Hydrogen

Falling module prices will help PV post another record year after an estimated 132 GW was installed worldwide in 2020, according to an energy transition investment trends report published by Bloomberg New Energy Finance.

The private-sector arm of the World Bank, which claims to leverage $3 of its own capital and $8 from third parties for every dollar invested in its blended finance funds, has attempted to quantify what devoting Covid recovery funds to green investment would mean for emerging economies.

A report by McKinsey & Company reinforces the widely-held view renewables will supplant fossil fuels in the energy system but also joins the chorus of voices warning the world is on track to fall well short of limiting global temperature rises this century to 1.5C.

The use of polymer electrolyte membrane fuel cells as backup power generation in solar microgrids could drive down costs and improve efficiency, according to an international group of researchers. They have proposed a new energy management system that could be ideal for hybrid solar-hydrogen microgrids in remote locations.

Researchers in Finland have demonstrated the technical feasibility of an off-grid residential PV system combined with short-term battery storage and seasonal hydrogen storage. The proposed model is applicable only to northern climates, as higher levels of solar radiation in southern locations would mean a reduced need for seasonal storage. It was tested in an existing single-family house in Finland with a 21 kW rooftop array and a ground source 6 kW heat pump.

With this, green hydrogen (hydrogen produced using renewable energy) would become cost-competitive with hydrogen from fossil fuels in certain industrial applications such as ammonia production for fertilizers.

The Energy and Resources Institute (TERI) has signed a Memorandum of Understanding (MoU) with the India arm of Norwegian energy company Greenstat to set up a Centre of Excellence for hydrogen in India and accelerate deployment of hydrogen technologies in the country.

The public sector energy company has opened a compact reformer plant at Delhi Transport Corporation’s Rajghat bus depot. The facility will produce hydrogen-enriched compressed natural gas as a bus fuel. A trial period will see 50 gas-powered buses run on the blended fuel with fuel economy and emissions monitored.

India is in mission mode on researching different aspects of the hydrogen economy, including hydrogen production, storage and utilization for stationary, power generation and transport applications. The need is to demonstrate the scaled versions at a faster rate. 

International thinktank IEEFA says there are 50 viable green hydrogen projects under development with an estimated renewable energy capacity of 50 GW and the potential to produce 4 million tonnes of the fuel annually.
