogen is undergoing commercial road trials in Central England.
Initial results from the trucks fitted with ‘Dearman’ transport refrigeration units are promising, according to the company. The Dearman systems cooled their trailers more quickly than conventional diesel-fuelled refrigeration units.
