The Hydrogen Stream: India, Saudi Arabia sign hydrogen agreement

India and Saudi Arabia have agreed to develop electrical interconnections and low-carbon hydrogen, while Masdar has partnered with Boeing ion the sustainable aviation fuel (SAF) industry.


EU cross-border solar auction largely oversubscribed

The first tender under the European Union’s new €40 million ($41.8 million) multilateral solar scheme – targeting 5 MW to 100 MW projects based in Finland and providing energy to Luxembourg – has been ‘oversubscribed’ with bids ‘significantly exceeding target volumes’, the European Commission’s Directorate-General for Energy recently announced.

Alight to build 100 MW solar plant in Finland

Swedish solar developer Alight says it will enter the Finnish PV market for the first time early next year with a 100 MW ground-mounted solar park in Eurajoki. Alight COO Warren Campbell tells pv magazine that the array will be a ‘big project by Finnish standards.’


Research shows heat pumps perform better than fossil fuel heating in mild cold climates

A British research group has aggregated information from seven field studies on heat pumps from around the world and has found air-source devices have an average coefficient of performance (COP) of 2.74 when temperatures are above −10 C. Below that, COP is between 1.5 and 2.

Scientists analyze seasonal performance of rooftop, vertical PV in the Arctic

New research from Finland shows that the best season for rooftop PV generation in the Arctic is spring, and that the best tilt angle for rooftop systems is 28 degrees. It also showed that vertical PV installations perform better in winter.

Decentralized heat pumps with district heating could cut opex by 24%

Researchers in Finland say that decentralized heat pumps could provide significant cost savings when selling surplus heat into district networks. However, they warned that capital expenditure remains high.


The Hydrogen Stream: US awards $34 million to 19 hydrogen projects

As the US and British government press ahead with their hydrogen support projects, a team from Korea and the US has developed an iridium nanostructure catalyst, which decreased the amount of the chemical element. Meanwhile, hydrogen projects are proceeding in West Virginia, Denmark, Finland, and Japan.


The Hydrogen Stream: Early adoption of green hydrogen leads to higher costs

Norwegian researchers say blue and green hydrogen could complement each other in the future, but early adoption of green hydrogen could result in increased hydrogen production and emissions.


Recirculate – giving EV batteries a second-life

With the rapid growth in electric vehicle (EV) demand bringing fears of a mountain of EV battery waste piling up further down the line, the EU-Swiss government-funded Recirculate program is planning how to keep batteries in use for much longer before they head to recyclers.


Hybridizing PV, sand storage, solar thermal energy for steam generation

A Finnish-Swedish consortium has designed a hybrid system that uses photovoltaics and solar thermal energy separately to provide steam to industrial facilities. The PV unit is coupled to a sand-based thermal storage system and reportedly contributes to lower the levelized cost of energy of the entire system.
